Description
Technical field
The present invention relates to Compressor Technology fields, and in particular to a kind of scroll compressor thermomechanical components and its manufacturing method and
Scroll compressor.
Background technology
Scroll compressor is as a kind of positive displacement compressor of novel, energy saving, material saving and low noise, by more and more extensive
It uses, cardinal principle is that the consecutive variations of dead volume are formed using the opposite revolution motion of dynamic and static scroll plate, to realize pressure
The purpose of contracting gas.The cooperation precision of the wherein material of orbiter and fixed scroll, machining quality and the two directly determines
It gas compression amount and then influences the Performance And Reliability of complete machine.
Demand based on energy-saving and emission-reduction, more and more orbiters and fixed scroll are all made of casting or forged aluminium at present
Alloy material.It generally, need to be to orbiter and quiet whirlpool to avoid generating adhesive wear when same type material is secondary as friction
At least one carry out surface modification treatment in capstan, but can there are problems that following three：First, by the modified component in surface
Surface forms weaker zone, will produce larger friction coefficient when the weaker zone is with the break-in in the early stage of another scroll plate.It is more tight
The situation of weight is, it is possible to since the hard particles of modified rear surface make freezing with TRANSIENT HIGH TEMPERATURE is generated when scroll plate break-in
Machine oil is carbonized, and causes to freeze deterioration of oil, to cause to seriously affect to compressor performance and reliability；Second is that compressor exists
Actual motion for a period of time after, since coating abrasion amount gradually increases, the cooperation precision of dynamic and static scroll plate and the cooperation before assembly
Precision difference is larger, this can lead to the leakage of compressed gas and then influence the performance of compressor；Third, due to compressor permanent worker
The vortex pan coating for making to cause surface modified gradually grinds off and leaks out the aluminium base of scroll plate, at this time with same type aluminium alloy conduct
Adhesive wear is easily generated when friction is with pair, two kinds of parts is made to occur to be engaged final complete machine failure.Therefore dynamic whirlpool how is reduced
The leakage of compressed gas caused by friction coefficient, reduction when capstan and fixed scroll initial stage break-in are worn due to coating avoids
Due to compressor failure caused by coating Fast Wearing, it is of great significance to the performance and reliability that improve compressor.
Chinese patent literature CN2519859Y and CN1065025C has carried out hard anode to orbiter or fixed scroll
Oxidation or anodized.But it should be noted that hard anodizing surface quality and material chemical composition, microscopic structure point
Cloth, moulding process, process for machining, condition of heat treatment etc. have much relations, higher for the accuracy requirement of reaction condition, compared with
Small condition, which changes, may lead to hard oxygen poor surface quality and cannot be satisfied reliability test requirement, and hard anodic oxygen
The roughness for changing film layer is 1-2 grades low compared with machining state, and dynamic and static scroll plate belongs to high-precision mating parts, especially scroll wrap
The high roughness in top and substrate position can all influence the gas compression amount in compression chamber, so cause the overall performance of compressor by
To influence.Although anode oxide film surface quality is slightly good, the soft of anode oxide film is also that can not change, Wu Faman
Demand of the sufficient compressor scroll plate for long-term wearability.
Chinese patent literature CN1212332A carries out Ni-P-B surface treatments to aluminium base orbiter surface, although the coating
Section hardness is higher, this kind of coating is that attachment is arranged except matrix, although its with matrix have certain adhesive force but
It is easier to fall off, and falling off the sheet coating fallen can be as the Performance And Reliability of impurity effect compressor.
Meanwhile the above mode being surface-treated for compressor orbiter or fixed scroll is required to or part needs
The operations such as one or many pickling, alkali cleaning are carried out, cause processing step cumbersome, processing procedure energy expenditure and quantity of wastewater effluent
It is larger, do not meet the environmental protection concept of energy-saving and emission-reduction.
