🔍 Key Concepts

• Mechanical unloading systems on reciprocating/rotary air compressors • How receiver air pressure is used to control unloaders and pressure switches • The relationship between starting load on the compressor and motor current/overload protection

💭 Think About

• What does a mechanical unloading system actually use to hold the compressor unloaded – is it dependent on existing receiver pressure, compressor discharge, or something else? • If the receiver is completely empty, what condition exists at start-up: maximum pressure, minimum pressure, or no pressure? How would that affect the unloader’s ability to operate? • If the compressor starts with little or no air pressure in the system, is the motor under heavy load or light load during the first few revolutions?

✅ Before You Answer

• Clarify whether the unloader needs pre-existing receiver pressure to function or if it operates from compressor discharge on start-up • Think through whether a no-air / no-pressure condition would make it easier or harder for the motor to turn the compressor at start • Consider what condition would actually cause a circuit breaker trip: high starting load or very low/no load on the compressor?
