A couple of weeks ago we calculated cold alignment targets from field data. We ended up with angles and offsets but the class wanted to go through the math involved in calculating the foot values. It was an interesting math exercise so if you’re up for some brain stretching, follow along. Here are our target…
Read MoreA recent training class offered us an opportunity to check both the hot and cold alignment conditions on a blower. It was a great time to calculate our own thermal offset values from field data and compare them to the OEM recommendation. So how do we go about doing this? Why would we even want…
Read MoreIt’s a new year and time to reassess our goals. We test our gauges, adjust sensor settings, tweak valves, etc. We check our equipment against a standard to verify it still works optimally. When’s the last time you have done the same for your mechanics and technicians? VibrAlign’s shaft alignment courses will calibrate your personnel to…
Read MoreJacking bolts provide a smoother, easier way of moving machinery than using pry bars and hammers. Their use will almost always speed up the alignment process, prevent excessive minor moves back and forth, and generally make the task of shaft alignment much more pleasant. More and more companies are realizing the benefits of using jacking bolts…
Read MoreAny equipment that goes through large temperature differences between startup and normal operation should have accurate thermal targets calculated to allow for proper shaft alignment. Shaft alignment data can be taken when the machine is at operating temperature and compared to readings taken when the machine is at ambient temperature. The resulting calculations provide alignment…
Read MoreBowl mills are used to pulverize coal prior to being blown into coal fired boilers. They are very large machines with heavy rotating components usually driven by an internal planetary gear set in the bottom of the mill. A typical steam generation power plant will have multiple bowl mills for each boiler in the facility.…
