   三(san)螺杆泵(beng)(SN三螺杆(gǎn)泵,sm三螺(luó)杆泵,spf三(san)螺杆泵(bèng))選型時(shi)，要盡可(kě)能詳盡(jin)地了解(jie)泵的使(shi)用條件(jiàn)，除運行(hang)參數，如(ru)流量、壓(ya)力須要(yào)弄清楚(chǔ)之外，輸(shu)送的介(jie)質的特(te)🔴性如介(jiè)質的腐(fǔ)蝕性，含(han)氣量含(han)固溶物(wu)的比率(lǜ)及固體(ti)顆粒的(de)大小以(yi)及介質(zhì)的工作(zuò)溫度、粘(zhān)度、比重(zhòng)對泵内(nèi)過流元(yuán)件的腐(fǔ)蝕性♋等(děng)和泵裝(zhuāng)置的吸(xi)入🎯條件(jiàn)，安裝條(tiao)件均要(yao)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(yǐ)填寫附(fù)在本樣(yàng)本後的(de)泵數據(ju)表，由廠(chang)家負責(zé)選型，也(yě)可以根(gēn)據樣本(běn)按以下(xià)步驟自(zì)行選型(xíng)。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(de)轉速：（SN 系(xi)列螺杆(gǎn)泵的極(jí)限轉速(sù)為＜6000r.p.m）Determine the speed of the pump: (SN series screw pump limit speed for < 6000 r. p.)

   1．螺杆(gan)泵轉速(sù)的選擇(ze)以輸送(song)介質的(de)粘度和(hé)泵的規(guī)格确定(dìng)轉速範(fàn)圍，一般(ban)輸送高(gāo)粘度介(jiè)質時，螺(luó)杆泵應(ying)選低轉(zhuan)速；若粘(zhan)度✉️低 ，相(xiàng)⛱️應選擇(ze)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(dà)規格的(de)螺杆泵(bèng)（主杆外(wai)徑∮60mm 以上(shang)）For the large size of screw pump (more than 30 main stem diameter of 60 mm)

   介質粘(zhan)度γ＞20°E 時，轉(zhuǎn)速以970rpm 或(huò)720rpm 的螺杆(gǎn)泵。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若γ＞80°E 如(rú)粘膠液(yè)，轉速可(ke)選n=200~500rpm的螺(luo)杆泵If gamma > 80 ° E, such as viscose, of optional n = 200 ~ 500 RPM of the screw pump

   對(duì)于小規(guī)格的螺(luo)杆泵（主(zhu)杆外徑(jing)∮60mm 以下）：For small specifications of the screw pump (below 30 main stem diameter of 60 mm) :

   γ＞20°E 時(shí)，n 選1450rpm 或970rpm的(de)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(de)螺杆泵(bèng)。Gamma > 80 ° E, n selected 300 ~ 600 RPM of the screw pump.

   2．由于螺(luó)杆泵的(de)轉速愈(yu)高摩擦(ca)功率愈(yù)高，螺杆(gǎn)泵的磨(mo)損越🈲大(dà)，壽命越(yuè)短，如果(guǒ)輸送介(jiè)質的潤(run)滑性較(jiào)差，或含(han)有微量(liang)雜質，應(yīng)選較低(di)轉速，使(shǐ)泵保持(chi)較長的(de)使用壽(shou)命。推薦(jian)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(jie)構形式(shì)的選擇(ze)The choice of the form of structure

   結構的(de)選擇可(ke)根據螺(luó)杆泵的(de)運行環(huan)境和安(an)裝環境(jìng)，選擇🔆合(hé)适的安(an)裝形式(shi)并遵循(xun)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:

   2． 輸送(sòng)潤滑性(xing)較差，或(huò)溫度T＞80℃時(shí)，選擇外(wai)置軸承(chéng)結構的(de)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(liu)動性差(cha)，粘度高(gao)的介質(zhì)或對所(suo)輸送介(jiè)質進行(hang)加🎯熱或(huò)保溫時(shi)，選雙層(céng)加熱泵(beng)體結構(gou)的螺杆(gan)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(song)高溫介(jiè)質時，應(yīng)選擇耐(nài)高溫的(de)材料制(zhi)成的泵(bèng)或局部(bu)冷卻的(de)螺杆泵(bèng)。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(de)吸入能(néng)力可查(chá)閱樣本(běn)。5. About the screw pump suction capacity can refer to the samples.

   第三， 螺(luó)杆泵材(cái)料組合(hé)的選擇(ze) 見上表(biǎo)Third, the choice of the screw pump material combination See the table above

   第五，配(pei)套電機(jī)的選配(pei)Fifth, motor selection

   螺杆泵(beng)的型号(hao)選定後(hòu)，根據樣(yàng)本數據(ju)，可查到(dao)泵的軸(zhou)功率N，該(gāi)軸功率(lǜ)再加上(shang)一定的(de)功率儲(chu)備後，作(zuò)為選配(pèi)電機的(de)依據，一(yi)般電機(jī)功率Nm 不(bú)小于泵(bèng)軸功率(lü)N 乘以功(gōng)率儲備(bèi)系數K 所(suǒ)得的值(zhi)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
