compressor

Abstract

The invention discloses a compressor. The compressor comprises a shell, a compression mechanism with an illumination oil passage, a motor assembly and an oil feeding mechanism. An oil pool is arranged in the shell. The compression mechanism is arranged in the shell and comprises at least one air cylinder, a crankshaft, a piston and a sliding piece, wherein the piston is arranged on an eccentric portion of the crankshaft in a sleeving mode and located in an air cylinder cavity of the air cylinder, and the sliding piece is arranged in a sliding piece groove of the air cylinder in a reciprocating mode. The motor assembly is arranged in the shell and connected with the crankshaft. The oil feeding mechanism is arranged in the shell and defines a first oil feeding cavity and a second oil feeding cavity, the second oil feeding cavity communicates with the lubricating oil passage, and the oil feeding mechanism is configured to enable the first oil feeding cavity and the second oil feeding cavity to communicate with the oil pool in a switching mode. According to the compressor, the oil sucking process of sucking oil from the oil pool and the oil supply process of supplying oil to the lubricating oil passage do not interfere with each other, the oil sucking and oil supply power is sufficient, and the lubricating effect is good.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor. Background technique [0002] The compressor mainly includes a shell, a compression mechanism and a motor assembly located in the shell. In addition, in order to lubricate, seal and cool the compression mechanism, the compressor is usually equipped with an oiling mechanism, which transfers the lubricating oil in the oil pool. It is sucked into the crankshaft through the central hole of the crankshaft, and then delivered to each friction pair through the crankshaft. [0003] The working process of the oiling mechanism generally includes the oil absorption process from the oil pool and the oil supply process toward the crankshaft. In the related technology, the oil absorption process and the oil supply process of the oiling mechanism interfere with each other, resulting in insufficient oil suction and oil supply power. The height of the lubricating oil in the oil...

Problems solved by technology

[0003] The working process of the oiling mechanism generally includes the oil absorption process from the oil pool and the oil supply process toward the crankshaft. In the related technology, the oil absorption process and the oil supply process of the oiling mechanism interfere with each other, resulting in insufficient oil suction and oil supply power. The height of the lubricating oil in the oil pool is usually high. During the operation of the compressor, there will be a problem of rotor churning oil, and during the oil absorption process of the oiling mechanism, the lubricating oil entering the crankshaft will have a backflow phenomenon. , which seriously affects the lubrication effect of the compressor
