江苏SKF轴承轴承座抖动诱因

较近，我们收到了客户询问风扇设备江苏SKF轴承的振动的问题。在我们的工作人员调查后，有3个原因：
Recently, we received a customer enquiry about the vibration of fan bearing equipment SKF bearing in Jiangsu. After investigation by our staff, there are 3 reasons:
1。江苏SKF轴承球面垫圈支撑结构不合理。风扇装置采用球面垫圈的支撑方式。在调整轴承座时，更方便，调节量也得到了更好的控制。然而，在汽轮机负荷大、振动大的情况下，由于受力面积小、机组力过大，支承螺纹塑性变形严重，导致机组在高负荷下的运行状态恶化，出现故障。油膜涡动、结构松动等特性以及轴承布什的损坏。
1. The supporting structure of SKF bearing spherical washer in Jiangsu is unreasonable. The fan device is supported by a spherical gasket. When adjusting the bearing seat, it is more convenient and the adjustment quantity is better controlled. However, in the case of large load and large vibration of steam turbine, the plastic deformation of the supporting thread is serious because of the small force area and the large force of the unit, which leads to the deterioration of the operating state of the unit under high load, and the failure occurs. Oil whirling, structural loosening, and bearing Bush damage.
2。在唐山钢厂废弃后，江苏SKF轴承座导向件发生变形和损坏。在工厂运行过程中，振动一直是不稳定的。轴承座、调整螺栓、气缸导轨等金属零件的金属零件有不同的塑性变形或损坏。由于导料材料强度不足，风机安装精度长期下降。
2. After the Tangshan steel mill was abandoned, the guide parts of Jiangsu SKF bearing block were deformed and damaged. In the process of plant operation, vibration is always unstable. Metal parts of bearing parts, adjusting bolts, cylinder guides and other metal parts have different plastic deformation or damage. As the strength of the material is insufficient, the installation accuracy of the fan decreases for a long time.
3。在大修过程中，关键支撑点膨胀间隙的调整是不正确的。松弛是不可靠的，江苏SKF轴承松弛位移是长期造成的，引导更差。使轴系统发生变化，从而使机组振动**标。
3. In the overhaul process, the adjustment of the expansion gap of the key supporting points is not correct. Relaxation is not reliable. The relaxation displacement of SKF bearing in Jiangsu is a long-term result, and the guidance is even worse. Causes the shaft system to change, thus causes the unit vibration to exceed the standard.
即，将软材料放置在轴承盖上并与旋转江苏SKF轴承直接接触将起到密封作用。由于密封件与配合件之间的直接接触，密封件在工作中具有较大的摩擦，并且热量也很大。接触面易产生润滑不良，易磨损，导致密封效果和性能下降。
That is, placing soft material on the bearing cap and directly contacting with the rotating SKF bearing of Jiangsu will play a sealing role. Because of the direct contact between the seal and the mating parts, the seal has greater friction and greater heat in the work. Contact surfaces are prone to poor lubrication and wear, resulting in a reduction in sealing effectiveness and performance.
