Magnetic pump does not feed the reason

　　The reason why the magnetic pump does not feed may involve a number of aspects, the following are some common reasons and the corresponding solutions:

　　First, the pump body and impeller problems

　　There is gas or impurity inside the pump body:

　　Reason: magnetic pump restarted after a long period of downtime, the gas accumulated in the pipeline will hinder the normal operation of the fluid; or the pump body is clogged with internal impurities.

　　Solution: You need to put the pump upside down and make the pump impeller rotate a few times to discharge the air and impurities inside the pump.

　　Impeller damaged or clogged:

　　Reason: The impeller of the magnetic pump is the key component connecting the rotor and the motor shaft, if the impeller exists in the case of wear, breakage or clogging, it will affect the normal operation of the pump.

　　Solution: It is necessary to clean the impeller and the pump body, check whether there is obvious wear or breakage etc. of the impeller, if so, it is necessary to replace the impeller.

　　Second, the import and valve problems

　　The inlet valve is not opened or is not opened completely:

　　CAUSE: If the inlet valve is not opened properly, liquid will not enter the pump body smoothly.

　　SOLUTION: Check that the inlet valve is open and make sure it is fully open.

　　Inlet valve failed:

　　CAUSE: The inlet valve of the magnetic pump is a key component in controlling the inlet and outlet of the fluid. If the inlet valve fails or is stuck, the normal operation of the pump will be hindered.

　　Solution: It is necessary to check whether the inlet valve opens normally or whether it is contaminated, and replace the inlet valve if necessary.

　　Third, piping problems

　　Piping obstruction:

　　Reason: magnetic pump conveying fluid through the pipeline, if there is foreign matter, scale or crystallization and other substances in the pipeline, it will block the pipeline, resulting in the fluid can not run normally.

　　Solution: The pipeline needs to be cleaned to remove the foreign matter and scale in the pipeline.

　　Fourth, the pump inlet and pressure problems

　　Pump inlet blockage:

　　Reason: there is a blockage in the liquid inlet pipe or pump body inlet, may be due to impurities in the pipe, foreign matter or sediment accumulation.

　　Solution: Clean up the blockage in the pipeline or pump body inlet.

　　Insufficient inlet pressure:

　　CAUSE: The inlet pressure of the pump is too low, which will result in the liquid not being able to enter the pump smoothly.

　　Solution: Increase the pump's inlet pressure, specific methods include adjusting the height of the inlet pipe, installing inlet pressure booster.

　　V. Other factors

　　Pump reversal:

　　Reason: If the pump steering is not correct, it will also lead to the phenomenon of not feeding.

　　Solution: Adjust the pump steering to ensure that the pump rotates in the correct direction.

　　Suction height is too high:

　　Reason: If the suction height of the pump is too high, exceeding the suction capacity of the pump, it will also lead to not feeding.

　　Solution: Reduce the installation height of the pump to ensure that it is within the suction range of the pump.

　　The viscosity of the liquid is too large:

　　CAUSE: If the viscosity of the liquid is too large, it will lead to the pump's rotor not being able to rotate properly, thus not being able to suction the liquid.

　　Solution: Choose the liquid with suitable viscosity or reduce the viscosity by heating the liquid.

　　To summarize, the reasons why the magnetic pump does not feed may involve the pump body, impeller, inlet and valve, piping, pump inlet and pressure and other aspects. When troubleshooting and solving these problems, it is necessary to carefully check and test each component and link to find the problem and take appropriate solutions. If the problem is complex or difficult to solve, it is recommended to contact a professional technician or manufacturer for assistance.
