.The difference between fire booster pump and pressure stabilizing pump
There are significant differences between fire booster pumps and pressure stabilizing pumps in many aspects. The following is a detailed analysis of the differences between the two:
1. Definition and use
Fire booster pump: The fire booster pump is mainly used to increase fire water pressure and is an important part of the fire protection system. It can ensure that fire-fighting water can meet fire-extinguishing needs by increasing water pressure when a fire occurs. The main function of the booster pump is to automatically start to increase the water pressure when the sprinkler heads and fire hydrants have discharged water but the water pressure for firefighting is insufficient to ensure an effective supply of firefighting water.
Stabilizing pump: Stabilizing pump is a type of fire pump, mainly used to stabilize the pressure of automatic sprinkler systems and fire hydrant water supply systems. It can keep the system water pressure in the required state. Once the sprinkler head or fire hydrant discharges water, the amount and pressure of water required for firefighting water can be discharged. The pressure stabilizing pump starts running when there is no flow from the sprinkler head and fire hydrant to ensure the stability of the system pressure.
2. Working principle
Fire booster pump: The working principle of the booster pump is to drive the impeller to rotate through the motor, thereby making the water flow and increasing the water pressure. In the fire protection system, when the pipe network pressure is lower than the set value, the booster pump will automatically start to increase the pipe network pressure to the set value.
Stabilizing pump: The stabilizing pump achieves the purpose of stabilizing the output water pressure by adjusting the valve at the outlet. It can automatically adjust the output water pressure according to system needs to ensure the stability and reliability of system pressure.
3. Application scenarios
Fire booster pump: Mainly used in fire protection systems, urban construction, industrial production and other fields, especially in situations where a large amount of water pressure needs to be provided in a short period of time.
Stabilizer pump: In addition to being used in fire protection systems, pressure stabilizer pumps are also widely used in hydraulic systems, industrial production, civil water supply and other fields. Its main function is to stabilize the output water pressure and ensure the normal operation of the hydraulic system.
4. Performance characteristics
Fire booster pump: The advantage is that it can provide a large amount of water pressure in a short time to meet the needs of the fire protection system. However, its disadvantage is that it cannot work once there is a power outage, so emergency measures such as backup power supply need to be considered during design.
Stabilizing pump: The advantage is that it can stabilize the output water pressure and ensure the stability and reliability of the system pressure. However, its output water pressure is relatively low and is not suitable for occasions that require a large amount of water pressure.
5. Start and stop conditions
Fire booster pump: When the pressure of the fire pipe network is lower than the set value, the booster pump will automatically start to increase the water pressure; when the pressure is higher than the set value, the booster pump will automatically stop running.
Stabilizing pump: The starting and stopping conditions of the stabilizing pump are related to the pressure state of the system. When the system pressure drops to the start-up pressure of the stabilizer pump, the stabilizer pump will start to stabilize the system pressure; when the system pressure reaches the pump-stop pressure, the stabilizer pump will automatically stop running.
