输送煤焦油泵用双螺杆泵流量平稳,压力稳定

    ●该型泵采用双吸式结构，螺杆两端处于同一压力腔中，轴向力可以自行平衡。两端轴承采用外装式，单独采用润滑油(脂)润滑，因而不受输送介质的影响。两螺杆间用一对同步齿轮驱动，螺杆齿面间并不接触，而留有一微小间隙，介质中的杂质并不能对螺杆齿面产生直接的磨损(除冲刷外)。 除一些小排量泵外(2W.W4.0以下)，一般在泵体上都带有内流式安全阀，当排放压力超过额定值时，有一定的保护作用。 泵体上的进出口方向有两种，一为水平进，水平出;二为水平进，垂直向上出;用户可根据自己需要选择。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.     ●性能参数的选择：     1. 流量 Q ：     作为容积式泵，影响双螺杆泵流量的因素主要有转速 n ，压力 p ，以及介质的粘度 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 转速 n 的影响：     螺杆泵(高温双螺杆泵,大流量双螺杆泵)在工作时，两螺杆及衬套之间形成密封腔，螺杆每转动一周便由进口向出口移出一个密封腔，即一个密封腔的体积的液体被排出去。理想状态下，泵内部无泄漏，那么泵的流量与转速成正比。即： Qth=n*q n---- 转速； 　q---- 理论排量，即泵每转一周所排出的液体体积； 　 理论排量。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 压力 △ P 的影响：     双螺杆泵(高温双螺杆泵,大流量双螺杆泵)实际工作过程中，其内部存在泄漏，也称滑移量。由于泵的密封腔有一定的间隙，且密封腔前、后存在压差 △ P ，因此，有一部分液体回流，即存在泄漏，泄漏量用 △ Q 表示，则 Q=Qth- △ Q.显而易见，随着密封腔前、后压差 △ P 升高，泄漏量 △ Q 逐渐增大。对于不同型线和结构，影响大小也各不相同。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 gradually.For different lines and structure, effect size are different.     1.3 粘度 v 的影响：试想：将清水和粘稠的浆糊以相同的体积从漏斗式的容器中泄漏出去。显然水比浆糊要泄漏得快。同理，对于双螺杆泵，粘度大的流体比粘度小的液体的泄漏要小，泄漏量与介质粘度有一定的比例关系。，要综合地考虑以上各种因素，通过一系列的计算才能地知道泵的实际流量是否符合工况要求。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 re     2. 压力 △ P ：     与离心泵不同，双螺杆泵的工作压力 △ P 由出口负载决定，即出口阻力来决定。出口阻力与泵的出口处的压力是匹配的，出口阻力越大，工作压力也越大。若想知道压力，则需要用流体力学的知识对出口阻力的计算。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. 轴功率 N ：     双螺杆泵(高温双螺杆泵,大流量双螺杆泵)的轴功率分为两部分，即： Nth---- 液压功率，即压力液体的能量； 　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.     对于确定的压力和流量，其液压功率是一定的，因此影响轴功率的因素为摩擦率 Nr 。     摩擦功率是由于运动部件的摩擦而消耗的那部分功率。这些摩擦功率显然是随着工作压差的增加而增加的，并且介质粘度的增加也会引起液体摩擦功率的增加。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，泵的轴功率除了液压功率外，其中摩擦功率随介质粘度及工作压力而增加，因此在选择配套电机时，介质的粘度也是一个非常重要的参考数据。尤其在输送高粘度介质时，需要作比较的计算。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.     在计算功率后，选择配套电机时应遵照样本表格中所规定的有关规定。     N(KW) N≤10 10 < N≤50 N > 50 N > 100 　K 1.5 1.25 1.15 1.1 　Nm=N.K 　Nm---- 电机功率 N---- 轴功率 K---- 功率储备系数     4. 吸上性能的计算及选择 ：泵(高温双螺杆泵,大流量双螺杆泵)工作分为以下几个阶段： 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，此时液体连续不断地沿吸入管道移动；the liquid move continuously along the suction piping;     4.2 旋转的螺杆把能量传给工作液体；rotary screw liquid energy to work;     4.3 压出，此时液体带有克服压出管道系统所有阻力所必需的压力从泵中排出。pressure, the liquid with necessary to overcome all delivery pipeline system pressure from the eduction in pump.     在以上三个阶段中，Zui为重要的阶段是必须保证泵的吸上条件，泵才能正常工作，这是泵工作的重要条件，否则就会发生气蚀，即引起振动，噪音等问题。 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. 汽蚀余量的计算： The calculation of NPSH:     泵的汽蚀余量 NPSHr 与泵的转速 n ，导程 h 以及泵所输送介质的粘度 v 等因素都有关系，对我厂引进的 Bornemann 双螺杆泵用以下公式计算： NPSHr=(1.5+0.253VF 1.84345+0.0572VF 1.55)*v 0.4146 　VF---- 轴向流速， VF=n*h/60(m/s) ； 　n---- 转速 (r/min) ； 　h---- 导程 (m) ； 　v---- 工作粘度 (°E) 。 　由此可见，泵的 NPSHr 是随 VF ， v 的增大而增大。因此在吸入条件不好的情况下，宜选择小导程的双螺杆泵。这在选型时是很重要的。  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 装置汽蚀余量 NPSHa 的计算，这里不再阐述。     5.2 想要保持泵正常工作，即不发生汽蚀、振动等问题，必须保证以下条件： NPSHa > NPSHr 这即是泵的吸入条件。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. 双螺杆泵(高温双螺杆泵,大流量双螺杆泵)的转速选择：Double screw pump (high temperature double screw pump, large flow of double screw pump) the speed of choice:     选择不同的转速常牵涉以下问题：Choose a different speed often involve the following :     6.1 通过选择合适的泵转速，以达到适当的性能参数如流量等。by selecting the appropriate pump rotation speed, in order to achieve the appropriate performance parameters such as flow rate, etc.     6.2 随着粘度的不同，泵的转速亦应有所改变。as the viscosity, the speed of the pump should also be changed.     对于 Boremann 双螺杆泵，粘度的变化是决定转速的主要条件，随着粘度的增大，允许转速也越低。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.     转速的选择实质也是吸上性能的问题，尤其是在高粘度的情况下，如果转速选得过高，就会引起吸入不足，从而产生噪音和振动等问题。因此务必遵照有关原则选择转速。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.         ●双螺杆泵如何进行日常维护与保养:daily maintenance and maintenance:     1、每日的维护和保养1, daily maintenance and maintenance
