    ●雙螺杆泵可(kě)分(fèn)為内置軸承(chéng)和外置軸(zhóu)承兩(liǎng)種(zhǒng)形(xíng)式。在(zài)内置軸承的(de)結(jié)構型式中(zhōng)軸承(chéng)由輸送(sòng)物(wù)進行(háng)潤滑。外置軸承(chéng)結構的雙(shuāng)螺杆泵工作腔同軸承是分開的。由于這種(zhǒng)泵(bèng)的結(jié)構和螺杆間存(cún)在的(de)側(cè)間隙，它(tā)可以(yǐ)輸送非潤(rùn)滑性(xìng)介質(zhì)。此外(wài)，調整同步(bù)齒輪(lún)使得螺杆不接(jiē)觸，同(tóng)時将輸出(chū)扭矩的一半(bàn)傳(chuán)給從動螺杆。正如所有螺(luó)杆泵(bèng)一樣(yàng)，外置(zhì)軸承式雙(shuāng)螺杆泵也(yě)有自吸能力，而且多(duō)數泵輸送(sòng)元件(jiàn)本身都是雙吸對稱布置(zhì)，可消除軸向力(lì)，也有(yǒu)很大的吸(xī)高。double screw pump can be divided into internal bearing and the outer bearing two forms.in the built-in bearing structure bearing lubrication by conveying material.working with external bearing structure of the double screw pump bearings are separated.owing to the pump structure and side clearance between screw, it can transport non-lubricative medium.in addition, the adjustment of the synchronous gear makes the screw does not contact, at the same time the output torque of the half to driven screw.like all of the screw pump, external bearing type twin-screw pump, and most are double suction pump element itself symmetric arrangement, can eliminate the axial force, also has a lot of high absorption.
    ●雙(shuāng)螺杆泵系列産(chǎn)品分為單吸雙螺杆泵和雙吸(xī)雙(shuāng)螺杆泵(bèng)兩大類(lèi)。該系(xì)列産品具有(yǒu)特殊(shū)的螺杆型(xíng)線和(hé)與之配(pèi)套的特(tè)殊(shū)結(jié)構(gòu)，廣泛适(shì)用于(yú)石(shí)油、化工(gōng)、冶金、鋼鐵(tiě)、電力、船舶(bó)、制(zhì)藥、食品(pǐn)、建材等各種行業，其适用介質(zhì)之多、輸送(sòng)範圍(wéi)之廣、應用工況(kuàng)之複雜(zá)是其它(tā)泵類(lèi)産品無法(fǎ)比拟的(de)。這些特(tè)點也(yě)使得(dé)該(gāi)系(xì)列泵具有潛在(zài)的使用(yòng)發(fā)展前(qián)景。double screw pump series products are divided into single suction of two kinds of double screw pump and double suction double screw pump.this series of products have special screw lines and form a complete set with the special structure, widely used in petroleum, chemical industry, metallurgy, steel, electricity, shipbuilding, pharmaceutical, food, building materials and other industries, by as much as its applicable medium, transmission range wide, application condition of the complex is unmatched by other pump product.these features also makes the use of this series of pumps with potential development prospects.
    ●泵(bèng)體内(nèi)裝有(yǒu)兩根左、有施單(dān)頭螺紋的(de)螺杆(gǎn)，主動(dòng)螺杆(gǎn)2由動(dòng)力機驅(qū)動(dòng)轉動時，靠同步(bù)齒輪(lún)1帶動從動(dòng)螺杆(gǎn)3轉動(dòng)。兩根(gēn)螺杆以及(jí)螺杆與泵(bèng)體. 之(zhī)間(jiān)存在着間隙(xì)，該間隙靠齒輪和軸承保(bǎo)證。其間隙(xì)大小，取決(jué)于液(yè)體粘(zhān)度、工(gōng)作(zuò)壓力等(děng)因素(sù)。由于每根(gēn)螺杆兩端螺紋的旋(xuán)向(xiàng)相反，螺(luó)杆轉(zhuǎn)動時(shí)，由螺(luó)杆齧合線(xiàn)形成(chéng)的泵工作腔。equipped with two left in the pump body, a single thread screw, active screw driven by engine 2 turns, driven by synchronous gear 1 driven screw 3 rotation.two screw and screw and pump body. there is a gap between the gap by gear and bearing.the gap size, depends on the liquid viscosity, pressure and other factors.because each thread rotate to the opposite on both ends of the screw, the screw rotates, formed by the screw meshing line pump working chamber.
