Pressure stabilizing pump is a type of fire pump used in automatic sprinkler fire extinguishing systems. The pressure of the fire hydrant water supply system is stable, and the system pressure is always at the required pressure state. Once the nozzle or fire hydrant discharges water, the water flows out to meet the requirements of fire water and water pressure Although pressure regulating pumps and booster pumps are booster facilities, voltage regulators do not discharge during the operation of sprinkler irrigation machines and hose pumps. Booster pumps discharge water when nozzles and fire hydrants are working, and the pressure of fire water is insufficient, requiring an increase in water pressure

Booster pumps discharge water when nozzles and fire hydrants are working, and the pressure of fire water is insufficient, requiring an increase in water pressure
As long as the booster pump is started, the main fire pump is subsequently activated, and the effect of the booster pump is not very urgent and necessary Pressure regulator is different from booster pump. Pump is used to maintain the working pressure of the sprinkler system under the conditions required by the fire hydrant system. Once the flow rate reaches the required water pressure, it meets the requirements of fire water and water Its function is very obvious, so the standard for booster pumps is essentially a stabilizing pump, especially for automatic sprinkler systems The size of stable pump flow is determined by various factors, among which the main factors are:
(1) When using an automatic sprinkler fire extinguishing system, the type of system should take into account the water volume of the nozzles; When used in a fire hydrant system, fire hydrants should be considered
(2) When setting the support for the pressure water tank, the flow rate of the stabilizing pump should be calculated based on the water volume of the nozzle or fire hydrant A complete pressure tank will be formed, and the system pressure will be ensured by the air pressure tank to ensure the amount of water added. The pump flow rate regulation voltage needs to meet the requirements of the flow pressure tank, and the pump flow rate should consider the adjustment factor of the pressure water tank volume for voltage stability At this point, the stable pressure pump flow rate should be calculated based on the total volume of air and water in the tank and the amount of water in the tank When the average pressure of the pipeline network is not less than the average pressure of the pipeline network, the flow rate of the water pump should be 1.2 times the maximum flow rate of the pipeline network No pressure water tank must be configured, but there is no pressure water tank The use of a pressure water tank can reduce the frequent start-up of the stabilizing pump and better ensure the stable operation of the system However, it is necessary to increase the cost of the pressure water tank Generally speaking, the volume of air pressure should not be too large, and the volume should be less than 50L
(3) The system is equipped with a quasi steady pressure water supply system, featuring a stable pressure pump and indoor and outdoor areas The indoor quasi high pressure water supply system uses steel pipes for pipelines and threaded, flanged, or welded connections for interfaces. The leakage of the pipeline system mainly occurs at the sealing parts of the water pump, and its quantity is relatively limited The indoor and outdoor high-pressure water supply system, due to the use of iron pipes for pipelines and socket connections for outdoor interfaces, is sealed with rubber rings. The pipeline network is large, and the interface range accounts for a considerable proportion of the entire leakage volume After the pipeline is built, the soil is repaired, and sometimes the interface is reinforced with suspicious soil mixture Even if there is leakage, it is difficult to take remedial measures This indicates that when using water supply systems indoors or outdoors, the flow rate of the stabilizing pump should be sufficient
