The invention relates to an antifreezing self-circulation environmental-friendly liquid-ring vacuum pump without continuous liquid replenishment, which comprises a pump body and an impeller. An air suction port is formed on the pump body, and a flange is arranged at the top of the pump body; a liquid storage tank is connected above the pump body in an airtight mode; an air vent is formed at the top of the liquid storage tank; and a liquid returning pipe is arranged on the lower part of the liquid storage tank and connected with a pump cavity liquid replenishing opening in the airtight mode. The antifreezing self-circulation environmental-friendly liquid-ring vacuum pump has high vacuum degree and large inspiratory flow and can add corresponding vacuum liquid according to the work environment and conveying media of the device. In addition, the liquid-ring vacuum pump has the characteristics of self-circulation vacuum liquid and no need of continuous liquid replenishment, enlarges the application range of the vacuum pump, and is suitable for outdoor operation without water sources at a low temperature in winter. Due to the adoption of a structural form of self-circulation and no leakage of the vacuum liquid, the vacuum pump is worthy of environmental-friendly equipment.
Description
technical field [0001] The invention relates to a liquid ring vacuum pump, in particular to a self-circulating and environment-friendly liquid ring vacuum pump which does not require continuous liquid replenishment and antifreeze. Background technique [0002] Water ring vacuum pump is one of the main equipment used to pump gas to create vacuum conditions. It is widely used in petroleum, chemical industry, electric power, electronics, metallurgy, environmental protection, food, pharmaceutical, synthetic fiber and other industries. [0003] The water ring vacuum pump rotates the impeller to drive water from the water ring vacuum pump inlet to send the gas to the outlet. During the working process, the work will generate heat, which will heat up the working circulation water, and at the same time, part of the water and gas will be discharged together. Therefore, the water ring vacuum pump must continuously replenish water to meet the working requirements of the pump. [0004]...
