Read MoreA vibration analyst’s day is always unpredictable, but there is a general flow that most of us experience. This blog post shares what a typical day looked like for me…
Read MoreBasic machine setups are typically made to collect all the data we need for each asset. This is not always possible or reasonable as we would spend far more time…
Read MoreSampling frequency can be a confusing component of building a time waveform. What makes it confusing for many analysts who are learning Level III concepts is that it is always…
Read MoreThere are times when you will observe sidebands in the Fast Fourier Transform (FFT) spectrum. These sidebands are a common occurrence and are often linked to specific mechanical and electrical…
Read MoreFrequency is as simple as the name implies, it is the number of times an event occurs in a set amount of time. In vibration analysis, we reference frequency to…
Read MoreAll successful reliability programs have one thing in common – strong communication between all plant resources. Although this concept does not have any direct relevance to maintenance, it is an…
Read MoreThere are times when it is useful to take 2 simultaneous measurements and compare the phase (or position of the shaft) from one position relative to the other. This is…
Read MoreGearboxes are used in numerous applications, including machine tools, industrial equipment, conveyor belt drives, and just about any power transmission application with rotary motion that requires a change in torque…
Read MoreThe Journey of Reliability A machine is identified by the vibration analyst and recommendations are made for repair, the planner orders the parts, management gets together and determines when the…
Read MoreCentrifugal pumps are common in industry. They are used to move various liquids from one place to another. This work is performed using a rotating pump wheel, or “impeller”, with…
Read MoreResonance, critical speed, and natural frequency are all very similar terms and refer to the same phenomenon. An increase in equipment vibration, not relating directly to a specific component, is…
Read MoreIt is important in vibration analysis to know whether the vibration data you are looking at is actually “good data”. Below is a review of the causes and symptoms of…
Read MoreFans are a very common component in industry, they are used to move air from one place to another. Fans are used in dust collection, supplying air to boilers, provide…
Read MoreIt’s on all of the vibration fault charts, it’s taught in vibration classes, and it’s used for balancing – but how often is phase actually used by vibration analysts to…
