The products of pneumatic pump manufacturers come in four materials: engineering plastic, aluminum alloy, stainless steel, and cast iron. Pneumatic diaphragm pumps use nitrile rubber, chloroprene rubber, fluororubber, polytetrafluoroethylene, polytetrafluoroethylene, etc. according to the medium of the liquid being pumped, to meet the needs of different users. Since its production, this pump has been adopted by more than 1000 domestic petroleum, chemical, electronic, ceramic, textile, paint, pharmaceutical machinery system units, installed in various special occasions, used to pump various media that cannot be pumped by conventional pumps, and can replace gear pumps as a theoretical product, all of which have achieved satisfactory results.

When starting and stopping the pump, simply open and close the gas valve. Even if the pump is started for a long time or suddenly shut down due to unexpected circumstances, it will not be damaged. Once overloaded, the pump will automatically stop and have self-protection capability. When the load returns to normal, it can automatically start running again. Good flow performance, able to pass through medium with large particle diameter of 10mm. When transporting mud and impurities, there is minimal wear on the pump.

Introduction to the working principle of pneumatic pumps by pneumatic pump manufacturers

The working principle of pneumatic pumps is to rely on compressed air as power. When the diaphragm is under high pressure air, it moves to the designated position with the diaphragm. The air valve can control compressed air to slowly flow into the space behind the diaphragm. After pushing the diaphragm with compressed air, it moves away from the intermediate and uses the connection of the connecting rod to move the diaphragm towards the intermediate. On the other side, the diaphragm utilizes hydraulic action to flow the medium in the compression membrane chamber onto the valve ball at the inlet, driving the contact between the valve seat and the valve ball to seal the inlet pipeline.

Hydraulic action acts on the ball valve at the outlet, opening the outlet pipeline. The ball valve at the outlet closes due to pressure, while the ball valve at the inlet opens due to pressure, allowing liquid to flow into the pump chamber. After the stroke is completed, compressed gas is injected into the back of the diaphragm again, and the diaphragm begins to move towards the intermediate. The rest behind the diaphragm is also discharged from the pump.

The sudden drop in pressure of the pneumatic diaphragm pump is usually caused by insufficient oil replenishment. The energy-saving company of the water pump suggests that you can contact professional staff to repair the oil valve. It cannot be ruled out that it is due to not reaching a certain amount during feeding or oil leakage. It is necessary to check the feeding situation and try to control the oil leakage as much as possible.

Diaphragm pumps, with their excellent features of versatility and reliability, have become a widely used solution in various application fields, from the petrochemical industry to the food industry, from the chemical industry to the mining industry. Double diaphragm pumps belong to the positive displacement pump series, using compressed air as the main power source. Especially, compressed air is transmitted from one chamber to another through a shaft located in the central part, which allows the chambers to move simultaneously.
