Abstract
The utility model relates to a power unit for a vacuum pressure stabilization system. The power unit comprises two dry vacuum pumps, a PLC (programmable logic controller) control device and a control cabinet, wherein the PLC control device is connected with the dry vacuum pumps, the control cabinet is connected with the PLC control device, the two vacuum pumps are respectively parallelly connected on both sides of the PLC control device, the two vacuum pumps are connected through a T-shaped air suction pipe, branches of the T-shaped air-suction pipe for connecting the two vacuum pumps are respectively provided with an electromagnetic valve for controlling the air flow rate of the air suction pipe, and the electromagnetic valves are connected with the PLC control device through a circuit. The power unit for the vacuum pressure stabilization system disclosed by the utility model can be kept running stably by the two dry vacuum pumps which are arranged in parallel, when one pump has abnormal conditions, the other pump can be automatically switched to, and the power unit continues to run normally; and the air flow rate can be effectively controlled through the electromagnetic valves, therefore the detection accuracy is improved.
Description
Technical field
The utility model relates to the air atom detection range, relates in particular to a kind of propulsion system of vacuum voltage-stabilizing system.
Background technology
Toilet and clean production field are higher to the api request in the environment, and therefore, in order to detect airborne dust particle situation in real time, people carry out sample detecting at the higher field sensor installation pick-up unit of this api request degree to air; Because the influence of fluctuations of air-flow is bigger in the air, thereby causes gas flow to be subject to barometric pressure effect, and sampled data is affected.In order to stablize air pressure, people install the vacuum voltage-stabilizing system at sensor detecting device and come steady air flow.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of vacuum voltage-stabilizing system propulsion system that the vacuum voltage-stabilizing system provided vacuum power are provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of vacuum voltage-stabilizing system propulsion system, comprise dry vacuum pump, the PLC control device that is connected with dry vacuum pump and the switch board that is connected with the PLC control device, described vacuum pump has two, be attempted by the both sides of PLC control device respectively, connect by "T"-shaped exhaust tube between described two vacuum pumps, and connect and respectively be provided with a solenoid valve that is used for control exhaust tube gas flow on the exhaust tube branch road of two vacuum pumps, and this solenoid valve is connected with the PLC control device by circuit.
Compared with prior art, usefulness of the present utility model is: this vacuum voltage-stabilizing system propulsion system can guarantee working stability by two and the dry vacuum pump that connects, when unusual condition appears in a pump, can automatically switch to the another one pump and continue operate as normal, can effectively control gas flow by solenoid valve, improve and detect accuracy of detection.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model vacuum voltage-stabilizing system propulsion system perspective view;
Fig. 2 is vacuum voltage-stabilizing system propulsion system vertical views.
Among the figure: 1, dry vacuum pump; 2, switch board; 3, solenoid valve; 4, exhaust tube; 5, PLC control device.
Embodiment:
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
Fig. 1, a kind of vacuum voltage-stabilizing system propulsion system shown in Figure 2, comprise dry vacuum pump 1, the PLC control device 5 that is connected with dry vacuum pump 1 and the switch board 2 that is connected with PLC control device 5, described dry vacuum pump 1 has two, be attempted by the both sides of PLC control device 5 respectively, connect by "T"-shaped exhaust tube 4 between described two dry vacuum pumps 1, and connect and respectively be provided with a solenoid valve 3 that is used for control exhaust tube 4 gas flows on exhaust tube 4 branch roads of two dry vacuum pumps 1, and this solenoid valve 3 is connected with PLC control device 5 by circuit.
This vacuum voltage-stabilizing system propulsion system can guarantee working stability by two and the dry vacuum pump that connects; During use, work by switch board 2 and PLC control device control dry vacuum pump 1, when unusual condition appears in one of them pump, can automatically switch to the another one pump and continue operate as normal, and by solenoid valve 3 effective gas flows of controlling dry vacuum pumps 1 suction, improve and detect accuracy of detection.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
