High Reliable Two-Stage 0.7MPa Stationary Water Cooled Injected Screw Air Compressor
Introducing our cutting-edge two-stage screw air compressor, designed for unparalleled performance and efficiency in air compression processes. Utilizing innovative technology, this compressor ensures optimal efficiency by reducing real-world inefficiencies such as coupling power loss, bearing friction, and cooling liquid viscosity. By minimizing the compression ratio at each stage, this compressor significantly lowers total power requirements compared to single-stage compression.
Product Description
Our two-stage screw air compressor features a dual-stage rotary screw mechanism, with each stage possessing an active and a passive screw. The active screw drives the passive screw via an external power device, ensuring seamless operation. With the first stage utilizing a low-pressure rate screw group and the second stage employing a high-pressure rate screw group, this compressor compresses gas through distinct phases of suction, pressurization, and exhaust.
Working Principle
The process begins with the low-pressure rate screw group compressing the gas, gradually transferring it to the second stage under high-speed rotation. In the second stage, the gas undergoes compression at elevated temperatures and pressures before being expelled through the exhaust valve, completing the compression cycle. The innovative design enhances efficiency and reduces power consumption.
Unique Features
Featuring a state-of-the-art permanent magnet motor and an integrated frequency converter, this compressor offers superior efficiency and energy-saving benefits. The two-stage compression air end and internal spray curtain cooling system ensure exceptional performance, while minimized internal leakage and noise reduction further enhance its operational capabilities.
