Introduction Intelligent energy efficient mine pneumatic desilting sewage pump is my company independent innovation, independent research and development, with independent intellectual property rights of drainage equipment series, the product is an international leading water technology. The desilting sewage pump is driven by compressed air. And is suitable for containing methane or coal dust explosion hazard of the coal mine underground mining work surface, tunnel ,bottom hole water , sewage pit and drainage etc. We developed the desilting of sewage pump has realized the coal mine underground water sump coal slime and water mixture good efficient processing. The device completely solved heavy labor of artificial digging water sump, at the same time ,reduced a number of newly built underground water sump. And not only improved the comprehensive economic performance ,also realized environment management and protection ,save time and labor, and has widely practicability. Technology Features: 1.The series desilting sewage pump with advanced structure, convenient movement ,stable working ,working cycle is controlled by pneumatic timer, the pump body without any movement parts, Also can be adjustable according to timer to improve pumping efficiency. 2.Control system adopt advanced air control valve to realize actuator’s control and switch. High safety performance, reliable and sensitive actions.
