在高温、低温、高压、强腐蚀性领域仪表的泄漏与密封已越来越被人们关注,为了确保仪表长期运行,合理选用密封材料是杜绝泄漏的关键所在,仪表在安装、使用过程中有下面几个方面要引起足够重视:1.密封材料的最高、最低使用温度及密封材料在使用过程中其物理力学及热物理性能要具有很好的稳定性。2.提高密封材料的减摩性和耐磨性。应根据具体情况选择减少磨损、不易引起形变的材料。3.与密封介质的相容性不容忽视,首先应要求密封材料与密封
In the field of high temperature, low temperature, high pressure, strong corrosive instrument leakage and sealing has been more and more people’s attention, in order to ensure the long-term operation of the instrument, the rational use of sealing material is to prevent leakage is the key instrument in the installation, use the following process Several aspects to be paid enough attention to: 1. Sealing materials, the highest temperature and sealing materials in the use of its physical and thermal physical properties to have good stability. 2. Improve the anti-friction and wear resistance of the sealing material. Should be based on the specific circumstances to choose to reduce wear and tear, easy to cause deformation of the material. 3. Compatibility with the sealing medium can not be ignored, first of all should require sealing materials and seals
