The Reason of Grout Pump Insufficient Pressure

Insufficient grouting pump pressure may be caused by the following reasons:

1 .Insufficient injection material: This may cause the grouting machine to fail to generate sufficient pressure. Check the inlet for sufficient material and increase the injection material promptly.

2. Worn or damaged grouting pump seals: This may cause leakage, resulting in insufficient pressure. Inspect the seals and replace them if worn or damaged.

3. Faulty pressure regulating or control valves: This may also cause insufficient pressure. Inspect and repair the pressure regulating and control valves to ensure proper functioning.

4. Worn or damaged internal parts of the grouting pump: This may also affect its proper functioning. If the problem persists, the hydraulic grouting pump may need to be disassembled and repaired, and worn or damaged parts may need to be replaced.

5. Insufficient grouting liquid: Insufficient grouting liquid can also cause insufficient grouting pressure. In this case, check the grouting material and ensure that it meets the required quality.

6. Poor grouting orifices: Poor grouting orifices can also cause insufficient grouting pressure. In this case, inspect the grouting orifices for wear or blockage and clean or replace them promptly.

7. Air ingress: Air ingress is another factor that can cause insufficient grouting pressure. In this case, check the grouting piping for leaks or looseness, and perform repairs and adjustments promptly.

8. Insufficient system air pressure: Check the system air pressure to see if it's normal, and perform repairs and adjustments as needed.

9. Severe internal wear of the pump: Check the pump for wear and tear, and replace the pump.

10. Foreign matter inside the pump: This can cause pump failure. Check the pump for foreign matter and clean the pump components.

The above are possible causes of insufficient grouting pump pressure. If all components are normal, consider contacting the manufacturer or a professional technician for further inspection and repair.
