As the double suction pump is widely used in industrial production. Double suction pump impeller is combined by two back-to-back formed from the impeller flow into a volute. Double suction pump has the following features: it is equivalent to two of the sa

Double suction pump is a centrifugal pump is widely used in China, the scientific research personnel after years of market survey, designed for city water supply, heating, air conditioning and refrigeration industry R & D and production of double suction

Double suction pump is a centrifugal pump is widely used in China, the scientific research personnel after years of market survey, designed for city water supply, heating, air conditioning and refrigeration industry R & D and production of double suction

Now on the market a wide variety, all kinds of, but want to choose a good quality and affordable price, it will need to spend time to study, take the pump as an example, when you want to buy a good sewage pump, do you know how to see the quality of it? He

The installation position of the pump should meet the requirements of the multi mud Shahe flow to allow the suction on the vacuum height, the foundation must be level, stability, and ensure that the rotation direction of the power machine is in line with

Stainless steel pump is a kind of pressure to raise the water level of the tool, it is mainly dependent on the work of the piston movement, which has a great impact on the use of such products. Stainless steel pump can be divided into centrifugal pump, ax

Single-stage pump is composed of an impeller pump, the general level of the highest single pump head only about 100 meters. The centrifugal pump has the advantages of simple structure, stable performance, high speed, small size, light weight, high efficie

Power is generally refers to the body in unit time of power, that power is a physical quantity describing the work speed. The number of work must be, the shorter the time, the greater the power value. For centrifugal pump, it is in the process of operatio

Mixed flow pump impeller flow direction and pump performance between the centrifugal pump and axial flow pump, the structure also has the corresponding characteristics. Mixed flow pump pressurized water chamber with volute and the guide vane Shizhi, which

The seal of the pump comprises a seal between the pump shaft and the adjacent parts, and the seal at the connection point of the various parts of the pump. At present, the treatment of relatively static parts of the static seal is relatively easy, using n

In practical work, the performance of the pump needs to be adjusted. This is because the water pump in the pump and the pipeline under the circumstance of only one point, if the pump operating point parameters do not meet the actual needs, it should be us

There are many kinds of water pumps, and the structure is very different. Filling pump and vane pump structure is completely different, the simulation analysis of the demand is different; the same type of pump, the volume of the pump is different, the pro

At present, the variable speed regulation method of the air conditioning cold and hot water circulation pump has constant pressure difference control, fixed terminal pressure difference control, minimum resistance control and temperature difference contr

Axial flow pumps can be divided into two types according to the installation method, which can be divided into common seat type and block type. The motor and the transmission device are directly arranged on the pump structure, and the whole pump is shared

Operation practice shows that the axial flow pump, the outer edge of the impeller part due to cavitation and damage, which is caused by the gap cavitation, cavitation phenomenon of two airfoil cavitation.

Due to the different structure of various pumps, especially the shape of the impeller is very different, so the performance of the pump also has a greater difference.

1. In the operation of the equipment in the process of personal failure or sudden rupture of a part of the unit.

2. Centrifugal pump body or bearing a high fever of more than the maximum limit.

2. Centrifugal pump body or bearing a high fever of more than the maximum limit.

Mixed flow pump is widely used. It is mainly used for farmland irrigation and drainage, power plant water supply, urban water supply, shipbuilding and ship propulsion.

Centrifugal pump is a centrifugal force generated by the rotation of the impeller to pump the water into the impeller, according to different ways, can be divided into 2 kinds of single suction and double suction. According to the number of impeller insta

In the chemical process, the liquid is transported by the pump, and the different types of chemical production and technological process are different. Is the viscosity. The high viscosity liquid from industrial water to hundreds of thousands of cps. As f

The mechanical seal leakage of boiler feed pump is the most common fault, on mechanical seal leakage of maintenance work accounted for more than 50% of the total amount of maintenance, for the normal operation of the water pump and a small amount of seal

Multistage pump is a pump with two or more than two impeller. Usually the structure has the spiral case type multistage pump and the sectional type multistage pump.

1. Suction pipeline :
Suction diameter: suction diameter should be slurry pump inlet diameter equal to or with a pump inlet diameter ratio is slightly larger, the principle is not only avoid pump cavitation, and cannot make slurry formation of deposits

Axial flow pump and mixed flow pump structure is relatively simple, operation is not complicated, the operation is more reliable. But if the manufacturing quality is not high, improper installation, operation and maintenance is not good, repair is not tim
