    ●雙螺杆泵可分為内置軸承和外置軸承兩種形式。在(zài)内置軸承的結構(gòu)型式中軸承由輸送物進行潤滑。外(wài)置軸承結構的雙螺杆泵工(gōng)作腔同軸承是分開的。由于這種泵的結(jié)構和螺杆間存在的側間隙，它可以輸送非(fēi)潤滑性介質。此外，調整同步(bù)齒輪使得螺杆不接(jiē)觸，同時(shí)将輸出扭(niǔ)矩的一半傳給從(cóng)動螺杆。正如所有螺杆泵一(yī)樣，外置軸承式雙螺杆泵也有自吸能力，而且多數泵輸送元件本身都是雙吸對稱(chēng)布置(zhì)，可消除軸向力，也有很(hěn)大的吸高。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.
    ●雙螺杆泵系列産品分為單(dān)吸雙螺杆泵和雙吸雙螺杆泵(bèng)兩大類。該系列産品具有特殊的螺杆型線和與之配套的特殊結構，廣(guǎng)泛适(shì)用于石油、化工、冶金、鋼鐵、電力、船舶、制藥、食品、建材等各種行業，其(qí)适用介質(zhì)之多、輸送範圍之廣、應用工況之複雜是其它泵類産品無法比拟的。這些特點也使得該系列泵具(jù)有潛在的使用發展前(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.
    ●泵體内裝有兩根左、有施單頭螺紋的螺杆，主動螺杆2由動(dòng)力機驅動轉動時，靠同步齒輪1帶動從動螺(luó)杆3轉動。兩根螺杆(gǎn)以及螺杆與泵體. 之間存在着間隙，該間隙靠齒輪和軸承保證。其間隙大小，取決于液體粘度、工作壓力等因(yīn)素。由于每根螺(luó)杆兩端螺紋的旋(xuán)向相反，螺杆轉動時，由螺杆齧合(hé)線形成的泵工作腔。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.
 
 
   ●該型泵(bèng)采(cǎi)用雙吸式結構，螺杆兩端處于同一壓力腔中，軸向力可以自行平衡。兩端軸承(chéng)采用外裝式，單獨(dú)采用潤滑油(脂)潤滑，因而不受輸送介質的(de)影響。兩螺杆間用一對同步齒輪驅(qū)動，螺杆齒面間并不接(jiē)觸(chù)，而留有一微小間隙(xì)，介質中的雜(zá)質并不能對螺杆齒面産生直接的磨損(除沖刷(shuā)外)。 除一些(xiē)小排量泵(bèng)外(2W.W4.0以下)，一(yī)般在泵體上都(dōu)帶有内流式安全(quán)閥，當排放壓力超過額定值時，有一(yī)定的保護作用。 泵體上的進出口方向有兩種，一為水平進，水平(píng)出;二為(wéi)水平進，垂直(zhí)向上出;用戶可根據自(zì)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.

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.

    螺杆泵(高溫雙螺杆泵,大流量雙螺杆泵)在工作(zuò)時，兩(liǎng)螺杆及襯套之間形成密封腔，螺杆每轉動一周便由進口向(xiàng)出口移出一個(gè)密封腔，即一個密(mì)封腔的體積的液體(tǐ)被排出去。理想狀(zhuàng)态下，泵内部無(wú)洩漏，那麼(me)泵的流量與轉速成正比。即： Qth=n*q n---- 轉速； 　q---- 理(lǐ)論排量，即泵每轉一周所排出(chū)的液體體積；　Qth---- 理論排量。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(luó)杆泵(高溫雙螺杆(gǎn)泵,大流量雙螺杆泵)實際工作過程中，其内部存在洩漏(lòu)，也稱滑移量。由(yóu)于泵的密封腔有一定的間隙，且密封腔前、後存在壓(yā)差 △ P ，因此，有一部分液體回流，即存在洩漏，洩漏量用 △ Q 表示，則 Q=Qth- △ Q.顯(xiǎn)而易見，随着密封腔(qiāng)前(qián)、後壓差(chà) △ P 升高，洩漏量 △ Q 逐漸增大。對于不同型線和結構，影響大小也各不相同。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 的影響：試(shì)想：将清(qīng)水和粘稠的(de)漿糊以相同的體積從漏鬥式的容(róng)器中洩漏出去。顯然水比漿糊要洩漏得快。同理，對于雙螺杆泵，粘度大的流體比粘度小的液體的洩漏要小，洩漏量(liàng)與介質(zhì)粘度有一定的比例關系。綜上所述，要綜合地考慮以上各種因素，通過一系列的計算才能精确地知道泵(bèng)的實際流量是否(fǒu)符合工(gōng)況要求。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(yā)力 △ P ：
    與離心泵不同，雙(shuāng)螺杆泵的工作壓力 △ P 由出口負載決定，即出口阻力來決定。出(chū)口阻力與泵的出口處的(de)壓力(lì)是匹配的，出口阻力越大，工作壓力也越大。若想知道壓力，則需要(yào)用(yòng)流體力學的知識對出口阻力精确的計算。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. 軸功率 N ：
    雙螺杆泵(高溫雙螺杆泵,大流量雙螺杆泵)的軸功率(lǜ)分為兩部分，即(jí)： Nth---- 液壓功率，即壓力(lì)液體的(de)能(néng)量； 　Nr---- 摩擦功率(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(yú)确定的壓(yā)力和流(liú)量，其液壓功率是一定的，因此影響軸功率的因素為摩擦率 Nr 。
    摩擦功(gōng)率是由于運(yùn)動部件的摩擦而消耗的那部分(fèn)功率。這些摩擦功(gōng)率(lǜ)顯然是随着工作壓(yā)差的增加而增(zēng)加的(de)，并且介(jiè)質粘(zhān)度的增(zēng)加也會引(yǐn)起液體摩擦功率的增加。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，泵的軸功率除(chú)了液(yè)壓功率外，其中摩擦功率随介質粘度及(jí)工作壓力而增加，因此在選擇配套電機時，介質的粘度也是(shì)一個非常重要的參(cān)考數(shù)據。尤其在輸送高粘度介(jiè)質時，需要作比較精确的計算。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.
    在計算功(gōng)率後，選擇配套電(diàn)機時應遵照樣本(běn)表格中所規定的有關規定。
    N(KW) N≤10 10 < N≤50 N > 50 N > 100 　K 1.5 1.25 1.15 1.1 　Nm=N.K 　Nm---- 電機功率 N---- 軸功率 K---- 功率儲備(bèi)系(xì)數
    4. 吸上性能的計算及選擇(zé) ：泵(高溫雙(shuāng)螺杆泵,大流量(liàng)雙螺(luó)杆泵)工作分(fèn)為(wéi)以下幾個階段： 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，此時液體連續不斷地沿(yán)吸入(rù)管道移動；the liquid move continuously along the suction piping;
    4.2 旋轉的(de)螺杆把能量傳給工作液體；rotary screw liquid energy to work;
    4.3 壓出，此時液體帶有克服壓出管道系統所有阻力所必需的壓力從泵(bèng)中排出(chū)。pressure, the liquid with necessary to overcome all delivery pipeline system pressure from the eduction in pump.
    在以上(shàng)三(sān)個階(jiē)段中，最(zuì)為重要的階段是必須保證泵的吸上條件，泵才能(néng)正常工(gōng)作，這是(shì)泵工作的(de)重要條件，否則(zé)就會發生(shēng)氣蝕，即引(yǐn)起振動，噪音等(děng)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)餘量的計算： The calculation of NPSH:
    泵(bèng)的(de)汽(qì)蝕餘量 NPSHr 與(yǔ)泵的(de)轉速 n ，導程 h 以及泵(bèng)所輸送介質的粘度 v 等因素都有關系，對我廠引進的 Bornemann 雙螺杆泵用以下公式計算： NPSHr=(1.5+0.253VF 1.84345+0.0572VF 1.55)*v 0.4146 　VF---- 軸向流速， VF=n*h/60(m/s) ； 　n---- 轉速 (r/min) ； 　h---- 導程 (m) ； 　v---- 工(gōng)作粘度 (°E) 。 　由此可見，泵的 NPSHr 是随 VF ， v 的增大而增(zēng)大。因此在吸入(rù)條件(jiàn)不好的情況(kuàng)下，宜選擇小導程的雙螺杆(gǎn)泵。這在選(xuǎn)型時是很(hěn)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 裝置汽(qì)蝕餘量 NPSHa 的計算，這裡不(bú)再闡述。
    5.2 想要保持泵正(zhèng)常工作，即(jí)不發生汽蝕、振動等問(wèn)題，必須保證以下條件： NPSHa > NPSHr 這即是泵的吸入條件。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(高溫雙(shuāng)螺杆泵,大流量雙螺杆泵)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:
    選擇不同的轉速常牽涉以下問題：Choose a different speed often involve the following questions:
    6.1 通過選擇合(hé)适的泵轉(zhuǎn)速，以達到适當(dāng)的性能參數如流量等。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(de)不同，泵的轉速亦(yì)應有所改變(biàn)。as the viscosity, the speed of the pump should also be changed.
    對于 Boremann 雙螺杆泵，粘度的變化是決定轉速的主要條件，随着粘度的增大，允許轉速也越低。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.
    轉速的選擇實質也是吸(xī)上性能的問題，尤其是在高粘度(dù)的情況下(xià)，如果轉(zhuǎn)速選得過高，就會引起吸入(rù)不足，從而産生噪音和振動等問題。因此(cǐ)務必(bì)遵照有關原則選擇轉速。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.
