Refurbishment process of the pumping unit in a volumetric screw compressor of the "oil free' type |
| abstract |
A refurbishment process for a volumetric screw compressor of the ‘oil-free’ type, which comprises a male rotor and a female rotor, is described. The process comprises visually checking the wear condition of the rotors, treating their surface for removing the previous coating, and applying a new coating on the surface. The composition of the coating applied on the surface of the rotors consists of the following materials: n n n n n n n n n n n n Material n Amount (g) n n n n n n Polytetrafluoroethylene n 750 ÷ 850 n n n (954G 303 C Teflon, DuPont) n n n Amorphous graphite powder n 300 ÷ 400 n n n Thinner for spray cleaning apparatuses n 200 ÷ 270 n n n (8595 thinner, DuPont) n n n Methyl ethyl ketone (MEK) n 170 ÷ 220 n n n Cellosolve acetate coating additive n 200 ÷ 300 n n n (Syn Fac 800 resin) |
