Hydraulic Motor Test Stand

When complete, the system will plot flow, rpm, torque, and efficiency of the motor at various pressures.  A determination will then be made to pass or fail the motor.

The operator will also place a motor in the flushing section of the stand.  He will attach the hoses and press a start button to initialize the break in / flushing operation. An electric motor / gearbox system will start turning the motor  at 10 rpm while hydraulic oil will be fed to the motor at approximately 750 psi.  The motor will be flushed with hydraulic oil for approximately 60 seconds.  The hydraulic oil will be directed into a bag type filter where particles greater than 50 microns will be captured.  A screw on polishing filter will be downstream of the bag filter to capture smaller particles until the oil is returned to the main cooling system.
This system performs a break-in / flush cycle for a hydraulic motor.  The motor is then scanned and tested to parameters obtained from an SQL query to the company's central storage system.  An eddy current brake with speed increasing planetary gear drive is used to apply up to 15,000 in.lb. torque dynamically to the motor.  Speeds, flows, and pressures are then taken and the motor is deemed to pass or fail based on parameters provided by the central system.
