   三螺(luó)杆泵(sn三螺(luó)杆泵(bèng),sm三螺(luó)杆泵(bèng),spf三螺杆泵)選型(xíng)時，要盡可(kě)能詳(xiáng)盡(jìn)地了解泵的(de)使(shǐ)用條件(jiàn)，除運行參(cān)數，如流量、壓力須要(yào)弄清(qīng)楚(chǔ)之(zhī)外，輸(shū)送(sòng)的介(jiè)質(zhì)的特(tè)性如介質的腐(fǔ)蝕性(xìng)，含氣量含固溶物的(de)比率(lǜ)及固體(tǐ)顆粒的(de)大小以及(jí)介質(zhì)的工(gōng)作溫度、粘(zhān)度、比重對(duì)泵内(nèi)過流(liú)元(yuán)件(jiàn)的腐(fǔ)蝕性(xìng)等和(hé)泵裝(zhuāng)置的吸入條件(jiàn)，安裝條件均要(yào)了解(jiě)。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(yòng)戶(hù)可以填寫(xiě)附(fù)在本樣(yàng)本後(hòu)的泵數據表(biǎo)，由(yóu)廠(chǎng)家(jiā)負責(zé)選型，也可以根(gēn)據樣本按以下(xià)步驟自(zì)行選型(xíng)。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， 确定泵的(de)轉速：（sn 系列螺杆(gǎn)泵的極限轉速(sù)為＜6000r.p.m）determine the speed of the pump: (sn series screw pump limit speed for < 6000 r. p.)

   1．螺(luó)杆泵(bèng)轉速的選擇以(yǐ)輸送介質的粘度和泵的(de)規格确定(dìng)轉速範圍，一般輸送高粘(zhān)度介(jiè)質時(shí)，螺杆泵應(yīng)選低(dī)轉速(sù)；若粘(zhān)度(dù)低(dī) ，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.

   對于大(dà)規格的螺杆泵(bèng)（主杆外徑∮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(zhuǎn)速以(yǐ)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(yè)，轉速可選(xuǎn)n=200~500rpm的螺(luó)杆泵(bèng)if gamma > 80 ° e, such as viscose, of optional n = 200 ~ 500 rpm of the screw pump

   對于小規(guī)格的(de)螺杆(gǎn)泵（主(zhǔ)杆外(wài)徑∮60mm 以下）：for small specifications of the screw pump (below 30 main stem diameter of 60 mm) :

   γ＞20°e 時(shí)，n 選1450rpm 或970rpm的(de)螺杆泵(bèng). gamma > 20 ° e, n selected 1450 rpm and 970 rpm of screw pump.

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

   2．由于(yú)螺杆泵的(de)轉速愈高摩擦(cā)功率愈(yù)高，螺杆(gǎn)泵的磨損越大(dà)，壽命(mìng)越短，如果(guǒ)輸送介質的潤(rùn)滑性較差，或含(hán)有微量雜質，應(yīng)選較低轉(zhuǎn)速，使(shǐ)泵保(bǎo)持(chí)較長的(de)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(èr)， 結構形式(shì)的選(xuǎn)擇the choice of the form of structure

   2． 輸送(sòng)潤滑(huá)性較差，或(huò)溫度t＞80℃時(shí)，選(xuǎn)擇外置軸承(chéng)結構的(de)螺杆(gǎn)泵。2. the conveyor lubrication is poorer, or temperature t > 80 ℃, select external bearing structure of the screw pump.

   3． 輸(shū)送流動性差，粘度高(gāo)的介質或對所(suǒ)輸送介質進行(háng)加熱或保溫時，選雙(shuāng)層加(jiā)熱泵體(tǐ)結(jié)構的(de)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(shū)送高(gāo)溫(wēn)介(jiè)質時(shí)，應選(xuǎn)擇耐(nài)高溫的材(cái)料制(zhì)成的(de)泵或(huò)局部冷(lěng)卻的螺杆泵(bèng)。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)的吸入能力可查(chá)閱樣本。5. about the screw pump suction capacity can refer to the samples.

   第五，配套電機(jī)的(de)選配(pèi)fifth, motor selection

   螺杆(gǎn)泵的型号(hào)選定後(hòu)，根(gēn)據樣(yàng)本數據，可查到泵的軸功(gōng)率n，該(gāi)軸功率再加上一定的功率儲備後，作為選配(pèi)電機的依(yī)據，一(yī)般電機功率nm 不(bú)小于泵(bèng)軸(zhóu)功率(lǜ)n 乘以(yǐ)功率儲備(bèi)系數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

　　三螺杆(gǎn)泵(bèng)能夠在不(bú)同的行業中使(shǐ)用，在(zài)其中能夠發揮重要的作用和(hé)性能(néng)，在(zài)行業(yè)中(zhōng)能夠(gòu)充分展現(xiàn)良好(hǎo)的性能優(yōu)勢，在産業性能(néng)中發揮重要的(de)作用(yòng)和貢獻。下(xià)面從特點.困油(yóu)及措(cuò)施不平衡(héng)等方面(miàn)向(xiàng)大家(jiā)介紹(shào)一下(xià)三螺(luó)杆泵(3gr三螺(luó)杆泵(bèng),snh三螺(luó)杆泵). three screw pump can be used in different industries, in which can play an important role and performance, can fully show the good performance advantages in the industry, play an important role in industry performance and contribution.from below. trapped oil and measures unbalance introduce three screw pump (3 gr three screw pump, three screw pump snh).

