Slurry Couplings how to find the center

Slurry Couplings how to find the center ?       

Slurry Couplings looking to find the center is based on the coupling shaft center. Often called to the wheel alignment . Because the pump is a motor driven mechanical or other prime mover , so the minimum requirement is that the two shafts associated with axis coincide, so that it can run smoothly , no vibration.     How can the two- axis coincides with the axis of it ?     

The right position (a) is not before the axis of the codes , then the associated pumping mouth exists , the value of b; motor shaft , and a low , low value of Δh, the axis in order to make the two axes coincide, to the following adjustments:     

1 Frst eliminate the coupling height . To this end the motor shaft should paving Δh, after paving conditions as (b) shows . Then the front and rear bearing A bearing B should also be added under the seat cushion Δh.     

2 . Eliminate coupling mouth . This could be an increase in the different thickness shim A B bearing respectively . B plus pad holder to be thicker than the A ( after the change increases the coupling should ensure that the gasket in the height direction does not occur ) .

How to adjust it? Go through calculations. Pay attention to what matters assembly filler ?     Assembly filler should note the following matters :     

1 Packing specifications to the right, with the working fluid performance to adapt properly to meet the size requirements . If packing too small, although the packing gland screw very tight,slurry pump manufacturer but often ineffective seal effect.     

2 Filler joints should be staggered 90-180 Note that each must be a full circle after circle packing installed in the stuffing box , not a shortage .     

3 Encountered the stuffing box is oval , you can add some larger side filler wire is shown in Figure 4-20 atrium . If not , the following situations may occur . I.e. the smaller side has a very tight compression , while it is still a gap larger , then easy to leak from the larger side or smoke from the smaller side.     

4 When applying filler, filler ring to align to the outlet . Some large pump packing rings , often an easy out, then you can put into a modular integral packing ring packing ring , proved very good. Combined packing ring is shown in Figure 4-22 , is a body filler , which is only a four-point contact with the outer packing box , which is not easy to jam , with little friction . 2 is a gear ring , thin ( 3 a 4 mm ) , it is easy to take out .     

5 After the filler is tight , the gland is surrounded by a gap to be equal. Some Slurry, the gap between b and shaft packing gland is small , it is best to use a feeler gauge to measure what to avoid gland and shaft friction.
