●雙螺桿泵系列產(chǎn)品分為單吸雙螺桿泵和雙吸雙螺桿泵兩大類。該系列產(chǎn)品具有特殊的螺桿型線和與之配套的特殊結(jié)構(gòu)，廣泛適用于石油、化工、冶金、鋼鐵、電力、船舶、制藥、食品、建材等各種行業(yè)，其適用介質(zhì)之多、輸送范圍之廣、應(yīng)用工況之復雜是其它泵類產(chǎn)品無法比擬的。這些特點也使得該系列泵具有潛在的使用發(fā)展前景。Doublescrew pump series products are divided into single suction of twokinds of double screw pump and double suction double screwpump.This series of products have special screw lines and form acomplete set with the special structure, widely used in petroleum,chemical industry, metallurgy, steel, electricity, shipbuilding,pharmaceutical, food, building materials and other industries, byas much as its applicable medium, transmission range wide,application condition of the complex is unmatched by other pumpproduct.These features also makes the use of this series of pumpswith potential development prospects.
●泵體內(nèi)裝有兩根左、有施單頭螺紋的螺桿，主動螺桿2由動力機驅(qū)動轉(zhuǎn)動時，靠同步齒輪1帶動從動螺桿3轉(zhuǎn)動。兩根螺桿以及螺桿與泵體.之間存在著間隙，該間隙靠齒輪和軸承保證。其間隙大小，取決于液體粘度、工作壓力等因素。由于每根螺桿兩端螺紋的旋向相反，螺桿轉(zhuǎn)動時，由螺桿嚙合線形成的泵工作腔。E two left in the pump body, a single thread screw, active screwdriven by engine 2 turns, driven by synchronous gear 1 driven screw3 rotation.Two screw and screw and pump body. There is a gapbetween the gap by gear and bearing.The gap size, depends on theliquid viscosity, pressure and other factors.Because each threadrotate to the opposite on both ends of the screw, the screwrotates, formed by the screw meshing line pump workingchamber.
●氣液混輸泵采用雙吸式結(jié)構(gòu)，螺桿兩端處于同一壓力腔中，軸向力可以自行平衡。兩端軸承采用外裝式，單獨采用潤滑油(脂)潤滑，因而不受輸送介質(zhì)的影響。兩螺桿間用一對同步齒輪驅(qū)動，螺桿齒面間并不接觸，而留有一微小間隙，介質(zhì)中的雜質(zhì)并不能對螺桿齒面產(chǎn)生直接的磨損(除沖刷外)。除一些小排量泵外(2W.W4.0以下)，一般在泵體上都帶有內(nèi)流式安全閥，當排放壓力超過額定值時，有一定的保護作用。泵體上的進出口方向有兩種，一為水平進，水平出;二為水平進，垂直向上出;用戶可根據(jù)自己需要選擇。This type pumpadopts double suction type structure, at the same pressure in thecavity on both ends of the screw, the axial force can balanceitself.Both ends of bearing mounted outside using, lubricated bylubricating oil (grease) separately, and therefore not affected bythe medium.With a pair of synchronous gears drive between the twoscrew, the screw does not contact between tooth surfaces, and leavea small gap, the impurities in medium can not be directly on thescrew tooth surface wear (except wash).Except a few smalldisplacement pump (below 2 w. W4.0), generally contain flow reliefvalve on the pump body, when the discharge pressure exceeds rating,has certain protective effect.There are two kinds of the directionof the import and export on the pump body, one for level,level;Secondly, level, vertical;User can choose according to theirown needs.
●氣液混輸泵性能參數(shù)的選擇：
1. 流量 Q ：
作為容積式泵，影響雙螺桿泵流量的因素主要有轉(zhuǎn)速n ，壓力 p ，以及介質(zhì)的粘度 v 。The selection of performanceparameters:
1. The flow Q:
As a positive displacement pump, double screw pump floweffects are the major factors of rotational speed n, pressure p,and the medium viscosity v.
1.1 轉(zhuǎn)速 n的影響：
氣液混輸泵(高溫雙螺桿泵,大流量雙螺桿泵)在工作時，兩螺桿及襯套之間形成密封腔，螺桿每轉(zhuǎn)動一周便由進口向出口移出一個密封腔，即一個密封腔的體積的液體被排出去。理想狀態(tài)下，泵內(nèi)部無泄漏，那么泵的流量與轉(zhuǎn)速成正比。即：Qth=n*q n---- 轉(zhuǎn)速； q---- 理論排量，即泵每轉(zhuǎn)一周所排出的液體體積； 理論排量。Theinfluence of the rotational speed n 1.1:Screw pump (hightemperature double screw pump, large flow of double screw pump) atwork, the sealed cavity formed between the two screw and bushing,the screw rotation per week will remove a sealed cavity from importto export, that is, a sealed cavity volume of liquid isout.Internal leak-off ideally, pump, the pump flow rate isproportional to the speed.Namely: Qth q = n * n - speed;Q - thetheory of displacement, the pump discharge by turn everyuid volume;Qth - the theory of displacement.
1.2 壓力 △ P的影響：
雙螺桿泵(高溫雙螺桿泵,大流量雙螺桿泵)實際工作過程中，其內(nèi)部存在泄漏，也稱滑移量。由于泵的密封腔有一定的間隙，且密封腔前、后存在壓差△ P ，因此，有一部分液體回流，即存在泄漏，泄漏量用 △ Q 表示，則 Q=Qth- △ Q.顯而易見，隨著密封腔前、后壓差 △ P升高，泄漏量 △ Q 逐漸增大。對于不同型線和結(jié)構(gòu)，影響大小也各不相同。The influence of pressure deltaP 1.2:
Double screw pump (high temperature double screw pump, largeflow of double screw pump) in the process of the actual work, itsinternal is leaking, also known as slippage.Due to pump sealchamber has a certain gap, and seal chamber before and after thedifferential delta P, as a result, some liquid reflux, is leakage,leakage in delta Q, Q = Qth - delta Q. Obviously, as the sealchamber pressure difference before and after the delta P increases,leakage delta gradually.For different lines andstructure, effect size are different.
1.3 粘度 v的影響：試想：將清水和粘稠的漿糊以相同的體積從漏斗式的容器中泄漏出去。顯然水比漿糊要泄漏得快。同理，對于雙螺桿泵，粘度大的流體比粘度小的液體的泄漏要小，泄漏量與介質(zhì)粘度有一定的比例關(guān)系。，要綜合地考慮以上各種因素，通過一系列的計算才能地知道泵的實際流量是否符合工況要求。Theinfluence of the viscosity of 1.3 v: just think: will clear waterand the volume of the sticky paste with the same leak out from thefunnel type of container.Obviously water leak faster thanpaste.Similarly, for double screw pump, the viscosity of the fluidis larger than that of low viscosity liquid leakage, leakage andthe proportion of medium viscosity have a certainrelationship.Above all, should be synthetically considered theabove factors, through a series of calculations to accurately knowthe actual flow of the pump is in accordance with the workingcondition re
2. 壓力 △ P ：
與離心泵不同，雙螺桿泵的工作壓力 △ P由出口負載決定，即出口阻力來決定。出口阻力與泵的出口處的壓力是匹配的，出口阻力越大，工作壓力也越大。若想知道壓力，則需要用流體力學的知識對出口阻力的計算。2.Pressure delta P:
Unlike centrifugal pump, double screw pump working pressuredelta P is determined by export load, namely export resistance todecide.Export resistance is matching with the pump outlet pressure,export the resistance, the greater the pressure of work.If want toknow the pressure, you may need to drag on exports by the knowledgeof fluid mechanics calculations.
3. 軸功率 N ：
氣液混輸泵(高溫雙螺桿泵,大流量雙螺桿泵)的軸功率分為兩部分，即： Nth---- 液壓功率，即壓力液體的能量； Nr---- 摩擦功率。3. The shaft power N:
Double screw pump (high temperature double screw pump, largeflow of double screw pump) of the shaft power is divided into twoparts, i.e., the Nth, hydraulic power, namely of liquid pressureenergy;Nr - friction power.
對于確定的壓力和流量，其液壓功率是一定的，因此影響軸功率的因素為摩擦率 Nr 。
摩擦功率是由于運動部件的摩擦而消耗的那部分功率。這些摩擦功率顯然是隨著工作壓差的增加而增加的，并且介質(zhì)粘度的增加也會引起液體摩擦功率的增加。Todetermine the pressure and flow rate, the hydraulic power iscertain, so the influence of shaft power factor for the frictionratio of Nr.Friction power is due to the friction in the movingparts and the part of the power consumption.The friction power isobviously increases with the increase of the pressure difference,and the increase of viscosity of medium can also cause the li power increases.
由此，泵的軸功率除了液壓功率外，其中摩擦功率隨介質(zhì)粘度及工作壓力而增加，因此在選擇配套電機時，介質(zhì)的粘度也是一個非常重要的參考數(shù)據(jù)。尤其在輸送高粘度介質(zhì)時，需要作比較的計算。Thus,the pump shaft power in addition to the hydraulic power, thefriction power increases with medium viscosity and the pressure ofwork, therefore, when choosing motor medium viscosity is also avery important reference data.Especially in transport highviscosity medium, the need for accurate calculation.
在計算功率后，選擇配套電機時應(yīng)遵照樣本表格中所規(guī)定的有關(guān)規(guī)定。
N(KW) N≤10 10 < N≤50N > 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---- 功率儲備系數(shù)
4. 吸上性能的計算及選擇：泵(高溫雙螺桿泵,大流量雙螺桿泵)工作分為以下幾個階段： 4. On the absorptionperformance of calculation and selection: pump (high temperaturedouble screw pump, large flow of double screw pump) work is dividedinto the following stages:
4.1吸入，此時液體連續(xù)不斷地沿吸入管道移動；the liquid move continuously along thesuction piping;
4.2旋轉(zhuǎn)的螺桿把能量傳給工作液體；rotary screw liquid energy towork;
4.3壓出，此時液體帶有克服壓出管道系統(tǒng)所有阻力所必需的壓力從泵中排出。pressure, the liquid withnecessary to overcome all delivery pipeline system pressure fromthe eduction in pump.
在以上三個階段中，Zui為重要的階段是必須保證泵的吸上條件，泵才能正常工作，這是泵工作的重要條件，否則就會發(fā)生氣蝕，即引起振動，噪音等問題。In the above three stages, the most important stage is mustensure that the suction on the condition of the pump, pump can worknormally, this is the important condition of pump work, otherwisecavitation occurs, which cause vibration, noise and otherissues.
