Topics of this game:
- One of the main causes of premature bearing failure is improper lubrication. Improper lubrication includes inadequate lubrication, excessive lubrication, and ...
- Bearings are selected for applications based on the type of loads that are anticipated. When the load or force acts perpendicularly on the shaft, the force is considered...
- Frequent failures in equipment can point to an underlying issue with the equipment or application. The process of determining the main contributing factor to decreased reliability is referred to as what?
- Forces in rotating machines can be reduced by balancing the rotating assembly. One balancing standard is the ISO standards for residual mass imbalance. In these standards the standard number (G1.0, G2.5, Etc.) specifies the permissible amount of mass imbalance. In this specification is the higher or lower number a more stringent standard.
- The process of installing a rotating machine plays a large part in the equipment's long term reliability. For direct coupled machinery, this would include which of the following?
- One reliability graph that shows equipment failures vs. time (The Bathtub Curve) shows a large number of failures immediately following installation, decreasing failures throughout normal service life, and another increase in failures towards the end of equipment lifecycles. The failures that occur shortly after commissioning are referred to as what?
- Variable frequency drives are used to control electric motors in numerous applications to improve process control and energy efficiency. VFDs, unfortunately, create harmful rotor currents that can damage anti-friction bearings. This damage is referred to as what?
- There are several approaches to maintenance programs. Which of the following is NOT one of them.
- A preventive maintenance program performs maintenance tasks based on a timetable recommended by the equipment manufacturer and personal experience of the maintenance staff. While this is an improvement over breakdown maintenance, what is one possible negative outcome?
- In a predictive maintenance program multiple testing technologies are utilized to ascertain the condition of the equipment. This continuous monitoring helps ensure maintenance evolutions can be well planned and initiated in an efficient time frame. Which of the following is not a type of technology used to monitor equipment condition?
