Conversion 22KW Rotary Screw Air Compressor 30hp Stationary Air Compressor

DHH Direct Driven Stationary Frequency Conversion Screw Air Compressor

 

How much energy PM can save?
Permanent magnet frequency compressor can save 25% 44% energy base on air capacity.
How to do it?
1.Remove full load to unload
2.DHH PM motor can save 6%-7% energy compare with other brand motor
3.DHH PM motor and compressor was designed with the one shaft
4. Avoid unload function
5.Protect pressure of pipe network< 0.01MPa
6.Reduce average working pressure
7.Reduce leakage from compressor system
8.Soft boot add balance for electric current,to avoid shock
9.PM compressor working pressure is from 4bar to 13bar,it can reduce the loss to the greatest extent.

 

Motor Main Features:
1.PM motor and compressor was designed with the one shaft, 100% transmission efficiency.
2 No motor bearing.,no trouble for maintenance.
3. Especially in the low-speed ,PM motor can still maintain a high
motor efficiency.
4.PM motor size is smal,and it's only about one third of an ordinary WWVF motor,which is easy to uninsal.
5.With the high-performance permanent magnet material,PM motor
don't lose magnetic even with the temperature of 120C. Its life will be more than 15 years.

  Advantages 1.Rotor
Rotors are asymmetric in profile, backed up by ball bearings and roller bearings. Operates at a low speed, thereby low in abrasion and maintenance expenses, air end is long service life. Helical gears can produce axial force to kill some acting force, which reduces the load of the bearing of air end.
2.Control panel
Intelligent microcomputer-based control technology can monitor and control in all aspects the complete machine following your instructions, remote control realizes unattended operation, and the user-friendly human-machine interface displays instructions and parameters in written form also, it can function to self diagnose faults, give warning and automatically regulate the capacity.
3.Oil filter
Rotary filters are applied to completely remove the impurities in the lubricating oil, easy to replace and free of oil impregnate.
4.Air filter
Original imported filter material,high efficiency three levels air separator, keep internal cleanliness of the system effectively.
5.Cooler
The cooler is located separately from the internal isolation of the chassis,so that the cooling fans would suck air with normal temperature from outside.Compared to cooling by using the air of 45~65°Cinside the chassis,the cooling fans could save over 30% energy when the temperature of the air outlet decreases 3~8°C.
6.Excellent quality of motors
Professional customized high efficiency permanent magnet motor,Compared to normal motors, Permanent magnet motor more excellent energy saving.protection grade:IP65.
