“We don’t believe it!” – that’s how experienced machinists at Waltz Brothers Inc., a precision grinding and machining operation producing flight-critical hydraulic pumps, reacted to their first encounter with the Sunnen SV-1015, a honing systems that had produced nine bores per part with only 0.000020 in. (0.5 µm) variation, all day long, with essentially no […]
Altair Engineering has selected Parker Hannifin’s series hybrid hydraulic drive system for its BUSolutions project. The system will enable the new advanced bus platform to achieve 45-70% increased fuel economy over average diesel powertrains and more than double the fuel economy improvement of hybrid-electrics.
Designing a hydraulic control system involves several design considerations and tradeoffs. Key among them are selecting the proper system components and setting up the motion controller with the proper control algorithm.
Three types of systems are commonly used in mobile applications: constant-flow (CF), constant-pressure (CP), and load-sensing (LS) systems.
