There are two commonly used testing methods to determine a vertical pump’s natural frequency. The first method is called a startup or coast down. In order to perform this method, a tach signal is required for the speed to be tracked. The pump is started and the amplitude and phase are recorded during start-up and […]

Reposted from ReliabilityWeb One method of detecting vacuum leaks is to use airborne ultrasound detection, a technology already widely used for positive ultrasound leak detection in compressed air systems. But finding vacuum leaks is not as straightforward as finding pressure leaks, and oftentimes, the method is abandoned in frustration. One problem here is the quality […]

For rotating machines, it is necessary to reduce friction most of the time to increase efficiency, decrease power losses and support loads. The element of choice is the well known team of bearing and lubricant. Bearings, in their different configurations, are one of the most efficient ways to reduce friction between a stationary and a […]
