Jockey pumps play a crucial role in fire protection systems, especially in systems with extensive outdoor piping. Here's how they are utilized:
### Purpose of Jockey Pumps
1. **Maintain System Pressure:** Jockey pumps are designed to maintain a constant pressure in the fire protection system’s piping network. They compensate for small pressure drops caused by minor leaks, thermal expansion, or other factors. This ensures the system is always pressurized and ready to deliver water immediately in the event of a fire.
2. **Prevent False Alarms:** By keeping the pressure stable, jockey pumps prevent the main fire pump from being activated unnecessarily. This helps avoid false alarms and unnecessary wear and tear on the main pump, ensuring that it is only activated during an actual fire event.
### Specific Utilization in Extensive Outdoor Piping
1. **Compensate for Pressure Loss:** In systems with extensive outdoor piping, there is a higher chance of pressure loss due to long pipe runs, elevation changes, and potential minor leaks. Jockey pumps regularly run to compensate for these losses, maintaining the required system pressure.
2. **Minimize Pipe Damage:** Outdoor piping is more exposed to environmental factors such as temperature changes, which can cause expansion and contraction. Jockey pumps help minimize the risk of pipe damage by keeping pressure consistent and reducing the strain on the piping network.
3. **Avoid Water Hammer:** By gradually restoring pressure when minor drops occur, jockey pumps help prevent water hammer, which can damage pipes and fittings, especially in long outdoor runs.
In summary, jockey pumps are essential in fire protection systems with extensive outdoor piping to ensure the system remains pressurized, prevent unnecessary operation of the main fire pump, and protect the integrity of the piping network.
