In order to make those skilled in the art understand better technological scheme provided by the invention, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As Figure 1-5, the compression assembly that the embodiment of the present invention provides comprises upper flange component, cylinder 12, bent axle 13, roller 16, slide plate, lower flange assembly and lower flange cover plate 18, lower flange assembly is made up of jointly lower flange 17, lower valve, lower valve baffle plate and rivet, the middle part of lower flange 17 arranges hollow portion, to make lower flange cover plate 18 and lower flange 17 form intermediate cavity; Upper flange component is made up of jointly upper flange 11, upper valve block, upper valve block baffle plate and rivet; In order to ensure the pressure of intermediate cavity, this compression assembly is also provided with and increases enthalpy assembly 19, and this increasing enthalpy assembly 19 is connected with intermediate cavity.On upper flange 11 and lower flange 17, all offer gas port, to ensure the circulation of heat transferring medium.
The key improvements point of this compression assembly is, vane slot on cylinder 12 comprises the first vane slot and the second vane slot, accordingly, the slide plate being assemblied in vane slot comprises the first slide plate 14 and the second slide plate 15, both are installed on respectively in the first vane slot and the second vane slot, cylinder 12, roller 16, the first slide plate 14 and the second slide plate 15 form one-level compression volume and two-stage compression space, on cylinder 12, there is one-level intakeport 121, one-level relief opening 122, secondary intakeport 123 and secondary relief opening 124, one-level intakeport 121 and one-level relief opening 122 are positioned at a side of the first vane slot and the second vane slot, secondary intakeport 123 and secondary relief opening 124 are positioned at the opposite side of the first vane slot and the second vane slot.One-level intakeport 121 is communicated with the liquor separator 21 of compressor, one-level relief opening 122 communicates with intermediate cavity, secondary intakeport 123 is communicated between intermediate cavity and two-stage compression space, secondary relief opening 124 is communicated between the gas port on two-stage compression space and upper flange 11, and one-level compression volume and described two-stage compression space communicate by intermediate cavity.
After rotating, bent axle 13 drive roller 16 to roll, due to the effect of pressure difference, heat transferring medium is inhaled in the one-level compression volume of cylinder 12 by one-level intakeport 121 in liquor separator 21, heat transferring medium after overcompression enters intermediate cavity by one-level relief opening 122, with by after increasing enthalpy assembly 19 and entering another heat transferring medium in intermediate cavity and mix, enter the two-stage compression space of cylinder 12 by the gas port on lower flange 17, thereby be further compressed, finally discharge this compression assembly by the gas port on upper flange 11.
As can be seen here, the vane slot on the cylinder 12 that the embodiment of the present invention provides is two, provides two stage compression as heat transferring medium, makes heat transferring medium under the effect of single cylinder 12, obtain larger compression ratio.Visible, to introduce than background technique content, this compression assembly has improved ultralow temperature heating operation ability and the high-temperature refrigeration service requirement of compressor.
The above-mentioned compression assembly that the embodiment of the present invention provides can be applicable in single cylinder compressor, certainly also can be applicable in duplex cylinder compressor, to improve to a greater degree ultralow temperature heating operation ability and the high-temperature refrigeration service requirement of compressor.
For the set-up mode that increases enthalpy assembly 19, the embodiment of the present invention provides following two schemes: the first string as shown in Figure 4, increasing enthalpy assembly 19 is connected on cylinder 12,, on cylinder 12, be provided with and increase enthalpy mouth, increase enthalpy assembly 19 and coordinate with this increasing enthalpy mouth, so, the heat transferring medium increasing in enthalpy assembly 19 can enter in intermediate cavity by the gas port on this increasing enthalpy mouth and lower flange 17; First scheme as shown in Figure 3 and Figure 5, increases enthalpy assembly 19 and is connected on lower flange 17, on lower flange 17, arranges and increases enthalpy mouth 171, and the heat transferring medium that makes to increase in enthalpy assembly 19 directly enters in intermediate cavity by this increasing enthalpy mouth 171.In above-mentioned two schemes, when increasing enthalpy assembly 19 is connected with lower flange 17, only need on lower flange 17, process and increase enthalpy mouth 171, and without cylinder 12 is processed, therefore, this scheme can ensures the size of cylinder 12, improves the workability of this compression assembly simultaneously.In addition, increase enthalpy assembly 19 and be connected the flow process that also can shorten the heat transferring medium in increasing enthalpy assembly 19 with lower flange 17, reduce the drag losses of heat transferring medium, contribute to improve the compression efficiency of heat transferring medium.
Further, in technological scheme, the edge of above-mentioned one-level relief opening 122 is positioned at the side edge of vane slot, or the edge of secondary relief opening 124 is positioned at the side edge of vane slot, and this side edge refers to the side of vane slot and the intersection of cylinder 12 inwalls.The size that can increase the effective compression volume in cylinder 12 is so set, thereby the heat transferring medium after guarantee compression is more, discharge quickly, contributes to equally to improve the compression efficiency of heat transferring medium.
In order to improve by a larger margin the compression efficiency of heat transferring medium, in the compression assembly that the embodiment of the present invention provides, the volume of one-level compression volume is greater than the volume in two-stage compression space.The volume of this one-level compression volume refers to roller 16 and is rolled to from one-level intakeport 121 size in the space that one-level relief opening 122 forms, and the volume in two-stage compression space refers to roller 16 and be rolled to from secondary intakeport 123 size in the space that secondary relief opening 124 forms.
In preferred technological scheme, the air-breathing area of above-mentioned compression volume is greater than the leaving area of compression volume.Taking compression volume by one-level compression volume and two-stage compression spatial composing as example, now, the air-breathing area at one-level intakeport 121 places is greater than the leaving area at one-level relief opening 122 places, the air-breathing area at secondary intakeport 123 places is greater than the leaving area at secondary relief opening 124 places, be arranged so that by above-mentioned the exhaust pressure of heat transferring medium is higher, the compression efficiency of whole compression assembly will promote by a larger margin.
The compressor that the embodiment of the present invention provides comprises housing, cover assembly, lower cap assemblies, liquor separator 21, motor (being made up of rotor assembly and stator module) and the compression assembly being connected with this liquor separator 21, and this compression assembly is the described compression assembly of above-mentioned arbitrary scheme.The heat transferring medium of being discharged by compression assembly enters in the space that housing, cover assembly and lower cap assemblies form, and further discharges whole compressor by the outlet pipe being arranged on cover assembly.
