Operational control process: According to calculations obtained the fire hydrant system or sprinkler pressure extinguishing system required the most negative point P1 as a pressure tank of inflation pressure. Selected by calculating the pressure tank specifications ab values ??obtained P2, and set P3 = P2 + (0.02-0.03), P4 = P3 + (0.06-0.06). Usually subject to leakage and other relief piping system, the regulator constantly pumps water regulator, in P3, P4 (start = stop) repeatedly run, if there is a fire, a lot of water piping systems, pressure drop caused by P3 (P3- P4), when reduced to P2, an alarm signal, automatically start the fire main pump immediately after the main fire pump is activated, the regulator pump automatically stops after the end of the fire, cabinet and automatically resume control regulator pump. After the user has a fire control center to prevent false alarms, the alarm signal will be transmitted to the fire control center, the center of the integrated signal processing, cabinet return again to start the fire main pump signal. ◆ innovative features: 1, no need to build pumping stations, saving space; 2, silent type fire pump, run without noise, energy saving and environmental protection; 3, fire pumps have been installed in the tank, with a unique silencer antifreeze function; 4 When equipment maintenance, fire water tank without emissions, and energy conservation; 5, has a water tank alarm, fault alarm and automatic switch, fire linkage function; 6, the system uses the new standard production system using the PLC programming, have inspection log data output port, the internal data storage and other functions. Equipment Overview: WYDXBF series fire booster regulator water supply equipment (pumps smart box integration) is based on the Ministry of Public Security GB27898.1-27898.3-2011 "fire pressure water supply equipment performance requirements and test methods" and Sue S / T08-2009 standard New Fire-specific design of fixed fire extinguishing equipment. Fire is mainly made of stainless steel water tank, fire booster pump regulator, pressure tank, control cabinets, instrument, diffuser, pipe fittings and other components, widely used in multi-storey and high-rise construction, there is a fire hydrant booster regulator design requirements water supply systems and sprinkler systems and other fire water system. ◆ Features: 1, usually run by a pump regulator, when the fire main fire pump start, while the regulator pump stops running. The implementation of the above process is automatically converted by the electronic control system, this unit set up two or more regulated pump spare each other, take turns running. 2, usually by regulated water pump, the entire fire control network at high pressure, while the pressure of the fire water storage tank fire beginning to solve the latency problem for a long time extinguishing the fire water present in the system. 3, with automatic, manual, fire linkage, remote operation function, protection function, safe and reliable operation. ◆ Function: 1, so that the most negative point fire water system pressure required to always keep the fire; 2, in the pressure tank is always there 30 seconds fire water storage, the use of pressure tank set P1, P2, P3, P4 operating pressure, control pump operating conditions, to the supercharger and regulation functions. P1 is the most negative point of the fire required pressure (MPa) P2 for the fire pump starting pressure (MPa) P3 pump starting pressure for the regulator (MPa) P4 to stop the pump regulator pump pressure (MPa)
