China's first auto chassis automatic detection equipment in Luoyang off the assembly line

October 07, 2025

**Zhengzhou, October 22 (Reporter Li Lijing) –** In a major breakthrough for China's automotive industry, the first domestically developed automatic detection system for car chassis components was successfully launched by Luoyang Libang Measurement and Control Equipment Co., Ltd. in the Luoyang High-tech Zone, Henan Province, on October 21. This innovative equipment marks a significant milestone, as it ends China’s long-term reliance on imported technology for the automated testing of critical chassis parts. The system, which costs only one-sixth of similar imported models, is expected to bring substantial cost savings and technological independence to the domestic auto industry. Prior to this development, the quality inspection of chassis components such as brake discs, gearboxes, and axles had been entirely dependent on foreign suppliers. Major Chinese automakers, including FAW, Second Automobile, SAIC, and Hafei, had previously sought solutions from overseas manufacturers. In response to this demand, Luoyang Libang Measurement and Control Equipment Co., Ltd. initiated its independent research and development project in 2006. After more than a year of dedicated effort, the company successfully completed the project, delivering a high-precision, reliable, and cost-effective solution that meets international standards. This achievement not only strengthens China's position in the global automotive supply chain but also highlights the growing capabilities of domestic manufacturers in advanced manufacturing technologies. Industry experts believe that this breakthrough will drive further innovation and reduce dependency on foreign technology in the years to come.

Plate Heat Exchanger T Series

Plate Heat Exchangers (PHEs) are highly efficient devices used for heat transfer between two fluids. The U Series of plate heat exchangers is a specific design known for its compactness, flexibility, and high thermal efficiency. Below is a detailed classification and introduction to the U Series Plate Heat Exchangers:

1. Based on Design Features

  • Gasketed Plate Heat Exchangers:

    • Uses gaskets to seal plates and create flow channels.

    • Easy to disassemble for cleaning and maintenance.

    • Suitable for applications with moderate temperature and pressure.

  • Brazed Plate Heat Exchangers:

    • Plates are brazed together using copper or nickel.

    • Compact and leak-proof design.

    • Ideal for high-pressure and high-temperature applications.

  • Welded Plate Heat Exchangers:

    • Plates are welded together for a robust construction.

    • Suitable for corrosive or high-temperature fluids.

    • Commonly used in industrial applications.

      2. Based on Flow Configuration

      • Single-Pass U Series:

        • Fluids pass through the heat exchanger once.

        • Simple design with lower pressure drop.

      • Multi-Pass U Series:

        • Fluids pass through the heat exchanger multiple times.

        • Increases heat transfer efficiency but may result in higher pressure drop.

          3. Based on Application

          • HVAC U Series:

            • Used in heating, ventilation, and air conditioning systems.

            • Efficient for heat recovery, chillers, and heat pumps.

          • Industrial U Series:

            • Designed for industrial processes such as chemical, food, and pharmaceutical industries.

            • Handles high temperatures, pressures, and corrosive fluids.

          • Refrigeration U Series:

            • Used in refrigeration systems for evaporators or condensers.

            • Compact and efficient for low-temperature applications.

          • District Energy U Series:

            • Connects to district heating or cooling networks.

            • High-capacity and energy-efficient.

              4. Based on Plate Material

              • Stainless Steel Plates:

                • Corrosion-resistant and durable.

                • Suitable for most applications, including food and beverage industries.

              • Titanium Plates:

                • Highly resistant to corrosion, especially in seawater or chloride environments.

                • Used in marine or chemical industries.

              • Nickel Plates:

                • Resistant to high temperatures and corrosive fluids.

                • Ideal for chemical processing or oil and gas industries.

                  5. Based on Gasket Material

                  • Nitrile (NBR) Gaskets:

                    • Suitable for water, oils, and low-temperature applications.

                  • EPDM Gaskets:

                    • Resistant to high temperatures and steam.

                    • Commonly used in HVAC and heating applications.

                  • Viton (FKM) Gaskets:

                    • Resistant to aggressive chemicals and high temperatures.

                    • Used in chemical or industrial applications.
