Dalian pneumatic pump manufacturer address, pneumatic pump is a new type of conveying machinery, is a new domestic pump. Compressed air is used as the power source, which can be used to exhaust all kinds of corrosive liquid, liquid with particles, high viscosity, volatile, flammable and highly toxic liquid. It was invented by Wilton, an American engineer, and then pneumatic pump was introduced to China.

Dalian pneumatic pump manufacturers contact telephone, in the removal of the old diaphragm, often encounter trouble. Provide some additional advice on how to remove the old diaphragm. After the pump head is loose, adjust the stroke length to 10% before removing the pump head. It can ensure that the electromagnetic shaft has enough pressure to keep its connection stable, so that the diaphragm can be unscrewed. Pull the hydraulic end outward to release the screw from the socket.

Hold the liquid end and rotate counter clockwise. With a little resistance, the diaphragm can be unscrewed. The metered chemicals may crystallize at the hydraulic end, resulting in the ball and seat of the check valve not working properly. There may be gas leakage at the suction end of the metering pump. There may be a lack of O-ring or loose connection of suction valve on the suction side of hydraulic end. Move the hydraulic end by loosening the four pump head screws.

Rotate the stroke length to 10% and grasp the hydraulic end, then slide out from the screw hole, so the screws do not contact them, but still hold the back plate and diaphragm. Then rotate this part counter clockwise, with a little resistance, the diaphragm will come loose from the electromagnetic shaft. If the diaphragm is not loose, use some lubricating oil on the contact surface between the diaphragm and the electromagnetic shaft. After a few minutes, gently tap the diaphragm with a small plastic hammer.

There are five commonly used materials: plastic, aluminum alloy, cast iron, stainless steel, Teflon. Diaphragm pump according to different liquid medium respectively uses NBR, chloroprene rubber, fluororubber, polytetrafluoroethylene, polytetrafluoroethylene. Early domestic users through the importer agent to buy, expensive, cumbersome maintenance. With the progress of industry, the market share of domestic pneumatic diaphragm pump has exceeded that of imported products.
