An Engineering Project of a Hydropower Bureau in Chongqing

Our client, a tier-one Hydropower Construction Bureau in Chongqing, faced significant challenges during the construction of a large pumped-storage power station. The site featured high-altitude tunnels with excessive groundwater seepage and summer temperatures exceeding 38°C with 90% relative humidity. Their previous compressors frequently shut down due to "emulsified lubricant" and overheating, causing costly project delays and tool breakage. The procurement manager urgently sought a supplier capable of customizing solutions rather than selling standard off-the-shelf products.

Leveraging 21 years of manufacturing expertise, we deployed our flagship heavy-duty screw air compressor, equipped with an oversized aftercooler and a specialized high-temperature-resistant synthetic lubricant. We added an automatic water drainage system at the air receiver and installed an extra-stage air filtration module to handle the silica dust typical of Chongqing's granite strata. Furthermore, our engineers reprogrammed the PLC controller to prioritize "constant pressure" over "energy saving" during peak load, ensuring stable 8.5 bar pressure even with fluctuating air demand.

As an industry standard-setter and exporter to over 100 countries, we provided full documentation, including CE certification, performance curves, and a bilingual operation manual. This project transformed our relationship from vendor to long-term technical partner, with repeat orders for three subsequent diversion tunnels. We proved that for mega-infrastructure, choosing a reliable compressor is not an expense—it's an investment in schedule certainty.
