How to assemble the coupling?

Clean the parts before installing the coupling, and wipe the oil on the parts after cleaning. The couplings prepared for operation in a short time can be coated with turbine oil or oil on the surface of parts after drying to prevent rust. For the coupling that needs to be used for a long time, it should be coated with anti-rust oil. For the use of coupling in high-speed rotating machinery, generally in the factory have done dynamic balance experiment, dynamic balance experiment after passing the mark between the parts with each other. It is important that the assembly be made according to the mark given by the manufacturer. If not according to the mark arbitrary assembly, it is likely to produce the vibration of the unit due to the poor dynamic balance of the coupling. In addition, the connecting bolt on the flange of this kind of coupling is load-bearing, so that the connecting bolt on each coupling can achieve the same weight basis. Such as large centrifugal compressor with the tooth coupling, the weight difference between the connecting bolts used is generally less than 0.05g. Therefore, the bolts between the coupling can not be arbitrarily exchanged, if you want to replace the coupling of a bolt, it must make its weight and the original weight of the bolt. In addition, when tightening the connecting bolt of the coupling, it should be symmetrical and gradually tightened, so that the locking force on each connecting bolt is consistent, so that the coupling will not skew after assembly because of the uneven force of the bolts. If possible, torque wrench can be adopted. Our company specializes in the production of plum couplings

For the rigid movable coupling, after assembly should review whether the rigid movable parts of the coupling can move a small amount, there is no jam phenomenon. All kinds of couplings should be turned after assembly to see whether the rotation is good. In short, the accurate installation of the coupling can improve the operation of the equipment, reduce the vibration of the equipment, and extend the service life of the coupling.
