Description

Technical Field

[0001] The utility model relates to the technical field of pump bodies, in particular to a pneumatic pump housing. Background Art

[0002] Pneumatic pump is a new type of conveying machinery, which uses compressed air as the power source. It can completely pump out various corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. Diaphragm pump uses power operation to change the fluid flow rate. It is placed in various special occasions to pump various media that conventional pumps cannot pump. Diaphragm pump is a special form of positive displacement pump. It relies on the back and forth agitation of a diaphragm to change the volume of the studio to inhale and discharge liquid.

[0003] The cylinder head of the pneumatic diaphragm pump is mainly composed of a diaphragm to separate the transported liquid and the working liquid. When the diaphragm moves to one side of the transmission mechanism, the pump cylinder works as a negative pressure and sucks in the liquid. When the diaphragm moves to the other side, the liquid is discharged. The transported liquid is separated from the working liquid by the diaphragm in the pump cylinder and only contacts the pump cylinder, suction valve, discharge valve and one side of the diaphragm in the pump, but not the plunger and sealing device. The diaphragm is prone to wear at the edges after long-term use. However, since the outside of the diaphragm is a metal pump casing, when the diaphragm needs to be inspected, the pump casing can only be removed to observe the condition of the diaphragm, which is inconvenient and needs to be improved.
