DIY fuel dispensing crane repair

Elimination of malfunctions of fuel dispensers of gas stations

Maintenance personnel should be aware of possible column malfunctions and how to fix them.

Faults can be divided into two groups:

• related to violation of regulation, eliminated on site;

• associated with wear, eliminated by replacing parts and repairs (see table. 3.17).

As column wear increases, column performance decreases and readings are out of tolerance. Renovation required. Premature wear occurs due to improper operation, in the absence of: maintenance, timely prevention and preventive maintenance. Parts can fail as a result of breakdowns occurring mainly due to fatigue in the material or physical effects on parts if they are not properly disassembled and assembled.

Possible malfunctions of the fuel dispenser and ways to eliminate them

Regularly check the valve by visual inspection for mechanical damage. Pay particular attention to the presence of burrs at the outlet of the vacuum channel (2). Checking the automatic shutdown is carried out on the crane operating at low performance (position 1/3 of the lever (9)) by immersing its nozzle in the fuel. The crane does not require lubrication during operation.

The tap does not open: The pump pressure may be too low to overcome the force of the poppet spring (6)

If the pump pressure cannot be increased, disconnect the valve, remove the filter pivot (8), move the lever (9) to the open position and push the stem (7) to release the poppet valve.

The tap does not turn off automatically: The vacuum in the vacuum chamber is too low to automatically shut off the tap.

With the pump running, fully press the lever (9) to control the achievement of the maximum fuel flow through the cock. Make sure that the vacuum channel (2) is not damaged, the cover of the vacuum chamber (5) is not damaged, the diaphragm (4) is not defective and the filter (8) is clean. Eliminate the cause of the drop in vacuum in the vacuum chamber.

The crane constantly turns off: The vacuum channel (2) is blocked.

First check that the ball (3) in the ball valve moves freely. This can be established by shaking the tap according to the characteristic sound. To clean the vacuum channel (2), blow it out with compressed air.

Repairs to the Certus column must be carried out by qualified personnel in accordance with GOST R 52350.19-2007 (IEC 60079-19: 2006) “Explosive atmospheres. Part 19. Repair, inspection and restoration of electrical equipment ".

Under certain operating conditions, for example, in the presence of impurities in the process pipeline, malfunctions may occur, the elimination of which requires the help of qualified technicians who are well versed in the design and operation of the pump unit. Since it is impossible to list all pumping unit malfunctions, below is a list of the most common problems, their causes and remedies.

SOLENOID VALVE FAULTS

1. Defective solenoid coils - apply voltage to the coil. A metal click in the core of the electromagnet signals that the coil is in good condition;
2. Nlow supply voltage of electromagnets - The voltage should not be less than 85% of that indicated on the valve's information plate;
3. Incorrect fluid pressure - check the working pressure, it must be within the range indicated on the information plate of the valve;
4. Working fluid leak - disassemble the valve and clean all parts. Replace defective parts with spare parts.

DISPENSING CRANE FAILURES

The tap does not open: The pump pressure may be too low to overcome the force of the poppet spring (6)

If the pump pressure cannot be increased, disconnect the valve, remove the filter pivot (8), move the lever (9) to the open position and push the stem (7) to release the poppet valve.

The tap does not turn off automatically: The vacuum in the vacuum chamber is too low for the automatic shutdown of the valve.

With the pump running, fully press the lever (9) to control that the maximum flow of fuel through the cock is reached. Check that the vacuum channel (2) is not damaged, the cover of the vacuum chamber (5) is not damaged and the filter (8) is clean. Eliminate the cause of the drop in vacuum in the vacuum chamber.

The crane constantly turns off: The vacuum channel (2) is blocked.

First check that the ball (3) in the ball valve moves freely. This can be established by shaking the tap according to the characteristic sound. To clean the vacuum channel (2), blow it out with compressed air.

In accordance with the purpose and nature of the work performed, there are three types of column repair:

Maintenance provides for their partial disassembly, restoration or replacement of worn out and broken parts. The need for current repairs is identified during preventive maintenance and during operation. During the repair process, the necessary adjustments are carried out.

Medium repair provides for the replacement or restoration of one or more units (assemblies), as well as basic parts with the implementation of technologically more complex operations than in the current repair.

Current and medium repairs are carried out directly at the installation site of the column. In this case, it is advisable not to disassemble the unit (unit) that has failed, but to replace it with a new, repaired one from the exchange fund. With this method, the repair is accelerated, and the failed unit (unit) is repaired in more convenient conditions in the workshops.

Overhaul aims to restore all technical parameters. During a major overhaul, the column is subject to complete disassembly and repair or restoration of all units. Overhauls are usually carried out in workshops or in a factory.

Routine and medium repairs are usually carried out by the mechanics of the gas station. The workplace of a mechanic must be equipped with everything necessary to ensure high-quality and quick maintenance and repair. It should have a bench with a vice, a rack for storing parts and assemblies, a set of fitter's, assembly tools and accessories, and standard measuring instruments of the 2nd category with a capacity of 10 and 50 liters.

In the interests of the clearest organization and better conduct of repair work, the following order is usually followed:

· Establishing the sequence of disassembly;

· Disassembly of equipment into units and parts;

· Identification of the nature and magnitude of wear of parts, their rejection and determination of parts to be replaced;

· Choice of methods of restoration of worn-out parts;

· Assembly of units and equipment with the necessary adjustment;

· Check, adjustment and calibration.

Malfunctions are detected by external examination of the equipment and its individual units, by interrogating the persons working on this equipment, as well as by the control start-up of the column.

OIL DISPENSING COLUMNS

3.3.1. DEVICE AND EQUIPMENT

Requirements for oil dispensers are defined by GOST 4.103: nominal oil consumption must be ensured at a suction height of at least 3 m, a dispensing valve height above ground level up to 2 m and the location of individual dispenser blocks at a distance of up to 20 m; filtration fineness should be 250 µm.

An oil dispenser with a pumping unit is mounted in a heated room, since they can only operate at temperatures not lower than + 8 ° C.

The column consists of (Fig. 3.13):

· A dispensing tap with a sleeve.

OIL METER - piston type, four-cylinder. Designed to measure and record the amount of oil dispensed according to the indications of the arrows and the total counter. One full revolution of the large arrow produces 1 liter, and one full revolution of the small arrow produces 10 liters of oil. The final results of dispensing are shown by the total counter of the roller type with a maximum measurement limit of 999.9 liters. After each dispensing, the hands are manually set to the zero position.

PUMPING UNIT consists of a gear pump driven by an electric motor, a hydraulic accumulator, a filter, a circuit breaker with a pressure gauge, a check valve and a safety valve. The entire unit is mounted on a cast iron plate. A valve with a coarse mesh filter is installed on the suction line. The main filter is mounted on the pump discharge line. The filter has a plug for draining the oil from the system and removing air from the suction line.

The hydraulic accumulator is connected by a pipeline with a plunger-type automatic switch, which serves for automatic control of the electric motor during the operation of the pumping unit.

The pressure gauge is designed to monitor the pressure in the accumulator and to adjust the circuit breaker and safety valve.

The electric motor turns on and off automatically using a magnetic starter.

The safety valve is adjustable within 1.6. 1.7 MPa to protect the hydraulic system in the event of a circuit breaker malfunction.

When dispensing oil, the pressure in the system is maintained at 1.2. 1.3 MPa. When dispensing is stopped, when the dispensing valve is closed, the pressure in the system rises to 1.4. 1.5 MPa. This opens the circuit breaker contacts and the motor stops. The pressure in the system is maintained by a hydraulic accumulator. When dispensing oil again, when the dispensing valve is open, the oil is first dispensed by the pressure in the hydraulic accumulator. At the same time, the pressure in the system drops. When the pressure drops to 0.8. 1.0 MPa, the contacts of the circuit breaker close again and turn on the pump motor.

To fill the hydraulic system with oil and remove air from it, unscrew the plug from the tee of the suction pipe and pour oil through the opening into the suction pipe and pump. Then screw this plug, and unscrew the filter plug by 2-3 turns and turn on the pumping unit.

Rice. 3.13. Flow diagram of a small dispenser:

1 - pressure gauge; 2 – circuit breaker; 3 - safety valve; 4 – counter; 5 - mesh filter; 6 – a dispensing tap with a sleeve; 7 - gear pump; 8 - electric motor;

9 – check valve; 10- hydraulic accumulator; 11 - filter; 12- column case

Installation features:

· The pumping unit is mounted in the immediate vicinity of the oil tank in a room providing a temperature not lower than +17 ° С;

· The location of the pumping unit must ensure a minimum suction lift and stable operation at a temperature of +8 ° С;

The hydraulic system is filled with oil, for which it is necessary: ​​unscrew the plug from the tee of the suction pipe and fill in oil, screw the plug on the tee and unscrew the plug on the filter by 2-3 turns, turn on the unit until clean oil without air bubbles comes out of the filter, and screw the plug ...

After installation, the oil dispenser is checked for tightness, accuracy of oil release and performance.

Preparation for work:

· Fill the hydraulic system with oil and remove air; to do this, unscrew the plug from the tee of the suction pipe and fill in oil;

· Wrap the plug and unscrew the filter plug by 2-3 turns;

· Turn on the pumping unit;

After that, the oil will flow in an even stream, without air bubbles, i.e. after filling the hydraulic system with oil, the electric motor is automatically turned off;

· Remove air from the meter, for which: remove the oil column cover and unscrew the plug located in the vertical plane of the block between the two upper cylinders by 3-4 turns; after the oil has flowed out without air, wrap the plug. When the shut-off valve of the dispensing valve is closed, the pressure in the system should not drop;

· Turn on the column and make sure that the pump, meter and dispensing valve are working properly.

During a test run, it should be borne in mind that the total counter shows the cumulative total of the released oil and cannot be returned to its original position.

Service personnel must check the joints and seals and, in case of oil leaks, repair the leak.

It is forbidden to operate a column with a meter error exceeding the norm established by the operating documentation.

Oil release procedure:

· Set the zero position;

· Remove the dispensing valve from the hole in the column housing and insert its tip into the neck of the crankcase. By pressing the handle of the dispensing valve, open the shut-off valve and refuel;

· Control over the amount of oil dispensed is carried out by observing the readings of the counting device arrows;

· The electric motor stops automatically after the required dose is released and the shut-off valve is closed;

· After the end of the oil dispensing, insert the dispensing valve into the hole of the dispenser body.

Possible column malfunctions and methods of their elimination are given in table. 3.18.

Metrological and technical services

4.1 During commissioning, as well as periodically during operation, the column must be subject to mandatory State verification.

Periodic verification of the column should be carried out in accordance with the requirements set out in

Pr 50.2.006-94, according to the method described in MI 1864-88 “Fuel dispensing columns. Verification method. " and

5.1 Routine repair of the column should be entrusted to qualified personnel.

Carry out the current repair of components according to the operational documentation supplied with the column.

The grounds for the delivery of the column or its individual units for repair, the data on the repair and its acceptance from the repair are recorded in section 19.

5.2 Repair of the monoblock pump.

5.2.1 Replacing the pump blades.

To replace the pump blades, it is necessary to remove the pulley from the pump shaft of the monoblock, unscrew 4 nuts from the studs and remove the flange. Remove the pump cover, take out the rotor shaft and remove all the vanes, or, without removing the rotor shaft, remove the vanes one by one with tweezers. Install the blades with grooves in the direction of rotation. Reassemble in reverse order after replacement.

5.2.2 Replacing the pump sealing lip.

To replace the pump seal, it is necessary to remove the pulley from the pump shaft of the monoblock, unscrew 4 nuts from the studs and remove the flange. Remove the pump cover from the shaft. Remove the bearing cover by unscrewing 3 screws M 4. Pull out the bearing, remove the washer and the collar behind it. Install the oil seal using a sleeve bearing mounting mandrel. When pressing the cuff, the support for the cover should be no more than 100 mm in diameter, so as not to break the stop collars of the cover, i.e. the cover should rest on the device with a plane, and not with the flange of the lock. Then, putting the cover on the shaft, install it on the pump casing, insert the washer, the bearing, and close the bearing cover with the thrust sleeve.

5.2.3 Assembly and disassembly of bearings.

To dismantle the front bearing, it is necessary to remove the pump cover in the sequence described in the previous paragraph of the instructions, and after removing the cover, remove the bearing. Assemble in the reverse order, after putting the cover on the shaft.

To dismantle the rear bearing, it is necessary to remove the pump from the monoblock. To do this, it is necessary to remove the pulley from the pump shaft of the monoblock, unscrew 4 nuts from the studs and remove the flange. Remove the pump from the monoblock housing. Remove the pump cover, take out the rotor shaft.

Place the pump casing on a stand for pressing in the bearings (sketches of the accessories are shown in Fig. 14) and press out the bearing using a mandrel for dismantling.

To press in a new bearing, it is necessary to place the pump casing on a support for pressing the bearings with the inside up. Using a bearing crimping pliers, crimp the bearing, install it over the hole and press in the bearing with a press-in mandrel.The bearing should not protrude above the surface of the housing and should not sink more than 0.5 mm from the surface. Reassemble in reverse order after replacement.

5.3 Search for the consequences of failures and damages of the column should be carried out in accordance with Table 6 "Possible malfunctions and methods of their elimination" of this manual.

After eliminating the failures and damages, adjust (align) the volume meter in the following order:

- remove the seal and the wire of the seal;

- loosen the lock nut, use a screwdriver to turn the adjusting screw clockwise - to decrease the dispensed volume, counterclockwise - to increase the volume, and then tighten the lock nut.

When one adjusting screw is turned by 1/4 of a turn, the volume of dispensed fuel changes by about 50 cm 3 when dispensing a 10-liter dose.

The dispensed volume of fuel for one complete revolution of the crankshaft is equal to 4´125 cm 3 = 500 cm 3.

The correctness of the adjustment (alignment) is determined with the help of standard measuring instruments of the II category of GOST 8.400-80.

5.4 Method of electronic adjustment of fuel dispensers with readout device "Agat-4K".

Electronic adjustment is carried out either from the control panel "Agat 12mk4" or from a computer program.

1. Preparing the fuel dispenser for electronic alignment.

To carry out electronic adjustment, it is necessary to take the fuel dispenser out of the trading mode. Then you need to open the front cover of the unit and remove the screen with the display modules.

Thus, access to the lock cylinder must be provided, which is sealed with the seal of the representative of Rostekhnadzor.

2. Carrying out electronic alignment.

1) Remove the seal on the housing of the reading device control unit and open the lock cylinder. Insert the key from the speaker kit (the key is strictly individual and therefore subject to strict storage) and turn to position 1.

2) Enter the access code (1234 by default).

3) View the adjustment factor for each of the channels.

4) Carry out a control filling of fuel into a 10-liter measurer at least 3 times for each channel of the reading device. Calculate the arithmetic mean of the three fillings.

The adjustment factor is calculated using the formula:

Where: Vm - the volume of the product in the measure,

Vк - reading of the reading device.

C1 - value of the previous adjustment factor.

5) Enter the adjustment factor.

6) Carry out the filling of the dose into a ten-liter measuring vessel, if necessary, repeat the process of calculating the adjustment coefficient.

7) At the end of the adjustment work, it is necessary to write down the serial number of the adjustment in the column form. This factor will be increased by "1" for each dispensing valve every time an adjustment is performed or the adjustment password is changed.

8) Return the key to the "0" position and pull it out. Seal the lock cylinder. Install the screen and close the block case.

9) Enter the column into trading mode.

5.5 Method of electronic adjustment of fuel dispensers with reading device "Topaz 106K2-2MR".

The adjustment consists in the introduction of an adjustment coefficient into the control unit through the control unit. When taken into account, the readings of the block will exactly coincide with the measurement results (using standard measuring instruments) of the actually dispensed amount of the product. This K factor can take values ​​from 9000 to 11000 and is stored in the control unit.

When carrying out a test release, you need to set the dose in such a way that the readings of the meter were in the range from 1 to 60 liters. The resolution of the column impulse counting should be 0.01 liters / impulse.

The readings of the device Q (in liters) are determined by the counting discreteness d, the number of received counting pulses N and the adjustment factor K according to the formula:

With a value of K = 10000 and counting discreteness d = 0.01 liter / pulse, one counting pulse is 0.01 liters.

Access to the adjustment operation is limited by a four-digit password stored in the device, as well as by the “Setup / Operation” toggle switch located on the rear panel of the device.To control unauthorized changes in the adjustment coefficient, the device has a non-resettable counter for the number of adjustment operations.

In the event of a software update of the device, the adjustment counter and the password take initial values ​​equal to zero and 1234, respectively. Therefore, it is necessary to take into account whether software updates have been made, for which the device maintains a software update counter.

Before starting a new adjustment, if necessary, you can compare the readings of the counters of the number of adjustment operations and software updates with the entries in the log. The coincidence of the counters with the records will indicate the absence of unauthorized manipulations with the adjustment parameters.

If the adjustment password is lost, the reading device software must be updated (password 1234 will be set).

ATTENTION! It is impossible to directly enter the value of the adjustment coefficient into the block - the reading of the measurer is entered through the control system.

Procedure for volume adjustment:

a) Set the toggle switch of the “Setting / Operation” device to the “Setting” position.

a) Select the network address of the sleeve and the size of the control dose in accordance with the requirements. As an example, let us take sleeve No. 2 and a control dose of 10 liters; the Topaz-103MK1 controller is used as a control system.

b) Set and dispense the selected dose into the measuring vessel in the usual manner.

c) Enter the main menu, select the “Adjustment settings” section, press the à key. Enter the access code on the numeric keypad first (by default 123456), then the adjustment password (by default 1234), press the à key.

d) Enter mode 01 (selection of the sleeve network address) by pressing keys 1, Ã. Enter the network address of the desired sleeve (for our example, the second one) and exit the mode by pressing the C, 2, Ã, Ã keys.

e) Enter mode 03 (input of the adjustment factor) by pressing keys 3, Ã. Enter the readings of the test measure in milliliters (for example, 10250 ml) as the adjustment factor. To do this, press the keys 1, 0, 2, 5, 0, Ã.

If the adjustment factor is successfully changed, the controller will display the message “Parameter written”, in case of failure, the message “Write error” will appear, and if there is no communication with the device - “The device does not respond”.

Possible reasons for failure include:

- adjustment is carried out without preliminary control dose release;

- adjustment is not supported by this device;

- the toggle switch of the “Setting / Operation” device is in the “Operation” position;

- wrong network address of the sleeve;

- incorrect adjustment password;

- exit of the measurer readings beyond 1000 - 60,000 ml;

- the adjustment factor is out of the permissible range.

To check the range, you can calculate the expected ratio value using the following formula:

,

where K0 is the current value of the adjustment coefficient,

M - readings of the measure in milliliters,

D is the specified dose in milliliters.

If the calculated value, taking into account rounding, does not fit into the range from 9000 to 11000, then the regulation limit has been reached.

To reduce the time for subsequent adjustment, the device allows you to store two adjustment coefficients (for different periods of the year). The choice of one of the preset values ​​of the coefficient is made by the switch “S3”, in position “1” of which the first preset value of the coefficient will be applied, in position “2” the second.

After setting and adjusting the device, fix the toggle switches with a retaining plate (S2 in the “Operation” state, S3 in position “1” or “2” depending on the period of the year) and seal through the holes in the screws securing the retaining plate and the product cover.

If necessary, you can change the adjustment password. To do this, you need to perform the following actions (the “Topaz-103MK1” controller is used as a control system):

a) Enter the main menu (press the F key for at least two seconds), select the “Adjustment settings” section (using the # or $ keys), press the à key. Enter the access code on the numeric keypad first (by default 123456), then the adjustment password (by default 1234), press the à key.

b) Enter mode 02 by pressing keys 2, Ã. Enter four digits of the new adjustment password (eg 5678) and exit the mode by pressing keys 5, 6, 7, 8, Ã. The new password must be different from the current one. If the password has been changed successfully, the message “Password written” will appear on the controller display.

c) Exit from the menu by pressing the F key.

The main goal that was considered today is the components for the fuel dispenser, and to be precise, in the fuel dispensing nozzles. The initiators of this event tried to deal with important issues, which, as a rule, are resolved by the owners of gas stations and other specialists. So, the crux of the question was this: which is the best fuel dispensing gun, the best fit.

It should be noted right away that, practically, all pistols can modify each other. But, today, they are no longer producing the dispenser cranes, as well as spouts.

Manufacturers from European countries or from Turkey are trying to complement their equipment with different accessories, but only those that were released in Europe. Well, also, components can be used that are released under the LZV brand.

Not so long ago, the Czech Republic was part of the socialist camp, which produced HEFA fuel dispensing pistols, and today, it produces components for Adast dispensers.

Fuel dispensing valves of the fuel dispenser are used in the following manufacturers, such as:

- Dresser Wayne (Divisions of Sweden and Germany);

- Tokheim (Division from Belgium);

- Zalzkotten (German division);

- Sheid & Bahmann (Germany and others).

But, you need to know that in the USA, not a single manufacturer of fuel dispenser pistols produces components for ZVA. The pistols produced by EMCO WHEATON are perfect for Dresser Wayne, Tokheim, Schlumberger and other American equipment.

; This author has tried to organize a competition between such manufacturers that produce fuel dispensing guns:

Elaflex - ZVA Slimline model (Germany model);

The main part of the dispenser is the fuel dispensing valve, which allows the passage of fuel into a tank or other container that is intended for this. Nevertheless, the author believes that the main points that characterize the work are:

- the resistance that is obtained in the circuit;

- the work that the fuel pistol cutter does;

- stability and wear of equipment.

1. A fuel dispensing pistol is, in fact, a unit that is in a hydraulic purpose and represents a kind of obstacle. To overcome this obstacle, you will need a shopping mall, make some efforts. That is why, each pistol has a certain power, which consumes a certain amount of fuel, over a certain period of time.

Hence the logical conclusion that a pistol is better because it creates minimal obstacles.

1. The next is the work that the cutter does. In fact, a cut-off valve is an emergency valve that prevents oil products from entering the fuel tank.

The quality of the pistol very much depends on which pistol and also which company makes it.

1. Well, the last factor that affects fuel dispensers is wear.

This characteristic is not independent, but rather complements the previous two, since it greatly affects the operation of the entire system, which is especially important when working with low temperatures.

Making a conclusion, according to the first indicators.

We can observe data that we get experimentally that is different from what we get from manufacturing companies.

In principle, there may be the following explanations for this factor, now, we will consider the main ones:

- the quality of the tests themselves, which are carried out by the companies;

- tests that are carried out not by manufacturing companies, but by other companies that are also interested in this;

- the purity with which the experiment takes place;

- interest in the positive result of the experiment.

SLAM-SHUT, ITS OPERATION, AND FUEL DISPENSER GUN.

Making the experiment, as well as the analysis that is carried out after its completion, our company focused on all the data that it received as a result.

The work that the cutter did under different temperature conditions, for example, first at low temperatures, then at high temperatures, the result was recorded.

The cutter did not work at the AKT fuel pistol, but only in those cases when the fuel output was not lower than 20 liters / minute. If we talk about other manufacturers, these parameters are even less, for example, ZVA, Hefa - below 8 l / min., Emco Wheaton - below 10 l / min., OPW - below 12 l / min.

The final estimate that can be made based on the fuel dispensing nozzles.

This all suggests that pistols from brands such as ZVA, Heaf and Emco Wheaton perform best. With this in mind, we can say that the range of operation of the dispenser pistols in Ukraine has a minimum load. If we examined the main technical issues for these pistols, then it will be possible to inspect their cost, performance, and so on.
