A low-wear swash plate air-conditioning compressor

Abstract

The invention belongs to the technical field of air condition compressors, and particularly relates to a low-abrasion swash plate type air conditioner compressor. The low-abrasion swash plate type airconditioner compressor comprises a shell, an air cylinder chamber, an oil storage chamber, a driving shaft, a swash plate, rolling balls, an air inlet pipe, an air outlet pipe, a buffer module and apiston assembly. The buffer module comprises an inclined block, a tension spring and an installation ring. The buffer module is installed inside the swash plate. The piston assembly comprises an upperpiston, a lower piston and a middle piston. The piston assembly is slidably installed in the air cylinder chamber. The piston assembly cooperates with the buffer module so that idle load starting-upof a compressor can be achieved. By means of the buffer module, the piston assembly can be attached to or separated from the inner wall of the air cylinder chamber. By arranging the buffer module andthe piston assembly, when the compressor is stopped, a gap is reserved between the piston assembly and the air cylinder chamber, gaps are also reserved between the swash plate and the piston assemblyas well as between the rolling balls and the piston assembly, and the gaps are closed through rotation. According to the low-abrasion swash plate type air conditioner compressor, by means of an idle load-starting up mode that the compressor is lubricated and then outputs, abrasion of components of the compressor is relieved, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning compressors, in particular to a low-wear swash plate air-conditioning compressor. Background technique [0002] The compressor is the core component of the air conditioning system, and the reliability of the air conditioning system is an important experience for customers. The cylinder block, swash plate, piston, etc. of the compressor are the key components of the compressor, and their shape and size directly affect the working quality and life of the compressor. In order to improve the service life of the compressor, it is very difficult to die-cast the cylinder bore of the compressor cylinder, the yield is low, and the processing of the cylinder has many processes, which is difficult to process and the weight of the parts is heavy; the combination of sliding shoes, steel balls and pistons , There are many matching size gears during assembly, which is easy to make mistakes.

In order to improve the service life of the compressor, it is very difficult to die-cast the cylinder bore of the compressor cylinder, the yield is low, and the processing of the cylinder has many processes, which is difficult to process and the weight of the parts is heavy; the combination of sliding shoes, steel balls and pistons , There are many matching size gears during assembly, which is easy to make mistakes

Once an error occurs, each part is a friction pair, and the oil film between the parts cannot be formed, resulting in the multiplication of the frictional resistance between the parts. The heat energy generated by the friction is high, and the power consumption of this kind of car air-conditioning compressor will increase, and the frictional resistance will be large. High heat energy will also accelerate the aging and wear of parts, and noise will follow, which not only affects the service life of the compressor, but also reduces the user experience. Therefore, the damage of the general compressor is caused by the lack of oil between the parts

[0003] In the existing swash plate compressor, due to the high viscosity and uneven distribution of lubricating oil during cold start; the parts cannot be covered with oil film, so the lubrication effect is extremely poor, resulting in serious wear, which seriously affects the service life of the compressor
