Centrifugal pumps are prone to cavitation, which is related to many factors. What is the purpose of cutting the pump impeller and what role does it play? 1、 Cutting of Centrifugal Pump Impeller 1. Purpose of cutting: A centrifugal pump has only one performance curve at a certain speed. To expand the working…

When conducting maintenance and testing on fluorine lined centrifugal pumps after assembly, in addition to following normal maintenance procedures and standards, the following points should also be noted: 1. The concentricity of the pump rotor and volute. The degree of concentricity between the pump rotor and the volute is completely determined…

Pipeline centrifugal pump is a type of centrifugal water pump suitable for industrial and urban water supply and drainage, pressurized water supply in high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC refrigeration circulation, bathroom and other cold and warm water circulation pressurization and equipment matching. The liquid that…

At present, many enterprises have started to use concentrated sulfuric acid horizontal chemical pumps for the transportation of various materials. In actual use, this high-quality product has won high praise from many enterprise users. However, although many users often use this product, they still have no knowledge of its features…

(1) Motor reversal Due to wiring reasons, the direction of rotation of the motor may be opposite to the actual requirement of the sewage pump. Therefore, when starting, it is generally necessary to observe the direction of rotation of the sewage pump. If the direction of rotation is reversed, any two…

What situations should everyone pay attention to when using self priming magnetic pumps in order to better use them? Many people are curious about this issue. Today, centrifugal pump manufacturers have brought some precautions for the correct use of magnetic pumps. Friends who are not familiar with it should come…

Clear water pump is used for conveying clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, pressurized water supply in high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC refrigeration cycle, farmland irrigation…

With the increasing environmental protection situation, more and more chemical enterprises are required to use magnetic pumps to transport various corrosive materials. As is well known, magnetic pumps cannot idle. As long as they idle for a few minutes, the friction between the shaft and the sleeve inside them will…

When a centrifugal water pump is blocked by waste, it is necessary to pull the pump up in order to sort it, which is very inconvenient and therefore rarely used in practical activities. Therefore, using a submerged pump to carry out low-level transportation solves the problem of low-level transportation. However, due…
