With the continuous development of modern industry and the increasingly stringent environmental protection requirements, the scale of installations in various industries such as oil, chemical, papermaking and electric power industries has been further increased. The fluid delivery machinery used has large shaft diameters, high rotating speeds, more complex and harsh application conditions , In order to ensure the long cycle of equipment and devices, safe and reliable operation of the equipment put forward higher requirements for sealing.
Unocal seal has been committed to the research and development of modern high-end fluid mechanical seal, obtained the research results and patented technology with independent intellectual property rights in hydrodynamic lubrication non-contact mechanical seal, and has achieved significant economic and social benefits . Especially in the new seal mechanism research, structural optimization, software development and experimental research reached the international advanced level. The self-developed seal modular design system can improve the design efficiency by theoretically calculating the seal, analyzing the structure, designing the parts, establishing the part database, and automatically drawing the assembly drawing and the part drawing.
The company has built a "high-speed seal test bench", "medium-speed seal test bench" and "low-speed seal test bench", the compressor, pumps, reactors and mixing equipment sealed operating conditions simulation. The test bed adopts PLC centralized automatic control, which can realize the monitoring of temperature, pressure and rotation speed and carry out effective control. The test data can be recorded and saved in real time by computer. Various curves can be generated according to the need and provide the data foundation for the analysis of sealing performance.
