Abstract
The invention discloses an axial adjustment structure for a rotor of a single-stage cantilever-type centrifugal pump. The axial adjustment structure for the rotor of the single-stage cantilever-type centrifugal pump comprises a pump body (1), a front wear-resistant plate (3), an open-type impeller (4), a rear wear-resistant plate (5), a pump cover (6), a bearing part (7), a bearing body (8) and a bearing cover (10), wherein the front wear-resistant plate (3) is installed on the pump body (1), the rear wear-resistant plate (5) is installed between the pump body (1) and the pump cover (6), the open-type impeller (4) and the bearing part (7) are assembled together to form a rotor part, the bearing body (8) is installed on the central spindle of the bearing part (7) and the bearing cover (10) is fastened on the bearing part (7). The axial adjustment structure for the rotor of the single-stage cantilever-type centrifugal pump has the advantages that the open-type impeller does not interfere with the front wear-resistant plate and the rear wear-resistant plate during assembling and the pump unit can run normally.
Description
Technical field
The present invention relates to a kind of single-stage cantilever formula centrifugal pump rotor axial adjusting structure.
Background technique
In the prior art, PC O pump is single-stage cantilever formula centrifugal pump, structurally impeller is open type, separate with front and rear cover plate, be applicable to the larger medium of graininess, design for preventing the filter medium clogging runner, because unshrouded impeller separates with front and rear cover plate, the interference phenomenon of impeller and front and rear cover plate occurs in assembly process easily, causes the pump group normally to move.
Summary of the invention
The purpose of this invention is to provide a kind of single-stage cantilever formula centrifugal pump rotor axial adjusting structure.
The technological scheme that the present invention adopts for achieving the above object is: a kind of single-stage cantilever formula centrifugal pump rotor axial adjusting structure, comprise the pump housing (1), front wearing plate (3), unshrouded impeller (4), rear wearing plate (5), pump cover (6), bearing part (7), bearing support (8) and bearing gland (10), described front wearing plate (3) is installed on the pump housing (1), described rear wearing plate (5) is installed between the pump housing (1) and the pump cover (6), described unshrouded impeller (4) assemblies rotor part with bearing part (7), described bearing support (8) is installed on the axle core of bearing part (7), and described bearing gland (10) is fastened on the bearing part (7).
The described pump housing (1) is connected fastening with front wearing plate (3) by the first bolt (2).
Described bearing gland (10) is fastened on the bearing part (7) by the second bolt (9).
Described bearing gland (10) is provided with tight a bolt (11).
A kind of single-stage cantilever formula of the present invention centrifugal pump rotor axial adjusting structure can not interfere phenomenon with forward and backward wearing plate at assembly process middle open type impeller, and the pump group can normally be moved.
Description of drawings
Fig. 1 is the structural representation of a kind of single-stage cantilever formula of the present invention centrifugal pump rotor axial adjusting structure.
Among the figure: 1, the pump housing; 2, the first bolt; 3, front wearing plate; 4, unshrouded impeller; 5, rear wearing plate; 6, pump cover; 7, bearing part; 8, bearing support; 9, the second bolt; 10, bearing gland.
Embodiment
As shown in Figure 1, single-stage cantilever formula centrifugal pump rotor axial adjusting structure, comprise the pump housing 1, front wearing plate 3, unshrouded impeller 4, rear wearing plate 5, pump cover 6, bearing part 7, bearing support 8 and bearing gland 10, front wearing plate 3 is installed on the pump housing 1, connect fastening with the first bolt 2, rear wearing plate 5 is installed between the pump housing 1 and the pump cover 6, utilize assembly relation fastening, bearing part 7 and the rear rotor part that forms of unshrouded impeller 4 assemblings, axle core components by bearing support 8 whole bearing part can axially adjusted, before the pump group leans against the unshrouded impeller 4 of whole rotor part front end first in assembly process on the wearing plate 3, assemble complete after, the 11 continuous degree of depth that are screwed into bearing gland 10 that increase come the adjusting axle core components in axial position by tighting a bolt, in being screwed into 11 the process of tighting a bolt, to constantly carry out jiggering, in the jiggering process, when no longer including interference phenomenon in the pump group, stop to be screwed into and tight a bolt 11, with the second bolt 9 bearing gland 10 is fastened on the bearing part 7, so far pump assembling is joined complete, unshrouded impeller can be with not front, rear wearing plate interferes, and the pump group can normally be transported.
