Diaphragm pumps are designed to protect columns and cylinders by separating the liquid being pumped from the columns and cylinders with the aid of a membrane. The left side of the diaphragm in contact with the liquid are made of corrosion-resistant materials or coated with a layer of corrosion-resistant substances; the right side of the diaphragm is filled with water or oil.
Diaphragm pumps, also known as control pumps, is the main type of actuator, by accepting the control signal output from the regulator control unit, with the help of power operation to change the fluid flow. Diaphragm pump in the control process is to accept the regulator or computer control signals, change the flow of the regulated medium, so that the regulated parameters are maintained in the required range, so as to achieve the automation of the production process. If the automatic adjustment system compared with the artificial adjustment process, the detection unit is the human eye, regulation and control unit is the human brain, then the implementation of the unit - diaphragm pump is the human hand and foot. To achieve the process of a parameter such as temperature, pressure, flow, level and other regulatory control, are inseparable from the diaphragm pump.
Air operated diaphragm pumps are commonly used in five materials: plastic, aluminium alloy, cast iron, stainless steel, Teflon. Electric diaphragm pumps have four materials: plastic, aluminium alloy, cast iron, stainless steel. Diaphragm pump diaphragm according to different liquid media were used nitrile rubber, neoprene, fluorine rubber, PTFE, PTFE, etc. placed in a variety of special occasions, used to pump a variety of media to meet the needs.
