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.
Asset Management / Life Cycle Cost
When Benjamin Franklin wrote, “An ounce of prevention is worth a pound of cure,” he was referring to fire safety. But, as you may know from experience, this saying holds true with regard to preventive maintenance (PM). Simply stated, preventive maintenance is an activity performed at a set interval to maintain an asset, regardless of its current condition. It’s a properly planned activity, where materials and parts are on hand and labor is scheduled ahead of time.
How often is the phrase “The ROOT Cause of the problem” used at your plant/mill? This phrase is a bit symptomatic of how Root Cause Analysis is thought of. The phrase implies that there is only one “cause” to the problem. Rarely is there a single root cause to any given problem. Usually, there are several reasons; to be sure there are several “technical causes” that interact to create a breakdown/failure.
The need for health monitoring in industrial machines using vibration analysis for diagnosis is an ever growing requirement in all types of industries and equipment. Vibrations in machinery can take various forms, and most of the time these vibrations are unintended and undesirable. Therefore, monitoring the vibration characteristics of a machine can provide the information of its health condition, and this piece of information can be used to detect problems that might be incipient or developing.
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.
Drone-based nondestructive testing allows easier, faster and inexpensive identification of flaws and defects on materials. Using location and other controls, the drones can take the same tests from the same point and angle repeatedly. Drone-based inspection and maintenance provides a wide range of possibilities that take advantage of the mobility of the drone, as well as the nondestructive nature of the tests. These tests can help oil and gas companies identify defects and reduce the rate of failures and unplanned shutdowns. The delicate nature of the oil and gas industry requires close and careful monitoring of its systems, such as pipelines, refineries and more.
I decided to write on this topic because I continually hear people say that oil doesn’t go bad, it just gets dirty. This implies that if you keep the oil clean, it will last forever. This is not true. I am frequently dismayed to see how many people simply don’t change the oil in certain machines. In general, all in-service lubricants will fail at some point.
“I have heard many different opinions as to whether funnels should be used for topping off an oil reservoir. Can you explain why funnels should or should not be used?” Across industry, it seems that if you are filling a machine or topping it off with oil, you will need to transfer the lubricant from a large container through a small fill port at the top of the machine. A funnel is designed to make this opening wider for adding oil. While funnels can make this task easier, they are not recommended because of their potential to introduce contaminants into the lubricant.
