Briefly describe the process and trend of localization of screw air compressors
With the development of society, the advancement of technology, and the improvement of living standards, the devices we use around us are also quietly changing. From the popularity of micro-oil air compressors, to now more and more related to people's livelihood or important industries, oil lubricated air compressors are gradually replaced, which is also the trend of the times, JOY Machinery ( The editor of Shanghai) Co., Ltd. will introduce to you as follows:
The rapid development and progress of screw air compressors in China in the past ten years is not only an important aspect and an important part of the rapid development of China's equipment manufacturing industry, but also an important step in basic research, unit manufacturing, use and maintenance. An important symbol of entering the world's advanced level. With the development of screw air compressors in the past two decades, the process of localization can be considered as the following process:
1. The complete import stage of the whole machine. In the meantime, although there are air compressor factories developing important components, the equipment is outdated, the machine performance is poor, and there is no condition for large-scale production. International multinational companies entered China and monopolized the Chinese screw machine market. At the same time, the domestic technical standards, basic theories, personnel training and other work are starting at this stage.
2. Import stage of important components. Enter the Chinese market represented by OEM products from GHH, ROTORCOMP, TAMROTOR and other OEMs. In particular, the German GHH company, which only produces main engines, entered the Chinese market with its CF series of high-performance main engines, which has fully stimulated the enthusiasm of the Chinese people for screw air compressors. In just 2 to 3 years, screw air compressors have been fully recognized by the industry. , the monopoly of international multinational corporations is gone forever. Many domestic screw air compressor factories have established a solid competitive foundation.
3. During the same period, important accessories from HOERBIGER, VMC, AIRCON, DANFOSS, PARKER, LEKLLI and Baode entered China.
4. The localization stage of general components. In this stage, apart from the obvious start of the development of the main engine, other components can already be produced in China.
5. The localization stage of important components. This stage is represented by the air end, and also includes intake valves, controllers, sensors, etc.
6. Domestic air compressors and domestic brands are rising rapidly.
