Shanxi pneumatic dredging and sewage pump-safety valve manufacturer direct sales

Product Description of Pneumatic Dredging and Sewage Pump Safety Valve Series Mining Pneumatic Dredging and Sewage Pump Accessories are intelligent, efficient and energy-saving. They are a series of sewage equipment independently innovated, independently developed and owned by our company with independent intellectual property rights. The product technology is at the leading international level. Accessories include safety valves, nozzles, suction heads, suction pipes, control valves, etc. Pneumatic safety valves play a very important role as accessories of sewage pumps.
The series of mining pneumatic desilting and sewage pumps are powered by compressed air and are suitable for drainage of underground mining working surfaces, roadways, bottom sewage pits, cesspools (wells), water silos, etc. that contain the risk of methane and coal dust explosions. Sewage operations.
The series of mining pneumatic desilting and sewage pumps we have developed realize efficient and fast processing of slime and water mixtures in underground coal mine water tanks, completely eliminating the heavy labor of manually digging water tanks, and at the same time reducing the cost of building new underground water tanks. Quantity, not only improves the comprehensive economic benefits of mine water storage clearing, but also realizes environmental management and protection, saves time and effort, and has wide practicality.
Features of pneumatic dredging and sewage pump safety valves and other 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 sewage safety valve
to realize the control and switching of the actuator, with high safety performance, sensitive and reliable action.
The safety valve of pneumatic dredging and sewage pumps is suitable for the following models of pneumatic dredging and sewage pumps

The working principle of the safety valve and other accessories of pneumatic dredging and sewage pumps
The main components of the series of pneumatic dredging and sewage pump accessories for mining include the main body, control system and vacuum suction components.
The main part consists of a pump body, a feed pipe, and a discharge pipe. Its job is to suck and discharge materials.
, control system The control system mainly uses the organic combination of pneumatic dredging and sewage pump safety valves
, shuttle valves, ball valves and time logic reversing valves. Pneumatic dredging and sewage pump safety valves
/>Realize the control and switching of the actuator to achieve orderly switching between suction and discharge when the unit is working.
, Vacuum suction assembly is designed based on the principle of Venturi effect, including 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.
