60W 28kHz Horn Type Ultrasonic Cleaning Transducer for DIY Metal Parts Degreasing Tanks Immersible Packs and Cleaner Equipment Systems

GB-3828-4SH Industrial Ultrasonic Cleaning Transducer (28 kHz / 60 W)

Product Overview

The GB-3828-4SH is a bolt-clamped Langevin horn-type piezoelectric ultrasonic transducer designed for heavy-duty industrial cleaning systems. Operating at a resonance frequency of 28 kHz with a 60 W power rating, it generates high-intensity acoustic cavitation to dislodge oils, heavy grease, scale, and carbon deposits from metal parts, precision molds, and industrial components.

Performance Characteristics

• High Conversion Efficiency: Minimizes dielectric losses and converts electrical input to mechanical vibration efficiently.
• Large Output Amplitude: Horn profile amplifies acoustic stroke for deep-cavitation cleaning.
• Low Thermal Dissipation: Low resonant impedance reduces heat buildup during continuous operation.
• Stable Output: Maintains stable frequency and output power under sustained industrial loads.
• Cost Effective: Durable material selection extends operating lifespan and lowers maintenance costs.
• Factory Direct Supply: Direct manufacturing ensures stable batch quality and prompt fulfillment.

Design & Construction Highlights

• Precision Ground Radiation Base: The bottom face is precision-ground with a fine abrasive wheel to create uniform surface roughness, maximizing epoxy bond adhesion to stainless steel tanks.
• Acoustic Horn Geometry: The smooth flared profile optimizes acoustic impedance matching between the transducer and the cleaning fluid, increasing wave amplitude.
• High-Grade Encapsulation: High-temperature, corrosion-resistant insulating adhesive seals internal components, preventing moisture intrusion and electrical breakdown.

Technical Specifications

Component Architecture

1. High-Strength Hex Socket Pre-Stress Bolt: Clamps ceramic rings under precise mechanical pre-stress.
2. Stainless Steel Back Mass: Provides acoustic impedance mismatch to direct ultrasonic energy forward.
3. Piezoelectric Ceramic Rings (PZT): High-stability piezoelectric elements for continuous mechanical oscillation.
4. Copper Electrode Plates: High-conductivity terminals for positive and negative lead connections.
5. Insulating Sleeve: Prevents voltage arcing between the center bolt and ceramic stack.
6. Aluminum Front Radiation Horn: Lightweight acoustic transmitter with a ground mating surface for tank bonding.

Tank Installation Guidelines

1. Surface Cleaning: Degrease and abrade the tank bottom at each mounting position.
2. Stud Welding:
   • Weld studs using a capacitor-discharge (CD) stud welder or standard arc welder.
   • Studs must be positioned strictly perpendicular (90°) to the tank plate. Angled studs prevent full contact and cause premature failure.
   • Ensure no weld spatter or raised flash remains around the stud root that could create an air gap.
3. Adhesive Application: Coat the ground face of the transducer with high-strength structural epoxy.
4. Mechanical Fastening: Thread the transducer onto the stud, torque it down firmly, and wipe away excess adhesive around the perimeter.
5. Curing: Allow the epoxy to cure fully prior to wiring or water testing.

Electrical Wiring Specifications

• Connection Scheme: Connect multiple transducers in parallel.
• Conductor Sizing: Use copper wire with a cross-sectional area of at least 1.5 mm².
• Polarity Arrangement: Connect the positive (+) lead to the center terminal tab and the negative (-) lead to the outer/ground terminal tabs.
• Electrical Safety: Ensure all wiring is insulated from the tank chassis to prevent short circuits.
