AI Technical Summary
Technical Problem
The existing fuel injection screw compressors do not optimize the fuel injection angle, resulting in uneven distribution of lubricating oil in the compression chamber, affecting the heat exchange effect of the gas.
Method used
By optimizing the fuel injection angle, the injection direction is deflected from the airflow direction at the outlet of the fuel injection hole, and the combined speed of the fuel injection speed and the airflow speed are increased, thereby improving the diffusion effect of lubricating oil.
Benefits of technology
By optimizing the injection angle, the lubricant oil distribution in the compression chamber is more evenly, extending the diffusion time of the lubricant oil and improving the heat exchange effect between the lubricant oil and gas.

Abstract
The invention discloses a screw compression main machine based on oil injection angle optimization. The screw compression main machine comprises an outer shell, a compression cavity is formed in the outer shell, and a plurality of rotors are arranged in the compression cavity; an oil spraying hole is formed in the outer shell and communicates with the compression cavity; the oil injection speed of the oil injection hole is V1, and the direction of the oil injection speed V1 is the oil injection direction; the airflow velocity at the outlet of the oil spraying hole is V2, and the direction of the airflow velocity V2 is the airflow direction; a certain deflection angle alpha is formed between the oil injection direction and the normal of the shell at the position of the oil injection hole, so that the oil injection direction deflects towards the airflow direction at the outlet of the oil injection hole, and the resultant speed V3 of the oil injection speed V1 and the airflow speed V2 is increased. The oil injection angle is optimized, so that lubricating oil is more uniformly distributed in the compression cavity.
