Disclosure of Invention
In view of the fact that the existing testing device cannot test the submersible motor with one end of the rotor arranged in the casing, the technical problem to be solved by the utility model is as follows: the testing device special for the performance test of the submersible motor can reduce production cost and ensure product tightness.
In order to achieve the above object, according to one aspect of the present utility model, the present utility model is achieved by the following technical means: a submersible motor performance testing apparatus comprising: the testing device comprises a testing shaft head, wherein the lower end of the testing shaft head can be movably fixed with a rotor, the testing device further comprises a rotary sealing piece and a pressing plate, the rotary sealing piece is tightly sleeved on the testing shaft head for rotary sealing, the outer side of the rotary sealing piece is matched with a bearing seat of a submersible motor, the pressing plate is also tightly sleeved on the testing shaft head and is arranged at the upper end of the rotary sealing piece, and meanwhile, the pressing plate is movably fixed with the bearing seat of the submersible motor.
Further, the testing shaft head is a ladder cylinder, and the diameter of the upper end of the testing shaft head is smaller than that of the lower end of the testing shaft head.
Further, a washer is arranged at the step of the test shaft head, and the washer is arranged at the lower end of the rotary sealing piece.
Further, the upper end of the test shaft head is provided with a spline, and the test shaft head is connected with the motor tester through the spline.
Further, the lower end of the test shaft head is provided with an inner flat square, and the inner flat square is fixedly connected with an outer flat square of the motor rotor in an inserting mode.
Further, the pressing plate and the bearing seat of the submersible motor are connected through a plurality of fixing screws.
Compared with the prior art, the utility model has the advantages that the pressing plate is movably fixed on the motor shell through the fixing screw, and the testing shaft head is movably fixed with the motor rotor, so that after the submersible motor is tested, the pressing plate is replaced by the sealing cover plate through disassembling the fixing screw and is fixed with the bearing seat through the fixing screw, and the sealing problem of the submersible motor can not be influenced.
