Problems solved by technology
[0002] The factory electrification test of the existing submersible motor can only carry out the simulation test with a shallow submersion depth (below 20 meters).
If the submersible motor is placed in a water pressure environment of 10MPa, the cable lead-out device of the submersible motor cannot withstand the pressure difference of 10MPa inside and outside the cavity, which will cause the cable to be extruded from the pressure vessel, and the cable will be damaged in a short time. Serious accidents such as wiring damage
[0003] At this stage, the factory test of submersible motors with deeper submersion depth can only be carried out under the condition of no power supply, and the factory test of water pressure resistance can not be realized under 100 meters of underwater live working state simulation.
This kind of test without power can not reach the real state of on-site operation, which makes the factory operation test and field operation have a large deviation

The invention discloses a test device for simulating the underwater operation of a submersible motor. The inner cylinder body is fixedly arranged inside the outer cylinder body, and a sealing head is fixedly arranged on the top surface of the inner cylinder body. The sealing head There are pressurization pipes and exhaust pipes on the top, and the inside of the inner cylinder is fixed with a bracket for fixing the submersible motor. The submersible motor is provided with three cable leads, and the three cable leads are respectively the same as the outlet One end of the device is connected. In the present invention, the parts of the three outlet devices located outside the head are connected to the A phase, B phase and C phase of the power supply. After the submersible motor is installed in the test device, the power supply is turned on to realize the charging of the submersible motor. Work, realize the simulation of the working state of the submersible motor at 100 meters underwater, and truly reflect the test of the submersible motor under real working conditions, so as to facilitate the improvement of the performance of the submersible motor.
Description
technical field [0001] The invention belongs to the technical field of submersible motors, in particular to a test device for simulating the underwater operation of a submersible motor. Background technique [0002] The factory electrification test of the existing submersible motor can only carry out the simulation test of the shallower submersion depth (below 20 meters). If the submersible motor is placed in a water pressure environment of 10MPa, the cable lead-out device of the submersible motor cannot withstand the pressure difference of 10MPa inside and outside the cavity, which will cause the cable to be extruded from the pressure vessel, and the cable will be damaged in a short time. Serious accidents such as wiring damage. [0003] At this stage, the factory test of the submersible motor with a deeper submersion depth can only be carried out under the condition of no power supply to withstand the water pressure factory test, and it is impossible to realize the simula...
