In order to fix the first driving gear 3 on the driving shaft 21 and the first driven gear 31 on the rotating shaft 5, the base 1 is fixedly provided with the second supporting plate 4, the second supporting plate 4 is fixedly connected with the bearing 41, the inner ring of the bearing 41 is fixedly provided with the toothed ring 42, the toothed ring 42 is meshed and matched with the first driving gear 3, and the first driving gear 3 is meshed and connected with the first driven gear 31, so that the driving shaft 21 and the rotating shaft 5 are fixed.

The centrifugal pump body comprises a right pump body 7 and a left pump body 9 which are connected, a discharge port 71 is fixedly arranged at the top of the right pump body 7, and a suction port 91 is fixedly arranged on the left pump body 9. Wherein the right pump body 7 and the left pump body 9 are fixed by bolts

Impeller 8 sets up between the right pump body 7 and the left pump body 9, in order to make impeller 8 shift out from the centrifugal pump body, pivot 5 will outwards slide promptly, therefore, base 1 sliding fit slider 6, the first backup pad 62 of fixed connection on the slider 6, first backup pad 62 and pivot 5 fixed connection, first backup pad 62 is fixed to be set up adjusting nut 61, adjusting nut 61 screw-thread fit adjusting screw 63, adjusting screw 63 one end fixed connection hand wheel 64, adjusting hand wheel 64 makes adjusting screw 63 rotate, first backup pad 62 begins to slide, thereby pivot 5 begins to slide.

Further, the base 1 is fixedly connected with the centrifugal pump through a support frame 10, and a protection box 11 is arranged on the base 1. Wherein first driving gear 3, second driving gear 22, first driven gear 31 and second driven gear 51 all set up in guard box 11, and drive shaft 21 and pivot 5 all run through the lateral wall of guard box 11, and the articulated cooperation case lid 12 of guard box 11, case lid 12 and guard box 11 are fixed through the hasp 13 that sets up.

The working process of the present invention will be further described below:

when impeller 8 to this centrifugal pump clears up, can utilize the spanner to unscrew the bolt between the left pump body 9 and the right pump body 7, then unscrew the bolt between support frame 10 and base 1, thereby dismantle left pump body 9 from the right pump body 7, loosen hasp 13 after that, open case lid 12, then rotate hand wheel 64, make adjusting screw 63 can drive first backup pad 62 and pivot 5 side-to-side motion, drive first driven gear 31 simultaneously and slide left along first driving gear 3, thereby shift out the inner chamber of the right pump body 7 with impeller 8, can clear up impeller 8 and the inner chamber of the right pump body 7 after that.

After impeller 8 and the clearance of the right pump body 7 inner chamber finish, reverse rotation hand wheel 64 makes pivot 5 drive impeller 8 move right to accomodate impeller 8 to the inner chamber of the right pump body 7, utilize the wrench to install left pump body 9 and right pump body 7 each other after that, thereby accomplish the clearance of impeller 8 to this centrifugal pump. The problem that the cleaning process is complicated due to the fact that the shaft coupling of the output end of the rotating shaft 5 and the output end of the motor 2 needs to be disassembled in the cleaning process of the centrifugal pump impeller 8 at present is solved.

When the delivery capacity of the centrifugal pump body needs to be increased, the motor 2 is closed, then the rocker 16 is rocked, so that the screw 15 drives the sliding seat 23 and the motor 2 to slide rightwards, meanwhile, the second driving gear 22 is meshed with the second driven gear 51 to be connected, the first driving gear 3 is disengaged from the first driven gear 31 to be connected, then the motor 2 is started, so that the motor 2 drives the second driving gear 22 and the second driven gear 51 to rotate, because the diameter of the second driving gear 22 is larger than that of the second driven gear 51, the second driving gear 22 rotates for one week to drive the second driven gear 51 and the impeller 8 to rotate for more than one week, and therefore the rotating speed of the impeller 8 and the delivery capacity of the centrifugal pump are improved. The problem that the existing centrifugal pump mostly adopts the mode of increasing the input voltage of the motor 2 to improve the rotating speed of the motor 2 so as to improve the conveying capacity of the centrifugal pump, and therefore the electric energy utilization efficiency is low is solved.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
