Comperssor nozzle

Abstract

The invention discloses a kind of compressor spray nozzle. The trait of the invention is: the foundation of the compressor spray nozzle is screw. There is spiral groove or bevel grooev on the round outside. Exit of the spiral groove or the bevel groove connects both upper and bellow ends of spray nozzle. After the spiral groove or the bevel groove is done in the outside of screw, parts of the threads are resected but the left threads can also fix the spray nozzle into the columnar cavity of the compressor body. Certainly, spray nozzle can also be fixed in the columnar cavity of the compressor body by pass-filled coordination. The columnar cavity of the compressor body is usually produced from the compressor body, is one part of the body and they are the whole body. The columnar cavity can be made into a single part and then be fixed on the compressor body. One end of the columnar cavity is conical throttle hole, whose exit is communicated with the working air cavity compressor. The invention is applied for compressors with any exhausting capacity, and result of atomizing is good.

Description

technical field [0001] The invention relates to a nozzle for compressor cooling. Background technique [0002] At present, when the compressor is working normally, liquid is usually sprayed into its working cavity, the main purpose of which is to reduce the temperature of the compressor and the compressed gas, and at the same time have the functions of lubrication and sealing. The liquid injected into gas compressors is usually oil, while oil-free compressors are injected with water, and refrigeration compressors are injected with a mixture of oil and liquid refrigerant. The amount of liquid spray should be appropriate, neither too large nor too small. Now only take the exhaust temperature of the oil-injected air compressor as an example to illustrate. The amount of oil injected is related to the exhaust temperature of the air compressor: when the amount of oil injected is too small, the exhaust temperature will be too high, which will affect the life of oil, bearings and ...

AI Technical Summary

Problems solved by technology

However, since the atomization effect of this nozzle 1 is poor when the aperture is large, in a compressor with a large displacement, multiple nozzles 1 have to be designed in different parts of the compressor. In some compressors, multiple nozzles are arranged. It is difficult to install a single spray point, and the piping system is relatively complicated, resulting in the disadvantages of increased cost, large space occupation and low production efficiency.
