Abstract
The utility model relates to a kind of lower bearing structure of vertical stage pump, this lower bearing structure comprises bearing support (1), sliding bearing (2), axle sleeve (5) and gland (3), described bearing support (1) is arranged on the bottom of the pump housing (6), the top of bearing support (1) is provided with gland (3), described sliding bearing (2) is arranged in the inner chamber of bearing support (1), described axle sleeve (5) is set on pump shaft (7), and is arranged in sliding bearing (2) through gland (3) with pump shaft (7).Compared with prior art, the utility model structure is simple, and the part cooperatively interacted is less, can effectively eliminate because part coordinates many and problem that is that cause axle sleeve and sliding bearing concentricity bad, the effectively working life of prolongation sliding bearing.
Description
Technical field
The utility model belongs to Multi-stage pump structure design field, relates to a kind of lower bearing structure of vertical stage pump.
Background technique
At present, the lower bearing structure of existing MODEL VERTICAL MULTISTAGE PUMP is more complicated, and part is more, is provided with bearing support in the lower end of inlet segment, and load sliding bearing in bearing support, axle sleeve rotates in sliding bearing.The requirement on machining accuracy of each part is high, and slightly machining accuracy does not reach requirement, the concentricity of axle sleeve and sliding bearing just may be caused bad, and cause sliding bearing heavy wear, affect the normal work of MODEL VERTICAL MULTISTAGE PUMP.
Summary of the invention
The purpose of this utility model is exactly the lower bearing structure in order to overcome defect that above-mentioned prior art exists and the vertical stage pump that provides a kind of number of spare parts that cooperatively interacts less.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of lower bearing structure of vertical stage pump, this lower bearing structure comprises bearing support, sliding bearing, axle sleeve and gland, described bearing support is arranged on the bottom of the pump housing, the top of bearing support is provided with gland, described sliding bearing is arranged in the inner chamber of bearing support, described axle sleeve is set on pump shaft, and is arranged in sliding bearing through gland with pump shaft.
The center of described gland is provided with axis hole, and the axis hole that the pump shaft with axle sleeve passes gland center is arranged in sliding bearing.
Described gland is arranged on the top of bearing support by fixing bolt.Gland can compress by fixing bolt, and gland can apply impacting force to sliding bearing, thus is firmly fixed in the inner chamber of bearing support by sliding bearing, ensures that axle sleeve and sliding bearing have good concentricity all the time.
Described bearing support is arranged on the bottom of the pump housing by casting.
MODEL VERTICAL MULTISTAGE PUMP operationally, axle sleeve rotates in sliding bearing, because gland can compress by fixing bolt, gland applies impacting force to the sliding bearing in bearing support inner chamber, this just makes can not produce relative sliding between sliding bearing and axle sleeve, thus ensures that axle sleeve and sliding bearing are in the long-term work of pump, remain good concentricity, this just can eliminate because of sliding bearing and axle sleeve concentricity bad and the problem of heavy wear occurs, the normal operation of MODEL VERTICAL MULTISTAGE PUMP can be ensured.
Compared with prior art, the utility model structure is simple, and the part cooperatively interacted is less, can effectively eliminate because part coordinates many and axle sleeve that is that cause is bad with sliding bearing concentricity problem, the effectively working life of prolongation sliding bearing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the lower bearing structure of a kind of vertical stage pump of the utility model;
Description of symbols in figure:
1-bearing support, 2-sliding bearing, 3-gland, 4-fixing bolt, 5-axle sleeve, the 6-pump housing, 7-pump shaft.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment:
As shown in Figure 1, a kind of lower bearing structure of vertical stage pump, this lower bearing structure comprises bearing support 1, sliding bearing 2, axle sleeve 5 and gland 3, bearing support 1 is arranged on the bottom of the pump housing 6 by casting, the top of bearing support 1 is provided with gland 3, sliding bearing 2 is arranged in the inner chamber of bearing support 1, and axle sleeve 5 is set on pump shaft 7, and is arranged in sliding bearing 2 through gland 3 with pump shaft 7.
The center of gland 3 is provided with axis hole, and the axis hole that the pump shaft 7 with axle sleeve 5 passes gland 3 center is arranged in sliding bearing 2.Gland 3 is fixed on the top of bearing support 1 by fixing bolt 4.Gland 3 can compress by fixing bolt 4, and gland 3 can apply impacting force to sliding bearing 2, thus is firmly fixed on by sliding bearing 2 in the inner chamber of bearing support 1, ensures that axle sleeve 5 and sliding bearing 2 have good concentricity all the time.
MODEL VERTICAL MULTISTAGE PUMP operationally, axle sleeve 5 rotates in sliding bearing 2, because gland can be pressed 3 tight by fixing bolt 4, sliding bearing 2 in gland 3 pairs of bearing support 1 inner chambers applies impacting force, this just makes can not produce relative sliding between sliding bearing 2 and axle sleeve 5, thus ensure that axle sleeve 5 and sliding bearing 2 are in the long-term work of pump, remain good concentricity, this just can eliminate the problem that heavy wear occurs because sliding bearing 2 and axle sleeve 5 concentricity are bad, can ensure the normal operation of MODEL VERTICAL MULTISTAGE PUMP.