 
 
   ●該(gāi)型泵(bèng)采用雙吸(xī)式結構，螺杆兩端處于同一壓(yā)力腔(qiāng)中(zhōng)，軸(zhóu)向力(lì)可以(yǐ)自行平衡。兩端軸承采用(yòng)外裝(zhuāng)式，單獨(dú)采(cǎi)用潤滑油(脂)潤(rùn)滑，因(yīn)而不受輸送介(jiè)質(zhì)的(de)影響(xiǎng)。兩螺杆(gǎn)間(jiān)用一(yī)對同步齒(chǐ)輪驅(qū)動，螺杆齒(chǐ)面間(jiān)并不接(jiē)觸(chù)，而留(liú)有一微小間隙(xì)，介質中的雜質(zhì)并不能(néng)對螺杆齒面産(chǎn)生直接(jiē)的磨損(除沖刷(shuā)外)。 除一些小排(pái)量泵外(2w.w4.0以下)，一(yī)般在泵體(tǐ)上都帶有内流式安(ān)全閥，當排(pái)放壓(yā)力超過(guò)額定值時(shí)，有一定的保護作用(yòng)。 泵體上(shàng)的進出口(kǒu)方向(xiàng)有兩種(zhǒng)，一為水(shuǐ)平進，水平出;二為(wéi)水平進，垂直(zhí)向上出;用(yòng)戶可(kě)根據自己需要(yào)選擇。this type pump adopts double suction type structure, at the same pressure in the cavity on both ends of the screw, the axial force can balance itself.both ends of bearing mounted outside using, lubricated by lubricating oil (grease) separately, and therefore not affected by the medium.with a pair of synchronous gears drive between the two screw, the screw does not contact between tooth surfaces, and leave a small gap, the impurities in medium can not be directly on the screw tooth surface wear (except wash).except a few small displacement pump (below 2 w. w4.0), generally contain flow relief valve on the pump body, when the discharge pressure exceeds rating, has certain protective effect.there are two kinds of the direction of the import and export on the pump body, one for level, level;secondly, level, vertical;user can choose according to their own needs.
 
 
  
   ●性能(néng)參數(shù)的選(xuǎn)擇：
    1. 流量 q ：
    作(zuò)為容積式(shì)泵，影(yǐng)響雙(shuāng)螺(luó)杆泵流(liú)量的因素主要(yào)有轉(zhuǎn)速 n ，壓(yā)力 p ，以(yǐ)及介質的粘度 v 。the selection of performance parameters:
1. the flow q:
as a positive displacement pump, double screw pump flow effects are the major factors of rotational speed n, pressure p, and the medium viscosity v.
    1.1 轉速(sù) n 的影響：
    螺(luó)杆泵(高(gāo)溫(wēn)雙螺(luó)杆泵(bèng),大流量雙(shuāng)螺杆(gǎn)泵(bèng))在(zài)工作(zuò)時，兩(liǎng)螺杆及襯套之(zhī)間(jiān)形成密(mì)封腔，螺(luó)杆(gǎn)每轉(zhuǎn)動一周便由進口向出口移出(chū)一個(gè)密封腔，即(jí)一個密(mì)封腔的(de)體積的液(yè)體(tǐ)被(bèi)排出去。理(lǐ)想狀态下，泵内部無洩漏，那(nà)麼(me)泵的(de)流量與(yǔ)轉速成(chéng)正比(bǐ)。即： qth=n*q n---- 轉速； 　q---- 理(lǐ)論排量，即(jí)泵每轉一(yī)周(zhōu)所排出(chū)的液體體積；　qth---- 理(lǐ)論排量。the influence of the rotational speed n 1.1:screw pump (high temperature double screw pump, large flow of double screw pump) at work, the sealed cavity formed between the two screw and bushing, the screw rotation per week will remove a sealed cavity from import to export, that is, a sealed cavity volume of liquid is out.internal leak-off ideally, pump, the pump flow rate is proportional to the speed.namely: qth q = n * n - speed;q - the theory of displacement, the pump discharge by turn every week liquid volume;qth - the theory of displacement.
