Description

Technical Field

[0001] This utility model relates to the field of motor bearing oil injection technology, and in particular to an automatic oil injection device for explosion-proof motor bearings. Background Technology

[0002] Explosion-proof motors are core power equipment in flammable and explosive environments such as petroleum, chemical, coal, pharmaceutical, and coating industries. As critical rotating components, the bearings of these motors require continuous and reliable lubrication to ensure long-term stable operation and prevent safety accidents caused by overheating due to friction. Currently, the industry primarily relies on the traditional method of manually adding lubricating oil to the filler holes periodically for lubrication of explosion-proof motor bearings.

[0003] Manual lubrication has several drawbacks. In flammable and explosive environments, operators need to frequently approach operating motors to lubricate them. This process may generate sparks from tool collisions, posing a potential ignition source and seriously threatening production safety. Furthermore, manual lubrication requires dedicated personnel for regular inspections and operations, which is particularly problematic in large factories where there are numerous and widely distributed motors, resulting in a large workload and high labor costs.

This makes the oil filling cycle more intelligent and accurate, and the oil filling work safer, more convenient and reliable. It also reduces the cost of manual maintenance and avoids improper operation that may occur during manual oil filling. Attached Figure Description
