Description
Technical field:
The utility model relates to a kind of control circuit of pollution discharge pump, particularly a kind of automatic pollution discharge pump control circuit.
Background technique:
The pollution discharge pump system of automatic control, environment is more abominable under general situation, and the automatic pollution discharge pump is drained ball float when water and is fallen, motor stall when running into lower position switch when work.But when ball float blocked by foreign matter or lower position switch when malfunctioning motor can change down always because that the few water of the pump housing is easy to generate heat is stuck, cause burn-down of electric motor.With reference to Fig. 1, the existing pollution discharge pump system, control circuit of control automatically comprise the motor major loop, be parallel with between power supply control A end and the N end down liquid level control branch road, on liquid level control branch road, pump control branch road and two-way trouble light branch road, fus 2 of serial connection when the input of power supply control A end, be serially connected with motor 16 in the motor major loop, hold relay switch 9-1, A.C. contactor normally opened contact 8-2 and air-break switch 1, following liquid level control branch road is the following liquid-level switch 3 and the auxiliary reclay coil 4 of serial connection; Last liquid level control branch road is last liquid-level switch 6, auxiliary reclay normally-closed contact 4-1 and the auxiliary reclay coil 5 of serial connection, the A.C. contactor normally opened contact 8-1 in parallel at last liquid-level switch 6 two ends; Pump control branch road is button 6, button 7, the A.C. contactor 8 of serial connection and holds relay 9, is parallel with auxiliary reclay normally opened contact 5-1 at button 7 two ends; Two-way trouble light branch road is respectively A.C. contactor normally-closed contact 8-3, the trouble light 10 of serial connection; And serial connection A.C. contactor normally opened contact 8-4, trouble light 11.Switch on when following liquid-level switch 3 arrives low water level, closure when last liquid-level switch 6 arrives high water level.Auxiliary reclay coil 5 gets by the normally closed of auxiliary reclay normally-closed contact 4-1, the normal battle of the A.C. contactor 8 of control pump by auxiliary reclay normally opened contact 5-1 (at this moment auxiliary reclay coil 5) must, the major loop of motor begins rotation by A.C. contactor normally opened contact 8-2, and the pump housing draws water.When water level is extracted into down liquid-level switch 3, following liquid-level switch 3 closures get auxiliary reclay coil 4, auxiliary reclay normally-closed contact 4-1 disconnects, auxiliary reclay coil 5 dead electricity auxiliary reclay normally opened contact 5-1 are disconnected, cause A.C. contactor 8 dead electricity A.C. contactor normally opened contact 8-2 to disconnect major loop motor is stopped.When water level was high-order again, pollution discharge pump went round and began again like this according to above-mentioned logic operation.If following liquid-level switch 3 malfunctioning switches or blocked by foreign matter at this moment, motor can change down always like this, pump housing operation under the situation of lack of water stuck burn-down of electric motor that causes at last that can generate heat.
The model utility content:
It can guarantee the automatic pollution discharge pump control circuit of the pump housing and motor safety when the purpose of this utility model provided a kind of breaking down.What solve mainly that the pollution discharge pump system of existing control automatically exists is blocked by foreign matter or lower position switch when malfunctioning when ball float, and the pump housing lacks water and is easy to generate heat stuck, causes the technical problem of burn-down of electric motor.
Technical solutions of the utility model are: a kind of automatic pollution discharge pump control circuit, comprise the motor major loop, be parallel with between power supply control A end and the N end down liquid level control branch road, on liquid level control branch road, pump control branch road and two-way trouble light branch road, it is characterized in that: time relay control branch road in parallel again between power supply control A end and N end.Described time relay control branch road is divided into two-way, one tunnel auxiliary reclay normally opened contact, auxiliary reclay normally-closed contact and time relay coil for serial connection, another road is button, time relay normally opened contact and the auxiliary reclay coil of serial connection, the auxiliary reclay normally opened contact in parallel at time relay normally opened contact two ends, the trouble light in parallel at auxiliary reclay coil two ends.A.C. contactor normally opened contact serial connection time relay normally-closed contact at last liquid level control branch road.
The beneficial effects of the utility model are, outside guaranteeing the original line function of automatic pollution discharge pump, increase the merely hit tutorial light of a relay, a reset button, a demonstration fault of a time relay.The time relay that on circuit, increases, pick up counting when pump work, its time is set at 〉=once drains the time of water, has both made the situation that above-mentioned fault occurs, the motor of pump can stop in the time of setting automatically, and does not influence the work of high water level next time.Show the trouble signal that have memory function on the control panel this moment, and this trouble signal just can disappear after getting rid of, reset in fault, guarantees the safety of the pump housing and motor.
