Bearing lubricating system of coal mill

Abstract

The invention relates to a bearing lubricating system of a coal mill. The bearing lubricating system aims to solve the problems that in the prior art, when a bearing lubricating system of a coal mill works, the running time of an oil pump is too long, machine abrasion is serious, the oil quantity is frequently adjusted, much oil or less oil or oil breaking occurs, the phenomena of burning a bearing, damaging equipment and influencing environment and safety production occur, due to the fact that field noise is high, much dust exists and the environment is poor, the mind and body of work staff on the work field all the time are hurt, and work efficiency is low. The lubricating system comprises a sponge body, a high-position oil tank, an oil pump, a limit contact device, a floater, a shaft, a low-position oil tank, a first oil inlet pipe, a second oil inlet pipe, a first oil outlet pipe, a second oil outlet pipe, an oil return pipe, a spiral adjusting rod, a press plate, two bearing seats with bearings, two liquid level meters and two liquid level control boxes. The bearing lubricating system is used for bearing lubricating systems of coal mills.

Description

technical field [0001] The invention relates to a coal mill bearing lubricating system. Background technique [0002] The existing coal mill bearing lubrication system is mechanical lubrication. The operation is to start the gear oil pump first, and then adjust the oil supply and cooling water of the front bearing of the coal mill, the oil supply and cooling water of the rear bearing, and the oil supply of the gear reducer. and cooling water, start the coal mill after all adjustments are completed. For mechanical lubrication, the amount of oil is not only difficult to adjust, the adjustment is uneven, and the amount of oil often changes. Such frequent adjustment operations make it impossible for the on-duty personnel to leave the milling site. The site is noisy and dusty and the environment is poor, which seriously affects the physical and mental health of employees. Increased the labor intensity of the staff on duty. Bearings are one of the vulnerable parts, and mechanica...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the problem that the coal mill bearing lubrication system in the prior art works due to the long running time of the oil pump, which leads to large mechanical wear, and the frequent adjustment of the oil volume, often resulting in excessive oil, low oil, or oil cut-off, resulting in burning and damage to the bearing. The phenomenon of equipment affecting the environment and affecting production safety, due to the large noise and dusty environment on the site, has brought physical and mental damage to the staff who have been working on the site, and the problem of low work efficiency, and then provides a coal mill bearing lubrication system
