双螺杆泵选型步骤：
Double screw pump selection steps:
双螺杆泵和三螺杆泵单螺杆泵的选型步骤有所不同，
Selection steps of double screw pump and the three screw pump of single screw pump is different,
1.双螺杆泵和三螺杆泵zui大的区别就是双螺杆泵能输送各种具有流动性的液体和没有流动性的固体，介质润滑性的好坏对于双螺杆泵来说显得就不是那么的重要，对输送有腐蚀性的介质我们将采用不锈钢材质为客户订制适合您现场使用产品，国产的三螺杆泵和双螺杆泵相比就显得比较娇贵，三螺杆泵一般适合输送各种润滑性良好无腐蚀性的介质，对于输送重油，柴油，等润滑性差的介质三螺杆泵就要采用外置机械密封，尽管外置机械密封是避免了因为磨损而造成机械密封漏油的情况发生，但是避免不了螺杆与螺杆摩擦，*输送润滑性差介质，会使螺杆磨损 ，就会造成泵的压力上不去，流量损失等，对三螺杆泵的使用寿命造成严重威胁。
The difference between the 1 double screw pump and the three screw pump is the largest double screw pump can transport all kinds of liquid liquid and no solid flow, lubrication of the twin screw pump is not so important, forconveying corrosive medium, we will adopt stainless steel material is customized for your site using the product,three screw pump domestic and double screw pump compared to appear more delicate, three screw pump issuitable for conveying various good lubricity and non corrosive medium, for transferring heavy oil, diesel oil, such as poor lubrication medium three screw pump is a double mechanical seal, although the external mechanical seal is avoid because of wear caused by mechanical seal leakage situation, but could not avoid friction screw and screw conveyor, long-term poor lubrication medium, can make the screw wear, will cause the pump pressure can not go up, flow loss, a serious threat to the three screw pump life.
2.双螺杆泵输送的流量范围广，从1 m3/h到8600 m3/h，而三螺杆泵的流量1m3/h到600m3/h，所以在许多油田上用大流量原油输送泵和船舶上用主机润滑泵，货油泵三螺杆泵很少被列入设计院选型范围之内。
2 double screw pump flow range, from 1 m3/h to 8600 m3/h, and the three screw pump flow from 1m3/h to600m3/h, so in many oil fields with large flow of crude oil lubricating pump pump and on ships, cargo oil pumpthree screw pump is rarely included in the selection range within the design institute.
3.双螺杆泵能承受的温度范围广，从~20°C到500°C，而三螺杆泵承受的温度范围~10°C到200°C。
The temperature range of 3 double screw pump can withstand the wide, ranging from ~20 °C to 500 °C, and the three screw pump bearing temperature range of ~10 ° C to 200 °C.
4.双螺杆泵的应用行业广：
Application of 4 double screw pump industry wide
双吸双螺杆泵、双螺杆泵、高温髙粘双螺杆泵优点
Double suction and double screw pump, double screw pump, high temperature and high viscosity of double screwpump has the advantages of
1、双螺杆泵具有流量大，自吸能力好，噪声低，寿命长，配置形式多，适应性广。
1, double screw pump with large flow, the self absorption ability, low noise, long service life, configuration, wide adaptability.
2、有很强的自吸性能，多相混输时，含气率不高于60％，双螺杆泵适用于具有润滑性无固体杂质的各种油品的输送，双螺杆泵适用于不含固体杂质的各种介质的输送包含各种油品化学品及高分子物料的输送。
2, there are self-priming performance is very strong, multiphase, gas rate no higher than 60%, conveying double screw pump is suitable for all kinds of oil with lubrication without solid impurity, the transmission of double screw pump is suitable for various medium not containing solid impurity containing various oil chemicals and polymer materials
3、外置轴承结构，采 用独立润滑，允许输送各种非润滑性介质。
3, external bearing structure, the independent lubrication, allowing delivery of various non lubricating medium.
4、采用同步齿轮驱动，二转子之间不接触，即使短时间空转也无妨。
4, the synchronous gear drive, no contact between the two rotors, even for a short time idle it anyway.
5、泵体带有加热套，可以输送各种清洁或含有固体小颗粒的低粘度或高粘度介质（一般颗粒直径小于0.12-0.2mm）
5, the pump body is provided with a heating sleeve, can transport all kinds of cleaning or containing small particles of solid low or high viscosity media （average particle diameter is less than 0.12-0.2mm）
6、正确的选用材料，甚至可以输送很多有腐蚀性的介质。
6, the correct selection of material, and can transport a lot of corrosive medium.
7、双吸式结构，转子上没有轴向力。
7, double suction structure, no axial force on the rotor.
8、轴端采用机械密封或波纹管机械密封，具有寿命长、泄漏少、适用范围广等特点。
8, end of the shaft with mechanical seal or bellows mechanical seal, has the characteristics of long service life,less leakage, wide application range etc..
双螺杆泵、双吸双螺杆泵结构特点
Double screw pump, double suction and double screw pump structure
该型双螺杆泵采用双吸式结构，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）
This type of twin screw pump double suction structure, the two ends of the screw bolt at the same pressurechamber, the axial force can be balanced. Two ends of the bearing with external mounted, single used lubricating oil （grease） lubrication, so it is not affected by the transmission medium, two screw with a synchronous gear drive,the screw does not contact between the tooth surface, and leave a small gap, the impurities in the medium did notscrew tooth surface wear （direct in addition to scour）.
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，有一定保护作用。泵体上的进出口方向有二种，一为水平出；二为水平进，垂直向上出；用户可根据自己需要选择。
General in the pump body with internal flow type safety valve, when the discharge pressure exceeds the rated value, have certain protection effect. The pump body of the import and export orientation has two kinds, one ishorizontal; the level, vertical upwards; the user can choose according to their own needs.
