BY‑100A Plasma Polishing Machine

1. Inner Tank Assembly

• Material: Double‑sided welded construction using 3 mm thick 316L stainless steel plate.
• Dimensions: L 620 mm × W 420 mm × H 600 mm
• Insulation: A 20 mm thick bakelite plate provides electrical isolation between inner tank and outer frame to prevent safety incidents.

2. Main Frame Assembly

• Material: Fabricated by welding 50 mm × 50 mm × 2.0 mm 304 stainless steel square tubes.
• Overall Dimensions: L 1200 mm × W 1080 mm × H 1680 mm
• Operation Panel: Bent and welded from 2 mm thick 304 stainless steel plate.
• Lifting Door: Outer frame welded from 40 mm × 40 mm × 1.0 mm 304 stainless steel square tubes; exterior covered with welded 1.2 mm bent 304 stainless steel sheets.
• Fixed Door Panel: Bent‑formed from 0.8 mm thick 304 stainless steel plate.

3. Transmission System

• Door Transmission: Φ30 linear guide rails are mounted on both sides of the lifting door. 30MULL linear sliders are fitted to the lifting door and engage with the guide rails. A frequency‑converter‑driven reduction motor transmits motion via 304 stainless steel chains to perform door lifting and lowering.
• Hanger Transmission: Φ30 linear guide rails are installed on both sides of the lifting frame. 30MUL linear sliders connect the lifting carriage to the guide rails. A frequency‑converter‑driven reduction motor drives 304 stainless steel chains for hanger up‑and‑down movement.
• General Transmission Description: An AC220 V frequency converter drives the reduction motor. The motor drives chains to actuate linear sliders for door opening/closing and hanger lifting/lowering.
• Hanger Stroke: 500 mm

4. Power Supply (Three‑Phase Full‑Bridge Rectification or Three‑Phase Inverter Rectification)

4.1 Three‑Phase Full‑Bridge Rectifier Power Supply (for materials except gold, silver and titanium) Operating Parameters

• Input: 3‑Phase AC 380 V ±5%
• Frequency: 50 Hz
• Output Power: 30 kW
• Output Voltage: Non‑adjustable (varies with mains supply)
• Max Output Current: 100 A
• Cooling Method: Air cooling

4.2 Three‑Phase Inverter Power Supply (for gold, silver and titanium materials) Operating Parameters

• Input: 3‑Phase AC 380 V ±5%
• Frequency: 50 Hz
• Output Power: 30 kW
• Output Voltage: 0‑400 V adjustable constant voltage
• Max Output Current: 100 A
• Cooling Method: Air cooling

5. Temperature Control System

Heating is provided by 316 seamless stainless‑steel heating tubes. Temperature sensors and AD temperature modules feed temperature readings to the PLC. The PLC controls contactors to regulate heating.

6. Water‑Level Control System

Float switches with micro‑switches send water‑level signals to the PLC. The PLC executes logic calculations to control the water‑make‑up solenoid valve.

7. Air Supply System

External compressed‑air source is connected. A throttle valve on the operation panel regulates airflow into the bottom of the inner tank for bath agitation.

8. Electrical & Control System

• Main control unit: Xinje PLC module.
• HMI: Weinview 7‑inch color touch screen.
• Operation modes: Full manual, fully‑automatic full‑process, or partial‑manual operation.
• Cabinet layout: Control cabinet and DC power cabinet are installed separately.

9. Site Layout Requirements

• Required floor‑space dimension: L 5000 mm × W 5000 mm × H 2800 mm (Includes overflow trough and loading/unloading workstation; excludes distillation drying tank and mixing tower footprint.)
• Workshop clear‑height requirement: Minimum 2800 mm.

10. On‑Site Utility Requirements

• Compressed air pressure: ≥ 6 kg/cm²
• Tap‑water supply: Flow ＞ 2 t/hr, pressure ＞ 3 kg/cm²
• Power supply: 3‑phase 5‑wire wiring; 380 V with voltage fluctuation ≤ ±5%.

11. Power Distribution & Exhaust

• Standard power cable: 3+2 core 16 mm²
• Main circuit‑breaker: 100 A (Note: If a distillation drying tank is fitted, upgrade to 3+2 core 25 mm² cable and 200 A main circuit‑breaker.)
• Exhaust system: Φ160 PP exhaust duct with either PP or stainless‑steel exhaust fan.
