What is the pump pumping, and how to choose the type?

Split box pump (split circulation) is also known as single-stage double-suction centrifugal pump, and its main feature is the large flow rate of the conveying medium. The working principle of the operation of the split case pump: The impeller is installed in the pump casing and fastened to the pump shaft, which is directly driven by the motor.

The pump casing** has a liquid suction connected to the suction pipe. The liquid enters the pump through the foot valve and suction pipe. The liquid discharge port on the pump casing is connected to the discharge pipe.

When the speed of the pump is constant, its pressure head and flow rate are related to the diameter of the impeller. It is widely used in petroleum, chemical industry, electric power metallurgy, mining, ship selection, light industry, agriculture, civil and national defense departments, and occupies an important position in the national economy. Changsha Zhonglian Pump Industry has more than 30 years of experience in the production of Zhongkai pumps, and we have 10,000+ cooperation units, and the selection of **...

Zhongkai pump is suitable for factories, cities, mines, power stations, farmland, water conservancy projects and other fields. It is used to convey clean water without solid particles or other liquids with physical and chemical properties similar to water, and the temperature of the medium to be conveyed is 0 80, and the maximum permissible inlet pressure is allowed.

Split case pump selection steps.

1. List the basic data of the split box pump

Including: the characteristics of the medium, the diameter and content of the particles contained in the medium, the temperature of the medium, the required flow rate and pressure piping system data.

2. Determination of flow rate.

a. If the minimum, normal and maximum flow rate has been given in the production process, it should be considered according to the maximum flow rate.

b. If only the normal flow rate is given in the production process, a certain margin should be considered.

For NS>100 large flow and low head pumps, the flow margin is 5%, for the small flow of NS<50 high lift and pump, the flow margin is 10%, for the 50 ns 100 pump, the flow margin is also 5%, and for the pump with poor quality and poor operating conditions, the flow margin should be 10%.

c. If the basic data is only given by weight, it should be converted into volumetric flow.

The pump body is divided into two parts, loosen the fastening bolt during maintenance, and the inner cavity structure of the pump can be seen after the upper cover is removed, which is generally used to pump slurry pumps containing solid particles. The selection method is the same as that of ordinary centrifugal pumps.

Question: The pressure that the material of the pump body and pump cover can withstand is, isn't the working pressure very dangerous, not only has no margin, but also overloads?

Compared with other pumps of the same type, Kailite split box pump has the characteristics of long life, high efficiency, reasonable structure, low operating cost, convenient installation and maintenance, etc., and is an ideal pump for fire protection, air conditioning, chemical industry, water treatment and other industries. The design pressure of the pump body is 1 6MPa and 2 OMPA.
