Abstract
Bi-directional swash plate type compressor piston and piston-ring packing, relate to a kind of piston and piston-ring packing.Comprise piston, it is characterized in that: on the periphery at described piston two ends, equal interval arranges multiple tracks circular groove, multiple tracks circular groove on the periphery at piston two ends is equipped with piston-ring packing outward respectively, piston-ring packing comprises annular sleeve, annular sleeve is placed on the piston outside multiple tracks circular groove respectively, all chimeric in per pass circular groove have circular rib, and circular rib chimeric in multiple tracks circular groove is integral type structure with corresponding annular sleeve.The assembly parts that piston and rings assembly of the present utility model is integrated, piston-ring packing adopts ptfe composite to substitute current cast-iron piston ring, and its weight is only the 60-70% of homotype piston and cast-iron piston ring.Firmly during reciprocating motion, moment of inertia is little, greatly reduces the power loss of compressor, substantially increases the service behaviour of application apparatus.
Description
Technical field
The utility model relates to a kind of piston and piston-ring packing, is specially a kind of bidirectional sloping plate type vehicle air-conditioner compressor piston and piston-ring packing.
Background technique
At present, piston and piston-ring packing have two classes.One class be piston and rings with the use of, due to the cast iron quality piston ring quality weight that piston ring makes, moment of inertia during reciprocating motion of the pistons is large, and power loss is large, and energy consumption is high; Another kind of is apply in outside piston face the ptfe composite that a layer thickness is 0.02 ~ 0.10mm, but coating processes is complicated, manufacture cost is high, and a large amount of toxic gases can be produced in the fabrication process, have a strong impact on the healthy of operator and environmental pollution, and also there is coating processes complexity, manufacture cost is high.
Model utility content
The utility model object is to provide one and has weight saving, and moment of inertia is little, and power loss is little, and the bi-directional swash plate type compressor piston of the advantage such as wear-resisting, fuel-economizing, province's energy, low consumption, environmental protection and piston-ring packing.
The technological scheme realizing above-mentioned purpose is: bi-directional swash plate type compressor piston and piston-ring packing, comprise piston, it is characterized in that: on the periphery at described piston two ends, equal interval arranges multiple tracks circular groove, multiple tracks circular groove on the periphery at piston two ends is equipped with piston-ring packing outward respectively, piston-ring packing comprises annular sleeve, annular sleeve is placed on the piston outside multiple tracks circular groove respectively, all chimeric in per pass circular groove have circular rib, and circular rib chimeric in multiple tracks circular groove is integral type structure with corresponding annular sleeve.
Annular sleeve is ptfe composite, and the thickness of annular sleeve is 0.3-1.5mm.
The utility model preparation process is: the annular ring first made by ptfe composite is placed in the circular groove that piston two ends periphery is positioned at end respectively, by the coated piston be coated on completely by annular ring outside multiple tracks circular groove of heat being formed the assembly parts of integral type, the annular ring inner circumferential be coated on piston forms the multi-ring annular rib be entrenched in circular groove.
The beneficial effects of the utility model:
The assembly parts that piston and rings assembly of the present utility model is integrated, piston-ring packing adopts ptfe composite to substitute current cast-iron piston ring, and its weight is only the 60-70% of homotype piston and cast-iron piston ring.Firmly during reciprocating motion, moment of inertia is little, greatly reduces the power loss of compressor, substantially increases the service behaviour of application apparatus.
Piston group ring member adopts ptfe composite, not only has sealing effect well, improves anti-dry friction ability, and its wear resistance is better, extends the working life of compressor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises piston 1, on the periphery at piston 1 two ends, equal interval arranges multiple tracks circular groove 2, the multiple tracks circular groove 2 at piston 1 two ends is outer is equipped with piston-ring packing 3 respectively, piston-ring packing 3 comprises annular sleeve 4, annular sleeve 4 is placed on the piston 1 outside multiple tracks circular groove 2 respectively, and all chimeric in per pass circular groove 2 have circular rib 5, and circular rib 5 chimeric in multiple tracks circular groove 2 is integral type structure with corresponding annular sleeve 4.
Annular sleeve 4 is ptfe composite, and the thickness of annular sleeve 4 is 0.3-1.5mm.
