Proper hose selection is critical to realize a safe hydraulic system. The first step in having a safe hydraulic system is selecting components that meet the needs. Compromises in hose selection may create situations of danger, as well as affect the performance and durability of the system. The choice may work for the short run, but may not be a good long-term decision. This guide uses the STAMPED process.STAMPEDis an acronym that stands for the 7 major information areas required to provide a quality hose assembly, and in this post, we’re talkingT为了温度.
T皇帝：输送的流体和环境条件的温度
必须考虑两个温度区域：流体温度和环境温度。所选的软管必须能够承受系统看到的最低和最高温度。在热歧管附近的路由时，必须小心，并且在极端情况下可能建议使用隔热罩。
- 最大间歇环境温度：使用橡胶内管和/或覆盖的软管构造在暴露于极高或冷的情况下，性质可能会发生显着变化。在暴露于此类条件时，这可能需要一些软管的额定压力。
- Fluid Temperature:The fluid temperature is the temperature of fluid being conveyed inside of the hose during operation.
- Ambient Temperature:The ambient temperature is the temperature of the environment to which the hose assembly is exposed.
- Maximum Temperature:The maximum temperature is the highest temperature to which the fluid or environment may reach. This temperature is typically short in duration and occurs under extreme operating conditions. The hose selected for an application should be rated at or above the maximum ambient and maximum fluid temperature.
- Minimum Temperature:最低温度是软管组件暴露到的最低温度。对于液压系统，这是基于最低环境温度的。软管应在可能暴露于组件的最低环境温度下进行评级。
- 随着温度的升高，最大组装工作压力将减小。
软管组件的温度降低因子
温度directly affects maximum allowable working pressure. Most manufacturers rate maximum operating pressures at an ambient temperature of 70 degrees F. If a hose is to be considered for use in an application that exceeds this ambient temperature, consult manufacturer for any pressure derating of the hose assembly.
