Problems solved by technology

[0002] At present, the test of water-cooled motor controller and water-cooled motor usually adopts the water pressure test method. For details, see figure 1 , specifically: including a water supply tank C1, a water pump C2, a test valve C3 and a pressure gauge C4, using this method for testing, only one workpiece to be tested can be tested at a time, and the efficiency is low; at the same time, the hydraulic test equipment During the installation and disassembly process, there will be water leakage in the water channel, which will have a great impact on the environment. At the same time, the reliability and safety of the product will cause hidden dangers.

Embodiment 1

[0038] see figure 2 , a system for detecting the sealing performance of motors and controllers and finding leaks, including a water supply pressure component 1, an air supply component 2, and a test pipeline 4 that communicates with the water supply pressure component 1 and the air pressure component 2 respectively. Part 3 and return line 5.

[0039] The water supply pressure component 1 includes a water storage tank 1.1, a high-pressure water pump 1.2 communicated with the water storage tank 1.1, a motor inverter 1.3 connected to the motor in the high-pressure water pump 1.2, and an outlet pipeline 1.21 arranged on the high-pressure water pump 1.2 The main water channel valve 1.4 on the top. The upper part of the water storage tank 1.1 is provided with an exhaust pipe 1.11.

[0040] The air supply component 2 includes an air compressor 2.1 and a main airway valve 2.2 arranged on the air outlet pipeline 2.11 of the air compressor 2.1.

[0041] The detection unit 3 includes...

Embodiment 2

[0065] A system for detecting the sealing performance of motors and controllers and finding leaks. The difference from Embodiment 1 is that it also includes a PLC controller; the motor in the high-pressure water pump 1.2, the motor frequency converter 1.3, and the main waterway valve 1.4. Air pump in air compressor 2.1, main airway valve 2.2, test valve A1, first solenoid valve A2, second solenoid valve A3, main test valve 4.1, pressure sensor B1, digital display pressure gauge B2, third solenoid The valve A4, the fourth electromagnetic valve A5 and the water delivery pump 5.1 are all connected to the PLC controller.

[0066] A kind of system that is used for the sealing performance detection of motor and controller and leak point of this embodiment is different from Embodiment 1 only in that the above-mentioned components are automatically controlled by the controller (by inserting a program inside the controller to carry out Automatic control) to realize automatic operation ...

Abstract

The invention provides a system for detecting sealing performance and searching leak points of a motor and a controller. The system comprises a hydraulic pressure supply part, an air pressure supply part and a detection part; the hydraulic pressure supply part comprises a water storage tank, a high pressure water pump, a motor frequency converter and a main valve of a water channel; and the detection part comprises one or multiple groups of single detection pieces. According to technical schemes of the invention, the system has the advantages that the total structure is simplified; one or multiple groups of single detection pieces can be used to detect multiple groups of to-be-detected workpieces simultaneously and improve the detection efficiency; the air pressure supply part is combined with the detection part to determine whether a product is qualified rapidly; the hydraulic pressure supply part is combined with the detection part to find a concrete leak point of the to-be-detected workpiece rapidly and provide convenience for subsequent maintenance; and the motor frequency converter is combined with the high pressure water pump, so that the hydraulic pressure can be adjusted according to requirements, and the practicality is high. The invention also provides a detection and leak point searching method of the system, the method is simplified in steps and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a system for detecting the sealing performance of motors and controllers and finding leaks and a method for using the same. Background technique [0002] At present, the test of water-cooled motor controller and water-cooled motor usually adopts the water pressure test method. For details, see figure 1 , specifically: including a water supply tank C1, a water pump C2, a test valve C3 and a pressure gauge C4, using this method for testing, only one workpiece to be tested can be tested at a time, and the efficiency is low; at the same time, the hydraulic test equipment During the process of installation and disassembly, the leakage of accumulated water in the water channel will have a great impact on the environment, and at the same time, the reliability and safety of the product will cause hidden dangers. [0003] After the research of technicians in this industry, there are other...
