Oil homogenizing structure for scroll compressor

Abstract

The invention discloses an oil homogenizing structure for a scroll compressor, which comprises a closed container of the compressor, wherein the inside of the closed container is provided with a section of oil homogenizing pipe inserted; a position where the section of the oil homogenizing pipe is connected with the side wall of the closed container is provided with a connecting port of the oil homogenizing pipe; the outer wall of the section of the oil homogenizing pipe is sleeved with a floating wall capable of freely moving up and down; the floating ball is positioned between the connectingport of the oil homogenizing pipe and a lower frame fixed to the lower end in the closed container; the outside of the compressor is provided with a floating ball sensor capable of detecting the height of the floating ball at a specific position in the closed container; and the floating ball sensor controls the rotation of the scroll compressor according to the detected height of the floating ball at the specific position in the closed container. On the premise of ensuring excellent oil homogenizing, the oil homogenizing structure effectively reduces the start-stop frequency of the prior scroll compressor, prevents the scroll compressor from being started and stopped frequently and improves the service life of the scroll compressor greatly.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an oil equalizing structure of a scroll compressor. Background technique [0002] Existing scroll compressors used as compressors for air conditioners and refrigerators such as figure 1 As shown, a brief description of its structure is given below. [0003] As shown in the drawing, an upper cover 1b is provided at the upper end of a cylindrical casing 1a of the airtight container 1, and a base plate 1c is provided at the lower end. An upper frame (frame) 2 is fixed to the upper end inside the container, and a lower frame 3 is fixed to the lower end. [0004] In addition, an electric structural component 6 is provided between the upper frame 2 and the lower frame 3, and the electric structural component 6 is composed of a stator 4 and a rotor 5, wherein the rotor is mounted inside the stator 4 and can rotate. A balance weight (Balance Weight, BW) is arranged above and below...

AI Technical Summary

Problems solved by technology

[0016] Currently in order to achieve oil equalization, see figure 2 , a method to achieve oil equalization is: drive and run two compressors A and B at the same time for 2 hours, then stop compressor A for 1 minute, then stop compressor B for 1 minute, and then continue to run the two compressors A and B are repeated for 2 hours, and the logic compulsorily controls the two compressors to perform oil equalization, so that the oil of the two compressors can be evenly distributed. The compressor needs to be stopped, and the compressor starts and stops frequently, which seriously affects the service life of the compressor
