2.4 Design features
HANBELL screw compressors feature simple and robust construction by elimination of some components such as
pistons, piston rings, valve plates, oil pumps which are found in reciprocating compressors. Without these components,
screw compressors run with low noise level, minimized vibration, high reliability and durability. HANBELL screw
compressors are of two-shaft rotary displacement design with the latest and advanced 5:6 patented screw rotors.
Screw rotors are precisely installed with roller bearings, i.e. radial bearings at both suction and discharge ends as well
as angular contact ball bearings i.e. axial bearings at discharge end. A three-phase, two-pole squirrel-cage induction
motor drives the compressor. The motor rotor is located on the shaft of the male screw rotor. Cooling of the motor is
achieved with suction refrigerant vapor.
Compressor technical features:
Full product range- RC2-V series compressor consists of 26 models with displacement ranging from 98 m
3
/hr up to
1539 m
3
/hr at 50Hz.
Multinational patents of high-efficiency screw rotors
- The new 5:6 high efficiency screw rotor profile is patented in
Taiwan, UK, US, and China. This new large-volume, high-efficiency rotor profile is designed especially for modern refrigerant
characteristics. High-efficiency screw rotors are accomplished by using precision CNC machining centers, rotor milling machines,
rotor grinding machines. Strict ISO 9001 process controlling and the application of precise inspection equipments, such as ZEISS
3D coordinate measuring machines, ensure high-efficiency, high-quality, low-noise and low-vibration HANBELL RC2-V series
screw compressors.
High efficiency motor- Premium grade low-loss core steel with special motor cooling slot and refrigerant guide vane
which pilot the cold suction refrigerant gas through the motor provides the highest operating efficiency possible no
matter how strict operating conditions are. The winding and insulation is especially made for variable speed drive
application.
Long life bearings and high reliability- RC2-AV screw compressors utilize precise axial and radial bearings and
α
axial balance piston to ensure longer bearing life and higher compressor reliability.
