SNH660R46E6.7W29增压螺杆泵介绍：
SNH焊接保温螺杆泵我公司在SN系列基础上派生出来的双层加热泵体结构，其泵体是用钢管和钢板焊接而成的。在外层加热套的水平对称位置焊接一对蒸汽进出管，蒸汽进入加热套内作为传输液体，对所输送的介质进行加热及预热（蒸汽吹扫温度≤280℃）。该泵主要用于石油、化工、炼油厂、油库、输油站等行业，输送高粘度，流动性差的液体，如：重油，渣油，沥青，原油等。

沥青增压螺杆泵SNH660R46E6.7W29保温螺杆泵特点:
1、 结构先进，性能优越：改变传统高压平衡技术，采用主、从杆的轴向力低压平衡装置，受力平衡均匀，螺杆不变形，运行可靠稳定，无脉动，噪音低；
2、 独特设计，密封可靠：泵采用机械密封形式，密封腔压力与吸入压力相通，同时结构设计上对密封充分冷却循环，保证密封效果，无泄漏；
3、 优化改进，外形美观：改变传统的进、出口的位置，使得进出口分布在泵两侧并成一条直线，外形美观，同时在设计上进行创新，在用户现场不用改变管线就可实现进出口的互换；
4、 泵芯组件，方便维修和配件更换：泵结构简单紧凑，泵芯总成采用组件式结构，可整体取出，便于维护、修理；
5、 安全阀组件，保护原油泵安全：原油泵所配安全阀可以瞬间保护泵，防过载，但不能作为管道的溢流阀使用；
6、 进出口多种组合形式，方便现场管道连接；
7、 多种安装方式，更好满足工况安装要求

三螺杆泵选型要点：
1.首先应根据油品的粘度选择适当的泵转速，以保证泵的（NPSH）r能满足用户的实际吸入条件。
2.介质粘度V＞760mm2/s时，请与我厂联系，我厂帮助用户先泵。
3.从性能表中选定泵的规格及相应粘度下的压力流量后，可以查到泵的轴功率N，选定配套电机功率Nm时应功率备量。
Nm≥K×N其值参见下表：
N（Kw）
N≤5
5＜N≤10
10＜N≤50
N＞50
K
1.25
1.2
1.15
1.1
4.材料的选择
①输送柴油、重油、沥青、（燃料油），泵套用锡青铜。
②输送润滑油、液压油，泵套用灰铸铁、球铁、锡青铜。
如果确定好流量和压力，请核对下表，看看相对应的流量和压力下，泵的轴功率是多少，然后选电机，在您初步选好型以后，尽快与我厂技术部联系确认，在安排下单。
