在石油、化工生产中,机械密封的应用愈来愈广泛。机械密封摩擦付的材料是影响密封使用寿命的主要因素之一,选择既耐腐蚀、耐磨,又有足够机械强度的材料作摩擦付,采用合理的结构,再加上严格精确地安装,一般都会保证足够高的使用寿命。合理的结构,严格精确地安装两项,一般不难达到,而在种类繁多的材料中选择恰当合用的材料作为摩擦付,就显得重要了。基于上述,我们曾用陶瓷和填充玻璃粉 In petroleum, chemical production, the application of mechanical seals more and more widely. Mechanical seal friction material is the impact of sealing service life of one of the main factors, choose both corrosion-resistant, wear-resistant, but also sufficient mechanical strength of the material for friction pay, the use of reasonable structure, coupled with strict and accurate installation, the general Will ensure a sufficiently high life. Reasonable structure, rigorous and accurate installation of two, generally not difficult to achieve, and in a wide range of materials, select the appropriate combination of materials as friction pay, it is important. Based on the above, we have used ceramic and filled glass powder
