The operation of screw pump and gear pump may not be understood by some people. Today, Xiaobian of koyu machinery tells you the slip leakage phenomenon of screw pump and gear pump and the measurement characteristics of flow volume.

In the detailed description of details of each kind of screw pump before the operation, we'll look at some common operating characteristics of the three screw pump. As mentioned above, the double screw pump can in every rotation axis from the same volume of liquid. This means that the discharged liquid flow is proportional to the speed. In other words you can control the flow speed, simply change the screw pump. The high viscosity liquid, can only measure the axis rotation measurement of the pump.

The structure of screw pump used with internal components and strict operation gap to some extent. Because of this gap, some liquid will flow back to the suction side of the discharge end. This phenomenon is called "sliding leakage (slip). The size of the amount of liquid leakage sliding part depends on the viscosity of the liquid, the internal gap pressure difference and the gear pump. Usually low viscosity will lead to leakage and more smooth, more viscous liquid, slip leakage will be smaller.

The gear pump will always try to emit the same amount of liquid, so it is important that equipped with some necessary overvoltage protection device in the system. Emission blockage in the three screw pump, often lead to increased pressure, the pressure rising phenomenon only in the following situations: when the load exceeds the motor stop
