Guodian Longyuan Group's new generation of high-performance tidal generator set was successfully developed

Under the macroeconomic backdrop of national policy support for renewable and clean energy, Longyuan Power Group Corporation seized the opportunity to expand its Jiangxia Chaoshan Power Station. This project involved utilizing the existing No. 6 turbine unit at the station. To preserve the existing pits and runners, a new type of bulb-type horizontal-flow turbine generator was installed. The goal was to incorporate the latest technology along with the power station's extensive operational experience to enhance the efficiency, output, and overall performance of the unit, drawing on lessons learned from medium-sized tidal power stations. Since the project began in April 2005, it has attracted significant attention and strong support from higher authorities, including the Ministry of Science and Technology and the company’s parent group. It was also included in the national "863" high-tech research and development plan. A dedicated engineering team was formed, consisting of Longyuan Power Group Co., Ltd., Tsinghua University, East China Electric Power Survey and Design Institute, and Hangzhou Jianghe Electromechanical Company, among other research institutions. Together, they focused on the design and development of the new unit. On September 8, 2007, the 700MW new unit was completed. After a period of idle commissioning, the unit was successfully connected to the grid at 16:40 on September 11. From the perspective of stand-alone stability and power output, the sixth unit outperformed the others, marking a significant milestone in the modernization of the Jiangxia Chaoshan Power Station and demonstrating the effectiveness of integrating advanced technology with long-term operational expertise.

Auxiliary Equipment

Injection molding is a highly precise and efficient manufacturing process used to produce plastic parts and components. The injection molding machine is the core of this process, but its performance and capabilities are greatly enhanced by a range of auxiliary equipment. These auxiliary machines play crucial roles in ensuring the smooth and accurate operation of the injection molding process.

One of the essential auxiliary equipment for injection molding machines is the hopper loader. This device automatically feeds plastic pellets into the injection molding machine's hopper, ensuring a continuous supply of material. It eliminates the need for manual loading, reducing labor costs and enhancing productivity. The hopper loader can be equipped with sensors and controls to monitor material levels, ensuring that the machine never runs out of plastic.

Another crucial auxiliary machine is the mold temperature controller. Injection molding requires precise control of the mold temperature to achieve optimal part quality. The mold temperature controller regulates the heating and cooling systems of the mold, ensuring consistent and uniform temperatures. This improves the mechanical properties and surface finish of the molded parts, reducing defects and enhancing overall quality.

The cooling system is another vital auxiliary equipment in injection molding. The molded parts need to be cooled quickly and evenly to prevent warping and distortion. The cooling system typically consists of water lines embedded in the mold, which circulate chilled water to rapidly reduce the temperature of the plastic. This not only improves the dimensional stability of the parts but also increases production speed by enabling faster cycle times.

In addition, robotic automation is an increasingly common auxiliary equipment in injection molding. Robots can perform tasks such as part ejection, inspection, and packaging, reducing the need for manual labor and enhancing productivity. They can also operate in hazardous or difficult-to-reach areas, improving worker safety. Robotic automation also provides consistent and repeatable results, enhancing part quality and reducing the potential for human error.

Moreover, material handling equipment such as conveyors and elevators are often used to transport plastic pellets, molded parts, and scrap material throughout the injection molding process. These machines automate the material flow, reducing handling time and minimizing the risk of material contamination or damage.

Finally, quality control and inspection equipment are essential auxiliary tools in injection molding. These may include vision systems, micrometers, and other precision measurement devices. They allow for accurate and consistent inspection of molded parts, ensuring that they meet quality standards and specifications. This not only ensures customer satisfaction but also helps to identify and correct any issues with the injection molding process itself.

In summary, auxiliary equipment plays a crucial role in enhancing the efficiency, precision, and quality of injection molding operations. From hopper loaders and mold temperature controllers to cooling systems, robotic automation, and quality control equipment, these machines and devices work together to optimize the injection molding process and ensure the production of high-quality plastic parts. By investing in the right auxiliary equipment, manufacturers can improve their competitiveness, reduce costs, and enhance overall productivity.
