The invention provides a full-automatic detection device for the electrical property of an electromagnetic valve. The device comprises an industrial personal computer, a data acquisition case, a programmable control linear power supply, a voltage and current acquisition module, a switching power supply, a withstand voltage insulation tester, a digital multimeter, an photoelectric coupler matrix, arelay matrix and an electromagnetic valve clamping wiring terminal; through the design of the relay matrix, the device detects various properties of different types of various electromagnetic valveson the basis of guaranteeing the safety detection of the electrical property of the electromagnetic valve, the simplest design of the relay matrix is realized, all the test programs of the valve are finished through only one cable clamping of the tested valve and the device, and the device is widely suitable for various types of valves, and solves the technical problems that the various test programs of the existing electromagnetic valve are mutually independent and a product needs to be wired again before each test.
Description
technical field [0001] The invention relates to a fully automatic detection device for the electrical performance of a solenoid valve. Background technique [0002] The purpose of building the test device is to improve the automation level of the test, improve work efficiency and reduce test personnel. When the current solenoid valve is doing electrical performance test, it is necessary to temporarily build a test system, use a digital multimeter to measure the coil resistance, conduction resistance and coil temperature rise inspection, use a withstand voltage tester to measure the withstand voltage, and use a megohmmeter to measure Insulation resistance, use mechanical pressure gauges, voltmeters, ammeters, slide wire rheostats and other instruments to measure the pull-in voltage, release current and response time. [0003] The above-mentioned various test items are independent of each other, and the product needs to be re-wired before each test. The preparatory work is lo...
