Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of automotive air intake pipe air tightness detection equipment as shown in Figure 1, comprises frame 1, the tank 2 be arranged in frame 1, jacking gear 4 and the monitor station 3 that moves up and down with jacking gear 4, and this equipment also comprises gas source interface 6 and control device 7.Monitor station 3 also comprises pressure transducer, and pressure transducer is integrated on described reduction valve 35; Pressure transducer is electrically connected with control device 7, with pressure feedback signal difference in testing process before control device 7 detects according to pressure transducer, judges the impermeability of draft tube 8 to be measured.Fig. 2 is the structural representation of shown monitor station 3 embodiment 1; Monitor station 3 comprises the fixture 33 for fixing draft tube 8 to be measured be arranged on base 31, and fixture 33 one end is provided with plug 32, and the other end is provided with aerating device 34; Plug 2 front end is also provided with the rubber plug matched with draft tube 8 caliber to be measured.Aerating device 34 is also provided with vent valve, and vent valve is electrically connected with control device 7.Aerating device 34 is connected with gas source interface 6 by reduction valve 35; Be connected with lifting hydraulic cylinder 36 above aerating device 34, aerating device 34 moves up and down under lifting hydraulic cylinder 36 drives; Control device 7 is electrically connected with described jacking gear 4, aerating device 34 and lifting hydraulic cylinder 36 respectively.Aerating device 34 front end is also provided with the rubber plug matched with draft tube 8 caliber to be measured; Aerating device 34 front center is also provided with gas-filled tube.Fig. 3 is the structural representation of shown monitor station 3 embodiment 2; As different from Example 1, its plug 32 is connected with plug 32 one end and is connected with hydraulic cylinder; Move toward draft tube direction under Driven by Hydraulic Cylinder, better can block the tube head of draft tube 8 to be measured, impermeability is better.The fixture 33 of embodiment 2 is electric fixture, and fixture 33 is electrically connected with control device 7.Electric fixture is prior art, can adopt electronic brave bench vice or electromagnetic clamp etc.This outer frame 1 is also provided with rain glass 5, and rain glass 5 is connected with aerating device 34 by pipeline.Control device 7 also comprises display screen, for showing testing result.Control device 7 is conventional PLC or embedded scm.
The course of work of the present utility model is: draft tube 8 to be measured is put into the fixture 33 of monitor station 3 by (a), and clamps; Plug (32) is blocked one end of draft tube 8 to be measured; B () starts lifting hydraulic cylinder 36, aerating device 34 compresses one end of draft tube 8 to be measured downwards, and passes into pressurized air; C () starts jacking gear 4, monitor station 3 moves in tank 2 down, until draft tube to be measured 8 is flooded completely; D () is detected, whether artificial observation has bubble; E () starts jacking gear 4, monitor station 3 shifts out tank 2 and resets; Start lifting hydraulic cylinder 36, aerating device 34 upwards leaves draft tube 8 to be measured and is vented; F plug 32 is withdrawn by (), and unclamp fixture 33, complete draft tube to be measured is taken out, completes air-leakage test.It is 0.5 ~ 1MP that wherein said step (b) passes into pressurized air, and duration of ventilation is 120 ~ 180 seconds, makes pipe fitting air tight under 200KPa pressure in gas pressure test.
In addition by arranging pressure transducer and vent valve can realize not using in pond, just air-leakage test can be realized.The gas that control device 7 controls in reduction valve 35 pairs of sources of the gas reduces pressure, gas flows to reduction valve 35 by gas source interface 6, reduction valve 35 reduces pressure to the gas flowing through its place pipeline according to the Pressure reducing ratio of setting, reduction valve 35 is integrated with pressure transducer, and pressure transducer can by post-decompression gaseous tension signal feedback to control device 7.Flow in the aerating device 34 of monitor station 3 through the post-decompression gas of reduction valve 35 along pipeline, because pressure transducer position communicates with aerating device 34 and draft tube to be measured 8, pressure transducer can detect the air pressure in draft tube 8 to be measured, and with electric signal feed back control system 7.Gaseous tension in this signal and the draft tube to be measured 8 before detecting contrasts by control device 7, if both differences exceed allowed band, control device 7 judges that draft tube 8 to be measured exists impermeability problem, and sends to display to show the air leakage after calculating.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
