SC 210 Screw Compressor Oil Systems

SC 210 – Compressor Oil Systems

SC 210 provides a detailed, technician‑level understanding of oil systems used in oil‑flooded screw compressors. The course focuses on how oil supports compressor reliability, efficiency, and capacity control—and what happens when oil systems are misunderstood or misapplied.

This course is intended for:

• Industrial refrigeration technicians and mechanics
• Operators responsible for compressor reliability
• Engineers supporting system troubleshooting and optimization
• Anyone working with oil‑flooded screw compressors

Students learn how oil performs far more than lubrication. The course explains oil’s role in sealing compression chambers, cooling the compressor, powering hydraulic systems, balancing axial loads, and protecting critical bearings.

Course Sections

• Bearings
  Bearing types, gas forces, and lubrication requirements.

• The Oil Cycle
  How oil is separated, cooled, filtered, distributed, and returned.

• Oil Cooling
  External cooling methods and liquid injection oil cooling control.

• Oil Filtration
  Filter ratings, particle sizes, and bearing life relationships.

• Oil Distribution
  Oil flow paths and proper oil injection valve setup.

• Oil Separation
  Separator operation, velocity effects, and head pressure challenges.

• Oil Pumps
  When pumps are needed and the true cost of running them.

• Hydraulics
  How oil power is used to move mechanical components.

• Slide Valve Hydraulics
  Capacity and Vi control using oil and suction pressure.

• The Balance Piston
  Managing axial gas forces and protecting thrust bearings.

Outcome:
After completing SC 210, students can diagnose oil‑related issues confidently, operate compressors within safe limits, and make informed decisions that reduce failures, extend bearing life, and improve system efficiency.
