Description

Technical Field

[0001] The utility model belongs to the technical field of air compressors, and in particular relates to an axial force balancing device for air compressors. Background Art

[0002] Air compressor, also known as air compressor, is a machine that compresses air to increase gas pressure or transport gas. Air compressors are available in three types: piston, centrifugal and screw. They are mainly used to drive various pneumatic tools, brake and control fields; in the food and pharmaceutical industries, air compressors are mainly used to compress air to stir slurry. The control of air compressor noise mainly adopts three aspects: muffler, muffler tunnel and sound insulation technology.

[0003] The rotor of a centrifugal compressor rotates in the gas inside the machine body. Both sides of the impeller are affected by the gas pressure. The directions of the gas forces are opposite, and they can balance each other partially. The sum of all the impeller axial forces is the axial thrust of the entire rotor. The direction of the axial force is generally from the high end to the low pressure end. After the axial thrust of the rotor is balanced, the remaining axial thrust is balanced by the thrust bearing. If the thrust is too large, it will affect the life of the bearing, and in severe cases, it will damage the bearing, cause the rotor to move, and cause the parts and fixed elements on the rotor to collide, and even damage the machine. Therefore, during operation, attention must be paid to the changes in the axial force to ensure the safe and stable operation of the compressor. Utility Model Content
