Description

Puller device for dismantling impeller

Technical Field

The utility model belongs to the technical field of draw horse device, concretely relates to draw horse device for demolising impeller.

Background

In motor equipment, mechanical equipment, air blowing equipment or water pumps required by industrial production, impellers are often arranged, and need to be replaced when damaged, but the impellers are difficult to separate from a shaft. The traditional impeller pulling device generally adopts a 2-claw or 3-claw puller (an electric hydraulic jacking multi-purpose machine) to pull out the impeller sleeved on a shaft, but gaps between certain impellers and the edge of a pump body are small, a claw type clamping mode of the puller cannot find a fixed point on an impeller wheel disc, and the traditional claw type pulling device cannot be used. Therefore, a novel puller device for removing the impeller is needed to solve the problems and meet the requirements of people.

An object of the utility model is to provide a draw horse device for demolising impeller to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a draw horse device for demolising impeller, draws horse, L type mold insert including two claws, two claws draw the horse including drawing the horse ejector pin and establishing two claw hooks on horse ejector pin both sides, two millimeter holes have been seted up on the L type mold insert, two claws draw the horse to correspond there is the turbine pump body, and the turbine pump body is equipped with the turbo pump motor, installs the rim plate impeller on the turbo pump impeller shaft of turbo pump motor, set up the millimeter screw hole that matches with millimeter hole on the rim plate of rim plate impeller.

Preferably, the L-shaped insert is installed behind the wheel disc impeller, keeps the lug outwards arranged and is matched with the claw hook of the two-claw puller.

Preferably, a pump liquid inlet and a pump liquid outlet are formed in the turbine pump body.

Preferably, the turbine pump body and the wheel disc of the wheel disc impeller form a cavity, and the impeller is located in the cavity.

Preferably, the 8 mm screw holes 5 and the 10 mm screw holes 11 are symmetrical to the axis of the turbine pump impeller shaft 4, and the puller ejector rod 101 corresponds to the axis of the turbine pump impeller shaft 4.

The utility model discloses a technological effect and advantage: this a draw horse device for demolising impeller, convenient to use, the technique is reasonable, both uses manpower sparingly, and the power that can bear is bigger, and intensity is higher, is applicable to turbo pump, self priming pump, and water ring vacuum pump's impeller is demolishd.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a draw horse device for demolising impeller as shown in figure 1, figure 2, draw horse 1, L type mold insert 3 including two claws, two claws draw horse 1 including drawing horse ejector pin 101 and establishing two claw hooks 102 on horse ejector pin 101 both sides, two 10 millimeter holes 11 have been seted up on L type mold insert 3, two claws draw horse 1 to correspond there is the turbine pump body 6, and the turbine pump body 6 is equipped with turbine pump motor 10, installs rim plate impeller 7 on turbine pump impeller shaft 4 of turbine pump motor 10, set up 8 millimeter screw hole 5 with 10 millimeter hole 11 matches on rim plate impeller 7's the rim plate.

Specifically, the L-shaped insert 3 is mounted on the wheel disc impeller 7, and the holding lug is disposed outward and matched with the claw hook 102 of the two-claw puller 1.

Specifically, a pump liquid inlet 8 and a pump liquid outlet 9 are arranged on the turbine pump body 6.

Specifically, the turbine pump body 6 and the wheel disc of the wheel disc impeller 7 form a cavity, and the impeller is located in the cavity.

Specifically, 8 millimeter screw hole 5, 10 millimeter hole 11 and 4 axle symmetries of turbine pump impeller shaft, and draws horse ejector pin 101 and 4 axle correspondences of turbine pump impeller shaft.

The working principle is as follows: before the puller device for removing the impeller is detached, two 8-millimeter screw holes 5 are drilled on a wheel disc of a wheel disc impeller 7, the 8-millimeter screw holes 5 are symmetrical to the axis of the impeller, an L-shaped lug of the L-shaped insert 3 is outwards ensured by fixing the L-shaped insert 3 on the impeller 7 by using 8-millimeter screws, a claw hook 102 of the two-claw puller 1 well hooks the lug of the L-shaped insert 3, a puller ejector rod 101 of the two-claw puller 1 is aligned with a turbine pump impeller shaft 4, the puller ejector rod is slightly screwed until the impeller 7 is completely removed from the turbine pump impeller shaft 4, and only the L-shaped insert 3 and the turbine pump impeller shaft 4 on the impeller 7 are stressed in the whole shaft removing process, so that blades, bearing machine seals and the like cannot be damaged.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
