Abstract

The invention relates to the technical field of refrigeration compressors, in particular to a rotary compressor with a spiral oil guide sheet. In the rotary compressor, the lower end of the rotating shaft of a motor is connected to an inner bore oil duct of an oil bath; the inner bore oil duct is provided with the spiral oil guide sheet; the spiral thread pitch of the lower end of the spiral oil guide sheet is less than the thread pitch of the upper side of the spiral oil guide sheet; in the working process of the compressor, when the oil level of lubricating oil in the oil bath is lower, theoil guide sheet at the lower end of the spiral oil guide sheet which has smaller thread pitch is contacted with the lubricating oil in the oil bath, and the working angle of the oil guide sheet is large so as to contribute to increasing the oil supply and oil supply pressure; and in the process of delivering the lubricating oil upwards, the upper spiral sheet of the spiral oil guide sheet has larger thread pitch, so that the formation frequency of eddy of oil flow is reduced, oil supply resistance is reduced, the quantity of oil reaching an oil hole level is high, the quantity of oil enteringa compressor unit from an oil hole is higher, sufficient oil is supplied to the compression unit, and the reliability of the compressor is ensured.

Description

technical field

[0001] The invention relates to the technical field of refrigeration compressors, in particular to a rotary compressor provided with a spiral oil guide plate. Background technique

[0002] The compressor is the core equipment for compressing the refrigerant in the air conditioning system to make it participate in the cycle. The rotary compressor is a commonly used compressor. The rotary compressor generally includes a rotary compressor and a swing compressor. The rotary compressor is in a sealed shell A motor, a cylinder body assembly and an eccentric compression unit are provided, and the rotating shaft of the motor drives the eccentric compression unit to work in the cylinder of the cylinder body assembly.

[0003] In order to lubricate the eccentric compression unit, an inner hole oil passage connected to the oil pool is provided on the rotating shaft, and an oil hole connected to the eccentric compression unit is arranged horizontally on the inner hole oi...
