Abstract
A test method for leakage of spare parts includes charging gas with a certain pressure then to be sealed entirely or partly by a sealing bag with small hole on it, then putting them aside for a period of time. A probe of the detector is put between spare parts and sealing bag through the small hole to test the leakage which can quickly test the leakage of spare parts with high accuracy and little investment, to reach vacuum hydrogen test level even through at unfavorable conditions, very mush suitable for leakage detection of spare parts of evaporators, small sealed pipes and containers of air-conditioners, gas containers.
Description
The present invention relates to a kind of leak hunting method of container, particularly a kind of leak hunting method to parts such as A/C evaporator, small-sized closed conduit and airtight containers.
At present, the leak hunting method of container is had a variety of, as the inspection of vacuum helium, water inspection and high-low pressure inspection etc., but all there is weak point in these detection methods: wherein helium inspection cost is very high, and the water inspection is then examined less than little leakage, during high-low pressure leak detection operating cost and accuracy not high.
The objective of the invention is provides a kind of quick, high-accuracy, parts leak hunting method cheaply for overcoming above-mentioned shortcoming.
Purpose of the present invention can be achieved as follows: the leak hunting method of these parts comprises following processing step: earlier charge into certain pressure to the parts of needs leak detection and can be detected the detected gas of device; With sealing bag described parts are carried out hermetically sealed or semitight then, but the aperture of opening and closing is wherein arranged on the sealing bag; At last, parts and sealing bag placed a period of time after, the aperture of detecting head on sealing bag of detector put in the detection of hunting leak in the space that forms between parts and the sealing bag.
The present invention realizes leak detection to parts by the cooperation that utilizes sealing bag and detector probe, but fast detecting goes out the leakage situation of parts, the accuracy of leak detection height, and equipment investment cost is very low, even under comparatively disadvantageous condition, also can reach the level of vacuum hydrogen inspection.Therefore, be very suitable for using in the leak detections of manufacturer to the little parts of evaporator, small-sized closed conduit and airtight container equal-volume such as air conditioner, gas container.
The present invention is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the synoptic diagram of parts of the present invention when sealing with sealing bag.
In Fig. 1, the parts 1 that hunt leak are A/C evaporators.At first, the evaporator of needs leak detection is charged into the gas R12 of certain pressure size, wherein pressure is generally 0.8-2.0MPa, the gas that charges into should guarantee to be detected device and detect and to obtain, as select for use: gases such as R12, R22, R134a, R407C, R410A, helium, or the mixed gas of these gases also can, the evaporator after will inflating is simultaneously hung on chain.Then, be enclosed within outside the evaporator with sealing bag 2, and it is tight that the sack of sealing bag 2 is tied envelope, make evaporator be placed in the sealing bag 2 by hermetically sealed, wherein sealing bag 2 is with impermeability good soft thin-walled material such as plastics, nylon films etc. are made the sack shape, sack can be set up bungee or elastic cord, to be used to tighten the sack sealing, a bit big or longilineal for volume especially by the leak detection thing, can only need by bungee should be by the semitight of leak detection thing, soon the position that might leak seals up, and need not hermetically sealedly to live whole object and get final product, but sealing bag 2 is provided with the detecting head turnover of the aperture of opening and closing for detector simultaneously.Behind the good seal, sealing bag and evaporator are hung in together and are transferred a segment distance on the chain, promptly after after a while, as 3-15 minute, promptly just be on the streamline together or the time of two procedures, the aperture of detecting head on sealing bag with the halogen detector puts in the confined space that forms between sealing bag and the evaporator again, surveys the R12 gas that its interior air has or not trace, just can finish the technological process of leak detection.The precision of detecting leak gas of this method depends on the precision and the sensitivity of the detecting head of detector, when needs detect little leakage, selects for use precision and highly sensitive detecting head to get final product.
The same substantially with the leak detection step of above-mentioned evaporator for other parts as the leak detection processing step of small-sized closed conduit or airtight container.
Claims (1)
1, a kind of leak hunting method of parts is characterized in that: the leak hunting method of described parts comprises following processing step: earlier charge into certain pressure to the parts (1) of needs leak detection and can be detected the detected gas of device; Use sealing bag (2) that described parts (1) are carried out hermetically sealed or semitight then, wherein sealing bag (2) but be provided with the aperture of opening and closing; At last, after placing a period of time in parts (1) and the sealing bag (2), the aperture of detecting head on sealing bag (2) of detector put in the detection of hunting leak in the space that forms between parts and the sealing bag.
