英国Classic过滤器公司--安装不锈钢过滤器时如何固定密封

安装不锈钢过滤器时如何固定密封
How to fit seals when installing a stainless steel filter element

常常有用户问我们为什么在使用不锈钢滤芯时需要密封。因为我们的5层不锈钢滤芯是烧结在一起形成一个坚固结构的滤芯,不像可替换滤芯,不能通过轴向挤压可以密封住。
We are often asked why seals are needed on our 
stainless steel filter elements. Because the 5-layer filter elements are sintered together it forms a rigid structure and unlike the disposable filter elements they cannot be sealed by axial compression.
这类密封可以在很多型号里使用,可参见英国Classic过滤器公司的数据资料。最普通的密封为平面Viton密封或机制的PTFE密封。
The seals are available in a number of types and details can be found in the data sheet 
here. The most common types are a flat Viton seals and machined PTFE seals.
平面密封类型--Viton、EPDM和腈  
Flat Seals – Viton, EPDM and Nitrile
这类平面密封件安装时必须位于过滤器外壳头部嵌块和滤芯固定位上。要小心将密封正确安装到位,此处覆盖了滤芯的尾部。滤芯固定位拧到支柱上,密封件被挤压形成密封。
These flat seals must be located onto the filter housing and element retainer as the filter element is installed. A little care must be taken to ensure the seal is in position correctly and it covers the end of the filter element. Then the element retainer is screwed onto the tie rod the seals are compressed to form a seal.

高温及PTFE密封
High Temperature and PTFE Seals

这种密封件机制而成形成固态棒件,为L形样式,位于滤芯端部,安装滤芯时需要确保定位好。
These seal types are machined form a solid bar stock into a L-shape section and locate on the ends of the filter element to help keep them in position as the filter element is installed.
