QYF series of mining pneumatic desilting and sewage pumps with leading sales volume

Pneumatic dredging and sewage pumps for mining Pneumatic dredging and sewage pumps
Product description of pneumatic dredging and sewage pump accessories
The series of pneumatic dredging and sewage pump accessories for mining are intelligent, efficient and energy-saving. They are independently innovative and independently developed by our company. , a series of sewage discharge equipment with independent intellectual property rights, and its product technology is at the leading international level.
The series of mining pneumatic desilting and sewage pump accessories are powered by compressed air and are suitable for underground mining working faces, roadways, bottom sewage pits, cesspools (wells), water silos, etc. in coal mines that contain the risk of methane and coal dust explosions. Drainage and sewage operations.
The series of mining pneumatic dredging and sewage pump accessories we have developed enable efficient and fast processing of coal slime and water mixtures in underground water silos in coal mines, completely relieving the heavy labor of manually clearing water silos, and at the same time reducing the cost of building new underground water silos. The number of bins not only improves the comprehensive economic benefits of mine water bin clearing, but also achieves environmental management and protection, saves time and effort, and has wide practicality.
Technical features of pneumatic dredging and sewage pump accessories
This series of dredging pumps has advanced structure, easy movement and stable operation. The working cycle is controlled by a pneumatic timer, and the pump body does not have any moving parts. The timer can be adjusted by yourself based on experience to improve pumping efficiency.
The control system uses advanced pneumatic valves to control and switch the actuator, with high safety performance, sensitive and reliable action.

Pneumatic dredging and sewage pump Accessories
Product structure and working principle
The main components of the series of mining pneumatic desilting and sewage pump accessories include the main part, control system and vacuum suction components.
. Main part: It consists of a pump body, a feed pipe, and a discharge pipe. Its job is to absorb and discharge materials.
. Control system: The control system mainly uses the organic combination of pneumatic reversing valves, shuttle valves, ball valves and time logic reversing valves to realize the control and switching of the actuator, so as to achieve the suction efficiency when the unit is working. Orderly conversion of materials and layout.
Vacuum suction component: It is designed based on the principle of Venturi effect and includes air supply port, exhaust port and vacuum port. When the air supply pressure at the air supply port is higher than a certain value, the nozzle shoots out a supersonic jet. Due to the viscosity of the gas, the high-speed jet sucks away the gas in the negative pressure chamber, causing the chamber to form a higher degree of vacuum. The performance of the vacuum generator is related to many factors such as the minimum diameter of the nozzle, the shape, diameter and relative position of the contraction and diffusion tubes, and the pressure of the air source. The vacuum suction component is connected to the suction port through the pump body. When the control system switches to control the cylinder operation, the suction and discharge process of the unit can be completed.
