Patch Test Bench
Description
The cleanliness checking bench is primarily used to check the cleanliness
of finished components prior to shipment/usage at any stage of the manufacturing process.
It is intended to be used in a clean room environment
Fluid is passed through the component to collect any debris
present and flush it through. The debris is collected and
analysed to determine the cleanliness of the component.
Components of almost any shape may be checked using this
apparatus and the size is only limited by the internal
dimensions of the cabinet. The working area can be connected to
a factory air extraction system or the air can be re-circulated
through an integral carbon filter to prevent fumes escaping from
the cabinet.
Patch Test Bench
Operation
The component to be checked is loaded into the cabinet where connections are made to the inlet and the outlet. Pressurised fluid is passed through a 0.8 micron filter to ensure it is clean before being passed through the component. When the fluid exits the component it passes through a test patch, the underside of which has a negative pressure applied to it to draw the fluid through. When a specified amount of fluid has been passed through the component for a set time the flushing process is over. The patch is removed from the machine and analysed using external equipment to determine the cleanliness of the test component.
