The specific embodiment
Contrasting accompanying drawing below in conjunction with embodiment is elaborated to the utility model.
Embodiment 1:
The utility model by fire department pumper connection 1, relay water pump 7, electro connecting pressure gauge 8, spray main fire pump 13, air pressure tank 5, switch board 16 and respective one- way valve 2,9,14,15, gate valve 3,4,6,12,14, threeway 10 automatically, underground conservation pool 11 constitutes, fire department pumper connection 1 is supplied water by air pressure tank 5, and be serially connected with relay water pump 7, relay water pump 7 and the automatic outlet pipe that sprays main fire pump 13 all are connected in parallel in the indoor fire-fighting pipeline.
Embodiment 2:
The utility model by fire department pumper connection 1, relay water pump 7, electro connecting pressure gauge 8, spray main fire pump 13, air pressure tank 5, switch board 16 and respective one- way valve 2,9,14,15, gate valve 3,4,6,12,14, threeway 10 automatically, underground conservation pool 11 constitutes, fire department pumper connection 1 is supplied water by air pressure tank 5, and be serially connected with relay water pump 7, relay water pump 7 and the automatic outlet pipe that sprays main fire pump 13 all are connected in parallel in the indoor fire-fighting pipeline, have been arranged in parallel pressure-reducing valve 17 and magnetic valve 18 on relay water pump 7 penstocks.
The present embodiment operation principle is: the flow of (1) relay water pump, lift, power be with to spray main fire pump performance parameter automatically identical, i.e. the same model water pump assembly.If fire fighting truck has been on the scene when fire, connect fire department pumper connection after, must cause indoor fire-fighting pipe-line system superpressure.For this reason, on relay water pump water outlet force pipe, pressure-reducing valve (the superpressure value is a fire fighting truck exit of pump pressure) is housed: and the bypass pipe magnetic valve is housed.Fire fighting truck has been if the feed pump colligator has supplied water, and the relay water pump turns round, and then magnetic valve should be in closed condition (computer regulated magnetic valve in pressure sensor that can be by installing on the air pressure tank, the switch board); (2) suction hose of relay water pump can directly draw water from underground conservation pool, and gate valve (maintenance is used), check valve are housed on the suction hose.Form standby each other on the water source with the water that comes of fire department pumper connection.Affixed power water pump and the automatic fire-fighting main pump same model that sprays are so water pump assembly is also standby mutually.Improved the security reliability of waterworks for firefighting greatly.When fire fighting truck also is not on the scene after breaking out of fire, anhydrous in the fire department pumper connection, then the relay water pump directly draws water from underground conservation pool.The superpressure phenomenon can not take place in this moment, can not make the bypass pipe magnetic valve be in full-gear by the pressure sensor on the air pressure tank (have and press), and the relay water pump is put out a fire with the rated condition input.
2 explanations: (1) when the fire extinguishing that put into operation of main fire pump, then fire department pumper connection, relay water pump system can be in stand-by state; (2) the relay water pump receive fire alarm or fire fighting truck supply water normal after, can start on time, move relay water pump (also can manually) automatically.Electrical equipment control has overcurrent, overheated, mistake hydraulic pressure, excessive low water level protection device and fire protection warning device.
Embodiment 3:
Present embodiment by fire department pumper connection 1, relay water pump 7, electro connecting pressure gauge 8, automatically spray main fire pump 13, air pressure tank 5, switch board 16, and respective one-way valve, gate valve constitute, switch board 20 is frequency conversion computer switch board, and on air pressure tank 5, set up teletransmission Pressure gauge 18 and electro connecting pressure gauge 19, and both detection signals are delivered to switch board 16.
The operation principle of present embodiment: after fire fighting truck had been on the scene during at fire, has connected siamese fire department connection, the heart so caused indoor fire-fighting pipe-line system superpressure.After the teletransmission Pressure gauge obtains signal, make water pump assembly fall running by computer (PLC) and frequency converter, and reduce water exit of pump pressure, make neither superpressure of hydraulic pressure, satisfy the fire-fighting requirement again.The utility model has reduced hydraulic resistance and energy loss, and water pump assembly belongs to soft start, has reduced starting current.Improved the security reliability of water relay system and mains supply comprehensively.
Special when fire-fighting and the shared underground conservation pool of life, can be with this frequency control relay water pump double as living water water pump, the living water water pump is frequent operation, frequency control can be energy-conservation greatly.Work as breaking out of fire, after the frequency conversion computer apparatus is accepted fire signal, improve frequency at once, promptly improve pump rotary speed, improve the fire extinguishing of hydraulic pressure input; But also the stand-by pump (promptly not selecting stand-by pump else) that can be designed to this frequency control relay water pump be the main fire pump of fire-fighting system is augmented press pump in the stabilized pressure pump of double as fire-fighting system and the roofing fire-fighting supplementary pressure system again simultaneously.Though RHVC needs bigger investment, several water pump assemblies and decompressor and large-scale air pressure tank have been saved in above-mentioned design.And outstanding advantages such as energy-conservation, soft start, system's safety and reliability are arranged.
