The following is about how to correctly connect the multi-stage centrifugal pump water pipeline introduction, the user should be in use according to the actual situation of selection and installation, to maintain the stability and safe operation of the system.

如何正确接多级离心泵的引水管道？

1. selection of appropriate pipe material and diameter

When taking over the water pipeline of the centrifugal pump, the appropriate pipe material and diameter should be selected first. Generally speaking, the commonly used pipe materials include PVC, PP, PE, cast iron, etc., which should be selected according to the actual situation. At the same time, the pipe diameter should also be determined according to the pump outlet diameter to ensure smooth flow.

2. determination of pipeline route

When taking over the water diversion pipeline of the centrifugal pump, the pipeline direction shall be determined according to the actual use site, and the position of the water diversion port shall be lower than that of the water source, so as to ensure that the water can flow to the inlet of the centrifugal pump.

3. connection mode

The connection mode of centrifugal pump water diversion is flange connection, thread connection, clamp connection, etc., which should be selected according to the pipe material and size. When connecting, pay attention to the uniform fastening force and tighten it in turn.

Connection mode of water pipe and inlet and outlet flange

1. First measure the length of the water pipe and cut it to the required length.

2. Put the water pipe into the groove of the inlet and outlet flange, and tighten the nut to make it tightly connected with the flange.

3. Place the protective ring on the flange and fix it with bolts.

Connection between water pipes

1. Flange connection can be used to connect the ends of the water pipes to prevent water leakage.

2. Two water pipes can be connected using an adapter. When using the adapter connection, you must ensure that the adapter is correctly inserted into the two water pipes and tightened with screws.

4. considerations

1. A certain expansion margin should be reserved during pipeline installation to avoid affecting the operation of the pump due to pipeline changes caused by various reasons.

2. When taking over the water diversion pipeline of the centrifugal pump, it is necessary to ensure that the water diversion port will not be blocked by debris or the conveying water does not contain particulate impurities, so as not to cause wear or blockage to the pipeline.

3. After the pipeline is installed and connected, check whether each interface is tight and whether there is water leakage in the pipeline to ensure the safety and reliability of the system operation.

4. The pipeline of centrifugal pump water diversion should be maintained regularly to check whether the pipeline is defective and whether damaged materials need to be replaced.

5. When connecting the water pipe, it is necessary to ensure that the connection is tight to prevent water leakage.

6. When removing the water pipe, the valve must be closed first and the water in the water pipe must be drained to avoid the phenomenon of pumping with the pump.

7. When cleaning water pipes, avoid using corrosive chemicals such as acids and alkalis to avoid corroding water pipe materials and affecting normal use.

5. maintenance methods

1, regularly check the water pipe, flange and pipe connection, if damaged or loose, timely replacement and repair.

2, every certain time for a cleaning, remove dirt and blockage, to ensure smooth.

3. In use, if the water pump is found to have poor drainage or water leakage, check the water pipe interface or valve and other parts in time to eliminate the fault as soon as possible.

4. When not in use for a long time, close the valve and drain the water in the water pipe to avoid pumping with the pump.

5. The service life of multi-stage centrifugal pumps is generally about 5 years. After the service life expires, they should be replaced in time to avoid malfunctions and affect normal use.
