   第(dì)一， 确定(ding)泵的轉(zhuan)速：（SN 系列(lie)螺杆泵(beng)的極限(xiàn)轉速為(wei)＜6000r.p.m）Determine the speed of the pump: (SN series screw pump limit speed for < 6000 r. p.)

   1．螺杆泵(beng)轉速的(de)選擇以(yǐ)輸送介(jie)質的粘(zhan)度和泵(beng)的規格(ge)确定轉(zhuǎn)速範圍(wei)，一般輸(shū)送高粘(zhān)度介質(zhi)時，螺杆(gan)泵應選(xuǎn)低轉速(sù)；若粘度(dù)低 ，相應(ying)選擇高(gāo)轉速。The rotational speed of screw pump selection for medium viscosity and determine speed range of the specifications of the pump, transmission of high viscosity media in general, the screw pump should choose low speed;If the low viscosity, high speed accordingly.

   對(dui)于大規(guī)格的螺(luó)杆泵（主(zhu)杆外徑(jing)∮60mm 以上）For the large size of screw pump (more than 30 main stem diameter of 60 mm)

   介(jiè)質粘度(dù)γ＞20°E 時，轉速(sù)以970rpm 或720rpm 的(de)螺杆泵(beng)。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若γ＞80°E 如粘(zhān)膠液，轉(zhuan)速可選(xuan)n=200~500rpm的螺杆(gan)泵If gamma > 80 ° E, such as viscose, of optional n = 200 ~ 500 RPM of the screw pump

   對于(yú)小規格(ge)的螺杆(gan)泵（主杆(gan)外徑∮60mm 以(yǐ)下）：For small specifications of the screw pump (below 30 main stem diameter of 60 mm) :

   γ＞20°E 時，n 選(xuǎn)1450rpm 或970rpm的螺(luó)杆泵. Gamma > 20 ° E, n selected 1450 RPM and 970 RPM of screw pump.
