Jining Dongda Hotline
Intelligent, efficient and energy-saving pneumatic dredging and sewage pumps for mines are a series of sewage pumps independently innovated, independently developed and owned by our company with independent intellectual property rights. Equipment and product technology are at the leading international level.
Mining pneumatic desilting and sewage pumps are powered by compressed air and are suitable for drainage and sewage treatment at coal mine underground mining working surfaces, roadways, bottom sewage pits, cesspools (wells), water silos, etc. that contain the risk of methane and coal dust explosions. Operation.
Structural components of mining pneumatic dredging and sewage pumps
Jining Dongda Hotline
The main components of mining pneumatic dredging and sewage pumps include the main body, control system and vacuum suction components.
Main part: composed of pump body, feed pipe, and discharge pipe
Control system: The control system mainly uses air-controlled reversing valves, travel switches, shuttle valves, and ball valves. Vacuum suction components: vacuum The suction component is mainly composed of a Laval nozzle that first shrinks and then expands, a negative pressure chamber and an expansion tube
Working principle of mining pneumatic dredging and sewage pump
Jining Dongda Hotline
, main body Part: It 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 reversing valves, travel switches, shuttle valves, ball valves and time logic reversing valves to realize the control and switching of the actuator to achieve the desired performance of the unit. The suction and discharge are switched in an orderly manner during work.
Vacuum suction assembly: The vacuum suction assembly is mainly composed of a Laval nozzle that first contracts and then expands, a negative pressure chamber and an expansion tube. 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.
