    ●雙螺(luo)杆泵可分為(wéi)内置軸承和(hé)外置軸承兩(liǎng)種形式。在内(nei)置軸承的結(jié)構型式中軸(zhóu)承由輸送物(wù)進行潤滑。外(wai)置軸承結構(gou)的雙螺杆泵(bèng)工作腔同軸(zhou)承是分開的(de)。由于這種泵(beng)的結構和螺(luó)杆間存在的(de)側間隙，它可(ke)以輸送非潤(rùn)滑性介質。此(cǐ)外，調整同步(bu)齒輪使得螺(luo)杆不接觸，同(tong)時将輸出扭(niu)矩的一半傳(chuan)給從動螺杆(gǎn)。正如所有螺(luó)杆泵一樣，外(wai)置軸承式雙(shuang)螺杆泵也有(you)自吸能力，而(er)且多數泵輸(shū)送元件本身(shēn)都是雙吸對(dui)稱布置，可消(xiāo)除軸向力，也(ye)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(bèng)系列産品分(fen)為單吸雙螺(luo)杆泵和雙吸(xī)雙螺杆泵兩(liang)大類。該系列(lie)産品具有特(te)殊的螺杆型(xíng)線和與之配(pei)套的特殊結(jie)構，廣泛适用(yòng)于石油、化工(gōng)、冶金、鋼鐵、電(dian)力、船舶、制藥(yao)、食品、建材等(děng)各種行業，其(qi)适用介質之(zhi)多、輸送範圍(wéi)之廣、應用工(gong)況之複雜是(shi)其它泵類産(chǎn)品無法比拟(nǐ)的。這些特點(diǎn)也使得該系(xi)列泵具有潛(qian)在的使用發(fa)展前景。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(ti)内裝有兩根(gen)左、有施單頭(tóu)螺紋的螺杆(gǎn)，主動螺杆2由(yóu)動力機驅動(dong)轉動時，靠同(tóng)步齒輪1帶動(dòng)從動螺杆3轉(zhuan)動。兩根螺杆(gan)以及螺杆與(yu)泵體. 之間存(cun)在着間隙，該(gai)間隙靠齒輪(lun)和軸承保證(zheng)。其間隙大小(xiao)，取決于液體(tǐ)粘度、工作壓(ya)力等因素。由(you)于每根螺杆(gan)兩端螺紋的(de)旋向相反，螺(luó)杆轉動時，由(you)螺杆齧合線(xiàn)形成的泵工(gong)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(beng)采用雙吸式(shì)結構，螺杆兩(liang)端處于同一(yi)壓力腔中，軸(zhou)向力可以自(zi)行平衡。兩端(duan)軸承采用外(wai)裝式，單獨采(cai)用潤滑油(脂(zhi))潤滑，因而不(bú)受輸送介質(zhi)的影響。兩螺(luo)杆間用一對(dui)同步齒輪驅(qū)動，螺杆齒面(mian)間并不接觸(chu)，而留有一微(wēi)小間隙，介質(zhi)中的雜質并(bìng)不能對螺杆(gan)齒面産生直(zhí)接的磨損(除(chu)沖刷外)。 除一(yī)些小排量泵(beng)外(2W.W4.0以下)，一般(ban)在泵體上都(dōu)帶有内流式(shì)安全閥，當排(pai)放壓力超過(guò)額定值時，有(yǒu)一定的保護(hù)作用。 泵體上(shang)的進出口方(fang)向有兩種，一(yī)為水平進，水(shui)平出;二為水(shui)平進，垂直向(xiang)上出;用戶可(ke)根據自己需(xū)要選擇。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(neng)參數的選擇(zé)：
    1. 流量 Q ：
    作為容(róng)積式泵，影響(xiǎng)雙螺杆泵流(liu)量的因素主(zhǔ)要有轉速 n ，壓(yā)力 p ，以及介質(zhi)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：
    螺杆(gan)泵(高溫雙螺(luó)杆泵,大流量(liang)雙螺杆泵)在(zài)工作時，兩螺(luó)杆及襯套之(zhī)間形成密封(feng)腔，螺杆每轉(zhuǎn)動一周便由(yóu)進口向出口(kou)移出一個密(mi)封腔，即一個(ge)密封腔的體(ti)積的液體被(bèi)排出去。理想(xiang)狀态下，泵内(nèi)部無洩漏，那(na)麼泵的流量(liàng)與轉速成正(zhèng)比。即： Qth=n*q n---- 轉速； 　q---- 理(lǐ)論排量，即泵(beng)每轉一周所(suo)排出的液體(tǐ)體積；　Qth---- 理論排(pai)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 的影(ying)響：
    雙螺杆泵(beng)(高溫雙螺杆(gǎn)泵,大流量雙(shuang)螺杆泵)實際(ji)工作過程中(zhōng)，其内部存在(zai)洩漏，也稱滑(huá)移量。由于泵(beng)的密封腔有(yǒu)一定的間隙(xì)，且密封腔前(qián)、後存在壓差(cha) △ P ，因此，有一部(bu)分液體回流(liú)，即存在洩漏(lòu)，洩漏量用 △ Q 表(biǎo)示，則 Q=Qth- △ Q.顯而易(yi)見，随着密封(fēng)腔前、後壓差(chà) △ P 升高，洩漏量(liang) △ Q 逐漸增大。對(dui)于不同型線(xian)和結構，影響(xiang)大小也各不(bú)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(jiang)清水和粘稠(chou)的漿糊以相(xiàng)同的體積從(cong)漏鬥式的容(rong)器中洩漏出(chū)去。顯然水比(bi)漿糊要洩漏(lòu)得快。同理，對(dui)于雙螺杆泵(bèng)，粘度大的流(liú)體比粘度小(xiao)的液體的洩(xiè)漏要小，洩漏(lòu)量與介質粘(zhan)度有一定的(de)比例關系。綜(zōng)上所述，要綜(zong)合地考慮以(yi)上各種因素(su)，通過一系列(liè)的計算才能(néng)精确地知道(dào)泵的實際流(liu)量是否符合(he)工況要求。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(beng)不同，雙螺杆(gan)泵的工作壓(yā)力 △ P 由出口負(fù)載決定，即出(chū)口阻力來決(jué)定。出口阻力(li)與泵的出口(kou)處的壓力是(shì)匹配的，出口(kou)阻力越大，工(gong)作壓力也越(yuè)大。若想知道(dao)壓力，則需要(yào)用流體力學(xué)的知識對出(chu)口阻力精确(que)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(gōng)率 N ：
    雙螺杆泵(beng)(高溫雙螺杆(gan)泵,大流量雙(shuāng)螺杆泵)的軸(zhóu)功率分為兩(liang)部分，即： Nth---- 液壓(ya)功率，即壓力(lì)液體的能量(liang)； 　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(dui)于确定的壓(yā)力和流量，其(qí)液壓功率是(shi)一定的，因此(cǐ)影響軸功率(lü)的因素為摩(mó)擦率 Nr 。
    摩擦功(gong)率是由于運(yùn)動部件的摩(mo)擦而消耗的(de)那部分功率(lü)。這些摩擦功(gong)率顯然是随(sui)着工作壓差(chà)的增加而增(zēng)加的，并且介(jie)質粘度的增(zēng)加也會引起(qi)液體摩擦功(gōng)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(yóu)此，泵的軸功(gong)率除了液壓(ya)功率外，其中(zhōng)摩擦功率随(suí)介質粘度及(ji)工作壓力而(ér)增加，因此在(zai)選擇配套電(diàn)機時，介質的(de)粘度也是一(yī)個非常重要(yao)的參考數據(jù)。尤其在輸送(song)高粘度介質(zhi)時，需要作比(bi)較精确的計(ji)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(pei)套電機時應(yīng)遵照樣本表(biǎo)格中所規定(dìng)的有關規定(ding)。
    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(chu)備系數
    4. 吸上(shang)性能的計算(suàn)及選擇 ：泵(高(gao)溫雙螺杆泵(beng),大流量雙螺(luo)杆泵)工作分(fen)為以下幾個(ge)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(cǐ)時液體連續(xù)不斷地沿吸(xi)入管道移動(dong)；the liquid move continuously along the suction piping;
    4.2 旋轉的螺杆(gǎn)把能量傳給(gěi)工作液體；rotary screw liquid energy to work;
    4.3 壓(ya)出，此時液體(tǐ)帶有克服壓(yā)出管道系統(tong)所有阻力所(suo)必需的壓力(li)從泵中排出(chū)。pressure, the liquid with necessary to overcome all delivery pipeline system pressure from the eduction in pump.
    在以上三個(gè)階段中，最為(wei)重要的階段(duan)是必須保證(zhèng)泵的吸上條(tiao)件，泵才能正(zhèng)常工作，這是(shì)泵工作的重(zhòng)要條件，否則(ze)就會發生氣(qi)蝕，即引起振(zhèn)動，噪音等問(wen)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. 汽蝕餘量(liang)的計算： The calculation of NPSH:
    泵的(de)汽蝕餘量 NPSHr 與(yu)泵的轉速 n ，導(dǎo)程 h 以及泵所(suǒ)輸送介質的(de)粘度 v 等因素(su)都有關系，對(dui)我廠引進的(de) Bornemann 雙螺杆泵用(yong)以下公式計(jì)算： NPSHr=(1.5+0.253VF 1.84345+0.0572VF 1.55)*v 0.4146 　VF---- 軸向流速(sù)， VF=n*h/60(m/s) ； 　n---- 轉速 (r/min) ； 　h---- 導程 (m) ； 　v---- 工(gōng)作粘度 (°E) 。 　由此(ci)可見，泵的 NPSHr 是(shì)随 VF ， v 的增大而(er)增大。因此在(zai)吸入條件不(bu)好的情況下(xià)，宜選擇小導(dao)程的雙螺杆(gǎn)泵。這在選型(xing)時是很重要(yao)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 裝置汽蝕(shí)餘量 NPSHa 的計算(suan)，這裡不再闡(chan)述。
    5.2 想要保持(chí)泵正常工作(zuo)，即不發生汽(qi)蝕、振動等問(wen)題，必須保證(zhèng)以下條件： NPSHa > NPSHr 這(zhe)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(luo)杆泵(高溫雙(shuāng)螺杆泵,大流(liu)量雙螺杆泵(beng))的轉速選擇(ze)：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(she)以下問題：Choose a different speed often involve the following questions:
    6.1 通(tōng)過選擇合适(shì)的泵轉速，以(yǐ)達到适當的(de)性能參數如(rú)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(zhe)粘度的不同(tóng)，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(gǎn)泵，粘度的變(biàn)化是決定轉(zhuǎn)速的主要條(tiáo)件，随着粘度(du)的增大，允許(xu)轉速也越低(di)。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(ze)實質也是吸(xī)上性能的問(wen)題，尤其是在(zài)高粘度的情(qing)況下，如果轉(zhuan)速選得過高(gāo)，就會引起吸(xī)入不足，從而(er)産生噪音和(he)振動等問題(ti)。因此務必遵(zūn)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.
