Previously, the localization retrofit of a Corblin imported diaphragm compressor undertaken by our company for a petrochemical client was completed, and the unit has returned to the production site. Recently, the project achieved a significant milestone: the client provided specific feedback, stating that the equipment operates stably and safely, causing no fluctuations to the production line throughout the process, and fully affirming the results of this technical transformation. This simple yet powerful affirmation is not only the highest commendation for the project team's technical strength but also marks the successful overcoming of the lifecycle bottleneck by this 36-year-old French "veteran," which now continues to safeguard the enterprise's safe production with a renewed posture.

This Corblin diaphragm compressor, manufactured in France in 1990, can be regarded as the company's "meritorious veteran." However, its 36 years of extended service have left it plagued with issues. Addressing the pain points of the on-site operating conditions, Zhongding Hengsheng Gas Equipment (Wuhu) Co., Ltd. customized a comprehensive localization upgrade plan and carried out systematic technical optimization.

Dual Improvement in Efficiency and Lifespan

The operational efficiency of the unit has significantly improved, and the service life of the diaphragms has been greatly extended, directly reducing the replacement frequency of core wearable parts.

Stable and Quiet Operation

Equipment vibration values have decreased significantly, representing a leap in the stability of the entire machine's operation, providing stable support for precision processes.

Enhanced Visibility and Controllability

Real-time online display of oil discharge pressure fills the monitoring blind spots of the original machine; the centralized layout of pressure gauges makes parameter reading clear at a glance, comprehensively increasing the controllability of equipment adjustment.

Compliance and Safety Assurance

All technical indicators fully comply with current national standards, building a strong defense line for the long-term safe and stable operation of the equipment.

Significant Reduction in O&M Costs

Through localization substitution and performance optimization, the difficulty of procuring spare parts and the cost of daily inspection and maintenance have been effectively reduced.

Optimized Operational Convenience

Human-centric design enhances the on-site operational experience, reduces employee labor intensity, and comprehensively optimizes the overall operational performance of the unit.
