The expert group believes that the "Full Synchronous Automatic Measurement Bolt Tensile Machine for Manhole Doors of the Hualong One Steam Generator" developed by Raymon Cyber Company has significant advantages over existing products in the market:

1. The wireless bolt elongation data acquisition/hydraulic pump pressure digital control system, which is designed based on the bolt tensile operation process and is fully self-owned intellectual property, has functions such as elongation data comparison and adjustment of nut rotation angle. Data acquisition and oil pump control are convenient and reliable;

2. All bolt residual elongation can be adjusted to meet requirements with one adjustment, which is convenient, fast, and efficient;

3. The fully digital hydraulic pump control system has pressure protection and dual protection functions for elongation and protection, avoiding bolt overloading tensile and ensuring safety and reliability;

4. The tensile system has a large tensile load reserve and strong adaptability to working conditions;

5. The innovative dedicated tools are complete and convenient, and the installation and operation efficiency of the tensile machine is increased by 50%;

6. It realizes single-person operation of manhole door bolt tensile work;

7. The fully synchronous tensile machine, digital control hydraulic pump station, and all individual components have a maximum weight of less than 20kg, reducing the labor intensity of the operators. 

Raymon Cyber Company, as the enterprise responsible for developing the full-synchronous tensile machine for reactor pressure vessels, this time the successful development of the full-synchronous automatic measurement tensile machine for the manhole door of the Hualong One steam generator marks that Raymon Cyber Company has completed the industrial closure for the full-system bolt tensioning operations of the Hualong One system. It has fully realized the technological domestication through independent innovation.
