What are the reasons for the insufficient water output of centrifugal water pumps?
1. Due to the formation of vortices in the water pool, the self priming centrifugal pump sucks air into the pump body, resulting in insufficient water output of the pump.
This phenomenon can increase the submergence depth of the inlet pipe or adopt other measures to prevent the formation of vortices.
2. Due to the presence of air in the inlet pipes of various water pumps, the solution is to reinstall the inlet pipes of the water pumps,
making them horizontal or inclined downwards.
3. The excessive wear of the leakage reducing ring on the impeller of the water pump results in insufficient water output.
Only by replacing the leakage reducing ring or replacing the impeller if necessary.
4. Due to the low rotational speed of the water pump, for example, the required rotational speed of the water pump is 2900r/min,
while some users only use a motor with a rotational speed of 1450r/min.
For example, some users of commonly used vertical centrifugal pump products use variable frequency control.
Due to the frequency being adjusted too low, the water volume will also decrease when the rotational speed is too low.
The solution is to make the water pump power machine reach the standard rotational speed.
5. If the impeller of the water pump is severely damaged due to cavitation or corrosion, replace it with a new impeller or a corrosion-resistant impeller.
If the opening of the bottom valve of the water pump is too small or if the bottom valve, water pump,
or pipeline is blocked by debris, it should be checked and eliminated one by one.
