Description

Vertical sleeve mounting axial flow pump Technical Field The utility model relates to the technical field of axial flow pumps, in particular to a vertical sleeve-mounted axial flow pump. Background The submerged axial flow pump is mainly used for occasions with low lift and large flow, such as farm irrigation, urban water supply and drainage, power station water supply and drainage and the like. The use of axial flow pumps is installed in a variety of ways, such as coupled installation, wellbore installation, and the like. The advantage of coupling type installation is that it installs and overhauls conveniently, and the water pump directly hangs when the trouble maintenance, does not need to go into the aquatic, but its coupling structure occupation space is big, and construction cost is high. The shaft type installation has the advantages of low construction cost, but is complicated to install and detach. In the prior art, some vertical sleeve mounting axial flow pumps, such as a Chinese patent application number CN96232268.7, named vertical shaft axial flow pump, can directly hoist a shaft type pump component from a shaft by a crane, reduce the manual workload and achieve convenient installation and maintenance. However, the water outlet is opened laterally, the combination of the shaft and the pump body is not tight enough, the assembly and the disassembly are inconvenient, and the space required to be installed is large. Disclosure of utility model In order to overcome the defects of the prior art, the utility model aims to provide the vertical sleeve mounting axial flow pump which is convenient to mount and dismount, compact in structure, small in occupied space and good in filtering effect. The axial flow pump is characterized by comprising a vertical support, a shaft and an axial flow pump, wherein the vertical support is vertically arranged, the vertical support is fixed at the bottom end of the shaft, the axial flow pump is arranged in the shaft, the shaft comprises a middle cylinder, an upper cylinder, a middle cylinder flange and a cable seat, the upper cylinder is integrally formed at the top of the middle cylinder, the diameter of the upper cylinder is reduced from bottom to top, the middle cylinder flange is welded at the bottom end of the middle cylinder, the upper cylinder flange is welded at the top end of the upper cylinder, and a plurality of cable seats are fixed at the outer side of the upper cylinder. Further, the vertical support include support frame, bottom sprag ring and butt clamp flange between connect fixedly through a plurality of support frames, leave the gap between the adjacent support frame. Further, axial-flow pump include the pump body, the stator body, middle section shell and horn mouth, the stator body set up the outer end at the pump body, the middle section shell fix in the bottom of stator body, the horn mouth fix in the bottom of middle section shell, stator body outer lane clamp set up and fix in the middle section of thick bamboo flange and between the flange of butt clamp. Further, the cable seat is connected with a cable gland through a screw. Further, a filter cover is fixed at the bottom end of the horn mouth. Furthermore, a plurality of hanging rings are symmetrically welded on the outer side of the upper part of the middle cylinder. Further, two pump body hanging frames are symmetrically fixed on two sides of the top end of the pump body. Compared with the prior art, the vertical sleeve mounting axial flow pump has the beneficial effects that the axial flow pump is clamped and fixed between the middle cylinder flange and the opposite clamping flange through the outer ring of the guide vane body, and the vertical sleeve mounting axial flow pump is simple in connection mode and convenient to connect and detach among the vertical support, the shaft and the axial flow pump.
