Concealed Rust Results In Loop of Failures

When dealing with component failures and continuously high particle count readings on a given hydraulic system, especially systems using water glycol or in a high-moisture environment, make it a point to drain the tank and inspect the underside of the reservoir top. Moisture in the reservoir has the tendency to form rust inside the tank top.

Vibrations during the operation of the system will knock the rust particles into the oil, where they are picked up by the pump and distributed throughout the system. New rust particles form where the old ones fell off and the endless contamination cycle continues. Changing filters and off-line filtration are not solutions to the problem. Replacing the reservoir is sometimes the most cost-effective solution. (Michael Liberty, Liberty Fluid Power Services.)

Constructing a Multigrade Oil

From the "The Practical Handbook of Machinery Lubrication"

Multigrade oils are made by blending a low viscosity oil with special additives called viscosity index improvers. For example, when these polymer additives are blended in the correct proportion with an SAE 15W oil, the oil flows like an SAE 15W oil at low temperatures and like an SAE 40 oil at high temperatures. The result is an SAE 15W/40 oil that will provide wide protection over an extended temperature range.

Implementing Operator-assisted Lubrication
With 43 percent of U.S. companies pursuing a form of lean manufacturing, operators are increasingly being asked to assume some or all of a plants maintenance activities. And while Toyota is living proof that operator involvement can and does work, there are a few simple rules that will help you avoid problems in the future. Learn how to implement operator-assisted lubrication correctly the first time in this learning session at Noria's Reliable Plant 2009.

Compressor Lubrication Best Practices

Nearly all compressors require a form of lubricant to either cool, seal or lubricate internal components. Heinz Bloch discusses what works and what doesn't with compressor lubrication, lubricants, seal oil systems and lubricating oil system operations.
