Ai Changqing, an engineer of the Tianjin Internal Combustion Engine Research Institute, which has long been engaged in the diesel engine emission standard certification, said that the EU IIIB emission standards have imposed stricter restrictions on engine particulate emissions, from the original 0.2 g/kWh to 0.025 g/kWh. To meet this limit, diesel engines must be equipped with particulate filters to solve this problem.
"For a 5-ton loader, domestic engine prices are about 40,000 to 50,000 yuan, while foreign brands need about 70,000 to 80,000 yuan. Enterprises as purchasers can only make less." China Construction Machinery Industry Wang Jinxing, Director of the Association’s Comprehensive Office, frankly stated.
In recent years, the domestic infrastructure construction has been booming. XCMG, Zoomlion, Sany Heavy Industry and other Chinese construction machinery companies have made leaps and bounds in development, and both have proposed a “one hundred billion level†development plan. According to the plan, overseas markets account for a large proportion of them. The implementation of new emission standards will create challenges for the large number of Chinese construction machinery products entering the international market.
At the same time, the built-in duckbill valve industry should take effective measures for the selection of raw materials for castings and forgings, casting processes, forging processes, and heat treatment, so that the castings and forgings can reach the international level in terms of internal quality and appearance quality. On the other hand, it should continue to carry out internal and external leakage research, strict mechanical processing technology, and vigorously promote new types of sealing materials, improve the accuracy of key parts of the product processing, extend product life, so that a two-flange disc valve a short and two leakage phenomenon is fundamental Sexuality improves. Looking at the domestic market, the valve industry has a wide range of development space. According to the forecast of relevant experts, the future market for valves is mainly in the power industry, petrochemical, fertilizer, environmental protection and urban construction industries. They asserted that whoever has good technology, who has excellent quality, and who can continuously develop new products, will be able to take the initiative and stand out in the fierce market competition.
