In the process of reaming or boring, apart from the special provisions in factory, does not allow any work that may affect the coupling Centre, such as irrigation, to cylinder connections to flood the condenser pipes and so on. Well boring, hinge bolt hole flange with coupling of vertical, not oblique. Mounting bolts should be added lubricants, typing gently with a small hammer, not too loose or too tight, packed the bolts with the corresponding seal screw hole should be marked. coupling reamed and pairings is close to the diameter of bolt bearing good hinge holes, dressed with a good two coupling bolts before you can move the rotor, boringreaming hole in turn. Coupling bolts must be tight coupling is symmetrical diameter, in boring, reaming, two bolts out. Well boring, hinge bolt hole flange with coupling of vertical, not oblique. Due to the coupling bolts in accordance with hinge holes corresponding to the diameter of the screw holes one by one after processing, processing back bolt installation location cannot be changed, so according to bolt after the actual weight difference of nut and lock washer to match. General requirements for coupling two symmetrical diameter bolt, nut and lock washer39。s total weight difference should not be greater than 10 g and knocks stamped mark. (See Figure 18) The coupling bolts apply lubricant, and then gently with copper home, not too loose or too tight. Bolt Assembly is finished, symmetrical tightening all bolts to 30%, 50%, 70%, 100% force, and check the coupling flutter and before connecting the circle gradually changes its value should be less than . Tightening torque of the coupling bolts shall ply with the technical requirements manufacturers drawings, with a dynamometric wrench or log tension tools. Three wheel rotor swing test coupling connections should be checked: taking leave,
