AI Technical Summary
Existing vacuum pump pre-filtration systems are unable to effectively intercept fine impurities in the food industry, leading to accelerated wear of the vacuum pump, reduced pumping efficiency, increased maintenance costs and downtime, and impacting production efficiency and product quality.
A self-cleaning vacuum pump pre-filtration system was designed, including a coarse filter tank assembly and a liquid storage tank assembly. It is equipped with a liquid cleaning solenoid valve and a gas backflushing solenoid valve to achieve automatic cleaning and gas-liquid separation. Combined with the frame assembly, it is automatically controlled to ensure stable system operation.
It achieves efficient filtration of impurities, reduces maintenance costs and downtime, ensures the continuity and stability of the production process, and improves the service life and production efficiency of vacuum pumps.
