化工生产中常用各种压缩机对原料气加压。如何有效地控制轴封泄漏,是增加机台出率,延长工作寿命,减少维修费用,保证设备稳定运转的关键。以下介绍一些压缩机有效密封的结构、材料选择原则和设计要点。(一)密封圈的结构化肥厂中使用的氢氮压缩机、氨压缩机、循环机、空压机等均为往复式压缩机,其往复运动轴的密封型式可分为机械压紧式和自紧密封式两大类。在机械压紧密封中,是籍填料压盖
Various types of compressors are commonly used in chemical production to pressurize the feed gas. How to effectively control the leakage of the shaft seal is the key to increase the machine output rate, extend the working life, reduce the maintenance cost and ensure the stable operation of the equipment. The following describes some of the effective structure of the compressor seal, material selection principles and design points. (A) the structure of the seal The hydrogen-nitrogen compressor, ammonia compressor, circulating machine, air compressor, etc. are reciprocating compressors used in fertilizer plants, the reciprocating shaft seal type can be divided into mechanical compression and Tight sealed two categories. In the mechanical compression seal, is based on packing gland
