Problems solved by technology

If the three compressors 11, 12, and 13 are high-pressure compressors, when the compressor 11 works and the compressors 12 and 13 are closed, since the compressor 11 is in a high-pressure state, the pressure of the compressor 12 and the compressor 13 is lower than Compressor 11 pressure, so the oil in compressor 11 will continue to flow to compressor 12 and compressor 13, unable to achieve compressor oil balance

Abstract

The invention discloses an oil balance system for a plurality of compressors. The invention comprises at least two parallelly connected compressors, an oil container communicated with oil drain pipes of the compressors, wherein the top of the oil container is communicated with inlet pipes of the compressors; the bottom of the oil container is connected with all inlet pipes of the compressors through oil return pipes. The aim of the invention is to provide an oil balance system for a plurality of compressors, which is used for resolving oil balance problem among the plurality of compressors.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a multi-compressor oil equalization system. Background technique [0002] In a multi-compressor parallel system, in order to prevent the compressor from running out of oil and ensure the reliability of the compressor, it is necessary to balance the oil volume of each compressor. [0003] At present, the oil balance method of compressors is mainly to balance the oil volume among the compressors through the exchange of oil volume between the compressors. However, when there are more than 3 compressors connected in parallel, sometimes it is impossible to guarantee the oil exchange between the compressor with more oil and the compressor with less oil. In this way, the oil quantity balance of each compressor cannot be guaranteed. [0004] see figure 1 As shown, this figure is a schematic diagram of parallel connection of three compressors in the prior art. When the three compr...
