What is a typical pump efficiency? Many medium and larger centrifugal pumps offer efficiencies of 75 to 93 percent and even the smaller ones usually fall into the 50 to 70 percent range. Large AC motors, on the other hand, approach an efficiency of 97 percent, and any motor—ten horsepower and above—can be designed to […]
What happens when a clutch pedal is depressed?
What happens when a clutch pedal is depressed? When the clutch pedal is depressed, the cable pulls the clutch fork, causing the release bearing to move forward against the pressure plate. Since the fluid is under pressure, it causes the piston of the slave cylinder to move its pushrod against the release fork and bearing, […]
What are the main types of pumps?
What are the main types of pumps? Pumps can be classified by their method of displacement into positive-displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps and valveless pumps. There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps. Which type of pump is most efficient? Positive displacement pumps are able to […]

How do you start a predictive maintenance program? To recap, the steps to starting a predictive maintenance program at your facility are: Start small. Identify PdM ready assets. […]
Which is used to check the condition of bearing?
Which is used to check the condition of bearing? Utilizing a portable temperature-measuring tool, like a thermal imaging gun, will help you accurately monitor bearing temperature. As a bearing fails, its temperature will continually increase. Trending temperature over time will help identify a bearing in the early stages of failure. How do you check wheel […]
