ANALYSIS OF THE TENSIONING FORCE OF THE DRAINAGE MATERIAL DURING FABRICATION OF A ROLL TYPE REVERSE OSMOSIS MODULE

摘要

A procedure is proposed for determination of forces and stresses during winding of the drainage material during fabrication of a roll module from conditions of stability, strength, and stiffness of the discharge tube. The condition whereby there is no displacement of the wound layers of a roll module in the axial direction, which develop as a result of a difference in pressure at the ends of the modules (telescopic effect), is examined. winding, drainage material, discharge tube, tensile force, tensile stress, compressive stress, axial displacement, telescoping effect
