Construction of screw compressor
HANBELL semi-hermetic twin-screw compressors are constructed with the following three major components; the compressor compartment, the hermetic motor compartment and the oil separator compartment.
- The compressor compartment includes twin-screw helical rotors, bearings and components for capacity control system.
- The hermetic motor compartment includes the motor stator, motor rotor, six terminal plugs for electric power connections, an internal thermostat inserted into the stator coil toprotect the motor from burning out, two terminal plugs for the thermostat, and a suction gas strainer.
- The oil separator compartment consists of demister and chambers to serve as an oil separator and an oil reservoir. The rotor of the hermetic motor is connected directly at the suction end of the male rotor shaft and drives the rotor shaft at rated speed of 2,950 rpm at 50 Hz and 3,550 rpm at 60 Hz respectively.
