Proportion of application fields of hydraulic station

2022-08-24 17:05:12

Construction machinery is a large user of hydraulic products, accounting for 42.3% of professional sales. This proportion will expand in the future, so the development trend of construction machinery is very important. It is estimated that by 2013, the annual demand for hydraulic excavators will reach 60000 to 80000, bulldozers nearly 10000 (above 120 horsepower), loaders about 100000 to 120000, graders about 2000, road rollers about 15000, engineering cranes about 20000, forklifts about 80000, and cement mixers nearly 10000.

As we all know, the utilization rate of pneumatic technology of hydraulic station in metallurgical equipment reaches 6.1%~8.1%, accounting for about 10% of the total equipment cost. According to occupational statistics and analysis, hydraulic and pneumatic products directly provide supporting equipment for metallurgical occupations, accounting for 14.5% and 9% of sales respectively (excluding retail). It is reported that the metallurgical profession imports tens of millions of dollars of hydraulic, pneumatic and sealing products every year for protection. Therefore, the matching and protection of metallurgical and mining equipment host will significantly increase the demand for hydraulic and pneumatic seals. Metallurgical and mining equipment will require many plunger pumps, cartridge valves, solenoid valves, proportional valves, servo valves, oil cylinders, complete hydraulic systems, pneumatic components and many seals.

By 2011, the annual demand for plastic machinery will reach about 150000, of which injection molding machines account for about 40%. There are about 400000 plastic machines in China now, and it is estimated that they will reach about 800000 by 2013. Although small and medium-sized injection molding machines now have the development trend of adopting electric drive, according to analysis, in the next few years, due to plastic products and costs, electric drive will still be widely used in China in addition to high-precision, high-efficiency and high-quality products. Therefore, the market demand for hydraulic, pneumatic and sealing parts for plastic machinery matching and repair will continue to grow rapidly.

Plastic machinery products demand a lot of medium and high pressure variable plunger pump, vane pump, cartridge valve, solenoid valve, proportional valve and servo.
