Centrifugal-pump sealing filling taking-feeding device

The utility model relates to a centrifugal pump sealing filling material removal and adding device for removing or adding the centrifugal pump sealing filling material in a large-scale multi-grade high-pressure centrifugal injection pump. The utility model is characterized in that the pressing cover is assembled with the righting sleeve; the pressing cover is provided with a top cone and a plurality of guide holes which are separately arranged on a plurality of fixed bolts of the pump body; the top cone is moveably connected with the pressing cover by the thread holes of the top cone; the righting sleeve is arranged in the sealing stuffing box, is uniformly provided with a plurality of faucet thread holes, and is provided with a built-in concave bolt whose lower part is connected with a spiral hook; the externally connected convex bolt is screwed into the righting sleeve to make the filling material enter in and the convex bolt is screwed out of the righting sleeve to make the filling material back to the hidden chamber; the sealing filling can be blocked into the ring positioning trough formed between the pressing cover and the righting sleeve; the length and the cutting angles of the sealing filling material can be measured and positioned. The utility model has the benefits of that good sealing effect of the shaft end of the centrifugal pump is reached, reliable base guarantees are provided, meanwhile, the work efficiency is raised.
