Determining the proper solution for a sealing and bearing application requires expertise in many areas, such as sealing technology, fluid dynamics and material science.
空气控制联接 - 热塑性轴承Air Control Linkage - Thermoplastic Bearings客户希望用使用寿命更长，免维护的产品替换现有的铜轴套。 The customer wanted to replace an existing bronze bushing with a longer-life, maintenance-free product.解决方案 HiMod轴承延长了设备的使用寿命和可靠性，并延长了预防性维护程序之间的时间间歇。 The HiMod bearing extended the life and reliability of the equipment and increased the length of time between preventive maintenance procedures. 结果 HiMod轴承表现非常出色，设备的使用寿命也得到了显着改善。 The HiMod bearing performed exceptionally well and the life cycle of the equipment was substantially improved. 维护成本大幅降低，产品安全性和可靠性也有所提高。Maintenance costs have been substantially reduced and there has been an increase in product safety and reliability. 工况 +177°C / +350°F 摆动 Oscillating movements 内部密封 Internally sealed 高振动 High vibration 产品 HiMod - 高性能热塑性轴承 HiMod - High Performance Thermoplastic Bearings 弹性引气管高温密封High Temperature Seal For Flexible Bleed Air DuctAIR DUST客户想更换在高温压缩下失效的硅胶O形圈，新设计必须保持当前的杆和孔直径以及沟槽宽度。 The customer wanted to replace the existing silicone O-Ring, which failed under compression set at high temperature. The new design had to maintain current rod and bore diameters and groove width. 此外，新设计必须通过300,000次循环的压力脉冲测试，具有严格的泄漏要求。 In addition, the new design had to pass a pressure pulse test of 300,000 cycles, with stringent leakage requirements. 解决方案 标准TurconVarisealM2，带有TurconT11护套和重载V形弹簧 Standard Turcon Variseal M2 with a Turcon T11 jacket and heavy load V-spring 结果 指定的密封件通过了压力循环试验，满足了所有性能要求，延长整个热引气系统的使用寿命，并减少所需维护。 The specified seal passed the pressure cycle test, met all of the performance requirements, extended the operational life of the entire hot bleed air system, and reduced the required maintenance. 工况 0.4 to 1.2 MPa / 60 to 170 psi -54°C to +260°C / -65°F to +500°F 慢速往复运动 /静态 Slow reciprocating / Static 热发动机引气 Hot Engine Bleed Air 产品 Turcon Variseal M2 (V型弹簧施力杆密封) Turcon Variseal M2 (V-spring-energized rod seal) 适用于超低温喷枪的聚氯三氟乙烯（PCTFE）夹套 PCTFE Face Seal For Cryogenic Paint Blaster装有O形圈的装置在温度低于-90°C / -130°F时会发生过多泄漏。 当工况所需的工作温度低至-253°C / -423°F时，需要新的密封设计。 Units fitted with O-Rings experienced excessive leakage at temperatures below -90°C / -130°F. With desired operating temperatures as low as -253°C / -423°F, a new seal design was needed. 解决方案 TurconVarisealWF，带有聚氯三氟乙烯（PCTFE）夹套和重载Slantcoil弹簧 Custom Turcon Variseal WF with a Polymonochlorotrifluoroethylene (PCTFE) jacket and a heavy-load Slantcoil spring 结果 工况 20 ～ 400 psi 高压燃油泵的聚四氟乙烯（PTFE）端面密封PTFE Face Seal For High-Pressure Fuel Pump因为使用的O形圈压缩变形和硬度退化，客户寻找其它可替代的密封设计。 Compression setting and degradation of the previous 80 durometer O-Rings caused the customer to search for a replacement seal design. 新密封件必须适合现有沟槽，提供更长的使用寿命和更佳的可靠性。 The new seal had to fit into the existing gland, provide longer life and better reliability. 解决方案 角部加强挡圈的TurconVarisealHF，配有TurconT01夹套和重载螺旋弹簧
Custom-extended heel Turcon Variseal HF with a Turcon T01 jacket and heavy-load helical spring 新密封件安装在原有沟槽上，其防泄露性能超出客户预期 The specified seal fitted the existing gland and provided leak-tight performance that exceeded the customer's specifications. 避免密封件过早失效，维护成本显著降低 Premature failure was eliminated and maintenance costs were significantly reduced. 工况： 产品 飞机辅助动力装置的聚四氟乙烯（PTFE）密封件PTFE Seal For Aircraft APU任务是设计一个轻型轴封，减少空间需求，以取代原来的飞机辅助动力装置（APU）设计的机械端面密封。
The task was to design a lightweight shaft seal with reduced space requirements to replace the mechanical face seal that was designed into the original aircraft auxiliary power unit (APU.) 工况 电机转子阻尼器轴承 Rotor Damper Bearing军用飞机应用中的工程要求总是严格的。当高速飞机在几分钟内通过不同的大气条件或在很长一段时间内保持这种状态。
Engineering requirements in military aircraft applications are always rigorous. This is especially so when high-speed aircraft pass through different atmospheric conditions in a matter of minutes or remain in them for very long periods of time.
工程设计团队采用了创新方法。为了减少摩擦和磨损，用HiMod924聚合物轴承取代一些有色金属部件，减少金属之间的接触。
The engineering design team took an innovative approach. To reduce friction and wear, some nonferrous metal parts were replaced with HiMod 924 polymer bearings, and the elimination of metal-to-metal contact was achieved. HiMod轴承可以更好地承受如此严苛的负载和高振动条件。
HiMod bearings could better withstand such demanding load and high vibration conditions. 工况 产品 适用于高真空快速断开工况的密封件 Seal For High Vacuum Quick Disconnect对于这个空间站应用，控制泄漏至关重要。 真空和压力与温度范围和沟槽设计相结合，使该应用具有挑战性。
For this space station application, leakage control was absolutely vital. The vacuum and pressure combined with the temperature range and gland design made this application challenging. 通过选择合适的夹套材料和弹簧负载，该密封件提供了在空间站中使用所需的可靠性和密封性。 With the proper choices of jacket material and spring load this seal provided both the reliability and sealability required for use in the space station. 产品 适合航空测试台的润滑型聚四氟乙烯密封件 Smooth-Running PTFE Seals For Airframe Test Rig用于C17运输机的测试台涉及安装在机身和支撑结构之间的多个液压缸。循环中长的行程发生在模拟飞机机翼上的2.5g向下载荷期间。
A test rig for the C17 transport plane involved numerous hydraulic cylinders mounted between the airframe and support structure.
