60W 25kHz Horn Type Industrial Ultrasonic Cleaning Transducer for Heavy Oil Rust Removal Degreasing Tanks and Immersible Packs

GB-3825-4SH 25kHz 60W Industrial Ultrasonic Cleaning Transducer

The GB-3825-4SH is a horn-type piezoelectric ultrasonic transducer designed for industrial cleaning tanks, immersible transducer packs, and automated ultrasonic washing systems. Constructed with high-stability piezoceramics and industrial-grade aluminum alloy, it converts high-frequency electrical energy into uniform acoustic cavitation in liquid media.

Key Performance Advantages

• High Efficiency: Optimized acoustic matching reduces electroacoustic transmission losses.
• Large Amplitude: Horn-shaped radiating head enhances mechanical wave displacement.
• Low Heat Generation: Low dielectric loss and low impedance prevent thermal build-up.
• Stable Output: Uniform ceramic polarization ensures continuous, balanced acoustic energy.
• Cost Effective: Standardized factory production delivers competitive unit pricing.
• Fast Delivery: High production capacity ensures short fulfillment lead times.

Technical Specifications

Structural Features & Engineering Design

• Fine-Ground Radiating Base: The bottom contact surface is ground with a fine sandwheel to ensure optimal flatness and adhesion when bonded with epoxy resin to stainless steel (SUS) tank walls.
• Edge Flow Horn Profile: The smooth tapered horn contour increases conversion efficiency and directs cavitation energy forward into the bath.
• High-Temperature Insulation Seal: Coated with high-temperature, corrosion-resistant insulating adhesive to protect the internal ceramic rings against moisture, arcing, and corrosion.

Component Breakdown

• Pre-Stress Hex Bolt: High-tensile steel bolt maintains uniform mechanical pre-stress across the piezoceramic stack.
• Back Mass (Rear Block): High-acoustic-impedance backing mass reflects backward acoustic energy to the front radiation face.
• Piezoceramic Elements (PZT Rings): High-stability piezoelectric rings deliver robust electromechanical coupling and extended service life.
• Copper Electrode Plates: High-conductivity terminal lugs provide reliable power input connections.
• Insulating Sleeve: High-dielectric central tube prevents high-voltage electrical arcing between the central bolt and electrode tabs.
• Front Mass (Radiating Horn): Horn-shaped aluminum radiating body concentrates and amplifies ultrasonic cavitation.
• Sandwheel-Ground Bonding Base: Precision-ground contact face ensures maximum epoxy bonding strength.

Installation & Stud Welding Guide

Proper mechanical contact between the transducer face and the tank plate is required to prevent ceramic cracking and acoustic reflection.

Stud Types

• Sticker: Welded to the SUS plate using a capacitive discharge stud welding gun.
• Backnail: Welded to the SUS plate via standard arc welding.

Installation Instructions

1. Weld the threaded stud perpendicularly (90∘90^\circ90∘) onto the outer surface of the cleaning tank.
2. Ensure the base of the stud has no weld slag, and the tank surface is clean and degreased.
3. Apply epoxy adhesive evenly between the transducer radiating base and the tank wall.
4. Tighten the transducer firmly onto the stud so that the bottom surface contacts the metal plate completely without tilt or gap.

Electrical Wiring Instructions

• Circuit Configuration: All ultrasonic transducers in a multi-transducer tank must be connected in parallel.
• Lead Wire Specification: Use 1.5 mm² copper connecting wires.
• Electrode Polarity:
  • Positive Electrode (+): Connected to the middle copper terminal tab between the ceramic rings.
  • Negative Electrode (-): Connected to the outer copper terminal tabs touching the front/back metal masses (grounded to the tank structure).

Industrial Applications

The GB-3825-4SH 25kHz transducer is suitable for heavy-duty industrial degreasing, rust removal, engine block cleaning, and hardware surface treatment:

• Benchtop & Floor-Standing Ultrasonic Cleaners
• Ultrasonic Immersible Transducer Packs (Submersible Boxes)
• Multi-Stage Automated Ultrasonic Cleaning Lines

Manufacturing & Quality Inspection

• Precision Machining: CNC lathe turning guarantees dimensional consistency for all aluminum and steel masses.
• Automated Pre-Stress Assembly: Pneumatic torque tools apply exact pre-tightening force to protect ceramic rings.
• Impedance Analyzer Testing: 100% of units undergo digital resonance frequency, capacitance, and impedance testing.
• Thermal Aging: Transducers are cured in temperature-controlled ovens to stabilize internal stress and eliminate parameter drift.

Standard Export Packaging

Each transducer is sealed against moisture, set in custom-molded shock-absorbing foam trays, and packed into reinforced cartons for secure international shipping.
