Abstract
The invention discloses a vacuum pressure stabilizing system power apparatus. The apparatus comprises dry vacuum pumps, a PLC control device connected with the dry vacuum pumps, and a control cabinet connected with the PLC control device, the number of the vacuum pumps is two, the vacuum pumps are connected to two sides of the PLC control device in parallel, the two vacuum pumps are connected through a T-shaped air exhaust tube, air exhaust tube branches connecting the two vacuum pumps are respectively provided with a solenoid valve used for controlling the gas flow of the air exhaust tube, and the solenoid valve is connected with the PLC control device through a line. The vacuum pressure stabilizing system power apparatus can guarantee stable work through the two parallel-connected dry vacuum pumps, so when one of the pumps abnormally runs, automatic switching to the other one of the pumps is carried out, and the other one continuously runs normally; and the gas flow can be effectively controlled through the solenoid valves, and the detection precision is improved.
Description
Technical field
The present invention relates to the air atom detection field, relate in particular to a kind of propulsion system of vacuum steady voltage system.
Background technology
Toilet and clean production field are higher to the api request in environment, and therefore, in order to detect in real time airborne dust particle situation, 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 in air is larger, thereby cause gas flow to be subject to barometric pressure effect, sampled data is affected.In order to stablize air pressure, people install vacuum steady voltage system at sensor detecting device and come steady air flow.
Summary of the invention
Technical matters to be solved by this invention is that a kind of vacuum steady voltage system propulsion system that vacuum steady voltage system provided vacuum power are provided.
in order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of vacuum steady voltage 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 respectively the both sides of PLC control device, 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 controlling the 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 invention is: this vacuum steady voltage 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 normal operation, can effectively control gas flow by solenoid valve, improve and detect accuracy of detection.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of vacuum steady voltage system propulsion system of the present invention perspective view;
Fig. 2 is a kind of vacuum steady voltage system propulsion system vertical view.
In figure: 1, dry vacuum pump; 2, switch board; 3, solenoid valve; 4, exhaust tube; 5, PLC control system.
Embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
Fig. 1, a kind of vacuum steady voltage 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 vacuum pump 1 has two, be attempted by respectively the both sides of PLC control device 5, connect by "T"-shaped exhaust tube 4 between described two vacuum pumps 1, and connect and respectively be provided with a solenoid valve 3 that is used for controlling exhaust tube 4 gas flows on exhaust tube 4 branch roads of two vacuum pumps 1, and this solenoid valve 3 is connected with PLC control device 5 by circuit.
This vacuum steady voltage system propulsion system can guarantee working stability by two and the dry vacuum pump that connects; During use, control the work of dry vacuum pump 1 by switch board 2 and PLC control device, when unusual condition appears in one of them pump, can automatically switch to the another one pump and continue normal operation, and effectively control the gas flow of dry vacuum pump 1 suction by solenoid valve 3, improve and detect accuracy of detection.
It is emphasized that: above is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
