What are the reasons for the low discharge pressure of the diesel pump in the tank area?
The normal outlet pressure is 2.5 MPa, but it’s only 2 MPa now
I’m not sure what kind of pump you’re using; just by looking at the pressure, it’s not possible to determine the cause. The following are some possible reasons for low pressure – you might find them useful. Reasons for low outlet pressure in centrifugal pumps or gear pumps: 1. Clogged inlet filter or blocked pipelines. 2. Blockage in the impeller’s flow channels, excessive clearance around the impeller’s mouth ring, or damaged impeller. 3. The motor of the centrifugal pump is running in reverse, or the speed of the variable-frequency motor is too low. 4. Low back pressure at the outlet, with excessive opening of bypass circuits or return paths. 5. Wear and tear on the rotor due to prolonged operation, excessive clearance between the rotor components, or large gaps at the rotor’s end faces
