Product Name: Lkvf90-8-II 90kw Energy Saving Two Stage Compression Permanent Magnet Variable Frequency Screw Air Compressor Model NO.: LKVF90-8-II Type: Twin-Screw Compressor Installation Type: Stationary Type Structure Type: Closed Type Cylinder Position: Vertical Power Source: AC Power Cooling System: Air Cooling Lubrication Style: Oil-free Exhaust Pressure: 0.6-0.8MPa Exhaust Flow-Rate: 19.67-22.78m3/Min Motor Power Range: 90kw Transport Package: Wood Pallets Specification: 3530*2280*2270mm Origin: China HS Code: 8414809090 Product Description Our company specialize in making various kinds of compressors, such as:Diaphragm compressor,Piston compressors, Air compressors, etc. Can be customized according to your parameters.90kw permanent magnet variable frequency two-stage compression screw air compressor:1. Improve operation efficiency. It can achieve high efficiency and energy saving in all working conditions from low speed to high speed (motor speed from 1200-7600 R / min), from low pressure to high pressure (6.2-10 bar).2. Excellent energy efficiency. It can meet various pressure demands of customers and can choose freely from 19.67 cubic meters to 22.78 cubic meters. Under different pressure and displacement conditions, the measured specific power basically meets the national level 1 energy efficiency standard, and the unit can maintain stable high efficiency and power factor.3. Highly integrated control. The control system of frequency converter and screw air compressor is integrated into one, with high degree of automation, accelerated control speed and improved control accuracy.4. Safe and balanced operation, low noise. The rotating speed can double that of the existing domestic products, and the operating noise is about 65dB. Compared with the current domestic market of low-speed permanent magnet frequency conversion.Features of high speed permanent magnet variable frequency screw machine:1. The range of speed regulation is wider, the regulation accuracy is higher, the range of gas supply pressure is wider, and the energy efficiency is higher.2. The patent design of weak magnetic control, pressure control and simple and stable open-loop control of permanent magnet motor can adapt to a variety of adverse conditions and make the system more stable.3. Smaller volume, lighter weight, less noise and high efficiency (less leakage of high-speed rotor).4. The motor and the screw host are coaxial, so the efficiency is higher.5. It is the realization of screw main engine, synchronous motor, permanent magnet control electric control synchronous design in domestic screw compressor industry, and the realization of perfect coordination and other advantages.The follwing is technical parameters of two-stage screw air compressor:
