Nanjing Gaojing successfully tested the main propulsion system for the world's largest independent cargo tank asphalt ship

Recently, Nanjing Gaojing Marine Equipment Co., Ltd. successfully piloted the fixed-pitch main propulsion system for the 37000 DWT asphalt ship of AVIC Dingheng Shipbuilding Co., Ltd., and Nanjing Gaojing provided stable operation for the shafting and propeller equipment. Winning the high recognition of the shipowners and shipyards, and obtaining follow-up orders for the project, further consolidating the long-term cooperative relationship with the shipyard.
It is reported that the 37,000 DWT asphalt ship, with a length of 180 m and a ship width of 30.6 m, has a design speed of 14 kn. The ship is the world's largest independent cargo tanker designed for the world's largest asphalt supplier, Koch Industries Sargeant Marine. The shipowner has higher requirements on the fuel economy, speed and vibration of the ship. Through cooperation with domestic research institutes, Nanjing Gaojing has optimized the propulsion system and integrated ship type in many aspects, and equipped the propeller with a vortex fin energy-saving device. Nanjing High-precision design paddles have passed a series of model tests such as open water test, self-propulsion test and air bubble test. The test results meet the design requirements. During the actual trial flight, the speed exceeds the shipowner's requirements, ensuring the fuel economy and energy conservation and emission reduction requirements. The vibration of the ship's propulsion system also fully meets the ship's navigation requirements, and the whole ship runs smoothly.
The successful trial flight of the ship fully reflects the outstanding hydrodynamic design level and the packing capacity of the fixed pitch propeller propulsion system of Nanjing Gaojing Marine Equipment Co., Ltd.

Lighting Aluminium Profile Extrusion Dies


Aluminum alloy lighting material is a material for lighting equipment made of aluminum alloy. Aluminum alloy is lightweight, corrosion-resistant, and has good thermal conductivity. It is suitable for manufacturing various lamps, such as table lamps, floor lamps, wall lamps, etc. Aluminum alloy lighting materials usually have excellent heat dissipation properties, which can effectively dissipate the heat generated by lamps and extend the service life of lamps. In addition, aluminum alloy lighting materials can also be surface treated, such as anodizing, spraying, etc., to increase their wear resistance and corrosion resistance and improve their appearance and texture. Aluminum alloy lighting materials are widely used in lamp manufacturing and have become one of the important materials in the modern lighting industry.

Aluminum alloys are widely used in lighting, mainly in the following aspects:

1. Lamp body material: Aluminum alloy has good thermal conductivity and corrosion resistance, so it is often used as the main body material of lamps, which can effectively dissipate heat and extend the service life of lamps.


2. Reflector: Aluminum alloy has excellent reflective properties and is often used as a reflector for lamps, which can improve the efficiency of light and reduce energy consumption.


3. Radiator: Some high-power lamps, such as LED lamps, will generate a lot of heat. Aluminum alloy has good heat dissipation performance and can be used as a radiator for lamps to prevent the lamps from overheating and ensure their stable operation.


4. Lamp stand: Aluminum alloy has high strength and light weight. It can be used as a light stand for lamps to support the weight of the lamp. It can also reduce the weight of the lamp and facilitate installation and movement.


5. Decoration: The surface of aluminum alloy can be processed in a variety of ways, such as anodizing, electrophoretic coating, spraying, etc., which can change its color and gloss and improve the decorativeness of the lamp.


Therefore, aluminum alloys are widely used in lighting, which can not only improve the performance of lamps, but also improve their aesthetics.
