Longxue Shipbuilding: High Performance Products to Meet the Needs of Large Tonnage Gantry Cranes

Leaving Guangzhou Petrochemical, media reporters went to Siemens' next representative application site - Guangzhou Zhongchuan Longxue Shipbuilding Co., Ltd. (hereinafter referred to as " Longxue Shipbuilding " ). Longxue Shipbuilding is located on Longxue Island in Nansha District of Guangzhou City. The formerly small island of no-manhood has now been built into one of China's modern large-scale shipbuilding backbone enterprises in South China. Longxue Shipbuilding covers an area of 2.53 million square meters, has two large docks, berths, supporting 600 tons gantry crane 4. After its establishment in 2006 , the first-stage production capacity will build 20 vessels and 2.12 million dwt annually. After the completion of the expansion project, the annual shipbuilding capacity has reached 3.5 million dwt.

One Longxue shipbuilding dock configuration of -200 m 2 600-ton gantry cranes and dock II equipped with two 600 tons -176 meters gantry crane is a reporter trip to visit the "hero." Gantry cranes known as "gantry" is an important equipment in the shipbuilding process, the higher the tonnage, the greater the span, it means that the requirements for the motor, inverter and other products higher. The gantry crane span of Longxue Shipbuilding is 200 meters and 176 meters respectively, which is the highest in South China, which determines that the requirements for the electronic control system will be more stringent.

Mr. Liu Longhua, senior engineer and supervisor of Longxue Shipbuilding Production Protection Department, was a very enthusiastic technical expert. At the meeting with reporters, he detailed the happy cooperation process between Longxue Shipbuilding and Siemens. “ The 4 gantry cranes are designed by the CSSC 9th Design and Research Institute, Jiangnan Heavy Industry Co., Ltd. is contracted to manufacture and install, and Siemens is designing, supporting and debugging the electronic control systems. The electronic control systems all use Siemens products and technologies. each AFE rectifier comprising two feedback unit 8 SIMOVERT MASTERDRIVES inverters, a crane management system STEP7-400 PLC station 13 and remote I / O sub-station, an electrical driver's cab and the CMS chamber, a drive motor (including Walking and lifting), high voltage transformers and their power distribution cabinets are also Siemens products. "

Liu Longhua’s supervisor said that the reason why Longxue Shipbuilding chose to cooperate with Siemens was the result of an open tender, which was decided by technical experts from several shipyards in Guangzhou. “ At that time, we mainly considered several points. First, the Siemens gantry crane electronic control system has had many successful cases in the shipbuilding industry. Second, Siemens industrial automation products are widely used in the industrial field. Third, Siemens is an international company with products. Good quality assurance and advanced technology, and fourth, Siemens can provide good technical services. ” And later cooperation did not disappoint Liu Longhua. Siemens’ engineering service capability is strong, product performance is stable and reliable, “ Engineers are also very dedicated. , equivalent to 30 a day to climb the stairs to the top floor of the gantry crane control room to debug, stay for one day. "

Siemens' electronic control system solves several major technical problems for Longxue Shipbuilding: the dual-link crane uses light communication for synchronous control, single-person operation, high safety, and unique cart synchronization The control technology can better solve the problem of vehicle vibration caused by out-of-synchronization; the hooks and upper and lower trolleys have high synchronization accuracy of ±20 mm ; the system has high reliability and low failure rate. And Liu Longhua's supervisor is most recognized as the energy-saving effect of Siemens' electronic control system. "The AFE rectifier feedback unit has an energy feedback function that can convert potential energy into electrical energy, thereby saving a lot of electrical energy. "

In recent years, China's shipbuilding industry has developed rapidly. According to the plan, the Bohai Bay, the Yangtze River estuary, and the Pearl River estuary will all become world-class shipbuilding bases. This also creates a huge market space for industrial automation companies such as Siemens. Currently, 300,000 Siemens shipbuilding dock for Shanghai Hudong 600 tons -170 meters gantry crane, the Dalian shipyard dock 300,000 tons gantry crane of 600 tons -185 meters, Qingdao shipyard dock 300,000 tons gantry crane of 600 tons -219 meters, 600 The tonnage of 182- meter gantry cranes and Jidong Shipbuilding Co., Ltd. provided 200-to- 26- meter, 200- to- 60- meter, and 400- to 3-4.3- meter-long gantry cranes with electronic control systems. The performance is good, and it is believed that it will be more abundant in the shipbuilding industry in the future. The gains.

Guangzhou South Station: High-end applications of low-voltage electrical products

July 14 morning, the car came to a media correspondent on the third leg of the media line activities - Guangzhou South Railway Station. The new railway station, which was just delivered before the Spring Festival this year, is located in Shibian Village, Zhongcun Town, Panyu District, Guangzhou City and is a large modern railway passenger station. This is the end of the Wuhan-Guangzhou high-speed rail. One month ago, the reporter's “ first experience ” of the Wuhan-Guangzhou high-speed rail also vividly remembered . The average speed is 350 km / h, and it takes only 3 hours and 45 minutes. It is more convenient and faster than taking a flight. The clean and orderly management of Guangzhou South Railway Station also left a deep impression on reporters.

Next to the well-ordered exit gates, there is an overwhelming construction site. According to Han Fei, sales manager for building and infrastructure business in Siemens' industrial business field, Guangzhou South Railway Station plans to build 28 high-speed rail lines with the ability to operate at the same time. Only 7 of them are currently in operation. Unopened platforms, parking lots and other facilities are still under construction. In the future, Guangzhou South Railway Station will become the meeting point of the Guangzhou-Shenzhen-Hong Kong Express Rail Link, Wuhan-Guangzhou Passenger Dedicated Line, Guangzhu Intercity Rail Transit, Guizhou-Guangzhou Railway and Nanguang Railway, and will replace the existing Guangzhou Station, with Guangzhou Station and Guangzhou. East Railway Station and Guangzhou North Railway Station together form one of the four major passenger transportation centers of the national railway —the Guangzhou Railway Passenger Terminal planned by the Ministry of Railways of China. At the same time, as the transportation hub of South China, Guangzhou South Railway Station will link Lianyun, Guilin, and Handan in the South, and Hunan, Hubei, Henan, Chongqing, and Beijing in the north. It is the 8- hour economic circle centered on Beijing in the future and Guangzhou as the core. The central axis of the 3- hour economic circle.

Siemens won the main contract of low-voltage power distribution in Guangzhou South Railway Station with its high-tech and high-quality products. It also provided communications and surge arrester additions, as well as distribution boxes and lighting boxes. This is the first high-end application of Siemens low-voltage electrical products in the domestic railway system, and it has withstood many " difficult " tests, and ultimately won the trust of customers. Manager Han Fei recalled to the reporter that in order to ensure the construction period, Siemens worked together with the contractor and user units to work overtime and overcome various difficulties: “The first is the difficulty in transportation. When the distribution cabinet came in, the surrounding roads were not yet available. Completely repaired, bumpy roads, we must pay attention to the protection of distribution cabinets in transit; second is the construction of the harsh environment, because it is a number of projects at the same time, the distribution cabinet is not fully completed when the civil engineering works, so the distribution cabinet must withstand Occupied by dust, etc. Once again, the natural climate is relatively poor, due to the humid and rainy weather in Guangzhou, water droplets often condense in the power distribution room, and power distribution cabinets have a phenomenon of “ sweat. ” However, Siemens power distribution cabinets are highly protective. Grades, these difficulties have withstood and overcome. All of our switches were successful with one-time power operation. "

The successful application of Siemens low-voltage electrical appliances in Guangzhou South Railway Station has knocked the door of the high-end market for the railway industry. As China's high-speed rail construction continues to accelerate, Siemens' high-quality, high-tech products will also have more and more " useful areas. "

China Resources Cement: Saving Energy for One and a Half Years

After the end of the visit in Guangzhou, the media team went to Guangxi to visit the last stop of the trip – China Resources Cement (Pingnan) Co., Ltd. (herein referred to as “ CR Pingan ” ) located in Pingnan County, Guangxi Province. Although he had a hard time, the idea of ​​exploring the practical application effects of Siemens high-voltage inverters has always made reporters full of expectations for this visit. Siemens is committed to assisting industrial enterprises in energy conservation and emission reduction. Prior to this, it has successfully cooperated with Wulan Cement, Qinling Cement, and other methods that use “ contract energy management ” and has achieved energy-saving effects that are satisfactory to users. So, Siemens and this Guangxi's largest cement production base - Cooperation Pingnan China Resources Cement Company and how it?

“ We did not adopt a contract energy management model. The funds for purchasing high-voltage frequency converters were all paid by the company itself. ” Tang Ditian, Assistant General Manager of China Resources Cement Pingnan Co., Ltd., who led the reporter’s visit, said. At present, China Resources Cement Pingnan has equipped seven Siemens Robinson high-voltage frequency inverters with a total installed capacity of 11,400 kilowatts and a power saving rate of 22% . It can save more than 150 million kilowatt-hours of electricity annually, and can save electricity costs annually on average. 76.39 million yuan. Zhao Hui, Deputy Manager of China Resources Cement Pingnan Company stated: “ We can recover all the investment costs in one and a half years. ”

In recent years, the state has increased energy conservation and emission reduction in various fields of industry. The cement industry is one of the key areas. At present, the integrated power consumption of the cement industry in China is less than 110 kWh / ton, while that of advanced cement companies is less than 100 kWh / ton. Internationally, the integrated power consumption of the cement industry is generally 95 to 100 kWh / hour, compared with 85 to 90 kWh / ton for advanced companies. According to reports, the integrated power consumption of Huarun Cement Pingnan in the first half of 2010 was 91.65 kWh / ton, which is close to the international advanced level. This is obviously closely related to the good energy-saving effect of Siemens high-voltage inverters.

In addition to the high-voltage inverters, a number of other Siemens products have also been successfully applied in China Resources Cement Pingnan Company, including high-voltage inverters, DCS , dosing feeders, speed reducers, motors, radar level gauges, flow meters , temperature transmitters, gas analyzers, etc. The waste heat generating unit of China Resources Cement Pingnan Company has applied the Siemens PCS7 system as the main control system. Its stable and reliable performance and the good technical service of the Siemens team have been recognized by users. Siemens has also been recognized as a long-term strategic partner by users.

Cement production is the upstream of the infrastructure construction industry. Under the environment of rapid economic development in China, the cement industry also faces enormous market opportunities. Under the demand of technological upgrading and energy saving and emission reduction in the whole industry, Siemens' cooperation with customers in the cement industry will also be deepened. According to General Manager Tang, China Resources Cement will also purchase 3 Siemens Robinson high-voltage frequency converters for energy-saving transformation in the second half of this year, and plan to increase the integrated power consumption of cement to the international advanced level.
