Abstract

The invention discloses a water ring vacuum pump, and belongs to the technical field of liquid pumps. The water ring vacuum pump comprises a pump body, wherein a water ring rotor is rotatably mounted in the pump body; an air inlet and an air outlet are formed in the top of the pump body; a working liquid inlet and a working liquid outlet are formed in one side of the pump body; the working liquid inlet is connected with an impurity removing box; a closed impurity removing cavity is formed in the impurity removing box; a liquid inlet and a liquid outlet which communicate with the impurity removing cavity are formed in the impurity removing box; the liquid outlet is connected with the working liquid inlet; a plurality of hollow tubes which penetrate through the impurity removing cavity are arranged on the impurity removing box; two ends of each hollow tube are open but do not communicate with the impurity removing cavity; and a permanent magnet is inserted in each hollow tube. The water ring vacuum pump has good industrial application prospect and industrial potential productivity.

Description

technical field [0001] The invention relates to a pump, more particularly to a water ring vacuum pump, belonging to the technical field of liquid pumps. Background technique [0002] The water ring vacuum pump realizes suction, compression and exhaust by changing the volume of the pump chamber. Therefore, the water ring vacuum pump belongs to the variable capacity vacuum pump. [0003] Due to the excellent performance of water ring vacuum pumps, water ring vacuum pumps are widely used in many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing. At the same time, due to the rapid development of vacuum application technology, the water ring vacuum pump has been paid attention to in terms of vacuuming. Because the gas compression in the water ring vacuum pump is isothermal, it can pump out flammable and explosive gases. Extract dust and water-containing g...
