Description
Technical field
The utility model is related to a kind of sealing device, more particularly to a kind of pump stuffing box structure.
Background technology
Water pump stuffing box also known as stuffing box are pierced by the place of pump case mounted on pump shaft.Filler seals, and prevents water from leaking
Go out outside pump and enter with air in pump.Filler is generally wick and asbestos cord, is compressed with gland, and installation seal cage among filler leads to
Water seal cooling tube is crossed, the pressure water in pump case is evenly distributed on filler, plays the role of cooling and lubricating filler and pump shaft.
But in the prior art, due to pump shaft, friction generates heat with filler, and filler generates abrasion and causes stuffing-box
Inner cavity loosens, and can not play the effect of sealing well.
Utility model content
The technical problem to be solved by the present invention is to provide the good pump stuffing-box knots of a kind of automatic impaction, sealing effect
Structure.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of pump stuffing box structure, including stuffing-box body, hold-down mechanism, it is characterised in that：The hold-down mechanism connects
It is connected to the top of stuffing-box body；
The stuffing-box body has hollow structure, and into cavity structure, stuffing-box body is additionally provided with cooling stream at middle part
Road；The one side of the cavity is equipped with step, and seal ring is provided on the step；The internal cavities of the stuffing-box, which are provided with, to be filled out
Material；
The hold-down mechanism includes gland, guiding axis, spring, and one end of the guiding axis is arranged at the upper of stuffing-box body
End, the other end of guiding axis are fixed with fastener；The gland has boss structure, and the boss of gland is sheathed on guiding axis,
Gland is arranged at the inner cavity of stuffing-box body；The spring is arranged at fastener between gland.
Preferably, gap is provided between the boss of the gland and the stuffing-box body, the gap is more than 3 centimetres.
Preferably, the outer diameter of the gland is identical with the interior chamber size of the stuffing-box body.
Preferably, the coolant flow channel is provided with flow-stopping plate.
Preferably, the filler accounts for more than the 60% of the stuffing-box chamber body.
Using above-mentioned technical proposal, since the hold-down mechanism is connected to the top of the main body of stuffing-box；Stuffing-box main body
It is additionally provided with coolant flow channel；So that sealing effect is more preferable, and play good cooling effect.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure, 1- stuffing-box bodies, 2- hold-down mechanisms, 3- guiding axis, 4- springs, 5- glands, 6- fillers, 7- seal rings.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form the restriction to the utility model.This
Outside, technical characteristic involved in each embodiment of the utility model disclosed below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, a kind of pump stuffing box structure, including stuffing-box body 1, hold-down mechanism 2, hold-down mechanism 2 connects
In the top of the body 1 of stuffing-box；
Stuffing-box body 1 has hollow structure, and into cavity structure, stuffing-box body 1 is additionally provided with coolant flow channel at middle part,
Cool down the heat that pump shaft is generated with filler friction；The one side of cavity is equipped with step, and seal ring 7 is provided on step, plays more preferable
Sealing effect；The internal cavities of stuffing-box are provided with filler 6；
Hold-down mechanism 2 includes gland 5, guiding axis 3, spring 4, and one end of guiding axis 3 is arranged at the upper of stuffing-box body 1
End, the other end of guiding axis 3 are fixed with fastener；Gland 5 has boss structure, and the boss of gland 5 is sheathed on guiding axis 3,
Gland 5 is arranged at the inner cavity of stuffing-box body 1；Spring 4 is arranged at fastener between gland 5, when filler 6 occur abrasion can and
When compress prevent pump housing failure.
In addition, gap is provided between the boss of gland 5 and the stuffing-box body 1, gap is more than 3 centimetres, makes compression
There is feeding gap in mechanism 2.
Further, the outer diameter of gland 5 is identical with the interior chamber size of the stuffing-box body 1.
In addition, coolant flow channel is provided with flow-stopping plate.
Further, filler 6 accounts for more than the 60% of 1 inner cavity of stuffing-box main body.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
