Kieran Doyle, managing director at Oilgear, explores the innate features and processes that can ensure hydraulic pump
performance is not simply defined by basic certification, but offers further benefits to the application that reduce the risks of downtime.
The launch from the Cape Canaveral Air Force Station in Florida was cancelled because of a faulty hydraulic pump
, NASA said.
Backed by a one-year parts warranty, the units feature a foot-operated hydraulic pump
to raise and lower the platform, and stainless hydraulic pump
body, lift piston and wheel lock.
After departure, landing gear only partially retracted and hydraulic pump
Traditionally most machines were hydraulically driven, whereby a hydraulic pump
driven by a fixed (constant-speed) electric motor powered most of the machines' processes.
Controlling hydraulic units with servo motors also allows the servo motor to act as a generator and recover energy every time pressure is reduced in the hydraulic pump
. Milacron says that it recovers 16% of clamping energy this way on its Maxima two-platen machines, which were converted from hydraulic to servo hydraulic four years ago.
A lot of hydraulic pump
assemblies, NSN 4320-01-579-1044, on the M978A4 HEMTT have failed.
10 that Boeing changed the design of a hydraulic pump
that failed on its 787 Dreamliner in recent weeks, causing the $200 million high-tech plane to be taken out of service for two weeks.
He told me to activate a hydraulic pump
, which restored the accumulator.
The hydraulic pump
test rig has an electric motor drive with computer-controlled speed, as well as the capability to handle up to 250 bar of pressure and lO,O00rpm.
The system controller and hydraulic pump
can be mounted remotely or on the exterior of the safety cage, and require only an electrical power connection for operation.
