Problems solved by technology

[0007] 1. The domestic connector pull-off force test device does not involve the water pressure environment, and is not suitable for underwater electrical connector testing;
[0008] 2. Domestic pull tests are mostly static load tests. Only a few test devices involve pull-off at a certain speed, but the test speed range is small. However, the pull-off speed has a greater impact on the pull-off force. Occasions with a high take-off speed cannot meet the test requirements;
[0009] 3. The domestic pull-off force test device can measure the pull-off force of the connector within 2500N, which cannot meet the actual working conditions with large pull-off force;
[0010] 4. Foreign underwater connector testing devices cannot test the transient pull-off force of underwater connectors. On the one hand, the transient pull-off force index can judge the reliability of the electrical connector connection. , which has guiding significance for calculating the pulling force exerted by the electrical connector;
[0011] 5. The speed adjustment is manual adjustment, and the degree of automation is low

Abstract

The invention provides an electric coupler pulling-out force testing device and a method thereof. The electric coupler pulling-out force testing device is composed of a hydraulic system, a water pressure control system and a measurement and control system. The hydraulic system is composed of a gear pump, solenoid directional valves, a pilot overflow valve, an energy accumulator, a proportional throttle valve, an oil cylinder, an air cooler, filters and a pressure gage. The water pressure control system is composed of a pressure testing pump, a variable frequency motor, stop valves, energy accumulators, pressure gages, pressure sensors, a pressure barrel, a motor frequency converter, a PLC and a touch screen. The measurement and control system is composed of pressure sensors, a displacement sensor, an industrial personal computer, a data acquisition card, a relay module and an isolation module. According to the testing device, a water pressure environment with the pressure ranging from 0 MPa to 6 MPa is built for electric coupler pulling-out, it is guaranteed that the pressure fluctuation range is within 5% in the electric coupler pulling-out process, the pulling-out speed within the range from 0 m / s to 1 m / s and the maximum pulling-out force not smaller than 5,000 N are provided, and the pulling-out force at the moment of electric coupler disengagement is calculated out.

Description

technical field [0001] The invention relates to an electric connector pull-off force test device and a method thereof, and belongs to the technical field of hydraulic control test systems. Background technique [0002] Underwater connectors are indispensable electronic components in marine and other underwater engineering and weaponry systems. Under the continuous application of electrical equipment. At present, with the development of offshore oil and the continuous development of weapon combat systems to deep sea areas, underwater connectors are more useful. Taking offshore oil development as an example, from 2013 to 2017, the investment in deep-water oil development will account for more than 50% of the total investment in offshore oil and gas development. Major oil companies have turned their attention to the deep-sea field where the level of development and exploration is still very low, prompting This has led to the increasing attention of underwater connectors and t...
