Pneumatic diaphragm pump is a new generation of transmission machinery and equipment, it is a very popular product in our country, is currently the most novel kind of pump. The use of compressed gas as the power source, pneumatic diaphragm pump for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquids can be handled well. Pneumatic diaphragm pump has four materials: plastic, aluminum, cast iron, stainless steel. Pneumatic diaphragm pumps are based on different liquid medium were nitrile rubber, neoprene, fluorine rubber, PTFE, polyhexamethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a variety of conventional pumps can not be aspirated medium, have achieved satisfactory results.
Pneumatic diaphragm pump is characterized by: its simple and multi-channel flow control.
There are generally two ways to achieve flow control:
1, by controlling the pressure of compressed air (gas source) to regulate the pressure, the other conditions remain unchanged, the pressure level is proportional to the size of the flow.
2, by adjusting the size of the pump outlet valve can also be completed flow adjustment.
In practice, by adjusting the air supply pressure to adjust the flow rate for the first choice, this adjustment is more convenient, but also to ensure that the pump life and energy loss! Pneumatic diaphragm pump is a new type of conveying machinery, the use of compressed air as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquid can be smoked exhausted .
Pneumatic diaphragm pumps can not only pump liquid but also transport difficult-to-flow media. It has many advantages such as self-priming pump, submersible pump, shield pump, mud pump and impurity pump. As its share of the pump industry in our country continues to increase, its research and use have drawn the attention of all circles.
