Dover Precision Components Expands Its TruTech High Performance Materials Portfolio

TruTech™ Materials Provide Foundation for Next-Generation Reciprocating Compressor Sealing Solutions

Dover Precision Components is proud to announce the expansion of its TruTech™ materials brand, delivering the latest advances in polymer science to enhance the performance and reliability of critical components in rotating and reciprocating machinery.

Dover Precision Components has made significant investments in its Materials Technology initiative to fully integrate materials research with engineering expertise and practical experience in machinery applications. A world-class team of material scientists has been assembled to develop proprietary TruTech polymeric materials, optimize process parameters and ensure product quality. A dedicated materials laboratory featuring state-of-the-art mechanical, chemical, optical and thermal analysis equipment, as well as advanced friction and wear testing, provides the necessary tools to fully evaluate materials and their signature properties. In addition, the recently constructed Dover Precision Components Innovation Lab allows testing in real-world environments to transform material properties into customer benefits.

Early results of this investment have already shown promise. The Dover Precisions Components Materials Technology initiative has introduced new materials for high-pressure, non-lubricated reciprocating compressor applications and developed new manufacturing methods to provide greater freedom to product development engineers.

“Our TruTech materials provide a significant advantage in meeting customer needs for performance in demanding operating conditions and position us to serve the next generation of reciprocating and rotating machinery,” said Jane Kober, Vice President of Marketing and Innovation for Dover Precision Components. “Our expertise enables us to develop, test, and deliver reliable solutions using the most advanced polymer materials.”

TruTech materials are designed for optimum performance characteristics in a variety of operating conditions and have decades of proven success in the field. They are formulated from high performance polymers, such as PTFE, PEEK, UHMWPE, PPS, polyimide and other high-temperature aromatic polymer materials, in combination with state-of-the-art fillers, carefully selected and formulated to satisfy application requirements. All formulation, manufacturing and testing is done in-house to ensure high quality standards and full traceability.

Broad research and development capabilities allow complete control of the material development process, from material composition and processing through manufacturing and product testing. Maintaining these capabilities in-house provides Dover Precision Components the flexibility to customize material solutions for specific applications and operating environments. New materials receive intensive laboratory analysis and undergo comprehensive testing before release to the field.

The Dover Precision Components Materials Technology initiative is currently developing material solutions to extend the useful life of Cook Compression® packing rings, wiper rings, piston rings and rider rings, as well as enhance performance in non-lubricated environments and process gases, such as hydrogen. The expanded TruTech materials portfolio also includes materials formulated to extend the service life of Waukesha Bearings® fluid film bearing products and Inpro/Seal® Bearing Isolators and Air Mizer® shaft seals.

摘要

带有 “PEEK” 聚合物轴衬轴瓦的大型可倾瓦径向 (TPJ) 轴承在一系列工作条件下进行了测试,这些条件代表着石化发电厂中使用的涡轮发电机遇到的那些工作条件。 直径为 500 mm 的测试轴承具有四个偏心支撑轴瓦、滚珠和球窝枢轴、枢轴配置之间的负载、“定向润滑”和流体静力顶升功能。 这些测试对轴表面速度范围在 40 m/s 与 95 m/s 之间、最大特定负载为 4.75 MPa 时轴承的静态和动态行为进行了特征描述。 先前在带白合金轴衬轴瓦的相同轴承上调查了类似的测试条件,从而可实现直接比较。

本论文介绍了带聚合物轴衬轴瓦的可倾瓦径向轴承的热弹塑性流体动力 (TEHD) 模型,并且对照实验测试数据对该模型进行了验证。

实验数据以及数值结果揭示并证实,在高特定负载下使用带聚合物轴衬轴瓦的可倾瓦径向轴承可实现出色的性能。
