Description
Technical field
The utility model relates to a kind of gs-oil separator of air-conditioning system.
Background technology
In air-conditioning system, when refrigerant is discharged from compressor, often Partial shrinkage machine lubricating oil is taken away.Therefore need to increase gs-oil separator in systems in which, oil is separated and is back to compressor, ensure that compressor lubrication is normal.Gs-oil separator is divided into horizontal and vertical, and wherein vertical oil separator is more with centrifugal separation, namely utilizes the density contrast of gaseous refrigerant and lubricating oil, and lubricating oil centrifugation power is large thus be separated.During Oil-gas Separation, after gas enters separator, oil content separator wall retrains, and first transfers circular motion to by rectilinear motion, and the rotary gas overwhelming majority is spinned down motion vertically, and moves towards separator wall, Here it is outer whirlpool.At this moment density larger oil droplet particle be thrown toward separator wall, by with the colliding again and again of wall, the loss of momentum is complete, and falls into oil drain out along with the outer whirlpool of gas and be separated.Simultaneously outer whirlpool makes peripheral gas pressure raise, is formed centrally low-pressure area in the separator, when a certain position, gas arrival cylindrical shell bottom, in center set, upwards to spin motion with identical direction of rotation, Here it is interior whirlpool.The not separated oil of part also discharges together with gas.Outer whirlpool pressure is high, and interior whirlpool pressure is low.Therefore, the separative efficiency feature of variant oil droplet size is: particle is less, and it is longer, more difficult separated to follow gas time; Speed is higher, and centrifugal force is larger, more separated.
Centrifugal oil-air separator structure in current air-conditioning system, as shown in Fig. 1-1 and Fig. 1-2, comprises cylindrical shell 1, inner barrel 2 and inlet baffle 100, and its underpart is oil export 101, and top is entrance 102, and top is gaseous coolant outlet 103.The oil droplet particle separation diameter of this Oil-gas Separation is generally 10 μm ~ 100 μm.To less than 10 μm, especially the olesome separative efficiency of less than 3 μm is low.And refrigeration system is in low temperature underload situation, and lubricating oil in the refrigerant solubility is low, and refrigerant velocities is low, and lubricating oil cannot be followed cold-producing medium and be got back to compressor, therefore a large amount of lubricating oil is stored in evaporimeter, therefore requires high to separative efficiency.But because speed is low, existing gs-oil separator separative efficiency is poorer, cannot meet now separative efficiency requirement, inside needing to increase separator, refrigerant flow rates is to improve centrifugal force, thus improves separative efficiency.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of gs-oil separator that can improve the air-conditioning system of oil-gas separation efficiency.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of gs-oil separator of air-conditioning system, comprise outlet(discharge) flange, inner barrel, hold-down support, inlet flange, entrance, liquid-sighting glass, oil outlet, cylindrical shell, pressure tap and chassis, described inlet flange is connected with air-conditioning system blast pipe, described chassis is provided with cone, seamless link inside the top of described cone and cylindrical shell, bottom is fixed by internal stent.
The bottom of cone described in the utility model is provided with oil leaking hole.
On cone distance cylindrical shell described in the utility model, lateral extent is 0.8 ~ 5.0 times of barrel diameter, and the cone angle of described cone is 5 ° ~ 25 °, and the height of described cone is 0.5 ~ 5 times of barrel diameter.
The utility model compared with prior art, increases cone and can improve rotating speed thus short grained oil droplet is more easily separated.In identical 10m/s entrance velocity situation, existing oil content cylindrical shell place refrigerant flow rates is 33m/s, only can be separated more than 8 μm olesomes, be separated 1 μm ~ 3 μm of olesomes efficiency lower.The refrigerant flow rates of the utility model conical section is increased to 43.8m/s, 100% can be separated the olesome of more than 4 μm, and also have higher separative efficiency to the olesome of 1 μm ~ 3 μm.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in Fig. 2-1, Fig. 2-2, the gs-oil separator of the utility model air-conditioning system, comprise outlet(discharge) flange 5, inner barrel 2, hold-down support 6, inlet flange 8, entrance 7, entrance guiding plate 12, liquid-sighting glass 9, oil outlet 10, cylindrical shell 1, pressure tap 11 and chassis 3, chassis 3 is provided with cone 4, seamless link inside the top of cone 4 and cylindrical shell 1, bottom is fixed by internal stent.Wherein, inlet flange 8 is connected with blast pipe, and outlet(discharge) flange 5 is connected with condenser, and isolated lubricating oil gets back to compressor by oil outlet 10.
As shown in Fig. 4-1, the bottom of cone is provided with oil leaking hole 13.
On the utility model cone distance cylindrical shell, lateral extent is 0.8 ~ 5.0 times of barrel diameter, and the cone angle of cone is 5 ° ~ 25 °, and the height of cone is 0.5 ~ 5 times of barrel diameter.
The utility model use time, inlet flange is connected with air-conditioning system blast pipe, refrigerant superheat gas and lubricating oil liquid mixture from compressor out after blast pipe, more successively pass through inlet flange, entrance.Afterwards, do the screw toward backspin in inner barrel after refrigerant gas part enters cylindrical shell, after cone base, because diameter diminishes, gas is accelerated, then the screw of upwards revolving, and is finally passed into condenser in outlet.Oil droplet part is then that the power that is more early centrifuged that particle is larger is got rid of on cylindrical shell wall, separated from the gas.Particle is less, and the time of following gas is longer, more difficult separation.Oil droplet granule is screwed into cone and is accelerated under following gas, centrifugal force also becomes large, is therefore more easily separated.Finally only have few granule oil droplet along with refrigerant gas is toward exit movement, after most oil is split into wall, get back to compressor to oil outlet.Increase cone can improve rotating speed thus short grained oil droplet is more easily separated.
In the 10m/s entrance velocity situation run with air-conditioning conventional load, the speed of existing gs-oil separator and the utility model cylindrical shell is more or less the same, and all at about 33m/s, but the refrigerant flow rates of the utility model conical section is increased to 43.8m/s, add 32%, thus improve separative efficiency.
For air-conditioning system entrance velocity 5m/s when underload cold operation, increase cone inside cylindrical shell after, cylindrical shell speed is about 5.5m/s, the utility model cone place speed 7.5m/s.The speed at its cone place improves 36% than existing oil content, thus improves separative efficiency.
The oil-gas separation efficiency contrast effect that entrance refrigerant flow rates is respectively 5m/s and 10m/s is as shown in the table.From table, correction data can illustrate that the separative efficiency of the utility model under conventional operating mode and low temperature running on the lower load all improves, the especially granule oil droplet of 1 ~ 5 μm.
