There is a positive correlation between the number of revolutions and flow of a screw pump. In practical applications, it is necessary to select a suitable range of revolutions according to specific needs and equipment characteristics to ensure stable operation and efficient pumping of the equipment.

There is a close relationship between the number of revolutions and pressure of the screw pump. In practical applications, it is necessary to select a suitable range of revolutions according to specific needs and equipment characteristics to ensure stable operation and efficient pumping of the equipment.

There is a close relationship between the number of revolutions and viscosity of the screw pump. In practical applications, it is necessary to select the appropriate speed range according to the viscosity of the fluid and the design requirements of the pump to ensure stable operation and efficient pumping of the pump.

The relationship between the pump shaft power and the motor power is complex and close. In the process of pump selection and application, it is necessary to comprehensively consider multiple factors to ensure the normal operation and high efficiency of the pump system.

although power is an important indicator for measuring the performance of a pump, multiple factors such as actual needs, efficiency, quality and reliability need to be considered when choosing a pump. Therefore, it cannot be simply said that "the greater the power, the better the pump".
