氧-乙炔火焰自熔合金粉末喷焊技术,目前不仅已被人们用作易损件的修复再生,而且正被当作产品设计中零件的强化措施。我厂近年来,应用这一新技术在提高石油钻采设备和化工泵零部件的使用寿命,发展新品种方面进行了探索,取得了一定成效。现将在耐久型泥浆泵活塞杆上的喷焊应用,介绍如下:一、工况分析活塞杆是泥浆泵的主要易损件之一(图1)。它在工作中除传递交变的轴向载荷外,还受着悬浮在泥浆
Oxygen-acetylene flame self-fluxing alloy powder spray welding technology, not only has been used as a repair of wearing parts regeneration, and is being used as part of product design strengthening measures. In recent years, our factory has made some achievements in application of this new technology in improving the service life of oil drilling equipment and components of chemical pumps and developing new varieties. Now in the durability of the mud pump piston rod spray welding applications, described below: First, the condition analysis The piston rod is one of the main wearing parts of the mud pump (Figure 1). In addition to delivering alternating axial loads, it is also suspended in the mud
