Abstract
The utility model relates to a novel stuffing sealing device. The novel stuffing sealing device comprises a stuffing box, end rings, stuffing and a stuffing gland, wherein the front inner wall and the back inner wall of the stuffing box are connected with the front end ring and the back end ring; an injection hole is formed in the upper end of the stuffing box; and the back wall of the back end ring is connected with the stuffing gland. The novel stuffing sealing device has a simple structure, a good sealing effect and long service life, does not wear pumps, can be repaired and maintained on line, and is low in cost.
Description
Technical field
The utility model relates to a kind of new packing seal arrangement.
Background technique
The application of pump is very extensive, and its running shaft is parts crucial in the pump with sealing.In the working procedure of centrifugal pump, because of pump shaft, the impeller of centrifugal pump moves, and pump case is static.Like this, have the annular space at impeller gland and the static pump case inwall of rotation, high-pressure liquid just thus the gap flow out from impeller; Cause the volumetric efficiency of pump to reduce, gland seal device commonly used has 2 kinds of packing seal and mechanical seals, and the gland sealed shortcoming is that maintenance load is big; The loss of power is also bigger, and because it always has certain leakage, so be not suitable for process of conveying inflammable, explosive, poisonous and precious liquid; Mechanical sealing mechanism is very complicated; Be again annular element, during installation technical requirements very high, cost is high.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, good sealing effect, long service life, the new packing seal arrangement that cost is low.
The technological scheme of the utility model is:
The new packing seal arrangement comprises stuffing box, end ring, filler, Gland, end ring and back end ring before the front and back inwall of stuffing box connects respectively, and the upper end of stuffing box is provided with hand-hole, the rear wall bonding pad gland of back end ring.
On the said hand-hole valve is set.
Said stuffing box is connected through bolt with Gland.
The utility model is simple in structure, and good sealing effect does not have wearing and tearing to pump, and long service life can onlinely be repaired, keep in repair, and cost is low.
