Abstract
Description
technical field
[0001] The invention relates to the technical field of monitoring, and more specifically relates to a forced lubrication indication and alarm device for a scraper conveyor reducer on a coal mining face. Background technique
[0002] The high-speed shaft bearing of the scraper conveyor reducer in the coal mine fully mechanized mining face generally uses a lubricating pump to absorb lubricating oil from the oil pool, and the lubricating oil enters the bearing through the oil pipe and the oil passage inside the reducer to perform forced lubrication on the bearing. Due to the damage of the lubricating pump, the blockage of the oil pipe or oil passage, etc., the high-speed shaft bearing of the reducer is short of oil, which can cause the bearing to fall apart and lock, affecting the normal production of the working face, resulting in waste of manpower and material resources and large economic losses.
[0003] Therefore, it is necessary to design a device that can ...
