Fire automatic constant pressure water supply equipment. Fire pumps, fire pumps models, fire pump price, fire automatic fire pump manufacturer constant pressure water supply equipment to automate the measurement instruments constitute the main control unit, the water supply system for the automatic control device by way of setting a constant water supply, fire pump Group Scope For all types of fire hydrants, automatic sprinkler, water curtain, fire service. Second, the performance characteristics of a fire pump, fire pump frequency operation, the regulator constant pressure pump control, fully automatic operation. 2, automatic inspection cycle, manual inspection at any time. 3, with automatic, manual, remote operation, sound and light signals and fire alarm and control center linkage functions. 4, compact structure, easy installation, small footprint, low investment. 5, using advanced programming techniques, pressure constant, reliable operation. Third, the fire pump technical indicators: 1, fire water supply: 10 ~ 100L / s 2, Fire Water pressure: 30 ~ 160m 3, power supply: three-phase four-wire ~ 380V, ~ 220V Fire Pump Fire water supply equipment principle intelligent pipe Relay boost (no vacuum) device can be set to the user based on user needs water pressure, water pressure if the pipe above the set pressure, the pump unit is shut down, the water pipe line through direct user water supply. When the municipal pipe network water pressure below the set pressure, the device automatically enters Relay boost job status, the unit through pressure sensors, pumps and constant frequency control cabinet closed-loop control system, along with changes in water, and constantly adjust the pump speed and put into operation a number of pump units, in order to maintain a constant water pressure. Flow regulator is a sealed container in the water supply network to meet the water supply requirements, this device as a buffer device with frequency conversion water supply pipe network between devices to eliminate the pulsation of the pump unit on the pipe network. When inadequate water supply pipe network capacity, as a flow regulating device to alleviate the lack of flow of water pipe network's peak. Network protection installed on the flow regulator, when the tank pressure than the outside pressure is high, the pipe network protection off, the pump unit overlay existing municipal pipe network constant pressure water supply; when the tank pressure equilibrium with the outside world, network protection opens with the outside world, to avoid the formation of negative pressure to ensure the safety and other municipal pipe network users normal water supply. When the water supply pipe network without water, the device automatically stops running, restore the water supply pipe network automatically. When a power outage, water pump stopped working, through the connecting pipe water directly into the user network, incoming calls automatically turn the unit back to normal water supply.
