1. When the dust collecting bucket and the filter of the industrial vacuum cleaner have a hard object impact sound, the industrial vacuum cleaner sucks in metal particles, metal blocks and relatively hard block objects, which may damage the filter element. At this time, as long as the machine is stopped, the internal foreign matter is taken out to prevent the hard object from scratching the filter material.
2. When the motor part has abnormal sound, the cause of the noise of the industrial vacuum cleaner may be that the impeller deformation is in contact with the outer casing, or the rotor of the motor is in contact with the stator, the motor bearing is damaged, etc. In this case, if not timely Handling may cause motor damage to be scrapped, or even cause fire due to frictional heat generation. In the event of such noise, stop the machine in time, disassemble the motor or the impeller cover, check for irregular friction and bumps at which position, and then calibrate the parts.
3. The suction of industrial vacuum cleaners is very large. If you choose too small or inappropriate vacuum cleaner or vacuum cleaner, it will not only affect the cleaning effect, but also make the equipment emit harsh or abnormal noise.
4. The motor of a general high-power industrial vacuum cleaner will emit a large noise, but industrial vacuum cleaners generally have a silencer or a muffler to silence the sound. If the noise of the industrial vacuum cleaner suddenly increases and there are no other fault factors, it may be that the noise reduction device has failed. It is only necessary to repair the noise reduction device in time.
5. The filtration system of the industrial vacuum cleaner has any blockage, such as air passages, dust suction ports, dust suction pipes, filters and air outlets. If there is dust or foreign matter blocking, the vacuum cleaner will make an unusual dull sound. If it is not ventilated in time, it will cause poor heat dissipation, heat generation and even burning of the internal motor of the equipment. Therefore, once the situation is discovered, it is necessary to stop the inspection and eliminate the blockage.
