Abstract

A special tool for maintaining a vacuum water pump motor comprises a screw rod and a fixed disc used for being connected with an impeller; the fixed disc is provided with a plurality of mounting holes which are in one-to-one correspondence with screw holes on the impeller, and bolts are arranged in the mounting holes to fix the fixed disc on the impeller to be disassembled; the fixed disc is also provided with a screw rod hole corresponding to the position of the shaft hole of the impeller, the screw rod is in threaded connection with the screw rod hole, one end of the screw rod penetrates through the screw rod hole to be abutted against a motor shaft in the shaft hole, and the other end of the screw rod is also provided with a handle for twisting the screw rod; and (4) screwing the screw rod, and separating the motor shaft from the impeller under the action of the thrust of the screw rod. The utility model discloses simple structure, low in production cost can effectually pull down the impeller when the water pump motor is maintained, has simplified operating procedure, has alleviateed operating personnel's working strength.

Description

Special tool for maintaining vacuum water pump motor

Technical Field

The utility model relates to a vacuum pump plant maintenance field especially relates to a vacuum pump motor maintains specialized tool.

Background

At present, the impeller needs to be removed in the maintenance process of the vacuum water pump motor, and because no special tool for removing the impeller is used at the present stage, an operator basically damages the stainless steel impeller seriously by adopting methods such as prying and knocking, and the stainless steel impeller is expensive. So that the cost and labor intensity are high in the original maintenance process.

Disclosure of Invention

In order to overcome the problems, the utility model provides a vacuum pump motor maintenance specialized tool which can conveniently dismantle the impeller and has small working strength.

The utility model adopts the technical proposal that: a special tool for maintaining a vacuum water pump motor comprises a screw rod and a fixed disc used for being connected with an impeller; the fixed disc is provided with a plurality of mounting holes which are in one-to-one correspondence with screw holes on the impeller, and bolts are arranged in the mounting holes to fix the fixed disc on the impeller to be disassembled; the fixed disc is also provided with a screw rod hole corresponding to the position of the shaft hole of the impeller, the screw rod is in threaded connection with the screw rod hole, one end of the screw rod penetrates through the screw rod hole to be abutted against a motor shaft in the shaft hole, and the other end of the screw rod is also provided with a handle for twisting the screw rod; and (4) screwing the screw rod, and separating the motor shaft from the impeller under the action of the thrust of the screw rod.

The mounting holes are uniformly distributed on the fixed disc and are positioned on the same circumference.

The utility model has the advantages that: simple structure, low in production cost can effectually pull down the impeller when the water pump motor is maintained, simplifies the operation step, alleviates operating personnel's working strength, can also reduce the utilization ratio that the down time improved the board simultaneously.

Detailed Description

The invention will be further described with reference to specific examples, but the scope of protection of the invention is not limited thereto:

referring to the attached drawings, the special tool for maintaining the motor of the vacuum water pump comprises a screw rod and a fixed disk 2 connected with an impeller, wherein the size of the fixed disk 2 is determined according to the model size of a stainless steel impeller, and when the diameter of the impeller is 50cm and the height of the impeller is 32cm, the diameter of the fixed disk 2 is 15cm and the thickness of the fixed disk is 5 com; a plurality of mounting holes 3 which correspond to screw holes on the impeller one by one are arranged on the fixed disk 2, and bolts 4 are arranged in the mounting holes 3 and the screw holes to fix the fixed disk 2 on the impeller to be disassembled; the fixed disc 2 is also provided with a screw rod hole 5 corresponding to the position of the shaft hole of the impeller, the screw rod is in threaded connection with the screw rod hole 5, one end of the screw rod penetrates through the screw rod hole 5 to be abutted against a motor shaft in the shaft hole, and the other end of the screw rod is also provided with a handle 1 for twisting the screw rod; by screwing the screw rod, the motor shaft is separated from the impeller under the action of the thrust of the screw rod.

The specific working mode is as follows: firstly, the fixing plate 2 is placed on the impeller to be disassembled, the bolt 4 penetrates through the mounting hole 3 to be fixedly connected with the impeller, the screw rod is screwed into the screw rod hole 5, the screw rod is enabled to be in a vertical state with a motor shaft in the impeller shaft hole, and the screw rod continues to rotate until the impeller is retracted from the motor shaft.

The embodiments described in this specification are merely illustrative of implementations of the inventive concepts, and the scope of the invention should not be considered limited to the specific forms set forth in the embodiments, but rather the scope of the invention is intended to include equivalent technical means as would be understood by those skilled in the art from the inventive concepts.
