| 螺杆泵的材料有哪些 What are the screw material 螺杆泵转子由于工况恶劣，因此选材比空压机、制冷机的螺杆要好，如选用38CrMoAl、40Cr、20Cr13、16Mn、CrS5的、常需经渗氮硬化（HRc56-65）。也有选用CrNi、CrMo、CrNiMo不锈钢、MnCrS钢等 Screw pump rotor due to poor working conditions, so selection than the air compressor, screw chiller is better, such as the selection of 38CrMoAl, 40Cr, 20Cr13, 16Mn, CrS5, and often subject to nitriding, hardening (HRc56-65). Have also selected CrNi, CrMo, CrNiMo stainless steel, MnCrS steel |
