   三(sān)螺杆泵(sn三螺杆(gǎn)泵,sm三螺(luó)杆泵,spf三(sān)螺杆泵)選(xuǎn)型時，要盡(jìn)可(kě)能(néng)詳盡地了解泵的使用條(tiáo)件，除運行(háng)參數(shù)，如流量、壓(yā)力須要弄(nòng)清楚之外(wài)，輸(shū)送的介質的(de)特性如介(jiè)質的(de)腐蝕(shí)性，含(hán)氣量含固溶物(wù)的比(bǐ)率(lǜ)及(jí)固體顆粒的(de)大小以(yǐ)及介質的(de)工作(zuò)溫度、粘度(dù)、比重(zhòng)對泵(bèng)内(nèi)過流(liú)元件的腐蝕性等(děng)和泵(bèng)裝置(zhì)的吸入條(tiáo)件，安(ān)裝條(tiáo)件均要了解。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(fù)在本(běn)樣本後的泵數(shù)據表(biǎo)，由廠家負責選型，也(yě)可以根據樣本(běn)按以下步(bù)驟自行選型。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(dì)一， 确定泵的(de)轉速：（sn 系列螺杆泵(bèng)的極限轉速為＜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(shū)送(sòng)介質的粘度(dù)和泵的規格确定轉速範(fàn)圍，一般輸送高(gāo)粘度(dù)介質時，螺(luó)杆泵(bèng)應(yīng)選低轉(zhuǎn)速；若粘度低 ，相應選(xuǎn)擇高轉速(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.

   對于大規格的(de)螺杆(gǎn)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(shí)，轉(zhuǎn)速(sù)以970rpm 或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)粘膠液，轉速可(kě)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)于小規格的螺杆泵（主杆(gǎn)外徑(jìng)∮60mm 以下）：for small specifications of the screw pump (below 30 main stem diameter of 60 mm) :

   γ＞20°e 時，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(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(zhuǎn)速愈(yù)高摩(mó)擦(cā)功率愈高，螺杆泵的磨(mó)損(sǔn)越(yuè)大，壽命越(yuè)短，如果輸送介(jiè)質的潤滑性較(jiào)差，或含有微量雜質(zhì)，應選較低(dī)轉速，使泵保持較長的使用壽(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． 輸送潤(rùn)滑性較差(chà)，或(huò)溫(wēn)度t＞80℃時(shí)，選擇(zé)外置軸承(chéng)結構的螺杆泵(bèng)。2. the conveyor lubrication is poorer, or temperature t > 80 ℃, select external bearing structure of the screw pump.

   3． 輸送流動性差(chà)，粘度(dù)高的介質(zhì)或對所輸送介(jiè)質進行加熱或(huò)保溫(wēn)時，選雙層(céng)加熱泵體結構(gòu)的螺杆泵(bèng)。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(wēn)介質(zhì)時，應(yīng)選擇(zé)耐(nài)高溫的材料(liào)制成的泵(bèng)或局部(bù)冷卻的(de)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)杆泵的吸(xī)入能(néng)力可(kě)查閱樣本(běn)。5. about the screw pump suction capacity can refer to the samples.

   第五(wǔ)，配套(tào)電機(jī)的選配fifth, motor selection

   螺(luó)杆泵(bèng)的型号選(xuǎn)定後(hòu)，根據(jù)樣本數據(jù)，可查到(dào)泵(bèng)的軸(zhóu)功率n，該(gāi)軸功率(lǜ)再加上一(yī)定的(de)功率儲備後，作為選配(pèi)電機的(de)依據，一(yī)般電機(jī)功率nm 不(bú)小于泵(bèng)軸功率n 乘以功(gōng)率儲備系數k 所(suǒ)得的(de)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
