🔍 Key Concepts

• Function of an unloader on a ship service air compressor during start-up and stopping • Relationship between compressor load, motor starting torque, and belt drive systems • Difference between a problem with pressure control vs. a problem with unloading

💭 Think About

• Ask yourself: What is the unloader supposed to do to the compressor cylinders when the unit starts and stops? • If the compressor does NOT unload, what condition will the prime mover and drive system experience at the instant of starting? • Which option describes a direct mechanical or operational consequence of starting a compressor fully loaded against system pressure?

✅ Before You Answer

• Be clear on the difference between pressure too high / too low in the receiver and starting load on the compressor. • Check which choices describe an effect that happens right at start-up versus something that would happen only after running for a while. • Verify which option reflects extra mechanical strain on the drive when the compressor starts under full pressure.
