   三螺杆(gǎn)泵(SN三螺(luo)杆泵,sm三(sān)螺杆泵(bèng),spf三螺杆(gǎn)泵)選型(xíng)時，要盡(jìn)可能詳(xiáng)盡地了(le)解泵的(de)使用條(tiáo)件，除運(yun)行參數(shu)✂️，如♍流量(liàng)、壓力須(xu)要弄清(qīng)楚之外(wai)，輸送的(de)介質的(de)特✔️性如(rú)介質的(de)腐蝕性(xìng)，含氣量(liang)含固溶(róng)物的比(bi)率及固(gù)體顆粒(lì)的大小(xiao)以及介(jie)質的工(gōng)作溫度(dù)、粘度、比(bǐ)重對泵(bèng)内過流(liu)元件☀️的(de)腐蝕性(xìng)☂️等和泵(bèng)裝置的(de)吸入條(tiao)件，安裝(zhuang)條件均(jun)要了解(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.

   用戶可(ke)以填寫(xie)附在本(běn)樣本後(hou)的泵數(shu)據表，由(you)廠家負(fù)責選😘型(xíng)，也👣可以(yǐ)根據樣(yàng)本按以(yǐ)下步驟(zhòu)自行選(xuǎn)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(yi)， 确定泵(beng)的轉速(sù)：（SN 系列螺(luo)杆泵的(de)極限轉(zhuan)速為＜6000r.p.m）Determine the speed of the pump: (SN series screw pump limit speed for < 6000 r. p.)

   1．螺(luo)杆泵轉(zhuan)速的選(xuan)擇以輸(shū)送介質(zhì)的粘度(dù)和泵的(de)規格😄确(què)定轉🐇速(sù)範圍，一(yī)般輸送(song)高粘度(dù)介質時(shí)，螺杆泵(beng)應選低(di)轉速；若(ruò)粘度🔴低(di) ，相應選(xuǎn)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(yú)大規格(ge)的螺杆(gan)泵（主杆(gǎn)外徑∮60mm 以(yǐ)上）For the large size of screw pump (more than 30 main stem diameter of 60 mm)

   介質(zhì)粘度γ＞20°E 時(shí)，轉速以(yǐ)970rpm 或720rpm 的螺(luo)杆泵。Medium viscosity gamma > 20 ° E, screw pump speed to 970 RPM and 720 RPM.

   若(ruò)γ＞80°E 如粘膠(jiāo)液，轉速(sù)可選n=200~500rpm的(de)螺杆泵(beng)If gamma > 80 ° E, such as viscose, of optional n = 200 ~ 500 RPM of the screw pump

   對于小(xiao)規格的(de)螺杆泵(beng)（主杆外(wai)徑∮60mm 以下(xia)）：For small specifications of the screw pump (below 30 main stem diameter of 60 mm) :

   γ＞20°E 時，n 選1450rpm 或(huò)970rpm的螺杆(gan)泵. 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(gǎn)泵。Gamma > 80 ° E, n selected 300 ~ 600 RPM of the screw pump.

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(tè)點：1. Features:

　 1）三螺(luo)杆泵(3GR三(sān)螺杆泵(beng),SNH三螺杆(gan)泵)的均(jun1)勻流量(liang)與齒數(shu)成正比(bi)，而與模(mó)數的平(ping)方成比(bǐ)例。體積(ji)小，重量(liàng)輕，結構(gou)簡樸，制(zhi)造利便(biàn)，價格低(dī)，工作㊙️可(ke)靠，自吸(xī)機能較(jiào)好，對油(you)⚽液污染(ran)不敏感(gan)，維護利(lì)便等。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(sān)螺杆泵(bèng)的流量(liang)與齒寬(kuān)成正比(bǐ)，但齒寬(kuan)的增大(dà)受齒輪(lun)所受液(ye)壓徑向(xiang)力增加(jiā)的限制(zhi)，一般取(qǔ)齒寬B＝（6～10）m，高(gao)壓時取(qu)小值。另(lìng)外，在容(rong)積式液(yè)壓泵中(zhōng)，三螺杆(gan)泵的流(liú)量💃🏻脈動(dòng)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)步轉速(sù)可以進(jin)步泵的(de)流量，但(dàn)受泵吸(xī)入機能(neng)的限制(zhì)。齒輪泵(beng)的轉速(sù)一般在(zài)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、三螺杆(gan)泵(3GR三螺(luó)杆泵,SNH三(san)螺杆泵(beng))壓力的(de)措施

　 端(duān)面間隙(xì)自動補(bǔ)償原理(lǐ)：

　 利用特(tè)制的通(tong)道把三(san)螺杆泵(bèng)内壓油(you)腔的壓(yā)力油引(yǐn)🌈到浮動(dòng)軸套的(de)外側，作(zuò)用在一(yi)定外形(xing)和大小(xiao)的🚶面積(jī)上，産生(shēng)液壓作(zuò)用力，使(shǐ)軸套壓(ya)向齒輪(lun)端面，這(zhe)個力必(bì)需大于(yú)☁️齒輪端(duān)面作用(yòng)在軸套(tào)内側的(de)作用力(lì)，才能保(bao)✊證在各(ge)種壓力(li)下，軸套(tào)始終自(zì)♈動貼緊(jin)齒輪端(duan)面，減小(xiǎo)三螺杆(gan)泵内通(tōng)過端面(miàn)的洩漏(lòu)，達到進(jìn)步壓力(li)的目的(de)。其缺點(dian)是：流量(liang)♌和壓力(li)脈動較(jiào)大，噪聲(shēng)大，排量(liang)不可變(biàn)等。

　 ３.三螺(luo)杆泵(3GR三(sān)螺杆泵(beng),SNH三螺杆(gan)泵)的困(kun)油現象(xiàng)及卸荷(hé)

　 困油現(xiàn)象的危(wei)害：

　 使閉(bì)死容積(ji)中的壓(yā)力急劇(ju)升高，使(shǐ)軸承受(shou)到很大(dà)的📱附加(jiā)🏃🏻‍♂️載荷，同(tóng)時産生(sheng)功率損(sun)失及液(ye)體發燒(shao)等不良(liang)現象；溶(rong)解于液(yè)體中的(de)空氣便(bian)析生産(chǎn)氣憤泡(pào)，産氣憤(fen)蝕現象(xiang)，引起振(zhèn)動和噪(zao)聲。

　 消除(chú)困油現(xian)象：

　 在三(sān)螺杆泵(bèng)(3GR三螺杆(gǎn)泵,SNH三螺(luó)杆泵)的(de)側闆上(shang)或浮動(dòng)軸套上(shang)開卸荷(hé)槽。非對(dui)稱式，必(bì)需保證(zhèng)在🐕任何(hé)時候都(dōu)不能使(shǐ)吸油腔(qiāng)與壓油(yóu)腔相互(hu)串通📐；這(zhè)樣的齒(chi)輪泵不(bu)能反轉(zhuǎn)。三螺杆(gǎn)泵(3GR三螺(luó)杆泵,SNH三(sān)螺杆泵(beng))在使用(yong)中注意(yì)不同形(xing)式的特(tè)點和性(xing)能，在使(shǐ)用中⁉️經(jīng)常出現(xian)不同的(de)問題和(he)反應，在(zai)使用中(zhōng)保證正(zhèng)常⭕的使(shǐ)用，出現(xiàn)問👌題及(ji)時進行(hang)解決，對(dui)不同的(de)方面進(jìn)行控制(zhì)🚶，按照正(zhèng)常的方(fāng)式進行(hang)。
