High‑Uniformity Ultrasonic Spray Nozzles – Non‑Clogging Coating Type

This ultrasonic atomizing nozzle features a narrow spray width. Built on ultrasonic atomization technology, it incorporates a specially optimized converging flow channel to evenly focus carrier gas flow. This compresses ultrasonically atomized liquid mist into a concentrated spray pattern, effectively reducing the overall spray coverage of the ultrasonic nozzle.

 

Thanks to its narrow spray width, this focused ultrasonic nozzle is ideal for a wide range of small‑to‑medium spray applications. It serves as a complementary solution to FUNSONIC's wide‑swath ultrasonic spray nozzles, and addresses nearly all flat‑surface spraying requirements.

 

Typical use cases include fuel‑cell coating, specifically membrane‑electrode spraying for proton‑exchange‑membrane fuel cells. Catalyst dispersions (e.g., platinum‑carbon catalyst) are ultrasonically atomized and deposited onto proton‑exchange membranes to produce uniform, dense membrane‑electrode assemblies.

 

Benefiting from its mist‑converging and focused‑spray characteristics, this ultrasonic nozzle delivers high‑precision spraying over confined areas. It is also suitable for surface coating of medical‑device components, including pharmaceutical‑layer deposition.

 

 

 

1. Poor Atomization Performance

Causes: Nozzle blockage, excessive liquid viscosity, vibrator failure

Solutions:

Clean the nozzle regularly to remove internal impurities and eliminate blockages.

Inspect the liquid formula and adjust the viscosity to meet operational requirements if needed.

Check the vibrator status and replace faulty vibrators in a timely manner.

 

2. Nozzle Leakage

Causes: Poor sealing performance, nozzle damage, aging of wearing parts

Solutions:

Inspect the sealing condition of the nozzle and connecting pipelines, and replace worn or damaged sealing rings when necessary.

Examine the nozzle body thoroughly; replace the nozzle immediately if any damage is detected.

 

3. Vibrator Failure to Operate

Causes: Power supply interruption, damaged vibrator components

Solutions:

Check the power cord and power plug to ensure stable and normal power supply.

Verify the working state of the vibrator and perform replacement if it malfunctions.

 

4. Abnormal Excessive Noise

Causes: Loose installation of vibrator or nozzle, foreign matter inside the nozzle cavity

Solutions:

Check all connecting and mounting parts, and fasten any loose components.

Clean the internal cavity of the nozzle completely to remove foreign matter that causes abnormal noise.

 

5. Overly Large Atomized Particles

Causes: Improper nozzle model selection, mismatched ultrasonic operating frequency

Solutions:

Select a matched nozzle model according to the working conditions and verify the nozzle aperture specification.

Calibrate and adjust the ultrasonic frequency parameters to the optimal working range.

 

6. Unstable Liquid Flow Rate

Causes: Insufficient liquid supply, blocked or leaking liquid delivery pipelines

Solutions:

Ensure continuous and stable liquid supply to the equipment.

Inspect the liquid pipelines, clear internal blockages, and replace damaged pipeline accessories.

 

7. Circuit Abnormality

Causes: Circuit short circuit or open circuit, controller operational failure

Solutions:

Check all circuit wiring connections to rule out short circuits and open circuit faults.

Inspect the operating status of the controller, and repair or replace the controller as required.
