Description

Automatic timing lubricates control gear
Technical field
The utility model relates to the lubricated control gear of a kind of electronic lubricant pump automatic timing.
Background technique
Electronic lubricant pump is the supply arrangement of machinery centralized lubrication, is widely used on the big-and-middle-sized machinery.Electronic lubricant pump individual electric element comprises switch, contactor, the time relay, auxiliary reclay and pressure gauge with electric contact etc., oiling when controlling motor stator by the closed and disconnected of electric elements.Because the individual electric element is more, the electric wiring complexity, contacts such as the time relay, auxiliary reclay are too much, occur faults such as bad connection easily, and the equipment that influences normally moves, and the maintenance difficulty is big.
Summary of the invention
The utility model purpose overcomes above-mentioned the deficiencies in the prior art exactly, provides that a kind of individual electric element is few, fault is few, is convenient to the lubricated control gear of automatic timing of electrical repair.
The utility model comprises circuit major loop and control loop; 380 volts of voltages of circuit major loop input AC enter circuit breaker ZK1 then, by contactor JC disjunction, and control thermorelay RJ break-make, and then control lubrication motor M operation; Control loop is a core with programmable controller PLC, power supply is introduced L, the N interface of PLC by circuit breaker ZK2; Com interface is a PLC input signal side common port, the moving oiling stop button SB1 of X1 catcher, and the moving oiling button SB2 of X3 catcher, the moving ann reset button SB3 that removes of X5 catcher, X7 meets pressure gauge with electric contact DJ, and X10 connects motor heat relay R J normally-closed contact; The output supply voltage of PLC is for exchanging 220 volts; Receive on the circuit breaker ZK3 after COM1, COM2 and the COM3 parallel connection, the Y1 port of PLC outputs to auxiliary reclay KA1, and the normally opened contact of KA1 is received on the contactor JC; The Y2 port outputs to auxiliary reclay KA2, and the normally opened contact of KA2 is received on the solenoid valve DT; Y3, Y4 port meet oil pump run indicator D1, D2; The Y5 port connects the malfunction alarm tutorial light.
The utility model is applicable to grease centralized lubrication equipment, particularly electronic lubricant pump.
The utility model adopts programmable controller to replace the individual electric element, complicated electric interlock and timing controlled, by programming input programmable logic controller inside, the outside only stays simple input/output signal, and the tutorial light of programmable controller, the situation of reflected signal input output intuitively is convenient to electrical repair personnel failure judgement.
Few, the reliable in action of the utility model individual electric element, fault is few, and programmable controller signal input output indication is directly perceived, is convenient to observe maintenance.Programmable controller can accurately be controlled the oiling time, and is complete to oil pump leakage of oil, overload protection.The external electrical control wiring adopts in parallel the binding, and having any to break down does not influence overall operation.Respond well through trying out, the equipment that guaranteed is normally lubricated.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Embodiment
Adopt the transparent HH62P auxiliary reclay of moulding shell sealing electrical contact to replace the big packing less ZJ7--44 auxiliary reclay of volume, avoid the erosion of dust and greasy dirt, reduce fault.Electronic lubricant pump model is ZRZ-1300.Can adopt automatic, manually dual mode oiling.
During automatic oiling, power turn-on switch ZK1~ZK3, power supply indicator D4 is bright, and programmable controller PLC must establish the beginning timing by cable.After arriving Preset Time (general 1 hour at interval), auxiliary reclay KA1, KA2 adhesive, KA1, KA2 normally opened contact closure, A.C. contactor JC and solenoid valve DT line Bao Dedian adhesive, lubrication motor M starts working, and opens pipe valve simultaneously to the equipment oiling.When the pipeline oil pressure reaches setting value, pressure gauge with electric contact DJ normally opened contact closure, auxiliary reclay KA1, KA2 dead electricity, contactor JC and solenoid valve DT dead electricity, lubrication motor M stops pump oil, and PLC picks up counting again, reaches Preset Time when the Cumulative time, begin next oiling again, and circulation is gone down always.
Manually during oiling, power turn-on switch ZK1~ZK3, power supply indicator D4 is bright, and programmable controller PLC picks up counting.Press manual oiling button SB2, auxiliary reclay KA1, KA2 adhesive, KA1, KA2 normally opened contact closure, A.C. contactor JC and solenoid valve DT line Bao Dedian adhesive, lubrication motor M starts working, and opens pipe valve simultaneously to the equipment oiling.When the pipeline oil pressure reaches setting value, pressure gauge with electric contact DJ normally opened contact closure, auxiliary reclay KA1, KA2 dead electricity, contactor JC and solenoid valve DT dead electricity, lubrication motor M stops pump oil.
When oiling pipeline breakage leakage of oil, pressure gauge with electric contact DJ normally opened contact can not be closed in set time, and programmable controller PLC makes auxiliary reclay KA1, KA2 dead electricity, and lubrication motor M stops pump oil, and alarm indicator lamp D2 lights, and needs maintenance and inspection this moment.When lubricant pump obstruction or motor overload, thermorelay RJ normally-closed contact disconnects, and programmable controller PLC makes auxiliary reclay KA1, KA2 dead electricity, and lubrication motor M stops pump oil, and alarm indicator lamp D2 lights, and needs maintenance.After repairing fault, can recover oiling work by reset button SB3.
