Abstract
The invention provides a conveniently-dismounted upright single-stage double-suction centrifugal pump, which is high in hydraulic performance, stable in operation, convenient to install, overhaul and maintain, and is provided with a rotor part assembly and a pump body part which are convenient to mount and dismount. The conveniently-dismounted upright single-stage double-suction centrifugal pump is of a radially split structure in which two ends of a pump shaft support the pump body, is vertically mounted, and structurally comprises the pump body, a pump cover, an impeller, a bearing body, a motor bracket, a water-guide bearing body and a driving motor. The conveniently-dismounted upright single-stage double-suction centrifugal pump is simple and compact in structure; the rotor part of the single-stage double-suction centrifugal pump can be integrally taken out just by loosing bolts for connecting and fixing the pump body and the pump cover when the pump is dismounted for overhauling, therefore, the pump is very convenient and simple to dismount for overhauling; and the conveniently-dismounted upright single-stage double-suction centrifugal pump occupies a small area so that a lot of capital construction investments can be saved for enterprises.
Description
Technical field
The present invention relates to a kind of pump, particularly relate to a kind of rotor part assembly and 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
The purpose of this invention is to provide a kind of hydraulic performance height, 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 prior art dismounting, the big problem of installation floor space.
Technological scheme of the present invention is as follows:
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.
Advantageous effect of the present invention is as follows:
1, rotor part assembly and pump housing parts are for ease of disassembly and assembly structure, its simple and compact equipment structure when the maintenance dismounting, only need be unclamped the bolt that is connected and fixed the pump housing and pump cover, can extract out the rotor part of single-stage double-suction centrifugal pump is whole, make very easy that the maintenance disassembly process of pump becomes.
2, the compact equipment floor space is little, can save a large sum of capital investment for using enterprise.
