   三螺杆(gǎn)泵(SN三螺杆泵(bèng),sm三螺杆泵,spf三(san)螺杆泵)選型(xing)時，要盡可能(néng)詳盡地了解(jie)泵的使用條(tiáo)件，除運行♉參(can)數，如流量、壓(ya)力須要弄清(qing)楚之外，輸送(song)的介質的特(tè)性如介質的(de)腐蝕性，含氣(qì)量含固溶物(wu)的比率及固(gu)體顆粒的🐉大(da)小以及介質(zhì)🐆的工作溫度(dù)、粘度、比重對(duì)泵内過流元(yuán)件的腐蝕性(xìng)等和泵裝置(zhi)的吸入條件(jiàn)，安裝條件均(jun1)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(hù)可以填寫附(fù)在本樣本後(hòu)的泵數據表(biao)，由廠家負責(ze)選型，也可以(yǐ)根據樣本按(àn)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(yī)， 确定泵的轉(zhuan)速：（SN 系列螺杆(gan)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(beng)轉速的選擇(zé)以輸送介質(zhi)的粘度和泵(beng)的規格确定(dìng)🔆轉速範圍，一(yi)般輸送高粘(zhan)度介質時，螺(luó)杆泵應選低(dī)轉速；若🔞粘度(du)低 ，相應選擇(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(yu)大規格的螺(luó)杆泵（主杆外(wài)徑∮60mm 以上）For the large size of screw pump (more than 30 main stem diameter of 60 mm)

   介質(zhì)粘度γ＞20°E 時，轉速(su)以970rpm 或720rpm 的螺杆(gǎn)泵。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若γ＞80°E 如粘膠(jiao)液，轉速可選(xuan)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(dui)于小規格的(de)螺杆泵（主杆(gǎn)外徑∮60mm 以下）：For small specifications of the screw pump (below 30 main stem diameter of 60 mm) :

   γ＞20°E 時(shi)，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(luó)杆泵。Gamma > 80 ° E, n selected 300 ~ 600 RPM of the screw pump.

   2．由于螺(luó)杆泵的轉速(su)愈高摩擦功(gōng)率愈高，螺杆(gǎn)泵的🈲磨損越(yuè)大，壽命越短(duan)，如果輸送介(jie)質的潤滑性(xìng)較差🌈，或含有(yǒu)微量雜質，應(yīng)選較低轉速(sù)，使泵保持較(jiào)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(èr)， 結構形式的(de)選擇The choice of the form of structure

   結構的(de)選擇可根據(jù)螺杆泵的運(yun)行環境和安(an)裝環境☀️，選擇(ze)合适的安裝(zhuang)形式并遵循(xun)以下的原則(zé)：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(xìng)油類，且溫度(dù)T＜80℃時，選擇内置(zhi)軸承結構的(de)螺杆泵。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

   2． 輸送(song)潤滑性較差(chà)，或溫度T＞80℃時，選(xuan)擇外置軸承(chéng)結構的螺杆(gan)泵。2. The conveyor lubrication is poorer, or temperature T > 80 ℃, select external bearing structure of the screw pump.

   3． 輸送流動(dong)性差，粘度高(gāo)的介質或對(dui)所輸送介質(zhi)進🌐行加熱或(huò)㊙️保溫時，選雙(shuāng)層加熱泵體(ti)結構的螺杆(gǎn)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(xuǎn)擇耐高溫的(de)材料制成的(de)泵或局部🈲冷(leng)卻的螺杆泵(beng)。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(li)可查閱樣本(běn)。5. About the screw pump suction capacity can refer to the samples.

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

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

   通過降低轉(zhuan)速或加熱降(jiang)低介質黏度(du)的方法，可達(dá)到高的吸上(shang)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(di)五，配套電機(ji)的選配Fifth, motor selection

   螺杆(gan)泵的型号選(xuǎn)定後，根據樣(yàng)本數據，可查(cha)到泵的軸💚功(gong)率N，該軸功率(lü)再加上一定(dìng)的功率儲備(bei)後，作為選配(pei)電機的依據(ju)，一般電機功(gong)率Nm 不小于泵(beng)軸功率N 乘以(yǐ)功率儲備系(xi)數K 所得的值(zhí)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
