Abstract
The utility model relates to an oil-gas separator which comprises a cylinder body. A filter screen is arranged in the cylinder body. A separation stop collar is arranged at one side of the filter screen. The separation stop collar is provided with oil filteration damping. A capillary tube stop collar is arranged at the other side of the filter screen. The outer wall of the capillary tube stop collar is provided with a capillary tube in a coiling mode. One end of the capillary tube is provided with an oil return filter screen, and the other end of the capillary tube is connected with an oil return port. The length of the capillary tube and the bore diameter of the oil return port can both be adjusted. Due to the fact that after mixed gas goes through separation and oil filteration once, the mixed gas is not separated completely, and then the mixed gas is separated through the filter screen and the oil filteration damping again, efficiency of oil-gas separation is improved, and also the needed return oil quantity of different compressor exhaust volumes can be achieved by adjusting the length of an inner oil return capillary tube device or the size of the bore diameter of an oil return pipe.
Description
Technical field
The utility model relates to a kind of gs-oil separator, especially for the gs-oil separator of refrigerating machine of refrigerated truck group or air conditioning for automobiles.
Background technology
Gs-oil separator is being played the part of vital role in a lot of refrigeration systems, the compressor of any kind is in operation, and oil all can be along with gas be discharged from, and oil is must be from gases at high pressure separated and return compressor.
The favourable three kinds of modes with inertia force, centrifugal force and filtration of gs-oil separator commonly used are separated.Utilize the gs-oil separator of inertia force by increasing the circulating direction that changes cold-producing medium, reduce the flow velocity of cold-producing medium, utilize the gravity difference of gaseous coolant and lubricating oil to separate, this simple in structure, but oil-dividing efficiency is poor.The gs-oil separator good separating effect that utilize to filter but complicated structure, the pressure loss is larger, and cost is higher.The gs-oil separator that utilizes the gs-oil separator of centrifugal force to compare inertia force can improve oil-dividing efficiency preferably, and cost is also low.
But the gs-oil separator of prior art exists following shortcoming: the mist of HTHP can only carry out first separation in gs-oil separator, the lubricating oil that has more droplet shape still remains in the gas, causes gaseous refrigerant and lubricating oil separation rate low; And the amount of same time period oil return is uncontrollable, does not reach required Extraction rate.
Summary of the invention
The purpose that the utility model is wanted provides a kind ofly can carry out separating for several times, improves separative efficiency, and can control the gs-oil separator of oil return speed.
For reaching above-mentioned technique effect, the technical scheme that the utility model is taked is: a kind of gs-oil separator, comprise cylindrical shell, described cylindrical shell two ends are provided with capping, level is provided with filter screen in the described cylindrical shell, the edge of filter screen and the inwall of cylindrical shell are welded and fixed, described filter screen is provided with the separation back-up ring on one side, described separation back-up ring is identical with the center line of filter screen, being weldingly fixed on the filter screen of described separation back-up ring, described separation back-up ring is provided with the oil strain damping, the another side of described filter screen is provided with the capillary back-up ring, and described capillary back-up ring is fixed in the capping, and coiling has capillary on the outer wall of described capillary back-up ring, a described end capillaceous is provided with the oil return filter screen, and the other end is connected with oil return opening; The aperture of described length capillaceous and oil return opening all can be regulated.
After taking above technical scheme, the utility model compared with prior art has the following advantages: behind the first separation oil strain, the mist that does not separate fully carries out Re-isolation by filter screen and oil strain damping, until mist is separated fully, improved the efficient of Oil-gas Separation; And according to the size of compressor displacement, regulate the size in the length of inner oil return capillary device or oil return opening aperture to reach the amount of same required oil return of time period.
Description of drawings
Fig. 1 is the structural representation of a kind of gs-oil separator of the utility model.
Among the figure: 1, import 2, upper cover 3, separation back-up ring 4, cylindrical shell 5, filter screen
6, capillary back-up ring 7, capillary 8, oil return filter screen 9, oil return opening 10, oil strain damping 11, gas outlet 12, lower capping.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Shown in Fig. 1, the utility model comprises cylindrical shell 4, described cylindrical shell 4 is provided with upper cover 2 and lower capping 12, described upper cover 2 is provided with import 1, lower capping 12 is provided with oil return opening 9, cylindrical shell 4 sides are provided with gas outlet 11, described cylindrical shell 4 interior levels are provided with filter screen 5,4 inwalls of the edge of filter screen 5 and cylindrical shell are welded and fixed, described filter screen 5 places the below of gas outlet, cylindrical shell 4 side 11, described filter screen 5 tops are provided with separates back-up ring 3, described separation back-up ring 3 is identical with the center line of filter screen 5, and the lower surface of described separation back-up ring 3 is weldingly fixed on the upper surface of filter screen 5, and the upper surface of described separation back-up ring 3 is positioned at 11 tops, gas outlet, described separation back-up ring 3 is provided with oil strain damping 10, the below of described filter screen 5 is provided with capillary back-up ring 6, and described capillary back-up ring 6 is fixed in the lower capping 12, and coiling has capillary 7 on the outer wall of described capillary back-up ring 6, one end of described capillary 7 is provided with oil return filter screen 8, and the other end is connected with oil return opening 9; The aperture of the length of described capillary 7 and oil return opening 9 all can be regulated.
The mist of compressor HTHP out separates back-up ring 3 from the import 1 of the gs-oil separator bump of entering, and changes the direction of G﹠O by the difference of centrifugal force, from different directions through filter screen 5 carry out separating first time consider oily; Then oil pass through capillary 7 oil returns because the reason of gravity is got back to the hydraulic fluid port of setting by oil return filter screen 8; The gas that does not separate fully reaches the gas flow gas outlet 11 of separating fully again by filter screen 5 and oil strain damping 10.According to the size of compressor displacement, regulate the size in the length of inner oil return capillary 7 devices or oil return opening 9 apertures to reach the amount of same required oil return of time period.
