1. Pump speed is too low: check the speed, improve the speed.
2. The system static head increase: check the liquid height and system pressure.
3. The loss of resistance to increase: check the pipeline and check valves and other obstacles.
4. The shell and impeller wear ring wear is too large: to replace or repair the wear ring and impeller.
5. Other parts of the liquid leakage: check the seal and other parts.
6. Pump impeller plug, wear and corrosion: cleaning, inspection, replacement.
Fluorine plastic centrifugal pump head is not enough reason and processing method
1. Inadequate irrigation pump (or pump gas is not discharged): re irrigation pump.
2. Pump steering is not: check the direction of rotation.
3. Pump speed is too low: check the speed, improve the speed.
4. Filter plug valve, check the filter, to eliminate debris.
5. Suction pipe leakage: check the suction side of the pipe connection and stuffing box sealing condition.
6. Pump impeller plug, wear and corrosion: cleaning, inspection, replacement.
7. Impeller mounted anti (double suction wheel): check the impeller.
8. Liquid density, viscosity and design conditions do not match: check the physical properties of liquids.
9. The operation of the traffic is too large: reduce the flow.
