Our country's seal technology improves the development of the industry

In recent years, the state has given certain support to the technical introduction, technological transformation, scientific research and development of the hydraulic and pneumatic seal industry, which has promoted the rapid development of the industry. my country's agriculture, water conservancy, energy, transportation and other industries have developed rapidly. For this reason, a large number of machinery and equipment are needed to meet their development needs. With the improvement of industrialization and automation, these equipment need to be equipped with a large number of high-performance and high-reliability hydraulic pneumatic and sealing components.

　　 The status quo of the industry is optimistic. The composition of the sealing industry has formed a state-owned enterprise, private enterprise, and three-capital three-legged state, with output value basically accounting for one third each. State-owned enterprises are intensifying their reform efforts; a large number of private enterprises are rising rapidly; foreign capital has entered in large quantities, and the world's leading companies have basically carried out joint ventures, sole proprietorships, and sales in China, showing a trend of manufacturing transfer to China. In terms of technology, the leading products of state-owned enterprises are mainly introduced and independently developed in the 1980s, basically at the international mid-range level; private enterprises mostly focus on medium and low-end products, but they accumulate funds rapidly, use existing domestic technology and gather experienced talents , The technological level has progressed rapidly, and its product quality, variety and service have been continuously improved in competition; foreign-funded enterprises mainly focus on medium and high-end products, and the technical level is equivalent to that of foreign companies, providing supporting facilities for domestic joint ventures and wholly-owned enterprises with high-end mainframes and key projects.

　　 With the rapid development of my country's economy, the use of hydraulic and pneumatic to realize transmission and control of various mechanical equipment is increasing, and the technical requirements for seals are increasing. my country's fluid power product market has developed rapidly, ranking first in developing countries except the United States, Europe, and Japan. my country's imports are also increasing, and the market has great potential for development.

　　 The potential for future development is huge. With the improvement of industrialization and automation, mechanical equipment needs a large number of high-performance and high-reliability hydraulic pneumatics and seals. In addition to the Three Gorges of the Yangtze River, South-to-North Water Diversion, West-East Gas Transmission, West-East Electricity Transmission, Qinghai-Tibet Railway and other century-old projects, there are also a large number of large coal mines, oil fields, open-pit iron mines, power stations, airports, ports, high-speed railways, high-grade highways, etc. Key projects, as well as a large number of urban construction and residential construction. For this reason, the continuous increase in the workload of loading and unloading of earth and stone, coupled with the development of modern logistics and the application of new processes, new technologies and new materials, will keep the domestic demand for construction machinery increasing for a long time. In short, the above products require a large number of high-pressure plunger pumps, high-pressure gear pumps, high-torque motors, wheel motors, multi-way valves, cylinders, pipe fittings, pipeline assemblies and oil filters, etc., for supporting and repairing hydraulic and The seal market will face a new period of great development. Among them, construction machinery is the user of hydraulic products, accounting for 42.3% of the industry's sales. The proportion will expand in the future, so the development trend of construction machinery is very important. It is also reported that the imported hydraulic parts for excavators, road machinery, cement mixers and other accessories produced by domestic enterprises each year amount to more than 150 million US dollars. In short, the market for hydraulic and sealing parts for construction machinery supporting and maintenance will face a new era of great development.
