Abstract
The utility model designs a novel middle-open type stuffing box for a double-suction pump, which comprises a stuffing gland, a pump cover, a pump body, a pump shaft, stuffing and a stuffing flushing ring, and is characterized in that: the outside of pump cover is provided with open stuffing box in, and the outside of open stuffing box is provided with gland, and the mid portion in open stuffing box is provided with the filler and washes the ring, is filled with the filler in filler washing ring both sides, and filler washing ring intercommunication sets up the sparge water interface on open stuffing box in. The utility model has the advantages of simple and compact structure, convenient use and maintenance, more convenient installation, use, maintenance and the like compared with the traditional structure, and can directly loosen the fasteners of the pump body, the pump cover and the middle-open type stuffing box when the filler is replaced, withdraw from the middle-open type stuffing box, open the fasteners, disassemble all the filler without disassembling the pump body and the pump cover, thereby being very convenient, time-saving and labor-saving. And the structure is very reliable, so that the structure is a novel structure worthy of wide application.
Description
Technical Field
The utility model relates to a stuffing box for a pump, in particular to a novel middle-open type stuffing box for a double-suction pump.
Background
The conventional packing seal component (fig. 1) mainly comprises a packing gland 20, a flushing water pipe 21, a pump cover seal cavity 22, a pump body seal cavity 23, packing 24, a packing flushing ring 25 and a fastener 26. The working principle is as follows: the packing is compressed by screwing the fastener on the packing gland, so that the packing is tightly embraced on the rotating shaft or the shaft sleeve, the flushing water part provides flushing water, the flushing water is injected into the packing flushing ring to disperse water to the periphery, and the packing embraced on the rotating shaft or the shaft sleeve plays the roles of lubricating agent and cooling, so that a sealing system is achieved and the sealing system can be used for a sealing part between a medium end and an atmosphere end. The double suction pump in the prior market is used for sealing with the structure, the structure is reliable in sealing, but the double suction pump has the defects that the filler is inconvenient to replace, a fastening piece on the filler gland is required to be opened when the filler is replaced, the filler gland is withdrawn, and the filler is taken out one by one for replacement.
Disclosure of Invention
The utility model aims to design a novel middle-open type stuffing box for a double-suction pump, which can improve the defects of the traditional stuffing sealing structure and is simpler, quicker and more reliable to use. The utility model designs a novel middle-open type stuffing box for a double-suction pump, which comprises a stuffing gland, a pump cover, a pump body, a pump shaft, stuffing and a stuffing flushing ring, and is characterized in that: the outside of pump cover is provided with open stuffing box in, and the outside of open stuffing box is provided with gland, and the mid portion in open stuffing box is provided with the filler and washes the ring, is filled with the filler in filler washing ring both sides, and filler washing ring intercommunication sets up the sparge water interface on open stuffing box in. The middle-open type stuffing box consists of an upper stuffing box and a lower stuffing box, the upper stuffing box and the lower stuffing box are connected by a fastener, and a flushing water interface is arranged on the upper stuffing box. The middle-open stuffing box is connected with the pump body through a fastener. The packing gland is connected with the middle-open type packing box through a fastener. The utility model has the advantages of simple and compact structure, convenient use and maintenance, more convenient installation, use, maintenance and the like compared with the traditional structure, and can directly loosen the fasteners of the pump body, the pump cover and the middle-open type stuffing box when the filler is replaced, withdraw from the middle-open type stuffing box, open the fasteners, disassemble all the filler without disassembling the pump body and the pump cover, thereby being very convenient, time-saving and labor-saving. And the structure is very reliable, so that the structure is a novel structure worthy of wide application.

FIG. 1 is a cross-sectional view of a prior art structure.
FIG. 2 is a structural cross-sectional view of the present invention.
Fig. 3 is a schematic end view of the structure of the middle open stuffing box of the present invention.
Detailed Description
In the figure, the novel middle-open stuffing box for the double-suction pump comprises a stuffing gland 1, a pump cover 2, a pump body 3, a pump shaft 4, stuffing 5 and a stuffing flushing ring 6, and is characterized in that: the outside of pump cover is provided with well open type stuffing box 7, is provided with gland in the outside of well open type stuffing box, and the mid portion in well open type stuffing box is provided with the filler and washes the ring, is filled with the filler in filler washing ring both sides, and filler washes the ring intercommunication and sets up the sparge water interface 8 on well open type stuffing box. The middle-open stuffing box is composed of an upper stuffing box 9 and a lower stuffing box 10, the upper stuffing box and the lower stuffing box are connected through a fastener 11, and a flushing water interface is arranged on the upper stuffing box. The centre-opening stuffing box is connected to the pump body by fasteners 12. The gland is connected to the centre-opening stuffing box by fasteners 13.
Compared with the prior art structure, the length of the sealing cavity of the pump body and the pump cover is shortened, the added middle-open type stuffing box replaces the original sealing cavity on the pump body and the pump cover, and the middle-open type stuffing box structure is of a middle-open type structure and is formed by half-and-half combination of an upper stuffing box and a lower stuffing box through fasteners. When the filler is replaced, the structure can directly loosen the fastener 11 (screw) of the pump body, the pump cover and the middle-open type filler box, withdraw from the middle-open type filler box, open the fastener 12 (screw) and the fastener 13 (screw), can detach all fillers, does not need to detach the pump body and the pump cover, and is very convenient, time-saving and labor-saving.
