The diesel engine fire pump can form an automatic water fire water supply system with electric pumps and jockey pumps, and can be linked with the fire control center.
When the diesel engine fire pump set receives the starting command, if the mains power is cut off, the automatic control cabinet of the diesel engine will immediately send a start signal to the starting motor of the pump set, start the motor, start the diesel engine at idle speed, and then gradually adjust the throttle to accelerate the diesel engine until Rated speed. The control system will automatically monitor the operation of the diesel engine, such as the oil pressure, oil temperature, speed of the diesel engine, outlet pressure of the water pump, etc., and determine whether the diesel engine starts normally through automatic monitoring. If the start fails, the control system will send a restart signal, and if the three starts fail, the automatic control system will send a failure alarm. When the diesel engine fire pump set receives a signal that the pressure of the pipe network is restored or the mains power is restored to normal, the pump set will quickly slow down and stop automatically after monitoring the idle position for a period of time.

Containerized fire pump system which consist of electric fire pump, diesel engine fire pump and jockey pump, with booster pump system

In cold climates, jockey pumps must be designed and installed with specific considerations to prevent freezing and ensure reliable operation. This includes using heat tracing or insulation on piping and pump components exposed to low temperatures to prevent ice formation that could block water flow. Jockey pumps may also be housed in heated enclosures or indoor pump rooms to maintain a consistent temperature around the equipment. Additionally, the selection of antifreeze solutions or special materials resistant to cold temperatures can help protect the pump from damage. Regular monitoring and maintenance are also essential to ensure that the jockey pump remains operational and that the fire protection system is always ready to respond, even in harsh winter conditions.

Safety Valve plays a safety protection role in the system. When the system pressure exceeds the prescribed value, the safety valve opens, and a part of the gas/fluid in the system is discharged into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.
Pressure Tank: Water is a non-compressible medium. Generally speaking, the pressure drop of fire-fighting pipe network is normal. However, the pressure drop is very slow, the total loss of water in the pipe network isnot large, and the frequent change of pressure in the pipe network leads to frequent start-up and shutdown of pumps. Especially when the power of equipment is high, it will cause great impact on pressure sensors, relaysand motors, thus affecting the performance and life whole equipment. Therefore, it is necessary to choose the right volume of the pressure tank.
