Diagnosing a Low-Speed Gearbox Problem

Any number of impurities can cause scaling and corrosion in boilers unless properly controlled. But even with properly-treated makeup, boilers require internal treatment to minimize corrosion and other problems. The high-temperatures and pressures in boilers magnify chemical reactions and corrosion mechanisms. This installment examines important boiler water treatment concepts.

RCM may have been thought of as a strategy best left to large organizations. That may have been a perfectly logical assumption. Small-to medium-sized enterprises (SMEs) and lean operations simply seem to have less money to invest in and fewer resources to cope with the many activities required for RCM success. Now, however, out of joint academic/industry collaboration in Spain, comes information that may help begin to put these types of popular misconceptions to rest. The RCM methodology described in this overview of the Spanish research has been adapted to meet the specific needs of today’s smaller, leaner organizations. And it is not just a theory, either. The practicality of this approach is being confirmed through actual testing in SME and/or lean companies.

A simple fault-finding technique. Fixing plant and equipment about which you know little is daunting. Here is a simple way to help you successfully find faulty or failed equipment.

Damaged hydraulic cylinder rods and wiper seals are an eternal problem for users of hydraulic machinery. Dents and gouges on the surface of hydraulic cylinder rods reduce seal life and give dust and other contaminants an easy path into the hydraulic system. Many hydraulic cylinders also have bent rods, which cause distortion and ultimately premature failure of the seals.

Often overlooked is the opportunity to invest more in preventive maintenance training, ensuring maintenance team members are well-equipped to recognize potential issues and to fix equipment before it requires a more significant intervention.
