The fault of a pipeline system of the refrigerator can be repaired, the quality of the repairment can be ensured, and the important operating technical parameters of the refrigerator can be detected by the detector for a refrigerator. The utility model can not only be used for repairing various refrigerators, but also can be used for repairing air conditioners and automotive air conditioners.
Description
The utility model relates to the detector that refrigerator (comprising air-conditioning) maintenance is used.
At present, the sales volume of refrigerator enlarges day by day, as refrigerator, air-conditioning etc., brings heavy day by day burden to maintaining unit, and the maintenance level of existing maintaining unit and the reason that ability can not improve are to lack a kind of scientific and reasonable, easy to use, instrument that can guarantee repair quality.For example, the fault of refrigerator often is more common in the leakage of cooling duct system and obstructed, and this just must will change additional refrigeration agent--freon.For household refrigerator, the can amount of requirement freon must be in the margin of error of standard volume 3%, must suction fall the residual refrigeration agent of being infiltrated by foreign gas, moisture content etc. in the pipeline, what of can amount can influence the work of refrigerator greatly, only depend on seeing by rule of thumb, listen to touch, estimate and can not reach requirement, guarantee repair quality.In addition, the can to automobile, air-conditioning needs comprehensive equipment with test.
Task of the present utility model is to solve to aspirate former refrigeration agent, but the problem of quantitative filling new refrigerant is particularly designed the instrument that can repair air-conditioning, car air conditioner etc., not only wants to check out the refrigerator fault, the refrigerator fault can also be detected, the technical order and the quality of refrigerator can also be detected.
Technical solution of the present utility model is: with a kind of evacuator and quantitative filling condensing agent device, pipeline connects in the following manner: refrigerator conduit entrance (1,2,3) connect vacuum pump or connect vacuum pump compressor pump in parallel with it, another Lu Lianxiang cryogen vessel pipeline of conduit entrance through valve.As the need quantitative filling, can on the cryogen vessel pipeline, connect a certain amount of level meter.Quantitatively level meter can be that transparent material is made, as the heavy sheet glass pipe.A refrigeration agent storage pipeline can also be set again to be connected to the refrigerator conduit entrance, repair air-conditioning with this filling device, but can is different from the refrigeration agent of refrigerator, perhaps can also be used for the agent of can automobile air-conditioning refrigeration, can connect the high pressure pipe line import of car air conditioner with this pipeline.On the can pipeline gas manometer can be installed.Perhaps said apparatus can also with following arbitrary two, three or all device be combined into an integrated instrument: 1) thermometric instrument can be common thermoscope, as glass-stem thermometer, also can be a temperature meter (electronic thermometer), with numeral or pointer demonstration.2) leak detector device: but adapted has commercially available product, as halide leak detector to freon sensor sensitive probe.3) clock apparatus and the performance devices that starts to work of survey refrigerator start/stop time, clock can be ordinary clock and watch, electroclock, preferably the electroclock of controlling with relay.In addition, but adapted one desk fan uses (simulated automotive operation of air conditioner working state) during for the auto repair air-conditioning.
Utilize the utility model, can make the maintenance instrument of the special purposes of various differences, can also comprehensively become an instrument, for example: the instrument of single auto repair air-conditioning equipment, only need electric fan, vacuum pump, compressor pump, and two road freon dress is irritated interface (1,2).The instrument of repairing window air conditioner and refrigerator can be without compressor, as long as low pressure or negative pressure dress are recorded cryogen.Instrument all can be installed on the movable stand.The utility model instrument can be checked out the leakage of refrigerator cooling duct and joint, accurate can condensing agent, also can measure refrigerator and freeze room temperature, measure refrigerator power consumpiton and starting performance, this instrument is easy to use, move easily, can finish refrigerator overhaul task, be a kind of more scientific and reasonable instrument, has very big popularizing value, can use for refrigerator manufacturer special repair point and other freezing repair shop especially, to guarantee the high quality maintenance.
The utility model is described in further detail below in conjunction with accompanying drawing with by embodiment, and Fig. 1 is the suction one filling device schematic representation of suction and filling device schematic representation, particularly integrated repair car air conditioner, refrigerator, other air-conditioning.Car air conditioner high pressure pipe line import (1) connects to air filter (L by valve
1) and compressor pump (HP), barometer (b
1) range to 15 kilograms per centimeter
2, vacuum pump (P) can be in parallel with (HP), connects car air conditioner low pressure pipeline import (2), barometer (b
2) range can be in-760～5 kilograms per centimeter
2Another connects refrigerator conduit entrance (3), connect to level meter (4) through pipeline and valve, (4) can be heavy wall glass garden tube makes, show the volume indicating graduation on the wall, also can on level meter, post the table of comparisons that varying environment temperature and different model refrigerator need add volume of the cooling medium, use cryogen vessel (F with convenient
12) can be through a filter (L
2) connecting system again.(b
3) be that liquid-sighting glass is with observation can situation directly perceived.It uses roughly as is following: find time, during the can car air conditioner, high pressure and low pressure pipeline import meet (1), (2), pass (V respectively
3), open all the other valves, drive vacuum pump, (b
1, b
2) indication negative pressure time proof will manage in refrigerant pump, leak detector is hunted leak, can refrigeration agent again after the soldering closes (V
1), open (V
3), start compressor pump (HP), observe barometer (b
1, b
2) indication and the interior liquid storage filling of car liquid-sighting glass, can gets final product when extremely an amount of.When repairing refrigerator, compressor pump (HP), filter (L
1) gas manometer (b
1) can, the refrigerator pipe joint connects (3), the same operation, after with (V
3) open, (V
4) close, make refrigerant (F
12) flow to level meter (4) regulation scale, put into the refrigerator pipeline again, at last with valve (V
