Hydraulic System Maintenance and Troubleshooting for Coiled Tubing
Hydraulic System Maintenance & Troubleshooting for Coiled Tubing
Would a deeper understanding of injector control and reel drag hydraulics help you with your troubleshooting?
This course is designed to be the first step in rigorous hydraulics training for coiled tubing operations and maintenance personnel. Participants come away from this highly concentrated course with a solid understanding of hydraulic principles, as well as component design and functions. System analysis and troubleshooting skills are taught using the circuits and schematics on a coiled tubing unit.
The Ten Step Troubleshooting Process is taught with the goal of eliminating the “hit or miss” methods that can be so costly in terms of time and materials. Safety is stressed along with sound maintenance practices. This three-day course is taught with circuit simulation software and through instructor guided hands-on study of individual hydraulic components.
Learn How To:
- Interpret coiled tubing unit schematics
- Think and act in a logical way when the system goes down
- Conduct basic system tests
- Analyze open and closed loop injector circuits
- Analyze reel drag and traction circuit problems
- Diagnose electric-over-hydraulic pump stroking problems
- Follow correct system setup procedures
