"12L high-efficiency, energy-saving and environmental protection natural gas engine development project" has a total investment of 40,409,700 yuan. Through nearly three years of technical research and accumulation, Hualing has completed performance and emission development for four power segments of natural gas 410, 390, 375 and 350 horsepower. Mechanical development, combustion development, development of component options, and road testing and development meet the national five emission standards and have the potential to upgrade Euro VI emissions. B10 has a life expectancy of 1 million kilometers, and has the capacity for mass production. The engine structure adopts in-line 6-cylinder, integral cylinder head, four-valve, overhead camshaft and rear gear train; adopting electronically controlled gas injection system, high-pressure fuel injection pressure is 1800-2000 bar. The products have passed the certification of the National Automobile Quality Supervision and Inspection Center and have formed an industrialization capability. During the implementation period of the project, 12 kinds of patents were applied for, including 2 patents for invention; 10 patents of various types were authorized, including 2 patents for invention. Five related technical standards have been formulated and more than 20 postgraduates and technicians have been trained. The project has formed good economic and social benefits. The products of this project not only can meet the needs of various models of Hualing Heavy Trucks, but also can supply ship machines, passenger cars, generator sets, and construction machinery. In addition, the project can also promote the use of gas vehicles, increase the use of natural gas, help the expansion of natural gas (CNG/LNG) gas filling and transportation industries, and at the same time, it can stimulate the development of related industries in the province and fill the gaps in the province.
RM Series color mixer is mainly used for
mixing plastics as raw materials, masterbatch and recycled materials. The
mixing can be finished quickly and completely. The ideal structure and design
make it easy for operation, and also easy for clean and maintenance. It is
widely used in the industry of powder metallurgy, pharmacy, chemicals,
foodstuff, ceramic ware and so on.
All parts in contact with material are made
of stainless steel to minimize material contamination.
Vertically mounted blending knife ensure
even mixing of materials.
Function of feeding plus mixing
simultaneously can save time significantly.
