KZB-PC Motor Main Bearing Temperature and Vibration Monitoring Device

Air compressors are now widely used in coal mines and non-coal mines. As the main component of air source equipment, an air compressor converts the mechanical energy of a prime mover (usually an electric motor) into the pressure energy of gas, serving as a compressed air pressure generating device that bears critical responsibilities for safe production in mining systems.

The motor, being the core component of an air compressor, is highly important both in terms of operation and cost. Motors are prone to two major issues:

1. Bearing failure: Comprehensive vibration analysis and information reflected by various bearing components indicate that the bearing cage is not a load-bearing part during equipment operation. When operating conditions change or frequent loading and unloading occur, additional loads are imposed on bearing components, worsening the bearing's stress conditions. This causes defects in the bearing cage to gradually expand under repeated additional loads, leading to fractures in locally defective cage supports. As a result, some rollers squeeze against each other, generating a large amount of heat in a short time, causing a sharp rise in bearing temperature. The thermal expansion and reduced hardness of bearing components ultimately lead to bearing failure.

2. Motor temperature rise:

During motor operation, the allowable temperature of the bearing outer ring should not exceed 95°C. Exceeding this value indicates excessively high motor bearing temperature, also referred to as motor bearing overheating. Bearing overheating is one of the common motor faults. In mild cases, it causes lubricating grease to thin and leak; in severe cases, it damages the bearing, not only causing economic losses to users but also rendering the air compressor inoperable, potentially leading to irreversible accidents.
