Brief Report on China's Screw Compressor Main Engine Market Research

一、Industry Overview

In recent years, with the transfer of the global compressor manufacturing industry, China has gradually evolved into a global compressor manufacturing base. The continuous growth of domestic and foreign market demand for compressor types and quantities has promoted the rise of my country’s compressor manufacturing industry. It has gradually reached a higher level of manufacturing in the industry. As an important part of the compressor market in my country, screw compressors have been gradually recognized by consumers in recent years due to their high efficiency, energy saving, stable performance and many other advantages, and have obtained rapid development.

As the core component of the screw compressor, the performance of the screw compressor has a decisive effect on the performance of the screw compressor. In the early stage of the industry's development, due to the low level of production technology and backward production equipment conditions, the production technology of the screw compressor mainframe was monopolized by international companies. Domestic screw compressor companies mainly imported from abroad to meet their production needs.Facing the huge market demand in China, international screw compressor manufacturers have been pouring into the country continuously, establishing screw compressor production bases in the country, and monopolizing the domestic screw compressor main engine market. Facing the monopoly of international advanced enterprises, driven by the increasing demand in the domestic market, some enterprises with financial strength and R&D capabilities began to shift their focus to independent research and development of screw compressor mainframes, and achieved obvious results, realizing screw compression The domestic development of the main engine of the compressor has established a solid competitive foundation for the rapid and independent development of the domestic screw compressor main engine industry.

With the continuous advancement of science and technology, the continuous application of various new technologies, new materials and new equipment in the manufacture of screw compressor mainframes has promoted the rapid development of the domestic screw compressor mainframe manufacturing industry. Now, the domestic screw compressor main engine industry is becoming more mature in terms of R&D and design level, or processing technology level, and is gradually developing in the direction of industrialization, scale and internationalization. In particular, the gradual promotion and application of high-precision CNC rotor processing and milling machines (grinding machines) and other advanced production equipment has made it easier to realize the processing of multiple profile lines. The development results of the main machine rotor profile lines have been continuously promoted and are being applied. Achieved a good market response.With the continuous improvement of the domestic screw compressor mainframe manufacturing technology, the domestic screw compressor mainframe has reached a higher accuracy and is gradually recognized by the market. At the same time, relying on the localized cost advantage, it has gradually broken the monopoly position of international enterprises in the domestic market. , And gradually compete with international brands in the high-end field.

At present, the domestic screw compressor main engine manufacturing industry has broken the monopoly of international companies, and has gradually formed a market structure in which foreign capital and joint ventures, Taiwan-funded enterprises, state-owned enterprises and private enterprises coexist. With the in-depth development of the industry, the domestic screw compressor mainframe will develop and grow faster through the continuous integration of industry advantage resources.

二、Market demand

As the core component of the screw compressor, the screw compressor main body is closely related to the market demand of the screw compressor, and it is growing steadily along with the increase in the market demand of the screw compressor. Screw compressors are indispensable strategic basic machinery in the national economy. Among the main models in the compressor market in my country, screw compressors have become the fastest-growing model in recent years due to their high efficiency and energy-saving performance advantages.At the same time, in the context of energy saving and emission reduction policies, traditional piston compressors, which are widely used, have been slowing down due to their high energy consumption, many vulnerable parts, inconvenient maintenance and many other defects, while screw compressors rely on their The wide range of capacity and operating conditions is gradually replacing some of the market areas of other traditional compressors. Therefore, in recent years, domestic screw compressors have developed rapidly, and their market applications have continued to expand, and products have gradually formed a series of products, which has brought huge market demand for screw compressor mainframe manufacturers.

According to the statistics of the Compressor Association, in 2011, the number of domestic screw compressors sold exceeded 169,000. According to the calculation of one screw compressor assembling one screw compressor main engine, in 2011, the domestic screw compressor main engine market Sales also exceeded 169,000 units, a year-on-year increase of 138,000 units in 2010, an increase of 22.5% and an increase of 61% over 2009.

Because screw compressors have obvious advantages such as energy saving, high efficiency, strong reliability, low noise, etc., they can better meet the development needs of the compressor market in the future. Its market demand will be far greater than the growth rate of traditional compressors, and even begin to gradually in many fields. Replace traditional compressors.Especially under the energy-saving development trend of "low carbon and environmental protection", the rapid development of domestic mining, metallurgy, electric power, electronics, machinery manufacturing, medicine, food, textile and light industry, petrochemical industry and other industries will also speed up the elimination of outdated technology and high-tech industries. Energy-consuming equipment promotes the upgrading of compressor equipment from low value-added to high value-added, thereby bringing further development opportunities for the screw compressor industry.According to the development trend of the screw compressor industry, the market demand for screw compressors will continue to grow steadily for a long period of time in the future. It is estimated that by 2015, the domestic market demand for screw compressors will exceed 351,000 units. Therefore, as the essential core component of screw compressors, the screw compressor mainframe will surely increase its market demand steadily along with the growth of screw compressors. By 2015, it will exceed the market demand of 351,000 units. The average annual growth rate will remain above 20%.
