Abstract
Bi-directional swash plate type compressor piston and piston-ring packing, relate to a kind of piston and piston-ring packing.Including piston, it is characterized in that: on the periphery at described piston two ends, all interval arranges multiple tracks cannelure, it is respectively cooperating with being provided with piston-ring packing outside multiple tracks cannelure on the periphery at piston two ends, piston-ring packing includes annular sleeve, annular sleeve is placed on the piston outside multiple tracks cannelure respectively, all chimeric in per pass cannelure have circular rib, and circular rib chimeric in multiple tracks cannelure is integral type structure with corresponding annular sleeve.The molectron that the piston and rings assembly of the present invention is integrated, piston-ring packing uses 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.When living motion again, moment of inertia is little, greatly reduces the power loss of compressor, substantially increases the service behaviour of application apparatus.
Description
Technical field
The present invention relates to a kind of piston and piston-ring packing, be specially a kind of bidirectional sloping plate type vehicle air-conditioner compressor piston and piston-ring packing.
Background technology
At present, piston and piston-ring packing have two classes.One class be piston and rings with the use of, the cast iron quality piston ring quality weight made due to piston ring, moment of inertia during reciprocating motion of the pistons is big, and power loss is big, and energy consumption is high；Another kind of is to cover, in outside piston topcoating, the ptfe composite that a layer thickness is 0.02～0.10mm, but coating processes is complicated, manufacturing cost is high, and substantial amounts of toxic gas can be produced in the fabrication process, have a strong impact on the healthy of operator and environmental pollution, and it is complicated to there is also coating processes, manufacturing cost is high.
Summary of the invention
It is an object of the present invention to provide one and have weight saving, 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 technical scheme realizing above-mentioned purpose is: bi-directional swash plate type compressor piston and piston-ring packing, including piston, it is characterized in that: on the periphery at described piston two ends, all interval arranges multiple tracks cannelure, it is respectively cooperating with being provided with piston-ring packing outside multiple tracks cannelure on the periphery at piston two ends, piston-ring packing includes annular sleeve, annular sleeve is placed on the piston outside multiple tracks cannelure respectively, all chimeric in per pass cannelure have circular rib, and circular rib chimeric in multiple tracks cannelure is integral type structure with corresponding annular sleeve.
Annular sleeve is ptfe composite, and the thickness of annular sleeve is 0.3-1.5mm.
Processing technology of the present invention is: the annular ring first made by ptfe composite is placed in piston two ends periphery respectively and is positioned at the cannelure of end, being coated with by heat and annular ring is coated on molectron completely that form integral type on the piston outside multiple tracks cannelure, the annular ring inner circumferential being coated on piston forms the multi-ring annular rib being entrenched in cannelure.
Beneficial effects of the present invention:
The molectron that the piston and rings assembly of the present invention is integrated, piston-ring packing uses 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.When living motion again, moment of inertia is little, greatly reduces the power loss of compressor, substantially increases the service behaviour of application apparatus.
Piston set ring assemblies uses ptfe composite, not only has sealing effectiveness well, improves anti-dry friction ability, and its wearability is more preferable, extends the service life of compressor.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the present invention includes piston 1, on the periphery at piston 1 two ends, all interval arranges multiple tracks cannelure 2, it is respectively cooperating with being provided with piston-ring packing 3 outside the multiple tracks cannelure 2 at piston 1 two ends, piston-ring packing 3 includes annular sleeve 4, annular sleeve 4 is placed on the piston 1 outside multiple tracks cannelure 2 respectively, and all chimeric in per pass cannelure 2 have circular rib 5, and circular rib 5 chimeric in multiple tracks cannelure 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.
Claims (2)
1. bi-directional swash plate type compressor piston and piston-ring packing, including piston, it is characterized in that: on the periphery at described piston two ends, all interval arranges multiple tracks cannelure, it is respectively cooperating with being provided with piston-ring packing outside multiple tracks cannelure on the periphery at piston two ends, piston-ring packing includes annular sleeve, annular sleeve is placed on the piston outside multiple tracks cannelure respectively, and all chimeric in per pass cannelure have circular rib, and circular rib chimeric in multiple tracks cannelure is integral type structure with corresponding annular sleeve.
