CLS300U Technical Cleanliness Cabinet with Ultrasonic Baths

CLS300U Technical Cleanliness Cabinet with Ultrasonic Baths

CLS300U ultrasonic baths are especially suitable for extracting contamination from small components with complex structures, micro-holes / blind holes / narrow slits, and high precision requirements that are difficult to handle individually because they can be sampled in bulk. By directly or indirectly applying ultrasonic waves to liquids and particles contaminants, the adhesion of insoluble particles contaminants is disrupted, causing them to disperse in the liquid to collect particles on the filter membrane.

CLS300U ultrasonic cleanliness cabinet with 300mm*150mm(L*D) ultrasonic bowl for low blank value around 50μm, CLS300U with pressure-rinsing, spray cleaning, ultrasonic cleaning, membrane sample preparation (particle extraction).

Description

Model

-CLS300U

Purpose of the device

-Used for cleaning and extracting particles from components.

Equipment principle

-Wet extraction: Using a specified liquid medium, flushing the surface of components with a standard nozzle within a set pressure range to separate solid particles from the components, which are then collected on the detection filter membrane.

-Ultrasonic extraction:By utilizing the cavitation effect of ultrasonic waves in liquids, bubbles are generated in the liquid. These bubbles come into contact with the surface of the product and collapse, thereby disrupting insoluble attached particulate contaminants, causing them to disperse in the solution, and ultimately achieving the effect of cleaning particulate contaminants from the surface of the parts.

Equipment advantages

-The equipment has real time display of equipment working status, continuously adjustable parameters.

-After cleaning the parts, a filter membrane sample can be obtained directly to reduce the retention time of particulate contamination in the cleaning agent; which standardizes the cleanliness testing control process and improves testing efficiency.

-The operating space for cleaning parts is relatively independent, with a built-in air laminar flow system to purify the cleaning operating environment, effectively isolate the cleaning area and external environment, and build a clean operating platform for cleaning and testing.

-Reference standards for equipment design and operation methods:VDA19.1 2015 edition, ISO16232 2018 edition, and customer defined standards.

Main function

Laminar air purification

The equipment integrates an air supply device with air circulation filtration function. Create a clean space with a level of 1000 or 100 in the cleaning work area (with a standard laboratory air level of millions), providing a good cleaning operating environment for component cleanliness testing, and reducing the impact of external environment on testing results.

 

Ultrasonic automatic cleaning

Ultrasonic vibration cleaning utilizes the direct and indirect effects of ultrasonic waves' cavitation, acceleration, and rectilinear flow in liquids on the liquid and contaminants. It generates pressure of 10¹²-10¹³ Pa and local temperature adjustment around the bubbles, which destroys the adhesion of insoluble particulate contaminants, causing them to disperse in the solution. Ultimately, it achieves the effect of cleaning particulate contaminants from the surface of components. The cleaning effect is superior to pressure cleaning, with better cleaning uniformity. This function is integrated into the equipment, enabling fully automatic ultrasonic cleaning and a higher degree of automation in cleaning and detection.
