Abstract
The invention discloses a kind of automatic leak-checking apparatus of rail mounted vaporizer, for detecting whether it leaks gas after vaporizer machine-shaping, it includes head track, bottom rail, draught line, draft arm, railcar, gas boosting pump, leak hunting pond, connecting tube, plug, during use, connecting tube is enclosed within one end of evaporator pipeline, the other end or multiterminal plug block, it is integrally placed in railcar, car load is towed to leak hunting in pond, again by the supercharging in pipeline of gas boosting pump, make its air pressure inside more than 2.8Mpa, 30 minutes are continued in pond, if bubble-free is emerged, it is qualified then to check, the most defective, due to the fact that with air pressure capable of being increased slightly above the most actually used time channel interior pressure, therefore its security performance used accesses guarantee, the phenomenons such as leakage are stopped.
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 coolant, actually used process
In be not allow leakage, and in process of production, need the leak-checking apparatus produced is carried out air-leakage test, existing inspection
It is inaccurate to there is detection in survey 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 head track, bottom rail,
Draught line, draft arm, railcar, gas boosting pump, pond of leaking hunting, connecting tube, plug, described draft arm is loaded on described head track,
Described draught line is fixed on described draft arm, described in pond two opposite side that leaks hunting be inclined-plane, bottom rail from said two inclined-plane to wearing and
Crossing, described gas boosting pump is fixed on described draft arm, and one end of described connecting tube is connected with described gas boosting pump, another
End is connected with a port of evaporator pipeline to be measured, and this end of connecting tube has ferrule fitting；The described pool side that leaks hunting has quarter
Degree and liquid-level switch, described liquid-level switch connect PLC, when vaporizer to be measured be placed in railcar entrance leak hunting pond time,
Touching liquid-level switch timing, now its PLC connected starts timing, in the time (generally 30 minutes) set
After, control draft arm and tractor is pulled out pond of leaking hunting.
It is also preferred that the left there be platform and the bolt of fixing described gas boosting pump carrying described gas boosting pump on described arm
And screw.
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 detect the vaporizer to be measured air-tightness in actual motion accurately, detection
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 it is shown in figure 1, the present invention includes head track 11, bottom rail 5, draught line 10, draft arm 3, railcar 9, gas boosting pump 4, surveys
Leakage pond 8, connecting tube 6, plug, described draft arm 3 is loaded on described head track 11, and described draught line 10 is fixed on described draft arm 3
On, described in 8 liang of the pond opposite side that leaks hunting be inclined-plane, bottom rail 5 is from said two inclined-plane to wearing and mistake, and described gas boosting pump 4 is fixed on
On described draft arm 3, one end of described connecting tube 6 is connected with described gas boosting pump 4, the other end and evaporator pipeline to be measured
One port connects, and this end of connecting tube has ferrule fitting 7；There are scale and liquid-level switch 2 in described limit, pond 8 of leaking hunting, described
Liquid level 2 switch connects PLC 1.
More specifically, described draft arm 3 there are the platform carrying described gas boosting pump 4 and fixing described gas boosting pump
The bolt of 4 and screw.
These are only preferred embodiment of the present invention, therefore the scope that the present invention implements can not be limited according to this, i.e. according to the present invention
Equivalence change and the decoration that description is made, all should belong in the range of present invention covering.
