Mechanical seals: some developments in face materials
نویسنده
چکیده
Carbon has been used as a face material in mechanical seals for well over fifty years. The first grades of carbon used were developed from carbon electrical brush materials, but the continuous increase in the severity of mechanical seal operating conditions has necessitated ever improving grades of carbon. This paper details some of the means available to the carbon technologist to achieve these improvements and gives examples of some special applications.

Since the introduction of mechanical seals in nuclear boiling water reactor (BWR) feed pumps operating with high drive ratings, keeping mechanical seal reliability high became a challenge. A problem also encountered in fossil feed pump applications using similar electrically low conductive feed water, referred to as Combined Water Treated (CWT) feed water operation. After a short number of oper...

The end face-seals joint simultaneously the function of seal, bearing and heat exchanger. In order to improve the design of end-face seals the analysis of this type of joint by means of finite element method, was developed. The temperature distribution is indispensable to the analysis of displacement and stress in this type of face seal. In this work the values of temperature and stress in end-...

The interaction of work fluid mechanics with that of the rotary system itself, basically composed of axes, bearings and rotors, is performed by inserting equivalent dynamic coefficients in the mathematical model of the rotor, the latter being obtained by the finite element method. In this paper, the dynamic coefficients of inertia, stiffness and damping of the flat seals analyzed here are evalu...
متن کاملApplication of Tribology in Aircraft Engine Sealing Technology
The seals are the important component of the aircraft engine to prevent leakage of gas or oil. Because the contact and friction problems have a great influence on the performance of the seals, the concept and theory of tribology is already widely applied in research and design processes of advanced seals. This report selected three kinds of representative seals which are co...
