Description

A kind of compressor of air conditioner orbiter

Technical field

The utility model relates to compressor of air conditioner orbiter technical fields, and it is dynamic to particularly belong to a kind of compressor of air conditioner use Scroll plate.

Background technique

Screw compressor because its high-efficient, small in size, light weight, low noise, run smoothly be widely used in air-conditioning and In refrigeration unit.The fixed scroll of existing screw compressor is provided with scroll wrap on bottom plate, and orbiter is arranged on end plate There is scroll wrap.Two scroll plates engage assembly in opposite directions, and orbiter moves under the promotion of crankshaft, are held by being sequentially reduced compression chamber Product, compression enter the fluid in working chamber.Since the friction pair of electric scroll compressor Moving plate and antifriction metal (AFM) piece is a kind of flat Dynamic friction, and generally directly contacted by aluminum alloy coating with antifriction metal (AFM) piece, coefficient of friction is big, plates under long-time high temperature, high pressure Layer is easy to fall off, and restricts the service life of motor compressor machine mechanical part always.

Utility model content

The purpose of the utility model is to provide a kind of compressor of air conditioner orbiters, overcome the prior art not Foot.

To solve the above problems, technical solution adopted in the utility model is as follows:

A kind of compressor of air conditioner orbiter, including orbiter and wear ring, the back side of the orbiter are set There are wear-resisting annular groove, bearing groove, pin arrangement slot and counterweight tank, the bearing groove is located at the center of orbiter, described Pin arrangement slot be distributed in the circumference external symmetry of bearing groove, the counterweight tank is described to move positioned at pin arrangement slot between It is equipped with wear-resisting annular groove scroll plate back outer circle week, wear ring is installed in the wear-resisting annular groove.

Further, the wear ring includes becket and abrasion resistant fibrous layer, and the abrasion resistant fibrous layer is sprayed at metal On the surface of ring.

Further, the abrasion resistant fibrous layer is the compound of polytetrafluoroethylene fibre or polytetrafluoroethylene fibre and carbon fiber One of fiber.

Further, the abrasion resistant fibrous layer with a thickness of 20-30um.

Further, there are six the pin arrangement slot is set.

Further, there are three the counterweight tank is set, between the pin arrangement slot adjacent positioned at four.

Compared with prior art, the implementation result of the utility model is as follows: the friction of abrasion resistant fibrous layer Coefficient is low, and wear-resisting property is good, is coated with the wear ring of abrasion resistant fibrous layer in the back side mounting surface of orbiter, can directly avoid Contact of the orbiter with drag ring, wear orbiter will not, and after wear ring is worn, wear ring can be more It changes, has saved maintenance cost.
