The present invention is a new ejection structure, most of the models installed and used at present are centralized ejection structures. This type of ejector has the characteristics of simple structure and high strength, but the disadvantage is that the ejection ratio is low and the performance is slightly poor. The technical solution of the present invention is to divide the injection structure into a nozzle ring, a rear sealing ring and a flange joint, and the three parts are all formed by integral machining, and then welded to form the injection body. This structure improves the injection performance, avoids the problem of insufficient strength of the overhanging nozzle, reduces the number of welds, eliminates weak links, and improves its overall reliability.
Description
technical field [0001] The invention relates to an ejecting structure. Background technique [0002] Ejectors are widely used in air circulation refrigeration systems. The ejection performance of the traditional multi-nozzle ejector is acceptable, but due to the problems of structure and processing technology, the failure rate remains high during use and cannot meet the reliability requirements. Ejector replacement. [0003] Most of the models currently installed and used are centralized injection structures. This type of ejector has the characteristics of simple structure and high strength, but the disadvantage is that the ejection ratio is low and the performance is slightly poor. Contents of the invention [0004] The purpose of the present invention is to provide a new type of ejection structure, which can well solve the problem of low performance of the traditional annular ejection structure and centralized ejection structure, and can well compensate for the streng...
