Abstract
The utility model discloses a split stuffing box stuffing structure which comprises a cylindrical stuffing box which is formed by a left semi-circle sleeve and a right semi-circle sleeve in a combined mode, wherein the left semi-circle sleeve and the right semi-circle sleeve are completely same. A cavity inside the stuffing box is used for containing packing. A fixed flange is arranged at the outer end of each semi-circle sleeve. A shaft hole is formed in the inner end of each semi-circle sleeve. The outer end of the stuffing box is sleeved with a flange cover for tightly pressing the packing. The flange cover is connected with a pump body through a fastening bolt. The structure overcomes the original defect that traditional stuffing is directly installed between the pump body and a pump shaft. Meanwhile, due to the fact that the stuffing box is designed to be of a left-right split separable structure, rapid and convenient conditions are provided for taking out and installing the packing, and the working efficiency and the working quality are greatly improved.
Description
Technical field
The utility model relates to a kind of sealing configuration of pump, is specially a kind of left and right split type stuffing box structure.
Background technique
Use in the centrifugal pump of packing filling at present, its stuffing box is directly to make on the pump housing, and stuffing box is that a structure on the pump housing can not be separated in other words.When packing in the centrifugal pump stuffing box is aging when needing the whole packing of displacement, must with special tool packing that all are to be replaced one by one hook go out.Because it is very tight that aging packing is combined with pump shaft, be difficult to the complete taking-up of whole piece packing.Need equally when replacing new packing one by one with packing one by one order be pressed in the stuffing box, repeatedly after the repetitive operation, inevitably can make new packing just not be subject to partial destruction before using.Because existing centrifugal pump stuffing box designs drawback, removing old packing all needs each bar packing is operated one by one with the new packing of installation, can not once all packings once be taken out or installation in position in a word.Not only repeatedly repetitive operation labor intensity is large, and takes out with the installation packing and can not guarantee operation quality.
The model utility content
The purpose of this utility model provides a kind of new packing letter device.Because two component combinations become complete stuffing box about having adopted, freely separate with the pump housing so can realize stuffing box, simultaneously, remove old packing and all whole packing bars can be taken out or installation in position as one piece with the new packing of installation, time saving and energy saving.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of split type gland packing structure, it is characterized in that, comprise by left and right two tubular stuffing boxes that identical half round bush combines, cavity in the described stuffing box is used for holding packing, and the outer end at described half round bush is provided with fastening flange, and the inner is provided with axis hole; Described stuffing box outer end is nested with a blind flange that compresses packing, and described blind flange is connected with the pump housing by clamping bolt.
Between the pump housing and cylinder, be provided with the O RunddichtringO.
Described blind flange is the inboard projection that an insertion stuffing box cavity is arranged.
The utility model has the advantage of: this kind structural change in the past conventional filler be directly installed on drawback between the pump housing and the pump shaft, left and right sides split type separable structure will be designed to simultaneously between the stuffing box, provide convenient condition for taking out with packing is installed, greatly increase work efficiency and workmanship.
Description of drawings
Accompanying drawing 1 is the utility model disassembly and assembly structure schematic diagram.
Accompanying drawing 2 is that stuffing box cooperates schematic diagram in the utility model.
Embodiment
Be elaborated below in conjunction with Fig. 1 to Fig. 2
A kind of split type gland packing structure and replacement method, it comprise among Fig. 2 about two and half round bushes, two and half round bushes 6 can be combined to form a cylinder stuffing box.And the outer end at half round bush is provided with fastening flange, and flange is provided with flange hole, is used for connecting with the pump housing.The inner is provided with axis hole, allows that pump shaft passes through.
After its correct installation as shown in Figure 1, wherein half round bush 6 compresses O RunddichtringO 7 and be positioned on the pump housing 8 by six square bolts 5 in ten, form stuffing box, be cup-shaped, just form like this circular space that holds packing 4 between split type stuffing box and the pump shaft 9.Packing 4 order that will be fit to again specification is packed into (packing 4 otch arranged direction each other is with reference to the packing instruction for installation) in the stuffing box, and is fixing and be pressed on the pump housing 8 by nut 1, stud bolt 2 and packing filling gland 3, finishes whole installation.
Because the utility model has adopted left and right split type structure, only needs split type stuffing box integral body is involved and all waste and old packing bar connections can be gone out when needs are all changed the packing of inefficacy, the time saving and energy saving failure disc velamen that can guarantee is again removed clean.When simultaneously new packing being installed, also can all packing bars once being pressed into by above-mentioned opposite operating process and being in place, protect undoubtedly new packing that the damage of mechanical force is not installed.Compress O type circle in the stuffing box undercut by six square bolts in ten, realize that stuffing box connects with the pump housing and seal.The cylindrical cavity that left and right two parts combine provides the space that holds the packing bar.Renewal process is specific as follows:
Step 1 unloads blind flange on the pump housing;
Step 2 will be taken off on the two and half round bush self-pumping bodies, and then packing is scattered out automatically;
Step 3 is fixed on two and half round bushes on the pump housing, and new packing is installed in half round bush;
Step 4 is fixed on blind flange on the pump housing.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; the relevant technical staff in the field all should expand as in the determined protection domain of the utility model claims various distortion of the present utility model and improvement.
