Mechanical seals keep the fluid contained within pumps while the internal mechanical components move inside the stationary housing. When mechanical seals fail, the resulting leaks can cause extensive damage to the pump and often leaves large messes that can be significant safety hazards. Besides being a crucial component to a pump running efficiently, it is also the most common culprit of pump downtime.
了解机械密封故障的原因可以帮助客户进行预防性维护，并最终帮助其泵的使用寿命。这是机械密封失败的一些最常见原因：
使用错误的密封
它是非常重要的,你是美国的海豹ing is correct for the application. Numerous factors like pump specifications, temperature, fluid viscosity, and chemical aspects of the fluid are all determinants in which mechanical seal is right for the job. Even experienced engineers can sometimes miss certain aspects which result in seals that do not meet the needs of the application. The best way to ensure you are using the correct seals is to consult with pump specialists that can take a look at the entire application and recommend seals based on all contributing factors.
干燥泵
当泵没有足够的液体运行时，称为“干燥”。在正常运行期间，要处理的流体将填充泵内的流动空间，有助于冷却和润滑机械密封组件，相互接触。没有这种液体，缺乏冷却和润滑会导致内部组件过热并开始失败。当泵干燥时，密封件可能会在短短30秒内过热和分解。
振动
There are a variety of factors that can lead to excessive vibration in the pump, including improper installation, misalignment and cavitation. While mechanical seals aren’t a contributing factor to vibration, they will suffer along with other internal components when pump vibration exceeds acceptable levels.
Human Error
泵的任何操作在其预期规格和使用外部都可能损坏其组件并承担故障的风险，包括机械密封。安装不当，启动不当以及缺乏维护可能会磨损密封，并最终导致其失败。在安装和引入污垢，油或任何其他磨料材料之前，密封的不当行为也会造成损坏，随着泵的运行而变得更糟。
