Piston Rod Coating Material Study of Reciprocating Sealing Experiment Based on Sterling Seal

Reciprocating Equipment Piston Rod Dynamic Elastic-Plastic Deformation Analysis

Analysis of reciprocating equipment piston rod leads to nonlinear elastic-plastic deformation analysis of rod with initial imperfection under axial dynamic load. In this paper a new and effective model and analytical formulations are presented to evaluate dynamic deformation and elastic-plastic stresses of reciprocating machine piston rod. This new method has capability to account for geometric...

study of hash functions based on chaotic maps

توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...

Developments in Dry Running Seals for Reciprocating Compressors

Reciprocating compressors of the crosshead design have sealing elements around the piston and piston rod. These seals can be of lubricated or nonlubricated design. This paper will give details about our R&D-work for dry running piston rod sealings or packings for high pressure applications. Starting with an overview of packing design some details are given about tribological tests. Measurements...
