Technical Field

The invention relates to the technical field of paper pulp pumps, in particular to a high-sealing paper pulp pump.

Background

Most pulp pumps in the existing market mostly utilize a sealing ring or a sealing part to seal a pump shaft, and because the pump shaft is smooth, if the sealing part is slightly deformed after long-time use, a gap is easily generated between the sealing part and the pump shaft, and the sealing effect is lost, so that the pulp pump with high sealing property is provided aiming at the problems.

Disclosure of Invention

The invention aims to provide a high-sealing pulp pump, which is simple in structure, easy to construct and remarkable in sealing effect, and solves the problems in the background art by arranging two groups of convex rings on a pump shaft, clamping the convex rings on two sides of a bearing plate, and arranging grooves for fitting the convex rings on sealing rings arranged on two sides of the bearing plate.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides a high leakproofness pulp pump, includes pump shaft and pump case, the fixed bearing box that is provided with of pump case rear side, the cavity internal fixation of bearing box inside is provided with the bearing, the bearing box right side is provided with the pump cover, both ends are all fixed on the pump case through set screw about the pump cover, the fixed board of accepting that is provided with on the inner wall of pump case left side, the pump shaft is from the right side to left run through in pump cover, bearing, pump case and the board of accepting stretch into the pump body, all be provided with the bulge loop in accepting board both sides on the pump shaft, it is provided with the sealing ring to accept board both sides and be located.

Preferably, the convex ring is of an annular structure with an outer tip and an inner width, the convex ring is fixedly welded on the pump shaft, and the setting height of the convex ring is 5-8 mm.

Preferably, the inner sides of the sealing rings are provided with grooves for attaching the convex rings, and the sealing rings are fixedly arranged on the inner walls of two sides of the bearing plate through-penetrating hole.

Preferably, the bearing plate is welded to the pump casing seamlessly.

Compared with the prior art, the invention has the beneficial effects that: through set up two sets of bulge loops on the pump shaft, this bulge loop card is accepted the board both sides, and the sealing ring of accepting the board both sides setting is provided with the recess that has the laminating bulge loop, can realize effectual sealedly, this simple structure, easy construction, and sealed effect is showing, suitable using widely.
