Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space. The air extracted by the vacuum pump often contains a large amount of particulate matter. If these particulate matter enters the vacuum pump without filtering, the service life of the vacuum pump will be shortened. Therefore, it is necessary to invent an anti-clogging filter device for an embedded liquid ring vacuum pump.
