Test pump how to work? Interpretation of working principle of pressure test pump

As a device for filling and testing various kinds of water, the pressure test pump plays an important role in the water industry and laboratory testing and is a "good hand" for people's daily production and life Pump is how to run the work, the basic working principle is what? This small series for you to interpret the working principle of the pressure test pump. How to buy a well-intentioned pressure test pump product test pump works: Cam driven by the motor rotation. As the cam pushes the plunger up, the seal formed by the plunger and the cylinder decreases in volume, the oil is squeezed out of the sealed volume and drained through the check valve to where it is needed. When the cam rotates to the descending part of the curve, the spring forces the plunger down to create a certain degree of vacuum, and the oil in the tank enters the sealed volume under atmospheric pressure. The cam continuously raises and lowers the plunger, periodically reduces and increases the volume of the seal, and the pump continues to suck and drain oil. The above is the basic principle of pressure test pump, hope to help you understand and test pump products.
