Described automatic control circuit is by relay J 1, J2, triode Q1, Q3, Q4, Q5, and controllable silicon Q2, resistance R 1, R2, R3, R4, R5, R6 connection in series-parallel constitute.Wherein J1 is the switching value pilot relay, and J2 is the SCR control relay.The normally opened contact of described switching value pilot relay J1 by the switching value outlet terminal 1., 2. be connected with main contactor coil ZC and secondary insurance RD2 series connection and with any two of three-phase supply.The normally opened contact of SCR control relay J 2 is connected to the mid point of controllable silicon Q2 anode and resistance in series R1, R2.Described triode Q1 is the control triode of switching value pilot relay J1, and its collector is connected with switching value pilot relay J1, and emitter is connected to power cathode, and base stage then is connected with biasing resistor R1, R2.The control triode that described triode Q3 is a SCR control relay J 2, its emitter is connected to power cathode, and collector is connected with SCR control relay J 2, and base stage is connected in the emitter of triode Q4.The base drive triode that described triode Q4 is triode Q3, its collector is connected with resistance R 3, and base stage is connected with current-limiting resistance R5.The base stage power supply control controllable silicon that described controllable silicon Q2 is triode Q1, anode is connected to normally opened contact one end of SCR control relay J 2, and negative electrode connects power cathode, and the control utmost point is connected to the emitter of triode Q5.Described triode Q5 is the driving tube of controllable silicon Q2, and its emitter is connected with the control utmost point of controllable silicon Q2, and collector is connected with resistance R 4, and base stage is connected with current-limiting resistance R6.
A described sump probe terminals end 5. links to each other with the positive pole of low-voltage dc power supply, and a sump probe terminals end 6. is connected with resistance R 5, and a sump probe terminals end 7. is connected with resistance R 6.Sump probe terminals 5., 6., the other end 7. then connects respectively at sump probe A, B, C.
Principle of work of the present invention is as follows:
During work, the master switch DK that closes, automatic water-feeding controller at first judge by detecting water bunker level whether water pump works.If water level is when the sump probe A is following, water pump begins to start goes up water, and water level begins to rise, and when water level rose to the sump probe A, automatic water-feeding controller control water pump stopped to go up water.Along with the prolongation of water time, water level begins to descend, when decline of water table is following to the sump probe B, automatic water-feeding controller control water pump begins to start upward water again, when treating that water level rises to the sump probe A, automatic water-feeding controller is controlled water pump again and is stopped to go up water, thereby obtains the purpose of automatic loading water.The physical circuit principle of work is as follows.
After the power on circuitry, when water level when the sump probe B is following, three contacts of sump probe A, B, C all are open-circuit condition each other, resistance value is infinitely great, triode Q4 and triode Q5 can not get the base stage supply voltage, all are operated in cut-off state.The base stage of triode Q3 can not get the power supply of triode Q4, also is operated in cut-off state.To not influence of triode Q1, triode Q1 works in the saturation conduction state in off-state this moment for the contact of SCR control relay J 2, the switching value pilot relay J1 closing of contact, and main contactor coil ZC gets electric also closed, and water pump begins to switch on and goes up water.
When water level rises to the sump probe B, because the electric action of water, between sump probe B and sump probe C, form a resistance value, the direct supply positive voltage just provides a base stage supply voltage for triode Q4 by the resistance and the resistance R 5 of water between sump probe B, C, make triode Q4 conducting, thereby drive triode Q3 saturation conduction, SCR control relay J 2 contacts begin adhesive.Because this moment, triode Q5 still worked in cut-off state, can not trigger controllable silicon Q2 conducting, controllable silicon Q2 works in cut-off state, and to still not influence of triode Q1, triode Q1 also works in the saturation conduction state, water on the water pump maintenance.
When water level rises to the sump probe A, between sump probe A, C, also formed a resistance value, the power supply positive voltage provides a base stage supply voltage for triode Q5 by the resistance and the resistance R 6 of water between sump probe A, C, make triode Q5 conducting, thereby trigger controllable silicon Q2 conducting, after the controllable silicon Q2 conducting short circuit base stage supply voltage of triode Q1, triode Q1 becomes cut-off state by conducting state, switching value pilot relay J1 dead electricity contact disconnects, thereby the control Pump Failure stops to go up water.
When decline of water table is following to the sump probe A, disconnected the resistance value between sump probe A, C, triode Q5 is become by conducting and ends, but because silicon controlled characteristic, after conducting, lose trigger voltage and still can continue conducting, Gu the triode Q5 of this moment is to not influence of controllable silicon Q2, controllable silicon Q2 is also in conducting state, and water pump still is in off-position.
When water level continues to drop to the sump probe B when following, disconnected the resistance value between sump probe B, the C, triode Q4 can not get the base stage supply voltage admittedly, become cut-off state by conducting state, thereby triode Q3 ends also, SCR control relay J 2 dead electricity contacts disconnect, triode Q1 base stage restores electricity at once, become conducting state by cut-off state, switching value pilot relay J1 gets the electric contact adhesive, thereby water is gone up in the energising again of control water pump.
