Abstract
A lead screw type water pump impeller detacher relates to the technical field of impeller detaching tools and comprises a lead screw fastened into a threaded hole in the center of a pull seat, three pull jaws are uniformly distributed on the outer circumference of the pull seat, the outer end of each pull jaw is provided with a plastic washer, and a handle is disposed at the top end of the lead screw. The lead screw type water pump impeller detacher can easily detach an impeller without damaging to a pump shaft and the impeller, is convenient in detachment, and increases working efficiency.
Description
Technical field
The utility model relates to the impeller demolition technical field of tools.
Background technique
Centrifugal water pump is industrial widely used a kind of conveying equipment.But this pump is generally wanted earlier impeller is removed in maintenance process, owing to there is not special-purpose impeller demolition instrument, present method for dismounting generally is with crowbar with the impeller sled down, dismantle very difficultly, and causes the damage of impeller or pump shaft even damage easily.The impeller that also has is because corrosion is more serious, and impeller is not torn open not got off, and can only use the method for gas cutting, and it is destroyed and pump could be disintegrated, and causes scrapping of pump shaft and impeller.
Summary of the invention
The technical problems to be solved in the utility model is: the utility model has overcome shortcoming of the prior art, a kind of leading screw type water pump vane replacer is provided, this leading screw type water pump vane replacer can be pulled down impeller at an easy rate, and pump shaft and impeller can damaged yet, convenient disassembly is increased work efficiency.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of leading screw type water pump vane replacer, comprise leading screw, leading screw screws in the screw at pulling seat center, is evenly equipped with three pulling claws on the excircle of pulling seat, the pulling claw outer end is provided with plastic washer, and the top of leading screw is provided with handle.
The beneficial effects of the utility model are: because this leading screw type water pump vane replacer employing is to use leading screw under the effect of pulling claw, impeller is pulled out from pump shaft, make that the dismounting impeller is very convenient, and pump shaft and impeller can damaged yet, improved working efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural drawing of the utility model leading screw type water pump vane replacer.
Fig. 2 is the partial sectional view of the A-A direction of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, a kind of leading screw type water pump vane replacer comprises leading screw 1, and leading screw 1 screws in the screw at pulling seat 3 centers, is evenly equipped with three pulling claws 2 on the excircle of pulling seat 3, and pulling claw 2 outer ends are provided with plastic washer 4, and the top of leading screw 1 is provided with handle 5.When dismantling water pump vane, three pulling claws 2 of this instrument are put into the spiral case of impeller, three plastic washers 4 withstand impeller, adjust balance, the screw of then leading screw 1 being aimed at pulling seat 3 centers screws in, leading screw 1 is withstood on the center hole of pump shaft, continue to screw in leading screw 1, impeller is just easily split following under the effect of pulling claw 2.During rotating threaded shaft 1, can hold rotation on handle 5, convenient like this.This leading screw type water pump vane replacer can be pulled down impeller at an easy rate, and pump shaft and impeller can damaged yet, and convenient disassembly is increased work efficiency.
