Abstract
The invention discloses a sewage pump control device, and relates to the technical field of electrical control. The sewage pump control device comprises a control cabinet, wherein a contactor and a thermal relay are mounted in the control cabinet; a change-over switch is mounted on a cabinet door; a relay for open-phase protection is further mounted in the control cabinet; the change-over switch, the relay, the thermal relay and the contactor are connected in series to from a manual operating circuit; the change-over switch, a start relay, the relay, the thermal relay and the contactor are connected in series to from an automatic circuit; a float switch and the start relay are connected in series to from a starting signal circuit; one end of each of the manual operating circuit, the automatic circuit and the relay is connected with a first phase of a three-phase source, the other ends of the manual operating circuit and the automatic circuit are connected with a second phase of the three-phase source, and the other end of the relay is connected with a third phase of the three-phase source. The sewage pump control device can solve the problem of economic loss caused by serious results such as motor burning, pump body damage and the like due to open phase of the motor.
Description
Technical field
The present invention relates to electrical control equipment manufacturing technology field, especially a kind of control wiring for pollution discharge pump.
Background technique
Development along with urban construction, community, hospital and school that people live are more and more, and meanwhile, underground parking is also more and more, the thing followed is more and more higher to the requirement of the dredge pump of underground parking, when arrive rainy season, pollution discharge pump is in unserviced situation, and what allow people worries most is line fault, such as motor phase failure etc., can cause motor damage, damage the serious consequences such as the pump housing, thereby cause economic loss.
Summary of the invention
The object of this invention is to provide a kind of pollution discharge pump control gear, it can solve motor phase failure, causes motor damage, damages the serious consequences such as the pump housing, thereby causes the problem of economic loss.
In order to address the above problem, the technical solution used in the present invention is: this pollution discharge pump control gear, comprise control box, and contactor and thermorelay are installed in this control box; On its chamber door, throw over switch is installed; Relay for open-phase protection is also installed in described control box; Described throw over switch, relay, thermorelay and contactor series connection form manual circuit; Described throw over switch, starting relay, relay, thermorelay and contactor series connection form automatic circuit; Switch is connected with described starting relay and is formed actuating signal circuit; Described manual circuit, one end of automatic circuit and described relay is connected with one of three phase mains respectively, another of the other end of described manual circuit and automatic circuit and three phase mains is connected, and the other end of described relay is connected with the remainder of three phase mains one.
Owing to having adopted technique scheme; the present invention compared with prior art; the beneficial effect having is: owing to being provided with phase failure relay; when there is the situation of disconnected phase; relay disconnecting circuit, can not start motor, thereby has protected motor and the pump housing; motor and the pump housing can not burnt mutually because of disconnected, avoided economic loss.
Accompanying drawing explanation
Fig. 1 is electrical principle schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Pollution discharge pump control gear shown in Fig. 1 is provided with contactor Q in control box, thermorelay RJ, starting relay ZJ1 and for the relay ZJ of open-phase protection; Throw over switch BK is installed on the chamber door of control box; Throw over switch BK, relay ZJ, thermorelay RJ and contactor Q series connection form manual circuit; Throw over switch BK, starting relay ZJ1, relay ZJ, thermorelay RJ and contactor Q series connection form automatic circuit; Switch GSW connects with starting relay ZJ1 and forms actuating signal circuit; Manual circuit, one end of automatic circuit and relay ZJ is connected with the A of three phase mains respectively, and manual circuit and the other end of automatic circuit and the C of three phase mains are connected, and the other end of relay ZJ is connected with the B of three phase mains.During work, throw over switch BK is got to automatic catch, when sewage is raised to setting high-order, switch GSW connect with starting relay ZJ1 the actuating signal circuit that forms obtain electric, starting relay ZJ1 adhesive action, throw over switch BK, starting relay ZJ1, relay ZJ, thermorelay RJ and contactor Q series connection form automatic circuit and connect, contactor Q obtains electric adhesive action, and motor start-up also drags the outside draining of water pump; If throw over switch BK is got to manual gear, throw over switch BK, relay ZJ, thermorelay RJ and contactor Q series connection form manual circuit and connect, and contactor Q obtains electric adhesive action, and motor start-up also drags the outside draining of water pump; If there is phase shortage, such as B breaks mutually, relay ZJ can adhesive, no matter be that manual circuit or automatic circuit are all opened circuit, cannot connect, and this just makes motor can not start, thereby protection motor can not be burned because of phase shortage.
