    What if the water output of single-stage centrifugal water pump equipment is insufficient

    in Health

    When using single-stage centrifugal water pump equipment, the water output is insufficient occasionally. Many people don't know the reason, so they can't find a solution Due to the vortex generated in the pool and the air sucked into the pump body by the self-priming centrifugal pump, the water output of the pump is insufficient. In case of this phenomenon, the submerged depth of the inlet pipe can be increased, or other measures to prevent vortex can be taken. The impeller leakage reducing ring of single-stage centrifugal pump is worn too much, resulting in insufficient water output of the pump. Only replace the leakage reducing ring or replace the impeller if necessary. Because the speed of the water pump is too low, for example, the speed of the water pump is required to be 2900r / min, while the motor speed of some users is only 1450r / min. for example, some users of common vertical centrifugal pump products use frequency conversion control. Because the frequency is adjusted too low, the water volume will be reduced accordingly. The solution is to make the water pump power machine reach the standard speed Because there is air in the water inlet pipe of various pumps, the solution is to reinstall the water inlet pipe of the pump to make the water inlet pipe horizontal or inclined downward. If the impeller of the water pump is seriously damaged due to cavitation or corrosion, use a new impeller or corrosion-resistant impeller. The opening of the bottom valve of the water pump is too small or the bottom valve, water pump and pipeline are blocked by sundries. At this time, check and eliminate them one by one If the pump operates for a long time, it is likely that the pump flow will be reduced due to the excessive clearance of the mouth ring, but the change of this amount should not be reduced suddenly, but should be a slow process. If the pump has not been overhauled for a long time, the flow will be reduced but the operation is stable, which is likely to be caused by the wear of the mouth ring, which must be disassembled for inspection. The solution is to reuse the new pump body mouth ring and impeller mouth ring

    I'm not a little piece looking on the net for articles that could banter with me and this is one in every one of them. This is a development that unequivocally costs up through thought-controlled battles. The entire article is doubtlessly overpowering and purposely made.
