Oil way lubrication system and compressor

Abstract

The embodiment of the invention discloses an oil way lubrication system and a compressor. According to the oil way lubrication system, lubricating oil is conveyed to a first oil inlet and a second oil inlet through an oil tube by virtue of a hydraulic pump, the lubricating oil in the first oil inlet enters an air cylinder, is used for lubricating a piston in a compression cavity and returns through a second oil outlet, and the lubricating oil in the second oil inlet enters a crankshaft and is used for lubricating an oil way channel through the second oil outlet and lubricating a gap between a connecting rod and the crankshaft through a third oil outlet. Compared with the prior art, fixed-point oil supply is realized by adopting the oil way lubrication system disclosed by the embodiment of the invention, the oil lubrication requirement of a friction pair is guaranteed, the oil way lubrication system is simply arranged, a complex process is avoided, therefore, the oil way lubrication system has the advantage of high reliability, large-scale speed operation of the compressor can be realized, the cold quantity change range is greatly enlarged, and the fault probability is reduced.

Description

technical field [0001] The invention relates to the technical field of belt transmission, and more specifically relates to an oil lubricating system and a compressor. Background technique [0002] In compressors with oil lubrication, the reliability of oil lubrication has an important impact on the normal operation of the compressor. Once the oil lubrication system fails, the friction pair of the compressor will be partially lubricated, or there will be no oil lubrication, resulting in severe wear and the compressor cannot work. [0003] Currently, see figure 1 The oil circuit system of the oil-lubricated compressor includes oil pump 2, crankshaft 5, cylinder block 7, connecting rod, oil pump 2, crankshaft 5, cylinder block 7, motor rotor 3, motor stator 4, etc. to form the core of the compressor. The core is arranged inside the shell 1, and the bottom of the shell 1 forms an oil pool 11 for containing lubricating oil. When working, under the pumping action of the oil pum...

Problems solved by technology

[0004] At present, oil-lubricated compressors generally use centrifugal pumps or screw oil pumps to supply oil to the compressors, such as figure 2 As shown, however, whether it is a centrifugal pump or a screw pump, there are strict requirements on the speed of the compressor. Once the speed cannot be satisfied, the oil lubrication system will fail; in addition, in order to smoothly pump the lubricating oil to the top of the crankshaft 5, The peripheral surface of the crankshaft 5 is processed with connected oil holes and oil grooves 503, wherein the oil inlet 501 communicates with the oil outlet 22 of the oil pump 2, the oil inlet 21 of the oil pump 2 communicates with the oil pool, and the oil outlet 502 of the crankshaft communicates with the oil pool. The oil guide hole of the connecting rod 6 is connected, such as image 3 As shown, the processing of the crankshaft 5 is relatively difficult, and many oblique holes and spiral oil grooves 503 need to be processed, and the production process is complicated.

Once the crankshaft is worn, the oil supply of other friction pairs will fail, resulting in the failure of the entire oil lubrication system

Moreover, the paths passed by the oil lubrication system are all the main friction pairs of the compressor, and the probability of failure is high
