How to choose the size of gland type double flange force transfer joints
For the gland type double flange force transmission joint applied on the pipeline, the dynamic balance test is generally done in the manufacturing factory, and the mark of the mutual coordination orientation between the parts is drawn after the dynamic balance test is qualified. When assembling, it must be assembled according to the mark given by the manufacturer, which is very important. If assembled arbitrarily without marking, it is likely to occur due to the phenomenon of vibration of the unit caused by the bad dynamic balance of the gland-type double-flange force transfer joint.
 
In addition, the connecting bolts on the flange of this kind of gland type double flange force transmission joint are load-bearing, so that the connecting bolts on each gland type double flange force transmission joint can achieve the same weight. Such as large centrifugal compressor on the cover type double flange transmission joint, the connection bolt used between each other's weight difference is generally less than 0.05 g. Therefore, cover type double flange transmission joints between the bolts can not be arbitrarily interchanged.
 
If you want to replace one of the connecting bolts of the gland-type double-flange force transfer joint, you must make its weight the same as the weight of the original connecting bolts. In addition, when tightening the connecting bolts of the gland-type double-flange force transfer joint, they should be tightened symmetrically and gradually.
 
So that the locking force on each connecting bolt is basically the same, so that the uneven force on each bolt will not cause the gland type double flange force transmission joint to be skewed after assembly, and a torque wrench can be used if there are conditions. For the gland type double flange force transmission joint, after assembly, should check the rigid removable parts of the gland type double flange force transmission joint can move a small amount, there is no jamming phenomenon.
