After realizing the further optimization of the market for large container ship propulsion efficiency, Mann Diesel & Turbo recently announced the launch of two important engines for their engine plans.
Currently, two new large two-stroke engines, the G95ME-C9.2 and S90ME-C10.2 engines, are being developed, and the company has announced details to select these engines for the optimized ship project that is entering the design phase.
According to Mann Diesel and Turbo, the two engines belong to the largest and most powerful engine that the company has never introduced to the marine two-stroke engine market.
The drawing delivery time for the S90ME-C10.2 engine and the G95ME-C9.2 engine is 2-4 months and 9-11 months after the order is confirmed. Depending on the design speed, the two engines can be configured differently. Although the S90ME-C10.2 engine is basically the same as the existing S90ME-C9.2 engine, if the specific project requires, the current L3-L4 speed can be reduced to 76 rpm in 76 rpm. Change the basic design of the S90ME-C9.2 engine.
The S90ME-C10.2 engine with a bore of 900 mm and a stroke of 3260 mm will share all the dimensions of the S90ME-C9.2 engine. This design difference with increased average effective pressure results in modifications to the crankshaft journal bearing design and web thickness, including an adaptive modification of the connecting rod.
The supercharger and hydraulic power supply meet the normal power/speed output. The size and number of hydraulic pumps are slightly different. The G95ME-C9.2 engine has a larger bore and stroke than the S90ME series, with a bore of 950 mm and a stroke of 3640 mm. This means that the average speed of the piston is 9.23 m / s, compared to 9.13 m / s. The average effective pressure is the same as the average fuel consumption. At a pressure of 21 bar, the average fuel consumption is 166 (L1-L3) and 160 (L2-L4) g/kWh, respectively.
The configuration of the G95ME-C9.2 engine helps to further reduce the speed to 80/70 rpm. Mann Diesel & Turbo said it would help a new generation of ultra-large container ships, using large diameter and high efficiency propellers to increase efficiency and avoid unnecessary sacrificing ship speed.
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
