Abstract
A fire-fighting stable high-pressure frequency-conversion water supply equipment comprises a stabilized pressure pump, a fire pool, a fire pump, an electrical cabinet and a fire let-off pipe. The stabilized pressure pump and the fire pump are connected between the fire pool and the fire let-off pipe in parallel; a surge tank and a liquid flow controller are positioned on the fire let-off pipe; a transmissible pressure gauge is positioned on the surge tank; the upper fire let-off pipes of the front end and the back end of the liquid flow controller are respectively connected into the fire pool via a return pipe and a pressure release pipe; a fluid level controller, the stabilized pressure pump, the fire pump, the transmissible pressure gauge and an electric valve are arranged on the fire pool; and the liquid flow controller and the fluid level controller are connected with the electrical cabinet via the lead. The utility model has the advantages of simple and compact structure, simple pipeline and easy installation. The equipment can meet the requirements of water pressure and water flow of corresponding fire water at the initial stage and the developing stage of the fire, not only in condition of prepare operating but also in firefighting; the firefighting success ratio is higher than the interim high pressure water supply system; and the stabilized pressure device is added only, which is more economical than the normal high pressure water supply system.
Description
Technical field
The utility model relates to fire supply system, especially a kind of fire-fighting stable high-pressure frequency conversion waterworks.
Background technology
Existing fire supply system is divided into interim high pressure and normal high-pressure feed water system two classes.Interim high pressure fire fighting water supply system is when quasi-operating status, because the hydraulic pressure and the flow of fire demand water can not meet the demands fully, in case the condition of a fire takes place, can not be effectively, stamp out a fire in time; And normal high pressure fire fighting water supply system cost of investment is big, operating cost is high.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, low fire-fighting stable high-pressure frequency conversion waterworks of investment operating cost.
Fire-fighting stable high-pressure frequency conversion waterworks of the present utility model comprise gate valve, check-valves, stabilized pressure pump, fire cistern, fire pump, electrical control cubicles, the fire-fighting outlet pipe, stabilized pressure pump and fire pump and be connected in fire cistern and the fire-fighting outlet pipe between, stabilized pressure pump, the fire-fighting delivery side of pump is all installed gate valve and check-valves, vacuum tank and liquid flowing controller also are housed on the fire-fighting outlet pipe, vacuum tank is provided with the teletransmission Pressure gauge, before the liquid flowing controller, pass through return pipe respectively on the fire-fighting outlet pipe of rear end, relief tube inserts fire cistern, motor-driven valve is housed on the return pipe, safety relief valve is housed on the relief tube, fire cistern is provided with fluid level controller, stabilized pressure pump, fire pump, the teletransmission Pressure gauge, motor-driven valve, liquid flowing controller and fluid level controller all link to each other with electrical control cubicles by lead.
Fire-fighting stable high-pressure frequency conversion waterworks operation principle of the present utility model is: stabilized pressure pump pressurizes the water of fire cistern after check-valves and gate valve are sent in fire-fighting outlet pipe and the vacuum tank, the function one of vacuum tank is for the force value of system stability and passes on pressure signal to give electrical control cubicles, the 2nd, deposit has the fire initial stage fire-fighting pressure water in 30 seconds in jar, at ordinary times by (1.1kw--3kw) frequency conversion of low power stabilized pressure pump or power frequency work operation.When fire alarm takes place, system has big water gaging to go out stream, the liquid flowing controller received signal reaches electrical control cubicles, and electrical control cubicles is sent instruction immediately, and fire pump starts the input disaster relief immediately, meanwhile, the fire water volume also descends rapidly in the vacuum tank, and when reducing to that the water level lower limit is held fully in fire-fighting and stabilized pressure pump when transferring power frequency work to and still can not replenish water level and descend, electrical control cubicles receives this signal also can send instruction immediately, the fire-fighting main pump also can start the input disaster relief immediately, and stabilized pressure pump quits work automatically.As long as there is fire alarm to take place, have at least two signals to reach control system, electrical control cubicles is sent the enabled instruction of fire-fighting main pump immediately, and main pump starts commitment disaster relief fire extinguishing task in 30 seconds.
Fire-fighting stable high-pressure frequency conversion waterworks of the present utility model have compactness simple for structure, pipeline is simple, characteristics easily are installed, (flow Q=1L/S is advisable by low power stabilized pressure pump at ordinary times, lift is looked depth of building and is set, power is between 1.1kw--3kw) frequency conversion or power frequency operation, the day-to-day operation expense seldom, energy savings, no matter it is when quasi-operating status and fire-fighting, can both satisfy the hydraulic pressure and the traffic requirement of corresponding fire demand water to fire initial stage and developing stage, the success rate of fire extinguishing is higher than interim high-pressure feed water system, and the facility that increases stable-pressure device just only, more than normal high pressure fire fighting water supply system economy many.