　 1. 特點(diǎn)：1. features:

　 1）三螺杆(gǎn)泵(bèng)(3gr三螺杆泵(bèng),snh三螺杆泵(bèng))的(de)均(jun1)勻流量與(yǔ)齒數成正比，而(ér)與模(mó)數(shù)的(de)平方(fāng)成比(bǐ)例。體積小(xiǎo)，重量(liàng)輕，結(jié)構簡樸，制造利(lì)便，價(jià)格低，工作(zuò)可靠，自吸機能較好(hǎo)，對油液污染不(bú)敏感(gǎn)，維護利便(biàn)等。1) the three screw pump (3 gr three screw pump, three screw pump snh) uniform flow rate is proportional to the number of teeth, and with the square of the modulus ratio.small volume, light weight, simple structure, manufacture, then, low prices, reliable work, self-priming function is good, is not sensitive to oil pollution, maintenance, etc.

　 2）三螺杆(gǎn)泵的(de)流量(liàng)與齒寬成正比，但齒(chǐ)寬的增大(dà)受齒(chǐ)輪所(suǒ)受液壓徑向力增加的限制，一(yī)般取齒寬(kuān)b＝（6～10）m，高壓(yā)時取小(xiǎo)值。另外，在容積式(shì)液壓(yā)泵中(zhōng)，三(sān)螺杆泵的流量脈(mò)動最大。2) three screw pump flow rate is proportional to the tooth width, but the increase of tooth width is restricted by the hydraulic radial force increased by gear, generally take tooth width b = (6 ~ 10) m, when the high pressure of little value.in addition, in the positive displacement hydraulic pump, three screw pump flow pulsation is the largest.

　 3）進(jìn)步轉(zhuǎn)速可(kě)以進步泵(bèng)的流量，但(dàn)受泵吸入(rù)機能的限(xiàn)制。齒(chǐ)輪泵(bèng)的(de)轉速一(yī)般在1000～1500r/min。3) progress speed can progress the flow of the pump, but restricted by pump suction function.the speed of the gear pump is in commonly 1000 ~ 1500 r/min.

　 2、三螺(luó)杆泵(3gr三螺(luó)杆(gǎn)泵,snh三螺杆泵(bèng))壓力的措(cuò)施

　 端面間隙自(zì)動補(bǔ)償原(yuán)理：

　 利(lì)用特(tè)制的通道(dào)把三螺杆(gǎn)泵内(nèi)壓油腔(qiāng)的(de)壓力油引到浮動軸(zhóu)套(tào)的(de)外側(cè)，作用(yòng)在一定外形和大小的面積上(shàng)，産生液壓作用(yòng)力，使軸套壓向(xiàng)齒輪端面(miàn)，這個力必需大于齒(chǐ)輪端面(miàn)作(zuò)用在(zài)軸套内側的作(zuò)用力(lì)，才能(néng)保證(zhèng)在各(gè)種壓力下(xià)，軸套始(shǐ)終(zhōng)自動(dòng)貼緊(jǐn)齒輪端面，減小三螺(luó)杆泵(bèng)内通(tōng)過(guò)端面的(de)洩漏，達到進步(bù)壓力的(de)目的。其(qí)缺點是(shì)：流量和壓力(lì)脈動較大(dà)，噪聲大，排(pái)量不(bú)可變(biàn)等。

　 ３.三螺杆(gǎn)泵(3gr三(sān)螺杆(gǎn)泵,snh三(sān)螺杆(gǎn)泵)的(de)困油(yóu)現象及(jí)卸荷

　 困(kùn)油現(xiàn)象的危害(hài)：

　 使(shǐ)閉死容(róng)積中(zhōng)的壓力急劇升(shēng)高，使軸承(chéng)受到很大的附加載(zǎi)荷，同時産生功(gōng)率損失及液體(tǐ)發燒等不良(liáng)現象；溶(róng)解于(yú)液體(tǐ)中的空(kōng)氣便析生産氣(qì)憤泡，産(chǎn)氣憤蝕現(xiàn)象，引(yǐn)起振動和噪聲。

　 消除困油現象(xiàng)：

　 在三螺杆泵(3gr三螺杆泵,snh三螺杆(gǎn)泵)的側闆上或(huò)浮動軸套上開(kāi)卸荷槽。非(fēi)對稱(chēng)式，必需(xū)保證在(zài)任何時(shí)候都不能(néng)使(shǐ)吸油腔與壓油腔(qiāng)相(xiàng)互串通；這樣(yàng)的(de)齒輪(lún)泵不(bú)能(néng)反轉。三(sān)螺杆泵(3gr三(sān)螺杆泵,snh三螺杆泵)在(zài)使用中(zhōng)注意(yì)不(bú)同形式的特點(diǎn)和性能，在(zài)使用中經(jīng)常(cháng)出現不(bú)同的問(wèn)題和反(fǎn)應，在使用(yòng)中(zhōng)保(bǎo)證正常的使用(yòng)，出現問題(tí)及時(shí)進行解決(jué)，對不同的方面進行(háng)控制，按照正常(cháng)的方式進行。
