WHAT RESULTS IN HIGH EFFICIENCY OF WAN BEARDSLEY AIR COMPRESSOR?

 

  • Variable frequency
  • Variable frequency air compressors can start steadily in the soft start mode, which could reduce power consumption at the start of the compressor.
  • Variable frequency air compressors set the minimum pressure of production equipment as the standard pressure. Rotation speed of variable frequency air compressors can fluctuate according to pressures of pipes, so as to guarantee constant pressure of pipes and reduce power consumption caused by pressure loss.
  • Power consumption of ordinary air compressors in idle load is only 45% of that in full load. Variable frequency air compressors are free from loading and unloading, so permanent magnet variable frequency air compressors consume no power at these two stages.
  • Improve operation efficiency

Efficiency is mainly decided by two parts of the air compressor. The first part is the host. It is easy for us to understand more air volume at cost of same power consumption means higher efficiency. The second part is electric motor. Permanent magnet motor and high efficient motor are common on current air compressors. Compared with ordinary electric motors, permanent magnet motors present higher efficient, higher power factor, and higher detent torch. Permanent magnet (synchronous) electric motors show the same detent torch as other synchronous electric motors. Without rotor windings, these permanent magnet motors show lower power consumption, because rotor excitation is unnecessary. However, permanent magnet motors need frequency converters which consume certain power. The test proves efficiency of low power permanent magnet motors remains higher than that of ordinary motors after adding frequency converters. We can use high efficient motors at high power stage to improve operation efficiency. On the other hand, characteristics of permanent magnet motors decide that they can maintain the same efficiency even at lower rotation speed. However, efficiency of ordinary motors declines with decreasing of rotation speed, showing a parabola curve

 

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.

 

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:
