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. my country's agriculture, water conservancy, energy, transportation and other industries are developing rapidly, and a large amount of machinery and equipment is needed to meet the needs of their development. With the improvement of industrialization and automation level, these equipments need to be equipped with a large number of high-performance and high-reliability hydropneumatic and sealing components.

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

The current situation of the industry is worthy of optimism. Generally speaking, the composition of the sealing industry has formed a three-legged situation of state-owned enterprises, private enterprises, and three capitals, and the output value basically accounts for one third of each. State-owned enterprises are stepping up their reform efforts; a large number of private enterprises are rising rapidly; a large number of foreign capitals have entered, and the world's major companies are basically conducting joint ventures, sole proprietorships, sales and other businesses in China, showing a trend of shifting manufacturing to China. In terms of technology, the leading products of state-owned enterprises are mainly imported and independently developed in the 1980s, and they are basically at the international mid-range level; most of the private enterprises mainly focus on low-end and medium-end products, but they accumulate funds rapidly, make use of existing domestic technologies, and gather experienced talents. , the technical level has progressed rapidly, and its product quality, variety and service have been continuously improved in the competition; foreign-funded enterprises mainly focus on medium and high-end products.

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

Huge development potential in the market outlook With the improvement of industrialization and automation level, mechanical equipment needs to be equipped with a large number of high-performance and high-reliability hydraulic, pneumatic and seals. In addition to the construction of century-old projects such as the Three Gorges of the Yangtze River, the South-to-North Water Diversion, the West-East Gas Transmission, the West-East Electricity Transmission, and the Qinghai-Tibet Railway, there are also a large number of large coal mines, oil fields, opencast 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. To this end, the increasing workload of earthwork loading and unloading, coupled with the development of modernized logistics and the application of new technologies, new technologies and new materials, will keep the domestic demand for construction machinery growing 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, oil cylinders, pipe fittings, pipeline assemblies and oil filters, etc. The market of seals 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, and the proportion will expand in the future, so the development trend of construction machinery is very important. It is also reported that the hydraulic parts imported for the excavators, road machinery, cement mixers and other supporting facilities produced by domestic enterprises each year amount to more than 150 million US dollars. In a word, the market of hydraulic and seal parts for construction machinery supporting and maintenance will face a new period of great development.
