The review of the power plant new shipbuilding adopts the main shaft shaft generator system and the view of the shipbuilding center of the COSCO Container Lines Co., Ltd. Ma Zhijun Xin Yanlin survey, and also the view of the new shipbuilding using the shaft generator, and the foreword is well known, the 5-transport cost of the ocean-going ship In an upward trend year by year, the world's major shipping companies are trying to reduce the cost of transportation by 5 in order to obtain higher economic benefits, and strive to make the selection of equipments more economical. The economics of ship power stations is a concern. Hotspots, especially for large and medium-sized container ships, are the most prominent. The total capacity of the entire power station has reached 8,01; therefore, the transmission and consumption of the ship's electric energy and its cost must be fully estimated. The main shaft with generator is an important part of the ship power station, it is necessary to re-recognize.
100500 new shipbuilding adopts the main shaft with generator system. The ship's shaft generator with electric generator can be divided into two categories: no frequency compensation type and frequency compensation type. In 980, the ship was built in the Japanese 541 shipyard. The main shaft of the ship series with generator belongs to the shaftless generator with no frequency 该. The main engine of the ship is medium speed diesel boring machine, the running speed is 434. The propeller is variable pitch, and the shaft generator is increased. The speed of the speed gear is increased by 1801. The ship 1 is usually hoisted by the shaft generator separately. However, this type of shaft generator is subject to sea conditions, and when the wind and waves are encountered, the change of the main engine speed will cause the frequency fluctuation of the electric 1 bucket. Have to use the marine diesel generator to supply power again, can not run in parallel with other diesel generators for a long time, can only change the machine for a short time to make the frequency compensation type shaft generator, 0300 is used in 13 ships, is Germany 3 Just touch the company and 4 catch the company's production; for example, the Qinghai Xihe round. It is like a seven-axis shaft generator driven by the main engine, and its rotation speed is changed. Therefore, the phase-to-phase generator of the AC-powered ship grid provides constant-frequency constant-voltage phase AC, rectified active inverter and synchronous adjustment. The reactive power compensation of the phaser, the frequency and voltage automatic adjustment technology, and finally the constant frequency and constant voltage power supply to the ship grid can be used in parallel with the diesel generator set for long-term stability.
The current situation of 2-axis generators For the medium-sized plastic container ships, most of the main engines are claw-low-speed high-power diesel-fired machines. The shaft generators used are all bent on the first batch of containers with frequency compensation type shaft generators. The SIEMENS shaft generator was installed on the ship's Qingtang Tanghe wheel. The power was outside. At the 3 shipyards in Germany, the 13017001 container ship was built. The shaft generator was installed in the same section. Three of the ships were installed, 0 product. The rest are 313 products, and the power is a frequency-compensated shaft generator that was shipped in the early 70s. It is 513 products. Also the first generation shaft generator. The bought hand boat, the Longhai River Xinghai River, installed this kind of shaft generator, the power is 65 003. The shaft generator used in the new shipbuilding in Germany belongs to the first generation in the early 90s, Germany 55 and Germany. The University of Hamburg, 1 ship inspection bureau jointly developed the first generation of shaft generators. The characteristics of the generators are asynchronous shaft generators, eliminating the need for synchronous phase modulators, resulting in a significant cost reduction, the main thyristor and the trigger circuit. It has been combined and the control system uses a programmable controller to improve the reliability of the product. The output power is 970, which can meet the normal navigation of the ship.
More than OOOkW, the above-mentioned manufacturers of the shaft generators in Japan are similar to the German first-generation shaft generators. The control system is relatively simple and clear, and the reliability of the products is high. 3 How far can the auxiliary oils burn? How far can the heavy oils go into the 1990s? All of them have developed 418, 4 and 1 products from Europe. 050 is also almost all diesel engines with flammable heavy oil on the new shipbuilding. There is no doubt that the auxiliary machine and the main engine will produce good energy-saving effect and economic efficiency. However, there are many questions in actual use. And the difficulty, so that some of the heavy-duty oil auxiliary engines have to switch to marine diesel, and the ships that are still burning heavy oil have also encountered a lot of numbness, burning heavy oil, so that the temperature of the entire cabin is raised. The problem has increased. With the reduction of the volume management staff, the situation of the auxiliary engine burning is severe, and in this case. How far the auxiliary engine can be used will be more and more concerned, but the conclusion may not be satisfactory. 4 The view of the ship adopting the shaft generator is 80. From the 1985, the net is 1300, 17, 11 The container ship will not be used after the shaft rolling machine. We have repeatedly thought about why the first batch of container ships built in Germany in 1981, why did the shaft-crowding machine be used on the Qinghai-Tanghe wheel, and 2 was the servant? In 1984, the first batch of ships on the ship, such as the autumn river, was built. After using the shaft generator, 3 after the investigation and economic arguments decided to build the ship after re-use, 4 ship auxiliary machine burning heavy oil prospects, how to buy five 14001's hand ship after the name changed to Taohe wheel, etc. Maersk then built a 3,500 container ship. A shaft generator and a turbine generator were installed on the ship; in 1993, our company installed a 3,0001 container ship on the FIHKEMARVLrLKiv 3800TEUH container ship, and the Jiade network owner built a 3,0001 container generator. The power is 970 to let Jia; in 1996, 03, when you entered 51 to build a 5250 ding container ship, the company was built at the Japan Nagasaki Shipyard to develop a flammable, smashing machine. The most typical is the 6-axis shaft generator. The power is 2 496, 1 ​​container ships. With a power of 2100, your shaft generators have seen a few examples to show the attitude of foreign ship owners to the use of shaft generators for newbuildings. When their new shipbuilding adopts shaft generators, they will be weighed by various arguments and trade-offs. The shaft generators have been loaded since the early 1970s. It has been 30 years old. This has already indicated that the conclusion is 1 pair, new. The shipbuilding used the shaft belt hairpin machine to make a review. At the same time, it also put forward our view. The shaft generator is in the 03. After passing the road, the boat of the Anzhen shaft generator has more than 5 ships. Except for the Tangling River, the shaft generator is still in normal operation. Even if a fault occurs, it can be repaired in time. Especially on some ships, the shaft generator has already relied on the thoughts. The use of shaft generators should be considered comprehensively. For example, the ship speed requires the power matching of the main engine's Majiu shaft generator. Do not take off the shaft generator when the ship is in the boat. In another sense, the shaft generator is used. It can diversify the ship power station and reflect the technical level and management level of a company.
The shaft generator has a good prospect in the medium-sized container ship. We believe that the 030 will also evaluate the ship shaft generator device with reference to the generator shaft reference generator.
