Description of drawings

Fig. 1 is circuit theory diagrams of the present utility model;

Fig. 2 is the circuit diagram of intrinsically safe circuit SZKJ among Fig. 1.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to Fig. 1, Fig. 2, the working principle of the utility model water pump automatic vacuum magnetic force control is:

" manual " selector switch K1 of water pump automatic vacuum magnetic force control is in the time of 1, and the start and stop of controller realize control drainage procedure automatically by SZKJ.When SZKJ plug-in unit or subsidiary component break down, or when need not to control automatically, K1 can be allocated to 2, utilizes the start-stop of button QA, TA control of pump on the spot.

The 36V power supply of KB1 output is through transformer KB2 isolation and be depressurized to 12v, rectifier bridge ZL rectification, and capacitor C 1, C2 filtering, the integrated voltage stabilizing of W is the direct current of 12v, uses for entire circuit.

After ZJ discharged, time relay time-delay 5S discharged, and SJ1 timing closing is to guarantee the not misoperation of SDB protector.

Be provided with H, L, three water level detecting electrodes of M in the sump, place the default different heights of water respectively, H is a upper limit water level, and L is the lower limit water level, and M is a common port.

When the water level rising, when being higher than the H point, probe H, L are low level, the circuit upset, and IC1 exports high level, triode Q conducting, relay 1J adhesive, the luminous indication of D1.

During relay 1J adhesive, contact 1J1 disconnects, the time-base integrated circuit IC2 beginning of delaying time; 1J2 connects bypass solenoid valve F1 and exhaust solenoid valve F2 simultaneously, and beginning is poured water in the pump housing and exhausting air.

Time base circuit IC2 as required can be adjustable continuously by potentiometer RP between 30～180s.When the time that arrives setting, when suction line is full of water, the IC2 output low level, relay 2J adhesive, its break contact 2J1 disconnects, and bypass valve F1 and outlet valve F2 do not have electricity and close, and stop the exhaust of pouring water.Simultaneously, normal opened contact 2J2 connects the adhesive loop of auxiliary reclay, and water pump must be established the beginning by cable and draw water, luminous indication simultaneously, and contact 2J3 closure is to scheduling night shift room feedback pump working state.

When drawdown is between H, L, still keep logic state constant, water pump works on.

When water level continuation decline, when being lower than the L point, probe H, L all break away from water and become high level, and circuit overturns again, output low level, and relay 1J discharges, 1J2 disconnection solenoid valve loop; The 1J1 closure forces trigger end to become low level, circuit upset output high level, make 2J also discharge, contact 2J1 closure, for next pump priming exhaust is prepared, 2J2 disconnects auxiliary reclay end ZJ adhesive loop, intermediate relay ZJ discharges, make vacuum contactor ZKJ also not have electricity and discharge, water pump shuts down, and drainage works finishes.

When rising of groundwater level arrived between H, the L, logical circuit was constant, still maintain the original state, and not adhesive of 1J, water pump is not worked.

Go up when the water level continuation, when being higher than the H point, circuit overturns again, output high level, relay 1J adhesive again.Water pump begins the venting of pouring water again, draws water then.So repeat above-mentioned control procedure, automatic cycle work.

K1 is automatic, manual mode selector switch, is automatic control mode when placing 1, is manually nearly prosecutor formula when placing 2.

Functional select switch K2 is a working mode selection, and when placing 1, pump working is in the few termination of pumping mode of water full gate pump water; When placing 2, pump working is in the full termination of pumping mode of the few turn on pump water of water.

When if this controller is applied to the control of submersible pump, can exempt to connect bypass valve and outlet valve, time-delay is transferred to minimum getting final product.

When controller have overload, short circuit, the phase failure, electric leakage, etc. during fault, 3,4 lines of SDB disconnect, and cut off the power supply of control loop, controller can not be worked and send indicating fault by the LED window.

When water pump fault or the empty pump water that do not turn round, make when temperature rise is too high to reach 30 ℃, the temperature relay T that is installed on the pump housing can be closed immediately, force the base stage of triode Q to become low level and end, 1J, 2J are discharged, and 2J2 disconnects the starter control loop, and water pump shuts down.When pump body temperature cooling recovers just often, temperature relay T disconnects again, and logical circuit is resetted, and Q is conducting again, and 1J is adhesive again, the 2J adhesive of also delaying time, and water pump begins the auto-irrigation exhaust again, and turn on pump then is till last water is normal.If occur termination of pumping continually, turn on pump in the short time, the phenomenon that 2J3 is frequent closed, disconnect represents that then water pump do not take out water, and the pump housing or suction line have fault.The corresponding light emitting diode D2 indication of frequently glimmering in the LED indicator window simultaneously, contact 2J3 is break-make repeatedly, and the operator on duty sends failure warning to scheduling, checks processing with prompting.
