   三螺杆泵(beng)(SN三螺杆泵,sm三(sān)螺杆泵,spf三螺(luo)杆泵)選型時(shí)，要盡可能詳(xiáng)盡地了解泵(beng)的使用條件(jian)，除運行🏃🏻‍♂️參⭐數(shu)，如流量、壓力(lì)須要弄清楚(chu)之外，輸送的(de)介質的特性(xìng)如介質㊙️的腐(fǔ)蝕性，含氣量(liàng)含固溶物的(de)比率及固體(ti)☔顆粒的大小(xiao)以💛及介質的(de)工作溫度、粘(zhan)度、比重對泵(beng)内過流元件(jian)的腐蝕性等(děng)和泵裝置的(de)吸入🍉條件，安(an)裝條件均要(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.

   用戶可(kě)以填寫附在(zai)本樣本後的(de)泵數據表，由(you)廠家負責選(xuan)♌型🥵，也可以根(gēn)據樣本按以(yǐ)下步驟自行(háng)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(sù)：（SN 系列螺杆泵(bèng)的極限轉速(su)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(zhuǎn)速的選擇以(yǐ)輸送介質的(de)粘度和泵的(de)規格确定轉(zhuǎn)💚速範圍，一般(ban)輸送高粘度(dù)介質時，螺杆(gǎn)泵應選低轉(zhuan)速；若粘度低(di) ，相應選擇高(gāo)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.

   對于大(da)規格的螺杆(gǎn)泵（主杆外徑(jìng)∮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(yǐ)970rpm 或720rpm 的螺杆泵(beng)。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若γ＞80°E 如粘膠液(yè)，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(yu)小規格的螺(luó)杆泵（主杆外(wai)徑∮60mm 以下）：For small specifications of the screw pump (below 30 main stem diameter of 60 mm) :

   γ＞20°E 時，n 選(xuǎn)1450rpm 或970rpm的螺杆泵(bèng). Gamma > 20 ° E, n selected 1450 RPM and 970 RPM of screw pump.

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

   2．由于螺杆(gǎn)泵的轉速愈(yu)高摩擦功率(lǜ)愈高，螺杆泵(beng)的磨損🙇🏻越大(da)，壽🆚命越短，如(ru)果輸送介質(zhì)的潤滑性較(jiào)差，或含🆚有微(wēi)量雜質，應選(xuǎn)較低轉速，使(shǐ)泵保持較長(zhang)的使用壽命(mìng)。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(jie)構形式的選(xuan)擇The choice of the form of structure

   結構的選(xuǎn)擇可根據螺(luó)杆泵的運行(hang)環境和安裝(zhuāng)環境，選擇🌍合(he)适的安裝形(xing)式并遵循以(yǐ)下的原則：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(shū)送潤滑性油(you)類，且溫度T＜80℃時(shí)，選擇内置軸(zhóu)承結構的螺(luó)杆泵。1. Conveyor lubrication oil, and temperature T < 80 ℃, choose built-in bearing structure of the screw pump.

   2． 輸送潤(run)滑性較差，或(huo)溫度T＞80℃時，選擇(zé)外置軸承結(jie)構的螺杆泵(beng)。2. The conveyor lubrication is poorer, or temperature T > 80 ℃, select external bearing structure of the screw pump.

   3． 輸送流動性(xing)差，粘度高的(de)介質或對所(suo)輸送介質進(jìn)行加熱或保(bao)溫時，選雙層(ceng)加熱泵體結(jié)構的螺杆泵(beng)。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． 輸送高溫介(jie)質時，應選擇(zé)耐高溫的材(cái)料制成的泵(bèng)或局🙇‍♀️部冷卻(que)的螺杆泵。4. High temperature medium, high temperature resistant materials should be selected for the pump or cooling screw pump.

   5． 關(guān)于螺杆泵的(de)吸入能力可(ke)查閱樣本。5. About the screw pump suction capacity can refer to the samples.

   第(di)三， 螺杆泵材(cái)料組合的選(xuǎn)擇 見上表Third, the choice of the screw pump material combination See the table above

   第(di)四， 螺杆泵的(de)吸上能力Fourth, the screw pump suction on ability

   通(tōng)過降低轉速(sù)或加熱降低(dī)介質黏度的(de)方法，可達✂️到(dao)高的🐇吸上㊙️性(xìng)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(wu)，配套電機的(de)選配Fifth, motor selection

   螺杆泵(beng)的型号選定(dìng)後，根據樣本(běn)數據，可查到(dào)泵的軸功率(lǜ)N，該軸功率再(zài)加上一定的(de)功率儲備後(hòu)，作為選配電(dian)機的依據，一(yi)般電機功率(lü)Nm 不小于泵軸(zhóu)功率N 乘以功(gōng)率儲備系數(shù)K 所得的值即(ji)：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
