Abstract
The utility model discloses an integral assembly shaft seal device for a suspension pump, which comprises a shaft sleeve, a mechanical seal gland, a mechanical seal moving ring, a mechanical seal fixed ring and a mechanical seal bushing. The mechanical seal bushing is sleeved at one end of the shaft sleeve and is align to the end of the shaft sleeve. The outer diameter of one section, which is close to the outer side, of the mechanical seal bushing is smaller than that of the other section of the mechanical seal bushing, and accordingly a shoulder is formed. The mechanical seal moving ring adjacent to the mechanical seal bushing is sleeved on the outside of the shaft sleeve. Holes are arranged on the circumference of the mechanical seal gland close to the outer end and correspond to screw holes on a pump cover of the suspension pump, a hole is arranged in the center of the mechanism seal gland, and a pump shaft penetrates through the hole. A groove is arranged in the mechanism seal gland and adjacent to the hole of the mechanical seal gland, and the mechanical seal fixed ring is placed in the groove. During assembly, the mechanical seal fixed ring adjacent to the mechanical seal moving ring is sleeved on the shaft sleeve, and the shaft sleeve, the mechanical seal bushing, the mechanical seal moving ring and the mechanical seal fixed ring are arranged in a sealing cavity of the pump cover of the suspension pump. The mechanical seal compression amount can be effectively controlled, and the shaft seal device can be assembled integrally and is assembled conveniently. When mechanical seals need to be changed or maintained, the shaft seal device can be taken down integrally to be dismounted and maintained, and accordingly a water pump is maintained conveniently.
Description
Technical field
The utility model relates to the gland seal device technical field, particularly relates to the whole assembling of a kind of suspension-type pump gland seal device.
Background technique
Existing pump shaft seal apparatus does not generally have axle sleeve, and fed sheet of a media directly touches with being coupling, and non-integral type, and erection sequence is installed according to the part order, the neglected loading and the envelope inconvenience of more changing planes easily, and gland seal device can not independently wholely assemble and disassemble.
The model utility content
The utility model technical problem to be solved is the whole assembling of a kind of suspension-type pump gland seal device that proposes to existing technical problem in the above-mentioned existing technology, but the gland seal device integrated type install with integrated type and disassemble maintenance, be convenient to maintenance.
The technical problem that the utility model requires to solve can realize through following technological scheme:
The whole assembling of suspension-type pump gland seal device is characterized in that, comprises axle sleeve, machine sealed cover, mechanical sealing linkage ring, mechanical sealing static ring, machine envelope lining; Said machine envelope lining is enclosed within axle sleeve one end, and aligns with this sleeve end, and machine envelope lining one section external diameter in the outer part is less than its another section external diameter; Form shoulder, said mechanical sealing linkage ring next-door neighbour machine envelope lining is enclosed within the axle sleeve outside, and said machine sealed cover upwards has the hole near the week of outer end; Said hole is corresponding with screw on the suspension-type pump pump cover; Said machine sealed cover center portion is useful on the hole that pump shaft passes through, and is inner at the machine sealed cover, and the position in next-door neighbour hole is fluted; Said mechanical sealing static ring is placed in the said groove; During assembling, said mechanical sealing static ring next-door neighbour mechanical sealing linkage ring is enclosed within on the axle sleeve, and said axle sleeve, machine envelope lining, mechanical sealing linkage ring and mechanical sealing static ring place in the sealed chamber of suspension-type pump pump cover.
Said machine sealed cover is fixed on the pump cover of suspension-type pump through stud bolt.
Owing to adopted technique scheme, the utility model can effectively be controlled mechanical seal compression when producing assembling, also can carry out the integrated type assembling to gland seal device simultaneously, is convenient to assembling; When mechanical seal need be changed or safeguard, can integral body take off the gland seal device part, disassemble maintenance, be convenient to the maintenance of water pump.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the utility model comprises axle sleeve 1, machine sealed cover 2, mechanical sealing linkage ring 3 and mechanical sealing static ring 4, machine envelope lining 5.
Like Fig. 2, shown in Figure 3, when assembling, at first axle sleeve 1 and machine are sealed lining 5 by putting down and fixedly assembling, then mechanical sealing linkage ring 3 is enclosed within on the axle sleeve 1; In advance mechanical sealing static ring 4 is packed in the machine sealed cover 5; The axle sleeve 1 and the Assembly of machine envelope lining 5 are packed in the sealed chamber 7 of pump cover 6, block mutually with pump cover 6 with the shoulder of machine envelope lining 5, the Assembly of mechanical sealing static ring 4 and machine sealed cover 2 of packing into, and tighten stud 8.Integrated shaft seal apparatus structure assembled.
Integrated shaft seal apparatus parts are pressed in the suspension 9 by direction shown in Figure 2, and the rear-wheel hub through impeller 10 compresses axle sleeve 1, makes shoulder and the pump cover of machine envelope lining 5 open in 6 minutes, and makes mechanical seal effectively produce decrement, the formation closed chamber.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
