Water Cooling Screw Air Compressor

In order to ensure the efficient operation of the water-cooled screw air compressor, in the design, emphasis is placed on the chiller, overcurrent relay, compressor motor temperature sensor, anti-freezing thermostat, sight glass, and oil heating of the screw air compressor. Compressor, compressor reverse phase protection relay, high and low pressure protection, exhaust high temperature protection, safety valve, soluble plug and other components quality. Due to the high quality of these components, it is safer and easier for the user to use.

  • Adopt special low-pressure screw main engine to reduce energy consumption costs
  • High efficiency, environmental protection and energy saving
  • No wearing parts, more durable
  • Adopt high-efficiency oil and gas separation system to ensure that the oil content of the air compressor is low
  • Stable and low noise

Description
  • The advantages of water cooled screw air compressors are simply: high reliability, high operating efficiency, easy maintenance, easy control, strong adaptability, low noise, and good display system.
  • It is said that its stable operation and high efficiency are because its rotor adopts the latest asymmetric design. 
  • Facts have proved that this design method can effectively improve the stability and efficiency ofscrew air compressor operation.
  • The design adopts the stepless capacity control system, which makes the operation easier. Another reason is because of its powerful display system. 
  • The water-cooled screw air compressor adopts a large-screen dot matrix liquid crystal display, and has a good full Chinese man machine dialogue interface to realize full function automatic control. 
  • The liquid crystal display screen displays the working status of the machine in real time, and the precise chiller is running in the best state. 
  • The panel is well sealed, waterproof, dustproof, anti-corrosion, and has a long key life. 
  • Because the display can show the operating status of the screw air compressor at all times, the operation difficulty of the air compressor is greatly reduced.

    More Details
  • The permanent magnet motor and the compressor host adopt the built-in integrated shaft direct connection structure, and the structure is more compact.  There is no motor bearing, the rotor with permanent magnets is directly mounted on the protruding shaft of the male rotor,  eliminating the fault point of the motor bearing.
  • The permanent magnet synchronous motor adopts high-performance NdFeB permanent magnets; the stator coil adopts corona-resistant enameled wire specially designed for inverter, which has excellent insulation performance and longer service life;
  • Intelligent dynamic control, dynamic display of the working conditions of each component of the compressor, real-time and intuitive working curves of pressure, temperature and current;
  • Large-capacity oil and gas separator, high-quality oil and gas separation elements and gas and liquid filter elements, with three oil and gas separation, low oil content,  to ensure the high quality of compressed air
  • Adopt large heat exchange area design, improve cooling efficiency, effectively prevent high temperature of the machine, and do anti-corrosion treatment on the inner wall to adapt to harsher working conditions and prolong service life.

    The system adopts stepless adjustment of 0-100% displacement. When the air consumption is reduced, the exhaust volume is also reduced, and the current of the motor is also reduced at the same time; when the air is not used, the air compressor runs empty, and the air compressor is automatically stopped for a long time. When the gas consumption increases, resume the heavy vehicle. The best energy saving effect. The extraordinary cooling system design is especially suitable for high temperature and high humidity environment. Excellent vibration isolation technology and noise reduction measures, no special foundation is required for installation, as long as the minimum ventilation and maintenance space is left, your compressor can be installed.
