Reasonable Structure Industrial Screw Compressor Asymmetrical Magnetic Circuit Design
Industrial Screw Compressor ADVANTAGES/FEATURES
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:

FAQ:
1. Before quoting, what should users offer?
1). Discharge pressure (Bar, Mpa or Psi)
2). Air discharge/Air flow/Air capacity (m3/min or CFM)
3). Power supply (220/380V, 50/60Hz, 3Phase)
2. If I don't know the pressure and air flow, what should I do?
1). Take the picture of nameplate, we will advise the suitable air
compressor to you.
2).T ell us what industry you are, we can advise the suitable one
(so as to air tank / air dryer / air filters).
