Abstract

The invention discloses an involute type air intake multi-grade turbofan comprising an involute type air intake shell, a main rotating shaft, fixed turbines, movable impellers, a middle shell and an air outlet shell. The fixed turbines are fixedly arranged in the middle shell. The movable impellers are fixed to the main rotating shaft and rotate along with the main rotating shaft, and each movableimpeller is located on one side of the corresponding fixed turbine. The involute type air intake shell is arranged at one end of the middle shell, and the air outlet shell is arranged at the other end of the middle shell. The involute type air intake shell is in an involute spiral shape and of a pipe body structure. Air enters the involute type air intake shell in the tangential direction. The involute type air intake multi-grade turbofan solves the problem of splashing of lubricating grease; due to the structure, a better air intake effect is achieved, pressure loss is reduced, and the overall performance of the turbofan is improved.

Description

technical field [0001] The invention relates to a turbo fan, in particular to an involute type air inlet multi-stage turbo fan. Background technique [0002] The pneumatic ship unloader is a machine that uses the negative pressure airflow formed by the fan in the pipeline to suck and unload bulk materials (such as grain, cement, etc.) from the cabin. The requirements for the fan are high efficiency, air volume, and wind pressure to meet the requirements of conveying materials. When the wind pressure changes, the air volume changes little and is easy to maintain. The research and development of high-efficiency, environmental-friendly and low-noise multi-stage turbo blower will enable the company to truly master the core technology of pneumatic ship unloaders. Such as Figure 4 As shown, the traditional multi-stage turbo fan has built-in air inlet bearings, which may easily cause grease to splash on the moving turbine, affect the dynamic balance of the moving impeller, and th...
