通风机是矿井的心脏,及时抢修通风机主轴是矿井安全生产的保证。局机电处的实践说明,采用氧─乙炔焰金属粉末喷涂,轴基体组织不发生改变,轴体强度不变弱,工艺灵活,可以现场施工。这在安全上、经济上、工期上都优于更换主轴。 一、修复主轴,采用如下的工艺和技术 1、喷涂前的准备工作 现场修复大型设备轴类磨损,必须做好施工前的准备工作。
Ventilator is the heart of the mine, timely repair fan shaft is the guarantee of mine safety. Bureau of Electrical and Mechanical Services Department of Practice shows that the use of oxygen ─ acetylene flame metal powder coating, the shaft matrix structure does not change, the shaft body strength is not weakening, flexible process, you can on-site construction. This is safer, more economical and more constructive than replacement. First, repair the spindle, the use of the following processes and technologies 1, the preparation before spraying Repair of large-scale equipment on-site shaft wear, must be prepared before construction.
