ما هو تأثير المنحنيات فى خط النيوماتيك
لكى نكون على دراية عند اختيار الكوع المناسب بين V.line/H.line
خط النقل العمودى V.line = vertical conveying line
خط النقل الافقى H.line = horizontal conveying line

That’s true for “straight” Elbows “bend” the direction of the particles. These bends cause particles to hit the inner wall of the elbow. Depending on the particles properties, elbow design, and air velocities, some particles get deflected to other areas of the elbow and some get deflected back to the air stream. Most slide against the elbow wall . This sliding generates frictional heat. Particles with low melting points, soften and smear along the wall, much like a crayon smears color on a bedroom wall. Smearing can happen fast, and once started, it often grows as incoming particles rub against the existing smear.
