Screw Compressor China

Introduction to China's screw air compressor technology
1. Permanent magnet frequency conversion technology breakthrough
Using permanent magnet synchronous motor and intelligent frequency conversion control system, the motor efficiency is 12%-15% higher than that of traditional asynchronous motor, and the power factor is above 0.95. The air volume is accurately matched by adjusting the speed in real time, and the maximum energy saving can reach 55%. The soft start technology reduces the starting current to 1/3 of the traditional model.

2. Precision manufacturing of screw rotors
Rotor design: Apply asymmetric profile optimization and CFD simulation technology, volumetric efficiency reaches 98%, and single-stage compression ratio is increased to 15:1


Gap control: CNC machining accuracy reaches micron level, radial/axial gap optimization reduces gas leakage, and extends bearing life to 20,000 hours

3. Intelligent system control
8-inch touch screen and remote monitoring system, real-time monitoring of 12 operating parameters, preset 32 ​​fault code warnings, on-demand maintenance through mobile phone APP, maintenance cost reduced by about 1/3

4. Environmentally friendly
100% oil-free lubrication technology: Class 0 certified models have an exhaust oil content of <0.01ppm, which meets the requirements of food processing, electronic manufacturing, chemical industry and other industries with high requirements for compressed air purity.


Waste heat recovery: 80-100℃ exhaust heat is converted into hot water, and the recovery rate can reach 3/4 of the input power

Multiple noise reduction technologies: noise is as low as 62 decibels

Future trends of China's screw air compressor technology
In 2024, China's screw air compressor production and sales will increase by 5.6% year-on-year. Permanent magnet frequency conversion and Internet of Things technologies will promote domestic substitution in the high-end market.
