Description
Technical field：
It is easy to fixed axial-flow pump the present invention relates to a kind of, belongs to mechanical equipment technical field.
Background technology：
Axial-flow pump impeller is equipped with 2~7 blades, in tubular pump case internal rotation.Fixed guide vane is housed on the pump case of upper impeller,
To eliminate the rotary motion of liquid, it is allowed to be changed into being axially moved, and the kinetic energy of rotary motion is changed into pressure energy.Axial-flow pump
Stage type is made in typically single stage type, minority.Range of flow is very big, be 180~360 ten thousand steres/when；Lift is typically at 20 meters
Below.Axial-flow pump is generally vertical, and impeller is immersed under water, also there is horizontal or inclined axial flow.The impeller of small axial flow pump
, it is necessary to be started with vacuum pump discharges diversion when installation site is higher by the water surface.The blade of axial-flow pump is divided to fixed and adjustable two kinds
Structure.The applying working condition of Large Axial Flow Pump often needs to make larger variation in operation, adjusts the established angle of blade and pump can be made to exist
High efficient area operation is maintained under different operating modes.The blade angle of pony pump is usually fixed.Axial-flow pump is primarily adapted for use in
The occasion of low lift, big flow, such as irrigation, water drainage, dock draining, the water level regulation of canal ship lock, or follow as power plant is large-scale
Ring water pump.The higher axial-flow pump of lift（Twin-stage is made if necessary）It is available for the hydraulic jet propulsion of shallow draft ship to be used.
During the installation of existing vertical-type axial-flow pump sometimes because foundation beam set must haggle over it is small, ground placement of foot away from base side distance compared with
It is small, preformed hole mode such as is used, the intensity of foundation beam will be influenceed；And directly foundation bolt and concrete are once poured and are filled in one
Rise, foundation bolt is difficult to be accurately positioned.
The content of the invention：
The purpose of the present invention be for above-mentioned problem provide it is a kind of be easy to fixed axial-flow pump, it is simple in construction to be easy to pacify
Dress, and axial-flow pump is more stable after installation, and loosening, reliable and stable work will not be caused because of vibration.
Above-mentioned purpose is realized by following technical scheme：
It is easy to fixed axial-flow pump, including the first pump case and the second pump case for being connected with the first pump case, the second described pump case are set
Put and the top of the first described pump case, the first described pump case bottom are provided with water-inlet horn mouth, it is curved that top is provided with water outlet
Pipe, the second pump case the inside are provided with power set, and the power set connect drive shaft, and the drive shaft passes through described
First pump case simultaneously extends downwardly along the axial centre of the first pump case, and the bottom of the drive shaft is provided with stator and impeller, described
Ring-shaped clip is respectively arranged among first pump case and at described water-inlet horn mouth, each described ring-shaped clip passes through one group
Connecting rod connects upper support pin, and described upper support pin connects pre-buried pin by connector.
Described is easy to fixed axial-flow pump, and described power set use electro-motor.
Described is easy to fixed axial-flow pump, uses and is welded to connect between described connecting rod and described ring-shaped clip；Institute
