When funds get tight for many colleges and universities, one of the early cuts is often to the facilities department. After all, financial aid and faculty salaries are necessary to be competitive in the market, but updating a building’s boiler or switching to all new lightbulbs is often seen as a luxury that can wait another year.
In the June/July 2016 Uptime article, “Condition Monitoring and MEMS Accelerometers: What You Need to Know,” several attributes of microelectromechanical system (MEMS) accelerometers were presented that make the technology compelling for condition monitoring applications. This article reviews data demonstrating the state of MEMS technology development and performance levels by comparing it to a commercially available piezoelectric (PZT) condition monitoring accelerometer.
With all the technology out there, all talking to each other, the world is increasingly becoming more and more connected – indeed, flat. The Industrial Internet of Things (IIoT) seems like a nebulous concept that encompasses everything from machine learning and robotics to drone delivery systems and intelligent point-of-use vending. There is more information available than ever before, but making sense of all this data can be daunting. This article will help bring clarity to how the IIoT can enhance all aspects of manufacturing.
Interpreting the vibration signature of plant equipment.
Vibration analysis, properly done, allows the user to evaluate the condition of equipment and avoid failures. Maintenance personnel can minimize unplanned downtime by scheduling needed repairs during normal maintenance shutdowns. How can you interpret — at a glance — the comprehensive spectrum information available? In layman’s terms, here is how to interpret the vibration signature of rotating equipment. You can learn to recognize misalignment, a defective bearing, bent or loose parts — and tell them apart.
Several tests can be performed on a hydraulic pump to indicate its condition. The temperature of the pump case, the flow of the case drain and the current draw of the drive motor are common checks that can be done regularly and over a period of time to track the wear of a hydraulic pump.

Do not dismiss the above statement thinking it does not apply to your situation because you are not a roving consultant or contractor. In-house maintenance reliability professionals need to exhibit the same, or even better, customer service when it comes to driving change or pulling their organization toward a path of continuous improvement.
Plain and simple: there’s a lot that goes into a preventative maintenance program for hydraulic systems. While it’s a discipline that’s very basic and uncomplicated when you boil it down, there are many tests that need to be performed and plenty of steps where something can be done incorrectly, so it’s critical to the health of your machine that all are done regularly and properly. In order to do this, it’s important that both the system and hydraulic fluid are taken care of, as your fluid and systems are completely interdependent.
While data quality may seem both simple and obvious, many companies overlook this area due to a misunderstanding on how the CMMS and data are used. In some cases, companies are well aware of their data quality issues, yet don’t understand the affects that poor data can have on their organization. In other cases, companies believe that an expensive new CMMS will be the answer to all of their problems, only to realize six months down the road that they cannot conduct basic part searches and transactional reports.

So, the root cost problem elimination. It’s really just a structured approach to eliminate problems…that’s all it is. It’s what usually happens when people say they do root cause, in my experience, this is the morning meeting and someone says motor tripped-out costing production loss. So, what happens in the morning meeting, now I haven’t been to yours, but somewhere, the first thing people say is this a maintenance problem or is this an operations problem. Oh, it’s a motor that tripped out so this is obviously a maintenance problem. So operations guys they say oh they just lean back and they stop thinking now. So great, we don’t have to worry about this is not our problem. So you lose 75 percent of your thinking power. So the Maintenance Department continues to say “Okay, is this a maintenance problem?” Is it a mechanical problem or is it an E/I problem. And they’re going to say no it’s not mechanical is a motor that trip. Of course that very homogeneous group of E/I we need to figure out is an electrical or instrumentation problem…
Gear pumps are the most common type of positive displacement pump, ideal for transferring high viscosity fluids such as automotive oils, plastics, paint, adhesives, and soaps. They operate by creating suction at the inlet with a rotating assembly of two gears –a drive gear and an idler. Pump flow is determined by the size of the cavity (volume) between gear teeth, the amount of slippage (reverse flow), and the speed of rotation (rpm) of the gears.
