Previously, our company undertook the transformation of a petrochemical company Corblin imported diaphragm compressor localization retrofit and returned the unit to return to the production site.Recently, the project ushered in a period of good news: the customer specifically sent feedback, indicating that the equipment was stable, safe and reliable, and did not cause any fluctuations in the production line throughout the whole process, and fully affirmed the achievements of this technological transformation.This simple and powerful affirmation is not only the highest praise for the technical strength of the project team, but also marks that this French "veteran" who has served for 36 years has successfully crossed the bottleneck of the life cycle and continues to escort the safe production of the enterprise with a new attitude.
This Corblin diaphragm compressor, produced in France in 1990, is the company's "meritorious veteran", but its 36 years of super-long service have also made it "sick". Based on the pain points of on-site working conditions, Zhongding Hengsheng has tailored a full set of domestic upgrading and transformation plans to carry out systematic technology optimization.
Dual improvement of performance and longevity

The operating efficiency of the unit has been significantly improved, and the service life of the diaphragm has been greatly extended, which directly reduces the consumption frequency of the core wearing parts.

Smooth and Quiet Operation

The vibration value of the equipment has dropped sharply, and the whole machine has made a leap in stable operation, providing a stable support for the precision process.

Visualization and control enhancements

The real-time online display of oil drainage pressure fills the monitoring blind spot of the original machine; the centralized layout of the pressure gauge makes the parameter reading clear at a glance, and the controllability of equipment adjustment has increased comprehensively.

Compliance and Safety

All technical indicators are in line with the current national standard specifications, building a solid line of defense for the long-term safe and stable operation of the equipment.

Significant reduction in O&M costs

Through localized replacement and performance optimization, the difficulty of spare parts procurement and daily maintenance costs are effectively reduced.

Improved Ease of Operation

The user-friendly design improves the on-site operation experience, reduces the labor intensity of employees, and comprehensively optimizes the overall operating performance of the unit.



Customer satisfaction is the best form of acceptance. From the "foreign equipment" that drifted across the sea 36 years ago to the "reassuring equipment" that is now adapted to local production needs, this localization upgrade has not only eliminated hidden dangers for enterprises, but also maintained production continuity, and has accumulated valuable replicable experience in upgrading imported equipment of similar overdue service.

In the future, Zhongding Hengsheng Service Center will continue to revitalize overdue service equipment with localized technology, use precision retrofit to ensure continuous production of enterprises, so that more old equipment will be rejuvenated, and use hard core technology to help enterprises reduce costs and increase efficiency and stabilize production.
