Integrated above ground box pump and above ground stainless steel fire booster water supply pump station

Description :

　　Design Specification for Integrated Fire Boosting Water Supply Pump Station with Above Ground Box Pump: The box pump integrated stabilizing pump stabilizing pump should be a centrifugal pump and should comply with the following regulations: 1. Single suction single-stage or single suction multi-stage centrifugal pumps should be used; The material of the main components such as the pump casing and impeller should be stainless steel. 2、 The design flow rate of the stabilizing pump should comply with the following regulations: 1. The design flow rate of the stabilizing pump should not be less than the normal leakage rate of the fire water supply system pipeline network and the automatic start-up flow rate of the system; The normal leakage rate of the fire water supply system pipeline network should be determined based on the pipeline material, interface form, etc. When there is no data on the leakage rate of the pipeline network, the design flow rate of the stabilizing pump should be calculated at 1% to 3% of the design flow rate of the fire water supply system, and should not be less than 1L/s; The automatic starting flow rate of alarm valves, pressure switches, etc. used in the fire water supply system should be determined according to the product. 3、 The design pressure of the stabilizing pump for the fire pressure boosting and stabilizing water supply equipment should meet the following requirements: 1. The design pressure of the stabilizing pump should meet the requirements of automatic system start-up and pipeline filling with water; The design pressure of the pressure stabilizing pump should maintain that the pressure at the automatic pump start pressure setting point of the system is greater than the automatic pump start pressure value set by the system in the quasi working state, and the added value should be 0.07MPa~0.10MPa. The design pressure of the integrated pressure stabilizing pump of the drawing box pump should maintain that the static water pressure of the water fire extinguishing facility at the unfavorable point of the system in the quasi working state should be greater than 0.15MPa. 4、 The temporary high-pressure fire water supply system with a stabilizing pump should be equipped with technical measures to prevent frequent start and stop of the stabilizing pump. When using an air pressure water tank, its regulating volume should be calculated and determined based on the number of pump starts of the stabilizing pump not exceeding 15 times/h, but the effective water storage volume should not be less than 150L. Fifth, the stabilizing pump suction pipe should be equipped with a rising stem gate valve, and the stabilizing pump outlet pipe should be equipped with a silencing check valve and a rising stem gate valve. 6、 The stabilizing pump should be equipped with a backup pump.
