Abstract
The utility model provides a horizontal multi -stage centrifugal pump, including resilient coupling (1), rotor (3) that link to each other with resilient coupling (1), antifriction bearing (4), with antifriction bearing (4) the continuous pump body coaxial with rotor (3), the pump body include suction casing (13), stator (15) that link to each other with suction casing (13), a plurality of middle sections (17) that link to each other with stator (15), final stage stator (21) that link to each other with middle section (17), discharge casing (22) that link to each other with final stage stator (21), water seal pipe (33) and balance wet return (39). The utility model discloses a horizontal multi -stage centrifugal pump has following technological effect: the axle is coaxial with the motor, stabilizes, and long service life reduces the energy consumption.
Description
Technical field
The utility model relates to a kind of horizontal multi-stage impeller pump, belongs to field of mechanical technique.
Background technology
Impeller pump utilizes impeller to rotate and make water generation centrifugal motion carry out work. Water pump is before activation, it is necessary to making to be full of in pump case and water absorption tube water, then start motor, make pump shaft impeller and water do high speed rotary motion, water generation centrifugal motion, is thrown toward impeller outer edge, and the runner through snail shape pump case flows into the setting-out pipeline of water pump. Impeller pump can be divided into single-stage centrifugal pump and stage chamber pump by the number of impeller number on pump shaft. Single-stage centrifugal pump is used for the liquid that delivery temperature is no more than 80 clear water shooted a retrievable arrow and physicochemical property similar water, is applicable to industry and city water, draining and field irrigation.
Existing impeller pump has following weak point: 1) flow is little, affects transport efficiency; 2) after axle uses for some time, it is easy to damage.
Summary of the invention
The purpose of this utility model is customer service the deficiencies in the prior art part, it is provided that a kind of horizontal multi-stage impeller pump.
Horizontal multi-stage impeller pump of the present utility model, comprise resilient coupling (1), the rotor (3) being connected with resilient coupling (1), the rolling bearing (4) coaxial with rotor (3), with the pump housing that rolling bearing (4) is connected, the described pump housing comprises suction section (13), with the stator (15) that suction section (13) is connected, the multiple stage casings (17) being connected with stator (15), the final stage stator (21) being connected with stage casing (17), the Spit Section (22) being connected with final stage stator (21), syphon trap (33) and balanced water returning pipe (39), it is provided with wear ring (14) between described suction section (13) and stator (15).
Horizontal multi-stage impeller pump of the present utility model, has following technique effect: axle and motor coaxle, stablizes, it may also be useful to the life-span is long, reduces energy consumption.
