PRODUCT DETAILS

 

Leading constant pressure control

 

AVF permanent magnet variable frequency screw compressors can sustain the air supply at the pressure of 0.1 bar in any loading conditions. In case of larger demands for air supply, the compressor can increase its rotation speed without changing the pressure to guarantee the air volume. In case of lower demands for air supply, the compressor can reduce its rotation speed without changing the pressure to meet such demands. In case of no demands for air supply, the compressor will switch to sleep mode to save energy. When actual pressure achieves the wakening standard, the compressor will immediately start up with rapid response of frequency converters even in sleep mode.

 

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

 

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.

 

Start without stamping

 

  • The variable frequency starting method reduces the impact of the start of the compressor on the power grid and mechanical parts greatly, thus extending the life of the machine.
  • Eliminate invalid transitional period from full-load power to no-load power
  • Avoid excessive no-load power consumption
  • Maintain the net pressure section
  • Reduce the overall average operating pressure
  • System pressure is low, making the system leak declined to a minimum
  • It accelerates with the use of soft-start motor gradually, to improve flexibility, thus avoiding the surge

Similarly, for two models with above rated power 37kw, when load rate is only 605, input power of power-frequency model under ordinary air inflow throttling control is 39.2kw; while shaft power of permanent magnetic power-frequency motor is 23.6kw with electricity saving ratio being 37.5%. If we calculate according to 40,000 operating hours per year, annual electric charge of ordinary asynchronous power-frequency model is RMB 107,200, however, annual electric charge of permanent magnetic synchronous servo model is RMB 65,800, saving RMB 41,400 in each year.

 

Difference of servo permanent magnetic variable-frequency technology and non-variable frequency technology in energy conservation

 

Non variable-frequency unit regulates demand for air discharqe with modulatinq capacity valve, while servo permanent magnetic variable-frequency unit regulates demand for air discharge in way of motor frequency conversion, and comparison of energy conservation between the two is as following:
