Problems solved by technology

Although it has the advantage of easy operation, the actual effect is very bad. Problems such as the contamination of lubricating oil and the falling off of metal fragments will still occur in actual use, resulting in an increase in the failure rate of the compressor.
Moreover, the general running-in adopts independent running-in of each machine, and does not share equipment with each other, which wastes resources and is inefficient

Abstract

The invention relates to a grinding-in device for new grouped refrigerating compressors, and belongs to the technical field of refrigerating compressors. Working media flow from a compressor via a high-voltage side heat exchanger (4) and are cooled, pass through an air throttle valve (5), the pressure is lowered; and the working media flow via a low-voltage side heat exchanger (6), and return to the compressor (1) after heat is further absorbed. A reservoir (9) is connected at an outlet of the low-voltage side heat exchanger (6) and refrigerating fluid is replenished or recycled according to system requirements; the high-voltage side heat exchanger (4) and the low-voltage side heat exchanger (6) can be air-cooled or water-cooled; and a single or a plurality of new compressor are connected with an air distribution bag (7) and an air-collecting bag (3) through hose speedy interfaces (2). The grinding-in device has the advantages that production efficiency of a grinding-in process of the new compressors on load is improved; system circulation working media can be nitrogen or refrigerating fluid; enclosed-type grinding-in facilitates cleanness; new compressors are connected rapidly and conveniently by the aid of the air distribution bag, the air-collecting bag and the hose speedy interface, utilization rate of the system is increased; and the heat exchanger can be both water-cooled or air-cooled flexibly.

Description

technical field [0001] The invention relates to a device for running-in a new group of refrigeration compressors, which belongs to the technical field of refrigeration compressors. Background technique [0002] After the current refrigeration compressor is produced, it generally adopts an open cold break-in without load, and the start-up time is about 24 hours. Although it has the advantage of easy operation, the actual effect is very bad. Problems such as the contamination of lubricating oil and the falling off of metal fragments will still occur in actual use, resulting in an increase in the failure rate of the compressor. Moreover, the general running-in adopts independent running-in of each machine, and does not share equipment with each other, which wastes resources and is inefficient. Contents of the invention [0003] The present invention designs a device for breaking-in of new refrigeration compressors in groups, aiming at improving the production efficiency of n...
