The separate extraction chamber system is the optimal solution that divide the different products into two independent cabins for cleanliness testing; So as to avoid the mutual pollution caused by different extraction methods of different products in a cabin, in this way to make sure all test following up the ISO 16232 and VDA19.1 analysis processes.
| Description |
Model
-CLS-S
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.

| 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.
| Pressure/flow rate flushing |
The components are inspected with a spray gun set at a certain pressure or flow rate, angle, and then extracted and collected residual particles. The spray cleaning pressure (National standard) or flow rate (European standard) can be set, and the operation can be carried out in a quantitative or timed manner with a set flow rate. The specific requirements are based on the cleanliness operation specifications of different components.
