Abstract
The utility model discloses a slurry pump combination oil seal structure, comprising a bearing, a rotating shaft, a bearing gland, a labyrinth gland and a framework oil seal, wherein felt rings are also arranged on the back of the framework oil seal and between the bearing gland and the labyrinth gland, and a labyrinth seal is also arranged between the bearing gland and the rotating shaft; and since the felt ring seal and the labyrinth seal are additionally arranged, the utility model is distinct in gradation, prevents lubrication oil from leaking, also prevents outside impurities from entering a lubrication oil tank, and ensures the lubrication effect.
Description
Technical field
The utility model relates to a kind of sealing configuration, particularly a kind of sealing configuration of slag stock pump.
Background technique
At present,, reveal from lubricating oil bath by running shaft, usually between bearing and labyrinth lid, only be provided with outside framework oil seal, as shown in Figure 1 in order to prevent lubricant oil for the slag stock pump.But this sealing configuration only is one deck sealing, still has oil leakage behind the outside framework oil seal, and simultaneously, introduced contaminants also may enter lubricating oil bath in the running shaft rotary course, thereby pollution lubricating oil influences lubrication effect.
The model utility content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of combined type slag stock pump oil seal structure.
The technical solution adopted in the utility model is such: a kind of slag stock pump combination oil seal structure, comprise bearing, running shaft, bearing gland, labyrinth lid and outside framework oil seal, after described outside framework oil seal, between the lid of bearing gland and labyrinth, also be provided with the felt circle, can collect the lubricant oil of reinforced seal back small amount of leakage, and make lubricant oil be back to oil sump by 45 ° of back flashes on the bearing gland.
As preferably: between described bearing gland and running shaft, also be provided with labyrinth seal.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: owing to set up sealing of felt circle and labyrinth seal, well arranged, when preventing oil leakage, also avoid introduced contaminants to enter lubricating oil bath, guaranteed lubrication effect.
Description of drawings
Fig. 1 is the structural representation of the utility model background technique;
Fig. 2 is the utility model embodiment 1 a structural representation.
Mark among the figure: 1 is running shaft, and 2 is oil sump, and 3 is bearing, and 4 is outside framework oil seal, and 5 are the labyrinth lid, and 6 is the felt circle, and 7 are labyrinth seal, and 8 is bearing gland.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 2, a kind of slag stock pump combination oil seal structure, comprise bearing 3, running shaft 1, bearing gland 8, labyrinth lid 5 and outside framework oil seal 4 are after described outside framework oil seal 4, bearing gland 8 also is provided with felt circle 6 between covering 5 with the labyrinth, can collect the lubricant oil of reinforced seal 4 back small amount of leakage, and make lubricant oil be back to oil sump 2 by 45 ° of back flashes on the bearing gland 8, between described bearing gland 8 and running shaft 1, also be provided with labyrinth seal 7.
Since set up 6 sealing and the labyrinth seals 7 of felt circle, well arranged, when preventing oil leakage, also avoided introduced contaminants to enter lubricating oil bath 2, guaranteed lubrication effect.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
