Daily Maintenance
1. Regularly check the piston pump's seals and pipe connections for tightness. Tighten any loose parts immediately.
2. Monitor the piston pump's liquid level and maintain it within the specified range. A low liquid level can lead to unstable operation and increased noise.
3. Regularly clean the piston pump's surface to prevent dust and other impurities from entering the pump body and affecting its normal operation.
Troubleshooting
1. No pump pressure or unstable pressure
This may be due to air bubbles at the pump's suction inlet. Check for a leaky suction inlet, air leaks in the pipes, and sufficient inlet pressure.
2. Reduced pump displacement or no pump output
This may be due to a clogged inlet filter, requiring cleaning or replacement. It could also be due to damaged seals, requiring replacement.
Precautions
1. When using a piston pump, pay attention to its rated pressure and displacement; do not exceed its operating range.
2. When replacing seals, select appropriate seals and follow the prescribed operating procedures.
3. When using a piston pump, pay attention to safety and avoid dangerous situations such as pump body rupture or hydraulic line rupture.
