●雙螺杆(gan)泵可分(fen)為内置(zhi)軸承和(hé)外置軸(zhóu)承兩種(zhong)形式。在(zài)内置軸(zhou)承的結(jié)構型式(shi)中軸承(chéng)由輸送(song)物進行(háng)潤滑。外(wai)置軸承(cheng)結構的(de)雙螺杆(gǎn)泵工作(zuo)腔同軸(zhóu)承是分(fen)開的。由(you)于這種(zhǒng)泵的結(jié)構和螺(luó)杆間存(cún)在的側(cè)間隙，它(ta)可以輸(shu)送非潤(run)滑性介(jiè)質。此外(wài)，調整同(tong)步齒輪(lun)使得螺(luó)杆不接(jiē)觸，同時(shi)将輸出(chū)扭矩的(de)一半傳(chuán)給從動(dong)螺杆。正(zheng)如所有(you)螺杆泵(bèng)一樣，外(wai)置軸承(chéng)式雙螺(luo)杆泵也(ye)有自吸(xi)能力，而(er)且多數(shu)泵輸送(song)元件本(běn)身都是(shì)雙吸對(dui)稱布置(zhì)，可消除(chu)軸向力(lì)，也有很(hen)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.

●雙螺(luo)杆泵系(xi)列産品(pǐn)分為單(dān)吸雙螺(luo)杆泵和(hé)雙吸雙(shuang)螺杆泵(bèng)兩大類(lei)。該系列(lie)産品具(ju)有特殊(shū)的螺杆(gǎn)型線和(hé)與之配(pèi)套的特(te)殊結構(gòu)，廣泛适(shì)用于石(shi)油、化工(gōng)、冶金、鋼(gang)鐵、電力(lì)、船舶、制(zhi)藥、食品(pin)、建材等(děng)各種行(hang)業，其适(shì)用介質(zhì)之多、輸(shu)送範圍(wei)之廣、應(yīng)用工況(kuàng)之複雜(za)是其它(tā)泵類産(chǎn)品無法(fǎ)比拟的(de)。這些特(te)點也使(shi)得該系(xi)列泵具(jù)有潛在(zai)的使用(yong)發展前(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.

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.

●性(xìng)能參數(shù)的選擇(zé)：

1. 流量 Q ：

作(zuò)為容積(ji)式泵，影(ying)響雙螺(luo)杆泵流(liú)量的因(yin)素主要(yao)有轉速(su) n ，壓力 p ，以(yǐ)及介質(zhi)的粘度(dù) 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.

轉速 n 的(de)影響：

螺(luo)杆泵(高(gāo)溫雙螺(luo)杆泵,大(dà)流量雙(shuāng)螺杆泵(bèng))在工作(zuo)時，兩螺(luó)杆及襯(chen)套之間(jiān)形成密(mì)封腔，螺(luó)杆每轉(zhuan)動一周(zhou)便由進(jin)口向出(chū)口移出(chu)一個密(mi)封腔，即(ji)一個密(mì)封腔的(de)體積的(de)液體被(bei)排出去(qù)。理想狀(zhuang)态下，泵(beng)内部無(wú)洩漏，那(nà)麼泵的(de)流量與(yǔ)轉速成(chéng)正比。即(ji)： Qth=n*q n---- 轉速；　q---- 理(lǐ)論排量(liàng)，即泵每(mei)轉一周(zhou)所排出(chū)的液體(tǐ)體積；　Qth---- 理(lǐ)論排量(liang)。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(shuāng)螺杆泵(beng)(高溫雙(shuāng)螺杆泵(bèng),大流量(liang)雙螺杆(gǎn)泵)實際(ji)工作過(guò)程中，其(qi)内部存(cún)在洩漏(lou)，也稱滑(hua)移量。由(you)于泵的(de)密封腔(qiāng)有一定(dìng)的間隙(xi)，且密封(feng)腔前、後(hou)存在壓(ya)差 △ P ，因此(ci)，有一部(bù)分液體(tǐ)回流，即(ji)存在洩(xiè)漏，洩漏(lou)量用 △ Q 表(biao)示，則 Q=Qth- △ Q.顯(xian)而易見(jiàn)，随着密(mi)封腔前(qian)、後壓差(chà) △ P 升高，洩(xiè)漏量 △ Q 逐(zhu)漸增大(da)。對于不(bú)同型線(xiàn)和結構(gou)，影響大(dà)小也各(gè)不相同(tong)。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(qīng)水和粘(zhan)稠的漿(jiang)糊以相(xiang)同的體(ti)積從漏(lou)鬥式的(de)容器中(zhōng)洩漏出(chū)去。顯然(ran)水比漿(jiāng)糊要洩(xiè)漏得快(kuài)。同理，對(dui)于雙螺(luó)杆泵，粘(zhān)度大的(de)流體比(bi)粘度小(xiǎo)的液體(tǐ)的洩漏(lòu)要小，洩(xiè)漏量與(yǔ)介質粘(zhan)度有一(yī)定的比(bǐ)例關系(xì)。綜上所(suo)述，要綜(zong)合地考(kǎo)慮以上(shàng)各種因(yīn)素，通過(guò)一系列(liè)的計算(suan)才能精(jīng)确地知(zhī)道泵的(de)實際流(liu)量是否(fǒu)符合工(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 ：

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(zhóu)功率 N ：

雙(shuang)螺杆泵(bèng)(高溫雙(shuāng)螺杆泵(beng),大流量(liang)雙螺杆(gan)泵)的軸(zhou)功率分(fen)為兩部(bù)分，即： Nth---- 液(ye)壓功率(lü)，即壓力(lì)液體的(de)能量；　Nr---- 摩(mo)擦功率(lǜ)。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(que)定的壓(yā)力和流(liú)量，其液(yè)壓功率(lü)是一定(ding)的，因此(cǐ)影響軸(zhóu)功率的(de)因素為(wéi)摩擦率(lǜ)

摩擦功(gong)率是由(you)于運動(dong)部件的(de)摩擦而(ér)消耗的(de)那部分(fen)功率。這(zhe)些摩擦(ca)功率顯(xian)然是随(suí)着工作(zuo)壓差的(de)增加而(ér)增加的(de)，并且介(jiè)質粘度(du)的增加(jia)也會引(yin)起液體(ti)摩擦功(gong)率的增(zeng)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(chu)了液壓(ya)功率外(wai)，其中摩(mo)擦功率(lü)随介質(zhì)粘度及(ji)工作壓(yā)力而增(zēng)加，因此(ci)在選擇(ze)配套電(diàn)機時，介(jie)質的粘(zhān)度也是(shì)一個非(fēi)常重要(yào)的參考(kǎo)數據。尤(you)其在輸(shū)送高粘(zhan)度介質(zhì)時，需要(yào)作比較(jiào)精确的(de)計算。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(zai)計算功(gōng)率後，選(xuǎn)擇配套(tao)電機時(shí)應遵照(zhao)樣本表(biao)格中所(suo)規定的(de)有關規(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(ji)功率 N---- 軸(zhou)功率 K---- 功(gong)率儲備(bèi)系數

4. 吸(xi)上性能(neng)的計算(suàn)及選擇(ze) ：泵(高溫(wen)雙螺杆(gǎn)泵,大流(liú)量雙螺(luo)杆泵)工(gōng)作分為(wei)以下幾(ji)個階段(duan)： 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(ti)連續不(bú)斷地沿(yán)吸入管(guan)道移動(dong)；

4.3 壓(yā)出，此時(shi)液體帶(dài)有克服(fú)壓出管(guan)道系統(tong)所有阻(zu)力所必(bì)需的壓(ya)力從泵(bèng)中排出(chu)。

在以上(shang)三個階(jie)段中，最(zui)為重要(yao)的階段(duan)是必須(xū)保證泵(bèng)的吸上(shang)條件，泵(beng)才能正(zhèng)常工作(zuò)，這是泵(beng)工作的(de)重要條(tiáo)件，否則(ze)就會發(fā)生氣蝕(shí)，即引起(qi)振動，噪(zao)音等問(wèn)題。 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)餘量的(de)計算： The calculation of NPSH:

泵(bèng)的汽蝕(shí)餘量 NPSHr 與(yǔ)泵的轉(zhuǎn)速 n ，導程(cheng) h 以及泵(bèng)所輸送(sòng)介質的(de)粘度 v 等(deng)因素都(dou)有關系(xi)，對我廠(chang)引進的(de) Bornemann 雙螺杆(gan)泵用以(yǐ)下公式(shi)計算： NPSHr=(1.5+0.253VF 1.84345+0.0572VF 1.55)*v 0.4146 　VF---- 軸(zhou)向流速(su)， VF=n*h/60(m/s) ；　n---- 轉速 (r/min) ；　h---- 導(dao)程 (m) ；　v---- 工作(zuò)粘度 (°E) 。　由(yóu)此可見(jian)，泵的 NPSHr 是(shi)随 VF ， v 的增(zēng)大而增(zeng)大。因此(cǐ)在吸入(rù)條件不(bú)好的情(qíng)況下，宜(yí)選擇小(xiǎo)導程的(de)雙螺杆(gan)泵。這在(zai)選型時(shí)是很重(zhòng)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.

6. 雙螺杆(gan)泵(高溫(wen)雙螺杆(gǎn)泵,大流(liu)量雙螺(luo)杆泵)的(de)轉速選(xuǎn)擇：Double screw pump (high temperature double screw pump, large flow of double screw pump) the speed of choice:

選擇(ze)不同的(de)轉速常(cháng)牽涉以(yi)下問題(tí)：Choose a different speed often involve the following questions:

6.1 通過選(xuǎn)擇合适(shì)的泵轉(zhuan)速，以達(da)到适當(dang)的性能(neng)參數如(ru)流量等(deng)。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(zhan)度的不(bú)同，泵的(de)轉速亦(yì)應有所(suǒ)改變。as the viscosity, the speed of the pump should also be changed.

對(duì)于 Boremann 雙螺(luó)杆泵，粘(zhān)度的變(biàn)化是決(jué)定轉速(su)的主要(yao)條件，随(sui)着粘度(dù)的增大(dà)，允許轉(zhuǎn)速也越(yue)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.

轉速(su)的選擇(ze)實質也(yě)是吸上(shàng)性能的(de)問題，尤(yóu)其是在(zài)高粘度(dù)的情況(kuàng)下，如果(guo)轉速選(xuǎn)得過高(gao)，就會引(yin)起吸入(rù)不足，從(cóng)而産生(sheng)噪音和(hé)振動等(deng)問題。因(yīn)此務必(bì)遵照有(you)關原則(zé)選擇轉(zhuǎn)速。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.
