The 3.3 m diameter rotary shield plug bearing produced by Liaoning General Machinery Group passed the five tests including appearance, size, cleanliness, ultrasonic detection and static detection. It has been shipped recently and will be installed in China. Neutron reactor".
PVC Waterproofing Membrane is an advanced-formula, heat-weldable PVC thermoplastic membrane that is designed for long-term weather-ability and performance. The physical properties of the membrane are enhanced by a tenacious, weft-inserted polyester fabric that is encapsulated by thick PVC- based top and bottom plies.
The smooth surface of the PVC membrane allows for a total-surface fusion and permanent weld, creating a consistent, watertight, monolithic roof assembly. PVC can be used in adhered and mechanically fastened systems.

As the largest energy sector in the National 863 Program, the “Fast Neutron Reactor†will be applied to important projects such as power generation and value-added nuclear fuel. Entrusted by the China Institute of Atomic Energy, China First Heavy Machinery Group Co., Ltd. is responsible for the equipment manufacturing of this project. And whether the rotating shield plug bearing "fast reactor" can work normally will play a vital role. As a long-term supplier of China's No. 1 Heavy Machinery Group, in 2002 Liaoning General Machinery Group, with its high level of research and development capabilities and diversified product structure, beat other well-known domestic enterprises and became a professional manufacturer of this project.
The predecessor of Liaoning General Machinery Group is Anshan Bearing Factory. Because of its strength, it has become the professional manufacturer of bearings designated by the former Ministry of Machinery. After the enterprise was transformed in October 1998, General Machinery Group quickly adjusted its product structure and formed a production pattern of “one factory and three linesâ€, namely the bearing production line represented by super large and the pressure vessel production line represented by oil-free air compressor. A mechanical manufacturing line represented by machining. The group has also acquired 6 companies, and its scale has been continuously expanded, and personnel, technology and capital have been re-integrated.
It is understood that compared with conventional bearings, such rotary shield plug bearings can not be contacted by anyone once they are put into use. Therefore, the materials, processes and other requirements are quite strict, and there must be a strict set of design, processing, installation and operation. The quality assurance system ensures that it is accurate before it can be put into use. In 2002, after the two parties signed the contract and quality assurance agreement, after full technical preparation, the rotating shield plug bearing officially entered the design and production stage. Under the guidance and full monitoring of the experts of China Atomic Energy Research Institute and China No.1 Heavy Machinery Group Co., Ltd., through the unremitting efforts of the employees of Liaoning General Machinery Group Co., the rotating shielded plug bearing was finally developed and produced successfully.
