Abstract

The utility model provides a conveniently-detachable vertical type single-stage double-suction centrifugal pump which has the advantages of high hydraulic performance, stability in operating and convenience for mounting, overhauling and maintaining, wherein the rotor component assembly and the pump body component of the centrifugal pump are conveniently detachable/mountable; two ends of a pump shaft are adopted to support the radial subdivision structure of a pump body; the mounting manner of the centrifugal pump is a vertical type. The centrifugal pump comprises the pump body, a pump cover, an impeller, a bearing body, a motor bracket, a water-guiding bearing body and a driving motor. The conveniently-detachable vertical type single-stage double-suction centrifugal pump provided by the utility model has the advantages that: the centrifugal pump has a simple and compact structure; when the pump is detached for overhauling, the rotor component of the single-stage double-suction centrifugal pump can be drawn out by only unscrewing screw bolts which are used for fixedly connecting the pump body with the pump cover, so that the process for detaching the pump for overhauling becomes very simple and convenient; and the centrifugal pump has a small floor space, thus a lot of money for the investment in capital construction can be saved for enterprises using the conveniently-detachable vertical type single-stage double-suction centrifugal pump.

Description

Easy-to-dismount type vertical single stage double-suction centrifugal pump
Technical field
The utility model relates to a kind of pump, particularly relates to a kind of rotor part assembly and the pump housing parts easy-to-dismount type vertical single stage double-suction centrifugal pump for ease of dismounting.
Background technique
The single-stage double-suction centrifugal pump is a kind of centrifugal pump of large-scale big flow, is widely used in factory, mine, urban water supply and sewerage, also can be used for power station, large hydraulic engineering, farmland discharging-irrigating etc.
The single-stage double-suction centrifugal pump of present domestic extensive use; Be in the level and open, axial subdivision, the side suction pump that pump bottom pin supports; Because of this kind pump suction pipe is positioned at a side of the pump housing, so and its longitudinal center line and the perpendicular this pump of vertical center line be called side suction pump.The single-stage double-suction centrifugal pump is the horizontal installation of ground level, so its installation floor space is also just relatively large.
Summary of the invention
It is high that the purpose of the utility model provides a kind of hydraulic performance; Stable; Be convenient to install the rotor part assembly and the easy-to-dismount type vertical single stage double-suction centrifugal pump of pump housing parts for ease of dismounting of maintenance maintenance, it is loaded down with trivial details to have solved in the existing technology dismounting, the big problem of installation floor space.
The technological scheme of the utility model is following:
The water pilot bearing body is installed on the pump housing; Inboard seam of pump cover and pump housing seam are tightly connected, and pump cover outside seam is connected with bearing support lower end seam, and bearing support upper end seam is connected with electric machine support lower end seam, and electric machine support upper end seam is connected with the output terminal seam of drive motor; The shaft seal cavity that the pump shaft of bearing support passes the pump cover center is connected with impeller, and the pump shaft lower end is equipped with the water pilot bearing cover, and insert in the water pilot bearing body pump shaft bottom, and the pump coupling is installed in the pump shaft upper end.
The described pump housing is provided with volute casing and the pump housing sucks the letter body, and the water intake of the pump housing and water outlet are positioned at the both sides of the pump housing, and the center seam of pump lower end is installed the water pilot bearing body.
The shaft seal cavity of described pump cover and pump housing top and pump cover suck letter body cast solid.
Bearing letter body is set in the described bearing support, bearing and pump shaft are installed in the bearing letter body.
The output axle head of described drive motor is installed motor coupler.
The utility model has the advantages of as follows:
1, rotor part assembly and pump housing parts are for ease of disassembly and assembly structure; Its simple and compact equipment structure in maintenance during dismounting, only need be unclamped and connects the fixedly bolt of the pump housing and pump cover; Can extract out the rotor part of single-stage double-suction centrifugal pump is whole, the ten minutes that the maintenance disassembly process of pump is become is easy.
2, the compact equipment floor space is little, can save a large sum of capital investment for using enterprise.
