That system was not meeting its "prescribed pressures," which suggested a problem with the hydraulic pump
DIRECT SERVO DRIVE: The newest addition to the company's Sytronix SVP servomotor drives for hydraulic pumps
is the model MS2N, which is directly coupled to the pump--which Bosch Rexroth says is unusual for servomotors.
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
Units can get a new and improved hydraulic pump
assembly, NSN 4320-01-618-6603, at no cost through the Oshkosh warranty claim process.
CAUTION--Prolonged use of a failed hydraulic pump
without the pump shaft shearing as indicated by the needle not stabilized at zero will generate considerable heat and may result in an AMAD bay fire.
The EX2600-6 also offers the improved hydraulic pump
output performance and improved hydraulic oil cooler design included in its larger sibling.
Full hydraulic systems can be put through reliability and performance testing on a dedicated test bench, which features a dummy gearbox for gearshift actuator analysis, up to 180oc conditioned oil an electro motor-driven hydraulic pump
with 10,000rpm capability and control of six servo valves.
The circuit consists of unregulated axial piston hydraulic motor and regulated hydraulic pump
with an inclined cylinder block.
The new PosiTest AT-A Automatic Adhesion Tester, with a full digital keypad, measures adhesion of coatings to wood and wood products, and now features an electronically controlled hydraulic pump
The engine drives a hydraulic pump
that drives the wedge.
The HPP-10K hydraulic pump
can generate pressure from 0 to 690 bar (0 to 10,000 psi).
The larger diesel engines are also required to drive the refuse body hydraulic pump
at low speed when substantial low-speed horsepower and torque is required.
SrA Jacobson quickly discovered the hydraulic pump
and associated lines would "jump" whenever the flight controls were activated.
Operators using the new joystick controls will be able to use a yellow proportional thumb switch to control the variable flow auxiliary hydraulic pump
If required, the hydraulic pump
system can be remotely located so that the bale cutter occupies a minimal amount of floor space.
