Part 1 - Hands On
In-Plant 3-Day Basic Hydraulic Troubleshooting
This comprehensive 3-day workshop is specifically designed for electricians, millwrights, supervisors, and reliability technicians who are responsible for maintaining hydraulic systems. The workshop covers the five fundamental aspects that a hydraulic troubleshooter must know, including the function of each component, how to read schematic symbols, how to troubleshoot each component, how to properly adjust pressure for maximum efficiency, and the correct troubleshooting checks to make. The training program is designed to provide a hands-on troubleshooting experience in both the classroom and the plant. In the field exercise, the students will use some of the troubleshooting techniques learned in the workshop, on their actual systems. All of our courses are taught using layman terms and from a troubleshooting point of view, ensuring that participants can easily comprehend and apply the concepts covered.
Part 2 - Hands On
Customized In-Plant Machine Specific Hydraulic System Troubleshooting - Course Length 2 - 4 Days
This program involves conducting a thorough survey of the hydraulic system, which includes updating schematics and taking pictures of each component. The schematics are then redrawn to integrate the electrical control and hydraulic flow, and a detailed description is written for each component, outlining its function, troubleshooting, and adjustments. The training program is designed to provide hands-on experience in both the classroom and the plant, allowing students to gain a deep understanding of the in-plant' electrical and hydraulic function. The students will participate in component identification and Pdm checks on their hydraulic machines. Upon completion of the program, students will be equipped with the knowledge and skills necessary to troubleshoot hydraulic problems using their own troubleshooting manual.
Troubleshooting Proportional Valves
Hands-On In-Plant Workshop
Course Length -6 hours
Proportional valves are many times changed without any tests being performed. In addition, the adjustments on the amplifier or in the PLC are often made without consideration given to how the hydraulic system will be affected. This can be expensive, both in parts cost and plant downtime. In many cases, hours are spent just determining if there is an electrical or hydraulic problem. After attending this 6-hour course, the maintenance personnel will know:
• The function of the three electrical signals fed into a proportional valve amplifier.
• The purpose of the LVDT (linear variable differential transformer) located on the proportional valve.
• How to check the LVDT feedback signal.
• How to mechanically and electrically null a direct operated valve.
• The function of the hydrostat when used with a proportional valve.
• The function of the lights and adjustments on the amplifier.
• How to check the power supply, enable, command and LVDT feedback signals.
• How to troubleshoot the direct operated proportional valve.
• The purpose and location of the Allen head plugs in a two-stage valve.
• How to convert externally piloted and drained valves into internally piloted and drained valves
• How to check the electrical inputs and outputs on a two-stage valve amplifier.
• How to electrically and mechanically null a two-stage valve.
• How the cylinders linear positioner operates.
• How to drive and troubleshoot a proportional valve with a test box.

Part 3 - Hands On
Boots On The Ground Machine Specific Hydraulic System Troubleshooting - Course
Length 1- 3 Days
Our " Boots on the Ground" In-Plant Hydraulics Workshops are designed and taught directly on your plant's actual systems.The program begins with a pretest to assess the students' basic knowledge of hydraulic fundamentals and hydraulic component function, followed by classroom preparation for on-floor troubleshooting exercises.
During the hands-on portion, students will conduct a thorough Predictive Maintenance (PdM) inspection on their hydraulic systems. Specific tasks include checking for leaks and excessive shock, verifying relief valves are not bypassing, ensuring correct accumulator charges, verify correct pressure settings, and identifying max/min strokes for high-pressure pumps. Any identified leaks will be tagged for repair and excessive shock.
Throughout the training, classroom time will be dedicated to reviewing findings and addressing questions. The instructor will lead the team to ensure the root causes of the shock, leakage etc. is determined and to build the teams confidence and understanding of the hydraulic system.
Finally, where possible without interrupting production, field adjustments may be made to reduce shock and leakage. Students will compile a comprehensive list of problem areas, which the instructor will distribute to the appropriate personnel.
