   三螺杆(gǎn)泵(SN三螺杆泵,sm三螺(luó)杆泵,spf三螺杆泵)選(xuan)型時，要盡可能詳(xiang)盡地了解泵的使(shi)用條件，除運行參(can)數，如流量、壓力須(xu)要弄清楚之外，輸(shū)送的介質的特性(xing)如介質的腐蝕性(xing)，含氣量含固溶物(wu)的比率及固體顆(kē)粒的💯大小以及介(jiè)質的工作溫度、粘(zhān)度、比重對泵内過(guò)流元件的腐蝕性(xìng)等和泵裝置的吸(xī)入💞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.

   用戶可(ke)以填寫附在本樣(yàng)本後的泵數據表(biǎo)，由廠家⭐負責選型(xing)，也可以根據樣本(běn)按以下步驟自行(hang)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(beng)的轉速：（SN 系列螺杆(gan)泵的極限轉速為(wei)＜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(xuan)擇以輸送介質的(de)粘度和泵的規格(gé)确定轉速範圍，一(yī)般輸送高粘度介(jiè)質時，螺杆泵應選(xuǎn)低轉速；若粘度低(di) ，相應選擇高轉速(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.

   對于大規格的螺(luó)杆泵（主杆外徑∮60mm 以(yi)上）For the large size of screw pump (more than 30 main stem diameter of 60 mm)

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

   若γ＞80°E 如粘膠液，轉速(sù)可選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(dui)于小規格的螺杆(gǎn)泵（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，n 選1450rpm 或970rpm的螺杆泵(beng). Gamma > 20 ° E, n selected 1450 RPM and 970 RPM of screw pump.

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

   2．由(you)于螺杆泵的轉速(sù)愈高摩擦功率愈(yù)高，螺杆泵的磨損(sun)越大，壽☎️命越短，如(rú)果輸送介質的潤(run)滑性較差，或含🌈有(you)微量雜🌈質，應選較(jiao)🌍低轉速，使泵保持(chi)較長的使用壽🔱命(ming)。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， 結構形(xíng)式的選擇The choice of the form of structure

   結構的(de)選擇可根據螺杆(gǎn)泵的運行環境和(hé)安裝環境，選擇合(hé)适的安裝形式并(bing)遵循以下的原則(ze)：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． 輸送潤滑性油類(lèi)，且溫度T＜80℃時，選擇内(nei)置軸承結構的螺(luo)杆泵。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

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

   3． 輸送流(liu)動性差，粘度高的(de)介質或對所輸送(sòng)介質進💁行☔加熱或(huò)保溫時，選雙層加(jia)熱泵體結構的螺(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． 輸送高溫介(jie)質時，應選擇耐高(gāo)溫的材料制成的(de)泵或局部🚶‍♀️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． 關于螺杆(gǎn)泵的吸入能力可(kě)查閱樣本。5. About the screw pump suction capacity can refer to the samples.

   第三， 螺(luo)杆泵材料組合的(de)選擇 見上表Third, the choice of the screw pump material combination See the table above

   第四(sì)， 螺杆泵的吸上能(néng)力Fourth, the screw pump suction on ability

   通過降低轉速(su)或加熱降低介質(zhi)黏度的方法，可達(dá)到高的🔞吸上性能(neng)，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，配套電(diàn)機的選配Fifth, motor selection

   螺杆泵(beng)的型号選定後，根(gen)據樣本數據，可查(cha)到泵的軸功率N，該(gai)軸功率再加上一(yi)定的功率儲備後(hou)，作為選配電機📞的(de)依據✂️，一♻️般電機功(gōng)率Nm 不小于泵軸功(gong)率N 乘以功率儲備(bei)系數K 所得的值即(ji)：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
