Description
Technical field
The present invention relates to a kind of horizontal multi-stage centrifugal pump, belong to field of mechanical technique.
Background technology
Centrifugal pump is to be rotated using impeller and make water that centrifugal motion occur come work.Water pump is before activation, it is necessary to makes in pump case and suction hose full of water, then starts motor, pump shaft impeller and water is done high speed rotary motion, and water occurs centrifugal motion, is thrown toward impeller outer edge, and the pressure pipe road of water pump is flowed into through the runner of volute pump case.Centrifugal pump can be divided into centrifugal pump of single stage type and centrifugal multistage pump multiple centrifugal pump by the number of impeller number on pump shaft.Centrifugal pump of single stage type is used for delivery temperature no more than 80 clear water shooted a retrievable arrow and the liquid of the similar water of physicochemical properties, it is adaptable to industry and city water, draining and field irrigation.
Existing centrifugal pump has following weak point：1）Flow is small, influences transfer efficiency；2）After axle is using a period of time, it is easily damaged.
The content of the invention
The purpose of the present invention is customer service the deficiencies in the prior art part, there is provided a kind of horizontal multi-stage centrifugal pump.
Horizontal multi-stage centrifugal pump of the invention, including yielding coupling（1）With yielding coupling（1）Connected rotor（3）With rotor（3）Coaxial rolling bearing（4）With rolling bearing（4）The connected pump housing, the described pump housing includes suction casing（13）With suction casing（13）Connected stator（15）With stator（15）Connected multiple stage casings（17）With stage casing（17）Connected final stage stator（21）With final stage stator（21）Connected Spit Section（22）, water sealing (sealing water) pipe（33）And balanced water returning pipe（39）, described suction casing（13）And stator（15）Between be provided with sealing ring（14）.
Horizontal multi-stage centrifugal pump of the invention, has the following technical effect that：Axle and motor coaxle, stablize, long service life, reducing energy consumption.
