Description

Technical Field

[0001] The invention belongs to the technical field of fan oil leakage management, and in particular relates to a yaw oil leakage management system for a fan unit. Background Art

[0002] At present, there is a common problem of oil leakage in the yaw bearing of the fan unit. The grease that falls on the yaw platform of the fan unit not only affects the hygiene of the fan, but more importantly, it poses a safety hazard. If the fan worker steps on the grease, he may slip and fall, causing problems such as falls. The following are the reasons for the yaw oil leakage: 1. The original yaw adopted an automatic lubrication system, but the current automatic lubrication system has many shortcomings: (1) The lubrication cycle and grease amount are not scientifically set, resulting in over-lubrication or insufficient lubrication; (2) The equipment oil volume lacks closed-loop control, resulting in unsatisfactory results during actual operation; 2. The yaw gear ring is not manually oiled evenly, and the grease squeezed during yaw will fall from the yaw process hole onto the yaw platform of the fan unit; 3. Pipeline blockage occurs frequently. Summary of the invention
