The loading plate includes rectangular block, runs through on the rectangular block and is machined with mate with threaded holes, the mate with threaded holes
Be engaged with threaded mandrel, form screw-driven, be symmetrically installed with two pieces of bearing plates in the side of rectangular block, the bearing plate with
The mating groove of ear connecting plate is engaged, through through hole is machined with the bearing plate, the through hole is engaged with bolt.
The position of first screwed hole and the second screwed hole is corresponding with the position of centrifugal pump packing upper screwed hole.
The utility model has the advantages that:
1st, when in use by the way that by the first semicircular ring and the second semicircular ring retaining ring, on centrifugal pump shaft, subdivision line keeps water
It is flat, then loading plate is buckled on the otic placode of point semicircular ring respectively, both are connected together by bolt, adjustment threaded mandrel position
Put, it is vertical with pump shaft, two threaded mandrels are screwed in the screwed hole on stuffing-box clockwise, are then screwed into interior six clockwise
Angle tapping screw, make screw submerge first layer packing effective depth it is consistent, and exposed dividing the screw length outside semicircular ring
Unanimously, threaded mandrel is unclamped counterclockwise, one layer of steel plate of lid on stuffing-box screwed hole, continues synchronous rotary screw thread top clockwise
Bar, first layer packing is slowly taken out of by threaded mandrel, similarly, three-layer disc root below can be removed successively.
2nd, above-mentioned provision for disengagement improves centrifugal pump packing disassembly efficiency, reduces the labor intensity of operating personnel.
