Description

Air compressor machine vibration detection protection system

Technical Field

The utility model relates to a vibration detection technical field more exactly relates to an air compressor machine vibration detection protection system.

Background

The air compressor drives the screw head to rotate through the main motor to compress air to work, and a bearing is inevitably arranged on a rotating part. Vibrations occur when the bearings wear or because the unit is placed unevenly. However, the damage of vibration can be attributed to the following points: 1. the vibration of the motor consumes energy to a certain extent, and further reduces the efficiency of the motor; 2. the vibration can directly damage the bearing of the equipment, so that the abrasion of the bearing is accelerated, and the normal service life of the bearing is greatly shortened; 3. the vibration can reduce the insulation resistance to a certain extent, which is mainly because the vibration of the motor can lead the binding wires at the end part of the motor to be loosened, so that the end windings are mutually rubbed; 4. vibration can cause some parts to loosen, so that other mechanical equipment cannot normally run; 5. the vibration can cause metal fatigue acceleration, and can cause fracture, collapse endangers equipment and life safety. The existing air compressor has no vibration detection protection, and has many defects and potential safety hazards.