    1.2 壓力 △ p 的(de)影響：
    雙螺杆泵(bèng)(高溫雙(shuāng)螺杆泵(bèng),大流量雙螺杆(gǎn)泵)實際(jì)工作過程中，其内部存(cún)在洩(xiè)漏，也稱滑移量。由(yóu)于(yú)泵的(de)密封腔有一定(dìng)的間(jiān)隙，且密封(fēng)腔(qiāng)前(qián)、後存在壓(yā)差 △ p ，因此，有一部(bù)分液體回流，即(jí)存在洩漏，洩漏(lòu)量用 △ q 表示，則 q=qth- △ q.顯(xiǎn)而易見，随(suí)着密封腔前、後壓差 △ p 升高(gāo)，洩漏量 △ q 逐(zhú)漸增大。對于不(bú)同型線和結構，影(yǐng)響大(dà)小也各(gè)不相(xiàng)同(tóng)。the influence of pressure delta p 1.2:
double screw pump (high temperature double screw pump, large flow of double screw pump) in the process of the actual work, its internal is leaking, also known as slippage.due to pump seal chamber has a certain gap, and seal chamber before and after the differential delta p, as a result, some liquid reflux, is leakage, leakage in delta q, q = qth - delta q. obviously, as the seal chamber pressure difference before and after the delta p increases, leakage delta q increases gradually.for different lines and structure, effect size are different.
    1.3 粘度 v 的(de)影響：試(shì)想：将清水和(hé)粘(zhān)稠的漿(jiāng)糊以(yǐ)相(xiàng)同(tóng)的體(tǐ)積從漏鬥式的(de)容器中洩漏出(chū)去。顯然水(shuǐ)比漿(jiāng)糊要洩(xiè)漏(lòu)得快(kuài)。同理，對于(yú)雙螺(luó)杆(gǎn)泵(bèng)，粘度大的(de)流體比粘度小(xiǎo)的液體的(de)洩漏(lòu)要小，洩漏量與介質粘度有一定的比例關系(xì)。綜上(shàng)所述，要綜合地考慮(lǜ)以上各種(zhǒng)因(yīn)素，通過(guò)一系(xì)列的計算(suàn)才能(néng)精确地知(zhī)道泵的實際流(liú)量是(shì)否符(fú)合工(gōng)況要求(qiú)。the influence of the viscosity of 1.3 v: just think: will clear water and the volume of the sticky paste with the same leak out from the funnel type of container.obviously water leak faster than paste.similarly, for double screw pump, the viscosity of the fluid is larger than that of low viscosity liquid leakage, leakage and the proportion of medium viscosity have a certain relationship.above all, should be synthetically considered the above factors, through a series of calculations to accurately know the actual flow of the pump is in accordance with the working condition requirements.
    2. 壓力 △ p ：
    與(yǔ)離心(xīn)泵不同，雙(shuāng)螺杆泵的(de)工作(zuò)壓力(lì) △ p 由出口負(fù)載決定(dìng)，即(jí)出口(kǒu)阻力來決定。出(chū)口阻力與泵的出口處的壓力(lì)是匹配的(de)，出(chū)口(kǒu)阻力越大，工作(zuò)壓力(lì)也越(yuè)大。若想知道壓(yā)力，則(zé)需要用流體力(lì)學的知識對出(chū)口阻(zǔ)力精(jīng)确的計算(suàn)。2. pressure delta p:
unlike centrifugal pump, double screw pump working pressure delta p is determined by export load, namely export resistance to decide.export resistance is matching with the pump outlet pressure, export the resistance, the greater the pressure of work.if want to know the pressure, you may need to drag on exports by the knowledge of fluid mechanics calculations.
    3. 軸功(gōng)率 n ：
    雙螺杆(gǎn)泵(高溫雙(shuāng)螺杆(gǎn)泵,大流量(liàng)雙螺杆泵)的軸功率分為(wéi)兩部(bù)分，即： nth---- 液壓功率，即壓(yā)力(lì)液體的(de)能(néng)量； 　nr---- 摩擦功率。3. the shaft power n:
double screw pump (high temperature double screw pump, large flow of double screw pump) of the shaft power is divided into two parts, i.e., the nth, hydraulic power, namely of liquid pressure energy;nr - friction power.
