汽轮机找中心是大修中一项极为重要的工作。N125汽轮机是双缸双排汽凝汽式结构,采用两转子三轴承支承。我厂4台N125汽机从投产至今已进行了多次大修,首次大修仍沿用小容量单转子汽轮机找中心的传统工序:即隔板洼窝找中心是按修前真轴位置(油挡洼窝中心)进行调整的。隔板找中心后调整汽封间隙、动静间隙、推力间隙;扣缸后再进行转子靠背轮找中心工作。 Turbine finding a center is an extremely important task in overhaul. The N125 turbine is a twin-cylinder double-row steam condensing steam turbine with two rotor triple bearings. Our factory has already carried out several overhauls since its commissioning. The first overhaul still follows the traditional procedure of finding the center of a small capacity single-rotor steam turbine: that is, the center of the baffle is located according to the true axis position before repair Center) to adjust. After the center of separator to adjust the seal gap, static and dynamic clearance, thrust gap; buckle cylinder rotor center back to find the work center.
