    The design requirements of the flow and pressure of the fire stabilizing pump

       Although the fire fighting jockey pump is rarely seen, it is beside you. It is an indispensable machine in the process of fire protection and water rescue. When there is a fire in a relatively high building at ordinary times, sometimes the height of the fire water tank is not designed to meet the high water pressure required for fire extinguishing, then a pressure-stabilizing pump should be used. The purpose of the stabilizing pump is to stabilize the most unfavourable water pressure point when extinguishing the fire.
       When designing the water flow of the fire fighting jockey pump, it must be larger than the normal water leakage of the fire water supply system and the water flow of the system itself. Moreover, the design of the alarm system and valve of the regulator pump should be set according to different products. And the pressure of the fire pump is also very important. Its pressure should meet the working conditions of the system itself, and it should also meet the pressure requirements of the fire-extinguishing pipeline filled with water.
       The pressure of this machine is designed to be greater than the pressure when the fire water supply system starts the fire pump when it is working, and the pressure increase value should be between 0.07MPa and 0.10MPa. When the fire water supply system performs water extinguishing at a point that cannot be reached, the pressure of the fire pressure stabilizer pump when entering the water is greater than 0.15MPa.
      The requirement for the start of the stabilizing pump is when the machine has reached the set self-starting pressure. And when the machine has reached the pressure that the fire water supply system needs to stop, the machine will automatically stop working. Therefore, specific settings must be made when designing the water pressure, otherwise the machine will easily break down.
      When the main fire pump can start itself, and has met the requirements for automatic system start, the regulated pump should stop working immediately. And when the machine is working normally, the number of startups per hour cannot exceed fifteen times. After the system's water supply has stabilized, the regulator pump should no longer start or stop frequently.
    The function of the fire fighting jockey pump is very important. When a building is on fire, it can play the biggest role, can start automatically, and allow the maximum pressure to be sprayed where the high-pressure water gun cannot reach before, which It has played a great role in maintaining the safety of our lives and property.
