   三螺(luo)杆泵(SN三螺杆泵(beng),sm三螺杆泵,spf三螺(luó)杆泵)選型時，要(yào)盡可能詳盡地(di)了解泵的使用(yong)條件，除運行參(can)數，如流量、壓力(li)須要弄清楚之(zhi)外，輸送的介質(zhì)✂️的特性如介質(zhi)的腐蝕性，含氣(qi)量含固溶物的(de)比率及固體顆(ke)粒的大小以😍及(jí)介質的工作溫(wēn)度、粘度、比重對(duì)泵内過流元件(jiàn)🔞的腐蝕性等和(he)泵裝置的吸入(ru)💚條件，安裝條件(jian)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.

   用戶(hù)可以填寫附在(zài)本樣本後的泵(beng)數據表，由廠家(jiā)負💃責選型，也可(kě)以根據樣本按(àn)以下步驟自行(háng)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(dìng)泵的轉速：（SN 系列(liè)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(bèng)轉速的選擇以(yǐ)輸送介質的粘(zhan)度和泵的規格(ge)❤️确定轉速範圍(wei)，一般輸送高粘(zhan)度介質時，螺杆(gan)泵應選低轉速(su)；若粘度低 ，相應(ying)選擇高轉速。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(duì)于大規格的螺(luó)杆泵（主杆外徑(jìng)∮60mm 以上）For the large size of screw pump (more than 30 main stem diameter of 60 mm)

   介質粘度(dù)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(zhan)膠液，轉速可選(xuǎn)n=200~500rpm的螺杆泵If gamma > 80 ° E, such as viscose, of optional n = 200 ~ 500 RPM of the screw pump

   對于(yú)小規格的螺杆(gǎn)泵（主杆外徑∮60mm 以(yi)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的螺(luó)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(gǎn)泵的轉速愈高(gāo)摩擦功率愈高(gao)，螺杆泵的磨損(sun)越大，壽命越短(duǎn)，如果輸送介質(zhi)的潤滑性較差(cha)‼️，或含有微💋量雜(za)質，應選較低轉(zhuǎn)速，使泵保持較(jiao)長的🔱使用壽命(mìng)。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， 結構(gòu)形式的選擇The choice of the form of structure

   結(jié)構的選擇可根(gen)據螺杆泵的運(yùn)行環境和安裝(zhuang)環境，選擇合适(shì)🆚的安裝形式并(bìng)遵循以下的原(yuán)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． 輸送潤滑性(xing)油類，且溫度T＜80℃時(shi)，選擇内置軸承(chéng)結構的螺杆泵(beng)。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

   2． 輸送潤滑性較(jiao)差，或溫度T＞80℃時，選(xuǎn)擇外置軸承結(jié)構的螺杆泵。2. The conveyor lubrication is poorer, or temperature T > 80 ℃, select external bearing structure of the screw pump.

   3． 輸(shu)送流動性差，粘(zhān)度高的介質或(huò)對所輸送介質(zhì)進行加🈲熱或㊙️保(bao)溫時，選雙層加(jia)熱泵體結構的(de)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． 輸送高(gao)溫介質時，應選(xuǎn)擇耐高溫的材(cai)料制成的泵或(huò)局部冷卻的螺(luó)杆泵。4. High temperature medium, high temperature resistant materials should be selected for the pump or cooling screw pump.

   5． 關于螺杆(gǎn)泵的吸入能力(lì)可查閱樣本。5. About the screw pump suction capacity can refer to the samples.

   第(di)三， 螺杆泵材料(liao)組合的選擇 見(jiàn)上表Third, the choice of the screw pump material combination See the table above

   第四， 螺杆(gan)泵的吸上能力(lì)Fourth, the screw pump suction on ability

   通過降低轉速(su)或加熱降低介(jiè)質黏度的方法(fǎ)，可達到🌏高的吸(xī)🛀🏻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(di)五，配套電機的(de)選配Fifth, motor selection

   螺杆泵的(de)型号選定後，根(gēn)據樣本數據，可(kě)查到泵的軸功(gong)率N，該軸功率再(zài)加上一定的功(gōng)率儲備後，作為(wéi)選配電機的依(yi)據，一般電機功(gong)率Nm 不小于泵軸(zhóu)功率N 乘以功率(lǜ)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
