College Credits: Paul Bligdon Page 1 Industrial Hydraulics for Colleges Intro College Course Title: Lab Title: Typical Hydraulic Circuit Student Name: Section Number: Instructor: Paul Bligdon
College Credits: Paul Bligdon Page 2 Industrial Hydraulics for Colleges Intro Lab Exercise Typical Hydraulic Circuit This lab introduces the student to the Parker Hydraulic Training Bench and the installation of a typical hydraulic circuit on the benches’ “backboard”. Prior to the installation of the typical hydraulic circuit; the student will turn the hydraulic system “ON” and “Set” the Relief Valve to minimize the maximum pressure obt ainable by the circuit and measure the rate of flow in gallons being produced by the hydraulic Pump. The student will then turn the training bench “off” and proceed to install the typical hydraulic circuit illustrated in Procedure 2. Once the circuit has been installed and verified by the instructor as correct, the student will proceed to operate the circuit as directed by the lab instructions while observing and recording circuit measurements and operational sequences. Upon completion of the lab, the student will be able to perform various hydraulic system calculation commonly required during the design stages of hydraulic circuitry. As part of the lab submission, the student will be required to draw the ANSI schematic for the lab circuit and answer the review questions . Learning Outcomes Work in compliance with the Ontario //Health and Safety Act and the College’s Safety Standards during the performance of the lab exercise. Follow written technical instructions to perform work tasks Using standard ANSI symbols, sketch the schematic diagram of the lab’s hydraulic circuit Create a hydraulic symbol library in Auto Cad Using Auto Cad, draw the schematic diagram of the lab’s hydraulic circuit. Troubleshoot circuit operation as required Observe the hydraulic principles of flow, pressure and resistance Perform hydraulic calculations based on data collected during the lab. Describe the basic operation and function of typical hydraulic components
College Credits: Paul Bligdon Page 3 Industrial Hydraulics for Colleges Intro Procedure 1: Setting the Relief Valve Note: The relief valve can be adjusted and set without the any additional circuitry being added to the bench 1. Ensure that the PDP panel is in the “off” position and the Emergency Stop Button is “depressed” before proceeding 2. Ensure that the Vent Shut-off Handle (yellow) is in its horizontal position. (zero pressure) 3. Turn the Relief Valves Adjustment Knob fully counter clockwise. (lowest spring setting) 4. Release the Emergency Stop Button 5. Following the learned safety procedure, turn the PNP panel’s switch to the “ON” position 6. Depress the Training Benches’ Start Push Button (|green) 7. Record the pressure indicated on the System’s Main Pressure Gauge (PGM) PSI . 8. Turn the Vent Shut-off Handle (yellow) to its vertical position (maximum pressure) 9. Slowly turn the Relief Valve’s A djusting Knob clockwise. 10. Continue to turn the Relief Valve’s Adjusting Knob Before connecting the circuit, set the relief valve to its maximum setting based on the bench’s component configuration PSI = Note : The pressure created by the circuit is being limited by the relief valve at this time as there is no flow path from the pump to the reservoir without going through the relief valve. As the adjusting Knob on the relief Valve is adjusted Clockwise, the resistance to flow through the valve increase. An increase in resistance causes an increase in the pressure required to push the fluid through the valve. 11. Turn the Vent Shut-off Handle to the horizontal position 12. Record the pressure seen on PGM. psi 13. Depress the Training Benches Motor Stop Button (red) 14. Depress the Emergency Stop Button 15. Turn the PDP switch to the Off position
College Credits: Paul Bligdon Page 4 Industrial Hydraulics for Colleges Intro Procedure 2: Assembling the circuit 16. Ensure that the PDP switch is in the “off” position and the Emergency Stop Button is “depressed” before proceeding to install your circuit. 17. Identify the areas of the hydraulic training bench referred to as the Back Board and the Power Unit 18. Using the ANSI schematic circuit located below, note that the POWER UNIT COMPONENTS are permanently configured and connected together. See the ANSI Schematic Drawing below to identify the typical hydraulic components which make up the POWER UNIT for the training bench. Yellow Handle
