   三螺杆泵(SN三螺杆(gan)泵,sm三螺杆泵,spf三螺(luo)杆泵)選型時，要盡(jìn)可能詳盡地了解(jiě)泵的使用條件，除(chu)運行🏃🏻‍♂️參數💰，如流量(liàng)、壓力須要弄清楚(chu)之外，輸送的介質(zhì)的特性如🔞介質的(de)腐📞蝕性🚶‍♀️，含氣量含(han)固溶物的比率及(jí)固體顆粒的大小(xiǎo)以及介質的工作(zuo)溫度、粘度、比重對(duì)泵内過流元件的(de)腐蝕性等和泵裝(zhuang)置的吸入✍️條件，安(an)裝條♌件均要了解(jiě)。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(fu)在本樣本後的泵(beng)數據表，由廠家負(fu)責選型，也可以根(gēn)據樣本按以下步(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.

   第一(yī)， 确定泵的轉速：（SN 系(xi)列螺杆泵的極限(xiàn)轉速為＜6000r.p.m）Determine the speed of the pump: (SN series screw pump limit speed for < 6000 r. p.)

   1．螺杆泵轉(zhuan)速的選擇以輸送(song)介質的粘度和泵(beng)的規格确定轉速(sù)範圍，一般輸送高(gao)粘度介質時，螺杆(gan)泵應選低轉🧑🏾‍🤝‍🧑🏼速；若(ruo)粘度低 ，相應選擇(zé)高轉速。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.

   對于大規(gui)格的螺杆泵（主杆(gǎn)外徑∮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720rpm 的(de)螺杆泵。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若γ＞80°E 如粘膠(jiao)液，轉速可選n=200~500rpm的螺(luo)杆泵If gamma > 80 ° E, such as viscose, of optional n = 200 ~ 500 RPM of the screw pump

   對于小規格(ge)的螺杆泵（主杆外(wài)徑∮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)螺杆泵. Gamma > 20 ° E, n selected 1450 RPM and 970 RPM of screw pump.

   γ＞80°E 時，n 選300~600rpm的螺(luo)杆泵。Gamma > 80 ° E, n selected 300 ~ 600 RPM of the screw pump.

   2．由于螺杆泵(bèng)的轉速愈高摩擦(ca)功率愈高，螺杆泵(bèng)的磨損越💔大，壽命(mìng)越短，如果輸送介(jiè)質的潤滑性較差(chà)，或含💁有微量雜質(zhì)，應選較低轉速，使(shǐ)泵保持較長的使(shi)用壽命。推薦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.

   第二(er)， 結構形式的選擇(zé)The choice of the form of structure

   結構的選擇可根(gen)據螺杆泵的運行(háng)環境和安裝環境(jìng)，選擇🤩合适的安裝(zhuāng)形式并遵循以下(xia)的原則：On the choice of structure based on the operating conditions of a screw pump and the installation environment, choosing the appropriate type of installation and follow the following principles:

   1． 輸送潤滑(hua)性油類，且溫度T＜80℃時(shi)，選擇内置軸承結(jie)構的螺杆泵。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

   2． 輸送(sòng)潤滑性較差，或溫(wen)度T＞80℃時，選擇外置軸(zhou)承結構的螺杆泵(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，粘(zhān)度高的介質或對(duì)所輸送介質進行(háng)加熱或保溫時，選(xuǎn)雙層加熱泵體結(jie)構的螺杆泵。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)高溫介質時，應選(xuǎn)擇耐高溫的材料(liao)制成的泵或局部(bù)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(guān)于螺杆泵的吸入(rù)能力可查閱樣本(ben)。5. About the screw pump suction capacity can refer to the samples.

   第三， 螺杆泵材料(liao)組合的選擇 見上(shàng)表Third, the choice of the screw pump material combination See the table above

   第四， 螺杆泵的(de)吸上能力Fourth, the screw pump suction on ability

   通過降(jiàng)低轉速或加熱降(jiàng)低介質黏度的方(fang)法，可達到高🚶的吸(xi)上性能，見NPSHR 表By reducing the speed or heating medium viscosity reduction methods, can achieve high on absorption performance, see the NPSHR table

   第五(wu)，配套電機的選配(pei)Fifth, motor selection

   螺杆泵的型号選(xuǎn)定後，根據樣本數(shu)據，可查到泵的軸(zhóu)功率N，該軸功率再(zài)加上一定的功率(lǜ)儲備後，作為選配(pei)電機👨‍❤️‍👨的依據🍓，一✌️般(bān)電機功率Nm 不小于(yu)泵軸功率N 乘以功(gōng)率儲備系數K 所得(dé)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
