Summary of the invention
This utility model purpose is to provide the electric control circuit of a kind of salt bag package machine air compressor machine, solves existing drawback, it is ensured that the work of each air compressor machine effective.
In order to realize object above, the technical solution adopted in the utility model is: a kind of electrical control circuit of air compressor, including several the air compressor machine circuit being connected with power lead-ining line successively, every air compressor machine circuit includes the air switch QF being connected with power supply, the A.C. contactor KM being connected between air switch QF and motor M, it is connected between A.C. contactor KM with motor M and has insurance resistance RF, between every air compressor machine circuit, time relay KT is set, every air compressor machine circuit arranges pressure switch K, pressure switch K of preamble air compressor machine circuit is sequentially connected with the time relay KT of postorder air compressor machine circuit.
Of the present utility model have the technical effect that 1, be initially powered, run after starting by platform after several air compressor machine time delay several seconds successively, time is set by the time relay, so, instant starting currents is little, and little on main line impact, voltage pulsation is little, and be again started up, run after starting by platform after the air compressor machine time delay several seconds the most successively；2, one to two handpiece of air compressor temperature of preamble reduces, and carbon distribution is few, head life；3, the air accumulator of air compressor machine pressure all the time is sufficient, salt bag automatic packaging unit Pneumatic component normal operation；4, outside every compressor operation is controlled by respective pressure switch, postorder air compressor machine is controlled by preamble pressure switch of air compressor simultaneously, preamble increase successively to the pressure of postorder pressure switch of air compressor.
Accompanying drawing explanation
Fig. 1 is electric control circuit figure of the present utility model；
Fig. 2 is the structure diagram of the time relay in this utility model.
Detailed description of the invention
Here explaining lower preamble air compressor machine, the concept of postorder air compressor machine, several the air compressor machines being sequentially arranged are sequential starts, and when several air compressor machines normally work, the definition first started is preamble air compressor machine, and the rear definition started is postorder air compressor machine.With reference to Fig. 1, air compressor machine is exactly the startup successively of dextrosinistral M1, M2, M3, M4.
A kind of electrical control circuit of air compressor, including several the air compressor machine circuit being connected with power lead-ining line successively, every air compressor machine circuit includes the air switch QF being connected with power supply, the A.C. contactor KM being connected between air switch QF and motor M, it is connected between A.C. contactor KM with motor M and has insurance resistance RF, between every air compressor machine circuit, time relay KT is set, every air compressor machine circuit arranges pressure switch K, and pressure switch K of preamble air compressor machine circuit is sequentially connected with the time relay KT of postorder air compressor machine circuit.
Referring to the drawings, every air compressor machine road connects with on three-phase alternating current, and air switch QF1, QF2, QF3, QF4 can also play the effect of overload protection automatic tripping power-off while playing the effect connecting and closing section in the line；A.C. contactor KM1, KM2, KM3, KM4 auxiliary contact performs control instruction；Insurance resistance RF1, RF2, RF3, RF4 have the effect of resistor and fuse concurrently, and when temperature exceedes certain altitude (such as 500 degree), resistive layer rapid deterioration fuses, and circuitry cuts, plays the effect of protection circuit；Time delay a period of time contact output after the time relay KT1, KT2, KT3, KT4 energising added, (time is by time relay KT sets itself) is run after starting by platform after being so initially powered several the air compressor machines time delay several seconds successively, instant starting currents is little, little on main line impact, voltage pulsation is little, when being again started up, run after starting by platform after the air compressor machine time delay several seconds the most successively；The effect of pressure switch K is, outside every compressor operation is controlled by respective pressure switch K, postorder air compressor machine is controlled by preamble pressure switch of air compressor K simultaneously, increased successively to the pressure of postorder pressure switch of air compressor K by preamble, it is preferred that pressure increases 0.01MP successively, in conjunction with Fig. 1, K1 relatively K2 pressure increases 0.01MP, K2 relatively K3 and increases 0.01MP, by that analogy.The most each air compressor machine works the most in order, and preamble handpiece of air compressor compares that existing temperature reduces, carbon distribution is few, head life；The air accumulator of air compressor machine pressure all the time is sufficient, packer Pneumatic component normal operation.
Preferably, every air compressor machine air switch QF1, QF2, QF3, QF4 are provided with overcurrent relay coil.This is equivalent to add overcurrent relay, and when overload and short trouble occurs in electricity system, this relay can excise faulty component by predetermined time limit action message or send signal, it is ensured that the safety of electricity system.
With reference to Fig. 1, further, this circuit includes four the air compressor machine circuit being connected successively with power lead-ining line, arranges three time relay KT between four air compressor machine circuit, and pressure switch K of preamble air compressor machine circuit is sequentially connected with the time relay KT of postorder air compressor machine circuit.K1-K4 is referred to as air engine pressure switch K, it is preferred that when K is adjusted to 0.45-0.8MP, and when air pressure reaches 0.8MP, K disconnects, and air compressor machine quits work.When air pressure near≤0.45MP time, K close, compressor operation, as pressure 0.45MP, air compressor machine does not starts.
In conjunction with Fig. 1,2, time relay KT equivalent circuit theory illustrates: 220V power supply inputs through 2,7 feet, DC source is obtained after all wave rectification voltage stabilizing, the delay circuit of the RC composition within the supply of this power supply, R is adjustable potentiometer, the regulation big I of R changes delay time length, and JK is relay normally open contact, and relay coil one end is connected on the positive pole of power supply, the other end is connected on the delay circuit formed by RC and is controlled.When relay coil obtains after electric JK closes, and 8,6 conductings, compressor operation, when N disconnects, 8,6 disconnect, and air compressor machine is out of service.N is controlled by pressure switch of air compressor K.
It is further preferred that described time relay KT is the air damp type time relay.Electronical time relay is stirred by voltage to be affected with variation of ambient temperature, and anti-interference is poor, is not suitable for the workshop condition of salt bag packaging production line；Motor time relay structure is complicated, is not suitable for frequent operation, and delay time error is affected bigger by supply frequency.Owing to air damp type time relay reference time delay is relatively big (0.4 ~ 180s), and not affected by voltage and frequency fluctuation and can make energising and two kinds of delayed version simple in construction of power-off, the life-span is long, it is advantageous to this time relay.
