   三(sān)螺杆泵(sn三(sān)螺杆(gǎn)泵,sm三螺杆泵(bèng),spf三螺杆泵)選(xuǎn)型時(shí)，要盡可能詳盡(jìn)地了(le)解泵的使(shǐ)用(yòng)條件，除運行(háng)參數(shù)，如流量(liàng)、壓力須(xū)要弄(nòng)清楚(chǔ)之外，輸送的介質的(de)特(tè)性(xìng)如介(jiè)質的腐蝕(shí)性，含(hán)氣量(liàng)含固溶物(wù)的比率及(jí)固體(tǐ)顆粒的大小以(yǐ)及介質的(de)工作溫度、粘度、比重(zhòng)對泵内過流元(yuán)件的腐(fǔ)蝕性等(děng)和泵裝置的吸(xī)入條(tiáo)件(jiàn)，安裝條(tiáo)件均要(yào)了解。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(yòng)戶可以(yǐ)填寫附在本樣本(běn)後的泵數據表(biǎo)，由廠家負責選型，也可以(yǐ)根據樣本(běn)按以(yǐ)下(xià)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， 确定泵的轉速：（sn 系(xì)列螺(luó)杆泵的極(jí)限轉速(sù)為＜6000r.p.m）determine the speed of the pump: (sn series screw pump limit speed for < 6000 r. p.)

   1．螺杆泵轉速的選擇(zé)以輸送介(jiè)質的粘度(dù)和(hé)泵的規(guī)格确定轉(zhuǎn)速範(fàn)圍，一(yī)般輸送高(gāo)粘度介質時，螺(luó)杆泵(bèng)應選低轉速；若粘度低 ，相應選(xuǎn)擇高(gāo)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.

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

   介(jiè)質粘(zhān)度γ＞20°e 時，轉速以970rpm 或(huò)720rpm 的螺(luó)杆(gǎn)泵。medium viscosity gamma > 20 ° e, screw pump speed to 970 rpm and 720 rpm.

   若γ＞80°e 如粘膠液，轉速可(kě)選n=200~500rpm的螺杆(gǎn)泵if gamma > 80 ° e, such as viscose, of optional n = 200 ~ 500 rpm of the screw pump

   對(duì)于小規(guī)格的螺(luó)杆泵(bèng)（主杆外徑∮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)螺杆泵. gamma > 20 ° e, n selected 1450 rpm and 970 rpm of screw pump.

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

   2．由于螺(luó)杆泵的轉速愈高摩擦(cā)功率愈(yù)高，螺杆泵的磨(mó)損越(yuè)大，壽命越(yuè)短，如果輸送(sòng)介質的潤(rùn)滑性較(jiào)差，或含有(yǒu)微量雜質，應選(xuǎn)較低(dī)轉速，使(shǐ)泵(bèng)保持(chí)較長(zhǎng)的使用壽(shòu)命。推薦(jiàn)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.

   2． 輸(shū)送潤滑性較(jiào)差，或溫度t＞80℃時(shí)，選擇外置軸承結構的螺(luó)杆泵。2. the conveyor lubrication is poorer, or temperature t > 80 ℃, select external bearing structure of the screw pump.

   3． 輸送流動(dòng)性差，粘度(dù)高的(de)介質(zhì)或(huò)對所輸(shū)送介質進行(háng)加(jiā)熱或(huò)保溫時，選(xuǎn)雙層(céng)加熱泵(bèng)體(tǐ)結構(gòu)的螺(luó)杆泵。3. conveyor illiquid, high viscosity of the medium or the transport medium for heating or thermal insulation, choose double screw pump heat pump body structure.

   4． 輸送(sòng)高溫介質(zhì)時，應(yīng)選擇耐高溫的(de)材料制成(chéng)的泵(bèng)或局部冷卻的螺杆泵。4. high temperature medium, high temperature resistant materials should be selected for the pump or cooling screw pump.

   5． 關于螺(luó)杆(gǎn)泵的吸(xī)入能(néng)力可查閱樣本(běn)。5. about the screw pump suction capacity can refer to the samples.

   第五(wǔ)，配套電機(jī)的選(xuǎn)配fifth, motor selection

   螺(luó)杆泵(bèng)的型号(hào)選定後(hòu)，根據(jù)樣(yàng)本(běn)數據(jù)，可查(chá)到泵的軸(zhóu)功率(lǜ)n，該軸(zhóu)功率(lǜ)再加上(shàng)一定的功率儲備(bèi)後，作為選(xuǎn)配電機的(de)依(yī)據(jù)，一(yī)般電機(jī)功率(lǜ)nm 不小(xiǎo)于泵(bèng)軸功率(lǜ)n 乘(chéng)以功率儲備系(xì)數k 所(suǒ)得的值即：nm≥k·n。k 值screw pump model is selected, according to the sample data, the pump shaft power can be n, the shaft power plus the power of a certain reserve, as a basis for the matching machine, general motors power nm not less than the pump shaft power n times the power reserve coefficient k of the proceeds of the value, namely: the nm acuity k. n.k value
