Diagnosing a Low-Speed Gearbox Problem

Even with consistent Preventive Maintenance for wintertime heating, any heating device can eventually take on wear and tear that requires repair or replacement. Industrial maintenance teams can stay ahead of it by remaining vigilant for common warning signs, allowing them to intervene before their building faces a major disruption. 

The focus of the previous installment was on cooling water microbiological fouling and control basics, as fouling can cause the most prompt and intense damage in cooling systems.  However, scaling and corrosion can be problematic as well.  Because scale and corrosion control programs often overlap, the next two installments will outline, respectively, primary scale-forming and corrosion mechanisms (scale formation in cooling water systems).  We will tie these together in Part 5 when examining the evolution of scale/corrosion control programs.  

A DC Motor carbon brush is an electrical contact which makes a connection with a moving surface. Optimal performance on motors, generators and other types of moving contact applications will be attained only when the carbon brush, the brushholder and the contact surface are properly designed and maintained. All three components are critical factors in a complex electro-mechanical system.

In the next two installments, we will examine the damage caused by oxygen corrosion in boiler feedwater and condensate return systems during operating and layup periods.  A major focus is on carbon steel corrosion and control methods.
