During the daily use of the dust collector, special personnel are required to inspect and clean the dust to ensure the normal operation and use of the dust collector. Before use, check whether the working environment voltage is normal, whether the indicator light is working normally, keep the power supply grounded, close all the locks, and check whether the filter bag is damaged. Dry-type dust collectors should not absorb high humidity or deliquescent media, and cannot absorb media with fire; the vacuum tube should not be bent and used, and there should be no damage such as cuts or burns; the collection of dust in the drawer should be timely Be sure to turn off the machine during cleaning to prevent unsafe accidents and secondary dust pollution; If the filter bag is worn after long-term use, it should be replaced in time to reduce unnecessary losses; severe impact will cause certain parts Deformation may lead to inadequate sealing, which will affect the suction and dust removal effect, so it should be avoided as much as possible; dust collectors that absorb special gases must be checked frequently to prevent leakage and cause unsafe accidents. The dust collector is generally a fixed device. The ordinary single-unit dust collector should be placed indoors, and the exhaust pipe can be changed to the outdoors. If it must be installed outdoors, a protective cover can be built or the electric control can be separated from the machine. Dust removal units are generally placed outdoors, and attention should be paid to the impact on the surrounding environment and safety protection.
