Abstract
The utility model discloses an axially-split single-stage double-suction centrifugal pump which comprises a pump body, a pump cover, an impeller, a shaft, a sealing ring and a shaft sleeve, and is characterized in that the two sides under the axis line of the pump body along the horizontal direction vertical to the axis are respectively provided with a suction inlet and a discharge hole; the shaft passes through the pump body and is respectively provided with a bearing body at the two sides of the pump body; and the impeller is positioned inside a cavity formed by the pump body and the pump cover. As the suction inlet and the discharge hole are arranged under the axis line of the pump body, overhauling can be finished without disassembling a water inlet pipe, a water outlet pipe and a motor; and furthermore, the centrifugal pump has the characteristics of stable performance, high efficiency, energy conservation, long service like, high universality and the like.
Description
Technical field
The utility model belongs to a kind of pump, specifically is a kind of axial subdivision single-stage double-suction centrifugal pump.
Background technique
The single-stage double-suction centrifugal pump is applied to industries such as chemical industry, chemical fertilizer, metallurgy, papermaking, sugaring, pharmacy, coal washing, sewage treatment mostly, as carrying the Korrosionsmedium instrument that cleans or have micro-solid particle.At present, the single-stage double-suction centrifugal pump in the production application mostly be under go out structure, must disassemble importing and exporting water pipe and motor during maintenance, so not only complicated overhaul procedure has improved the maintenance difficulty, makes part be easy to wearing and tearing simultaneously, reduce working life, increased the cost expenditure.
The model utility content
The purpose of this utility model provides a kind of axial subdivision single-stage double-suction centrifugal pump, can finish maintenance need not dismantling under the situation of importing and exporting water pipe and motor, has characteristics such as stable performance, energy-efficient, long service life, versatility height.
The technical solution of the utility model is as follows:
Axial subdivision single-stage double-suction centrifugal pump, include the pump housing, pump cover, impeller, axle, seal ring, axle sleeve, it is characterized in that described pump housing shaft axis below, suction port and discharge opening are arranged both sides respectively in horizontal direction with axis normal, axle passes the pump housing, being positioned at pump housing both sides on the axle has bearing support respectively, and impeller is positioned at the cavity of the pump housing and pump cover formation.
Described impeller is the design of double suction enclosed runner, is furnished with removable wear ring.
Described bearing support is respectively that nonpowered axle holds and driving bearing, and nonpowered axle holds the employing angular contact ball bearing, and driving bearing adopts short cylindrical rolling roller bearing.
Described bearing support contains anti-drive end and drive end, and anti-drive end adopts angular contact ball bearing, and drive end adopts short cylindrical rolling roller bearing.
It is scroll casing type axial subdivision structure that the utility model adopts.Pump intake and discharge opening below the water pump shaft axis, with axis normal in horizontal direction, need not dismounting during maintenance and import and export water pipe and motor.The design of double-entry impeller enclosed runner is furnished with removable wear ring, efficient height, stable.Anti-drive end adopts angular contact ball bearing, and drive end adopts short cylindrical rolling roller bearing, but balance residual axial force and radial force.Bearing adopts thin oil lubricant, high lubricating effect.Strengthen axle setting, the rotor good rigidly, supporting is stable.Simultaneously can adopt multiple seal style, as soft packing seal or mechanical seal.Make integral product have outstanding features such as stable performance, energy-efficient, long service life, versatility height.
