Common Problems & Solutions

1. Pump No Pressure or Insufficient Pressure

● Problem: The Air Cooled Hydraulic Ceramic Piston Pump For Filter Press runs normally but cannot build up pressure, or the pressure is too low to feed the filter press.
● Solution: Check hydraulic oil level and oil quality; replace deteriorated hydraulic oil in time. Inspect hydraulic valve block for jamming and clean internal impurities. Confirm ceramic plunger and sealing ring are not severely worn, replace damaged seals and wearing parts.

2. Unstable Pressure & Pressure Fluctuation

● Problem: Working pressure rises and falls frequently, affecting filter press feeding effect.
● Solution: Check whether the pipeline is blocked or leaking. Adjust PLC control parameters to keep stable reversing frequency. Check air cooling system for poor heat dissipation causing hydraulic oil overheating; clean cooling dust and ensure normal air circulation.

3. Pump Runs No Slurry Discharge

● Problem: The equipment operates normally, but no sludge or slurry is delivered.
● Solution: Check the inlet pipeline for air leakage or blockage. Discharge air inside the pump body to avoid air lock. Clean sundries at the inlet to prevent material clogging, and check whether the steering of the motor is correct.

4. Excessive Running Noise & Vibration

● Problem: The pump produces loud noise and strong vibration during operation.
● Solution: Check anchor bolts for looseness and fasten all mounting parts. Inspect hydraulic station for abnormal noise caused by oil pump wear. Confirm plunger reciprocating operation is not stuck; adjust installation level to reduce mechanical vibration.

5. Poor Air Cooling & High Body Temperature

● Problem: Air cooling effect is poor, pump body and hydraulic oil temperature rise too fast.
● Solution: Clean dust, fiber and dirt on the air cooling fin surface regularly. Ensure the installation position is ventilated without shelter. Avoid long-term full-load continuous operation unreasonably; check cooling fan for damage and replace it if failed.

6. Short Service Life of Sealing Parts

● Problem: Sealing rings and wearing parts are easy to aging and damage with short replacement cycle.
● Solution: Use original standard sealing accessories. Avoid conveying over-concentration slurry and large granular impurities. Keep hydraulic oil clean and prevent impurities from abrading seals.

7. Automatic Reversing Failure

● Problem: The Air Cooled Hydraulic Ceramic Piston Pump For Filter Press cannot reverse automatically, runs in one direction or stops suddenly.
● Solution: Check PLC control circuit and sensor line for loose contact. Reset control parameters; clean electromagnetic valve core for jamming. If electrical parts are damaged, replace matching control components in time.
