5) calculate differential pressure of atmospheric pressure and drop to time spent of 100Pa from 200Pa, if the time spent greater than 10 seconds, then impermeability meets the requirements, otherwise, do not meet.
Described step 2) and the step of the gas leakage situation that detects in addition air hole one, air hole two between the step 3) respectively and between the ventilating joint one, ventilating joint two, when detecting when finding the gas leakage situation is arranged, do mending-leakage and process, until without gas leakage.
The present invention compares with prior art, novel structure, simple, be tightly connected with two air holes that the chamber door of container both sides are diagonal position respectively with the test section by the part of exerting pressure with pick-up unit, be specially and utilize vacuum pump to exert pressure from the air hole one of container, and the air hole two of container connected microbarographs, thereby the differential pressure of atmospheric pressure situation according to microbarograph, judge whether the container impermeability meets the impermeability requirement, this pick-up unit and method have no effect to the structure of container self, can be adapted to the occasion of various use containers; In addition, detection method of the present invention is not only time saving and energy saving, and operation is very simple, convenient, and testing result accurately, reliably is worthy of popularization.
[description of drawings]
Fig. 1 is structural representation of the present invention;
Among the figure: 1, draft tube 2, vacuum pump 3, container 4, wireway 5, microbarograph 6, ventilating joint 1, air hole 1, air hole 29, ventilating joint two.
[embodiment]
Further specify below below in conjunction with accompanying drawing the present invention being done:
As shown in Figure 1, the present invention includes: exert pressure part and test section, the part of exerting pressure comprises draft tube 1 and vacuum pump 2, the be tightly connected gas outlet of vacuum pump of the inlet end of draft tube, the outlet side of the draft tube ventilating joint 1 that is tightly connected, the test section comprises wireway 4 and microbarograph 5, the inlet end of the wireway ventilating joint 29 that is tightly connected, the outlet side of the wireway microbarograph that is tightly connected, vacuum pump, microbarograph are by the line connection control system, and control system comprises control module, timing module and display module.
When the device and method among the present invention is applicable to Inter-fumigation of Container Cargo quarantine processing the container impermeability is judged, its principle of work is to formulate with reference to the air-tightness detection method of Australia and standard and according to the stifling reality of work situation of China, easy and simple to handle comparatively speaking, detect accurately.Employed equipment is: vacuum pump, draft tube, microbarograph, wireway, detection syringe needle, stopwatch, double faced adhesive tape, ventilating joint, patching panel etc.
Can carry out in accordance with the following steps the bubble-tight detection of container among the present invention:
One, obviously not meeting impermeability requires: whether enter in the container, close chamber door of container, observing container body has obvious printing opacity, if container body badly broken, printing opacity is obvious, then need not detect, and can judge directly that the container impermeability is undesirable.
Two, do not belong to above-mentioned when obviously not meeting impermeability and requiring when container, its detecting step is as follows:
