Detailed description of the invention
As it is shown in figure 1, the automatic control type vacuum system of energy-conserving and environment-protective of the present utility model mainly includes vacuum pump 4, surge tank 5, normal-closed electromagnetic valve 2, pressure vacuum gauge 3 and control unit 1.Wherein, vacuum pump connects with surge tank, and normal-closed electromagnetic valve and pressure vacuum gauge are arranged on surge tank, is simultaneously used for driving the motor of vacuum pump, normal-closed electromagnetic valve and pressure vacuum gauge to electrically connect with control unit.
Forward Fig. 2 to, describe control unit and the structure of control circuit.As shown in the drawing, control unit specifically includes converter, the first relay K A1, the second relay K A2, the 3rd relay K A3, time switch, the first press button SB7, the second press button SB8, the first circuit breaker Q F1 and the second circuit breaker Q F2.As it can be seen, control circuit mainly includes four loops.In the rightmost side for Electromagnetic Valve Circuit, the controlled portion series connection of the controlled portion of the first relay, electromagnetic valve, time switch and the 3rd relay.Near Electromagnetic Valve Circuit for pressure vacuum gauge loop, connect with pressure vacuum gauge in the controlled portion of the first relay, and the lower limit contact of pressure vacuum gauge is sequentially arranged with the first terminal, the control portion of the controlled portion of the second relay and the 3rd relay electrically connects；The upper limit contact of pressure vacuum gauge electrically connects with the control portion of the second terminal block, the second relay.Specifically, the pointer of pressure vacuum gauge is open type, and time between bound, circuit disconnects.When pointer and upper limit contact or lower limit contact, circuit ON.In the left side in this loop, connect with the first press button SB7 and the second press button SB8 in the control portion of the first relay, and the controlled portion of the second press button SB8 and the first relay is in parallel, and the control portion of the first relay is in parallel with display lamp.In the leftmost side, converter is connected with motor, the second circuit breaker Q F2.First circuit breaker Q F1 is the main switch of control unit.
In a further embodiment, the controlled portion of the 3rd relay is in parallel with pressure vacuum gauge, forms a diverter branch, and after circuit ON, the electric current in pressure vacuum gauge is split to this branch road, thus plays the effect of protection pressure vacuum gauge.
In use, after equipment starts, system is automatically into automatic control system; when using point not use vacuum; vacuum in surge tank rises so that after the pressure vacuum gauge upper limit contact triggering generation signal on surge tank is to the converter in control unit, Frequency Converter Control vacuum pump is shut down；After using point to use vacuum, breaking of vacuum in surge tank, after making pressure vacuum gauge lower limit contact triggering generation signal to the converter of switch board, electromagnetic valve automatically opens up emptying, and Frequency Converter Control vacuum pump starts, and the time relay in switch board starts timing simultaneously, after the time relay arrives setting value, electromagnetic valve power-off, electromagnetic valve is automatically switched off, and vacuum system enters vacuum production status.
First close the first circuit breaker Q F1, provide power supply to equipment；Now the second press button SB8 is in open-circuit condition, and the first press button SB7 is in closure state.Pressing the second press button SB8, start display lamp bright, circuit ON triggers the first relay, the controlled portion of adhesive the first relay, i.e. switchs K1；When the pressure indication of automatic pressure controller arrives lower limit Y2, the 3rd relay is caused to be started working, adhesive switch K3, start vaccum pump motor and the electromagnetic valve of time switch countdown simultaneously, electromagnetic valve can quit work when arriving the time set；When the pressure in vacuum tank reaches upper limit Y1 set, contact closure causes the second relay to be started working, and disconnects switch K2, and while K2 open circuit, the 3rd relay quits work, and vaccum pump motor and time switch are out of service；
When the intrinsic pressure power of vacuum tank is in setting lower limit, the 3rd relay brings into operation, and starts vaccum pump motor, and startup control switch countdown, electromagnetic valve automatically opens up, and after time switch reaches the setting time, electromagnetic valve is automatically switched off.
When needing arrestment, press the first press button SB7, stop the work of the first relay, to auxiliary equipment power-off to reach the effect shut down.
As shown in Figure 3 a and Figure 3 b shows, vacuum pump is provided with muffler assembly, and muffler assembly includes deafener and silencer support, and deafener includes body 41, and the inlet union 42 that is tightly connected with body and outlet connection 48, the two ends of described body are provided with stop section 47；Described silencer support includes arc buckling parts 43, supporting part 46 integrated with arc buckling parts and reinforcement 45；Through hole 44 it is provided with, in order to be fixed in the position specified by bolt on supporting part.
Preferred implementation of the present utility model is described in detail above in association with accompanying drawing; but; this utility model is not limited to the detail in above-mentioned embodiment; in technology concept of the present utility model; the technical solution of the utility model can be carried out multiple equivalents, these equivalents belong to protection domain of the present utility model.
