DEVICE FOR ESTIMATING QUALITY AND RELIABILITY OF SURFACE COVERS OF INDUSTRIAL PRODUCTS Russian patent published in 2007 - IPC G01N19/00 G01N17/00 

FIELD: tool-making industry.

SUBSTANCE: device contains tank and squeeze reservoir-drum, mounted with possible rotation around a vertical axis, included in composition of internal moving part of laundry washer, four stretching supports with damping elements, which are oriented in space vertically and jointly connected to body and internal moving part of laundry washer. Lower end of stretching supports is connected to internal moving part of laundry washer above its gravity center so that tank may be positioned along four directions at similar distance from body wall and also so that tank may contact body wall due to unbalance mass during spin-up of squeeze reservoir-drum. On the wall of squeeze reservoir-drum, at height appropriate for position of gravity center of internal moving part of laundry washer, two apertures are made with possible positioning of wire for unbalance mass loads in them. Mounted at aforementioned height in squeeze reservoir-drum is balancing ring with chute for placement of samples being tested in form of metallic or glass balls of same diameter, quality and technology of cover production of which match industrial ones. Balls are interconnected by metallic thread to ensure their free movement in limited circular sector.

EFFECT: correct selection of valid products during quality control based on surface quality criterions.
