GDL/CDL多级高压增压泵总成:雷竞技官网最新版

　　When the GDL/CDL multi-stage pump is assembled, all threads of bolts and nuts must be coated with a layer of lead powder oil. After assembling the final stage impeller, the axial distance between the hub and the two ends of the balance disc hub must be measured, and the axial dimension of the retaining sleeve in between should be determined according to this axial distance. The sum of the axial gap between the retaining sleeve and the impeller hub, the retaining sleeve and the balance disc hub is 0.30~0.50mm. Because in the initial stage of GDL/CDL multi-stage pumps, the parts on the impeller and other shafts are first affected by the medium with higher temperature and temperature, and the shaft is affected by heat. After that, their expansion has a time difference. The axial gap of 0.3~0.5mm is left to prevent the impeller, balance disk, etc. from expanding first and collapsing each other, resulting in greater tensile stress on the pump shaft.

长干螺栓只能在装配开始时稍微拧紧。待整个多级泵现场安装到位后，根据记录数据拧紧长杆螺栓。雷竞技官网最新版拧紧时必须对称操作，否则会造成型材之间密封性差。当GDL/CDL高压增压泵装有平衡板座的压力环时，需要在GDL/CDL的上侧与雷竞技官网最新版平衡水管连接处对齐一个间隙。否则，平衡水管堵塞，整个轴向平衡装置失效。联轴器的对准方法与单级离心泵联轴器的对准方法相同。雷竞技官网最新版
