50W 28kHz Horn Type Ultrasonic Cleaning Transducer for Automobile Engine Parts Degreasing Tanks and DIY Immersible Transducer Boxes

GB-28K-50W Industrial Ultrasonic Cleaning Transducer (28 kHz / 50 W)

Product Overview

The GB-28K-50W is a high-performance Langevin horn-type piezoelectric ultrasonic transducer engineered specifically for industrial cleaning applications. Operating at a resonance frequency of 28 kHz with a 50 W rated output, it delivers powerful acoustic cavitation to remove grease, heavy dirt, carbon deposits, and industrial residues from metal, glass, and composite workpieces.

Key Advantages

• High Conversion Efficiency: Optimized electro-acoustic energy conversion with minimal reactive loss.
• Large Output Amplitude: Horn-shaped radiation design delivers strong acoustic output.
• Low Heat Generation: Low resonance impedance reduces thermal buildup during continuous operation.
• Stable Continuous Performance: Consistent resonance frequency and amplitude stability under heavy industrial duty.
• Cost-Effective & Durable: High-grade materials ensure extended service life.
• Fast Delivery & Support: Direct factory manufacturing with guaranteed lead times.

Structural & Design Features

• Matte Ground Radiation Face: The radiating surface is ground with a fine abrasive wheel to create uniform micro-roughness, maximizing adhesive bonding strength to stainless steel cleaning tanks.
• Acoustic Horn Geometry: Precision-machined flared front mass optimizes impedance matching, amplifies vibration amplitude, and enhances acoustic radiation directivity.
• High-Grade Insulation Layer: Formulated with high-temperature, corrosion-resistant insulating adhesive to ensure electrical isolation and mechanical reliability.

Technical Specifications

Component Breakdown & Materials

1. High-Strength Hex Socket Bolt: Pre-stresses the piezoelectric stack for high mechanical stability.
2. Stainless Steel Back Mass (Top Cap): Provides acoustic impedance mismatch to reflect acoustic energy toward the front radiation face.
3. Piezoelectric Ceramic Stack (PZT): High-stability piezoelectric elements for continuous mechanical resonance.
4. Copper Electrode Plates: High-conductivity terminal tabs for stable electrical contact.
5. Insulating Sleeve: Prevents high-voltage breakdown between the internal bolt and electrode plates.
6. Aluminum Horn (Front Radiation Head): Lightweight acoustic transmitter with a ground radiation base for direct bonding to stainless steel tanks.

Installation & Mounting Guidelines

1. Surface Preparation: Clean and degrease the bonding area on the tank bottom.
2. Stud Welding:
   • Use a stud welding gun for capacitor-discharge (CD) weld studs, or arc welding for standard threaded studs.
   • Ensure the stud is welded strictly perpendicular (90°) to the plate. An angled stud will cause incomplete acoustic contact and transducer failure.
3. Adhesive Application: Apply high-strength epoxy adhesive evenly across the ground face of the transducer.
4. Torque Tightening: Screw the transducer onto the welded stud and tighten with a torque wrench to ensure complete contact without air gaps. Wipe off extruded excess glue.
5. Curing: Allow the epoxy adhesive to cure fully under room temperature or heated conditions before wiring and testing.

Electrical Wiring Diagram

• Connection Mode: Multiple ultrasonic transducers must be connected in parallel.
• Recommended Cable: Copper wiring with a minimum cross-sectional area of 1.5 mm².
• Polarity Identification: Connect the positive terminal to the central electrode plates and the negative terminal to the ground/casing electrodes.
• Safety Isolation: Verify that wiring is insulated from the metal tank chassis to prevent short circuits.

Multi-Frequency & Customization Support

A complete range of industrial transducers from 20 kHz to 200 kHz (power ratings from 35 W to 100 W) is available to match diverse generator frequencies, tank dimensions, and custom mounting configurations.
