Spherical roller bearings are popular across industries because they can take very heavy loads and are self-aligning. Their design allows them to take combined loads in both the radial and axial direction acting together.
At the high temperatures and pressures in boilers, well-operated and maintained chemical feed systems are critical for preventing corrosion. However, the task becomes more challenging if corrosion products from other areas of the system travel to and deposit on boiler tubes. The chemistry beneath deposits can be quite different than in the bulk boiler water, sometimes resulting in severe corrosion.Â
As the lights flicker and the machines hum, strange noises echo through the factory floor. Are they signs of restless spirits—or just neglected preventive maintenance? This Halloween, step into the wriggling insides of your equipment and uncover the mechanical mysteries behind every eerie creak, rattle, and groan. Sometimes, the scariest sounds aren’t from ghosts…but from failing components.
A better approach is to measure or deduce shaft RPM and either set unique alarms for different operating conditions or only collect vibration reading if the machine is at the right RPM.Â
Failure analysis of a gearbox, fan, bearing and shaft. When equipment breaks unexpectedly it is good practice to investigate why it happened so that the root cause can be rectified and the problem prevented from again happening.
Don’t run centrifugal pumps on the end of the curve. Pumps are designed and selected to operate near their highest efficiency point. If they operate at the right-hand end of the centrifugal pump curve the likelihood of cavitation increases.
even with consistent high-purity makeup, boiler systems require chemical treatment at strategic locations to further inhibit corrosion and scale formation in the high-temperature environment.  This installment outlines fundamental steam generator treatment concepts and common chemical feed locations for conventional, high-pressure power generation units.
How do control valves work? Control valves regulate the flow of a liquid or gas by opening or closing internal passages. They form part of a control loop used to control a process. The control valves respond to instructions from the controller and adjusts the internal openings accordingly.
