Technical Cleanliness Test Equipment

The equipment integrates pressure jet cleaning, on-line filtration & recovery of cleaning agent and circulating fine filtration. It enables synchronous operation of component cleaning and particulate contaminant filtration & recovery. Particulates stripped from component surfaces can be immediately captured on the filter membrane, and filter membrane samples are available right after cleaning, reducing the residence time of contaminants in cleaning fluid. It replaces conventional manual cleaning & testing methods, standardizes the cleanliness inspection workflow and greatly improves testing efficiency.

Custom tailor-made solutions can be provided to suit various workpiece sizes from different clients

The equipment integrates pressure jet cleaning, on-line filtration and recovery of cleaning agent, and circulating fine filtration. It enables synchronous component cleaning and filtration & recovery of particulate contaminants. Particulate contaminants on component surfaces can be captured onto the filter membrane in a timely manner. Filter membrane samples are readily available once component cleaning is completed, shortening the residence time of particulate contaminants in the cleaning agent. It transforms the traditional manual cleaning and testing approach, standardizes the cleanliness inspection control process, and improves the efficiency of cleanliness testing.

The independent operating space for component cleaning is equipped with a built-in laminar airflow system to purify the cleaning environment. An air curtain isolation system is installed on the operator side to effectively separate the cleaning zone from the external environment, building a clean operating platform for cleaning and inspection.

The working pressure of the equipment is displayed in real time. The cleaning and testing pressure is continuously adjustable. Matched with different cleaning nozzles, it can quickly and conveniently clean internal channels, blind holes and overall surfaces of components. It is widely applied to cleanliness testing of various automotive parts.

The equipment complies with international and domestic standards including ISO 16232:2007, VDA 19 and GB/T 3821-2005, and meets the cleanliness testing specifications of major automobile manufacturers such as Volkswagen, General Motors and Ford.

Laminar airflow purification

The equipment is equipped with an air supply unit featuring air circulation and filtration functions. The fan draws air from the top and passes it through HEPA filters. The filtered clean air is delivered uniformly at a wind speed of 0.45 m/s ±10%, ensuring stable and consistent laminar airflow. A Class 1000 or Class 100 clean space is formed within the cleaning working area (the cleanliness level of ordinary laboratories is Class 1,000,000), providing an ideal operating environment for component cleanliness testing and minimizing the impact of external surroundings on test results.

Automatic Ultrasonic Cleaning

Ultrasonic vibration cleaning utilizes cavitation, acceleration and direct flow effects of ultrasonic waves in liquid to exert direct and indirect impacts on liquid and contaminants. It generates pressure of 10¹²–10¹³ Pa and localized temperature rise around bubbles, breaking the adhesion of insoluble particulate contaminants so that they disperse into the solution, and ultimately removing particulate contaminants on component surfaces. It delivers better cleaning performance and superior uniformity compared with pressure jet cleaning. This function is integrated inside the equipment to enable fully automatic ultrasonic cleaning and raise the automation level of cleaning and testing processes.

Pressure jet cleaning

The pressure jet cleaning port inside the cleaning zone can be used to clean the testing areas of components according to preset parameters. A pressure cleaning gun can be operated manually to flush component surfaces in accordance with cleaning procedures. The cleaning pressure, flow rate and angle are adjustable as required by specifications.

On-line Filtration Sample Preparation

After cleaning components, the used cleaning agent flows through the on-line filter to realize synchronous automatic filtration and recovery. Particulate contaminants washed off from component surfaces in the cleaning fluid are timely captured on the test filter membrane. Manual filtration of cleaning fluid is no longer required.

Cleaning Agent Fine Filtration

The equipment adopts special cleaning fluid for cleanliness testing. The cleaning fluid acts as a carrier to extract particulate contaminants from components. The cleaning fluid itself must be free of contaminants that may interfere with test results. Integrated with an automatic fine filtration function for cleaning fluid, the unit ensures the cleaning fluid is clean prior to component cleaning. The cleanliness of the fluid can be verified via the terminal filtration device.

Add / Replace Cleaning Fluid

The maximum internal loading capacity of the equipment is 20 L. The supporting cleaning fluid can be automatically fed into the unit through the fluid filling port. Users can adjust the filling volume according to cleaning and testing requirements. When cleaning fluid replacement is needed, activate the corresponding control button to open the fluid drain port, and the equipment will automatically discharge the used cleaning fluid.

Working Status Indication

It displays real-time information including current working status, flow rate, total volume of cleaning fluid and cleaning mode. The operating status is monitored continuously. In case of faults, the equipment will stop automatically and trigger an alarm. The corresponding fault information will be shown on the screen with troubleshooting guidance provided.

Cleaning Parameter Setting

Cleaning pressure, flow rate parameters, cleaning duration and cleaning mode can be adjusted and saved in accordance with different cleanliness testing standards.

Auxiliary Lighting

Industrial explosion-proof LED auxiliary lighting, energy-saving, eco-friendly, safe and reliable, with IP67 protection rating.
