Adapters extend pump life
Overhung load adaptors, inset, help ensure the life and reliability of hydraulic pumps in Roadtec's asphalt repaving machines, such as this RX 50B, their largest. Repaving asphalt roadways requires stripping off the old layers of ...
Instructors learn of "boring" subject
This pair of 14-in. bore hydraulic cylinders, along with a pair on the other side, provides forward thrust and steers the cutter head. Together, these cylinders produce 1.5 million lb of thrust. Complete tunnel boring machine consists of ...
Cv — an essential design and diagnostic tool
Every pneumatic device possesses a specific conductance, identified as Cv . Because Cv is perceived as a complex expression, many designers avoid learning about it and, hence, become ignorant of its importance and proper application. Pneumatic ...
All about cylinder cushioning
Fig. 1. Every cylinder has a single setting for ideal cushioning for a given load and operating pressure. Too much cushioning increases the time it takes for the piston to reach the end of its stroke; too little cushioning increases ...
Is air lubrication still practical?
Deciding which, if any, type of lubricator to use in a compressed air system must address performance, maintenance, safety and the workplace environment.
Unconventional HPUs make machines energy misers
Edited by: Alan L. Hitchcox This HPU breaks from convention by using a fixed-displacement pump and variable-speed electric drive to match pump output to load demand. The control box at right houses electronic controls for interfacing with ...
Hydraulic hybrids on the horizon
President Bush recently spoke about an initiative to develop better gasoline-electric hybrid vehicles. Prior to that, Consumer Reports magazine reported that these hybrids can pose a dilemma for car buyers. On one hand, hybrids do use less gasoline, and ...
Hybrid hydraulics project aims at commercial vehicles
Hybrid electric passenger cars may be hot, but a team of researchers at the University of Toledo is working to fine-tune a hydraulic-based hybrid system for refuse trucks, delivery trucks, and other heavy vehicles that make stop and go ...
Passion lives here
You may recognize the headline to this page as the theme of the 2006 Winter Olympics. I think a similar theme could've been used for the 5th International Fluid Power Conference, held last month in Aachen, Germany. I have known of the IFK (as it is ...
A primer on cylinder tubing
The pressure-containing envelope (barrel) of hydraulic cylinders and other metal fluid power components are made from a variety of ferrous and non-ferrous materials. In ferrous, the use of low-carbon 1026 steel (UNS G 10260) has been supplanted ...
