Explosion-proof Roots blower project

Case 13.05.2026

North China Refinery Project: Explosion-proof Roots blowers are adopted to realize simultaneous positive and negative pressure conveying of petroleum gas mixture.

Project Pain Points

Substandard waste gas discharge; high safety risks in petroleum gas mixture transmission; required coordinated positive and negative pressure operation. Waste gas is sucked under negative pressure and delivered to water treatment system under positive pressure with complex and strict operating parameters.

Core Equipment Requirements

Absolute safety reliability

Zero air leakage of blower

Stable and continuous operation

Effective prevention of equipment overheating

Selected Model

LSR series Roots blower, bronze body, combined mechanical and nitrogen sealing structure, equipped with circulating water cooling system.

Project Outcome

All technical difficulties are fully solved. The solution gains client recognition, and the whole system is safely and steadily put into operation.
