建筑消防给水稳压系统（Building fire water supply stabilizing system） Building fire water supply stabilizing system 0 Introduction The water supply system is divided into two parts: regulated pump, direct voltage regulating mode and regulated pump. The pump is divided into direct voltage regulator pump with high water tank and pump regulator with voltage regulator two underground fire pool directly; pump and pressure tank system is divided into high water pressure water supply device with voltage and pressure water supply device to replace the high water pressure stable two. 1 constant pressure pump with high water tank voltage regulation mode When the system works, the constant pressure pump pumps water from the high water tank and then enters the system to extinguish the fire. When the pressure stabilizing pump stops running or overhauling, the water supply system is regulated by a high-level water tank, so that the fire hydrant water supply system with little fire risk and small system scale can adopt this mode. 2 constant pressure pump, with the underground pool direct voltage regulation Constant pressure pump with the main pump, water from the pool to the system to maintain the pressure system, known as constant pressure or stable high pressure, quasi high pressure system, is not located high fire water tank system. Pump steady high pressure fire water supply system must be in peacetime to maintain the running state, to maintain the pressure of the pipe network, at the time of the fire, still should be able to run for a period of time, until the main fire pump start so far, according to the main and standby pump pump set. Due to the need for constant pressure pump has been running, waste of energy, but also for the long-term pressure pump in the working state, the service life has a high demand, so the project has not been used. 3 high water tank with pneumatic water supply device voltage regulation mode The air pressure tank according to the small capacity requirements se
