Description
Technical field
The utility model relates to a kind of proving installation of R600a refrigerator freezing machine oil kapillary plugging rate, belongs to the testing apparatus technical field.
Background technology
In recent years, due to the development of environmental protection, power-saving technology, the R600a cold-producing medium becomes the main replacement scheme of R12, and the Energy Efficiency Ratio of compressor (COP value) also progressively rises to nearly 2.0 from 1.0, and heavy duty detergent R600a compressor has become the mainstream product in the market.
Heavy duty detergent R600a compressor is compared at aspects such as thermodynamics, dynamics very large difference is arranged with the R12 compressor.Under standard condition, the discharge pressure 12.7bar of R12 compressor, load is relatively heavier, and in order to guarantee the reliability of long-time running, the R12 compressor generally adopts the higher lubricating oil of viscosity such as ISO-22, ISO-32; And the discharge pressure 7.6bar of R600a compressor, load is relatively light, for reducing friction loss, raising the efficiency, generally adopts the low-viscosity oils such as ISO-10, ISO-7, ISO-5.In refrigeration cycle, because R600a and refrigerator oil have good intermiscibility, refrigerator must have parts of lubricating oil and enter cooling cycle system when work, although the internal circulating load of lubricating oil is less, but for a long time in refrigeration cycle, the materials such as greasy, the impurity produced in lubricating system can follow lubricating oil to enter in refrigeration system, at the capillary wall place, deposit, change the roughness of capillary tube inner wall, in serious situation, more can cause capillary inner diameter to diminish, flow resistance increases, thereby causes refrigeration performance to descend.
The proving installation of existing capillary flow rate is to carry out the nitrogen flow test for new kapillary, draws the pressure-dependent a kind of relation of gas flow capillaceous, for the quality inspection of the design of refrigeration system and coupling and kapillary batch production provides support.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of proving installation of R600a refrigerator freezing machine oil kapillary plugging rate.The refrigerator freezing machine oil kapillary plugging rate method of testing that the utility model relates to, be applicable to the test of R600a refrigerator freezing machine oil kapillary plugging rate, and freezer compressor lubricant oil is mineral type refrigerator oil.
A kind of proving installation of R600a refrigerator freezing machine oil kapillary plugging rate, gas cylinder connects air strainer, the other end connected electromagnetic valve of air strainer, the other end of solenoid valve connects boost gauge and pressure-regulating valve, other end Bonding pressure sensor, precision pressure gauge and second solenoid valve of pressure-regulating valve, the other end quality of connection flowmeter of the second solenoid valve, the other end of mass flowmeter connects kapillary.
The utility model can be tested R600a refrigerator freezing machine oil kapillary plugging rate, efficiently and accurately.
The accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to following, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is R600a refrigerator freezing machine oil capillary flow detector structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of proving installation of R600a refrigerator freezing machine oil kapillary plugging rate, gas cylinder 1 connects air strainer 2, the other end connected electromagnetic valve 3 of air strainer 2, the other end of solenoid valve 3 connects boost gauge 4 and pressure-regulating valve 5, the other end quality of connection flowmeter 9 of the other end Bonding pressure sensor 6 of pressure-regulating valve 5, precision pressure gauge 7 and the second solenoid valve 8, the second solenoid valves 8, the other end of mass flowmeter 9 connects kapillary 10.
A kind of proving installation of R600a refrigerator freezing machine oil kapillary plugging rate, select the refrigerator oil N10-1 of dark refining depth naphthenic base oils allotment and the refrigerator oil N10-2 of shallow refining depth naphthenic base oils allotment.
A kind of operation of proving installation of R600a refrigerator freezing machine oil kapillary plugging rate is as follows:
Before test, kapillary is rinsed well with clean-out system, and clean with nitrogen blowing; Cleaning solvent for new test compressor is cleaned at least 3 times, will test after compressor inside dries up with nitrogen, total interface jam-pack rubber stopper is stand-by;
Kapillary is accessed to the capillary flow tester, and kapillary should be the straight tube access as far as possible, and as the limitation because of proving installation, kapillary must be the plate-like bending, and crooked least radius must not be less than 300mm.Inflow direction by nitrogen marks end to end capillaceous;
Kapillary is completed rear access freezer compressor accelerated life test device.According to the oil product charge weight test oil sample of packing into of test compressor, access freezer compressor accelerated life test device.
As mentioned above, embodiment of the present utility model is explained, but, as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation also all is included in protection domain of the present utility model.
