It is internal.
Electrical heating, which hinders, to exchange heat after silk 4 heats up with the conductive fluid inside heat exchanging chamber 6, and conductive fluid is again to the phosphorus inside Phosphating Slot 5
Change liquid heating, effectively avoiding the problem that electrical heating resistance silk 4 directly heats leads to 5 non-uniform temperature of Phosphating Slot, works as temperature sensor
15 when detecting phosphating solution temperature higher than setting maximum value, sends the signal to controller, and controller closes electrical heating and hinders silk 4,
Conversely, when temperature sensor 15 detects phosphating solution temperature less than setting minimum value, controller starts electrical heating resistance silk 4 and transports
Row, during heating, air inlet pipe 18 convey gas to isocon 16, and gas is sprayed by nozzle 14, accelerates disturbing for phosphating solution
Stream so that temperature is more uniform, and the piezoelectric element of ultrasonic transducer 17 can convert electric energy to strong high-frequency vibration, this
Kind frequency and amplitude very little, about several microns to tens microns, but there is very high acceleration, when multiple energy converters are applied in same frequency
When rate and potential voltage, high-frequency reciprocating vibration is just formed with tank liquor, and propagated in tank liquor, cavitation is generated under felicity condition and is made
With, cavitation is easily generated in solid-liquid phase interface, has the very strong ability for penetrating solid and liquid, thus to being immersed in liquid
Workpiece surfaces externally and internally under face can carry out extraordinary cleaning with physical action, and phosphating reaction can be promoted equably to carry out；Ultrasonic wave
Strong stirring power make the hydrogen generated during phosphating reaction accelerate to be detached from workpiece surface, to make workpiece surface always with newly
Fresh solution contact, makes workpiece surface polarization phenomena thoroughly disappear.
After phosphatization, before emptying phosphating solution, start electric cylinder 7 and residual cake valve 12, electric cylinder 7 using controller
Slag discharge plate 10 is pushed to push phosphatization slag to scum pipe 13 by cylinder rod 19, phosphatization slag is discharged by scum pipe 13, is realized automatic
