Abstract
The invention discloses a hanging type evaporator leak check device used for checking whether an evaporator after processing and molding leaks. The device comprises a hanging arm, an air booster pump, a leak check pool, a connection pipe and plugs. During use, the connection pipe is connected with one end of an evaporator pipeline, the other end or multiple other ends are sealed through the plugs, the whole evaporator pipeline is hung on the hanging arm and dips in the leak check pool, the air booster pump is utilized to realize pressure boosting of the pipeline to make the internal pressure be greater than 2.8Mpa, the evaporator pipeline is kept in the leak check pool for 30 minutes, if no bubble is generated, the evaporator is qualified, or the evaporator is not qualified. According to the device, the added pressure is slightly higher than the pressure of the pipeline during practical use, so use safety can be guaranteed, and liquid leakage can be prevented.
Description
Technical field
The present invention relates to art of refrigeration units, particularly relate to a kind of for detecting the bubble-tight device of evaporator pipeline.
Background technology
Vaporizer is an important device in refrigeration plant, and the flowing of its channel interior has a coolant, actually used during be not allow leakage, and in process of production, needing to carry out the leak-checking apparatus produced air-leakage test, it is inaccurate to there is detection in existing detection means, unscientific deficiency.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the present invention makes following design: present configuration: include arm, gas boosting pump, pond of leaking hunting, connecting tube, plug, described gas boosting pump is fixed on described arm, one end of described connecting tube is connected with described gas boosting pump, the other end is connected with a port of evaporator pipeline to be measured, and this end of connecting tube has ferrule fitting；Soft layer is had bottom described pond of leaking hunting, there is rubber cushion side, prevent clashing and breaking, the described pool side that leaks hunting has scale and liquid-level switch, and described liquid-level switch connects timing and alarming device, when vaporizer to be measured submerges and leaks hunting pond, touch liquid-level switch timing, starting after arriving the value set to report to the police, vaporizer can be hung out pond of leaking hunting by workman, completes detection.
It is also preferred that the left have the platform carrying described gas boosting pump and bolt and the screw of fixing described gas boosting pump on described arm.
When the present invention uses, with gas boosting pump by connecting tube and plug, improve evaporator pipeline air pressure inside to be measured, internal pressure when simulating actually used, it is possible to detecting the vaporizer to be measured air-tightness in actual motion accurately, testing result is accurate.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Embodiment one
As shown in Figure 1, the present invention includes arm 3, gas boosting pump 4, pond 8 of leaking hunting, connecting tube 6, plug, described gas boosting pump 4 is fixed on described arm 3, one end of described connecting tube 6 is connected with described gas boosting pump 4, the other end is connected with a port of evaporator pipeline to be measured, and this end of connecting tube has ferrule fitting 7；Have soft layer, side to have rubber cushion bottom described pond 8 of leaking hunting, described in the pool side that leaks hunting have scale and liquid-level switch 2, described liquid-level switch 2 to connect timing and alarming device 1.
More specifically, described arm 3 there are the platform 5 carrying described gas boosting pump 4 and bolt and the screw of fixing described gas boosting pump 4.
These are only preferred embodiment of the present invention, therefore the scope of present invention enforcement can not be limited according to this that the equivalence change i.e. made according to description of the invention content and decoration all should belong in the range of present invention covering.
