Energy Efficient Industrial Screw Compressor With Direct Drive Silent​

New generation of highly efficient imported host machine

• Advanced 8d Energy saved spiral tooth-type technology
• New-type 5:6 asymmetrical rotator tooth type
• Drawing uses leitz high-precision CMM measuring machine
• 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

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.

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.

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.
