Application
Advantages of stainless steel electropolishing:
Inside has the same color inside and outside, strong light
retention, mechanical polishing can not make the notch flat.
Production has high efficiency and low cost.
(3) increase surface corrosion resistance, applicable to all
stainless steel.
Requirements for electroplating and polishing of stainless steel:
The power waveform is not strict, SCR type or high frequency
electroplating rectifier can be selected.
Electropolishing bath and supporting equipment (anode rod):
Rigid PVC plates are welded together. The three electrode bars on
the top of the bath are in the middle of the movable anode bar, and
then are connected with the anode (or positive pole), both sides
are used as cathode poles, and are connected with the power cathode
(negative pole).
stainless steel electropolishing process:
Stainless steel electrolytic polishing process: degreasing –
washing – anti rust – washing – electrolytic polishing – washing –
passivation – packaging.
Features
1. 0~10V, 4~20mA,PLC,Timer, Ampere-minute/hour counter, HMI can be
provided
2. Control mode: Local control or Remote control(the length of
cable is determined by customers)
3. Japan IGBT(the default choice) or Germany IGBT are adopted
4. After being phosphated, galvanized and plastic sprayed, the
chassis has excellent corrosion resistence function
5. Easy to operate and repaire
1. Cabinet
a: Adopting completely digitalized machining
b: Adopting cold rolled production of iron steel sheet, after phosphorization, zinc plating, plastic spray, the rectifier gets better structural
strength and anti-corrosion.
c: Reasonable structure design, isolated inverter design,
rectification part is convenient to disassemble and mend because of
its neat assembling.
d: Radiator gets better cooling effect because of its 1.5 times capacity.
2 Electric control system
a: The rectifier adopts full bridge phase-shifted soft switch
control, ensuring the lowest power loss of IGBT. The capacity of
IGBT become 3 times bigger.
b: The main transformer. It adopts amorphous core to increase transformer efficiency and cool transformer, and not only can lighten rectifier weight,
but also can strengthen rectifier stability and reliability. At its
elementary stage, it adopts series blocking capacitor.
c: Magnetic deviation automatic correction circuit is adopted and
the total power of magnetic core gets enlarged 1.5 times.
3 Schottky Barrier Diode
a: It has been expanded 4 times.
4 All the controlling boards get antiseptic treatment with imported
lacquer.
How to install rectifier
This is installation way for remote control rectifier. Not only
this way.
1. To connect copper bar with bath/tank
2. To ensure power supply/rectifier is grounded
3. To ensure there is enough water for water cooling type power
supply/rectifier
4. We advice that all rectifiers should be isolated to increase of
its life.
