Pump system noise is transmitted through two main ways, that is, through the spread of airborne noise through the air and through the floor walls and ceiling spread of structural noise.
Noise pump system adopting some measures although decreased, but th

Submersible pump can be placed under the water, the centrifugal pump on the ground. Here is a look at the difference between the two.
Submersible pump is a very wide range of water treatment tools. The difference is that it works in the water, while the

Multi-stage pump is a centrifugal pump, is to rely on the rotation of the impeller in the acquisition of centrifugal force. When the gas density reaches the working range of the mechanical vacuum pump, the vacuum pump is drawn out.

The use and maintenance of the motor is often ignored, a motor can play the maximum economic benefits, to extend the service life, the correct use and routine maintenance is a key issue.

1.Mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or pump shaft deformation and bending, resulting in multi impeller, direct friction with the pump body, or bearing damage, it is possible to reduce the pump speed.
2.Hu

1.The pump after the closure, to put the water left in the water pump and a pipeline, and the external soil clean, lest the frozen water in the ice after the pump body and a water pipe burst.
2.At the end of the pump, cast iron pipe and other parts, sho

Quality products from excellent design, but also depends on the reliable guarantee of excellent manufacturing, and excellent manufacturing depends on the perfect processing technology. Only choose the correct processing technology, to create a high precis

Compared with other mechanical oil production, the submersible electric centrifugal pump has the characteristics of large displacement, wide lift range, large production pressure difference, long working life, simple ground processing equipment and so on.

Compared with other mechanical oil production, the submersible electric centrifugal pump has the characteristics of large displacement, wide lift range, large production pressure difference, long working life, simple ground processing equipment and so on.

Submersible multi-stage centrifugal pump assembly can be divided into the floating pump, partial pressure pump and the overall pressure pump. The structure can be divided into two parts, namely, a rotating part and a fixed part, a rotating part of main sh

Cause of failure :

1.Pump stuffing box packing pressure is not tight.
2.The packing in the packing box of the water pump is filled with the error or the material of the filler and the variation of the characters.
3.Pump shaft bending.
4.Cooling w

Submersible sewage pump because of its installation is simple, small size, easy maintenance, no noise and other advantages, widely used in engineering, factories, commercial, hospitals, hotels, residential areas, such as sewage discharge. At present, Chin

In the pumps, there is a serious problem, no matter what kind of pump belongs to the ranks of pump products as long as there is such a problem: no water! Here we talk about the reasons that lead to the deep well pump does not have the water?

Improving the anti cavitation performance of the pump :
1. reduce the necessary cavitation margin:
1). The double suction impeller pump. The double suction pump NPSH delta HC than single stage single suction pump NPSH HC, N and Q for the same speed flo

The head and the pipe may be inconsistent with the requirements of general pressure flow, the centrifugal pump, or the production tasks, process requirements change, this time is required to pump flow regulation, essence is to change the operating point o

Method 1: the opening of the outlet valve adjustment
Method two: bypass valve adjustment
Method three: adjusting the diameter of the impeller
Method four: speed contro

The efficiency of the pump is the key to whether the power is completely converted to mechanical energy:
1.Water pump in the coil, the power will heat, it shows that a part of the electric power can be consumed by the coil resistance.
2.The pump has be

As we all know, the pipeline is a kind of solid, the water is easy to flow of material within the pipeline, if the water is flowing, there must be a part of the energy into heat and "destroy", which is the loss of part of water (or head), which is a ref

1. Check the parts: submersible pump impeller, ring, sleeve, bearing and others are wearing parts. The first part of the pump should be removed, check whether the vulnerability is intact. Use of damage and non qualified spare parts.
2. Replace the lubr

The maintenance of centrifugal pump vertical pipe parts and repair according to the content and workload, divided into minor repairs, repair, overhaul and overhaul system four.

To ensure the efficient operation of pumps is an important link to improve the efficiency of high temperature magnetic pump pumping station. The efficiency of pump is related to the design and manufacture level of pump, the running of pump and the managem

Scope of application
Fire, cooling equipment, applicable to offshore seawater desalination, can also be used as a ground source heat pump heating in all coastal areas, enhance the use of coastal seawater, fountain square landscape, marine aquaculture, d

1.Has not been installed pumps should be coated with a layer of suitable anti rust agent in unpainted surface, oil lubricated bearings should be filled with the appropriate oil, with grease lubricated bearings should only be filled with a kind of grease,
