Hudong Heavy Machinery Co., Ltd. held its 12MV 390 high-speed medium-speed diesel engine promotion conference in Shanghai Lingang, marking an important step in the industrialization process. Hundreds of representatives from sea-packing agencies, shipyards, classification societies, design institutes, nuclear power projects and other units attended the meeting.
The 12MV390 machine fills the blank of the domestic independent brand on the 10,000-kilowatt medium-speed diesel engine. The machine has 12 cylinders with a cylinder diameter of 390 mm, a stroke of 550 mm, a single-cylinder power of 850 kW, a rated speed of 600 rpm, a fuel consumption rate of 175 g/kWh, and a lubricating oil consumption rate of 0.8 g. / kWh, the maximum burst pressure is 250 bar, the average effective pressure is 25.9 bar, the fuel injection pressure of the fuel common rail system is 2000 bar, and the emission meets the requirements of the International Maritime Organization (IMO) Tier II limit, if equipped with selective catalytic reduction ( The SCR) aftertreatment device meets the Tier III limit requirements and features low fuel consumption, environmental friendliness, safety and reliability, and easy maintenance.
At the end of 2015, the 12MV390 machine was officially unveiled at the China International Maritime Exhibition and was approved by the China Classification Society (CCS) in May this year. At present, the accumulated operation time of the 12MV390 prototype has exceeded 200 hours. The test results show that it has reached the design goal in terms of fuel consumption and emission performance indicators, and can be put on the market after completing the reliability test of parts and components.
The MV390 series medium speed machine target market is mainly in two areas: marine power, which can be applied to 3,000-10,000 tons of offshore and inland vessels, large engineering vessels, official vessels, luxury cruise ships, large liquefied natural gas (LNG) vessels, etc.; In terms, it can be applied to large-scale land power stations, nuclear power emergency units, and offshore platforms.
The person in charge of the 12MV390 machine project introduced that the localization rate of this type of machine reached 72%, and there is a lot of room for improvement in the future. Hudong Heavy Machinery is actively strengthening cooperation with domestic suppliers in key components such as superchargers, fuel injectors and bearing bushes. Hudong Heavy Machinery plans to complete the manufacture and testing of the V-type diesel engine prototype of the mechanical fuel injection system in September 2017, and complete the design of the mechanical injection system in-line and dual-fuel system engines. The production of dual-fuel engines will be completed in 2018. test.
Aluminum Core Panel is a kind of Aluminum Composite Panel.As a new decorative material, aluminum plastic composite board (also known as aluminum plastic plate) was introduced from Germany to China in the late 1980s and early 1990s. With its economy, diversity of optional colors, convenient construction method, excellent processing performance, excellent fire resistance and noble quality, it is rapidly favored by people.
The unique performance of aluminum-plastic composite board determines its wide application: it can be used in building exterior wall, curtain wall panel, old building renovation, interior wall and ceiling decoration, advertising signboard, display platform, purification and dust prevention engineering. It belongs to a new building decoration material.
