10 common causes of broken shafts in pumps Many pump users wrongly blame the choice of shaft material when the shaft breaks, thinking they need a stronger shaft. But choosing this "the stronger the better" is often a temporary solution rather than a permanent solution. Shaft failure...

When the centrifugal pump is running, an axial force acts on the rotor, which will pull the rotor to move axially. Therefore, we must try to eliminate or balance this axial force in order to make the pump work properly. The axial force acting on the pump rotor consists of the following...

The difference between vertical and horizontal pumps Connection form: vertical pumps are superimposed and connected from bottom to top, horizontal pumps are arranged longitudinally on the base, vertical pumps are generally called pipeline pumps such as vertical pipeline centrifugal pumps, and...

The effect of pump inlet flow rate on the system The setting principle of the diameter of the outlet and the inlet of the heart pump: Generally, the outlet diameter is selected according to the economic flow rate, and the outlet diameter is determined according to the flow rate. When the pipe...

Teacher Guan Xingfan's "Modern Pump Theory and Design Manual" pointed out that when the pump is running, an axial force acts on the rotor, which will pull the rotor to move axially. Therefore, we must try to eliminate or balance this axial force in order to make the pump work...

The amount of movement of the multi-stage pump actually refers to the axial movement of the balance disc. So what causes the movement of the balance disc? First of all, understand the principle of action: The high-pressure water of the multi-stage pump produces a rightward force (axial force) on...

ABB price adjustment and discount system 2022 Dear colleagues: Hello everyone! In view of the instability of the supply of raw materials for bulk products caused by changes in the social environment, we continue to be deeply affected by the rise in the price of raw materials, the shortage of...

Whether the valve needs to install the principle and setting of the bypass valve We occasionally see some relatively large valves in some pipelines, and bypass valves are always installed. Why is this? What is its main function? Under what circumstances does it need to be installed? And what is...

Slurry pump cavitation solution, when the cavitation problem occurs, how to solve it according to the problem? The condition of pump cavitation is determined by the pump itself and the suction device. Therefore, when studying the conditions for cavitation, the pump itself and the suction device...

Hierarchical management of pump and related mechanical equipment maintenance The classification and operation content of the maintenance of pumps and related machinery and equipment are determined according to the changes in the technical conditions in actual use; the structure of the equipment;...
