High-power industrial vacuum cleaners are generally used in production plants, workshops, engineering constructions, etc., but they may be used in different industries and the site conditions are very different.
However, in the use of industrial vacuum cleaners, except for the different models equipped on-site, most vacuum cleaners have the same working principle and even the same structure. Therefore, in order to clearly grasp the maintenance and repair methods of the high-power industrial vacuum cleaner used in the workshop, we must first understand the working principle and structure of the industrial vacuum cleaner.
The structure of high-power industrial vacuum cleaners is different from that of household vacuum cleaners and commercial wet and dry vacuum cleaners. Generally, it uses a 380V power supply. It mainly includes a high-pressure air pump, dust collection bucket, filter system, frame body, and electrical For the control part, the models with higher configuration are also equipped with negative pressure gauge, dust vibration system, filter cleaning system and so on.
Regardless of the structure and composition, the basic working principle of the 380V industrial vacuum cleaner is the same, that is: after the vacuum pump is started, the high-speed rotation of the impeller generates high negative pressure; the substance to be sucked passes through the suction head (suction grille, flat suction nozzle) Or round brush, etc.), and then enter the collection bucket that is already in a high negative pressure state through the vacuum cleaner tube. Since the source of vacuum negative pressure is a vacuum fan, some lighter dust will travel in the direction of the fan. During the process, the filter system is encountered. Under the action of negative pressure, the light dust is adsorbed on the surface of the filter. After the dust is blocked, the clean air passes through the filter, enters the fan impeller, and is discharged from the air outlet.
After understanding the principle and structure of industrial vacuum cleaners and the filter materials of industrial vacuum cleaners, you can know that the problem with vacuum cleaners is dust filtration. As long as the following two points of maintenance are done in normal use, you can basically avoid the phenomenon of poor use of the vacuum cleaner.
1. Frequently check whether the vacuum pipe is unblocked and unblocked during use;
2. The filter must be cleaned up before each use and cleaned up after use. Check the filter regularly. Is there any damage? Is it aging that it has not reached the original filter accuracy and needs to be replaced?
If the vacuum cleaner fails, for example, the suction power suddenly becomes very small while it is in use, how should it be repaired and repaired?
The troubleshooting steps for industrial vacuum cleaners are as follows:
1. In the state of starting up and running, carefully listen to whether the sound of the fan running suddenly becomes louder or dull, or there are other abnormal noises alive? If the sound becomes louder, it may be that the filter is clogged or the straw is clogged.
2. If the industrial vacuum cleaner is equipped with a negative pressure gauge, observe whether the negative pressure value exceeds the normal value?
3. Check if the filter is clogged, and clean it in time if it is clogged?
4. Check whether the dust bucket is full?
5. After the above investigation, if the suction power is still not strong, check whether there is a problem with the vacuum cleaner hose. The method is: unplug the hose from the vacuum cleaner and test the suction power at the suction port by hand; then connect the hose to On the machine, test the suction power of the suction port at the other end of the hose by hand. If the suction power is very different, it may be because the soft management has blocked a large piece of garbage or the hose is damaged.
Generally speaking, high-power industrial vacuum cleaners are industrial vacuum cleaners with a very low failure rate, with stable performance, and the maintenance and repair of vacuum cleaners are also very simple.
