Water pump can transport many things, such as water, oil liquid metal, acid-base night and so on. It is a good means of transport.　　The delivery flow of screw pump has nothing to do with the delivery pressure. The delivery pressure is only related to the stage of screw pump, while the flow and speed have a strict positive proportional relationship. Therefore when it is necessary to control the conveying flow, it is only necessary to adjust the motor speed by equipped with frequency converter or realize stepless speed regulation by belt.　　 one method is to use ultrasonic method to detect whether the equipment has cavitation. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, it will not affect the detection results. Therefore, many pumps tend to have better measurement results when in use.consumption,　　As a submersible slurry pump widely used in many fields, it has the advantages of simple structure, convenient disassembly and maintenance, and convenient installation and use. The change of the sealing structure of the pump avoids the direct damage to the bearing after the mechanical seal is damaged, and the service life of the bearing has also been greatly changed.　　Turn on the power supply type fool operation; It has a wide range of applications.
