Shanghai Electric's nuclear power department staff last week said that this year will complete the production and manufacture of the prototype of the wet stator stator pump of the nuclear power station Shidao Bay CAP1400 demonstration nuclear power plant.
Tiltrotator testing is the process of evaluating the performance, functionality, and safety of a tiltrotator attachment used in construction equipment, such as excavators. A tiltrotator is a hydraulic attachment that allows the operator to rotate and tilt the bucket or other attachments, providing increased flexibility and efficiency in various construction tasks.
An excavator attachment is a tool or accessory that can be attached to an excavator to enhance its functionality and performance. These attachments are designed to perform specific tasks and can be easily attached and detached from the excavator, depending on the job requirements. Some common excavator attachments include:

Shanghai Electric said that the completion of the CAP1400 wet stator main pump prototype manufacturing is the key task for this year. At present, Shanghai Electric is the only domestic manufacturer of this equipment. The equipment is mainly used in the manufacture of third-generation nuclear power projects and can be applied to nuclear power projects such as Lufeng, which are carrying out preliminary work.
According to the introduction of National Nuclear Power Technology Company, the demonstration power station is located at the Shidao Bay site of Rongcheng, Weihai City, Shandong Province. It is planned to build a third-generation passive nuclear power demonstration unit CAP1400 PWR nuclear power unit with independent intellectual property rights in China, with a design life of 60 years and a stand-alone capacity. 1.4 million kilowatts. The project is one of the 16 major science and technology projects identified by the National "Summary of the Medium and Long-Term Development Plan for Science and Technology (2006-2020)."
At present, the preliminary feasibility study documents for demonstration power plants have passed the review and the feasibility study report has been completed. According to the work plan, a work order was issued in January 2013 and the first tank concrete (FCD) was poured on April 30, 2013 and put into operation in 2017.
During tiltrotator testing, various aspects are assessed, including:
1. Rotation and tilt capabilities: The attachment's ability to rotate and tilt smoothly and accurately is evaluated. This involves testing the range of motion, speed, and precision of the tiltrotator.
2. Load capacity: The attachment's load-bearing capacity is tested to ensure it can handle the specified weight limits. This involves subjecting the tiltrotator to various loads and evaluating its performance under different conditions.
3. Hydraulic system performance: The hydraulic system responsible for controlling the tiltrotator's movements is tested for efficiency and reliability. This includes assessing the responsiveness of the hydraulic controls and evaluating any potential leaks or malfunctions.
4. Safety features: The tiltrotator's safety features, such as overload protection, emergency stop mechanisms, and locking mechanisms, are tested to ensure they function properly and provide adequate protection for the operator and surrounding personnel.
5. Durability and endurance: The attachment is subjected to rigorous testing to evaluate its durability and endurance under real-world construction conditions. This involves simulating various work scenarios and assessing the tiltrotator's ability to withstand wear, tear, and potential damage.
6. Compatibility and integration: Tiltrotators are designed to be compatible with specific excavators or other construction equipment. Testing involves verifying the attachment's compatibility with the designated machinery and assessing its integration and ease of installation.
Tiltrotator testing is crucial to ensure the attachment meets performance standards, adheres to safety regulations, and functions reliably in construction applications. It helps identify any design flaws, manufacturing defects, or operational issues that need to be addressed before the tiltrotator is used in the field.
