Screw Air Compressor DETAILS

 

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.

 

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.

 

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).
