   三螺杆泵(bèng)(SN三螺杆泵,sm三螺杆泵,spf三(sān)螺杆泵)選型(xíng)時，要盡可能詳盡地了解泵的使(shǐ)用條件，除運行參數(shù)，如流量、壓力須要弄清楚之外，輸送(sòng)的介質的特性如介(jiè)質的腐蝕性，含(hán)氣量含固溶物的(de)比率及固體顆粒(lì)的大小以及介質的工作溫度(dù)、粘度(dù)、比重對泵内過流元件的(de)腐蝕性等(děng)和泵裝置的吸入條件，安裝條件均要了解。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.

   用戶可以(yǐ)填寫附(fù)在本樣本後的(de)泵數據表，由廠家負責(zé)選型，也可以根據(jù)樣本(běn)按以下步驟自行選型。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， 确(què)定泵的轉速：（SN 系(xì)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．螺杆泵轉速的選擇以輸(shū)送介質的粘度和泵的規(guī)格确定轉速範圍，一(yī)般輸(shū)送高粘度介質時，螺杆(gǎn)泵應選低轉速；若粘度低 ，相應選(xuǎn)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.

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

   介質粘度γ＞20°E 時，轉速以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 如粘膠液(yè)，轉速可選n=200~500rpm的螺杆泵If gamma > 80 ° E, such as viscose, of optional n = 200 ~ 500 RPM of the screw pump

   對于小規格的螺(luó)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(de)螺杆泵. Gamma > 20 ° E, n selected 1450 RPM and 970 RPM of screw pump.

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

   2．由于螺杆泵的轉(zhuǎn)速愈高摩擦功率愈(yù)高，螺杆(gǎn)泵的磨損越大，壽(shòu)命越短，如果輸送介質的潤滑性較差，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， 結構形式的選擇The choice of the form of structure

   結構的選(xuǎn)擇可根據螺杆(gǎn)泵的(de)運行環境和安裝環境，選擇合(hé)适的安裝形式(shì)并遵(zūn)循(xún)以下的原則：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(shū)送潤滑性油類，且溫度T＜80℃時(shí)，選擇内置軸承結構的螺杆泵。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

   2． 輸送潤滑性較(jiào)差(chà)，或溫度T＞80℃時，選擇(zé)外置軸承結構的螺杆泵(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，粘度(dù)高的介質或對所輸送介質進行加熱或保溫時，選雙層(céng)加熱泵體結構的螺杆泵。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． 輸送高溫介質時，應選擇耐高溫(wēn)的材料制成的泵或局部冷卻的(de)螺(luó)杆泵。4. High temperature medium, high temperature resistant materials should be selected for the pump or cooling screw pump.

   5． 關于螺杆泵(bèng)的吸入能力可查(chá)閱樣本。5. About the screw pump suction capacity can refer to the samples.

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

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

   通過降低轉速或加熱降低介質黏度的方法，可(kě)達到(dào)高的吸上性能，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，配套電機(jī)的選配Fifth, motor selection

   螺杆泵的型号選定後，根據樣本(běn)數據(jù)，可查到(dào)泵的軸功率N，該軸功率再加(jiā)上一定的功率儲備後，作為選配電機的(de)依據，一般電機功(gōng)率Nm 不小于泵軸功率N 乘以功率儲備系數K 所(suǒ)得的值即：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
