INDS 254 - Advanced Hydraulics

3 Credit: (1 lecture, 2 open-lab, 0 clinical) 3 Contact Hours: [INDS 107  or INDS 253 ]

1. Read, interpret and apply fluid power graphic symbols and drawings.
2. Apply advanced concepts of fluid power to power pumps and motors.
3. Apply advanced concepts of actuators for power transmission.
4. Analyze and troubleshoot advanced fluid power circuits.

Goal 2:  Develop and construct a sequence of operation for hydraulic circuits.

1. Control the sequence of two cylinders with a sequence valve.
2. Control the sequencing of a cylinder and motor with a sequence valve.
3. Operate directional control valves.
4. Adjust valve settings for optimal operation.

Goal 3:  Develop and construct extension speed control methods for hydraulic circuits.

1. Implement a regenerative circuit to increase the extension speed of a cylinder.
2. Implement a circuit to increase the extension speed of a cylinder to have full force available at the end of its stroke.
3. Apply an externally piloted counterbalance valve to unload a regenerative circuit.
4. Adjust pressure settings of valves.
5. Provide an adjustable extension speed by metering the amount of flow leaving the rod end of a cylinder.
6. Apply a restrictor type flow control valve as a “meter-out” circuit to control a resistive load.

Goal 4:  Develop and construct retraction speed control methods for hydraulic circuits.

1. Provide an adjustable retraction speed by metering the amount of flow into the rod end of a cylinder.
2. Apply a restrictor type flow control valve as a “meter-in” circuit to control an overrunning load.
3. Provide an adjustable retraction speed by metering the amount of flow into the cap end of a cylinder.
4. Apply a restrictor type flow control valve as a “meter-out” circuit to control an overrunning load.
5. Apply a restrictor-type flow control valve as a “meter-in” application with a counterbalance valve to control an overrunning load.
