Low pressure injection module and method for low pressure injection cleaning with residual dirt analysis of components

A low-pressure spray module for spray cleaning a component, comprising:

• a receiver tank for holding a flushing medium, wherein an inlet side of the receiver tank is pressurized using compressed air from a compressed air source;
• a spray lance for pressurized spraying of the component using the flushing medium, wherein the spray lance is connected to an outlet side of the receiver tank;
• a collection tank positioned for collecting contaminant-particles-containing flushing medium after the pressurized spraying of the component;
• and
• an analysis filter coupled to an outflow side of the collection tank, wherein the contaminant-particles-containing flushing medium is extracted from the collection tank through the outflow side using a vacuum pump, whereby the analysis filter performs filtering of contaminant particles from the contaminant-particles-containing flushing medium, and wherein the analysis filter collects the contaminant particles for later analysis.

A method for low-pressure spray cleaning and residual contaminant analysis of a component, comprising:

• a) providing a receiver tank filled with a flushing medium;
• b) pressurizing the receiver tank on an inlet side using compressed air from a compressed air source;
• c) transmitting the flushing medium from the pressurized receiver tank to a spray lance;
• d) spray cleaning the component by spraying the flushing medium from the spray lance;
• e) collecting contaminant-particles-containing flushing medium in a collection tank after the spray cleaning;
• f) providing an analysis filter positioned on an outflow side of the collection tank, whereby the contaminant-particles-containing flushing medium flows through the analysis filter, wherein contaminant particles are filtered out of the contaminant-particles-containing flushing medium by the analysis filter;
• and
• g) analyzing the contaminant particles filtered out by the analysis filter.
