Description
Technical field
The present invention relates to a kind of automobile-used scroll compressor, especially a kind of automobile-used scroll compressor of big discharge capacity, specifically a kind of vortex compressor for large displacement vehicle of taking back oily device.
Background technique
At present, scroll compressor is very a kind of rapidly idle call compressor of development in recent years, it has the rotating speed height, proper functioning under the deep-fried twisted dough sticks spare can lacked, long service life, easy to maintenance simple, shortcoming is under existence conditions, compare with big discharge capacity reciprocal compressor, the Base radius maximum of existing separate unit vortex compression only be 3 millimeters, molded lines height maximum below 33 millimeters, substantially for dilly, can satisfy usage requirement, and for motor bus and similarly have refrigeration heat request higher occasion, existing separate unit scroll compressor can't meet the demands at all, for this reason, the claimant once proposed to use mode that two scroll compressors are installed in parallel to satisfy the vehicle usage requirement, this method has solved the use problem of scroll compressor on large vehicle to a certain extent, but also there is complex structure in the long run in this method, installation takes up room greatly, rate of fault is the double of separate unit compressor, cost is relatively than problems such as height, and therefore developing big discharge capacity scroll compressor is the task of top priority.
Because the characteristics of big discharge capacity scroll compressor, understanding some machine oil in its working procedure is entered in the hyperbaric chamber by quiet dish discharge with the refrigeration agent after compressing, though and can be deposited into the bottom of hyperbaric chamber along with some machine oil of unexpected release of pressure, but still have relatively large machine oil to enter in the air-conditioning system with refrigeration agent, accumulate over a long period, machine oil content in the whole air-conditioning system is more and more, causes heat exchange efficiency to descend, and can influence the proper functioning of compressor when serious.Simultaneously because a large amount of consumption of low-pressure cavity machine oil, cause the compressor lubrication oil starvation, the wearing and tearing of transmission part have been aggravated, for this reason except installing additional the gas and oil separating plant in quiet dish exhaust ports, also the oil that is separated must be sent in the low-pressure cavity and recycle for lubricating once more, and according to the knowledge of the applicant, the machine oil of no-trump hyperbaric chamber collection is still sent into the device and the technology appearance of low-pressure cavity at present, even therefore realized Oil-gas Separation, if can not in time the machine oil of separating be sent back in the low-pressure cavity, it still can enter in the air-conditioning system under the effect of high pressure, cause heat exchange efficiency to descend, lubricated can't the obtaining of moving element in time replenished, and this problem must be overcome.
Summary of the invention
The objective of the invention is to design and a kind ofly both the machine oil safety that is deposited on after the Oil-gas Separation in the hyperbaric chamber can be delivered to low-pressure cavity in time, can the pressure of hyperbaric chamber not exerted an influence again simultaneously, help improving the lubrication effect of compressor again, improve the vortex compressor for large displacement vehicle of taking back oily device of heat exchange efficiency.
Technological scheme of the present invention is:
A kind of vortex compressor for large displacement vehicle of taking back oily device, comprise casing 1, Moving plate 2, quiet dish 3, bent axle 4, casing 1 is separated into hyperbaric chamber 6 and low-pressure cavity 7 by quiet dish 3, quiet dish 3 is provided with the exhaust port 8 that connects hyperbaric chamber 6 and low-pressure cavity 7, low-pressure cavity 7 is connected with suction port 9, hyperbaric chamber 6 is connected with relief opening 10, Moving plate 2, the main body of quiet dish 3 and bent axle 4 is arranged in casing 1, Moving plate 2 is installed on the end of bent axle 4, the other end of bent axle 4 stretches out outside the casing 1 and links to each other with driving wheel 11, Moving plate 2 inserts in the quiet dish 3, the hyperbaric chamber of quiet dish 3 communicates with exhaust port 8, it is characterized in that in hyperbaric chamber 6, being provided with long-pending oil sump 12, long-pending oil sump 12 communicates with low-pressure cavity 7 by oil return capillary tube or the pore 13 that passes on the quiet dish 3 that is arranged in long-pending oil sump 12, under the effect of suction and discharge difference of height, the refrigerator oil of collecting in the long-pending oil sump 12 infiltrates in the low-pressure cavity 7 by capillary tube or pore 13 at leisure, as long as the aperture design of capillary tube or pore 13 is become with oil impregnate pressure to match, just can both realize oil impregnate, realize the pressurize of hyperbaric chamber 6 again.Long-pending oil sump 12 has been formed oil return apparatus of the present invention with oil return capillary tube or pore 13.
In order to match with above-mentioned oil return apparatus, the present invention is equipped with gas and oil separating plant 14 in hyperbaric chamber 6, on the exhaust port 8, to improve oil gas separation, reduce the machine oil content in the pipeline, improves heat exchange efficiency.Gas and oil separating plant 14 is by the separating plate relative with exhaust port 8 141 and enclose and place the filter screens 142 at exhaust port 8 periphery places to form.
The Moving plate 2 of big discharge capacity scroll compressor of the present invention can be 34～60 millimeters with the molded lines height of quiet dish 3, and its Base radius can be 3.6～7 millimeters.
Beneficial effect of the present invention:
1, solved the outlet of machine oil after the Oil-gas Separation, the moving element that both can be in the low-pressure cavity provides lubrication oil, can guarantee the pressure in the hyperbaric chamber again, can increase substantially heat exchange efficiency.
2, solved that machine oil content has increased problem in the air-conditioning system along with the prolongation of service time, can make the machine oil in the air-conditioning system maintain a very low level, improve the heat exchange efficiency of complete machine, can improve the lubrication state of compressor moving element simultaneously, reduce noise, life-saving.
3, the molded lines height of compressor and Base radius have all been realized historical breakthrough, and then the discharge capacity of separate unit compression has also realized historical breakthrough synchronously, lay a good foundation for large vehicle uses the separate unit scroll compressor, can improve the heat pump performance of such vehicle, reduce total noise of centrifuge.
4, simple in structure, easily manufactured.
