The fire fighting jockey pump is a kind of fire-fighting pump. It is used to stabilize the pressure of the automatic sprinkler system and the fire hydrant water supply system, so that the water pressure of the system is always in the required pressure state. Once the nozzle or fire hydrant is out of water, it can flow out to meet the requirements of fire-fighting water. The amount of water and water pressure. It is started and stopped by the contact pressure gauge installed on the pipe network. After setting the pressure value, it automatically fills the pipe network and automatically stops after reaching the set pressure value. It does not need to be interlocked with the fire pump. Voltage regulation. There is also a device called a fire water supply pump. What is the relationship between them?
1. The fire water supply pump can be manually started in the pump room. It can be started directly in the automatic state with the control cabinet, or it can be started directly in the button inside each fire hydrant.
The fire water supply pump refers to a special fire pump or a common clean water pump that meets the national standard "fire pump performance requirements and test methods" GB 6245. Fire water supplied by most fire water sources requires a fire pump to pressurize to meet the water pressure and water requirements during fire fighting.
2. The fire fighting jockey pump is generally installed on the top floor of the high-rise building. It supplements the water pressure of the fire-fighting pipe network on the top floor. After setting the pressure value, it automatically replenishes the pipe network and automatically stops after reaching the set pressure value. It is usually installed when the height of the fire floor and the roof of the floor is less than 5 meters.
There is an original on the fire fighting jockey pump called: differential pressure controller (also called pressure controller), which is adjustable. Set a certain pressure value on the differential pressure controller, such as 0.2MPA, then when the pipe network pressure is lower than 0.2MPA, the steady pressure pump starts automatically, and the pressure is applied to the pipe network. When the pressure of the pipe network reaches the set 0.2MPA When the regulator pump stops automatically.
The fire fighting jockey pump does not work continuously. The frequency of starting depends on the pressure loss of the pipe network.
