   三(san)螺杆泵(SN三螺杆泵(bèng),sm三螺杆泵,spf三螺杆(gan)泵)選型時，要盡可(ke)能詳盡地了解泵(bèng)的使用條件，除運(yùn)行參數，如流♌量、壓(yā)力須要弄清楚之(zhi)外，輸送的介質的(de)特性如介質的腐(fǔ)蝕性，含氣量含固(gù)溶物的比率及固(gù)體顆粒的大小以(yǐ)及介質的工作溫(wen)度、粘度、比重對泵(bèng)内過流元件😄的腐(fǔ)蝕性等和泵裝置(zhi)的吸入🤟條件，安裝(zhuāng)條件均要了解。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(yong)戶可以填寫附在(zài)本樣本後的泵數(shu)據表，由廠家負責(zé)選型，也可以根據(jù)樣本按以下步驟(zhou)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， 确(que)定泵的轉速：（SN 系列(liè)螺杆泵的極限轉(zhuǎn)速為＜6000r.p.m）Determine the speed of the pump: (SN series screw pump limit speed for < 6000 r. p.)

   1．螺杆泵轉速(sù)的選擇以輸送介(jiè)質的粘度和泵的(de)規格确🙇🏻定轉速範(fàn)圍，一般輸送高粘(zhan)度介質時，螺杆泵(beng)應選低轉👨‍❤️‍👨速；若粘(zhan)度低 ，相應選擇高(gāo)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.

   對于大規格(ge)的螺杆泵（主杆外(wai)徑∮60mm 以上）For the large size of screw pump (more than 30 main stem diameter of 60 mm)

   介質粘度(du)γ＞20°E 時，轉速以970rpm 或720rpm 的螺(luo)杆泵。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若γ＞80°E 如粘膠液(ye)，轉速可選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

   對于小規格的(de)螺杆泵（主杆外徑(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的螺杆(gan)泵。Gamma > 80 ° E, n selected 300 ~ 600 RPM of the screw pump.

   2．由于螺杆泵的(de)轉速愈高摩擦功(gong)率愈高，螺杆泵的(de)🈚磨🔴損🔴越大，壽🔞命越(yue)短，如果輸送介質(zhì)的潤滑性較差，或(huo)含有微量雜質，應(ying)選較低轉速，使泵(beng)保持較長的使用(yong)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， 結(jié)構形式的選擇The choice of the form of structure

   結(jié)構的選擇可根據(jù)螺杆泵的運行環(huán)境和安裝環境，選(xuǎn)擇合适✊的安裝形(xíng)式并遵循以下的(de)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． 輸送潤滑性(xing)油類，且溫度T＜80℃時，選(xuǎn)擇内置軸承結構(gou)的螺杆泵。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

   2． 輸送潤(rùn)滑性較差，或溫度(dù)T＞80℃時，選擇外置軸承(chéng)結構的螺杆泵。2. The conveyor lubrication is poorer, or temperature T > 80 ℃, select external bearing structure of the screw pump.

   3． 輸(shū)送流動性差，粘度(dù)高的介質或對所(suo)輸送介質進行加(jiā)熱或保溫時，選雙(shuang)層加熱泵體結構(gou)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． 輸送高(gao)溫介質時，應選擇(zé)耐高溫的材料制(zhì)成的泵或局部冷(leng)☁️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(yú)螺杆泵的吸入能(neng)力可查閱樣本。5. About the screw pump suction capacity can refer to the samples.

   第(di)三， 螺杆泵材料組(zǔ)合的選擇 見上表(biao)Third, the choice of the screw pump material combination See the table above

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

   通過降低(dī)轉速或加熱降低(di)介質黏度的方法(fǎ)，可達到高的吸上(shàng)‼️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，配(pei)套電機的選配Fifth, motor selection

   螺(luo)杆泵的型号選定(dìng)後，根據樣本數據(jù)，可查到泵的軸功(gong)率N，該軸功率再加(jia)上一定的功率儲(chǔ)備後，作為選配電(dian)機的🏃‍♀️依據，一般電(dian)機功率Nm 不小于泵(bèng)軸功率N 乘以功率(lǜ)儲備系數K 所得的(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
