China's construction machinery industry
China's construction machinery industry by leaps and bounds in recent years, is an indisputable fact. 2011, China's construction machinery industry sales revenue exceeded 500 billion yuan, an increase of 17% or more. Not only the amount of both industry-wide sales ranked first in the world, but also to hydraulic adaptors meet nearly 90 percent of China's domestic market demand. But in engineering machinery manufacturing power known, in the long-term dependence on imports of key components, resulting in 70% of the industry profits over to people. The lack of high-end hydraulic parts, to become the industry's "seal throat pain."
On hydraulic components, it is the crucial parts of construction machinery products, one of which both reflect the whole construction machinery operating efficiency, operational simplicity and comfort, but also the whole work of the main sources of error. For a long time, in the high-pressure high flow hydraulics, domestic parts enterprises enterprise products also difficult to meet the matching requirements of the host, which makes imports become the only option, especially in the excavator product.
At present, China has become the main excavator production and sales metric hydraulic fittings market, in 2011, Sany excavator sales over 20,000 units for the first time surpassed Japan Komatsu sales in China, becoming the excavator and the whole construction machinery industry a bright spot. But worrying is that domestic producers needed excavator hydraulic pumps, hydraulic valves, hydraulic motors and hydraulic cylinders are still several foreign companies controlled excavator hydraulic system is still mainly rely on Japanese and Korean products supporting.
Thankfully, the key components missing issues, has been in the domestic construction machinery industry has attracted wide attention. According to Suzi Meng said that some of the core components by OEMs in Germany, the U.S., South Korea and other countries in the business, now in the engine, multi-way valve, hydraulic pumps, hydraulic power units, motors and other walking on the development of high-end components breakthrough. In addition to Shantui Machinery, Jiangsu Hengli, the radius of the support, Nakagawa as the representatives of a number of hydraulic components and attachments emerging manufacturing enterprises have developed rapidly, especially Shantui Machinery, Jiangsu Hengli, have already reached the world construction machinery parts the advanced level, a huge space for future development.
China Hydraulics Pneumatics & Seals Association Changsha Bossen said that in 2009 to 2011 three years, a sharp increase in investment in fluid sealing industry, plans to invest over 300 billion yuan, of which the NDRC, the Ministry of approval has been issued has invested more than 100 billion, more than the hydraulic pipe fittings previous five-year plan to invest 11 combined. Benefited from the country's attention on the basic parts and support, including engineering machinery hydraulic parts, including key parts of the investment boom seems to have been formed.
the hydraulic valve works
1) Industrial (also known as fixed equipment, which is compared in terms of mobile machinery) valve is usually 4 pass type, that is, four main ports: pressure oil imports is P, load ports A and B, leading to the tank return port T. The rest of the control port, load pressure LS port, drain port and so can not be calculated in a few pass inside.
2) Those who need to control the oil on the main stage pilot control components, such as electro-hydraulic adaptors valve, there is a source of pilot oil return oil how to deal with the problem. This is the performance of metric hydraulic hose fittingstechnology flexibility to the user to stay out of the system according to the actual needs of a choice. Here:
X - outside the system from the main control oil inlet (called external control, if it comes from the P port, said internal)
Y - control of oil taken directly to tank port (known outside the back (leakage), if you return to port T, called back within (internal leakage))
L - valve leaking oil alone lead to tank port
3) incidentally mentioned that the pilot control oil processing, according to the need for rational combination:
External control, external back; external control, internal back; internal and external back; internal control, internal back.
4) incidentally mentioned, for the mouth of the leaked oil L, external pilot oil return must lead directly back to the tank (or through the filter), should never be brought together into the main oil return port T be lead back to the tank. In this case the proportion of the servo system is more sensitive.
