Jockey pumps play a crucial role in maintaining pressure within a fire pump system, preventing unnecessary starts of the main fire pump. However, they can experience issues that affect system performance. Identifying and resolving these problems promptly ensures reliable fire protection.
1. Jockey Pump Running Continuously
Causes:
- A leak in the fire protection system
- Incorrect pressure switch settings
- Faulty check valve or pressure relief valve
Solutions:
- Inspect for leaks in pipes and fittings
- Adjust pressure switch settings to match system requirements
- Check and replace faulty valves if necessary
2. Jockey Pump Not Starting
Causes:
- Electrical supply issues
- Faulty pressure switch or control panel
- Motor failure
Solutions:
- Check power supply, breakers, and wiring connections
- Test and replace a faulty pressure switch if needed
- Inspect the motor for overheating or mechanical failure
3. Pressure Loss in the System
Causes:
- Pipe leaks or damaged fittings
- Air trapped in the system
- Incorrect pressure settings
Solutions:
- Conduct a thorough system leak test
- Bleed air from the system to ensure smooth operation
- Verify and reset pressure switch settings
4. Excessive Noise or Vibration
Causes:
- Misalignment of pump and motor
- Loose components
- Worn bearings or cavitation
Solutions:
- Align the pump and motor correctly
- Tighten any loose fittings or mounting bolts
- Replace worn bearings and check for cavitation issues
5. Overheating Jockey Pump
Causes:
- Blocked cooling vents
- Overloaded motor
- Insufficient lubrication
Solutions:
- Clean cooling vents and ensure proper airflow
- Verify motor load and check for electrical issues
- Lubricate moving parts according to manufacturer guidelines
Final Thoughts
Regular maintenance and timely troubleshooting of jockey pumps are essential for ensuring the reliability of fire protection systems. By addressing these common issues, you can prevent system failures and maintain optimal performance.
