Cut Section Model of Open Hermetic Compressor
A cut section display model of an open hermetic compressor showing internal components and valve mechanism.
Overview
The Cut Section Model of an Open Hermetic Compressor is a precision cut-section display unit that reveals the internal construction of an open-type hermetic reciprocating compressor used in refrigeration systems. All internal components including the piston, connecting rod, crankshaft, reed valves (suction and discharge), valve plates, motor windings, and oil lubrication system are exposed and colour-coded for identification. The model is driven by a slow-speed electric motor to demonstrate the valve operation and piston motion, helping students understand compressor mechanics before studying compressor performance on live refrigeration test rigs. It is an essential visual aid for refrigeration engineering laboratory and lecture demonstrations.
