   三(sān)螺杆泵(SN三螺杆(gǎn)泵,sm三螺杆泵,spf三(san)螺杆泵)選型時(shi)，要盡可能詳盡(jin)地了解泵的使(shǐ)用條件，除運行(hang)💁參🔞數，如流量、壓(ya)力須要弄清楚(chu)之外，輸送的介(jie)質的特性如介(jie)質的腐蝕性📐，含(han)氣量含固溶物(wù)的比率及固體(tǐ)顆粒的💃大小以(yǐ)及介質的工作(zuo)溫度、粘度、比重(zhòng)對泵内過流元(yuán)件的腐蝕性等(deng)和泵裝置的吸(xi)入條件，安裝條(tiáo)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(yòng)戶可以填寫附(fu)在本樣本後的(de)泵數據表，由廠(chǎng)家負責選型⭐，也(ye)☂️可以根據樣本(běn)按以下步驟自(zi)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(xi)列螺杆泵的極(jí)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(gǎn)泵轉速的選擇(zé)以輸送介質的(de)粘度和泵的規(guī)格确定⭐轉⭐速範(fan)圍，一般輸送高(gāo)粘度介質時，螺(luó)杆泵應選🤩低轉(zhuǎn)速；若粘度低 ，相(xiang)應選擇高轉速(su)。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(de)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(zhān)度γ＞20°E 時，轉速以970rpm 或(huo)720rpm 的螺杆泵。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若γ＞80°E 如(ru)粘膠液，轉速可(ke)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(duì)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，n 選300~600rpm的(de)螺杆泵。Gamma > 80 ° E, n selected 300 ~ 600 RPM of the screw pump.

   2．由于螺(luó)杆泵的轉速愈(yu)高摩擦功率愈(yù)高，螺杆泵的磨(mó)損越大，壽命越(yue)短，如果輸送介(jie)質的潤滑性較(jiào)差，或含有微量(liàng)雜質，應選較低(dī)轉速，使泵保持(chí)較長的使用壽(shou)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(zé)The choice of the form of structure

   結構的選擇可(ke)根據螺杆泵的(de)運行環境和安(an)裝環🏃‍♂️境，選擇合(hé)适🈲的安裝形式(shì)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(huá)性油類，且溫度(dù)T＜80℃時，選擇内置軸(zhóu)承結構的螺杆(gǎn)泵。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

   2． 輸送潤滑性(xìng)較差，或溫度T＞80℃時(shí)，選擇外置軸承(chéng)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(chà)，粘度高的介質(zhi)或對所輸送介(jiè)質進行加熱或(huò)保溫時，選雙層(céng)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(sòng)高溫介質時，應(ying)選擇耐高溫的(de)材料制成的泵(beng)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(luó)杆泵的吸入能(néng)力可查閱樣本(běn)。5. About the screw pump suction capacity can refer to the samples.

   第三， 螺杆泵材(cái)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(luo)杆泵的吸上能(néng)力Fourth, the screw pump suction on ability

   通過降低轉(zhuan)速或加熱降低(di)介質黏度的方(fāng)法，可達🐇到高㊙️的(de)吸💃上🔴性能，見NPSHR 表(biǎo)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(bèng)的型号選定後(hou)，根據樣本數據(jù)，可查到泵的軸(zhóu)功率N，該軸功率(lǜ)再加上一定的(de)功率儲備後，作(zuò)為選配電機的(de)依據⛱️，一般電機(jī)功率Nm 不小于泵(beng)軸功率N 乘以功(gong)率儲備系數K 所(suo)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
