50-295 (hp)

Advantages and Characteristics:

• Can save more than 30% of the electricity;
• The low-pressure air end can automatically adjust the internal compression ratio according to the service pressure and maintain the best energy efficiency within the exhaust pressure range of 2-5bar;
• In many industries, such as chemical, glass, petroleum, textile, printing, dyeing, and ceramics, the required working pressure of compressed air is only 3-5bar. However, at present, these industries usually use 7-10bar air compressors coupling with a pressure reducing valve to achieve low pressure; it is undoubtedly a considerable waste of energy. For this reason, UCS has developed low-pressure screw air compressor which directly outputs the low-pressure compressed air required by these industries; the compressor uses less energy to meet the production requirement, and user's production cost will significantly improve.

Mechanical System

Self-Developed Special Air End

• International leading molded lining, 4:6 tooth ratio, less tooth and more air suction;
• Large rotor, low speed, and long life;
• The inner oil circuit of the air end can precisely control the amount of oil injection, helping the lubrication and cooling reach the best performance;
• SKF bearings adapted to the load changing, which is flexible, efficient, proven long durability, and it guarantees the life of the air end.

Low Pressure Screw Air End Drive Chain

• The high-efficient driving motor directly connected to the two-stage compression air end without coupling, the transmission chain is maintenance-free, reducing energy consumption by 1%;
• IP55 fully closed motor and air end housing integrated, effectively prevents metal particles, dust, moisture and other pollutants infiltrating into the motor and air end, makes the compressor performance more stable;
• The motor bearing uses strengthened cylinder + ball bearing, delivering higher strength and reliability;
• The machining accuracy of transmission gear up to aviation level 6, multi-channel heat treatment and related processing technology ensure the superior surface hardness, ultra-high wear resistance and yield strength of all mechanical components;
• Independent oil supply system and precise oil filtration effectively ensure the stability and reliability of the entire transmission under the long-time operation of full load.

Lubricating Oil:

UCS lubricating oil has good oxidation resistance, high-temperature resistance, high flash point, excellent thermal conductivity and many other characteristics.



Cooling System:

• The design allowance of heat exchange is 20%-50%, which ensures the stable operation of the compressor in an extreme environment and minimize pressure drop.
• Standard motor frequency conversion, accurate oil temperature control, further reduce air compressor energy consumption.

Features of Permanent Magnet Synchronous Motor (PMSM)

• The motor efficiency is as high as 96%, and the power factor is 0.98, far exceeding the level 1 energy efficiency standard;
• Permanent magnet with high coerce and high-temperature resistance ensures no demagnetization at a high temperature of 180ºC;
• Independent fan cooling , to ensure the motor safe running under long hours and low frequency;
• F grade insulation, 70K temperature rise design, suits the high temperature working condition of air compressor ;
• Fully enclosed IP55 protection projects the clean internal environment of the motor and extends the life of permanent magnet and insulation;
• Built-in temperature protection protects winding insulation and permanent magnet.

Permanent Magnet Synchronous Motor Vs Ordinary Asynchronous Motor

High efficiency:

The excitation system loss eliminated, improving efficiency.
 

Large starting torque:

More stable control: 

• Ultra-low temperature rise design, to allow compressor long-term low-frequency stable operation;
• Adopting the open-loop vector control system . it controls faster, and the speed regulation is more accurate;
• When the frequency is reduced by more than 50%, the compressor unit can still operate efficently;
• Stable pressure accurately controls pressure fluctuation within 0.01mpa; With soft-start characteristic, avoid start current shock, reduce start energy consumption.

Modular Vector Frequency Drive (VFD)

Large redundant heat design , more stable operation and longer equipment life under severe service environment;
No stop at an instantaneous stop, over-excitation protection and many other excellent functions to deal with various emergencies;
Built-in PLC and a variety of communication interfaces, more convenient to use and maintain;
Wide range of speed regulation, high accuracy of speed stability, deliver stable operation with on-load at an ultra-low speed of 0.01Hz.

UNITED COMPRESSOR SYSTEMS has a series of screw compressors with the power of 5.5~630kW, FAD of 0.69~120m3/min and pressure range of 0.2~1.5MPa. At UCS, we also provide services such as design, manufacturing, training operation of the air compression station, technological improvement of energy-saving and customized types. The idea of wholeheartedly customer serving makes our pace steady and long.

To save space and install pipelines, the series of intelligent all-in-one screw compressor produced by UCS integrates compressor, air storage tank, refrigerated dryer and filter into one unit, which is equivalent to a miniature air compressor station. The machine popularly used in dentistry, hyperbaric oxygen chamber, laboratory, electronics, semiconductor, winery, beverage, food packaging, laser cutting, and other industries were requiring pure air and small-scale air supply.

Quality Assurance

In 2003, UCS Compressor accredited with ISO9001 Quality Management System and ISO14001 Environmental Management System Certificates. The company strictly follows the quality requirement of Crosby's "doing it right the first time", persists in the working standard of "zero defect", regards the "It is immoral to produce a defective product" as the criteria of measuring the quality. UCS devotes itself to the continuous improvement of products all the time.
