   三螺(luó)杆泵(SN三螺杆泵,sm三(san)螺杆泵,spf三螺杆泵(beng))選型時，要盡可能(neng)詳盡地了解泵的(de)使用條件，除運行(hang)參數，如流量、壓力(li)須要弄清楚之外(wài)，輸送的介質的特(te)性如介質的腐蝕(shí)性，含氣量含固溶(rong)物的比率及固體(tǐ)顆粒的大小以及(jí)介質的工作溫度(dù)、粘度、比🌈重對泵内(nèi)過流元件的腐蝕(shi)性㊙️等和泵裝置的(de)吸入🚩條件，安裝條(tiáo)件均要了解。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)可以填寫附在本(ben)樣本後的泵數據(jù)表，由廠家負責選(xuǎn)☀️型，也可以根據樣(yang)本按以下步驟自(zì)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， 确定(ding)泵的轉速：（SN 系列螺(luo)杆泵的極限轉速(su)為＜6000r.p.m）Determine the speed of the pump: (SN series screw pump limit speed for < 6000 r. p.)

   1．螺杆泵轉速的(de)選擇以輸送介質(zhi)的粘度和泵的規(guī)格💁确定轉速範圍(wéi)，一般輸送高粘度(dù)介質時，螺杆泵應(yīng)選💋低轉速；若粘度(du)💋低 ，相應選擇高轉(zhuan)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.

   對于大規格的(de)螺杆泵（主杆外徑(jing)∮60mm 以上）For the large size of screw pump (more than 30 main stem diameter of 60 mm)

   介質粘度γ＞20°E 時(shi)，轉速以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 如粘膠液，轉(zhuǎn)速可選n=200~500rpm的螺杆泵(beng)If gamma > 80 ° E, such as viscose, of optional n = 200 ~ 500 RPM of the screw pump

   對于小規格的螺(luó)杆泵（主杆外徑∮60mm 以(yǐ)下）：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(gǎn)泵. Gamma > 20 ° E, n selected 1450 RPM and 970 RPM of screw pump.

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

   2．由于螺杆泵的轉(zhuǎn)速愈高摩擦功率(lǜ)愈高，螺杆泵的⛷️磨(mó)損越大，壽命越短(duan)，如果輸送介質的(de)潤滑性較差，或含(han)有微量雜質，應選(xuǎn)較低轉速，使泵保(bǎo)持較長的使用壽(shòu)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， 結構(gòu)形式的選擇The choice of the form of structure

   結構(gòu)的選擇可根據螺(luó)杆泵的運行環境(jìng)和安裝環境，選擇(zé)合适的安裝形式(shi)并遵循以下的原(yuán)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． 輸送潤滑(hua)性較差，或溫度T＞80℃時(shi)，選擇外置軸承結(jié)構的螺杆泵。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，粘度高(gao)的介質或對所輸(shu)送介質進行加熱(re)或保溫時，選雙層(céng)加熱泵體結構的(de)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． 輸送高溫(wen)介質時，應選擇耐(nai)高溫的材料制成(cheng)的泵或局部冷卻(que)的螺杆泵。4. High temperature medium, high temperature resistant materials should be selected for the pump or cooling screw pump.

   5． 關于螺(luó)杆泵的吸入能力(li)可查閱樣本。5. About the screw pump suction capacity can refer to the samples.

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

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