    對于确定(dìng)的壓(yā)力和(hé)流量(liàng)，其液(yè)壓功率是一定(dìng)的，因此影響軸(zhóu)功率的(de)因素為(wéi)摩擦率 nr 。
    摩擦功(gōng)率是由于(yú)運動(dòng)部件的摩(mó)擦而(ér)消耗的(de)那部分(fèn)功率(lǜ)。這(zhè)些摩擦功率顯(xiǎn)然是随(suí)着工作壓差的(de)增加而增(zēng)加的(de)，并且(qiě)介質(zhì)粘度的增(zēng)加也會引(yǐn)起液(yè)體(tǐ)摩(mó)擦功率的增(zēng)加。to determine the pressure and flow rate, the hydraulic power is certain, so the influence of shaft power factor for the friction ratio of nr.friction power is due to the friction in the moving parts and the part of the power consumption.the friction power is obviously increases with the increase of the pressure difference, and the increase of viscosity of medium can also cause the liquid friction power increases.
    由此(cǐ)，泵的軸(zhóu)功率除了液壓(yā)功(gōng)率外(wài)，其(qí)中(zhōng)摩擦功率(lǜ)随介質粘(zhān)度及(jí)工作壓力而增(zēng)加，因(yīn)此(cǐ)在選擇(zé)配套電機(jī)時，介(jiè)質的(de)粘度也是(shì)一個(gè)非常重要(yào)的參考數(shù)據。尤其在輸(shū)送高粘度介(jiè)質時，需要(yào)作比較精(jīng)确的(de)計算(suàn)。thus, the pump shaft power in addition to the hydraulic power, the friction power increases with medium viscosity and the pressure of work, therefore, when choosing motor medium viscosity is also a very important reference data.especially in transport high viscosity medium, the need for accurate calculation.
    在計算功(gōng)率後(hòu)，選擇配套電機時應遵照(zhào)樣本表格(gé)中所(suǒ)規(guī)定(dìng)的(de)有(yǒu)關規(guī)定。
    n(kw) n≤10 10 < n≤50 n > 50 n > 100 　k 1.5 1.25 1.15 1.1 　nm=n.k 　nm---- 電機功(gōng)率 n---- 軸(zhóu)功率 k---- 功率儲備(bèi)系數
    4. 吸(xī)上(shàng)性能(néng)的計(jì)算(suàn)及(jí)選擇(zé) ：泵(高溫雙(shuāng)螺杆(gǎn)泵,大(dà)流量雙螺(luó)杆泵)工(gōng)作分為以下幾(jǐ)個階段(duàn)： 4. on the absorption performance of calculation and selection: pump (high temperature double screw pump, large flow of double screw pump) work is divided into the following stages:
    4.1 吸入，此(cǐ)時液體連續(xù)不(bú)斷(duàn)地沿(yán)吸入管道(dào)移動；the liquid move continuously along the suction piping;
    4.2 旋轉(zhuǎn)的螺杆把能量(liàng)傳給工作(zuò)液體；rotary screw liquid energy to work;
    4.3 壓出，此時液體帶有(yǒu)克服壓出(chū)管道系統(tǒng)所有阻力(lì)所必需的壓(yā)力從泵(bèng)中排(pái)出。pressure, the liquid with necessary to overcome all delivery pipeline system pressure from the eduction in pump.
    在(zài)以上(shàng)三個階段中，最(zuì)為重要的(de)階段(duàn)是必須保證泵(bèng)的吸上(shàng)條件，泵(bèng)才能(néng)正常(cháng)工作(zuò)，這是泵工(gōng)作的(de)重要(yào)條件(jiàn)，否(fǒu)則(zé)就會發生氣蝕(shí)，即引起振(zhèn)動，噪(zào)音等問題(tí)。 in the above three stages, the most important stage is must ensure that the suction on the condition of the pump, pump can work normally, this is the important condition of pump work, otherwise cavitation occurs, which cause vibration, noise and other issues.
    5. 汽蝕(shí)餘量(liàng)的計算： the calculation of npsh:
    泵(bèng)的汽(qì)蝕餘(yú)量 npshr 與泵的(de)轉速(sù) n ，導程 h 以及泵(bèng)所(suǒ)輸送(sòng)介質(zhì)的(de)粘(zhān)度 v 等(děng)因素(sù)都(dōu)有關系(xì)，對我(wǒ)廠引進的(de) bornemann 雙螺杆泵用以下公(gōng)式(shì)計算： npshr=(1.5+0.253vf 1.84345+0.0572vf 1.55)*v 0.4146 　vf---- 軸(zhóu)向流速(sù)， vf=n*h/60(m/s) ； 　n---- 轉(zhuǎn)速 (r/min) ； 　h---- 導(dǎo)程 (m) ； 　v---- 工(gōng)作粘度 (°e) 。 　由(yóu)此可見，泵(bèng)的 npshr 是(shì)随 vf ， v 的增(zēng)大而增(zēng)大。因(yīn)此在吸入條件(jiàn)不(bú)好的情(qíng)況(kuàng)下，宜選(xuǎn)擇小(xiǎo)導程的雙螺杆(gǎn)泵。這(zhè)在(zài)選(xuǎn)型時(shí)是很重要的。 pump npsh npshr and pump speed n, lead h and the medium viscosity v pump etc have relations, to my factory to introduce bornemann double screw pump with the following formula: npshr = 1.5 (1.5 + 0.253 + 0.0572 0.253 vf vf) * v 0.4146 vf - axial velocity, vf = n * h / 60 (m/s);n - speed (r/min);h - lead (m);v - work viscosity (° e).pump npshr is, therefore, with the vf, v increases.so in the case of suction condition is bad, should choose small lead of double screw pump.this when selection is very important.
    5.1 裝(zhuāng)置汽(qì)蝕餘量 npsha 的(de)計算，這裡不再(zài)闡述。
    5.2 想要保持(chí)泵正常工(gōng)作，即(jí)不發生汽(qì)蝕、振動等(děng)問(wèn)題，必須(xū)保證以(yǐ)下條件(jiàn)： npsha > npshr 這即(jí)是(shì)泵的(de)吸入條件。to keep the normal work of the pump, that is, do not produce the problem such as cavitation, vibration, must ensure that the following conditions: npsha > npshr this is pump suction conditions.
    6. 雙螺杆泵(高溫(wēn)雙螺杆(gǎn)泵,大(dà)流量雙螺(luó)杆泵)的轉(zhuǎn)速選(xuǎn)擇：double screw pump (high temperature double screw pump, large flow of double screw pump) the speed of choice:
    選擇不同的轉速(sù)常(cháng)牽(qiān)涉以(yǐ)下問(wèn)題：choose a different speed often involve the following questions:
    6.1 通(tōng)過選(xuǎn)擇合适的泵轉(zhuǎn)速，以達到适當的性能參(cān)數(shù)如流量等。by selecting the appropriate pump rotation speed, in order to achieve the appropriate performance parameters such as flow rate, etc.
    6.2 随着粘度的不同(tóng)，泵的(de)轉速(sù)亦應(yīng)有所(suǒ)改變。as the viscosity, the speed of the pump should also be changed.
    對于 boremann 雙螺(luó)杆泵，粘(zhān)度的變(biàn)化是(shì)決定轉速(sù)的主要(yào)條(tiáo)件，随着粘度的增大，允許轉速也越(yuè)低。for boremann double screw pump, the change of viscosity is the main condition of ion speed, with the increase of viscosity, allow rotation speed is lower.
    轉(zhuǎn)速的選擇實質也(yě)是(shì)吸上(shàng)性能(néng)的(de)問題，尤其是(shì)在高粘度(dù)的情況下，如果(guǒ)轉速選得過高(gāo)，就會(huì)引起吸入(rù)不足，從而産生噪音(yīn)和振動等問題。因此務必(bì)遵照(zhào)有關原則(zé)選擇(zé)轉速(sù)。speed selection essence is also on the absorption performance problems, especially in the case of high viscosity, if speed selected too high, it will cause insufficient suction, so as to produce the problem such as noise and vibration.so be sure to follow relevant principles to choose speed.
