Race Against Time: Volm Vacuum Pumps Secure Production in 32°C Heatwave

1.Throughput Collapse in Heatwaves

• Designed weekly capacity: 30 tons | Actual summer 2022 output: 6 tons (only 20% utilization of capacity);

• Daily system restarts (3 times) took 2.5 hours each for pump-down;

• Order delay rate: 67% | Penalties: over ¥2 million.

2.Quality Crisis: 80× Moisture Excess

• Specification: ≤0.15% moisture | Summer reality: 12%;

• Purity loss increased rectification energy consumption by 42%;

• Return rate: 18% of sales | Complaints: +400% YoY.

3.Energy Drain & Hidden Costs

• System power: 82.5 kW (75kW liquid ring + 7.5kW Roots) | Efficiency: <50%;

• Contaminated cooling water required ¥86k/year wastewater treatment;

• Summer chiller power: extra ¥130k/quarter.

Root Cause: 

At 38°C, liquid ring working fluid (water) vapor pressure hit 6,610 Pa, creating 10 kPa Roots pump pressure differential that prevented startup.

System Upgrade: 

Screw-Roots vacuum systems eliminates temperature sensitivity through dry compression technology.
