Pneumatic diaphragm pump is a special positive displacement pump, it through the use of diaphragm reciprocating motion to transport fluid, is a new type of fluid transport equipment.
Pneumatic diaphragm pump is mainly composed of transmission mechanism, diaphragm assembly, valve body and pump body. The transmission mechanism adopts the CAM structure. The shape and size of the CAM is one of the core technologies of the diaphragm pump, which determines the flow, working pressure and stroke of the diaphragm pump. The diaphragm assembly is composed of a diaphragm, a liner and a liner seat, etc., which separates the fluid chamber of the pump from the atmosphere, so as to achieve the purpose of fluid transportation. The valve body is composed of the disc, the seat and the cylinder block. It controls the flow and direction of the fluid, so that the fluid can be transferred according to certain rules. Pump body is the main body of the pump, it puts the transmission mechanism, diaphragm assembly and valve body together, forming a complete pump.
The working principle of pneumatic diaphragm pump is: when the CAM rotates, the curve contour of the CAM pulls the diaphragm to the suction side or the discharge side, so that the diaphragm and the cylinder space to achieve fluid exchange, so as to achieve the purpose of fluid transportation. When the CAM rotates to a certain position, the diaphragm will separate the cylinder space from the atmosphere, so that the fluid can not flow back to the atmosphere, thus achieving one-way fluid transport. In addition, there is an eodd pump, the principle is similar, only the power source is the motor.
Pneumatic diaphragm pump has many advantages, such as a wide range of flow regulation, can achieve stepless speed regulation, can transport high viscosity or containing solid particles of the medium. In addition, the pneumatic diaphragm pump also has the advantages of strong self-priming ability, simple maintenance and low noise. Therefore, pneumatic diaphragm pump is widely used in chemical, petroleum, pharmaceutical and other fields, is an ideal fluid transport equipment.
When you have to start working with any pump control system, whether the pump be a HVAC pump or a VFD pump in NYC, it’s very important to know the basics first.
You must follow some steps to check the rotation of pump.
