75kw 100hp Fixed Speed Air Cooled Direct Drive Twin 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. 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)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

5)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

5. Helpful Air Compressor Definitions

• Pounds per Square Inch (PSI) — the measurement of air pressure and force that is delivered by an air compressor. Higher numbers mean that a larger volume of air can be compressed in the tank.

• Pounds per Square Inch Gauge (PSIG) — the measurement of air pressure and force that is delivered by an air compressor relative to our atmospheric pressure at sea level, which is 14.7 PSI. Most gauges are calibrated to read 0 at sea level so the 14.7 psi of the earth’s atmosphere is not measured.

• Actual Cubic Feet per Minute (ACFM) — the actual volume of air pumped in one minute from a compressor running at its rated operating conditions of speed, pressures and temperatures.

• Standard Cubic Feet per Minute (SCFM) — the representation of the volume of air pumped in one minute at 60 degrees Fahrenheit (15.6 degrees Celsius). Some air compressors will be rated with SCFM to provide a more accurate working rating since air contracts and expands at different temperatures.

• Horsepower (HP) — the measurement of power the motor produces. The higher the number, the more work the air compressor can do to deliver a greater PSI and ACFM.

• Brake Horsepower —Horsepower delivered to the output shaft of a motor or engine, or the horsepower required at the compressor shaft to perform work.

• Indicated Horsepower —The horsepower calculated from compressor indicator diagrams. The term applies only to displacement type compressors.

• Intercooler — part of the air compressor that cools air between compression stages.

• Aftercooler — a heat exchanger used for cooling air discharged from a compressor. Resulting condensation may be removed by a moisture separator following the aftercooler.

• Pneumatic Tools — tools that operate by air pressure.

• Positive displacement compressors —Compressors in which successive volumes of air or gas are confined within a closed space and the space is mechanically reduced, resulting in compression. These may be reciprocating or rotating.
