Description
Technical field
The utility model relates to a kind of stuffing seal for all kinds of pump shaft.
Background technique
At present, for the stuffing seal of all kinds of pump shaft, comprise fixing fitting seat, the axle sleeve be fixed on pump shaft, the stuffing box gland be placed on outside pump shaft and axle sleeve, stuffing box gland is provided with shoulder hole, stuffing box gland front end outside axle sleeve be provided with band endoporus before packing ring, be provided with the water inlet be connected with front packing ring endoporus in stuffing box gland, in the stuffing box gland on rear side of front packing ring, be provided with filler, on axle sleeve on rear side of filler, cover has pressure ring, and the bolt of more than passes through scyewed joint through pressure ring and fitting seat; This device in use for some time, causes sealability to decline once filler is lax, can by screwing bolts, make pressure ring reach to compress filler, to recover sealing effect; But this structure is owing to can only compress filler from rear end, cause the tightness of filler in stuffing box gland inconsistent, front end is more loose, rear end is tighter, and the axle sleeve friction with rotating, causes the wearing and tearing of rear end filler very fast, then cannot ensure sealability, only have replacing filler, its working life is shorter.
Summary of the invention
The purpose of this utility model is for prior art above shortcomings, provides a kind of stuffing seal of pump shaft, and it effectively can extend the working life of filler, and improves sealing effect, and is convenient to change filler.
For achieving the above object, the stuffing seal of pump shaft of the present utility model, comprise fixing fitting seat, be fixed on the axle sleeve on pump shaft, be placed on the stuffing box gland outside pump shaft and axle sleeve, stuffing box gland is provided with shoulder hole, stuffing box gland front end outside axle sleeve be provided with band endoporus before packing ring, the water inlet be connected with front packing ring endoporus is provided with in stuffing box gland, filler is provided with in stuffing box gland on rear side of front packing ring, on axle sleeve on rear side of filler, cover has pressure ring, the bolt of more than one passes through scyewed joint through pressure ring and fitting seat, it is characterized in that stuffing box gland stage casing slide be located in fitting seat, the rear end of stuffing box gland is provided with the end plate be positioned on rear side of fitting seat, the anti-top fastening bolt of more than one and end plate pass through scyewed joint, the ear end face of fitting seat is withstood in the front end of anti-top fastening bolt.
During use, sealability is caused to decline once filler is lax, not only can by screwing bolts, pressure ring is moved forward from rear end compress filler, and to move after rotating anti-top fastening bolt, making stuffing box gland, by the front packing ring tight filler of side pressure in the past, thus make the tightness of filler in stuffing box gland consistent, the wearing and tearing of front and back ends filler are more even, and wearing and tearing are also comparatively slow, and constantly can compress filler, can ensure sealability, its working life is longer.
As further improvement of the utility model, the hold-down bolt of more than passes through scyewed joint through end plate and fitting seat; After moving on to position after stuffing box gland, screwing hold-down bolt can locate stuffing box gland; As needed to move stuffing box gland afterwards again, unclamp hold-down bolt;
As further improvement of the utility model, the stuffing box gland of axle sleeve front end is provided with annular groove, in annular groove, is provided with sealing gasket; When changing filler, move after stuffing box gland, end in contact before sealing gasket and axle sleeve, can ensure sealing, prevent dielectric leakage in pump, is convenient to change filler;
As further improvement of the utility model, in filler, be provided with the rear packing ring of band endoporus, in stuffing box gland, be provided with the water inlet be connected with rear packing ring endoporus; By injecting flowing medium to two water inlets, medium in a little higher than pump of pressure of flowing medium, can play the effect of pushing off the slag to medium in pump, improves sealing, to its lubrication of filler, can reduce wearing and tearing again; Two packing ring is applicable to the higher operating mode of medium in pump;
In sum, the utility model effectively can extend the working life of filler, and improves sealing effect, and is convenient to change filler.
Accompanying drawing explanation
