Problems solved by technology

[0017] However, when the oil 61 in the lower part of the tank 10 is mixed with a liquid medium, since the specific gravity of the liquid medium at 15 degrees Celsius is 1.24, the specific gravity of the oil 61 is 0.195, so the liquid medium is located at the bottom, so it may occur that the oil in the first oil supply hole 63 The case where only liquid medium flows
[0018] At this time, the scroll compressor is started, and the liquid medium is supplied to the rotating scroll shaft 25 and the upper frame 54 through the oil suction upper hole 65, and the contact part and other contact parts are in contact, causing the lubricity of the contact part to be destroyed instantly.

Embodiment Construction

[0048] The oil supply device of the scroll compressor of the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0049] image 3 It is a longitudinal sectional view of a scroll compressor equipped with an oil supply device according to an example of the present invention. Here, the same symbols are used for the same parts as those in the prior art.

[0050] like image 3 As shown, the structure of the scroll compressor is as follows: there is a closed space inside the casing 10; the compression part 20 is installed inside the casing to compress the medium; the electric motor part 50 provides driving force for the compression part 20; the lubricating part 160 lubricates The inside of the box 10.

[0051] One side of the box body 10 has a suction pipe 11 for sucking in the medium from the outside and a discharge pipe 12 for discharging the compressed medium.

[0052]The compression part 20 is composed of a fixed scro...

Abstract

An oil supply unit of vortex-type compressor features that beside the first oil supply unit for supplying oil to the rotary shaft via its internal sucking-up oil hole, the second oil supply unit higher than the first one is used for higher lubricating performance.

Description

technical field [0001] The invention relates to an oil supply device for a scroll compressor. Background technique [0002] Generally speaking, the scroll compressor is a kind of rotary compressor, which is a positive displacement compressor with two opposite scroll shafts rotating and compressing with involute tooth profile. The refrigeration capacity ranges from 2500 to 4300Kcal / h. In order to improve efficiency, the machining tolerance of the scroll shaft of the scroll compressor is required to be very precise. Due to the recent development of manufacturing technology, high-precision machining can be performed, so the scroll compressor Machines are widely used in air conditioning and low temperature products. In addition, this type of scroll compressor has smaller torque fluctuation than reciprocating type or rotary type, does not need suction valve or discharge valve, and the sliding speed of the compression element is slow. In addition, there are many advantages in pr...
