It adopts a two-stage screw booster structure and is suitable for industrial applications with a pressure demand of 1.8MPa~4.0MPa. The medium and high pressure screw rotary air compressor features an imported integrated head for a compact structure, smooth operation, and low noise.
[pdf] Uses a dedicated variable frequency drive (VFD) for permanent magnet synchronous motors, enabling stepless speed regulation, constant pressure air supply, and soft start. This eliminates idle power consumption and enables intelligent air supply.
[pdf] Around 1891, the first submerged oil wells were drilled from platforms built on piles in the fresh waters of the in . The wells were developed by small local companies such as Bryson, Riley Oil, German-American and Banker's Oil. Around 1896, the first submerged oil wells in salt water were drilled in the porti.
