Temperature Shock of Hydraulic Components and How to Avoid it

When there is a significant difference between the temperature of a hydraulic component and the fluid being supplied to it, rapid, localized heating of the internal parts of the component can occur. This causes individual parts of the component to expand at different rates, resulting in interference between parts that normally have fine clearances.

Steam Maintenance: Inspect Steam Traps for Efficient System

Unfortunately, when it comes to steam traps, people often ignore them. There’s a complacency about them that is costing steam users much more than they realize. The hard reality of a plant maintaining its boiler and forgetting about the rest of the steam system can be a horribly wasteful proposition. Losses can include not only wasted energy but replacement of damaged equipment and misuse of man-hours. It is not uncommon to discover system losses in the hundreds of thousands of dollars.

Hydraulic Pump Life Cut Short by Particle Contamination

Contaminants of hydraulic fluid include solid particles, air, water or any other matter that impairs the function of the fluid. Particle contamination accelerates the wear of hydraulic components. The rate at which damage occurs is dependent on the internal clearance of the components within the system, the size, the quantity of particles present in the fluid, and the system pressure.

Double the Drive Life at One-Third of the Cost

Many drive systems go to an early grave after only about 10 years of operation. Reconditioning an existing drive system could enable it to operate reliably for another decade and can be achieved for just 30-40% of the cost of a new drive system. Peter Wright, Drives Products Service Manager for ABB in the UK explains how.

DC Motor Carbon Brushes for Elevators: Composition, Function, Solutions

The motor carbon brush has been a critical component in variable speed rotating equipment for over 100 years. The trend towards reduced maintenance has resulted in the elimination of many well established procedures related to carbon brushes. Today new technology is attempting to replace this component and permanently eliminate these maintenance costs. However, when subjected to the proper operating conditions carbon brushes do yield excellent life and perform an amazing function.

Better Mixer Maintenance Ensures Cleaner Effluent at Smurfit-Stone

A preventive maintenance program adopted at the mill has clearly improved the reliability of 16 raft-mounted mixers that help stimulate the biological treatment process removing organic solids from process effluent. The proactive approach to maintaining the mixers, utilizing factory-authorized service, has corrected problems with the previously rebuilt units and delivered significant savings to the mill.

Power Quality Testing Can Reduce Costs

Predictive maintenance (PdM) techniques are commonly used on motors and drives. But how often is the power to the equipment inspected? Adding basic power quality measurements to equipment maintenance procedures can head off unexpected failures in both the equipment and the power system.

Power Company Foresees Failures

Predictive maintenance helps Calpine reduce forced outages and cut MRO costs. The challenge for energy producers to supply continuous, uninterrupted power to customers is constant. Forced outages, which usually occur because of unexpected component failures or systemic problems, can prove costly to the power supplier and undermine its effort to attract and maintain satisfied customers.
