Lubrication is the most important PM work for rotating equipment. To ensure that lubrication is done correctly it is very important to have a dedicated database of all equipment needing lubrication comprising part to be lubricated, lubricant recommended by OEMs, interval for makeup & replacement etc and issue periodical lubrication schedule for implementation. It is very important to assign skilled technician for lubrication work. Also important is to monitor the lube oil level of the major equipment during daily walk down. It is also a good practice to check the viscosity of oil at regular intervals for major equipment.
It is very important to know that you are using the right lubricant for the application you are lubricating. Lubricants are designed to work in different environments and the operating temperature of the equipment that you are lubricating must be evaluated. Check what the temperature range the lubricant is able to work in and its viscosity are all so important.
To avoid failure of lubrication you need to:
Keep it clean
Keep it dry
Keep it cool
The critical matter in lubrication is control the analyzing lubricant properties and suspended contaminants for the purpose of monitoring and reporting timely, meaningful and accurate information on lubricant and machine condition. An antioxidant is an example of an additive that will be expended over its useful life until it becomes empty without warning. Without antioxidants, oxidation byproducts are allowed to corrode equipment parts, thickening the oil and reducing the base oil’s lubricating properties. The rate of lubricant failure, and consequently machine failure, increases rapidly.
As well as Contamination rates can also be a silent danger. The problem arises when too many contaminants are allowed to exist in the workings of a machine. These contaminants can generate more contaminants through three-body abrasion.
