On water guide vane 3, it is located at influent side, reduces the negative effect to pump efficiency, while motor drive shaft and 3 rigidity of water inlet guide vane are straight
Even, transmission parts usage amount, the common size for reducing the pump housing of two aspects are reduced.
In another embodiment provided by the invention, it is preferred that the impeller 7 includes connecting pole and is set to the connection
Multiple blades on column, connecting pole are socketed on one end of transmission shaft 9, transmit torque by key, while connecting pole passes through clamp screw
Nail 6 is fixed on transmission shaft 9, and the rotation direction of the thread rotary orientation of holding screw 6 and the transmission shaft 9 is on the contrary, can so keep away
Screwless loosens during pump operation.
Further include the envelope for being set to 3 inside of water inlet guide vane further in further embodiment provided by the invention
Closed shell 13, closing shell 13 are water-tight structure, and closing shell 13 surrounds a sealing accommodating chamber, the hydraulic pressure with the water inlet guide vane 3
One end that motor drive shaft is provided on motor 11 is located in the sealing accommodating chamber, and so effect is to be set on hydraulic motor 11
The one end for setting motor drive shaft provides a sealed environment for preventing liquid from entering, and prevents liquid from polluting hydraulic structure, or to motor
The rotation of axis forms negative effect.
In order to ensure to seal the sealing performance of accommodating chamber, closing shell 13 and the corresponding part intake on guide vane 3 can be arranged
For water-tight structure, hydraulic motor 11 and junction setting one static sealing structure such as O-ring seals 10 of water inlet guide vane 3 are
Can, and the junction of transmission shaft 9 and closing shell 13 then needs that dynamic sealing mechanism is arranged, submersible axial flow pump is dynamic close in the prior art
Envelope is all made of mechanical seal, and sealing is preferable, but the size occupied is larger, further, as shown in Fig. 2, the present embodiment is adopted
Realize that the sealing at this, transmission shaft 9 are connected to by the first seal assembly 8 on the closing shell 13 with the first seal assembly 8, the
One seal assembly 8 includes sealing block, and the both ends of sealing block are bonded with closing shell 13 and transmission shaft 9 respectively, wherein the one of sealing block
End is sealedly attached to by O-ring 103 on the closing shell 13, and the other end of sealing block passes through the car seal circle that is set up in parallel
102 and vehicle type dustband 104 and 9 dynamic sealing of the transmission shaft；The case hardness of the transmission shaft 9 is configured as being not less than
50HRC such as makes case hardness be more than 55HRC by chromium plating (thickness 0.1mm), i.e., dust-proof by car seal circle 102 and vehicle type
Circle 104 realizes dynamic sealing, in order to ensure sealing effect and cope with the hydraulic motor 11 of different model, 102 He of car seal circle
Vehicle type dustband 104 can be provided with multigroup, the advantage is that, on the one hand reduce size by car seal, on the other hand,
