Clean and upscale the engineering cross-section blueprint in the reference image. Preserve only the pure mechanical drawing: retain the original cross-sectional geometry, component contours, internal mechanical details, and technical drawing lines. Completely remove every text label, annotation, leader line, arrow, caption, lettering, and symbol, including labels such as “Корпус экспеллера,” “Импеллер,” and “Центробежное - металл.” Do not leave any text or symbols anywhere. Convert the result to strict binary black and white: a perfectly pure white background (#FFFFFF) and solid, smooth, high-contrast black drawing lines (#000000), with no gray tones, shading, gradients, or colored pixels. Remove digital noise and speckles, clean up broken or jagged strokes, smooth pixelated edges, and produce crisp, precise, consistent linework resembling a professional CAD/vector blueprint export. Keep the original drawing composition and mechanical proportions intact; do not invent or add components.
