Embodiment Construction

[0036] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0037] The submersible motor test device of this embodiment can test the motor 2 in a liquid environment. The liquid environment can be a low temperature liquid, a high temperature liquid, or a normal temperature liquid. In this embodiment, the motor 2 in a low temperature liquid environment is used. The test is described, for example, the motor 2 is in a low temperature environment of liquid nitrogen.

Abstract

The invention relates to the technical field of testing devices, in particular to a testing device for an immersed motor. The device comprises a barrel body, the motor, an indoor testing mechanism andan outdoor testing mechanism. The barrel body is internally provided with a containing cavity for containing liquid; the motor is installed in the containing cavity of the barrel body; the indoor testing mechanism is installed in the containing cavity and connected with the motor; the outdoor testing mechanism is installed at the outer side of the barrel body and connected with the indoor testingmechanism through sensing, and the indoor testing mechanism and the outdoor testing mechanism test the motor. The testing device for the immersed motor is suitable for testing of motor performance inlow-temperature liquid and has the advantages that the resources are saved, and testing is safer.

Description

Technical field [0001] The invention relates to the technical field of testing devices, in particular to a submersible motor testing device. Background technique [0002] Liquefied natural gas (LNG), as a clean energy source, has been widely used in various fields of life and industry. The transportation of LNG usually requires the use of low-temperature submersible pumps. The motor used in the pump is located in the pump and immersed in LNG. Work in cryogenic liquid LNG. The submersible low-temperature motor is the core component of the LNG submersible pump, and its operating performance directly affects the safety of LNG transportation. In order to accurately test the low temperature characteristics of the submersible motor, it is necessary to place the motor in a low temperature liquid environment for testing. [0003] Taking into account the flammability and explosiveness of LNG, in order to ensure safety, under normal circumstances, the performance test of submersible low-te...
