The normal operation of system.
The content of the invention
In view of this, it is necessary to which crushing can be offset by providing one kind, ensure the negative pressure mouth negative tube consistent with pressure at blower fan
Road system.
The technical solution adopted in the utility model：A kind of negative-pressure pipeline system, it is characterised in that including blower fan, negative tube
Road, negative pressure mouth, axial id fan, first pressure sensor, second pressure sensor and controller, the blower fan are arranged at described
Negative-pressure pipeline one end, the negative pressure mouth are arranged at the negative-pressure pipeline other end, and the axial id fan is arranged at the negative pressure
On pipeline, the first pressure sensor is arranged at that the negative pressure is intraoral, and the second pressure sensor is arranged at the negative pressure
Pipeline connects one end of the blower fan, and the controller and the first pressure sensor and the second pressure sensor are automatically controlled
Connection.
Preferably, the angle that the negative-pressure pipeline is formed with the negative pressure mouth is 90 °~180 °.
Preferably, the negative-pressure pipeline, the negative pressure mouth, the axial id fan, the first pressure sensor, described
The quantity of second pressure sensor and the controller is equal and at least two.
Preferably, the controller includes signal receiving module, comparison module and axial id fan drive module.
The beneficial effects of the utility model：Axial id fan is set on negative-pressure pipeline, mended by the air inducing of axial flow blower
Fill, have the function that to supplement negative pressure, so as to ensure that the pressure at the pressure of negative pressure mouth and blower fan is consistent, meanwhile, by setting
Pressure sensor and controller are put, the Automated condtrol of whole system can be achieved.
Brief description of the drawings
Fig. 1 show the attachment structure schematic diagram of negative-pressure pipeline system in the utility model.
Fig. 2 show the connection block diagram of controller in the utility model.
Fig. 3 show the attachment structure schematic diagram of second embodiment in the utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing, example is served only for explaining the utility model, and
It is non-to be used to limit the scope of the utility model.
As shown in figure 1, be a kind of negative-pressure pipeline system 100 in the utility model, including blower fan 10, negative-pressure pipeline 20,
Negative pressure mouth 30, axial id fan 40, first pressure sensor 50, second pressure sensor 60 and controller 70.The blower fan 10
Described one end of negative-pressure pipeline 20 is arranged at, for producing negative pressure in the negative-pressure pipeline 20, the negative pressure mouth 30 is arranged at institute
The other end of negative-pressure pipeline 20 is stated, for connecting the mechanism for needing negative pressure to be operated, the negative-pressure pipeline 20 and the negative pressure mouth
30 angles formed are 90 °~180 °, to ensure to reduce bend loss as far as possible.The axial id fan 40 is arranged at the negative pressure
On pipeline 20, its role is to be acted on by air inducing, the negative pressure at the negative pressure mouth 30 is supplemented.The first pressure sensor 50
It is arranged in the negative pressure mouth 30, it is described for detecting the instant pressure value at the negative pressure mouth 30 and forming the first electric signal
Second pressure sensor 60 is arranged at one end that the negative-pressure pipeline 20 connects the blower fan 10, for detecting at the blower fan 10
Instant pressure value and formed the second electric signal.The controller 70 and the first pressure sensor 50 and the second pressure
Sensor 60 electricly connects.
Specifically, as shown in Fig. 2 the controller 70 includes signal receiving module 71, comparison module 72 and axle stream air inducing
Machine drive module 73, the signal receiving module 71 are used to receive first electric signal and second electric signal, the ratio
It is used to judge whether first electric signal is less than second electric signal compared with module 72, if judged result is first telecommunications
Number being less than second electric signal, then the axial id fan drive module 73 starts to drive the axial id fan 40 to work,
Supplement the negative pressure at the negative pressure mouth 30.
Due to the device that needs to be operated using negative pressure system in workshop often more than one, therefore to meet actual production
Need, optimize whole negative pressure system, and reduce the cost of negative pressure system, a blower fan 10 can be shared by multiple negative pressure systems,
Second embodiment of the present utility model is simply introduced in the case of this, as shown in figure 3, the negative-pressure pipeline 20, the negative pressure mouth
30th, the axial id fan 40, the first pressure sensor 50, the second pressure sensor 60 and the controller 70
Quantity is 3, and various components described above supports the use to form a plurality of negative pressure branch road one by one, then shares same blower fan 10, each negative
Pressure branch road can realize pressure controlled Automated condtrol by the controller 70 on the branch road.
The beneficial effects of the utility model：Axial id fan is set on negative-pressure pipeline, mended by the air inducing of axial flow blower
Fill, have the function that to supplement negative pressure, so as to ensure that the pressure at the pressure of negative pressure mouth and blower fan is consistent, meanwhile, by setting
Pressure sensor and controller are put, the Automated condtrol of whole system can be achieved.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
