Industrial Screw Compressor DETAILS

  • The rotor adopts advanced high-efficiency molded lines, which ensures stability and high-efficiency;
  • It adopts two-stage independent compression, same pressure ratio, low speed design, thus enhancing more than 15% of air volume under the same power;
  • Guarantee of low compression ratio at every state, smaller host engine leakage, higher volume efficiency;
  • It adopts oil mist spray cooling at stage intervals, so as to make the entire compression process close to isothermal compression, thus improving the compression adiabatic efficiency;
  • The two segment rotors are directly driven by bevel wheel, so that each rotor obtain the best line speed, and the compression transfer efficiency is the highest;


Highly efficient and energy-saving permanent magnetic motor


The airend is highly efficient and energy-saving permanent magnetic motor with protection level of IP55 which is elaborately selected according to requirement of application of air compressor, it reaches national grade-1 energy efficiency standard, both torque and load can meet special design standard so as to achieve optimization of motor efficiency and power factors under loading conditions. This optimized coefficient has about 5%-8% advantages when compared with efficiency of other motors.


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.


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:
