    ●雙螺杆(gǎn)泵可分為内置(zhì)軸承和外置軸(zhou)承兩種形式。在(zài)内置軸承的結(jie)構型式中軸承(chéng)由輸送物進行(háng)潤滑。外置軸承(chéng)結構的雙螺杆(gan)泵工作腔同軸(zhóu)承是分開的。由(you)于這種泵的結(jie)構和螺杆間存(cun)在的側間隙，它(ta)可以輸送非潤(run)滑性介質。此外(wài)，調整同步齒輪(lún)使得螺杆不接(jiē)觸，同時将輸出(chu)扭矩的一半傳(chuan)給從動螺杆。正(zhèng)如所有螺杆泵(beng)一樣，外置軸承(chéng)式雙螺杆泵也(ye)有自吸能力，而(er)且多數泵輸送(song)元件本身都是(shi)雙吸對稱布置(zhì)，可消除軸向力(lì)，也有很大的吸(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.
    ●雙螺杆泵系(xì)列産品分為單(dan)吸雙螺杆泵和(hé)雙吸雙螺杆泵(beng)兩大類。該系列(lie)産品具有特殊(shu)的螺杆型線和(he)與之配套的特(tè)殊結構，廣泛适(shi)用于石油、化工(gōng)、冶金、鋼鐵、電力(lì)、船舶、制藥、食品(pin)、建材等各種行(hang)業，其适用介質(zhì)之多、輸送範圍(wéi)之廣、應用工況(kuàng)之複雜是其它(tā)泵類産品無法(fa)比拟的。這些特(tè)點也使得該系(xi)列泵具有潛在(zai)的使用發展前(qian)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(yǒu)兩根左、有施單(dān)頭螺紋的螺杆(gan)，主動螺杆2由動(dong)力機驅動轉動(dong)時，靠同步齒輪(lun)1帶動從動螺杆(gan)3轉動。兩根螺杆(gǎn)以及螺杆與泵(bèng)體. 之間存在着(zhe)間隙，該間隙靠(kào)齒輪和軸承保(bǎo)證。其間隙大小(xiao)，取決于液體粘(zhan)度、工作壓力等(deng)因素。由于每根(gen)螺杆兩端螺紋(wén)的旋向相反，螺(luó)杆轉動時，由螺(luo)杆齧合線形成(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)型泵采用雙吸(xi)式結構，螺杆兩(liang)端處于同一壓(yā)力腔中，軸向力(lì)可以自行平衡(heng)。兩端軸承采用(yòng)外裝式，單獨采(cai)用潤滑油(脂)潤(rùn)滑，因而不受輸(shū)送介質的影響(xiǎng)。兩螺杆間用一(yī)對同步齒輪驅(qu)動，螺杆齒面間(jian)并不接觸，而留(liú)有一微小間隙(xì)，介質中的雜質(zhi)并不能對螺杆(gǎn)齒面産生直接(jiē)的磨損(除沖刷(shuā)外)。 除一些小排(pái)量泵外(2W.W4.0以下)，一(yi)般在泵體上都(dōu)帶有内流式安(an)全閥，當排放壓(ya)力超過額定值(zhí)時，有一定的保(bǎo)護作用。 泵體上(shang)的進出口方向(xiàng)有兩種，一為水(shui)平進，水平出;二(er)為水平進，垂直(zhi)向上出;用戶可(ke)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.
 
 
  
   ●性能參數(shù)的選擇：
    1. 流量 Q ：
    作(zuo)為容積式泵，影(yǐng)響雙螺杆泵流(liú)量的因素主要(yao)有轉速 n ，壓力 p ，以(yǐ)及介質的粘度(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.
    1.1 轉速 n 的影響：
    1.2 壓力 △ P 的(de)影響：
    雙螺杆泵(bèng)(高溫雙螺杆泵(beng),大流量雙螺杆(gǎn)泵)實際工作過(guo)程中，其内部存(cún)在洩漏，也稱滑(huá)移量。由于泵的(de)密封腔有一定(ding)的間隙，且密封(feng)腔前、後存在壓(yā)差 △ P ，因此，有一部(bu)分液體回流，即(jí)存在洩漏，洩漏(lou)量用 △ Q 表示，則 Q=Qth- △ Q.顯(xian)而易見，随着密(mì)封腔前、後壓差(cha) △ P 升高，洩漏量 △ Q 逐(zhu)漸增大。對于不(bu)同型線和結構(gòu)，影響大小也各(ge)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(de)影響：試想：将清(qīng)水和粘稠的漿(jiāng)糊以相同的體(tǐ)積從漏鬥式的(de)容器中洩漏出(chū)去。顯然水比漿(jiāng)糊要洩漏得快(kuài)。同理，對于雙螺(luo)杆泵，粘度大的(de)流體比粘度小(xiao)的液體的洩漏(lou)要小，洩漏量與(yǔ)介質粘度有一(yi)定的比例關系(xi)。綜上所述，要綜(zōng)合地考慮以上(shàng)各種因素，通過(guo)一系列的計算(suàn)才能精确地知(zhi)道泵的實際流(liu)量是否符合工(gong)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. 壓力 △ P ：
    與(yu)離心泵不同，雙(shuang)螺杆泵的工作(zuo)壓力 △ P 由出口負(fù)載決定，即出口(kou)阻力來決定。出(chū)口阻力與泵的(de)出口處的壓力(lì)是匹配的，出口(kǒu)阻力越大，工作(zuò)壓力也越大。若(ruò)想知道壓力，則(zé)需要用流體力(lì)學的知識對出(chū)口阻力精确的(de)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(shuāng)螺杆泵(高溫雙(shuāng)螺杆泵,大流量(liàng)雙螺杆泵)的軸(zhou)功率分為兩部(bu)分，即： Nth---- 液壓功率(lü)，即壓力液體的(de)能量； 　Nr---- 摩擦功率(lü)。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.
    對于确定的壓(ya)力和流量，其液(yè)壓功率是一定(dìng)的，因此影響軸(zhou)功率的因素為(wéi)摩擦率 Nr 。
    摩擦功(gōng)率是由于運動(dong)部件的摩擦而(ér)消耗的那部分(fèn)功率。這些摩擦(cā)功率顯然是随(suí)着工作壓差的(de)增加而增加的(de)，并且介質粘度(dù)的增加也會引(yǐn)起液體摩擦功(gong)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(cǐ)，泵的軸功率除(chu)了液壓功率外(wài)，其中摩擦功率(lü)随介質粘度及(ji)工作壓力而增(zēng)加，因此在選擇(zé)配套電機時，介(jiè)質的粘度也是(shì)一個非常重要(yào)的參考數據。尤(yóu)其在輸送高粘(zhān)度介質時，需要(yào)作比較精确的(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.
    在計算功(gong)率後，選擇配套(tào)電機時應遵照(zhào)樣本表格中所(suǒ)規定的有關規(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---- 電機功率 N---- 軸(zhóu)功率 K---- 功率儲備(bei)系數
    4. 吸上性能(néng)的計算及選擇(ze) ：泵(高溫雙螺杆(gǎn)泵,大流量雙螺(luó)杆泵)工作分為(wéi)以下幾個階段(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，此時液體(tǐ)連續不斷地沿(yán)吸入管道移動(dong)；the liquid move continuously along the suction piping;
    4.2 旋轉的螺杆把(ba)能量傳給工作(zuò)液體；rotary screw liquid energy to work;
    4.3 壓出，此時(shí)液體帶有克服(fu)壓出管道系統(tong)所有阻力所必(bì)需的壓力從泵(beng)中排出。pressure, the liquid with necessary to overcome all delivery pipeline system pressure from the eduction in pump.
    在以上(shang)三個階段中，最(zui)為重要的階段(duan)是必須保證泵(bèng)的吸上條件，泵(beng)才能正常工作(zuò)，這是泵工作的(de)重要條件，否則(zé)就會發生氣蝕(shi)，即引起振動，噪(zao)音等問題。 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(shi)餘量的計算： The calculation of NPSH:
    泵(bèng)的汽蝕餘量 NPSHr 與(yǔ)泵的轉速 n ，導程(cheng) h 以及泵所輸送(sòng)介質的粘度 v 等(deng)因素都有關系(xì)，對我廠引進的(de) Bornemann 雙螺杆泵用以(yǐ)下公式計算： NPSHr=(1.5+0.253VF 1.84345+0.0572VF 1.55)*v 0.4146 　VF---- 軸(zhóu)向流速， VF=n*h/60(m/s) ； 　n---- 轉速 (r/min) ； 　h---- 導(dao)程 (m) ； 　v---- 工作粘度 (°E) 。 　由(you)此可見，泵的 NPSHr 是(shi)随 VF ， v 的增大而增(zēng)大。因此在吸入(ru)條件不好的情(qíng)況下，宜選擇小(xiao)導程的雙螺杆(gǎn)泵。這在選型時(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)泵正常工作，即(jí)不發生汽蝕、振(zhen)動等問題，必須(xu)保證以下條件(jian)： NPSHa > NPSHr 這即是泵的吸(xi)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(gan)泵(高溫雙螺杆(gan)泵,大流量雙螺(luo)杆泵)的轉速選(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(de)轉速常牽涉以(yǐ)下問題：Choose a different speed often involve the following questions:
    6.1 通過選(xuǎn)擇合适的泵轉(zhuan)速，以達到适當(dāng)的性能參數如(ru)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(zhān)度的不同，泵的(de)轉速亦應有所(suo)改變。as the viscosity, the speed of the pump should also be changed.
    對于 Boremann 雙螺(luo)杆泵，粘度的變(bian)化是決定轉速(su)的主要條件，随(sui)着粘度的增大(dà)，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.
    轉速的選擇(zé)實質也是吸上(shang)性能的問題，尤(you)其是在高粘度(du)的情況下，如果(guo)轉速選得過高(gāo)，就會引起吸入(ru)不足，從而産生(sheng)噪音和振動等(děng)問題。因此務必(bì)遵照有關原則(ze)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.
