INVESTIGATING THE EFFECT OF TEMPERATURE ON RING STUFFING BOX PACKINGS OF BELL INDUSTRIES TO ACCOUNT FOR CHANGING WORKING CONDITIONS

贝尔工业公司是一家总部位于埃德蒙顿的公司，自1962年以来一直在能源行业工作。贝尔工业拥有自己的聚合物产品系列。其中一种产品是环填充盒，用于在高温和高压下密封杆和活塞。密封圈是一种纤维增强聚合物复合材料产品，由优质橡胶和芳纶(芳纶®)短纤维增强，芳纶短纤维通常用于井口填充盒和黄铜片，以帮助自洁抛光杆。几家密封杆和活塞的工业终端用户已向贝尔工业公司表示，他们现在需要可承受高达330°C(625°F)温度的环型填料和密封件。目前，关于高温、高压蒸汽对芳纶纤维增强复合材料的影响的数据很少。贝尔工业希望探索温度和压力对聚合物材料的影响，并开发模型来先验预测材料在相同条件下的性能。本提案准备进行基础研究，以便了解新的操作条件对现有产品和数据的影响，以证明如有必要，开发先进材料是合理的。为此：(1)需要对产品进行彻底的热机械分析，以预测并记录其在不同温度下的行为，以及(2)对这些纤维增强橡胶密封件中的温度分布进行表征。Ayranci博士的团队提出了一个项目，对温度和压力对现有产品的影响进行初步分析，并根据初步调查结果建议对材料(纤维和橡胶)和/或组合进行潜在的修改。

Bell Industries is an Edmonton-based company working in the energy industry since 1962. Bell Industries has its own line of polymeric-based products. One of these products is the ring stuffing box packings that is used for sealing rods and pistons at elevated temperatures and pressures. The ring is a fiber-reinforced polymeric composite material product that is composed of high-quality rubber that is reinforced with short Aramid (Kevlar®) fibers that are typically used in wellhead stuffing boxes and brass flakes to help with self-cleaning of the polished rod. Several industrial end-users of sealing rods and pistons have indicated to Bell Industries that they would now like ring-type packings and seals that can withstand temperatures of up to 330°C (625°F). Currently, there is little data on the effects of high-temperature, high-pressure steam on fiber-reinforced composite materials that consists of Aramid fibers. Bell Industries wishes to explore the effects of temperature and pressure on the polymeric material and develop models to predict, a priori, the performance of the material under these same conditions. This proposal is prepared to conduct fundamental research in order to understand the impact of the new operating conditions on the existing product and data to justify the development of advanced materials, if necessary. For this purpose: (1) a thorough thermo-mechanical analysis of the product to predict and document its behavior at different temperatures and (2) characterization of the temperature distribution in these fiber-reinforced rubber seals will be required. Dr. Ayranci's team proposes a project to conduct a preliminary analysis on the effects of temperature and pressure on the existing product and recommend potential modifications to the materials (fibers and rubber) and/or combinations that will be based on the results of the preliminary investigation.
