- Advanced Vacuum Solution for Steel VD/VOD Process
New Installation of Vacuum Pumping System for Steel VD/VOD Process
N company (China)
Delivered in 2023
3-Stage Modular System : Dry Screw Vacuum Pump (SSS3000) + 2-Stage Roots Booster
- VFD (Inverter) Controlled Motors
- Advanced Filtration: Bag Type Filter + 30μm Suction Filter
- Heat Exchanger (specifically for VOD process)
N Company faced significant operational hurdles with their existing vacuum system due to the harsh nature of VD/VOD processes. The primary pain points included:
Persistent fine dust bypasses conventional filters, leading to pump wear.
Moisture from refractory materials creates acidic condensate (pH 3), causing severe durability problems.
24/7 continuous operation meant that any pump failure resulted in immediate and costly production downtime.
Difficulties in optimizing energy consumption during repetitive pump-down cycles.
We proposed a customized, modular 3-stage vacuum system designed to withstand dust and acidic environments while maximizing energy efficiency through VFD logic.
1st Stage Roots : 44,000–47,000 m³/h
2nd Stage Roots : 12,000 m³/h
3rd Stage Dry Screw : 3,000 m³/h
Total suction capacity reaches 36,000–40,000 m³/h at 0.67 mbar, perfectly matching low-pressure VD/VOD requirements (0.4–0.8 hPa).
Implementation of a 30μm suction filter post-bag filter and an Inlet Purge system to protect internal pump components from residue.
VFD control logic tailored to the client's specific VD/VOD cycles for optimized operation.
The transition to our dry vacuum solution delivered measurable improvements across the board:
Unlike traditional steam ejectors, our system offers instant startup, enhancing overall productivity and process consistency.
VFD control allows for reduced speed operation during standby modes between batches, significantly cutting energy costs.
Shifted from reactive repairs to predictive maintenance, minimizing unplanned downtime and eliminating the need for high-pressure steam or fuel.
