Description

Technical Field

[0002] The present invention belongs to the technical field of bearing fault monitoring, and specifically relates to an intelligent and precise oil injector and an automatic lubrication oil injection management and alarm system. Background Art

[0003] In industrial production, the lubrication management of mechanical equipment (bearings) is directly related to the operation efficiency and service life of the equipment. The traditional manual lubrication method has many limitations: on the one hand, it is difficult to accurately control the oil volume during manual oil injection, which easily leads to insufficient lubrication or over-lubrication. The former will accelerate equipment wear, and the latter will cause waste of lubricating oil and environmental pollution; on the other hand, manual lubrication cannot achieve real-time monitoring and precise control. Especially in high-temperature, high-pressure or dangerous working conditions, manual operation poses safety hazards. In addition, with the improvement of industrial automation level, the traditional lubrication method can no longer meet the intelligent and precise requirements of modern intelligent manufacturing for equipment maintenance. Therefore, it has become an urgent need in the industry to develop a lubrication system with functions of automatic monitoring, intelligent control and precise oil injection.

[0004] Therefore, in view of the above technical problems, it is necessary to provide an intelligent and precise oil injector and an automatic lubrication oil injection management and alarm system.
