Control of equipment lubrication oil consumption loss
Thread Content
Help: Are there any standards or specifications regarding the lubricant consumption of rotating equipment? For example, how often and how much lubricant is required for a centrifugal pump under normal conditions.
There is no issue of varying levels of loss for lubricating oil; it depends on the specific equipment and operating conditions
So how is the total amount of lubricant in the workshop controlled?
For different devices, the amount and type of lubricating oil or grease required vary. The service life of lubricating oil also differs under different operating conditions. Each pump manufacturer provides guidelines regarding the amount of these consumables needed and the frequency at which they should be replaced; it seems that there are no specific standards for this.
The diesel engines we purchase from Valmet in Finland specify that, in terms of technical specifications, the lubricant consumption per kilowatt-hour is no more than 0.5 mg, based on the output shaft power. Of course, this applies to heat engines, as for them, the consumption of lubricating oil is part of the daily operating costs of the unit. For ordinary mechanical pumps, the consumption of lubricating oil is influenced by many factors, such as the quality of the lubricating oil, its compatibility with the equipment, the age of the equipment, and the comparison between the designed operating conditions and the actual operating conditions. It is very difficult to measure it with a specific indicator.
There are no specific standards regarding the lubricant consumption of rotating equipment; generally, centrifugal pumps require their lubricant to be replaced every 3 months to maintain their inherent lubricating properties. Sampling analysis can be conducted; if the parameters are within acceptable limits, it can continue to be used, while replacement is advisable if they are not.
Then it’s impossible to determine whether there is any waste in the amount of lubricant used in the workshop, right? How can it be regulated and restricted?
What to do about waste in the workshop? How can one determine whether there is waste?
There is no specific standard for the amount of lubricant to use； If there is a leak, the amount used will definitely be high ； If there is no leakage, it mainly depends on the oil cup ； Just add oil according to the oil level in the oil cup ；
Again, ask the manufacturer about the normal consumption rate and replacement cycle, and then keep some extra stock based on the actual circumstances.
The cost of lubricant is covered by the workshop; oil is not changed casually unless it is necessary. Replacing the lubricant when the test shows it is qualified is a waste.
