   三螺杆(gan)泵(SN三螺杆泵,sm三(san)螺杆泵,spf三螺杆(gǎn)泵)選型時，要盡(jin)可能詳盡地了(le)解泵的使用條(tiáo)件，除運行參數(shù)，如流量、壓力須(xū)要弄清楚之外(wai)，輸送的介質的(de)特性如介質的(de)腐蝕性，含氣量(liang)含固溶物的比(bǐ)率及固體顆粒(li)的大小以及介(jie)質🔱的工作溫度(dù)、粘度、比重對泵(beng)内過流元件的(de)腐蝕性✂️等和泵(bèng)裝置的吸入☁️條(tiáo)件，安裝條件均(jun)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(kě)以填寫附在本(ben)樣本後的泵數(shù)據表，由廠家負(fù)責選型，也可以(yi)根據樣本按以(yǐ)下步驟自行選(xuǎn)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(bèng)的轉速：（SN 系列螺(luo)杆泵的極限轉(zhuǎn)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(zhuan)速的選擇以輸(shū)送介質的粘度(du)和泵的規格确(que)定🈲轉速範圍，一(yi)般輸送高粘度(dù)介質時，螺杆泵(bèng)應選📐低轉速；若(ruò)🔴粘度低 ，相㊙️應選(xuǎn)擇高轉速。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(yú)大規格的螺杆(gǎn)泵（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γ＞20°E 時(shí)，轉速以970rpm 或720rpm 的螺(luo)杆泵。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若γ＞80°E 如粘膠(jiāo)液，轉速可選n=200~500rpm的(de)螺杆泵If gamma > 80 ° E, such as viscose, of optional n = 200 ~ 500 RPM of the screw pump

   對于小(xiǎo)規格的螺杆泵(beng)（主杆外徑∮60mm 以下(xia)）：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(gan)泵. Gamma > 20 ° E, n selected 1450 RPM and 970 RPM of screw pump.

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

   2．由于螺杆泵(beng)的轉速愈高摩(mó)擦功率愈高，螺(luó)杆泵的♌磨損越(yuè)大，壽命越短，如(ru)果輸送介質的(de)潤滑性較差♈，或(huò)含有微量雜質(zhi)，應選較低轉速(sù)，使泵保持較長(zhang)的❗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， 結構形(xíng)式的選擇The choice of the form of structure

   結構(gòu)的選擇可根據(ju)螺杆泵的運行(háng)環境和安裝環(huán)境，選擇合💋适的(de)安裝形式并遵(zūn)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(yóu)類，且溫度T＜80℃時，選(xuǎn)擇内置軸承結(jie)構的螺杆泵。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

   2． 輸(shu)送潤滑性較差(chà)，或溫度T＞80℃時，選擇(ze)外置軸承結構(gou)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(sòng)流動性差，粘度(du)高的介質或對(dui)所輸送介質進(jin)行加💛熱或保溫(wen)時，選雙層加熱(re)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(wēn)介質時，應選擇(ze)耐高溫的材料(liao)制成的泵或🏃🏻‍♂️局(ju)部♍冷🔆卻的螺杆(gan)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(ke)查閱樣本。5. About the screw pump suction capacity can refer to the samples.

   第三(san)， 螺杆泵材料組(zu)合的選擇 見上(shàng)表Third, the choice of the screw pump material combination See the table above

   第四， 螺杆泵(beng)的吸上能力Fourth, the screw pump suction on ability

   通(tōng)過降低轉速或(huo)加熱降低介質(zhi)黏度的方法，可(kě)達到高的吸上(shàng)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(wǔ)，配套電機的選(xuan)配Fifth, motor selection

   螺杆泵的型(xing)号選定後，根據(jù)樣本數據，可查(chá)到泵的軸功率(lü)N，該軸功率再加(jiā)上一定的功率(lü)儲備後，作為選(xuan)配電機的依據(jù)，一般電機功率(lü)Nm 不小于泵軸功(gong)率N 乘以功率儲(chǔ)備系數K 所得的(de)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
