摘要
对于超高压往复式压缩机,其填料密封的失效是化工企业设备维护需要面对的一个重要问题。从填料密封原理入手,介绍了常见的密封失效在填料函、填料环和柱塞上的表现形式,分析了填料密封的失效原因,并从设计、安装、维护和操作等几方面提出了预防填料密封失效的措施。
The failure of the packing seal of the ultrahigh pressure reciprocating compressor is a crucial problem for the equipment maintenance to the chemical enterprises. According to the principle of the packing seal,the expression forms of the common seal failure in the stuffing box, packing ring and plunger are introduced and the reasons are analyzed. Furthermore, the countermeasures to avoid the failure of the packing seal are presented from the aspects of design, installation, maintenance and operation.
