Video Disassembly / Assembly of the vacuum cleaner “Buran” Disassembly / assembly of the vacuum cleaner “Buran” of altevaa TV channel
Once upon a time, in times that our mothers and fathers remember well, the variety of household assistants was considered something very unusual and unusual. And this applies not only to irons, stoves, refrigerators and other household appliances, but also vacuum cleaners. Judge for yourself. If today numerous manufacturers offer as many as four types of vacuum cleaners, such as: dry cleaning machines, washing machines, with aquafilters, and even robotic units, then in the country of “soviets” the designs of vacuum cleaners were quite uncomplicated and differed only in that they were either manual or universal floor. But, despite this, at one time they were all in great demand and were considered a truly valuable acquisition that could emphasize the status of a family.
Of course, today, having found a similar unit in an old barn in the country, many will smile and say: “And how did people live without modern, light and very efficient household appliances?”. However, it should be noted that household appliances of the Soviet assembly, such as, for example, vacuum cleaner Buran functioned for decades without any repairs, and many that have survived to this day work quite well. It would seem that bulky, clumsy and very noisy in operation, thanks to their simple design, if they needed repair, then very little, always serving their owners regularly.

In fact, analogues of vacuum cleaners were invented even before the revolution. So, the first dust collectors were put into production in the thirties and were considered a "breakthrough" in the world of household appliances. But they became available to the "popular masses" only from 1952. The first unit that Soviet citizens met was the Pioneer vacuum cleaner. Its power was only 120 watts. Of the equipment, only a brush made of horsehair was attached to it. There was also a dust collector, a filter bag that was attached to the handle. The engine of the device was cooled thanks to the holes in the case. The first household vacuum cleaner was heavy, clumsy, and certainly not as efficient as current models.
Today everyone knows that the best vacuum cleaner model is the one that most effectively sucks and holds dust. At
This information that dust, in addition to soil particles, contains pollen, bacteria, animal hair, dust mites, dead particles of human epithelium and much more, is not a secret. But during the period of popularity of vacuum cleaners Buran, Whirlwind, Veterok, etc., few people thought about such things, since they all more or less coped with the task (cleaning up small debris), and their “deficit” in the household appliances market made the purchase of such an apparatus a significant event for most housewives of that time. So, in order to buy a Buran vacuum cleaner, it was not enough to collect the required amount: it still needed to be “gotten”.Buran vacuum cleaners were real favorites and a dream of women. Their design was copied from Western analogues produced by Electrolux.Such devices were used not only for cleaning rooms, but also, at the suggestion of "craftsmen" for catching mosquitoes and even for whitewashing ceilings and much more.
The reliability of Buran vacuum cleaners was undeniable: Soviet models were produced with a quality mark and passed inspection by the Quality Control Department. All parts of such structures were made of durable metal, and the apparatus was assembled manually. Of course, the units were quite heavy and very noisy. But at the same time, only a short circuit in the mains, a burst hose, or a fall from a great height could disable them.
However, despite their demand, even in the years of "glory" vacuum cleaners were produced in limited quantities. History knows examples when 800 thousand pieces were produced in a year, which, in comparison with current figures, is just fun.
As mentioned earlier, the design of Soviet-assembled vacuum cleaners was rather primitive. Therefore, the principle of operation also did not differ in particular complexity. The electric motor of the vacuum cleaner, connected to the mains, began to rotate at a speed of 12 thousand to 18 thousand rpm. a fan rotated with it, the purpose of which was to create a strong vacuum of air inside the vacuum cleaner. The end result of this action was the formation of an air flow, with which particles of debris and dust were sucked into the unit. At the same time, the intake air flows around the lower part of the engine and, being freed from dust and debris, passes through a fabric filter and then through the fan out.
For example, the Buran 5M vacuum cleaner is a household model for dry cleaning. With its help, it was possible to carry out such operations as:
- room cleaning;
- carpet cleaning;
- whitewashing the walls.
The model belongs to vortex vacuum cleaners, in which the intake air swirls at the inlet. At the same time, large particles of dust and small debris settle in the lower part of the housing without clogging the filter. In vacuum cleaners of this type, the electric motor is located vertically, which is why the Buran has a body in the form of a bowl made of metal.
As mentioned earlier, the design of the unit, in comparison with modern models, is so simple that the technical characteristics of the snowstorm vacuum cleaner fit in several lines. The power consumption of the device is 600 W; dust-cleaning capacity on the floor - 96, on the carpet - 88. The weight of the vacuum cleaner is 7 kg.
The main working part of the vacuum cleaner is the air suction unit, which consists of a fan driven by an electric motor. In addition to the main details, the design is also equipped with a flexible corrugated hose and a set of special nozzles. The design contains two fabric filters, which are made of calico and velveteen, which need to be cleaned every time after using the vacuum cleaner.
Despite the simplicity of the design, as well as the fact that Soviet models are practically “indestructible” and the repair of a snowstorm vacuum cleaner is rarely needed, there are a number of simple rules, following which you can extend the life of the device for an infinitely long time, and if you wish, you can use it and today.
- Vacuum cleaner filters should be cleaned of dust every time after using the unit.
- Filters in Buran made of velveteen cannot be washed.
- When installing the filter after cleaning at the workplace, make sure that the surface of the filter that faces the electric motor is clean, because the dust, falling on the working motor, again scatters through the air.
- If the vacuum cleaner is used for a long time, it is important to know that after every hour it needs a break of 10-15 minutes (to cool the motor).
- The full wear of the motor carbon brushes occurs after 300 hours of operation, after which they should be replaced.
- When replacing the brushes, it is also recommended to wipe the motor manifold with a cloth soaked in gasoline.
- Such a simple job as replacing brushes can be done independently, but if a more serious breakdown occurs, the unit should be restored to working capacity in a repair shop.
Buran vacuum cleaners today are called by many a rarity. Compared to today's lightweight and comfortable models with a wide variety of built-in functions, such a device, of course, looks awkward. But, meanwhile, the unit feels great, for example, in the country, and copes well with minimal tasks. And if you are suddenly overcome by curiosity, or an urgent need to test the "old man" (clean up the premises with his help) - this information is for you:
- debris often gets stuck inside the corrugated hose, so before using the unit for its intended purpose, check the device by attaching it to the inlet flange;
- so that during the operation of the vacuum cleaner dust does not enter the room, be sure to insert the end of the hose into the inlet of the device;
- for operation, the Buran vacuum cleaner needs power supply from an AC voltage of 220 V;
- the power consumption of the vacuum cleaner is 140-600 W;
- the vacuum cleaner will take up less space if its case is designed in the form of a pouffe, which can be used to decorate any living space.
The Buran trademark, which once produced famous vacuum cleaners, still functions to this day. And, although the production of household vacuum cleaners has been stopped for today, the company's products are quite well known. The main activity of the brand at the moment is the development and production of tools for domestic use, as well as several types of goods for professional use. So, among the manufactured products, such tools as punchers, drills, grinders, screwdrivers, jigsaws, circular saws and much more are in special demand among consumers. At the same time, as before, the main criteria in production are the use of the best materials and constant quality control. At the moment, Buran power tools are made from the best metal alloys, which makes them reliable helpers in everyday life. The range of the company is constantly expanding and is the best option that the modern domestic market can offer, both for amateurs and professionals.
Production of TM Buran products is carried out in Chelyabinsk. At the same time, each power tool is provided with a quality guarantee for a period of 12 months, as well as post-warranty repair and maintenance. The company's products are quite well known for their quality in the expanses of the post-Soviet space, so there are branches and stores of this brand in many cities.
As for the “legendary” Buran vacuum cleaner, today, in the light of various new models, it can only be of value among lovers of antiquity and all kinds of Soviet-made products. Although, there are many models that are still in working condition. With regards to spare parts, you can’t find them in specialized stores, but you can easily find what you want on the Internet.

The Buran trademark, which once produced famous vacuum cleaners, still functions to this day. And, although the production of household vacuum cleaners has been stopped for today, the company's products are quite well known. The main activity of the brand at the moment is the development and production of tools for domestic use, as well as several types of goods for professional use.

As for the “legendary” Buran vacuum cleaner, today, in the light of various new models, it can only be of value among lovers of antiquity and all kinds of Soviet-made products. Although, there are many models that are still in working condition. With regards to spare parts, you can’t find them in specialized stores, but you can easily find what you want on the Internet.
When repairing a vacuum cleaner, you can replace the motor, the armature in the motor and the carbon brushes. For example, consider the repair of the Buran vacuum cleaner. First you need to disassemble the vacuum cleaner.To do this, open the hinged locks and remove the dust container. Remove the fabric filter with sealing ring. Unscrew the 4 screws connecting the upper housing to the intermediate one.
Engine replacement should be done like this. Remove fan unit with motor. Remove the lower cup and unscrew the nut securing the turbines to the armature shaft, after securing the armature from turning. Remove the washers, lower impeller, adjusting washer and bushing from the armature shaft. Remove the upper cup, remove the adjusting washer, upper impeller and bushing from the armature shaft. Replace the motor with a new one and assemble the vacuum cleaner in reverse order.
When replacing the armature, it is necessary to separate the motor from the fan unit as when replacing the motor. Unscrew the two caps from the brush holders and remove the carbon brushes. Loosen the three screws securing the endshield to the motor housing. Remove the clamps of the stator coil leads from the brush holders, unsolder the other two stator coil leads from the capacitors and remove the end shield. Remove the washer with the stuffing box from the bearing shield seat. Loosen the two screws and remove the capacitor unit from the endshield. Unscrew the two screws from the motor housing from the side of the free end of the armature shaft.
Remove the armature with ball bearings from the stator. Using a puller, remove the bearing and washer from the armature shaft (from the side of the collector), as well as the thrust plate (from the side of the free end of the shaft). If necessary, replace the seal or bearing. Install a new anchor and assemble the motor, and then the vacuum cleaner in reverse order. When installing the endshield on the motor housing, make sure that the marks on the endshield and on the motor housing match.
In order to replace the carbon brushes, you need to open the locks on the body, remove the dust collector and filter. Unscrew the 4 screws connecting the upper and intermediate housings. Unscrew the caps of the brush holders and remove the carbon brushes. Put new brushes and assemble the vacuum cleaner.
As we have already seen, there are a lot of brands of washing machines. But for example, let's take the CM-1 "Baby" washing machine. The unit is a plastic tank with a tight lid, on which an electric motor is mounted, placed in a protective plastic casing. If the machine does not work when plugged in, then first you need to make sure that the cord is working. It is either repaired or replaced with a new one. If a malfunction is found in the machine itself, it must first be disassembled, having previously familiarized itself with some of the features of the apparatus (Fig. 80).
Rice. 80. The device of the washing machine "Baby":
1 - seal; 2 - activator; 3, 18, 19, 43 - gaskets; 4 - spring; 5 - cuff; 6 - body of the activator; 7 - activator bushing; 8 - tank cover; 9 - tank; 10 - flange; 11, 17, 22, 29 - screws; 12 - flange; 13, 42 - plastic nuts; 14 - rubber bushing; 15 - electric motor; 16, 24 - half of the casing; 20, 23, 44 - bushings; 21 - rubber stopper; 25 - gasket; 26, 28, 32 - clamps; 27 - capacitor; 30 - nut; 31 - thermal relay; 33 - washer; 34 — hose-tube; 35 - tip; 36 - drain tube; 37 - nozzle; 38 - plastic stopper; 39 - tongs; 40, 41 - rubber rings
Disassembly of the casing should be carried out, observing some rules. The action plan should be like this. First you need to remove the lid from the tank. Then, on the back of the casing, find a hole masked by a decorative plug. This plug must be removed, and then rotate the activator so that the holes in the casing and the impeller of the electric motor are aligned (Fig. 81). Take a screwdriver with a long shaft and thread it into both holes. When the screwdriver hits the rotor of the electric motor, it should be locked by holding it with one hand. With the second hand, you need to turn the activator, rotating it effortlessly in both directions.
Sometimes there is a malfunction of this kind: the machine buzzes when turned on, but the activator remains motionless. After a few seconds of this operation, the thermal relay switches off the motor.The reason may be the simplest: threads are wound on the shaft, pieces of fabric come off, or small buttons, coins, etc. are stuck. To eliminate this malfunction, you need to clean the shaft and then twist it with light movements. If the rotation is smooth, there is no locking, then the activator can be assembled in the reverse order. After that, you need to try to start the machine. Usually no further disassembly is required.
To further dismantle the washing machine, you will need a special tool that can be made at home. To do this, you need to take a steel bar with a diameter of 15-18 mm and two screws having a diameter equal to the diameter of the holes in the activator body. Make two holes in the rod, screw the screws into them. For this purpose, a piece of pipe with a diameter of half an inch is also suitable. It also needs to drill two holes for the screws. Fasten the screws from the outside with nuts. Using the tool described above, remove the activator housing, separate the electrically driven casing from the machine tank. Remove the six cover screws and remove the O-ring flange assembly (fig. 82).
Rice. 83. Disassembly of the unit with electrical equipment:
1, 8 - screws; 2 - flange; 3 - sleeve; 4, 5 - spacers; 6, 9 - semi-body; 7, 15 - seal; 10 - curly nut; 11 - cork; 12 - electric motor; 13 - capacitor; 14 - bracket; 16 - thermal relay
After removing the flange assembly, it is necessary to dismantle the sleeve with a set of spacers from the shaft. Remove the decorative plugs from the casing, unscrew the screws connecting the casing half-shells, and remove the curly nuts (Fig. 83). After that, separate the half-shells, remove the rubber seals. Now you can start repairing the electrical equipment of the machine.
When the machine is plugged in, but no buzz is heard, then the contact is probably broken, the cord inside the casing is broken, the installation wires are damaged, or there are problems in the motor windings. In addition, the time relay or thermal relay fails.
The entire electrical circuit must be checked with a probe or ohmmeter. If the contacts are loosened, they must be tightened; if moisture gets on them and rust occurs, the contacts are cleaned, dried and the screws are tightened again. If necessary, replace screws that have stripped threads.
Sometimes it becomes necessary to replace the switch. First unscrew the plastic cap and metal nut, then remove the spring washer and place the switch inside the housing. The mounting wires are disconnected from the switch terminals. If the contacts burn, they are cleaned, wiped with a rag soaked in kerosene, dried and assembled in the casing in reverse order.
Since the most common refrigerators in everyday life are compression ones, for example, consider the repair of the Polus compression refrigerator.
Door replacement. Loosen the three screws securing the top hinge of the door to the cabinet body. Remove the door from the top and bottom hinge pin. Install the new door with the bottom bearing bushing hole on the bottom hinge pin. Insert the top hinge pin into the hole in the top support bushing. Adjust the tight fit of the door to the cabinet by moving the top hinge. The door should turn easily. After testing, tighten the screws.
Door panel replacement. Remove door. Unscrew the 30 screws securing the door panel. Remove panel with slats and rubber seal. Remove the seal and strips from the panel. Install the planks on the new panel and drill holes in the panel along the holes in the planks. Put the seal on the panel and place it as an assembly on the door body. Punch holes in the seal, aligning the holes of the panel and the door body, fix the panel with screws. Mount the assembled door.
Replacing the rubber door seal. Remove the door assembly, panel assembly and rubber seal from the panel. Put a new seal on the panel. Place the panel assembly on the door body.Make punctures in the seal along the holes of the slats and the panel and tighten the screws that secure the panel. The seal must lie flat and not kink. Install the door on the refrigerator and check the tightness of the door to the cabinet.
Lock replacement. Remove the door and door panel assembly. Unscrew the screw securing the lock body to the door body plate. Rotate the lock body by 90° and remove it from the groove in the bar. Install the body of the new lock into the groove of the door strip, rotate it by 90° and align the holes in the lock with the holes in the strip. Fasten the lock body with a screw, having previously put a spring washer on the screw. Place the panel on the door body. Install the door on the refrigerator and check the operation of the lock and the tightness of the door.
Refrigeration unit replacement. Unscrew the two screws securing the capacitor to the cabinet brackets. Carefully tilt the condenser so that you have access to the outer flange. Unscrew the 12 screws securing the outer flange to the rear wall of the refrigerator. Release the suction tube and electric cable from the slot of the sealing sleeve and remove the sleeve. Remove the thermal insulation through the rear wall window. Bend 8 brackets of the inner flange from the edge of the window and remove the flange from the window in the rear wall of the cabinet. Loosen the two screws securing the evaporator. Remove the two screws securing the bellows tube holder and bellows tube to the evaporator. Release the evaporator pins from the holes in the brackets. Loosen the four bolts, then unscrew while supporting the refrigeration unit and remove it.
Insert two pins of the evaporator into the holes of the brackets and fix the evaporator with two screws to the threaded bushings, placing washers under the screw heads. Align the holes of the refrigeration unit bracket with the holes of the racks of the rear wall of the cabinet and screw in four bolts, placing spring and plain washers under the bolt heads. From the side of the window, fasten the tube of the thermoregulator bellows to the evaporator with two screws, placing the screw heads on the inner wall of the evaporator. Put a sealing sleeve on the tube of the refrigeration unit going to the evaporator. Install the inner flange into the window of the rear wall from the inside and bend 8 brackets onto the edge of the window of the inner cabinet from the outside. Lay thermal insulation in the window of the rear wall of the cabinet. Insert the sealing sleeve into the socket of the outer flange, insert the suction tube and the wires of the refrigeration unit into the slot of the sleeve.
After that, align the holes of the outer flange with the holes of the rear wall of the cabinet and fix the flange with screws. Carefully guide the condenser to the two cabinet wall brackets so that they are positioned between the condenser coil tubes. Place the mounting plates on the condenser grille and, aligning the holes of the mounting plates with the holes in the brackets, fix the condenser in two places with screws. When installing the refrigeration unit, the condenser must be located evenly, without distortions; tubes must not be deformed.
