Large-scale marine crankshaft is a key component of marine diesel engines. It has large weight, high precision, demanding performance and complicated manufacturing process. Its market is basically monopolized by a few countries such as Japan, South Korea, Czech Republic and Spain. In recent years, there has been a global shortage of supply. In the shortage situation, prices continue to rise, and delivery time is getting longer and longer, which has led to the phenomenon of “ships (ship diesel engines), machines and other crankshafts†in shipbuilding in China, which has become a constraint to China’s machine building, shipbuilding capacity and shipbuilding industry. The key issue was thus listed by the state as one of 16 major technical equipment research and development projects.
The first crankshaft of Dalian Huarui Crankshaft Co., Ltd. was officially launched on December 29, 2007. The 6.7-meter-long, 41-tonne crankshaft will be used on the 50,500-ton oil tanker exported by Italy.
Song Jiajing, chairman and general manager of Dalian Heavy Industry·Hangzhou Group, said that the crankshaft is an important symbol of the national shipbuilding industry. The mass production capacity of marine crankshafts with independent intellectual property rights formed by Dalian Heavy Industry and Crane Group will be the world for China. The development of the first shipbuilding power provides strong support.
It mainly consists of hydraulic supports, hydraulic stations, control systems, and sensors.
Hydraulic support is the core component of the hydraulic support system used in mines, which uses hydraulic cylinders as the support force source,
Capable of supporting huge rock weights in underground mines. The hydraulic station provides a hydraulic oil source,
Hydraulic oil is transported to the hydraulic support through pipelines to achieve support function.
The control system is an important component of the hydraulic support system used in mines, which controls and monitors the hydraulic support through sensors and controllers. Sensors can monitor the status of the bracket in real-time, including support force
The controller controls the hydraulic support based on the feedback data from sensors, such as inclination and displacement, to ensure its stability and safety in the mine.
The hydraulic support system used in mines has advantages such as high support force, good stability, and safety and reliability,
Widely used in underground mining industries such as coal mines, metal mines, and non-metallic mines. With the continuous progress of technology and the continuous expansion of applications, hydraulic support systems for mines will continue to play an important role,
Provide strong support for the safe and efficient development of the underground mining industry.
Dalian Heavy Industry·Hangzhong Group's first large-scale marine crankshaft off the assembly line
The first large-scale marine crankshaft manufactured by Dalian Heavy Industry·Holding Group Co., Ltd. was officially launched at the end of 2007 by Dalian Huarui Crankshaft Co., Ltd. through the joint inspection of classification societies and users. This indicates that Dalian Heavy Industry·Zhangzhong Group has already possessed the mass production capacity of large marine diesel engine crankshafts with independent intellectual property rights, which will effectively alleviate and solve the crankshaft bottleneck problem that restricts the development of China's marine diesel engine and shipbuilding industry.
