Product Description
This is a high-power industrial core power unit. Its key features are:
• Power frequency constant speed: The motor is directly connected to the industrial power grid (50Hz) and operates at a constant speed, adjusting gas volume through a "load-unload" cycle.
• Single-stage compression: Air is compressed to the target pressure in a single operation in a pair of screw rotors.
• High power range: 90-132kW (approximately 125HP to 175HP) is its core power range, enabling significant gas production.
Features and Advantages
1. Rugged and Durable Structure: The technology is extremely mature, the design is simple, and it can operate continuously under heavy loads for 24 hours under rated conditions, with high reliability.
2. Low Initial Investment Cost: Compared with permanent magnet variable frequency drives of the same power, its purchase and maintenance costs are more competitive.
3. Easy Maintenance: The standard structure and widely compatible components require relatively low technical skills for maintenance personnel.
4. Stable High-Efficiency Range: Its efficiency remains stable under full-load, continuous operation.
Main Disadvantages (Compared to VFDs)
• High Energy Consumption: Idle energy consumption is significant during "unloaded" operation (up to 30%-40% of full load power), and energy efficiency is extremely low at partial load, resulting in high overall electricity costs.
• Significant Starting Shock: The inrush current from direct power frequency starting is very high, placing severe strain on both the power grid and electrical components.
• Pressure Fluctuation: The pressure fluctuates between the set upper and lower limits, making the supply pressure less stable than that of a VFD, affecting the accuracy of gas-consuming equipment.
Main Application Scenarios
Suitable for large-scale, continuous production plants with very stable air volume demand close to the rated displacement of the air compressor, such as:
• Large-scale heavy industrial manufacturing: steel, shipbuilding, and heavy machinery processing plants.
• Chemical and petrochemical industries: instrument air and process air for large production lines.
• Large textile mills: providing a stable air source for equipment such as air jet looms.
• Centralized air supply stations: serving as the "base load" machine for multiple machines within the station, operating at full capacity year-round.
