Abstract
Description
technical field
[0001] The invention relates to a water ring vacuum pump disc pump device. Background technique
[0002] The water ring vacuum pump is one of the most important equipment in the coal mine gas drainage system, and its working performance directly affects the mine gas drainage effect and safe and efficient production.
[0003] However, after running for a period of time, due to the corrosion of the circulating water quality, the inner surface of the pump casing and the impeller of the water ring vacuum pump will be covered by a hard rust layer. In the event of a small card pump accident, the resistance in the pump body becomes larger at the same time, and there is a danger of twisting the pump shaft and burning the motor. With the increase of production capacity and depth of coal mines, gas control becomes more and more difficult, and the requirements for the capacity and operation stability of water ring vacuum pumps are also getting higher and higher.
