Powerful Small Rotary Screw Air Compressor / Portable Screw Air Compressor


Small Rotary Screw Air Compressor Feature


Highly efficient magnetic steel of permanent magnetic motor


Punching uses high-performance low-loss silicon, we conduct simulation analysis of mechanical strength with finite element method so as to make rotator inertia reach the minimum on the condition that enough mechanical rigidity and mechanical strength.

Rotator magnetic steel adopts high-performance NdFeB permanent magnetic material to form sine wave air-gap field.

Axial flow uses the processing method of embedded bond, which simultaneously meets requirements of optical axis and bond axis.

Industrial Screw Compressor ADVANTAGES/FEATURES


  • Advanced and energy saved spiral tooth type technology
  • New-type 5:6 asymmetrical rotator tooth type
  • German screw compressor with large rotator and low rotation speed
  • Adopt top-level quality SKF taper-roller bearing imported with original packaging from Sweden
  • Relative power increases by more than 5%-10% in gas discharge when compared with that of ordinary machine model

Magnetic steel

  • Punching uses high-performance low-loss silicon, we conduct simulation analysis of mechanical strength with finite element method so as to make rotator inertia reach the minimum on the condition that enough mechanical rigidity and mechanical strength.
  • Rotator magnetic steel adopts high-performance NdFeB permanent magnetic material to form sine wave air-gap field
  • Axial flow uses the processing method of embedded bond, which simultaneously meets requirements of optical axis and bond axis.

Winding

  • Punching uses high-performance low-consumption silicon steel sheet;
  • Insulation grade of enameled wire is grade C and integral insulation is grade F
  • Shell uses high-intensity aluminum profile shell, appe final optimization through finite element temperature gradient and good heat dissipation effect;

SKF-bearing


Compared with bearings of other brands, SKF bearing, it has good abrasive resistance, superior fatigue resistance, strong corrosion resistance and comfortable muting property, making longer service life, higher reliability and lower noise of permanent magnetic synchronous non-inductive motor.


Infinite volume control air inlet system


The compressor adopts infinite volume control air inlet system. It could operate without magnetic valve. Built-in function of the check valve can reduce malfunctions. The compressor is free from unloading process and shows higher energy efficiency. This compressor can operate at frequencies from 0-300HZ and realize high energy efficiency in real sense.


Industrial manager function


Wan Beardsley air compressor system can pre-set weekly work schedule according to your working hours in the factory, air compressor will punctually and automatically power on ana off accordinq to preset working schedule


High-performance vector frequency converter

  • Standard equipment with radio-frequency reactor which effectively reduces magnetic field interference outside high-frequency machine generated by frequency converter;
  • Reliably reduces peak current when it is started, realizes stable starting;
  • Saves cost of electrical power units;equipped with standard dust screen, circuit board is processed with surface coating, so antifouling, anti-dust and damp-proof effects are realized;
  • equipped with standard dust screen, circuit board is processed with surface coating, so antifouling, anti-dust and damp-proof effects are realized;
  • Special heat dissipation design prevents tripping under summer high temperature;
  • Standard protocol of CAN with wire road standard of hardware and strong noise resistance;
  • Rapidly track change of pressure, control pressure fluctuation within ±0.01Mpa, optimal power is used to accurately provide necessary air amount;
  • Advanced integrated draught fan, and motor uses double-vector variable-frequency control technology.

High efficient centrifugal fan-cooling control system of double frequency (optional package)


  • centrifugal fan-cooling permanent magnet motors adopt variable frequency control technology. They can save about 50% of the energy. Rotation speed of the cooling fan can be adjusted according to gas emission temperature, so as to reduce power consumption. Stable temperature of the overall system can improve durability of parts. In addition, variable frequency cooling fan can lower the noise.
  • Centrifugal cooling fans are characterized by high efficiency, low noise, balanced pressure curve and other outstanding performances.

Reduce energy costs


  • When the energy accounts for above 70% of the life cycle cost (LCC) of compressor, the energy consumption optimization becomes essential. In fact, the power consumption for the production of compressed air accounts for over 40% of the total power consumption of the plant, so the energy consumption optimization can even determine its success. Using the permanent-magnetism frequency-conversion technology of Dresdnerlan, we can provide partners for your cost saving. WZS series of products can truly reflect the demand for compressed air, making substantial energy saving become a reality
  • Traditional compressors are operated between two set pressure points using the control methods of "full load and no load". The compressor turns into no load mode when the pressure reaches the maximum. When the air demand is medium or low, the no-load power will be consumed excessively, which will result in large amount of waste.
  • Because no unnecessary power consumption will be generated, the energy cost reduced by the permanent-magnetism frequency-conversion can be up to 35% or more. The life cycle cost (LCC) of the compressor can be reduced by an average of 22%. In a word, compared with the compressor with invariable rotate speed, Wan Beardsley compressor can recover the extra cost within 1 or 2 years.

Energy Saving


  • Traditional compressors (standard machine) usually use ON / OFF or proportional regulation system, which adjusts the opening amount of the air inlet of compressor. The adjustment method can also meet the actual requirements of the actual gas consumption, but the revolving speed of the compressor maintains at the rated speed in the entire adjustment process, the frictional work and cooling fluid agitation work will not be reduced, so although the gas consumption is lowered, the actual power consumption is not limited substantially. The variable frequency regulation can make the actual power consumption of the variable frequency compressor decline in the same proportion, and the energy is effectively used into the air compression.
  • In the market environment with fierce competition, it is an important matter as to whether the cost can be reduced. With the use of PM frequency conversion technology, you can save energy, thereby decreasing electricity expenditure sharply. It adjusts the compressor production capacity automatically according

Steady Pressure


It tracks system gas volume changes automatically, and adjusts the revolving speed of compressor accurately with the use of PID (proportional, differential, integral), to keep the system pressure stable.
