Description
Technical field
The invention belongs to air-conditioning parts detection range, relate in particular to air conditioner two-unit helium checking device and technology.
Background technology
Two devices of air-conditioning are that the effect of evaporator, condenser is the core component of air-conditioning heat interchange.If air conditioner two-unit leaks, can make air-conditioning lose refrigeration, make the whole air-conditioning system can't operate as normal.So after two devices machine, also have important technology technology of hunting leak exactly, the fundamental purpose of this technology is that the air conditioner two-unit anti-leak is detected, and does not have leakage to guarantee air conditioner two-unit; The leak detection technology that the air conditioner two-unit parts are commonly used is helium inspection technology, and existing common helium inspection technological process is:
1, workpiece (being evaporator part or condenser parts) flows on helium inspection streamline, and first workman is docked the detecting leakage jointing at first station with workpiece, charge into nitrogen in workpiece;
2, workpiece flows to next station, charge into after the nitrogen in the workpiece, continue for some time, second workman judges according to the variation of pressure whether the workpiece that detects has big leakage, if no big leakage, this detecting leakage jointing is taken off from workpiece, and the vacuum jointing is docked with workpiece, the air in the workpiece is drained only;
3, workpiece moves to next station again, and the 3rd workman takes off the vacuum jointing from workpiece, and will fill the helium jointing and dock with workpiece, charges into helium in workpiece;
4, workpiece moves to next station again, and helium charges into after the workpiece, and the 4th workman closes the helium jointing, charges into helium workpiece afterwards and enters further detection in the vacuum helium inspection case.
This shows, in the prior art, helium inspection technology with the detecting leakage in the helium inspection process, vacuumize, fill operation such as helium and fully separately carry out, the per pass operation is by manually finishing on helium inspection streamline separately, this helium inspection technology exists following problem:
1, production efficiency is on the low side, in the helium of workpiece inspection technology, needs repeatedly jointing (detecting leakage jointing, vacuumize jointing, fill the helium jointing) dock with workpiece or group following, makes production efficiency extremely low;
2, the helium inspection is second-rate, product quality is unreliable, the per pass operation is finished by manually-operated fully, important technical parameters, as dwell time, gas charge pressure and other parameters, rely on the people for controlling fully, be subjected to the influence of many-sided factor easily and cause important technical parameters to be guaranteed fully, thereby omission occurs easily, the generation of abnormal conditions such as flase drop;
3, labor strength height needs when the workman operates repeatedly jointing to be carried out plug, and the plug jointing needs bigger power and needs to observe detection case, working strength of workers height;
4, comprehensive manufacturing cost height because its production efficiency is on the low side, causes costs such as human cost in the two device parts production runes and charges for water and electricity higher.
Summary of the invention
The object of the present invention is to provide a kind of production efficiency is higher, labor strength is lower air conditioner two-unit helium checking device and technology.
