CPC H05K 7/20345 (2013.01) [H05K 7/20327 (2013.01); H05K 7/20381 (2013.01)] | 6 Claims |
1. An evaporative cooling logic control method of an inductive vibration device, comprising the following steps:
(1) running a test:
S1, starting the vibration device and acquiring data;
S2, displaying an effective output current by a power amplifier, and judging whether the effective output current is greater than 600 amperes;
(2) when the effective output current is greater than 600 amperes:
S1, opening a water inlet solenoid valve, performing automatic timing by a time relay, and enabling purified water to flow into an air pipe;
S2, after the water inlet time is reached, closing the water inlet solenoid valve, opening an air inlet solenoid valve, performing automatic timing by an air inlet relay, enabling a high-pressure airflow to enter the air pipe, and closing the air inlet solenoid valve when the time is reached;
S3, spraying and pressurizing the purified water, by the high-pressure airflow entering the air pipe, to form misty water droplets, and taking away heat on a surface of a moving coil induction ring;
when the effective output current is less than or equal to 600 amps:
S1, closing the water inlet solenoid valve and the air inlet solenoid valve, and continuing the test; and
monitoring a temperature of the moving coil induction ring by an infrared temperature sensor:
S1, when the temperature of the moving coil induction ring is lower than 260 DEG C., enabling the moving coil induction ring to work normally;
S2, when the temperature of the moving coil induction ring is greater than 260 DEG C., enabling heat to accumulate in a vibration table quickly, wherein the moving coil induction ring has a low intensity at this high temperature, which affects a normal use of the vibration table, and the power amplifier is automatically shut down to protect the vibration table.
