Abstract
The present invention relates to sealing propertytest field, more particularly to a kind of refrigerator heat exchanger helium inspection technique, a kind of refrigerator heat exchanger helium inspection technique comprises the following steps：S1：To again it be vacuumized after refrigerator heat exchanger jointing；S2：Qualified refrigerator heat exchanger will be vacuumized to be filled with after helium and be placed into helium inspection case progress helium inspection；S3：The refrigerator heat exchanger that helium inspection is finished carries out acceptance or rejection mark；S4：Qualified refrigerator heat exchanger is identified to step S3 to carry out helium recovery and unload lower contact, will be identified underproof refrigerator heat exchanger progress isolation and be reprocessed.A kind of refrigerator heat exchanger helium inspection technique of the present invention, with water and powerful drying plant need not be needed, by toward filling helium inside refrigerator heat exchanger, the leak detection to product can be completed in helium inspection instrument equipment, this technique has simple to operate, less demanding to employee, the advantages of measuring accuracy is high, detecting step is few, floor space is small, cost is low, detection efficiency is high and can automate propulsion.
Description
Technical field
The present invention relates to sealing propertytest field, more particularly to a kind of refrigerator heat exchanger helium inspection technique.
Background technology
Refrigerator heat exchanger is evaporator and condenser is the core component of heat exchange in refrigerator refrigeration system, if refrigerator exchanges heat
Device leak, refrigerator can be made to lose refrigeration, make whole refrigerator system can not normal work, so the device of refrigerator two manufacture complete
An important leakage detecting process can be carried out afterwards, and the leakage detecting process of prior art is substantially examined using water, but water inspection technique pair
The requirement of operating personnel is very high, and leak detection rate is very low, and the use of the professional manufactory of refrigerator heat exchanger is also not suitable at this stage.
The content of the invention
It is an object of the invention to overcome drawbacks described above of the prior art, there is provided a kind of refrigerator heat exchanger helium inspection technique.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：
A kind of refrigerator heat exchanger helium inspection technique, comprises the following steps：
S1：To again it be vacuumized after refrigerator heat exchanger jointing；
S2：Qualified refrigerator heat exchanger will be vacuumized to be filled with after helium and be placed into helium inspection case progress helium inspection；
S3：The refrigerator heat exchanger that helium inspection is finished carries out acceptance or rejection mark；
S4：Qualified refrigerator heat exchanger is identified to step S3 to carry out helium recovery and unload lower contact, will identify underproof refrigerator
Heat exchanger carries out isolation and reprocessed.
Preferably, absolute vacuum pressure is vacuumized in described step S1：≤1000Pa.
Preferably, helium inspection pressure is 1.6MPa~2.0MPa in described step S2.
Compared with prior art, beneficial effects of the present invention are：
A kind of refrigerator heat exchanger helium inspection technique of the present invention, without with water and not needing powerful drying plant, passes through past refrigerator
Filling helium inside heat exchanger, can complete the leak detection to product in helium inspection instrument equipment, this technique have it is simple to operate, to member
Work is less demanding, and measuring accuracy is high, detecting step is few, floor space is small, cost is low, detection efficiency is high and can automate
The advantages of propulsion.
Embodiment
A kind of refrigerator heat exchanger helium inspection technique, comprises the following steps：
S1：To again it be vacuumized after refrigerator heat exchanger jointing；
S2：Qualified refrigerator heat exchanger will be vacuumized to be filled with after helium and be placed into helium inspection case progress helium inspection；
S3：The refrigerator heat exchanger that helium inspection is finished carries out acceptance or rejection mark；
S4：Qualified refrigerator heat exchanger is identified to step S3 to carry out helium recovery and unload lower contact, will identify underproof refrigerator
Heat exchanger carries out isolation and reprocessed.
To ensure verification and measurement ratio, absolute vacuum pressure is vacuumized in step sl：≤ 1000Pa, in step s 2 helium inspection pressure
For 1.6MPa~2.0MPa.This technique need not use water, that is, eliminate powerful drying plant, this technique have it is simple to operate,
Less demanding to employee, measuring accuracy is high, detecting step is few, floor space is small, cost is low, detection efficiency is high and can be certainly
The advantages of dynamicization is promoted.
It is described above, it is only the preferred embodiments of the present invention, is not the limitation that other forms are done to the present invention,
Any those skilled in the art are changed or are modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But, every without departing from the present invention program content, the technical spirit according to the present invention is done to above example
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
