What are the hazards of the pump running in a small flow area for a long time? Generally, the minimum flow rate of a centrifugal pump is 30% of the rated flow rate. If the pump runs in a small flow area for a long time, the hazards that come to mind are: 1. The temperature in the small-flow pump...

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 issues can...

. What is the main working principle of centrifugal pump? The motor drives the impeller to rotate at a high speed, causing the liquid to generate centrifugal force. Due to the centrifugal force, the liquid is thrown into the side channel and discharged from the pump, or enters the next stage...

27 basic knowledge points of centrifugal pump 1. What is the main working principle of a centrifugal pump? The motor drives the impeller to rotate at a high speed, causing the liquid to generate centrifugal force. Due to the centrifugal force, the liquid is thrown into the side channel and...

I Static equilibrium The static balance of centrifugal pump is calibrated on one calibration surface of the rotor. The residual unbalance after calibration is to ensure that the rotor is within the specified range of allowable unbalance in static state. It is also called static balance and...

Reasons for the failure of the mechanical seal of the centrifugal pump The following is an example of the failure of the mechanical seal of the centrifugal pump for the reference of maintenance personnel. (1) The flatness of the end face is not up to the standard or the surface is scratched; (2)...

Abstract: Centrifugal slurry pumps are widely used for short and medium distance hydraulic transport of solids through pipelines with medium requirements on head and pump outlet. The performance characteristics and erosion wear of pump components are the most critical design and selection...

Freeze protection of pumps and their piping Don't let the freeze happen Almost every industry has to deal with the potential danger of pipeline freezing. During mining, slurries and other liquids must be transported from point A in the pipeline to point B in the pipeline without flow...

First, we need to understand two concepts: temperature and absolute zero. Temperature is a measure of the heat present in a gas, liquid, or solid. The common temperature scales that everyone is familiar with are Fahrenheit and Celsius, which are two systems invented in the 1700s. The two systems...

18 selection standards for pressure reducing valves Principle one Within the given range of spring pressure level, the outlet pressure can be continuously adjusted between the maximum value and the minimum value of the pressure reducing valve, and there shall be no jamming and abnormal...
