& gt Dongying Haisen Seal Technology Co., Ltd.

Dongying Haisen Sealing Technology Co., Ltd. is located in China Youshi University Science Park. Is a high-tech enterprise focusing on the research and development of new fluid-lubricated non-contact mechanical seal technology and the production and sales of its products. With the technical support of China Youshi University and the backbone of more than ten professors, doctors and graduate students, the company has formed a patented technology with independent intellectual property rights with the help of years of experience in research and development of fluid seals. The company has strong technical force, the main designers have master's degree or above, can independently develop and apply fluid sealing technology, and can provide users with the most economical and reasonable sealing system solution in the shortest time. In recent years, it has undertaken five major scientific research projects at the provincial and ministerial levels, and reached the international advanced level in mechanism research, structure optimization, software development and new fluid-lubricated non-contact mechanical seal manufacturing. It has won 4 provincial and ministerial awards, 5 bureau-level awards and 4 national patents with independent intellectual property rights. The company has established "experimental device of pump sealing technology", "experimental device of low-speed mixing equipment" and "multifunctional high-speed sealing experimental device", which can realize automatic measurement and control, and is equipped with complete sealing performance and quality monitoring instruments, such as high-precision imported surface profiler, micrometer of end film thickness, sealing quality tester and automatic grinder. It has laid a solid material foundation for the research and development and industrial application of new fluid-lubricated non-contact mechanical sealing technology.
