Repair method of horizontal multistage pump cracking

In the process of using a horizontal multistage pump, the reasons for the cracking of the pump shell involve many aspects such as material, design, manufacturing and use environment. In order to avoid the cracking of the shell, it is necessary to choose high-quality materials, carry out reasonable design, strictly control the manufacturing process, and pay attention to the impact of environmental factors during use. Next, I will explain to you how to repair the cracking of the horizontal multistage pump housing.

Repair method of horizontal multistage pump housing cracking:

1) Preparation

Before repair can begin, you need to make sure that the pump has stopped running and is completely cooled. At the same time, disconnect all power and liquid connections with the pump to ensure the safety of the working environment.

2) Cleaning and pretreatment

Clean oil, scale and other impurities from the surface of the pump housing. If there is rust or corrosion in the cracked area, it needs to be cleaned and sanded to ensure good adhesion of the repair material.

3) Selection of repair materials

Select the appropriate repair material according to the material and cracking condition of the pump housing. Common repair materials are metal welding materials, polymer composite materials and so on.

4) Repair process

If welding repair is used, appropriate welding methods and parameters need to be selected to ensure welding quality. If polymer composites are used, follow the manufacturer's instructions to ensure that the material is evenly applied to the cracking area.

5) Post-repair treatment

After the repair is completed, the necessary post-treatment, such as grinding, polishing, etc., is needed to restore the appearance and performance of the pump housing.

6) Testing and verification

Test the repaired pump housing to ensure there are no leaks or other problems. This may include pressure testing, tightness testing, etc.
