It is rotationally connected in bearing block；Further include having multiple installation screws, multiple first nuts and multiple second nuts, the installation
Screw runs through third mounting hole, the second mounting hole, the second nut, the first mounting hole and the first nut one by one from back to front；Pump case
It is fixedly connected with the screw-thread fit of the second nut between rear end cap by installing screw, thus casing tight abutment is in pump case
Between rear end cap；It is fixedly connected with the screw-thread fit of the first nut between end cap and pump case by installing screw.
By above structure, the utility model realizes that the buffering of itself and liquid impurity connects by using the design of flexible blade
It touches, is not easy stuck impeller, ensure operating reliability and passability, and its end is designed to that semi-cylindrical structure is realized and increases it
The purpose of contact area between stator case forms good sealing effect.Additionally mounted screw concatenated simultaneously drive end bearing bracket,
Pump case, casing and rear end cap, without separately screw being used to install one by one, and the fine-tuning control of position of mounting hole, Aligning degree is more
Good, installation is more convenient.
Further, in flexible paddle pump described in the utility model, first mounting hole, the second mounting hole, third
Installation hole number is completely the same and is all no less than three.
Further, in flexible paddle pump described in the utility model, first mounting hole is equal around drive end bearing bracket center
Even distribution.
Further, in flexible paddle pump described in the utility model, the blade is made of rubber.
Further, in flexible paddle pump described in the utility model, the outer end of the fine tuning screw rod is equipped with cross recess
Hole.
The utility model has the beneficial effects that：
1, suction capacity is strong, and passability is good, even if there is impurity to enter in vane pump, is not easy to stuck impeller.
2, blade outer end portion uses circular-arc-shaped design, increases its contact area between stator case, sealing performance is notable
It is promoted.
3, drive end bearing bracket, pump case, casing and rear end cap are concatenated integrally, compared to biography simultaneously by the same installation screw
The separable assembled mode of system reduces the quantity of installation screw, simplifies installation steps.
4, micro-adjusting mechanism on rear end cap is set, the position of third mounting hole can be fine-tuned, it can be more precisely
Ensure coaxial state with the first mounting hole, the second mounting hole, it is inconvenient to avoid installing caused by mismachining tolerance.
