As shown in Figure 1-Figure 3, the compressor of embodiment according to a first aspect of the present invention, including housing 1 and compressor.
With reference to Fig. 1, bottom in housing 1 is provided with refrigerator oil 12, compressor is located in housing 1, and compressor includes bent axle 4, base bearing 8, supplementary bearing 9 and cylinder 5, base bearing 8 and supplementary bearing 9 are respectively provided at top and the bottom of cylinder 5, and base bearing 8, supplementary bearing 9 limit compression chamber jointly with cylinder 5, the lower end of bent axle 4 is stretched in compression chamber through base bearing 8.
nullSuch as in the example of fig. 1 and 2，It is provided with motor and compressor in the housing 1 sealed，Compressor is soaked in refrigerator oil 12，Motor is located at the top in housing 1，Compressor is positioned at the lower section of motor，Motor includes stator 2 and rotor 3，Stator 2 is fixed on the inwall of housing 1，Rotor 3 is fixed on the bent axle 4 in compressor，Thus can rotating by band dynamic crankshaft 4 when rotor 3 rotates，Compressor includes bent axle 4、Cylinder 5、Piston 6 and slide plate 7，Piston 6 is enclosed within outside bent axle 4 and rotates in cylinder 5，Cylinder 5 is provided with the vane slot 51 being slidably connected with slide plate 7，In other words，Cylinder 5 is formed the vane slot 51 radially extended，Slide plate 7 is movably arranged in vane slot 51，The two ends of cylinder 5 are respectively arranged with base bearing 8、Supplementary bearing 9，Base bearing 8、Supplementary bearing 9 and cylinder 5 surround compression chamber jointly，When motor works，Bent axle 4 can be driven to rotate，Thus driving the piston 6 being set on the eccentric part of bent axle 4 to roll along the inwall of compression chamber with compression refrigerant.
Wherein, the eccentric part of bent axle 4 meets with the ratio of the internal diameter Φ of cylinder 5 relative to the eccentric amount e of the axis of cylinder 5: 0.05≤e/ Φ≤0.12.As shown in Figure 2, eccentric amount e is the distance between the central axis of eccentric part and the axis of cylinder 5, when bent axle 4 satisfies condition relative to the eccentric amount e of cylinder 5 axis and the ratio of cylinder 5 cylinder diameter Φ: during 0.05≤e/ Φ≤0.12, it is possible to improve when compressor such as rotary compressor High Temperature High Pressure is run the wear out failure degree of slide plate 7, bent axle 4 in compressor.
With reference to Fig. 4, abscissa is the degree of wear of eccentric amount e and the degree of wear that the ratio of cylinder 5 cylinder diameter Φ, vertical coordinate are compressor and the valve seat boss 101 of compressor, exhaust valve plate 11, it can be seen that each several part abrasion reaches optimal value when satisfied 0.05≤e/ Φ≤0.12.
The such as rotary compressor of compressor according to embodiments of the present invention, by the ratio of the internal diameter Φ of eccentric amount e and cylinder 5 is arranged between 0.05≤e/ Φ≤0.12, can improve compressor High Temperature High Pressure run time compressor in slide plate 7, bent axle 4 wear out failure degree, thus not easily there is the situation of abrasion in compressor, and then effectively extend service life of compressor, improve the reliability of compressor.
In one embodiment of the invention, as it is shown in figure 1, refrigerator oil 12 is Esters oil, and Esters oil kinematic viscosity when 40 DEG C is 70.5～76.0mm2/ s, when 100 DEG C, kinematic viscosity is 8.4～9.0mm2/s.Further, refrigerator oil 12 is contained within sulfur-bearing extreme pressure anti-wear additives.Thus, by employing 40 DEG C time, kinematic viscosity is 70.5～76.0mm2/ s, when 100 DEG C, kinematic viscosity is 8.4～9.0mm2The refrigerator oil 12 of/s, lubricity when can ensure that High Temperature High Pressure and have coolant to dissolve, greatly improve the abrasion of compressor, extend the service life of compressor such as rotary compressor, and according to the compressor that eccentric amount e and cylinder 5 cylinder diameter Φ ratio are the design of 0.05≤e/ Φ≤0.12, under above-mentioned refrigerator oil 12 environment run, it is possible to significantly improve High Temperature High Pressure run time compressor in slide plate 7, bent axle 4 wear out failure degree.
Alternatively, base bearing 8 and at least one in supplementary bearing 9 are formed with steam vent 10, steam vent 10 is coated with exhaust valve plate 11.It is to say, steam vent 10 can only be formed on base bearing 8, or only formed on supplementary bearing 9, or be concurrently formed on base bearing 8 and supplementary bearing 9.Such as in the example of fig. 1 and 2, steam vent 10 is only formed on base bearing 8, and steam vent 10 runs through base bearing 8 along the vertical direction, and steam vent 10 is coated with the exhaust valve plate 11 opened with compression exhaust, thus the gas after compression can be discharged by steam vent 10.nullFurther，The side of the contiguous exhaust valve plate 11 of steam vent 10 is provided with valve seat boss 101，In other words，Valve seat boss 101 is arranged on the side surface (such as the upper surface shown in Fig. 1 and Fig. 3) contacted with exhaust valve plate 11 of steam vent 10，Valve seat boss 101 can be generally circular and coaxially arranged with steam vent 10，Specifically，The internal perisporium of valve seat boss 101 connects with the internal perisporium of steam vent 10，Or the internal perisporium of contiguous steam vent 10 is arranged，Alternatively，Steam vent 10 is circular hole，And the diameter of steam vent 10 is D，One side surface (such as the upper surface shown in Fig. 1 and Fig. 3) of the contiguous exhaust valve plate 11 of valve seat boss 101 is formed as arc surface，Now the cross section of valve seat boss 101 is arc form，Radius R >=the 1.3mm of arc surface，And 0.12≤R/D≤0.38，Thus exhaust valve plate 11 can be supported on valve seat boss 101，When meeting this condition，And when the refrigerator oil 12 of the present invention soaks under environment and the ratio of internal diameter Φ of eccentric amount e and cylinder 5 meets 0.05≤e/ Φ≤0.12，The contact wear of valve seat boss 101 itself and exhaust valve plate 11 reaches optimum state，Thus further reducing exhaust valve plate 11 situation of abrasion occurs.
Further, exhaust valve plate 11 is made up of stainless steel material, and stainless steel material comprises:
The carbon of 0.25～0.45 mass %；The silicon of 0.3～0.5 mass %；The manganese of 0.3～0.7 mass %；The phosphorus of 0～0.03 mass %；The sulfur of 0～0.015 mass %；The chromium of 12～14 mass %；The molybdenum of 0.5～2.0 mass %；And the ferrum of surplus.
