Overview of pneumatic diaphragm pump
Pneumatic diaphragm pump is mainly used for mine roadway development, shaft shaft construction, mining working face trough and various Sewage discharge around equipment, drainage, sewage sand discharge, mud discharge in underground cavern projects, white spray applications in mine tunnels, etc. The pneumatic diaphragm pump produced by our company adopts, absorbs and improves the most advanced pneumatic diaphragm pump production process and technology in the world. This product is specially designed for coal mines and has traditional submersible electric pumps, mud pumps, impurity pumps and flexible shaft pumps. All functions are a revolution in traditional mining water pumps. The key is to completely solve the safety issues of traditional water pumps. The product can provide high conveying speeds at low air pressures and is compatible with a wide range of materials. This water pump has an anti-stall design and a modular pneumatic motor/fluid part.
Pneumatic diaphragm pumps are used to discharge clean water underground in coal mines, or sewage containing solid particle impurities (volume concentration less than %). They can also be used in non-coal mines and other occasions with similar transmission media.
Inflation method
Edit
The structure of the diaphragm pump air chamber is generally to separate the water chamber from the air chamber. After the air chamber is filled with compressed air, the pulsation of the water in the water chamber is absorbed by the compressed air in the air chamber through the rubber diaphragm. The function of the air chamber is to use the compressibility (or elasticity) of air to absorb the pulsation of the water output from the diaphragm pump and stabilize it. The flow of water entering the system is basically smooth. However, in order to achieve the requirement of basically stable water flow, it is required that the air pressure in the air chamber should be compatible with the water pressure.
How to inflate the air chamber of the diaphragm pump. Before the diaphragm pump operates, first inflate the air chamber to a pressure greater than the working pressure of the pump. Drive the diaphragm pump and adjust it to the working pressure. At this time, you can see that the water outlet hose of the pump is shaking violently. Take a needle-like object and hold it against the air nozzle to deflate. As the deflation progresses, the shaking phenomenon of the water outlet hose will gradually disappear. After the water outlet hose is stable, stop deflating.
Structure of pneumatic diaphragm pump
Pneumatic diaphragm pump is composed of water outlet manifold, pump cover, pump body, water inlet manifold, diaphragm, ball, ball seat, outlet pipe, slide valve, muffler, piston, Composed of air inlet pipe, water inlet section, etc.
Working principle of pneumatic diaphragm pump
Mining pneumatic diaphragm pump uses the pressure difference in the air chamber to alternately generate suction liquid pressure and positive liquid pressure in the liquid chamber, and controls the valve switch to Ensure positive flow of liquid. After ventilation, the pump starts running and works continuously to ensure that the required pressure remains constant. The pump will increase and maintain the delivery pipe pressure, and when the maximum delivery pipe pressure is reached (or the distribution valve is closed), it will stop working and when needed time, resume pumping.
Technical features of pneumatic diaphragm pump
The pneumatic diaphragm pump for mining uses air flow to push the valve core to reciprocate, so that the pressure air enters the left and right air chambers alternately, causing it to push the diaphragm to reciprocate and make the working chamber A pressure difference is generated inside to achieve the purpose of water absorption and drainage. It is small in size, light in weight, and does not require a foundation. It can be used as a mobile pump without lubrication. The main valve has no special requirements for the air source and can be started by self-priming.
