Description
Technical Field
The invention belongs to the technical field of scroll compressors, and particularly relates to a scroll compressor with an axial flexible structure.
Background
The scroll compressor is a positive displacement compression compressor, the compression part consists of a movable scroll and a fixed scroll, and the continuous change of the closed volume is formed by the relative revolution of the movable scroll and the fixed scroll in the compression process, so that the purpose of compressing gas is realized. Because the closed cavity formed when the movable vortex plate is meshed has certain gas pressure, the movable vortex plate can bear axial gas force opposite to the direction of the fixed plate during compression. In order to increase the service life of the bearing, reduce the damage of the axial force to the bearing in high-speed operation and reduce the problems of abrasion of the scroll and leakage in the compression chamber caused by unbalanced axial force, a structural design capable of balancing the axial gas force of the movable scroll is particularly necessary.
Most of the existing scroll compressor designs adopt a back pressure chamber structure, and a closed chamber is formed at the back of an movable scroll by arranging parts such as an installation frame and a shaft seal on the back of the movable scroll, and an intermediate pressure refrigerant between suction pressure and exhaust is introduced into the closed chamber, so that the movable scroll generates an axial thrust towards the fixed scroll due to the existence of gas pressure, and the axial gas force generated by a compression chamber is balanced. Due to the nature of the scroll compressor itself, the pressure within the compression chamber will fluctuate correspondingly with the angle of rotation of the crankshaft during one revolution. When the crankshaft does not rotate to the exhaust angle, the gas pressure in the compression cavity gradually rises, and when the crankshaft rotates to the exhaust angle, the gas pressure in the compression cavity gradually drops. Therefore, in a complete rotation period, the gas pressure is increased and then decreased, and therefore, the axial force of the gas applied to the movable scroll caused by the gas pressure also fluctuates. However, the pressure of the back pressure cavity of the compressor is in a constant state to a certain extent, so that when the gas pressure in the compression cavity is smaller, the back pressure born by the movable scroll is larger than the gas pressure, and the tooth top and the tooth bottom of the scroll are in a compression state, so that the running friction force is increased. When the gas pressure in the compression cavity is larger, the back pressure borne by the movable scroll is smaller than the gas pressure, and a gap state is formed between the tooth top and the tooth bottom of the scroll, so that the working efficiency of the compressor is influenced.
Therefore, a new scroll compressor with an axial flexible structure needs to be proposed to solve the problem of performance degradation of the compressor caused by large axial clearance or large axial friction force due to the fluctuation of the pressure in the scroll plate and the fluctuation of the axial clearance in the prior art.

According to an alternative embodiment of the present invention, the fixed scroll is provided with an oil hole on a compression section with the spring ring plate, when the movable scroll does not move to an angle where the oil hole is located, the spring ring plate covers the oil hole, and at this time, the oil hole is closed, and the oil outflow is limited; when the movable scroll moves to an angle where the oil hole is located, the spring ring piece is deformed downwards under the pressure of the movable scroll, at the moment, the oil hole is conducted, refrigerating machine oil flows out to the surface of the spring ring piece, and the oil is scraped to the whole movement contact surface along with the circular movement of the movable scroll on the surface of the spring ring piece, so that the bottom movement effect of the movable scroll is lubricated.
According to an alternative embodiment of the invention, the end face of the spring ring piece is provided with a coating, and the coating is made of a material with high temperature resistance, corrosion resistance and self-lubricating property of polytetrafluoroethylene and polyether-ether-ketone.

Compared with the prior art, the embodiment of the invention provides the scroll compressor with the axial flexible structure, which has the following beneficial effects:
(1) The conventional technology does not consider the fluctuation problem in one rotation period on the axial force balance problem of the movable vortex plate, and a certain mode is generally designed to apply a constant axial force on the movable vortex plate, but the existing problem cannot be well solved. The invention realizes the problem of accurately adjusting the elasticity through the creative annular eccentric groove and the spring annular sheet structure, and parts which are relatively low in cost and easy to process, thereby being beneficial to improving the working efficiency of the compressor.
(2) The suspension length of the spring ring piece at the angle of the oil hole can be precisely controlled by the opening size of the eccentric groove of the supporting seat, so that the deformation amount of the spring ring piece can be precisely controlled from the design angle, the outflow amount of the refrigerating machine oil is also controlled in a proper range, and the problem that the efficiency of the compressor is reduced due to high friction force caused by insufficient machine oil and abrasion of parts or the working efficiency of the compressor is influenced by resistance generated by stirring between more accumulated oil in the moving cavity and moving parts caused by excessive refrigerating machine oil can be prevented.
(3) The invention can also solve the problem of structural damage of the vortex wall caused by overlarge pressure between the movable vortex plate and the fixed plate under the severe working condition of the compressor. When the pressure exceeds the design allowable value, the axial force is overlarge so that the movable vortex plate can move downwards for a larger distance, at the moment, the deformation of the spring ring piece is larger, and an additional axial gap is generated in the compression cavity so that the pressure is released, so that the problem that the gas pressure exceeds the upper limit bearable by the vortex wall to cause structural damage is avoided.
(4) Compared with the prior art, the invention has the characteristics of low cost and easy installation. Compared with the design of the traditional back pressure cavity, the invention can better solve the difficulty of high sealing difficulty and high cost among different pressure cavities because of the cavities with different pressures in the compressor, and avoids the efficiency reduction of the compressor caused by internal leakage. Compared with the prior art, the invention has the advantage of lower cost. And the manner of balancing the gas force by arranging the permanent magnets as mentioned in the patent CN117386616a may have a potential problem of design failure due to a change in magnetism of the permanent magnets caused by a large amount of heat generated during the operation of the compressor, thereby causing deviation of the magnetic force from the design value. The technical scheme of the invention provides a better solution with lower material cost, more convenient assembly steps and more stable technical implementation scheme.
