The diaphragm pump, also known as the control pump, is the main type of the actuator. By accepting the control signal of the control unit output, it can change the fluid flow with the help of power operation. The diaphragm pump is generally composed of execution agencies and valves. If the power used by the execution agency it is equipped, the diaphragm pump can be divided into three types: pneumatic, electric, and liquid dynamic, that is, the pneumatic diaphragm pump with compressed air as the power source, an electric diaphragm pump with electric power source, and a liquid medium with a liquid medium (Such as oil, etc.) Pressure is an electrical dynamic diaphragm pump. In addition, according to its functions and characteristics, there are also electromagnetic valves, electronic, intelligent, and on -site bus -type diaphragm pumps. There are many types of products in diaphragm pumps, various structures are diverse, and they are constantly updating and changing. Generally speaking, the valve is general, which can be matched with the pneumatic execution agency, or it can be matched with the electric execution agency or other executive agencies.
