   三(sān)螺杆泵(sn三螺杆泵,sm三(sān)螺杆泵,spf三(sān)螺杆泵)選型時，要盡(jìn)可能詳盡(jìn)地了解泵的使(shǐ)用條(tiáo)件，除(chú)運行(háng)參數，如流(liú)量、壓(yā)力須要(yào)弄清楚(chǔ)之外，輸(shū)送的介質的特(tè)性如介(jiè)質的腐蝕性(xìng)，含(hán)氣量(liàng)含固(gù)溶物(wù)的比率及固體(tǐ)顆粒的大小以(yǐ)及介質的(de)工作(zuò)溫度(dù)、粘度、比重(zhòng)對泵内過(guò)流元(yuán)件的腐蝕(shí)性等和泵裝置的吸(xī)入條件，安裝條(tiáo)件均(jun1)要了(le)解。three-screw pump (sn three screw pump, three screw pump, sm spf three screw pump selection, should understand the using condition of pump as much detail as possible, in addition to the operating parameters, such as flow rate, pressure need to figure out, transmission characteristics, such as corrosive medium, the medium of air content of solid solution and the ratio of the size of the solid particles as well as the working temperature, medium viscosity, specific gravity within the pump flow components of corrosive and pump suction conditions, such as the installation conditions are to understand.

   用戶可以填寫附(fù)在本(běn)樣(yàng)本後的(de)泵數(shù)據(jù)表，由廠(chǎng)家(jiā)負責選型，也可以根據樣(yàng)本(běn)按以(yǐ)下步驟自(zì)行選型。user can fill in the attached to this sample after pump data sheets, the manufacturer shall be responsible for the selection, can also according to the sample, follow these steps to selection.

   第一， 确(què)定泵(bèng)的轉速：（sn 系(xì)列(liè)螺杆泵的極(jí)限轉速為(wéi)＜6000r.p.m）determine the speed of the pump: (sn series screw pump limit speed for < 6000 r. p.)

   1．螺杆(gǎn)泵轉速的選擇(zé)以輸送介(jiè)質的(de)粘度和泵的規(guī)格确定轉速範(fàn)圍，一般(bān)輸送高(gāo)粘度介質(zhì)時，螺杆泵應選低轉(zhuǎn)速；若粘度(dù)低 ，相(xiàng)應選擇(zé)高轉速(sù)。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.

   對于大(dà)規格的(de)螺杆泵（主(zhǔ)杆外(wài)徑∮60mm 以上）for the large size of screw pump (more than 30 main stem diameter of 60 mm)

   介質粘(zhān)度γ＞20°e 時，轉速以970rpm 或(huò)720rpm 的螺杆泵。medium viscosity gamma > 20 ° e, screw pump speed to 970 rpm and 720 rpm.

   若γ＞80°e 如(rú)粘膠(jiāo)液，轉(zhuǎn)速可選n=200~500rpm的螺杆泵if gamma > 80 ° e, such as viscose, of optional n = 200 ~ 500 rpm of the screw pump

   對(duì)于小(xiǎo)規格(gé)的螺(luó)杆泵（主(zhǔ)杆(gǎn)外徑∮60mm 以下(xià)）：for small specifications of the screw pump (below 30 main stem diameter of 60 mm) :

   γ＞20°e 時(shí)，n 選1450rpm 或970rpm的(de)螺杆(gǎn)泵. gamma > 20 ° e, n selected 1450 rpm and 970 rpm of screw pump.

   γ＞80°e 時，n 選300~600rpm的螺杆(gǎn)泵。gamma > 80 ° e, n selected 300 ~ 600 rpm of the screw pump.

   2．由于螺(luó)杆泵的轉速愈(yù)高摩(mó)擦功率愈(yù)高，螺杆泵的磨(mó)損越大，壽命越短，如果(guǒ)輸(shū)送介(jiè)質的(de)潤(rùn)滑性較(jiào)差，或(huò)含有(yǒu)微量雜質(zhì)，應選(xuǎn)較低(dī)轉速，使泵保持較長的使(shǐ)用壽(shòu)命。推(tuī)薦n＜1450rpm。friction due to the higher the rotational speed of screw pump power, the higher the wear and tear of screw pump, the greater the shorter life, if the medium of lubricity is poorer, or trace impurities, should choose a lower speed, to keep pump with long service life.the recommended n < 1450 rpm.
