Abstract
The invention discloses an automatic leakage detection device of a hanging evaporator, which is used for detecting whether the evaporator leaks air or not after being processed and molded and comprises a hanging arm, a gas booster pump, a leakage detection tank, a connecting pipe, a plug and a PLC (programmable logic controller). when the automatic leakage detection device is used, the connecting pipe is sleeved at one end of a pipeline of the evaporator, the other end or multiple ends of the pipeline are plugged by the plug and integrally hung on the hanging arm and sink in the leakage detection tank, then the pipeline is pressurized by the gas booster pump, so that the internal air pressure is greater than 2.8Mpa, the internal air pressure lasts for 30 minutes in the tank, if no bubble emerges, the automatic leakage detection device is qualified, otherwise, the automatic leakage detection device is unqualified.
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 PLC, when vaporizer to be measured submerges and leaks hunting pond, touch liquid-level switch, now its PLC connected starts timing, after the time (generally 30 minutes) set, controls arm and hangs out the pond translating of leaking hunting.
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, the vaporizer to be measured air-tightness in actual motion can be detected accurately, testing result is accurately and due to the control of PLC, it is achieved that automatization manipulates, and saves manpower.
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 PLC 1, described PLC 1 controls lifting and the movement of arm 3.
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.
