Bork juicer DIY repair

Details: bork juicer DIY repair from a real master for the site my.housecope.com.

The basis of the juicer is the engine. Today, asynchronous, collector electric motors are used. No wonder - the technician knows no other. Actually, repairing juicers with your own hands of frequencies is faced with the situation of a failed engine. It is almost impossible to replace the mechanical part, devices operating on the basis of meat grinders break couplings, plastic bushings when a bone hits, hydraulic presses have a lot of fiddling with the oil system. Let's consider the questions, do not wait for a detailed guide, but we will consider the main types of faults in sufficient volume.

We hope that reading the review will help our readers to fix the juicer of their choice on their own. Nothing complicated inside. Don't be intimidated by the upcoming renovation of Scarlet's juicer.

Repair of the Rossoshanka, Santos juicer - the difference in the price of the product is 30 times - there is a motor inside. Rossoshanka does not work for long, noisy, the essence is the same. The properties of the juicer are determined by the design of the mechanical part.

The advantages of induction motors are considered to be simplicity of design, maintenance, high efficiency. Less noisy than collector ones, however, when powered with a voltage of 50 Hz, it is difficult to get rpm above 3000 rpm. Juicers consider this a serious limitation, Santos has a fairly large centrifuge diameter. Let's describe Rossoshanka, Neptune, and other domestic high-performance juicers in a similar way.

Collector ones are devoid of restrictions, they turn out to be smaller in size. Lose in other important professional juicers:

Noise level.
Short period of continuous operation.

On the shaft of electric motors, we see impellers blowing over the stator coils. It is made to cool the windings during operation. If, when disassembling the juicer, it was found: there are no elements inside, it is possible to supplement the structure by wisely choosing the shape of the blades. Will soften the thermal modes of operation of the electric motor. From the above it follows: asynchronous motors are preferable for the manufacture of high-quality juicers, it remains to solve the problem of speed.

In the case of centrifugal models, the issue is leveled by an increase in the diameter of the working chamber. As a result, with increasing distance from the axis, the centrifugal force increases. It is permissible to reduce the speed of the juicer motor without loss of quality.

Each device is supplied with a set of speeds. In asynchronous motors, it is realized by proper separation of the stator coils. Not all work at the same time, the result is a variation in speed. The scheme is often implemented, it consists in the correct commutation of the electrical circuit with buttons. The technical solution has great reliability, durability, and fault tolerance. A positive point. As for the speed, you can increase it using an inverter in the circuit. It is clear that it will lead to an increase in the price of the device at times. Smooth speed control can be achieved.

As for asynchronous motors, it's easy to do. Amenable to adjustment, avoiding complex circuits. Losses are reduced if the windings are supplied with direct current. Inductive resistances have little effect. The minus is small: a complex power supply is required, which reduces the efficiency of the juicer. The listed key points must be clearly understood if there is a desire to replace the engine. Readers can insure against winding burnout by bothering to include a thermal fuse at 135 degrees Celsius in the circuit. The element must fit snugly against the winding.Ideally, the thermal fuse is recessed between the turns of the wire. Provides heat exchange.

Forced cooling will not interfere. How it is done in the case of juicers, any devices, have already been told. You can borrow an induction motor starter relay from the refrigerator, along with the motor. There are two subtleties here:

In juicers, a starting winding is rarely used; a scheme with dividing the stator coils is used.
The motor type must match the relay, the overheating protection will not work.

There is a weak point in cheap juicer models: they are not protected against engine burnout. Why not put a relay like a companion for refrigerators. A difficult question, we leave it to the readers to decide on their own. The cost of other freezers is an order of magnitude (!) Lower than top-end juicers. The refrigerator works day and night, avoiding begging for the required break, does not turn off in summer. The power of the device is considerable.

For our reasons, reliable technology is closer to nature, figuratively speaking. This is directly confirmed by the design of the Norwalk juicer. So in a refrigerator, often all sensors have nothing to do with electrics, much less electronics. We need more bimetallic plates, thermocouples and other reliable and simple equipment. By the way, gas water heaters do just that, even ignition on a piezoelectric element. In this case, the technique works for a long time, is reliable and efficient. Overheating of the windings is easy to assess by the temperature of the magnetic circuit. Why isn't this done in juicers? Unable to answer this question.

What about Norwalk? Do-it-yourself juicer repair in this case is closely related to hydraulics, which was already mentioned at the beginning. Design:

There is a high-speed engine inside.
The auger is put on the shaft according to the principle of action of a meat grinder.
The ground cake is put into a bag and placed on the table of the hydraulic press.
The oil cylinder is driven by a belt drive, as in washing machines.

Thanks to a clever solution, the compressor is devoid of electrical parts. Steel block with spacers. The motor, on the other hand, is made in the best traditions of the machine. One glance is enough to understand: in 5 minutes it will not ask for rest, imitating Zelmer. In light of the above, we believe that it is enough to find a Norwalk screw juicer attachment instead of a meat grinder, having received an excellent device for a long-term operation. According to domestic GOST, it means that the equipment can withstand merciless operation during a work shift (8 hours).

The hydraulic unit will need to be filled with new oil periodically. The old is merged first. After removing the cylinder cover, it is supposed to remove the internal mechanism with a return spring, scoop out the oil. Keeping the position, the compressor drive starts. Gradually the oil will be in the cylinder. The new is poured three-quarters of an inch below the lid. Will the air gap interfere with the work? The masters say: powerless to harm. You will need to monitor for leaks of fittings, compressor, cylinder. Add, the return of the table to its original position is carried out by a spring after pressing the handle of the release valve.

If it comes to attachments for meat grinders, you will have to change plastic gears, couplings. They come in the amount of 2-8 in the kit, sometimes you have to buy new ones. Steel gears of meat grinders-juicers are rare, there is a chance of failure of a precious engine. You wonder how industrial units work ...

It is clear to readers that the main types of faults relate to the engine. First check the power supply, then the continuity of the windings begins. Having localized the malfunction, they try to rewind the coils. In the case of a collector motor, doable, the stator is a dull choke strung on a magnetic circuit. The manifold motors are called for each position of the section until the drum completes a full revolution. The rotor of the squirrel-cage induction motor is incapable of burning.The current is small, copper wire is often inseparable from the base of the "squirrel cage" by insulation. The device of the juicer is so primitive, the mechanics (bearings, oil seals, gears) and the drive break down.

The repair of power supplies has been talked about more than once. Impulse sources are found in expensive models equipped with the rudiments of intelligence.

Do-it-yourself juicer repair is not something fantastic. The device is quite simple and practically indistinguishable in different models. Whether it is a domestic juicer Dachnitsa or an imported one Bosch, they all work on the same principle, and are arranged in approximately the same way... With some knowledge in mechanics and electrics in stock, you can safely pick up a tool.

Juicer breakage is a common occurrence. This is not surprising, because such dacha paraphernalia experiences enormous stress during the harvest season. At the heart of every fruit and vegetable juice device is ordinary press... It doesn't matter in what form it is presented. The manual citrus juicer works by pressing and turning the fruit. The mechanical juicer is supplemented with units that allow to reduce physical efforts of a person and ensure greater productivity.

In any case, a decent load falls on the devices, and the increase in parts raises the percentage of breakdowns of the devices used. Even a manual juicer, presented as a press, where the pressure on the piston is produced by the rotation of the screw - and it is not always able to work reliably for a long time.

Repairing manual juicers is not that difficult. If we talk about electrical models, then the range of breakdowns is significantly expanded here. The search for a breakdown must be done in two directions: mechanics and electrical.

If the electric juicer shows no signs of life, makes a lot of noise or vibrates, do not start disassembling it right away. The reason is often very commonplace. The main thing is to make a thorough external examination.

It is necessary to check the presence of power in the network, the reliability of the plug-to-socket connection and the integrity of the power cord. The latter, quite often fails due to bends or exposure to sharp objects. If damage is found on the cord, it must be replaced. As a last resort, splice repair is possible. In this case, special attention should be paid to the insulation of the wires.
The noise and vibration of the juicer are the result of improper assembly of the device or foreign objects falling into the drum.
The hum of the motor when the drum is standing indicates that the adapter coupling is overtightened. Usually the problem is corrected by loosening this part.

Other malfunctions will most likely require disassembly of the device.

The device of any electric juicer is not complicated. An obligatory attribute is an electric motor, which supplies the lion's share of malfunctions. This household appliance uses motors collector type and asynchronous... Each of them has its own disadvantages and advantages.

The former allow to reduce the size and weight of the product, but are not designed for long-term operation and require cooling, which is provided by the impellers mounted on the shaft. Asynchronous electric motors are more efficient, but take up more space and, accordingly, are distinguished by increased mass.

The motors mate with the centrifuge drum or rotate the auger. Depending on the type of juicer (centrifugal or screw), the connection is carried out by couplings or gears. These parts are usually made of plastic and are the cause of malfunctioning juicers. As a rule, manufacturers always provide a stock of these parts by including them with the juicer they sell.

The juicer motor is very finicky and fails when:

voltage drops in the network;
long-term work under heavy load;
moisture penetration into the engine compartment.

Damage can be caused by normal wear and tear.

For preliminary disassembly of the juicer, use the instructions attached to it. If one is not at hand, then you need to use logic.

Attention! You should never use excessive force when disassembling household appliances. This leads to the destruction of the case and mountings and is fraught with further problems. Manufacturers usually take care of customers and make this procedure as easy as possible.

After separating the remaining units from the engine compartment, they begin to disassemble it. A Phillips screwdriver is usually sufficient for this. After disassembling the compartment, the engine is freed from the couplings.

The speed switch and radio components included in the electric motor circuit are pre-checked. This operation is performed by the tester.

Even a superficial inspection of the motor can tell a lot about a malfunction:

Motor arcing and heat build-up are the result of abrasion or destruction of brushes (for collector motors). Replacing them will correct the situation.
Obstructed rotation of the armature shaft signals a failure or contamination of bearings... To remove them, you will need to disassemble the engine and use a puller. When assembling, pay special attention to the cleanliness of rubbing and rotating parts, as well as their lubrication. Regular cleaning and lubrication will help prevent this malfunction.
The smell of burnt insulation and blackening indicates burnt winding... Such a breakdown cannot be eliminated at home and requires the replacement of the entire unit.

Of all the points, only the last one is critical. All the rest are restored on their own, even with relative knowledge of electrical engineering.

Given the wide variety of juicers produced and produced today, it is difficult to describe all possible malfunctions of these units. Each of them may have their own specific case. But if you study the reviews of the owners of both domestic and foreign models, we can say that the main breakdowns are very similar.

Some useful information about the repair and maintenance of mechanical and electric juicers can be found in the video.

A juicer is a must-have equipment for all lovers of fresh juices. Autumn is harvest time. Fresh apples in the gardens of summer residents are pleasing to the eye. At first, it’s not clear how to deal with such volumes. Juicers come to the rescue. But, like any technique, sooner or later they break down. To make your life easier, you can repair a broken apparatus.Today there are many types of juicers, such as: Bosch (Bosch), Moulinex (Moulinex), Scarllet (Scarlet), Philips (Philips), SVA, Zhuravinka, Cameron (Cameron), First Austria (First Austria). The good news is that on the Internet you can find various videos on the topic of repairing juicers with your own hands.

Each juicer comes with instructions and an assembly diagram. But if you have been using the device for several years, the instructions could be lost. Even in this case, it will not be difficult to disassemble the device.

Having carried out repairs with your own hands, difficulties can arise only during the first disassembly.

The main thing is not to overdo it with efforts when disassembling. Otherwise, there is a risk of damage to the juicer body.

The juicer can be disassembled in several steps.

Make sure the power cord is unplugged.
We remove the product pusher from the loading compartment.
Remove the cover, having previously disconnected the mount.
Further, from under the lid, we take out the container that accumulates the already squeezed products.
We take out the chopper.
Disconnect the juice jug.

After disassembling the juicer body, then you need to remove the pulley. Usually, it is twisted off the shaft in the opposite direction from the working rotation.

To get to the bottom juicer motor, you need to:

Unscrew the screws securing the protective cover.
Remove engine guard, if fitted.
Remove the motor mount and remove it from the juicer housing.

There is an exception for auger juicers, which are similar in design to a meat grinder.

To disassemble them you need:

Remove the attachment.
Detach the receiving device with auger from the main body.
Remove the auger itself.
The engine itself can also be reached from below.

A breakdown of the juicer can be caused by both natural wear of materials and engine damage.

Remember that before disassembling the appliance, you should not just set the switch (lever) on the case to the Off position, but also completely disconnect the power cord from the power outlet.

The juicer motor can fail for several reasons:

Power supply voltage drops.
Due to prolonged operation and excessive stress on the juicer.
Due to liquid entering the juicer body.

If you do not have enough experience in repairing, it is better to seek help from a specialist.

Engine problems can be reported by:

Sparking and heating. This is the result of the abrasion of the brushes from the collector motors. The problem is solved by replacement.
The rotation of the armature shaft is impeded. The bearings should probably be replaced as they may have failed or become dirty. To prevent such damage, the juicer should be cleaned and the motor lubricated in good time.
If you smell burning and blackening is visible, the winding is most likely burnt out. This problem can be solved only by replacing the engine.

These are the main problems with juicers. And only one of them is serious. The first two can be solved quickly enough.

It would seem that everything has already been considered. How to disassemble the juicer is clear. What is the peculiarity of the Zhuravinka juicer? The peculiarity is that when you get to the engine compartment, you will not see any more mounts that would allow you to access the engine compartment.
Don't worry about this. All compartments are very tightly covered with a plastic disc, to which a grater-shredder was attached. It takes a lot of effort to remove it.

Independent repair of all types of juicers, including "Zhuravinka", is reduced to replacing broken parts, such as: wires, switch, bearings or electrical plug

To remove it, it is desirable:

Place the juicer on the floor and, holding it with your feet, pull the disc towards you.
If possible, you can ask someone to hold the case and carefully remove the disc yourself.

It is important to keep track of the effort you make so you don't break anything.

After removing the disc, four screws will be available to you, removing which you can get the engine and eliminate the cause of the breakdown. The Zhuravinka juicer is assembled tightly and quite simply. Unlike the First Austria juicer, which, according to numerous reviews, causes difficulties in disassembly, in disassembling the Zhuravinka juicer, additional efforts require only a disk that closes access to the engine.

Currently, Bosch juicers (bosch) with a capacity of 380w and 700w are gaining popularity on the market.
Assembling a Bosch juicer (bosch):

Bosch products continue to be associated with build quality, functionality and reliability

Insert the cake container into the engine block.
First insert the strainer insert with the spout into the hole in the motor block.
Now you need to insert the strainer. Check it for damage.
Next, you should install the cover, and press it so that it snaps into place. The switch must be in the Off position.
To trap the resulting foam, place a juice container with a large opening under the juicer drain.

To get juice, you need:

Place the juicer on a clean and smooth surface. Turn it on.
While the engine is running, put vegetables and fruits in the loading barrel. Use the pusher pushing down as gently as possible to avoid stress on the juicer motor.
Turn off the juicer only after all the juice has drained off.

Wait until the motor has come to a complete stop before opening the juicer. To open the lid of the juicer, you must first move the switch to the "open" position.

The pomace container must be emptied before the pomace rises to the top of the container, which should be grasped with your hands to remove it.

It is recommended to clean the strainer if:

The engine speed decreases.
The resulting juice became thicker.
The juicer vibrates significantly.

It is recommended to clean the cake container and strainer at the same time.

Whether it's spring, summer, autumn or winter, the body will always need juice. And it doesn't matter what kind of juicer you have: Bosch or Scarlett, Philips or Moulinex, the main thing is to understand the basic principles of assembly / disassembly of this device. So that, if necessary, replace the failed element. Let your juicer serve you long and productive. Make yourself and your loved ones happy every day.Why can't a person find the videos they want on Youtube? The thing is that a person cannot come up with something new and look for it.

Self-repair of a juicer, spare parts and attachments for a meat grinder.

Electric juicers are devices for making juice from fruits and vegetables by crushing them and then centrifuging them. These devices, which can be bought in domestic stores, can also be used for cutting and shredding vegetables and fruits. Depending on the structural elements and additional functions, the extractors can be divided into the first, second, third and higher categories. Depending on the category, the juicers are repaired accordingly.

- Elements that extend the functionality of juicers
- Electric brake.
- Element for grating raw vegetables, cutting and shredding them, mixing liquids, chopping fruits and vegetables.
- Lever that regulates the speed.
- Item for storing the power cord.
- An additional filter to improve the degree of juice purification.
- Classification of Russian devices

All domestic electric juicers can be divided by performance into models with low, medium and high performance (designations M, C and P, respectively). Additionally, the classification can take into account the method of removing the squeezed residues from the centrifuge. Low capacity devices are characterized by a manual removal method (MAP). Devices of average productivity can have semi-automatic or automatic removal of squeezed residues (SVSP and SVSA, respectively). Similarly for devices with increased performance - SVPP and SVPA, respectively.

Average construction

The design of a screw juicer for tomatoes or citrus fruits, which could be called the average for domestic buyers, belongs to the category of SVMR. The main element of this device is the body of the electric motor, in which the asynchronous motor is fastened with four screws. A platform is attached to the pins on the motor shaft, to the surface of which a grating disc and a mesh basket are screwed. These elements are screwed on with a plastic nut. Perforated plastic tape is located along the sides of the basket. The squeezer body is installed on the electric motor housing with its additional fixation. A window for loading fruits is provided in the body. On the housing of the electric drive there is a motor switch that drives the grating disc and the mesh basket in rotation.

How the device works

The electric extractor works according to the following principle. Fruits are placed in the loading window, which are fed to the blades of the grating disc using a pusher. After turning on the device, the process of crushing the fruits begins.Then the crushed fruits, under the action of centrifugal movement, are thrown onto the walls of the mesh basket, after which they fall into the tray through the holes of the perforated belt. Alternatively, the shredded material can be drained into prepared dishes.

Possible malfunctions

1. If the device does not turn on, it is worth checking the integrity and serviceability of the switch, cord and motor winding.

2. If the shaft does not rotate, but the motor hums, loosen and fasten the stator pack ties. Then the bearings are checked. Grease is added as needed.

3. If the device starts to vibrate strongly, you need to check the assembly of the parts, the reliability of the basket and grating disc on the platform shaft.

Is it convenient to use the extractor attachments?

The juicer attachment for the meat grinder is in great demand today. This is a screw nozzle, with which the meat grinder can turn into a juicer. How effective is this option? As the reviews show, efficiency is not always at its best, especially when working with apples. But there are also strengths. If for making juice you use small berries (strawberries, grapes), as well as herbs (dill, parsley), then the efficiency will be even greater than in the case of conventional squeezers. I must say right away that it is strongly not recommended to combine a regular meat grinder in which you turn meat with the functionality of a juicer. Still, meat is meat, and even after a good rinsing, putting fruits in the device and drinking the resulting juice without additional processing will not be very safe and hygienic, especially if a child drinks the juice. Therefore, the juicer attachment can only be used in meat grinders that have not been used and are not used for twisting meat products.

The principle of operation of the squeezer-grinder

If you still want to use the attachment as part of a clean meat grinder, you can get a powerful enough device with a manual or electric drive that will effectively crush the juice from the berries with a screw auger. At the outlet of the device there is a filter mesh or even a colander, the hole in which is intended for the exit of the cake. You twist the handle, rotate the auger and crush the berries, moving them with the screw towards the exit and simultaneously getting the squeezed juice. Another great advantage of structures of this type is the orientation towards them of domestic manufacturers. As a result, Russians get cheap and reliable devices of a familiar design, which their parents used to successfully. You will find spare parts for juicers of this type without any problems.

If you like freshly squeezed citrus juice containing the maximum amount of vitamins and nutrients, then you can easily turn the mixer into a citrus press using a special attachment sold in stores. This attachment allows you to work not only with large oranges and grapefruits, but also with lemons, limes and tangerines. The design of the nozzle is characterized by convenience and reliability. Install it on the drive of a conventional mixer with your own hands, turn on the speed you need, press half of the fruit against the ribbed cone and get juice flowing into the glass. Thanks to the plastic housing of the device, you can protect the drive from the ingress of juice, which is not only safe, but also hygienic. The built-in mesh will catch pieces of pulp and seeds, so your juice will be perfectly clean, without additional impurities.

If at the moment you do not know which juicer to buy so that you can later return it for repairs without any problems, choose popular manufacturers, such as: Zhuravinka, Rossoshanka, Bork (Bork), Moulinex (Moulinex), Juice Master, Zelmer, kenwood, bosch, scarlet, zhuravinka, philips and others.
