At all times to support the purity, people have used various devices and tools. With the advent of electricity availability of effective and easy to use assistant in this case. Some of them are cleaners. They come in, both household and industrial.
Vacuum cleaners are divided on the basis of the work and purpose. So, there are washing vacuum cleaners, which in addition to cleaning the dust can do wet cleaning. They have a lot of tips, the use of which extends the capabilities of the vacuum cleaner.
By design, vacuum cleaners can be pylesborochnym bag with aquafiltering and cyclone system - when the trash is compacted into briquettes.
On the example you can see how a simple vacuum cleaner with a dust bag. The main element in its structure type is a collector motor with impeller fitted on its axis. When the impeller starts rotating, it creates a flow of air that moves from the working of the hose through the bag and out into the room.
Passing through the cloth bag, the dust is delayed, as already relatively clean air passing through the foam filter, the cleaner exits through the grille. Although this method of collecting dust is not the most efficient, but it is considered to be very simple. Therefore a vacuum cleaner with a filter cleaning are inexpensive and are very popular. Their main drawback is that dust tapping out of the bag is time consuming and requires going outside. However, for many it is not a very big problem.
Therefore, this article will focus on this type of vacuum cleaner and the possible causes of its failure.
For example is a vacuum cleaner repair MACH4 German manufacturer. According to the design and operating principle, he is not much different from other companies vehicles. Therefore, this guide to the diagnosis and repair is applicable to many vacuum cleaners such performance.
So, let's failure symptoms.
Vacuum cleaner stopped working without any reason. No power surges or falls, no smoke and cod, nothing happened.
Just one day, when incorporated into the network he did not show any signs of life.
Manipulating any results control buttons to no avail.
AC mains voltage present. It became clear that the dismantling of the vacuum cleaner can not be avoided.
First you need to determine where the mounting screws on the top cover.
This vacuum cleaner screws are hidden under the dust collector panel. To remove this panel, it is necessary to lift the latch and push it forward (Figure 4 and 5).
When the cover is disengaged and withdrawn. Under it there are two screws (Figure 6) to be unscrewed. For this fit Phillips screwdriver.
Remove the screw, remove the lid.
After removing it, you can see the main components of the vacuum cleaner (see. figure 8). Among them: the electric motor, power control board connectors, controls and coil cord.
On photo 9 - connector scheme. Choosing a connector, from which wires go to the network coil (Figure 10).
You need to remove it to check the integrity of the cord. Thus, you can see if the mains voltage on the vacuum cleaner comes.
Since the cord is often subjected to mechanical stress (twisting and stretching), it is very vulnerable and often, one of his breaks lived under the outer insulation.
It can be used to check the connection to any device that can do it. For example, an ohmmeter, multimeter or voltage pointer.
Connecting one end of the device with one of the terminals on the connector, and the other with a pin on the plug (Figure 11).
If the connection device not shown, we move the instrument probe to the other is carried on the connector. If one of the provisions of the chain is present, it means that one wire in the cable is safe and it is good.
Now, a second check is carried out. We move the probe instrument to another pin on the power plug.
The other end of the unit, just as in the first case alternately connect with the terminals on the connector.
The device in any of the findings showed the chain, which means that there was a breakage of the wires in the cord. Hence, there is no voltage on the vacuum cleaner and the refusal of his work.
Now that we know the cause of failure, you need to find where the open and remove it.
To do this, remove the coil and take it apart.
This may prevent the wires passing over the coils. Therefore, disable connector with these wires.
Now that does not interfere, remove the drum by lifting it up (Figure 14).
When it is removed, place it on its side and unscrew the screws in the center and on the edge.
Then, remove the protective cover of the coil. On the reverse side of the cover two annular fixed contacts are arranged.
When the coil is unwound, the moving contacts slide on the ring, so that the supply voltage falls further into the vacuum cleaner units.
On examination, it was found that one of the wires "popped out" of the clamp on the current collector (Figure 16).
This could be due to shaking and the wire tension when the drum rotates.
Now you can check that the cord is really safe.
Just as mentioned above, alternately connect the pins on the plug with the wires on the cable end. If the whole cable, the device should show a chain on two wires.
In the picture 17 that is the case. This once again confirms that the problem is a relief measure in the clamp and disconnect the wires from it.
To this no longer happens, extend the cable by adding to it a small piece of copper wire.
This will prevent the stretch and give the opportunity not only to have and hold down the mine, but also to turn it into a loop. Such a connection provides good contact and prevent slipping repeated.
Additional wire connects the main by stranding (Figure 19). twisting can solder, if desired.
This will provide a more reliable contact, but this is optional. The main thing that both conductors in place of stranding, have been well cleaned and tightened with pliers.
Next, isolate the conductive PVC tape.
The loop on the end of a wire previously inserted otkruchenny screw clamp. Then insert it into contact thread and tighten (figures 21 and 22).
Now that the wires in place, for good contact, we clean sandpaper fixed ring contacts.
You can rub and slip rings, but this vacuum cleaner they are quite clean.
After cleaning, wipe the contacts must be cotton wool soaked in alcohol or cologne. This action removes the metal chips, which may result in the closure between the two contacts.
Next, install the drum cover and fasten it with the screws (Fig. 24).
The next phase - installation of the drum into the vacuum cleaner.
For this threading cord with a plug to the outlet, and failure to insert the drum (Figure 25).
Set the connectors on the board, according to the scheme (Figure 26).
Before putting on the protective cover on the handle stem combine power regulator with a slit on the resistor.
Now carefully put on the cover, connecting all of the grooves. Hold it with the screws and install the dust receptacle panel.
Check how the drum mechanism, if it twists the cord through.
Also, by including the appliance in the network, test the power button and power regulator.
If it works, it can be assumed that the repair was successful!
Finally, a few suggestions:
- Firstly, unwinding the cord to keep the drum brake button down.
- Second, do not increase the length of the cable on the limit mark on it.
- Third, do not put the vacuum cleaner upright when untwisted cord.
These simple guidelines will increase the long "life" of a vacuum cleaner.
