Dredge pump control wiring
Technical field
The present invention relates to electrical control equipment manufacturing technology field, especially a kind of dredge pump control wiring switched mutually for two water pumps of sewage.
Background technique
Along with the development of urban construction, the community that people live, hospital and school get more and more, meanwhile, underground parking also gets more and more, the thing followed is more and more higher to the requirement of the dredge pump of underground parking, the dredge pump unit great majority of current underground parking are all that a set of dredge pump unit is by an Electric Machine Control, if this cover dredge pump unit breaks down, once encounter heavy rain or rainstorm weather, sewage can not be discharged in time, if the automobile be parked in parking lot can not output parking lot in time, automobile will be made not had by water logging, thus cause any property loss.
Summary of the invention
The object of this invention is to provide a kind of dredge pump control wiring, it can solve once a set of water pump breaks down, and sewage can not be discharged in time, if the automobile be parked in parking lot can not output parking lot in time, automobile will be made not had by water logging, thus the problem caused any property loss.
In order to solve the problem, the technical solution used in the present invention is: this dredge pump control wiring, comprises No. 1 pump contactor, No. 1 pump thermorelay, No. 2 pump contactors and No. 2 pump thermorelays; Also comprise No. 1 pump startup time relay, No. 2 pump startup time relays and termination of pumping relay; Throw over switch, the described No. 1 pump startup time relay and water level controller series connection formation No. 1 pump startup circuit; Described throw over switch, No. 2 pump startup time relays and water level controller series connection formation No. 2 pump startup circuit; Described termination of pumping relay and water level controller series connection form termination of pumping circuit;
Described throw over switch, termination of pumping relay, No. 1 pump thermorelay and No. 1 pump contactor series connection formation No. 1 pump manual circuit; Described throw over switch, No. 1 pump startup time relay, termination of pumping relay, No. 1 pump thermorelay and No. 1 pump contactor series connection formation No. 1 pump automatic circuit; Described No. 1 pump contactor is in parallel with the described No. 1 pump startup time relay forms holding circuit; Described throw over switch, No. 2 pump startup time relays, No. 2 pump contactors, termination of pumping relay, No. 1 pump thermorelay and No. 1 pump contactor series connection formation No. 1 pump standby self-closing circuit;
Described throw over switch, termination of pumping relay, No. 2 pump thermorelays and No. 2 pump contactor series connection formation No. 2 pump manual circuits; Described throw over switch, No. 2 pump startup time relays, termination of pumping relay, No. 2 pump thermorelays and No. 2 pump contactor series connection formation No. 2 pump automatic circuits; Described No. 2 pump contactors are in parallel with the described No. 2 pump startup time relays forms holding circuit; Described throw over switch, No. 1 pump startup time relay, No. 1 pump contactor, termination of pumping relay, No. 2 pump thermorelays and No. 2 pump contactor series connection formation No. 2 pump standby self-closing circuit.
Owing to have employed technique scheme, the present invention compared with prior art, the beneficial effect had is: adopt two cover dredge pump units, a set of water pump assembly work, another set of water pump assembly is for subsequent use, and when the water pump assembly of work breaks down, reserve pump unit is devoted oneself to work automatically, thus avoid because of fault of water pump, cause sewage to discharge in time and the problem of the property loss caused.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described: the dredge pump control wiring shown in Fig. 1, comprises No. 1 pump contactor 1Q, No. 1 pump thermorelay 1RJ, No. 2 pump contactor 2Q and No. 2 pump thermorelay 2RJ; Also comprise No. 1 pump startup time relay 1SJ, No. 2 pump startup time relay 2SJ and termination of pumping relay 1ZJ; Throw over switch BK, No. 1 pump startup time relay 1SJ and water level controller GSW series connection formation No. 1 pump startup circuit; Throw over switch BK, No. 2 pump startup time relay 2SJ and water level controller GSW series connection formation No. 2 pump startup circuit; Termination of pumping relay 1ZJ and water level controller GSW connects and forms termination of pumping circuit;
Throw over switch BK, termination of pumping relay 1ZJ, No. 1 pump thermorelay 1RJ and No. 1 pump contactor 1Q series connection formation No. 1 pump manual circuit; Throw over switch BK, No. 1 pump startup time relay 1SJ, termination of pumping relay 1ZJ, No. 1 pump thermorelay 1RJ and No. 1 pump contactor 1Q series connection formation No. 1 pump automatic circuit; No. 1 pump contactor 1Q is in parallel with No. 1 pump startup time relay 1SJ forms holding circuit; Throw over switch BK, No. 2 pump startup time relay 2SJ, No. 2 pump contactor 2Q, termination of pumping relay 1ZJ, No. 1 pump thermorelay 1RJ and No. 1 pump contactor 1Q series connection formation No. 1 pump standby self-closing circuit;
Throw over switch BK, termination of pumping relay 1ZJ, No. 2 pump thermorelay 2RJ and No. 2 pump contactor 2Q series connection formation No. 2 pump manual circuits; Throw over switch BK, No. 2 pump startup time relay 2SJ, termination of pumping relay 1ZJ, No. 2 pump thermorelay 2RJ and No. 2 pump contactor 2Q series connection formation No. 2 pump automatic circuits; No. 2 pump contactor 2Q are in parallel with No. 2 pump startup time relay 2SJ forms holding circuit; Throw over switch BK, No. 1 pump startup time relay 1SJ, No. 1 pump contactor 1Q, termination of pumping relay 1ZJ, No. 2 pump thermorelay 2RJ and No. 2 pump contactor 2Q series connection formation No. 2 pump standby self-closing circuit.
During work, if No. 1 pump is as working pump, No. 2 pumps are stand by pump, throw over switch BK are got to No. 1 pump work/No. 2 pump gear for subsequent use, if wastewater level reaches the height of setting, water level controller GSW connects and makes No. 1 pump startup time relay 1SJ adhesive action, throw over switch BK, No. 1 pump startup time relay 1SJ, termination of pumping relay 1ZJ, No. 1 pump automatic circuit energized action that No. 1 pump thermorelay 1RJ and No. 1 pump contactor 1Q series connection is formed, No. 1 outside draining of pump startup; If No. 1 pump is not activated within the time of setting, then illustrate that No. 1 pump there occurs fault, now, throw over switch BK, No. 1 pump startup time relay 1SJ, No. 1 pump contactor 1Q, termination of pumping relay 1ZJ, No. 2 pump standby self-closing circuit of No. 2 pump thermorelay 2RJ and No. 2 pump contactor 2Q series connection formation must electrically connect, No. 2 pump contactor 2Q adhesive actions, No. 2 outside drainings of pump startup.If wastewater level has dropped to the low water level of setting, termination of pumping relay 1ZJ and water level controller GSW series connection has formed termination of pumping circuit and must electrically connect, and termination of pumping relay 1ZJ obtains electric adhesive action, disconnects working circuit, and water pump is shut down;
If No. 2 pumps are as working pump, No. 1 pump is stand by pump, throw over switch BK is got to No. 2 pump work/No. 1 pump gears for subsequent use, if wastewater level reaches the height of setting, water level controller GSW connects and makes No. 2 pump startup time relay 2SJ adhesive actions, throw over switch BK, No. 2 pump startup time relay 2SJ, termination of pumping relay 1ZJ, No. 2 pump automatic circuit energized actions that No. 2 pump thermorelay 2RJ and No. 2 pump contactor 2Q series connection are formed, No. 2 outside drainings of pump startup; If No. 2 pumps are not activated within the time of setting, then illustrate that No. 2 pumps there occurs fault, now, throw over switch BK, No. 2 pump startup time relay 2SJ, No. 2 pump contactor 2Q, termination of pumping relay 1ZJ, No. 1 pump standby self-closing circuit of No. 1 pump thermorelay 1RJ and No. 1 pump contactor 1Q series connection formation must electrically connect, No. 1 pump contactor 1Q adhesive action, No. 1 outside draining of pump startup.If wastewater level has dropped to the low water level of setting, termination of pumping relay 1ZJ and water level controller GSW series connection has formed termination of pumping circuit and must electrically connect, and termination of pumping relay 1ZJ obtains electric adhesive action, disconnects working circuit, and water pump is shut down.
