10kV High-Voltage 315kW Two-Stage Screw Compressor

10kV High-Voltage 315kW Two-Stage Screw Compressor

TCO & ROI: The Financial Logic of High-Voltage 315kW Systems

For high-capacity industrial systems operating 315kW (430 HP) plants, low-voltage electricity (380V/440V) presents major operational hurdles, including immense line losses, massive cable cross-sections, and heavy starting currents that destabilize local plant grids. The Jufeng 10kV high-voltage two-stage screw compressor addresses these issues at the structural level. By shifting the native electrical draw to 10,000 Volts, currents drop drastically, and heat dissipation losses plummet, generating substantial long-term electricity savings.

Total Cost of Ownership (TCO) Fact: Operating a standard 315kW compressor 24/7 translates to massive annual energy expenditures. Jufeng's combined 10kV high-voltage integration and 2-stage air end drop specific power consumption to an Industry-Leading low, achieving capital payback on technology differentials within 14 to 18 months.

Deep Engineering Architecture Features

1. Advanced Isothermal Two-Stage Rotary Air End

Our dual-rotor design does not force air through a single, harsh pressure curve. Instead, air is compressed progressively through consecutive primary and secondary stages:

• Inter-Stage Cooling: Precision inter-stage oil mist injection cools the air stream between stages, shrinking the specific volume of the air before it reaches the secondary chamber.
• Minimized Rotor Slip: Dropping the internal pressure ratio across each individual rotor means internal air bypass and blow-by leakage are completely eliminated, preserving strict volumetric delivery.

2. Direct 10,000V Grid System Performance

• Premium Insulation Security: Built with severe-duty high-voltage motors featuring vacuum pressure impregnation (VPI) epoxy systems and PTC thermistors to guarantee thermal integrity under sustained baseload duties.
• Streamlined Infrastructure: Eliminates large step-down distribution setups, simplifying substation space footprints and lowering local electrical design costs.

3. Heavy-Duty Mechanical Integration

• Coaxial Direct Shaft Coupling: Employs zero-slip flexible couplings to deliver a true 1:1 mechanical transfer efficiency from motor to rotors, avoiding all energy losses from internal gear or V-belt setups.
• High-Capacity Fluid Separation: Triple-stage mechanical and centrifugal fluid separation lowers residual lubricant downstream to ≤2 ppm, shielding valuable pneumatic tools and valves.
