Vacuum Tube Double-frequency Induction Heating Equipment

We are offering vacuum tube double-frequency induction heating equipment.
Double-frequency in one equipment,include:super audio and high frequency.
Power:100kw,200kw
frequency:35khz,250khz
used in surface hardening of various gears,shafts,plates etc.
Vacuum tube hf induction heating equipment adapts vacuum tube as the key component of equipment and use scm system as the core to constitute the intelligent control system for voltage-regulating, oscillation and protection and widely used in quenching, brazing, melting, heat penetrating and so on fields.
circuit mode:
single loop with capacitance feedback (10 11)
three loop with inductance capacitance feedback (20 20 22)
single loop with inductance feedback（30 30 32）
high frequency and high voltage output (40 41)
the structure number is to distinguish the difference of feedback mode and vacuum tube's quantity in the same loop mode.
All equipment have the same part, we needn’t to make any mark on microcomputer control voltage adjustment, regulator and high-voltage silicon bridge rectifier. To places a letter“l” following the model number of equipments with a 12 phase rectifier and wave filter network.
adjustment and rectifier:
microcomputer controlled thyristor
voltage regulator is installed inside
the equipment.
voltage adjustment range: 0-100%.
precision of voltage stability: ＜±1%,
overload protection speed: 1/50s，using high
voltage silicon rectifier and choosing the low ripple
control electricity structure with 12 phase rectifier
and network wave filter.
