Description
Affiliated technical field
The utility model relates to fire pump starter, particularly programmable controller carry out programming Control to the fire water pump assembly fire pump sequence timing starter.
Background technology
At present, because the economic construction of China development is very swift and violent, buildings such as all kinds of high levels, field, shop can be found everywhere in each city.The generation of various unexpected stormses is following, wherein is the primary object of taking precautions against with the fire.In order to prevent the generation of unexpected fire, generally be equipped with special-purpose fire pump unit in all kinds of buildings.Stipulate according to Fire Service Act: necessary regularly, the test-run a machine operation regularly of fire pump unit.But, owing to many reasons, many equipment all for want of or basic unattended and test-run a machine operation regularly, will cause year in and year out that pump body is stuck, rust extremely.So the situation that fire-fighting equipment can not play one's part to the full when regular meeting appears at breaking out of fire, so that cause unnecessary heavy losses.What particularly the startup of common old equipment/operation conversion and control was used is leather cup vacuum type electrotimer, and its timing error is big, rubber is aging, damaged easily, safeguards inconvenience.Also there is similar problem in the electronic timing relay, demands urgently improving.
Summary of the invention
In order to solve the prior art deficiency, the utility model adopts programmable controller that the fire water pump assembly is carried out programming Control, can realize in water pump assembly is between standby period regularly, regularly try out, starts automatically during fire demand water.
Fire pump sequence timing starter, comprise programmable controller PLC, 1# fire pump field control cabinet contactor KM1,1# Fire Fighting Pump Control auxiliary reclay and timer, it is characterized in that the auxiliary contact of 1# fire pump field control cabinet contactor KM1 connect 0001 point of PLC, the auxiliary contact of 1# fire pump field control cabinet electrothermal relay FR1 connect 0005 point of PLC; 1# Fire Fighting Pump Control auxiliary reclay connects the PLC0500 point, and 1# fire pump alarm lamp connects the PLC0505 point, and 1# fire pump number of starts counter connects the PLC0510 point.Operation principle:
For the skyscraper of required four 15KW fire pumps, when not having the fire demand water demand, move after 30 seconds in 10 seconds of first starting mode of pump (star-like, frequency converter, soft start and stop), shut down await orders 120 hours (time from 0～indefinite duration is adjustable).If when not having the fire demand water demand during awaiting orders, then second starting mode of pump is 10 seconds, moves 30 seconds, shuts down and awaits orders 120 hours (time from 0～indefinite duration is adjustable), so again and again circulation.In switch board, there is the pump operation counter corresponding one by one, can notes down the running number of times of each water pump in real time with water pump.
In water pump test running process, can send signal in advance and notify the relevant personnel, when water pump hinders and when not turning round for some reason, can send sound and light alarm signal (gather feed back to PLC behind the signal and handle by contactor, electrothermal relay) automatically; When not shutting down after the water pump test running, (do not surpass 5～10 seconds time of setting); can send sound and light alarm signal (handling) automatically, cut off its power supply to reach the purpose of protection pipe network by auto-power-off device simultaneously by feeding back to PLC behind contactor, the electrothermal relay collection signal.
When the fire demand water demand was arranged, the pump group started pressurization immediately automatically and supplies water, and current detector on the pipeline and pressure sensor can detect water-flow signal and pressure signal automatically, make it give full play to its due effect.
When the condition of a fire occurring, if hydraulic pressure did not reach required pressure after first water pump put into operation, electro connecting pressure gauge low pressure detects the contact will be in off-state all the time, and second water pump puts into operation automatically; If still do not reach required pressure after second water pump input, it is still not closed that promptly Pressure gauge low pressure detects the contact, and then the 3rd water pump puts into operation automatically, so analogizes.During as hypertonia, water pump can be out of service by platform automatically.
The utility model is the improvement of fire pump starter, and it is reasonable in design, and is simple in structure, make easily, and use, easy to maintenance, cost is low; Reliability height, and can expanding according to different needs at an easy rate can not in time pressurize in the time of can stopping because of pump housing rust dead or fire demand water so effectively and produce serious consequence, is easy to penetration and promotion.
