55kw 75hp Electric Air Cooling Direct Drive Screw Air Compressor
1. Product Profiles
The direct driven screw air compressor transmits electric power to
the airend through a flexible coupling, it consumes almost no
energy in the transmit process, so that direct driven is the most
efficient transmission mode.
2. Advantages
(1).There is no intermediate drive, so there is no energy loss.
(2).Larger rotors operate at lower speeds, so it is more efficient
and further reducing energy consumption.
(3).It avoids some shortcomings of belt driven air compressor, such
as unbalanced force, easy to generate heat, the belt is easy to
break, frequent belt change, and need to re-adjust the level of the
pulley and the tension of the belt frequently.
(4).Due to the coaxial transmission of the flexible coupling, the
force is balanced and the vibration is reduced, which increases the
reliability and reduces the maintenance cost.
3. Main Parts
1) Airend
Air end is equipped with lasted rotors with bigger diameter and low
rotate speed, high –quality SKF over loading bearing and three
special oil seals guarantee the high efficiency, reliability and
durability.
2)PLC intelligent control system
Human-based English user interface: remote control and several
compressors interconnected; running state; automatic protective
alarm.
3)Automatic adjustment intake value
Adopting 0-100% inlet proportional intake valve which stable the
work pressure and save energy.
4)Specific screw compressor motor
◆ IP54, F Class
◆ SKF over-loading bearing
◆ Service Factor: SF=1.2
◆ Low noise, long use life
◆ Voltage and Frequency can be customized
5)High-efficiency Filter System
◆ High-efficiency air filter, filter the air of dust and
impurities, filtration come to 98.5%
◆ Branded oil filter, filter the air of oil, guarantee the long
time use life of airend
◆Oil-Air Separator element, high-efficient separation, oil contact
less than 3ppm
◆ Regular maintenance notice and alarm by PLC
6)Control System
◆ ABB brand electrical components, including breakers, AC
contactors, reliable, easy to replace
◆ MICROCHIP with Standard 485 interface, it can achieve remote
monitoring according via MODBUS communication protocol
◆Collection the signals of compressor electrical , exhaust,
temperature , pressure to monitor the operational status , but also
help for quick troubleshooting
7)High-efficiency Cooler
◆ Integrated design of air cooler and oil cooler, compacted
structure, small size with lower weight
◆ high- efficient heat transfer, guarantee the best cooling effect
◆ Water cooling is available
