Abstract

The invention discloses a backwater system and a backwater method of a liquid ring vacuum pump. The backwater system comprises a vacuum pump body (1) and an external gas-water separator (8). The backwater system is characterized in that the other end of the gas-water separator (8) is connected with a heat exchanger (9), a booster pump (10) is connected to the tail of the heat exchanger (9), a plurality of pipelines are connected to the booster pump (10) and are connected with a backwater inlet (10.1) in the cylinder wall of the vacuum pump body (1), a flow monitoring device (11) is connected to each pipeline, and a pressure monitoring device (12) is connected to the pipeline behind the booster pump (10). The defect that cavitation easily occurs in a cavity due to the limit to the temperature and vapor pressure of working liquid in prior art is overcome, and the backwater system has the advantages that the working liquid is effectively supplemented, and the temperature of a liquid ring is reduced.

Description

technical field [0001] The invention relates to the research fields of energy and chemical technology, and more specifically relates to a water return system and a water return method of a liquid ring vacuum pump. Background technique [0002] Liquid ring vacuum pumps are mainly used in the formation of rough vacuum. Because of their advantages of close to isothermal compression, insensitivity to dust, and the inhaled gas can entrain liquid or a large amount of water vapor, it is widely used in the power industry. Both the vacuum stage and the vacuum maintenance stage are completed using vacuum pumps and complete sets of units. The liquid ring vacuum pump is composed of a low-speed motor, a steam-water separator, a working fluid cooler, a pneumatic control system, a high and low water level regulator, relevant connecting pipes, valves and electrical control equipment inside the pump unit, and its function is to establish a vacuum when the steam turbine unit starts. And pump...
