   三螺杆泵(SN三(sān)螺杆泵,sm三螺(luo)杆泵,spf三螺杆(gǎn)泵)選型時，要(yào)盡可能詳盡(jin)地了解泵的(de)使用條件，除(chú)運💃🏻行參☎️數，如(rú)流量、壓力須(xu)要弄清楚之(zhī)外，輸送的介(jie)質的特🙇‍♀️性如(rú)介質的腐☀️蝕(shi)性，含氣量含(han)固溶物的比(bi)率及固體顆(ke)粒的大小以(yǐ)😍及介質的工(gong)作溫度、粘度(dù)、比重對泵内(nei)🏃‍♂️過流元件的(de)腐蝕性等和(he)泵裝置的吸(xī)入🙇🏻條件，安裝(zhuang)條件均要了(le)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)填寫附在本(běn)樣本後的泵(bèng)數據表，由廠(chǎng)家負責🐕選型(xing)，也可以根據(jù)樣本按以下(xia)步驟自行選(xuan)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(ding)泵的轉速：（SN 系(xì)列螺杆泵的(de)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(su)的選擇以輸(shu)送介質的粘(zhān)度和泵的規(guī)格确定💘轉速(su)範圍，一般輸(shu)送高粘度介(jiè)質時，螺杆泵(beng)應選低轉速(sù)；若粘度低 ，相(xiang)應選擇高轉(zhuǎn)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(guī)格的螺杆泵(beng)（主杆外徑∮60mm 以(yǐ)上）For the large size of screw pump (more than 30 main stem diameter of 60 mm)

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

   若(ruò)γ＞80°E 如粘膠液，轉(zhuan)速可選n=200~500rpm的螺(luó)杆泵If gamma > 80 ° E, such as viscose, of optional n = 200 ~ 500 RPM of the screw pump

   對于小(xiǎo)規格的螺杆(gǎn)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(huò)970rpm的螺杆泵. Gamma > 20 ° E, n selected 1450 RPM and 970 RPM of screw pump.

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

   2．由于螺杆泵(bèng)的轉速愈高(gāo)摩擦功率愈(yu)高，螺杆泵的(de)磨🔞損越大，壽(shou)命越短，如果(guǒ)輸送介質的(de)潤滑性較差(chà)，或含㊙️有微🧡量(liàng)雜質，應選較(jiào)低轉速，使泵(bèng)保持較長的(de)♻️使用壽命。推(tuī)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(gòu)形式的選擇(ze)The choice of the form of structure

   結構的選擇(zé)可根據螺杆(gǎn)泵的運行環(huán)境和安裝環(huan)境⭐，選擇🌈合适(shì)的安裝形式(shì)并遵循以下(xià)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． 輸送(song)潤滑性油類(lei)，且溫度T＜80℃時，選(xuǎn)擇内置軸承(chéng)結構的螺杆(gan)泵。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

   2． 輸送潤滑(huá)性較差，或溫(wen)度T＞80℃時，選擇外(wài)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(shū)送流動性差(chà)，粘度高的介(jiè)質或對所輸(shu)送介質進行(háng)加熱或保🈲溫(wen)時，選雙層加(jiā)熱泵體結構(gòu)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(shū)送高溫介質(zhì)時，應選擇耐(nài)高溫的材料(liao)制成的泵或(huò)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(yú)螺杆泵的吸(xi)入能力可查(cha)閱樣本。5. About the screw pump suction capacity can refer to the samples.

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

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

   通過(guò)降低轉速或(huò)加熱降低介(jiè)質黏度的方(fāng)法，可達到高(gao)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(pei)套電機的選(xuǎn)配Fifth, motor selection

   螺杆泵的(de)型号選定後(hòu)，根據樣本數(shu)據，可查到泵(bèng)的☀️軸功率N，該(gai)軸功率再加(jiā)上一定的功(gong)率儲備後，作(zuo)為選配電機(ji)的依🤟據，一✏️般(ban)電機功率Nm 不(bu)小于泵軸功(gong)率N 乘以功率(lü)儲備系數K 所(suo)得的值即：Nm≥K·N。K 值(zhí)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
