Introduction: There are two common installation parts in my design. One is to set the joint at the inlet and outlet of the water pump immediately. The other is to set the joint after the diameter change. There are three reasons for this proposal: 1. The installation is convenient. If the inlet and outlet of the centrifugal pump are set with joints immediately, it is often impossible to guarantee

Now, there are two common installation parts in my design. One is to set the joint at the inlet and outlet of the water pump immediately. The other is to set the joint after the diameter change, and then the proposal is to build the joint after the diameter change,

There are three reasons: 1. The installation is convenient. If the inlet and outlet of the centrifugal pump are connected immediately, the direct connection can not be guaranteed, but a short pipe needs to be lifted. Because the inlet and outlet flange of the centrifugal pump and the joint flange are often not directly connected due to the working pressure, it is not necessary to consider this problem when installing on the connecting pipe after the diameter change?

2. The design is convenient. If the joint is installed after the diameter change and its specification is consistent with the pipe diameter, the total number and specification of the joint can be counted in advance. If it is installed at the inlet and outlet of the centrifugal pump, it is necessary to wait for the material of the centrifugal pump to return, and the statistical analysis is very easy to be incorrect.

3. To prevent gas gathering, if the water inlet and outlet of the water pump el is installed immediately, because the joint is annular, part of it will be higher than the pipeline, resulting in gas gathering. It is harmful to the normal moisture absorption of the water pump. The pipeline of the fire pump room in our enterprise is generally installed in the pipe trench, and the design elevation is low. It is not easy to cause great harm when the joint is installed in this part.

in general, Rubber joint It is indispensable in the pipeline installation of water pump Expansion joint Incorrect model selection will cause great harm to pipeline system software. As a designer, it is necessary to carefully complete the design scheme. Only under the premise of understanding and grasping the condition of the machine and equipment can we choose the appropriate type of rubber joint. The characteristic decision of rubber joint is a kind of malleable connection component. The rubber joint is divided into the arc area in the middle. The selection of these two forms should be based on the material in the pipeline. If the material contains sand particles, the sand particles will gather in the arc-shaped area during the whole process of material transportation, which is easy to produce vortices and sand deposition, which will cause immediate damage Compensator The service life of. At this time, it is more suitable to select filledarch rubber joint. It should be noted that the working capacity of the two kinds of compensators is different, which should be fully considered.
