Degree sensor（10）, liquid level sensor（11）, and pressure sensor（12）Data uploaded to by ethernet communication module
Touch-screen（8）On, shown in real time；
Step 2, pass through touch-screen（8）To when the seawater atomizing pressure of anticorrosive paint seawater corrosion resistance test device, atomization splash
Between, splash interval time and test cycle number of times carry out parameter setting；
Step 3, pass through touch-screen（8）The startup of control anticorrosive paint seawater corrosion resistance test device；
Step 4, PLC control unit（9）Receive from touch-screen（8）After the parameters of setting, constant-pressure tank is detected first（4）
On pressure value, then by adjust frequency converter（13）To adjust sea water pump（3）Power, and then adjust constant-pressure tank（4）Interior
Pressure reaches the pressure value of setting；
Step 5 and then, PLC control unit（9）According to atomization splash time, splash interval time and test cycle number of times
Test parameters setting value, by control magnetic valve（25）Be switched on and off, realize atomization splash break-make control；
Step 6, atomization splash during, PLC control unit（9）Real-time detection constant-pressure tank（4）Pressure change, and control
Seawater is atomized the constant of applied voltage test parameter；
Step 7 is while record opening for the seawater salinity during seawater is atomized applied voltage test, pressure change and atomization splash
Time beginning and end time；
If not up to the cycle-index for setting, return to step repeats above procedure to step 8 cycle-index；If reaching setting
Cycle-index, by touch-screen（8）By off-test, collect test data and generate test summary sheet.
