●該型泵采用雙吸式結(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(dú)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(duì)同步齒輪驅(qū)動(dòng),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(duì)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(dāng)排放壓力超過額定值時(shí),有一定的保護(hù)作用。泵體上的進(jìn)出口方向有兩種,一為水平進(jìn),水平出;二為水平進(jìn),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. ●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 performance parameters: 1. The flow Q: As apositive displacement pump, double screw pump flow effects are themajor factors of rotational speed n, pressure p, and the mediumviscosity v. 1.1 轉(zhuǎn)速 n 的影響: 螺桿泵(高溫雙螺桿泵,大流量雙螺桿泵)在工作時(shí),兩螺桿及襯套之間形成密封腔,螺桿每轉(zhuǎn)動(dòng)一周便由進(jìn)口向出口移出一個(gè)密封腔,即一個(gè)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(shí)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(duì)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(duì)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(jì)算才能地知道泵的實(shí)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(fù)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(xué)的知識(shí)對(duì)出口阻力的計(jì)算。2.Pressure delta P: Unlike centrifugal pump, double screw pumpworking pressure delta P is determined by export load, namelyexport resistance to decide.Export resistance is matching with thepump outlet pressure, export the resistance, the greater thepressure of work.If want to know the pressure, you may need to dragon exports by the knowledge of fluid mechanics calculations. 3. 軸功率 N : 雙螺桿泵(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 temperaturedouble screw pump, large flow of double screw pump) of the shaftpower is divided into two parts, i.e., the Nth, hydraulic power,namely of liquid pressure energy;Nr - friction power. 對(duì)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(yùn)動(dòng)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(huì)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(jī)時(shí),介質(zhì)的粘度也是一個(gè)非常重要的參考數(shù)據(jù)。尤其在輸送高粘度介質(zhì)時(shí),需要作比較的計(jì)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(jì)算功率后,選擇配套電機(jī)時(shí)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≤50 N > 50 N > 100 K1.5 1.25 1.15 1.1 Nm=N.K Nm---- 電機(jī)功率 N---- 軸功率 K---- 功率儲(chǔ)備系數(shù) 4. 吸上性能的計(jì)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(gè)階段: 4.On the absorption performance of calculation and selection: pump(high temperature double screw pump, large flow of double screwpump) work is divided into the following stages: 4.1 吸入,此時(shí)液體連續(xù)不斷地沿吸入管道移動(dòng);the liquid move continuously along thesuction piping; 4.2 旋轉(zhuǎn)的螺桿把能量傳給工作液體;rotaryuid energy to work; 4.3壓出,此時(shí)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(gè)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(huì)發(fā)生氣蝕,即引起振動(dòng),噪音等問題。In the above three stages, the most important stage is must ensurethat 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 other issues. 5. 汽蝕余量的計(jì)算: The calculation of NPSH: 泵的汽蝕余量 NPSHr 與泵的轉(zhuǎn)速 n ,導(dǎo)程 h 以及泵所輸送介質(zhì)的粘度 v等因素都有關(guān)系,對(duì)我廠引進(jìn)的 Bornemann 雙螺桿泵用以下公式計(jì)算: NPSHr=(1.5+0.253VF1.84345+0.0572VF 1.55)*v 0.4146 VF---- 軸向流速, VF=n*h/60(m/s) ; n---- 轉(zhuǎn)速 (r/min) ; h---- 導(dǎo)程 (m) ; v---- 工作粘度 (°E) 。 由此可見,泵的NPSHr 是隨 VF , v 的增大而增大。因此在吸入條件不好的情況下,宜選擇小導(dǎo)程的雙螺桿泵。這在選型時(shí)是很重要的。 Pump NPSH NPSHr and pump speed n, lead h and the medium viscosity vpump etc have relations, to my factory to introduce Bornemanndouble 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 thecase of suction condition is bad, should choose small lead ofdouble screw pump.This when selection is very important. 5.1 裝置汽蝕余量 NPSHa 的計(jì)算,這里不再闡述。 5.2 想要保持泵正常工作,即不發(fā)生汽蝕、振動(dòng)等問題,必須保證以下條件: NPSHa > NPSHr 這即是泵的吸入條件。tokeep the normal work of the pump, that is, do not produce theproblem such as cavitation, vibration, must ensure that thefollowing conditions: NPSHa > NPSHr this is pump suctionconditions. 6. 雙螺桿泵(高溫雙螺桿泵,大流量雙螺桿泵)的轉(zhuǎn)速選擇:Doublescrew pump (high temperature double screw pump, large flow ofdouble screw pump) the speed of choice: 選擇不同的轉(zhuǎn)速常牽涉以下問題:Choose a different speed often involve the following: 6.1 通過選擇合適的泵轉(zhuǎn)速,以達(dá)到適當(dāng)?shù)男阅軈?shù)如流量等。byselecting the appropriate pump rotation speed, in order to achievethe appropriate performance parameters such as flow rate, etc. 6.2 隨著粘度的不同,泵的轉(zhuǎn)速亦應(yīng)有所改變。as the viscosity, thespeed of the pump should also be changed. 對(duì)于Boremann 雙螺桿泵,粘度的變化是決定轉(zhuǎn)速的主要條件,隨著粘度的增大,允許轉(zhuǎn)速也越低。For Boremann doublescrew pump, the change of viscosity is the main condition of ionspeed, with the increase of viscosity, allow rotation speed islower. 轉(zhuǎn)速的選擇實(shí)質(zhì)也是吸上性能的問題,尤其是在高粘度的情況下,如果轉(zhuǎn)速選得過高,就會(huì)引起吸入不足,從而產(chǎn)生噪音和振動(dòng)等問題。因此務(wù)必遵照有關(guān)原則選擇轉(zhuǎn)速。Speedselection essence is also on the absorption performance problems,especially in the case of high viscosity, if speed selected toohigh, it will cause insufficient suction, so as to produce theproblem such as noise and vibration.So be sure to follow relevantprinciples to choose speed. ●雙螺桿泵如何進(jìn)行日常維護(hù)與保養(yǎng):daily maintenance and maintenance: 1、每日的維護(hù)和保養(yǎng)1, daily maintenance and maintenance
