odf screw air compressor features a screw rotor ( host ) imported from germany , the use of third-generation asymmetric rotor tooth is 5:6 aspect ratio reasonable choice , its tangential speed of the rotor is only 30-36m / s, well below the generally tangential speed compressor 60ms keep 0.003inch gap between the rotor and never wear a small gap between teeth , so reflux smaller loss than 4:6 tooth to improve efficiency 10-12 % , saving electricity 20% , the swedish skf bearings , greatly extending the life of the host.
1, the switch : 3-way switch input , 5-way relay switch output ;
2 , analog : a road pt100 temperature input , 1 channel 4 ~ 20ma transmitter input , two sets of three-phase current inputs ( supporting ct);
3, the controller working power : ac20v 40av;
4 , the display range
a), oil temperature : -20 ~ 150 ℃;.
b), temperature : -20 ~ 150 ℃;.
c), running time : 0 to 999,999 hours .
d), the current display range : 0 ~ 999.9a.
e), pressure : 0 ~ 1.60mpa.
5 , phase sequence protection : when the fault protection detects phase motor to save guard ;
6 , motor protection : the controller for the main motor and fan motors are having stall, short circuit, phase imbalance , basic overload protection function ;
7 , temperature protection : when the actual temperature is greater than the set temperature detected movement ;
