twin screw pump
Analysis of the characteristics of twin screw pumps used in oil fields
The twin screw pump is a positive displacement pump with active screw meshing. There are many structural forms. Today, let's talk about the characteristics of the oilfield twin screw pump.
1. Large flow and high efficiency
According to the previous oilfield twin-screw pump business, the flow rate of twin-screw pumps used in oilfields is relatively large. This should be due to the oilfield oil production tasks and increase oil well production. The twin-screw pump adopts a double-suction structure and has high working efficiency.

high viscosity gear pump
How to select the correct type of internal gear pump?
Internal gear pumps are also called high-viscosity pumps or high-viscosity gear pumps. They are different from ordinary external gear pump gears. The internal gear pump consists of an outer rotor, which is separated and fixed by a crescent plate and a pin. The rotor, the inner and outer rotors run in the same direction, and they are relatively stable after running, with low noise and no pulsation. Especially suitable for conveying highly viscous materials.

chemical centrifugal pump
What are the abnormal noises and vibrations of chemical centrifugal pumps?
There are mainly the following two factors that cause abnormal noise and abnormal vibration of the centrifugal pump.
​​​​​​​In terms of medium:
1. It is possible that the centrifugal pump sucks debris into its internal structure, causing blockage or damage to the impeller. At this time, shut down immediately and take quick cleaning at the same time;
2. The flow rate of the centrifugal pump has relatively large fluctuations, which leads to pressure changes, and then produces abnormal noise and abnormal vibration.
3. The suction stroke is too large, causing serious cavitation at the entrance of the impeller, that is, the water flowing on the impeller produces certain bubbles in the low-pressure zone, and these bubbles are destroyed in the high-pressure zone, which will produce Certain impacts, such impacts are more serious, and vibrations will find abnormalities. If this happens, the installation height of the centrifugal pump should be lowered.
