28kHz 100W Industrial Ultrasonic Cleaning Transducer

Model: GB-4528-4SH
Type: Bolt-Clamped Langevin Transducer (Horn Type)
Main Applications: Ultrasonic Cleaning Machines, Immersible Ultrasonic Transducer Packs, Industrial Cleaning Tanks

1. Product Features & Advantages

• High Energy Conversion: High electroacoustic conversion efficiency with low heat generation during continuous operation.
• Large Amplitude Output: Horn-type flared radiating structure provides strong acoustic amplitude and uniform cavitation.
• Stable Performance: Low resonance impedance and high mechanical stability maintain consistent acoustic output.
• Direct Supply: Factory-manufactured components ensure cost-effectiveness and fast delivery.

Structural Highlights:

• Frosted / Ground Base Surface: The radiating base is ground with a fine abrasive wheel to increase surface roughness, providing secure adhesive bonding to stainless steel tanks.
• Beveled Horn Geometry: The smooth flared profile optimizes acoustic wave transmission, enhancing output amplitude and operating stability.
• Insulation Design: High-temperature and corrosion-resistant insulation adhesive ensures high dielectric strength and electrical reliability.

Tank Mounting Stud Options

• Capacitor Discharge Stud (CD Stud): Welded to the stainless steel plate using a stud welding gun.
• Arc-Welded Stud: Welded to the stainless steel plate using drawn-arc welding.

3. Exploded Component Structure

1. Stainless Steel Back Mass: Provides mechanical mass and reflects acoustic energy toward the front radiating surface.
2. High-Strength Hexagon Socket Bolt: Clamps the entire assembly and applies uniform mechanical pre-stress to the ceramics.
3. High-Performance Piezoelectric Ceramics (PZT): Converts high-frequency electrical energy into mechanical vibration.
4. Copper Electrode Plates: Positive and negative polarity connecting tabs.
5. Insulation Tube / Bushing: Electrically isolates the central bolt from the ceramic rings.
6. Frosted Aluminum Front Mass: Flared radiating horn engineered for adhesive bonding directly to cleaning tanks.

4. Tank Installation Guidelines

Installation Steps

1. Positioning: Align the transducer over the pre-welded threaded stud on the stainless steel tank bottom.
2. Applying Adhesive & Fastening: Apply specialized bonding adhesive evenly across the contact area, then screw the transducer onto the stud.
3. Torque Tightening: Tighten the transducer to press out excess adhesive and eliminate trapped air bubbles.
4. Cleaning: Wipe away extruded adhesive around the base perimeter.
5. Curing: Allow the adhesive to cure completely before wiring and liquid immersion.

Critical Installation Criteria

• Perpendicular Alignment: Mounting studs must be welded strictly perpendicular to the tank plate. A tilted stud causes uneven stress and acoustic loss.
• Flush Contact: The transducer base must sit flat against the tank plate without any clearance or gap. Verify that the stud length does not bottom out inside the threaded hole before the radiating base contacts the tank plate.

5. Wiring Instructions

• Circuit Configuration: All ultrasonic transducers must be connected in parallel.
• Cable Specification: Use high-temperature wire with a conductor cross-section of 1.5 mm².
• Polarity Connections:
  • Positive (+): Connect the middle electrode plate between the ceramic rings to the high-voltage (Red) output of the ultrasonic generator.
  • Negative (−): Connect the outer electrode plates to the ground (Black) output / metal housing.

6. Transducer Product Range

A comprehensive selection of industrial ultrasonic transducers is available in various frequencies, dimensions, and power ratings to match different cleaning tank dimensions and load requirements.

7. System Applications

• Ultrasonic Immersible Transducer Packs: Submersible modular transducer boxes for retrofitting or large tanks.
• Standard Ultrasonic Cleaning Machines: Integrated benchtop and floor-standing industrial cleaners.
• Multi-Tank Automatic Ultrasonic Lines: Multi-transducer array setups for precision parts cleaning, degreasing, and surface treatment.

8. Manufacturing & Quality Control

• Raw material selection and CNC machining.
• Assembly under controlled pre-stress tightening torque.
• 100% parameter testing with digital impedance analyzers before packaging.

9. Packaging & Protection

• Inner Protection: Custom slotted foam matrix trays with individual protective bags prevent physical contact and surface scratches.
• Outer Packaging: Reinforced multi-layer corrugated export cartons packed for secure domestic and international freight.
