Oil lubrication is a commonly used lubrication method for operating equipment in industrial production at present. The lubricating oil is generally added in a bearing oil tank of running equipment and has the following functions: when the bearing runs, the lubricating oil plays a role in lubricating and cooling the bearing, so that the bearing and a bearing bush are prevented from being abraded due to friction heating, and the key point for playing the lubricating role is that the lubricating oil forms a layer of oil film on the friction surface of the bearing; the current lubricating method adopted by the motor bearing of the reciprocating compressor is annular oil throwing type lubrication, and the annular material is Cu. The lubricating method has the defects of uneven lubrication, difficulty in controlling the amount of lubricating oil and poor lubricating effect, and the condition of compressor interlocking jump and even bearing wear is often caused by high temperature of a motor bearing; in addition, the motor bearing bush is inconvenient to maintain after being worn, and the maintenance cost is high, so that the problem is particularly important to solve.
