The invention discloses a water ring vacuum pump. The water ring vacuum pump comprises a base, a pump body, side covers, a shaft, an impeller and a water tank, wherein the pump body is fixed to the base; the side covers are arranged on the two sides of the lower portion of the pump body; the shaft is arranged inside the pump body; one end of the shaft extends out of the pump body; an abrasion-resistant gasket is arranged at the position where the pump body and the tail end of the shaft make contact; the impeller is arranged below the shaft; an opening is formed in the top end of the pump body; the water tank is installed in the opening; a partition board is arranged in the middle of the water tank; a gas-water separation device is arranged below the partition board; a water inlet pipeline is arranged between the partition board and the gas-water separation device; a through hole is formed in the water inlet pipeline; a control valve is arranged at the head end of the water inlet pipeline. The water ring vacuum pump has the advantages that the structural design is reasonable, use is convenient, operation is rapid and convenient, maintenance is convenient, the gas-water separation device can ensure stability and reliability in the operation process of the pump body, and the service life is prolonged greatly.
Description
technical field [0001] The invention relates to a vacuum pump, in particular to a water ring vacuum pump. Background technique [0002] Water ring pumps were originally used as self-priming pumps, and then gradually used in many industrial sectors such as petroleum, chemical industry, machinery, mining, light industry, medicine and food. In many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture resurgence and vacuum degassing, etc., water ring pumps are widely used. Due to the rapid development of vacuum application technology, water ring pumps have been paid attention to in obtaining rough vacuum. Because the gas compression in the water ring pump is isothermal, it can pump out flammable and explosive gases, and also can pump out dusty and water-containing gases. Therefore, the application of water ring pumps is increasing day by day. However, the existing water ...
