Just like everything else, lubricants have a shelf-life. If you treat them right, this can be anywhere between six months to three years depending on the type. However, lubricants will only reach their max life expectancy if they are stored and cared for properly.
Like blood coursing through the veins of living beings, lubrication is what keeps a plant’s capital investments operating smoothly and efficiently. At the same time, when lubrication becomes contaminated or depleted of its sustaining properties, overheating or exhaustion are among the problems that can occur. That leads to downtime and loss of production, and the potential of some hefty maintenance expenses.
Using in-service oil analysis to improve machinery reliability has a long history. The first oil analysis was performed over half a century ago on a locomotive engine. Just as a human blood test provides important information about your health, the information provided by in-service oil analysis about machinery health, especially for a piece of complex machinery with many moving parts, such as a diesel engine, is unmatched by any other technologies on the market.
The result of their failure can be unexpected downtime, higher maintenance costs or even personnel safety risks. In the worst cases, human lives may be at stake. It is time to stop treating grease as some simple substance that just needs to be pumped into machines at some random frequency and then hoping for the best. Machine greasing must be a systematic and carefully planned process to ensure safe operation of assets and to achieve maximum equipment life.
One of the best ways to achieve fault-free operation of paper machines is to ensure the proper lubricant is applied to the frictional surfaces. Most paper machines have hundreds, if not thousands, of lube points that require periodic application of oil or grease. There are bearings, gears, couplings, journals, cylinders and valves which must all receive the correct lubricant to survive the rigors of the paper-making process.
Machinery and Equipment MRO interviewed three oil and lubrication specialists to uncover industry trends that are important to suppliers and users alike. They were asked to consider factors that significantly influence decision-making on more easily protecting equipment, and to share insights on what’s new, what holds value and provides improvements, as well as what helps solve common problems.
High-pressure injection injuries, also known as grease gun injuries, are caused by the accidental injection of a foreign material–such as grease, oil, or solvent under pressure–through the skin and into the underlying tissue. This is analogous to medical techniques used to administer immunization shots without a needle. A grease gun injury can cause serious delayed soft tissue damage and should be treated as a surgical emergency. Any person sustaining an injury of this sort should seek immediate medical attention, regardless of the appearance of the wound or its size. Accidents involving injection injuries can occur when using any type of pressurized equipment.
Unfortunately, there is not an easy way to tell if lubricants have been mixed unless they have vastly different viscosities, such as ISO 32 and ISO 680. The best solution would be to avoid this problem in the first place by having trained staff members and well-labeled/color-coded equipment. Using a different sealable and reusable container for each lubricant can help to prevent cross-contamination.
