●雙螺杆泵可(Ke)分為[Wei]内置軸承和外置軸[Zhou]承兩種形式。在(Zai)内置軸承的結構型[Xing]式中軸承由輸送物進行潤滑[Hua]。外(Wai)置軸承[Cheng]結構的雙螺杆[Gan]泵工作腔同軸[Zhou]承是分開的。由于這種(Zhong)泵的結構和螺杆間存在的側間隙，它可以輸送非潤滑性介質(Zhi)。此外，調整同步齒輪[Lun]使得[De]螺杆不接[Jie]觸，同時将輸出(Chu)扭矩的一半傳給從動螺杆。正如所有(You)螺杆泵一樣，外置(Zhi)軸承式雙螺杆泵[Beng]也(Ye)有自吸能力，而[Er]且多數泵輸送元件本(Ben)身都是雙吸[Xi]對稱布置(Zhi)，可消除軸向力，也有很大(Da)的(De)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[Dan]吸雙螺杆泵和(He)雙[Shuang]吸[Xi]雙螺杆泵(Beng)兩大類。該系(Xi)列産品具[Ju]有特殊[Shu]的螺杆(Gan)型線和與之(Zhi)配套的特殊結構，廣[Guang]泛适(Shi)用于石油、化[Hua]工、冶金、鋼鐵[Tie]、電力(Li)、船舶、制藥、食品[Pin]、建材等各[Ge]種行業，其适用(Yong)介質(Zhi)之多、輸送範[Fan]圍之廣、應用工況之複雜是[Shi]其它(Ta)泵類産品無法比拟的。這些特點也使[Shi]得該[Gai]系[Xi]列泵具有[You]潛在的使用發展(Zhan)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[You]兩[Liang]根左、有施單頭螺紋的螺杆，主動螺杆[Gan]2由動(Dong)力機驅[Qu]動轉動時，靠同步齒輪(Lun)1帶動從動螺杆3轉動。兩根螺杆[Gan]以及螺杆[Gan]與泵[Beng]體. 之間存在着間隙(Xi)，該間隙靠齒輪和(He)軸承保[Bao]證。其間隙大小，取決于液體粘度、工作壓力等[Deng]因素(Su)。由于每根螺杆兩端螺紋[Wen]的旋向相反(Fan)，螺杆轉動時，由螺杆齧合線形成的泵[Beng]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(Xing)泵(Beng)采用雙吸(Xi)式結構，螺杆[Gan]兩端處于同一壓[Ya]力腔中[Zhong]，軸向力可以自行平衡。兩端軸承采用外裝式，單獨采[Cai]用潤滑油(脂)潤滑，因(Yin)而不受輸送介(Jie)質的[De]影響。兩螺(Luo)杆間用一(Yi)對同步齒輪[Lun]驅動，螺(Luo)杆齒面間并不接觸[Chu]，而留有一微小間隙，介質中的雜質并不能對螺[Luo]杆齒面産生(Sheng)直接的磨損(Sun)(除沖刷[Shua]外)。 除一些小排[Pai]量[Liang]泵外(2W.W4.0以下)，一般在泵體[Ti]上都帶有内流式安全(Quan)閥，當排放壓力超[Chao]過額定值時，有一[Yi]定的保護作用。 泵體(Ti)上的進出口方(Fang)向有兩(Liang)種，一為水平進，水平出;二(Er)為水平進，垂直[Zhi]向上出;用戶可根據[Ju]自己需要選擇。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. ●性能參數的選擇： 1. 流量 Q ： 作為容積式泵，影(Ying)響雙螺杆泵流量(Liang)的因素[Su]主要[Yao]有轉速[Su] n ，壓力 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 n 的影響： 螺杆泵(高溫(Wen)雙(Shuang)螺杆泵,大流量雙[Shuang]螺杆泵)在工作(Zuo)時，兩螺杆及襯[Chen]套(Tao)之間形成密封腔，螺[Luo]杆每轉(Zhuan)動一周便由進[Jin]口向(Xiang)出口移出一個(Ge)密封腔，即一個密封腔的[De]體積的液體被排出(Chu)去。理想狀态下，泵(Beng)内(Nei)部無(Wu)洩漏，那麼(Me)泵的流量與轉速(Su)成[Cheng]正比(Bi)。即： Qth=n*q n---- 轉速； q---- 理(Li)論排量，即泵每(Mei)轉[Zhuan]一周所排出[Chu]的液體體積； 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[De]影響： 雙螺[Luo]杆[Gan]泵(高溫雙螺杆泵(Beng),大流量(Liang)雙螺杆(Gan)泵)實[Shi]際工作過程中，其内部存在洩漏，也稱滑移量。由(You)于泵的密封腔有一定的間隙，且密封腔前、後存在壓(Ya)差 △ P ，因此，有一部分液體回(Hui)流，即(Ji)存在洩漏，洩漏(Lou)量用 △ Q 表示，則 Q=Qth- △ Q.顯而易見，随着密封腔前、後壓差 △ P 升高，洩漏量 △ Q 逐漸增大。對于不同(Tong)型線和結構，影(Ying)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(Zhan)度[Du] v 的影響：試想(Xiang)：将清水和粘稠的漿糊以(Yi)相同的體(Ti)積從漏鬥(Dou)式的(De)容器中洩漏出[Chu]去。顯然水比漿糊要[Yao]洩漏得快。同理，對于(Yu)雙螺[Luo]杆泵，粘度大的(De)流體比粘度[Du]小的液體的洩漏要小，洩漏量與介質(Zhi)粘度有一(Yi)定[Ding]的比例關系。綜上所述，要綜合地考慮以上(Shang)各種因素，通過[Guo]一系(Xi)列的計算[Suan]才(Cai)能精确地知[Zhi]道泵的實際流量是否[Fou]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(Xin)泵不同(Tong)，雙[Shuang]螺杆泵的工作[Zuo]壓力 △ P 由出口負[Fu]載決定，即出口阻力來決定。出口阻力[Li]與泵的出口處的壓力(Li)是匹配的，出口阻力越大，工作(Zuo)壓力也越大。若想知道壓力，則需要用流體力(Li)學的知(Zhi)識對出口阻力精[Jing]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(Zhou)功率 N ： 雙[Shuang]螺杆泵(高溫雙螺杆泵,大流量雙(Shuang)螺杆泵)的軸功率分為兩部[Bu]分，即： Nth---- 液壓功率[Lü]，即壓力液體的能[Neng]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. 對于确定的壓力和流量[Liang]，其液壓功率是一定(Ding)的，因此影響軸功率的因素為[Wei]摩擦率 Nr 。 摩擦功率是由于運動[Dong]部件的摩(Mo)擦而消耗的那部分功率。這些摩擦功率顯然是随着工作壓(Ya)差的增加而增加的，并且[Qie]介質粘度的增加也會引起液體摩[Mo]擦(Ca)功率的增加[Jia]。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，泵的軸功率除了液壓功率外，其中摩擦功率(Lü)随介質粘度及工作壓力而增(Zeng)加，因(Yin)此在選擇配套電機時，介質的粘度也是一個非常重要的參考數據。尤(You)其在輸送高[Gao]粘度介質時，需要作比較精确的計[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. 在計算功率後，選擇[Ze]配套[Tao]電機時[Shi]應遵照(Zhao)樣本(Ben)表格中所規(Gui)定[Ding]的有關[Guan]規[Gui]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(Lü) N---- 軸功率 K---- 功率[Lü]儲備[Bei]系[Xi]數 4. 吸上性能的計算及選擇 ：泵(高溫雙螺杆泵,大流量雙(Shuang)螺杆泵)工作[Zuo]分為以下[Xia]幾個階段(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，此時液體[Ti]連續不斷地沿(Yan)吸入[Ru]管道移動；the liquid move continuously along the suction piping; 4.2 旋轉的螺杆把能量傳給工作液體；rotary screw liquid energy to work; 4.3 壓出，此時(Shi)液體帶有克服(Fu)壓出管道系統所有阻力所必(Bi)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[Ge]階段中，最[Zui]為重要的階段(Duan)是必須保(Bao)證泵(Beng)的吸上條件，泵(Beng)才[Cai]能正常工作，這(Zhe)是泵工作的[De]重要條件，否[Fou]則就會發生氣蝕，即引起[Qi]振動，噪音等問題(Ti)。 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. 汽蝕餘量的計算： The calculation of NPSH: 泵(Beng)的汽蝕餘量 NPSHr 與(Yu)泵的轉速 n ，導程 h 以及泵[Beng]所輸送(Song)介質的粘[Zhan]度 v 等因素都有關系，對我[Wo]廠引進(Jin)的(De) Bornemann 雙螺杆泵用以[Yi]下公式計算： NPSHr=(1.5+0.253VF 1.84345+0.0572VF 1.55)*v 0.4146 VF---- 軸(Zhou)向流[Liu]速， VF=n*h/60(m/s) ； n---- 轉速 (r/min) ； h---- 導程 (m) ； v---- 工(Gong)作粘度 (°E) 。 由此可見，泵[Beng]的 NPSHr 是随 VF ， v 的增大而增(Zeng)大。因此在吸入條件不好的情況下，宜選擇小(Xiao)導程的雙螺杆泵。這在選(Xuan)型時是很(Hen)重(Zhong)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(Qi)蝕餘量 NPSHa 的[De]計算，這裡不再(Zai)闡述。 5.2 想要保持泵正常工作，即不發[Fa]生汽蝕、振動等問題，必須保[Bao]證以下[Xia]條件(Jian)： NPSHa > NPSHr 這即(Ji)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[Shuang]螺杆泵(高溫[Wen]雙螺杆[Gan]泵,大流量雙螺(Luo)杆泵(Beng))的轉速選(Xuan)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(Yi)下問題：Choose a different speed often involve the following questions: 6.1 通過選擇合[He]适的泵轉(Zhuan)速，以達到适當的性能參數如流量[Liang]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(Zhan)度的(De)不同，泵的轉速亦應[Ying]有所改(Gai)變。as the viscosity, the speed of the pump should also be changed. 對于 Boremann 雙螺[Luo]杆泵，粘度的變化是[Shi]決定(Ding)轉速的主要條件，随着粘(Zhan)度的增大[Da]，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[Xuan]擇[Ze]實質也是吸(Xi)上性能的[De]問題，尤[You]其是(Shi)在高粘度的(De)情[Qing]況下，如果轉速選得過高，就會引[Yin]起吸入[Ru]不足，從而産生噪音和振動[Dong]等問題。因此務必(Bi)遵照有關原則選擇轉速(Su)。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. |
