Variable operating conditions and discharge volume control of piston compressors
The variable operating conditions of piston compressors refer to the fact that their performance and efficiency change under different working conditions. Displacement adjustment is achieved by changing the piston’s movement frequency, stroke, or the way the valve opens. Common adjustment methods include: 1. **Speed regulation**: Changing the exhaust volume by adjusting the motor speed. 2. **Unloading regulation**: When the compressor is under excessive load, some cylinders can be unloaded to reduce the exhaust volume. 3. **Control valve**: A control valve is used to regulate the gas flow, thereby controlling the exhaust volume. These methods can effectively improve the adaptability and energy efficiency of compressors. .
