Dust removal and filtration method of oil seal vacuum pump Some vacuum processes will produce a lot of dust. If the dust enters the oil seal vacuum pump with the extracted gas, it will accelerate the wear of the parts in the pump cavity like abrasive, cause wear and damage to the pump rotor and pump cavity, block the oil circuit or make the pump unable to run. If the dust enters the vacuum valve, it will make the seal invalid and leak, so the dust prevention and filtering has been completed The use of dust filters in vacuum systems must be critical for increasing the lifetime of the dust system. When the amount of dust is small, it can be filtered by the pump oil filtering system, but when the dust amount is large, the dust collector must be used to prevent the damage of the vacuum pump and ensure the normal operation of the vacuum pump.
