‌1. Overview

ZPSQ series wind pump automatic drainage device is mainly used for automatic control of wind pump in coal mine. Because the mine wind pump is powered by air source, which excludes the safety hazard caused by electricity, it is more and more favored by the majority of coal mine workers. But the wind pump in the use of the process, the need to set up a person to control the wind pump, not only take up a lot of manpower, and human factors, poor reliability, coupled with the characteristics of the wind pump itself, the use of the water warehouse location of the water is very shallow, resulting in a short working time in the case of the wind pump drain water also continue to run on air, resulting in a significant reduction in the service life of the wind pump, and at the same time to continue to run a large number of gas to be consumed, resulting in the coal mine pressurized wind oxygen system air pressure source is insufficient At the same time, continued operation will consume a large amount of air source, causing insufficient air pressure source in the coal mine pressurized air oxygen supply system, which is easy to cause safety risks. In view of the above problems, our company has developed a full air-controlled wind pump automatic drainage device, which is designed to be lightweight and easy to install, and can realize that the wind pump works with water and stops without water. Reduce the labor force and the failure rate of the wind pump, improve the work efficiency, but also to avoid the waste of air. It realizes energy saving and emission reduction, saves manpower and material resources, and brings great economic benefits to the society.
