In recent years, the state has given certain support to the technology introduction, technological transformation, scientific research and development of the hydraulic and pneumatic seal industry, which has promoted the rapid development of the industry. China's agriculture, water conservancy, energy, transportation and other industries develop rapidly, so a lot of machinery and equipment are needed to meet the needs of their development. With the increasing level of industrialization and automation, these equipment need to be equipped with a large number of high-performance and highly reliable hydraulic pneumatic and sealing components.
Overall, the formation of state-owned enterprises, private enterprises, three-legged tripod situation, the output value is basically one-third. State-owned enterprises are stepping up reform efforts; A large number of private enterprises have risen rapidly; A large number of foreign investment has entered, and the world's major famous companies are basically carrying out joint ventures, sole proprietorship, sales and other businesses in China, showing the trend of the transfer of manufacturing to China. In terms of technical level, the leading products of state-owned enterprises are mainly introduced and independently developed in the 1980s, basically at the international mid-range level; Most of the private enterprises are mainly middle and low grade products, but the accumulation of funds is rapid, the use of domestic existing technology, gathered experienced talents, rapid progress in technical level, and its product quality, variety and service continue to improve in the competition; Foreign-funded enterprises with medium and high-end products as the main technical level of foreign countries, for domestic joint ventures, wholly-owned enterprises need to provide high-end host and key projects supporting.
With the rapid development of China's economy, all kinds of mechanical equipment using hydraulic, pneumatic transmission and control is increasing, and the technical requirements for seals are increasing. China's fluid power product market developed rapidly, in addition to the United States, Europe, Japan, ranked first in the developing countries. China's imports are also increasing, and the market has great potential for development.
With the improvement of industrialization and automation level, mechanical equipment needs to support a large number of high-performance and high-reliability hydraulic pneumatics and seals. In addition to the construction of the Three Gorges of the Yangtze River, the South-to-North Water Diversion project, the west-to-east gas transmission project, the west-to-east electricity transmission project and the Qinghai-Tibet Railway, there are also a large number of major projects such as large-scale coal mines, oil fields, open-pit iron mines, power stations, airports, ports, high-speed railways and high-grade highways, as well as a large number of urban and residential construction projects. To this end, the increasing workload of earthwork loading and unloading, coupled with the development of modern logistics, as well as the application of new processes, new technologies and new materials, will make the domestic demand for construction machinery maintain a long-term growth trend. In short, the above products need a large number of high pressure piston pumps, high pressure gear pumps, large torque motors, wheel motors, multi-way valves, oil cylinders, pipe fittings, pipeline assembly and oil filters, etc., for construction machinery supporting, maintenance of hydraulic and seal markets will face a new era of great development. Among them, construction machinery is the user of hydraulic products, accounting for 42.3% of industry sales, and the proportion will expand in the future, so the development trend of construction machinery is crucial. In addition, every year for domestic enterprises to produce excavators, road machinery, cement mixing trucks and other supporting imported hydraulic parts, about 150 million US dollars. In short, the market for construction machinery supporting, maintenance of hydraulic and seals will face a new era of development.
