Abstract

The utility model discloses an integral component for a lower bearing gland and a connecting pipe of a vertical submersible slurry pump, which belongs to the field of slurry pumps. The lower bearing gland and the connecting pipe are integrally molded; since the lower bearing gland and the connecting pipe are integrally molded, that is, the lower bearing gland and the connecting pipe are combined into a whole, the lower bearing gland is connected with the connecting pipe without a bolt; a bearing part is connected with the connecting pipe only through six bolts, however, twelve bolts are required for connection in the prototype structure, and the number of the bolts is reduced by a half than before; therefore, the external dimension of the connecting pipe is greatly reduced, the physical dimension of appearance of the bearing bracket part is correspondingly reduced, and the weight of the bearing bracket part is reduced by more than 30 percent under the conditions of the same bearing diameter and the same bearing spacing.

Description

Vertical slag slurry pump under liquid bearing gland and adapter integral component

Technical field

The utility model relates to a kind of slag stock pump, particularly a kind of vertical slag slurry pump under liquid assembly.

Background technique

In present vertical slag slurry pump under liquid structure, dividing of lower bearing gland and adapter is arranged, so, when they are connected with the bearing housing parts, need six bolts to connect respectively, be that the lower bearing gland needs six bolts to be connected with the bearing housing parts, taking over also needs six bolts to be connected with the bearing housing parts, as described in Figure 1; The bolt quantity that this Placement is used is more, corresponding, because six attachment bolts of lower bearing gland and bearing housing parts need enough spanner activity spaces, thereby the profile that causes taking over strengthens, bearing bracket part profile is also corresponding bigger, whole pump weight increases, and product cost is higher.

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 bearing gland to take over integral component.

The technical solution adopted in the utility model is such: a kind of vertical slag slurry pump under liquid bearing gland is taken over integral component, and lower bearing gland and adapter are one-body molded.

In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: because lower bearing gland and adapter are one-body molded, promptly be integrated, thereby make the lower bearing gland with take between no longer need bolt to be connected, only needing six bolts to be connected between bearing part and the novel adapter gets final product, and prototype structure needs 12 bolts to connect, connecting bolt quantity is reduced to original half, taking over boundary dimension greatly reduces, bearing bracket part profile entity size reduces accordingly, and under the situation of identical bearing diameter and distance between bearings, the weight saving of bearing bracket part is more than 30%.

Description of drawings

Fig. 1 is the structural representation of the utility model background technique;

Fig. 2 is a structural representation of the present utility model.

Mark among the figure: 1 for taking over, and 2 is the lower bearing gland, and 3 is bolt, and 4 are lower bearing gland adapter combination.

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 vertical slag slurry pump under liquid lower bearing gland and adapter integral component, lower bearing gland 2 and adapter 1 are one-body molded, take over combination 4 thereby form the lower bearing gland.

Because lower bearing gland 2 and adapter 1 are one-body molded, promptly be integrated, thereby make lower bearing gland 2 with take over 1 between no longer need bolt 3 to be connected, bearing part with take between only need six bolts 3 to be connected to get final product, connecting bolt 3 quantity are reduced to original half, take over 1 boundary dimension and greatly reduce, and bearing bracket part profile entity size reduces accordingly, under the situation of identical bearing diameter and distance between bearings, the weight saving of bearing bracket part is more than 30%.When alleviating slag stock pump weight, reduced cost of production.

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

A vertical slag slurry pump under liquid lower bearing gland with take over integral component, comprise lower bearing gland and adapter, it is characterized in that: lower bearing gland and take over one-body molded.
