Use It or Lose It

We are planning on making a system more efficient here at the steel mill. Two overdesigned hydraulic power units are each operating continuously 24/7. Each one …

Something Is Missing: Using Alternative Energy

There is something missing in my repertoire of fluid power components. Can you help me? In the Off-Highway 2010 edition of the Fluid Power Journal, Brian …

A Failed Experiment

Now, don’t get discouraged. When we push the envelope trying to change the paradigm of thinking in the transfer of energy in fluid power systems, we will …

System Integrators Energy Challenge: Follow Up

There are some prerequisites for reading this article: you need to read last month’s article entitled “System Integrators: An Energy Challenge,” you need …

System Integrators: An Energy Challenge

I have to admit that I am a little bit skeptical. Now, don’t get me wrong. I am not saying that system integrators don’t know anything about saving …

Reducing Pressure: A Way to Save or Waste Energy?

If you are a pneumatics person, you will be thinking of a pressure regulator; the hydraulic people among us will be thinking of pressure-reducing valves. In …

Outside the Box

I’ve got an idea. Tell me what you think. You have an application where you need to store 20 liters of hydraulic fluid to be used at 120 bar. You know that …

Simulating a Piezoelectric-Actuated Hydraulic Pump Design

Hydraulic pumps are often the focus of automotive engineers attempting to reduce energy losses. For example, power steering systems have progressed from purely …

Pump Drive Retrofit: Key to Energy Savings in Hydraulic Stamping Presses

Stamping presses that form and bend metal under pressure are themselves under pressure to improve throughput, process cost control, and energy efficiency. Many …

Take Your Hydraulic Systems Off Life Support

Contamination in hydraulic fluid is responsible for more than 80% of hydraulic system issues. The most cost-effective method of increasing the lifetime of …
