   三螺杆泵(beng)(SN三螺杆泵(bèng),sm三螺杆泵(beng),spf三螺杆泵(beng))選型時，要(yao)盡可能詳(xiáng)盡地了解(jiě)泵的使用(yong)條件，除運(yun)行參數，如(rú)流量、壓力(li)須要弄清(qing)楚之外，輸(shū)送的介質(zhì)的特性如(rú)介質😘的腐(fu)蝕性，含氣(qì)量含固溶(róng)物的比率(lü)及固體顆(kē)粒的大小(xiao)以及介質(zhì)的工作溫(wēn)度、粘度、比(bi)♊重對泵内(nèi)過流元件(jiàn)🔴的腐蝕性(xìng)等和泵裝(zhuāng)置的吸入(ru)條件，安裝(zhuāng)條件均要(yào)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(xie)附在本樣(yang)本後的泵(beng)數據表，由(yóu)廠家🐅負責(ze)選⭐型，也♋可(kě)以根據樣(yang)本按以下(xia)步驟自行(hang)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(de)轉速：（SN 系列(liè)螺杆泵的(de)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(beng)轉速的選(xuǎn)擇以輸送(song)介質的粘(zhān)度和泵的(de)規格确定(dìng)轉速範圍(wei)，一般輸送(sòng)高粘度介(jiè)質時，螺杆(gǎn)泵應選低(dī)轉速；若粘(zhān)度低 ，相應(ying)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(da)規格的螺(luó)杆泵（主杆(gǎn)外徑∮60mm 以上(shàng)）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(yi)970rpm 或720rpm 的螺杆(gan)泵。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若γ＞80°E 如粘(zhan)膠液，轉速(sù)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(yu)小規格的(de)螺杆泵（主(zhu)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(huo)970rpm的螺杆泵(beng). 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(yu)螺杆泵的(de)轉速愈高(gao)摩擦功率(lü)愈高，螺杆(gǎn)泵的磨損(sǔn)💃越大💚，壽👨‍❤️‍👨命(mìng)越短，如果(guo)輸送介質(zhì)的潤滑性(xing)較差，或含(han)有微🌈量雜(zá)質，應選較(jiao)低轉速，使(shǐ)泵保持較(jiào)長的使用(yòng)壽🏃‍♀️命。推薦(jiàn)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(gou)形式的選(xuǎn)擇The choice of the form of structure

   結構的(de)選擇可根(gēn)據螺杆泵(beng)的運行環(huan)境和安裝(zhuang)環♉境，選㊙️擇(ze)合适的安(an)裝形式并(bing)遵循以下(xia)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:

   2． 輸送(sòng)潤滑性較(jiào)差，或溫度(du)T＞80℃時，選擇外(wài)置軸承結(jie)構的螺杆(gǎn)泵。2. The conveyor lubrication is poorer, or temperature T > 80 ℃, select external bearing structure of the screw pump.
