China General Nuclear Power Research Institute successfully delivered the purchase of PT800 vibration demonstration equipment

The simulation laboratory built by China General Nuclear Power Corporation (CGN) at Beijing Research Institute mainly purchased Valentian's PT800 vibration demonstration equipment. On May 8th, the PT800 vibration demonstration equipment was delivered and the project acceptance was processed. This experimental platform can conduct up to 11 common mechanical fault simulation experiments. We can carry out experimental and scientific research projects such as gearboxes, bearings, motors, couplings, pumps, belts, crank sliders, fans, flexible rotors, shaft crack detection, dynamic balancing, sliding bearings, mechanical friction, and more.

The role of mechanical fault simulator technology

Mechanical diagnosis is becoming increasingly important. Its purpose is to allow maintenance and repair based on early detection requirements for damage, thereby reducing downtime. The vibration generated by the machine is used for analyzing the operating conditions of the machine. These changes in vibration may indicate a deterioration in the condition of the machine. It is important to know what the impact is, as different types of damage are related to the vibration spectrum. Mechanical diagnostic systems can be used to simulate specific types of damage

Study their impact on vibration spectra. And pure measurement practice of vibration (measuring vibration displacement, primary vibration velocity and acceleration, and lead range), the basic unit can be used to study the on-site balancing problem of rigid rotors. The modular structure allows it to adapt to specific requirements. Comprehensive accessories enable various types of destructive faults to be repeatedly simulated, and computer vibration analyzers are used to measure and evaluate mechanical test benches.

China General Nuclear Power Group (CGN), formerly known as Guangdong Nuclear Power Group, is headquartered in Shenzhen, Guangdong Province. It is a central enterprise controlled by the State owned Assets Supervision and Administration Commission of the State Council. CGN is a central enterprise that has gradually grown and developed with China's reform and opening up and the development of nuclear power industry.

China General Nuclear Power Corporation (CGN) takes "developing clean energy and benefiting human society" as its mission. After more than 40 years of development, it has built a 6+1 industrial system, covering nuclear energy, nuclear materials, new energy, non power nuclear technology, digitization, technology-based environmental protection, and other industries

In the financial and other fields, we have 2 mainland listed platforms and 3 Hong Kong listed platforms. As of May 2023, China General Nuclear Power Corporation (CGN) has an installed capacity of over 77 million kilowatts of clean power in operation, including over 30.56 million kilowatts of nuclear power in operation, over 35.15 million kilowatts of domestic new energy holdings in operation, and nearly 12 million kilowatts of overseas new energy holdings in operation. The clean energy project covers 30 provinces and regions across the country, providing clean electricity to 15 countries and regions overseas.

In September 1994, China Guangdong Nuclear Power Group Co., Ltd. was officially registered and established. In April 2013, China Guangdong Nuclear Power Group was renamed as China General Nuclear Power Group, and China Guangdong School Power Group Co., Ltd. was simultaneously renamed as China General Nuclear Power Group Co., Ltd. CGN has been awarded the A-level performance evaluation by the State owned Assets Supervision and Administration Commission of the State Council for nine consecutive years from 2013 to 2021, and has received a "double A" evaluation for three consecutive terms of annual and term evaluations.
