Related Introduction

The technical requirements for mechanical seals are relatively high, and a variety of knowledge theories coexist. Take mechanical seals or floating ring seals as an example. To solve these sealing problems, it is necessary to consider the influence of the deformation of the stator and rotor components due to the force and temperature, as well as the impact of vibration and wear on the hydrodynamic characteristics of the fluid film. That is to say, it is necessary to study and analyze the sealing problem from the aspects of fluid dynamics, elastic theory, heat transfer, tribology and vibration theory. This is the theoretical foundation and basic knowledge that engineers and technicians engaged in sealing technology should possess.

With the mission of being green, intelligent and efficient, and forging quality with innovation, we are dedicated to providing Mechanical Seals Yc. Roa (FLOWSERVE RO) and services to the community. We are currently undertaking a new set of strategic transformations and upgrades to enhance our overall manufacturing capabilities. The five elements of our corporate culture include: safety, responsibility, learning, sunshine, and hard work.
