Autol's Automatic Bearing Grease Change Technology of Lubrication
30 Sep 05,2017 Industry News
How many failures to greased bearings are resulted from bad lubrication? The statistics show that, 20% failures are arising from aged lubricant, 15% from insufficient lubrication, 20% from improper lubricant. Additionally, 20% failures are due to solid contaminant and 5% to liquid contaminant. Therefore, the failure to greased bearing are mainly because of lubricant.
On the 2nd International Summit Forum of Machinery Lubrication and Equipment Health Management, Zhao Daping, the Chairman of the Board of Directors of Zhengzhou Autol Technology Co., Ltd. presented in detail our automatic bearing grease change technology. He said that the grease would be of saponification, deterioration, hardening, causing new grease failing to be filled freely, resulting in adverse influence on lubrication effect, if the waste grease cannot be discharged in time. Bad bearing lubrication will cause many adverse consequences. As a worse case, the temperature rise will be significant, with bearing damaged, resulting in major accident even fire. Then, how can the waste grease be removed and replaced?
For the operating principle of automatic grease change technology, the equipment's waste grease collection system is used with centralized lubrication system, which will periodically and cyclically operate for several minutes for some times. The waste grease collection system sucks waste grease from the bearing approximately equaled to the new grease filled into the bearing by the centralized lubrication system.
Autol's centralized lubrication system includes single-line, double-line, progressive and multi-line centralized lubrication systems. And, the single-line centralized lubrication system is designed with in-parallel structure, featuring advantages such as easy expansion, not clogged, convenient maintenance, low costs of maintenance, etc. Long-distance transmission may be realized with boosting pressure technology, with high reliability. Incorporated with progressive distributor, it may form a mixing lubrication system.
Therefore, the waste grease with wear particles may be removed from the bearing inner chamber with automatic grease change technology, reducing bearing friction, good to bearing heat dissipation, eliminating pressure of bearing inner chamber, and ensuring bearing successfully filled with new grease. Used with centralized lubrication system, the bearing inner chamber can always be kept with proper amount of grease, very good to grease film forming and holding. As a result, the bearing life will be significantly prolonged. It is of great significance to continuously operating large bearings.
