Description

Pneumatic double acting pump

This creation is about a pneumatic double-acting pump, especially a pneumatic double-acting pump that can output fluids in at least two different areas at a time, and can easily and accurately adjust the fluid delivery frequency and flow rate.

According to the conventional pump system, the main body is composed of a body, a motor and a blade. The motor is mounted on one side of the body, and the drive shaft connected to the motor is inserted into the body to be combined with the blades located in the body. When the motor is actuated, the fluid is introduced into the body from the inlet of the body side, and is pressurized by the blade to output the fluid from the outlet of the body, thereby increasing the fluid delivery pressure and lowering the fluid from low to high. Push at the place.

However, the hydraulic thrust of the existing pump is caused by the centrifugal force generated by the motor to drive the blade. In order to obtain the centrifugal force required to pressurize the fluid, the motor speed must maintain a high rotational speed; however, the high-speed running motor not only consumes energy and causes component wear, but It will also cause the internal temperature of the pump to damage the fluid quality. If the motor speed is to be reduced to reduce the damage rate of the pump and the damage to the fluid, it is found that the low-speed running motor cannot drive the blade to generate the centrifugal force of the pushing fluid and lose the pump function. Therefore, the existing pump is only suitable for rapid conveying and low fluid quality for conveying quality, and it is not suitable for thick fluids that need to be transported slowly, and the existing pump can only be used for single fluid transportation at one time, instead of Effects such as fluid transport in two or more areas.
