The inspection of horizontal multistage centrifugal pump is an important step to ensure its normal operation. Regular inspection of the appearance of the pump, mechanical seals, pipe valves, axial clearance and shaft seals, as well as performance testing, can help early detection and resolution of potential problems, to ensure efficient operation and long life of the pump.

Horizontal multistage centrifugal pump is a kind of commonly used industrial equipment, used to transport liquid and supply to industrial systems. In order to ensure the normal operation of the pump and extend its life, it is very important to conduct regular inspections. The following Hunan Sanchang Pump will introduce some methods and steps on how to check the horizontal multistage centrifugal pump.

First, make sure that the pump has stopped running and disconnected the power supply before performing any inspections. This is to avoid any risk of accidental injury and electric shock.

Second, check the appearance of the pump and mechanical seal. Carefully observe the pump housing and interface for obvious cracks, corrosion or leakage. At the same time, check whether the mechanical seal of the pump is operating normally to ensure that there is no leakage at the seal.

Next, check the pump inlet and outlet pipes and valves. Clean the inlet filter to ensure that there are no blockages to ensure that the pump can suck liquid normally. Check outlet piping and valves to make sure they are not loose, damaged or leaking.

Then, check the axial play and shaft seal of the pump. Shake the impeller of the pump by hand and check for abnormal looseness or jam. At the same time, check whether there is a leak at the shaft seal, and the seal needs to be replaced in time to prevent further damage.

Finally, the performance test of the pump is carried out. Test the performance parameters of the pump, such as flow, head and efficiency, by using appropriate instruments and equipment. According to the test results, evaluate the working state of the pump, and make necessary adjustments and maintenance.
