Product Description

Screw Vacuum Pump is vacuum Performance Synergy: Precisely Matching with High-Power Screw Compressors to Ensure Production Efficiency

The core requirement for foreign customers purchasing 5.5kW dry screw vacuum pumps is to ensure they form an efficient "power-vacuum" synergy with 30hp, 40hp, and 50hp screw compressors, avoiding compressor overload or insufficient vacuum efficiency due to performance mismatch. This dimension focuses on pumping speed compatibility, vacuum range, and pressure stability.

1. Precise Matching of Pumping Speed and Compressor Power

High-power screw compressors of varying horsepower meet different production scales and require matching vacuum pumps with matching pumping speeds. For 30-horsepower screw air compressors (commonly used in medium-sized lithium battery material drying and automotive parts pre-painting applications), a foreign customer requested a 5.5kW Dry Screw Vacuum Pump with a stable rated pumping speed of 25-35m³/h and a pumping speed adjustment range of 10%-100%. This speed can be flexibly adjusted based on the 30-horsepower compressor's exhaust volume (approximately 3.8-4.5m³/min). This ensures a uniform vacuum level within the drying chamber, avoiding extended drying cycles due to insufficient pumping speed or excessive compressor load due to excessive pumping speed.

For medium- to large-scale applications using 40-horsepower screw air compressors (such as chemical intermediate distillation and photovoltaic module lamination), customers are particularly concerned about the Vacuum Pump's variable load pumping speed responsiveness. The Screw Dry Vacuum Pump was required to receive compressor load signals via the PLC system. When a 40-horsepower air compressor's load increases from 60% to 100% (approximately 5.0-5.8 m³/min) due to production demand, the vacuum pump's pumping speed could increase from 15 m³/h to 38 m³/h within 30 seconds, synchronizing with the compressor's compressed air output. This ensured a stable vacuum level of 5-10 Pa during the distillation process, preventing product purity degradation due to vacuum fluctuations.

For high-load applications driven by 50-horsepower screw air compressors (such as large-scale pharmaceutical freeze-drying production lines and semiconductor wafer coating), customers had stringent requirements for high vacuum pumping speed stability. The vacuum pump needs to be able to stably achieve a high vacuum degree below 1Pa at a power of 5.5kW, and maintain a pumping speed of ≥28m³/h within this vacuum range. It should be compatible with the high flow output of a 50-horsepower air compressor (exhaust volume of approximately 6.2-7.0m³/min) to ensure rapid removal of moisture from the freeze-drying chamber and no impurity interference during wafer coating, while also avoiding production batch scrapping due to fluctuations in pumping speed.
