   三(sān)螺杆泵(sn三螺(luó)杆(gǎn)泵,sm三螺杆(gǎn)泵,spf三(sān)螺杆泵)選型時(shí)，要盡(jìn)可(kě)能(néng)詳盡(jìn)地了解(jiě)泵(bèng)的使(shǐ)用條件，除運行(háng)參數，如流量、壓(yā)力須要(yào)弄清楚(chǔ)之外，輸送的介質的(de)特性如介(jiè)質的腐(fǔ)蝕性，含氣量(liàng)含固(gù)溶物(wù)的比率(lǜ)及固體(tǐ)顆粒的大(dà)小以(yǐ)及介質的工作(zuò)溫度、粘度、比重(zhòng)對泵内過流元(yuán)件的腐蝕(shí)性等(děng)和泵裝置的吸(xī)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.

   用戶可以(yǐ)填(tián)寫附(fù)在本樣本後的(de)泵數(shù)據表，由廠(chǎng)家負(fù)責選(xuǎn)型，也(yě)可以根據樣本(běn)按以(yǐ)下步(bù)驟自行選型。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(què)定泵的轉(zhuǎn)速：（sn 系(xì)列螺杆泵的極(jí)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(zhuǎn)速的選擇(zé)以輸送(sòng)介質的(de)粘度(dù)和泵的規(guī)格(gé)确定轉速範(fàn)圍，一(yī)般輸送高粘度介質(zhì)時，螺(luó)杆泵(bèng)應選低轉(zhuǎn)速；若粘度(dù)低 ，相應選(xuǎn)擇高轉速(sù)。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(dà)規格的(de)螺杆(gǎn)泵（主(zhǔ)杆外徑∮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(shí)，轉(zhuǎn)速(sù)以970rpm 或720rpm 的螺(luó)杆泵。medium viscosity gamma > 20 ° e, screw pump speed to 970 rpm and 720 rpm.

   若γ＞80°e 如(rú)粘膠液，轉速可(kě)選n=200~500rpm的螺杆(gǎn)泵if gamma > 80 ° e, such as viscose, of optional n = 200 ~ 500 rpm of the screw pump

   對(duì)于小(xiǎo)規格的螺(luó)杆泵（主杆(gǎn)外徑(jìng)∮60mm 以下）：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(de)螺杆泵. gamma > 20 ° e, n selected 1450 rpm and 970 rpm of screw pump.

   γ＞80°e 時(shí)，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(luó)杆泵的(de)轉(zhuǎn)速愈(yù)高摩(mó)擦功(gōng)率愈(yù)高，螺杆泵的磨損越大，壽命越(yuè)短，如(rú)果輸送介(jiè)質的(de)潤(rùn)滑性較(jiào)差，或含有微量(liàng)雜質，應(yīng)選較低(dī)轉速，使泵保(bǎo)持較長(zhǎng)的使(shǐ)用壽(shòu)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.
