Please also refer to the fitting structure schematic diagram that Fig. 3-5, Fig. 3 is gas-liquid separator in Fig. 2; Fig. 4 is the structural representation of Fig. 3 middle outlet pipe; Fig. 5 is the partial enlarged drawing at A position in Fig. 4.Wherein, the structures such as the not shown cylindrical shell of Fig. 3, upper cover and low head, represent outlet and inlet tube, the position of discharge connection and annexation with clear.
The entrance point of outlet 26 has in trumpet-shaped introduction segment 261, and as shown in Figure 3, the port diameter of this introduction segment 261 is greater than the pipe diameter of outlet 26.
During work, gas-liquid mixture enters from inlet tube 24, utilizes sudden enlargement aisle spare that its flow velocity is reduced, change flow direction, by gravitational settling, liquid refrigerant sinks simultaneously, be stored in the inner chamber of cylindrical shell 21, gaseous refrigerant floats, after entering outlet 26 from the entrance point of outlet 26, derive from discharge connection 25, through spill port, due to siphonage, draw appropriate lubricating oil, enter compressor together with gaseous refrigerant, lubrication is played to compressor.
In the program, owing to being provided with introduction segment 261 at the entrance point of outlet 26, the port diameter of this introduction segment 261 is greater than the pipe diameter of outlet 26, when volume flow one timing, reduce in the relative background technology of flow velocity after gaseous refrigerant enters outlet 26, correspondingly, the pressure loss of gaseous refrigerant also reduces, thus the power consumption of compressor can be reduced, improve system energy efficiency.
Wherein, the analysis of causes of the pressure loss reduction of gaseous refrigerant is as follows:
In formula:
Δ Pk---the pressure loss;
K---pressure drop coefficient;
V---flow velocity;
γ---coefficient of friction;
D---caliber;
ω---volume flow.
When medium one timing, coefficient of friction γ is definite value; If pressure drop coefficient K certain (relevant with physical dimension), from formula (1), pressure loss Δ Pk and flow velocity v square are directly proportional, and namely flow velocity v is less, and Pk is less for pressure loss Δ; From formula (2), volume flow ω mono-timing, caliber d increases, then flow velocity v reduces.
Arrange although the port of export of the entrance point of outlet 26 and inlet tube 24 staggers, entering from inlet tube 24 to avoid gas-liquid mixture completely directly enters in outlet 26 afterwards, this gas-liquid separator is also provided with air-guide part 27, to be separated by the entrance point of the port of export of inlet tube 24 and outlet 26.
On this basis, outlet 26 can be fixed with air-guide part 27, with effective stationary exit pipe 26, prevents outlet 26 from producing in system operation and rocks.
In concrete scheme, outlet 26 is fixed by introduction segment 261 and air-guide part 27, particularly, can adopt welding manner, reliably easy.
Because introduction segment 261 is horn-like structure, the contact of itself and air-guide part 27 is point cantact, comparatively difficult during welding, when specifically arranging, can punching press one is tangent with outlet 26 tube wall on introduction segment 261 planar portions 261a, as shown in Figure 5, introduction segment 261 is welded with air-guide part 27 by this planar portions 261a, and means of spot welds is converted into face welding, bonding area increases, both convenient welding, can increase weld strength again.
Certainly, actual when arranging, the tube wall of planar portions 261a and outlet 26 is not tangent is also feasible, as long as the axis being parallel of planar portions 261a and introduction segment 261 is arranged, guarantees that the face between planar portions 261a with air-guide part 27 contacts, to increase weld strength.
In above-mentioned each scheme, the tube wall of introduction segment 261 and the axis angle of introduction segment 261 can be chosen within the scope of 40 ° ~ 50 °.So, effectively the pressure loss can be reduced.
Analyze as calculated, when the angle of the tube wall of introduction segment 261 and the axis of introduction segment 261 is 45 °, significantly can reduce the pressure loss, the pressure loss is minimum, when arranging so actual, the axis angle of the tube wall of introduction segment 261 and introduction segment 261 preferably can be set to 45 °.
In above-mentioned each scheme, the main body of outlet 26 is actual in syphon shape, and namely outlet 26 comprises bend loss 262 and the introduction segment 261 from bend loss 262 extension, and the visual actual conditions of concrete curved shape of bend loss 262 need to arrange.
When specifically arranging, the pipe diameter d of bend loss 262 can be set to 15mm ~ 25mm, and on this basis, the port diameter D of introduction segment 261 can be set to 1.1 ~ 1.2 with the ratio of the pipe diameter d of bend loss 262; So, the pressure loss in gas-liquid separator can be reduced further, improve gas-liquid separation effect further.
When specifically arranging, the pipe diameter d of bend loss 262 also can be set to 15mm ~ 18mm, and on this basis, the port diameter D of introduction segment 261 preferably can be set to 1.2 ~ 1.3 with the ratio of the pipe diameter d of bend loss 262; So, the pressure loss in gas-liquid separator can be reduced equally, improve gas-liquid separation effect further.Please refer to Fig. 3, and composition graphs 6 is understood, Fig. 6 is the structural representation of air-guide part in Fig. 3.
In concrete scheme, air-guide part 27 comprises a base plate 271 and three baffle plates, 272, three baffle plates 272 are affixed with three sides of base plate 271 respectively, forms the square structure with top end opening 27a and side opening 27b.
When arranging, the port of export port of inlet tube 24 is corresponding with top end opening 27a position, and the introduction segment 261 of outlet 26 is affixed with the outer wall of baffle plate 272.Particularly, outlet 26 is welded and fixed by aforesaid plane portion 261a and baffle plate 272.
So, after gas-liquid mixture enters from inlet tube 24, directly enter the space that three baffle plates 272 and base plate 271 surround, due to the obstruct of three baffle plates 272, gas-liquid mixture can only flow out from side opening 27b.
Be appreciated that any one being fixed in three baffle plates 272 of the introduction segment 261 of outlet 26 all can play and intercept the effect that gas-liquid mixture directly enters outlet 26.
When the introduction segment 261 of outlet 26 is fixed in baffle plate 272 outer wall relative with side opening 27b, gaseous refrigerant after separation needs to walk around the baffle plate 272 adjacent with side opening 27b and is allowed for access in outlet 26, that is, gaseous refrigerant needs through baffling in the inside of gas-liquid separator, can increase the pressure loss; When the introduction segment 261 of outlet 26 is fixed in baffle plate 272 outer wall adjacent with side opening 27b, compared with the former, the glide path baffling of gaseous refrigerant is relatively little, the pressure loss is less, when arranging so actual, preferably outlet 26 is fixed in baffle plate 272 outer wall adjacent with side opening 27b.
Further, baffle plate 272 has flanging 2721, so, after gas-liquid mixture can be avoided to flow out from inlet tube 24, enters in outlet 26 because of rebuffed splashing.
Certainly, actually to arrange, also the port of export of inlet tube 24 can be stretched into the inner chamber of air-guide part 27 through top end opening 27a, be rebuffed after flowing out to avoid gas-liquid mixture and splash and enter outlet 26.
