Problems solved by technology
However, when the rotary shaft of the compressor is rotating at a high speed, the oil supply may be too high. Excessive lubricating oil will not only cause a waste of lubricating oil but also may lead to a decrease in the efficiency of the heat exchanger, thereby affecting the compressor system. operation and performance
On the other hand, in the case where the rotary shaft of the compressor rotates at a low speed, there is a possibility that the components are overheated and worn due to too little supply of lubricating oil, thereby degrading the performance of the compressor

Embodiment Construction
[0032] The following descriptions of various embodiments of the present disclosure are merely exemplary, and by no means limit the present disclosure and its application or usage. The same reference numerals are used to denote the same components in the respective drawings, and thus the configurations of the same components will not be described repeatedly.
[0033] First, refer to figure 1 Describe the general construction of a scroll compressor. Such as figure 1 As shown, the scroll compressor 1 includes a housing 10 . More specifically, the housing 10 may be composed of a substantially cylindrical body 12 , a top cover 14 disposed at one end of the body 12 , and a bottom cover 16 disposed at the other end of the body 12 . A partition 20 is arranged between the top cover 14 and the body 12, and the partition 20 divides the internal space of the housing 10 into a high-pressure side and a low-pressure side, wherein the space between the partition 20 and the top cover 14 for...

The invention provides a lubricating oil supply device and a rotating machine. The lubricating oil supply device comprises an upper plate, a first angle plate, a second angle plate and a gasket. The first angle plate and the second angle plate extend downwards from the upper plate. The gasket is arranged below the first angle plate and the second angle plate, and a first hole allowing lubricatingoil to flow in is defined by the gasket. The lubricating oil supply device is characterized in that the lubricating oil supply device further comprises a throttling piece, the throttling piece is connected to the upper plate above the upper plate and defines a second hole allowing lubricating oil to flow out, and the throttling piece is configured to limit the flow of the lubricating oil flowing through the second hole. According to the lubricating oil supply device, excessive oil supply can be avoided under the condition that a rotating shaft rotates at a high speed while the lubricating requirement under the condition that the rotating shaft rotates at a low speed is met, and therefore the performance of the rotating machine is improved.
Description
technical field [0001] The present disclosure relates to a lubricating oil supply device and a rotary machine including the lubricating oil supply device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] A compressor generally includes a housing, a compression mechanism accommodated in the housing, a rotary shaft for driving the compression mechanism, and the like. Generally, a compressor requires a lubricant (hereinafter referred to as lubricating oil or oil) to lubricate, seal and cool compressor components (such as bearings, compression mechanisms, etc.). When the compressor is running, the rotary shaft is rotated by the motor to drive the compression mechanism to compress the working fluid, and at the same time, lubricating oil is supplied to various components of the compressor through the lubricating oil supply passage of the rotary shaft. ...
