一、螺杆泵概述：
三螺杆泵是无脉动轴向输送具有一定润滑性介质的定量容积式低压转子泵，适于输送燃料油、润滑油、液压油、矿物油等油类和具有润滑性的流动性液体。所输送的介质中不得含有任何磨料颗粒和对泵材料有腐蚀的物质。SNH系列三螺杆泵由特殊型线（摆线）构成的螺旋型面，当电机或马达驱动主动螺杆转动时，其不断运动的各个密封腔室逐渐形成真空，液体在大气压的作用下由吸入口吸入并沿轴向连续、无脉动的输送到排出口，无搅拌、乳化现象。
二、螺杆泵性能特点：
1、转子液压平衡，输出稳定，无脉动。
2、效率高>低运营成本
3、轴向平衡转子>轴承没有轴向力，振动小，噪音低。
4、只有一个轴密封>易于维护,低成本
5、具有很强的自吸能力，抗汽蚀能力强>低噪音、最小化的振动
6、简单的设计，结构紧凑，体积小，重量轻，可在较高转速下工作>合理的价格
7、可设计成无密封磁力或半潜油泵
8、进出口可以通过翻转泵体实现互换>通用性强
9、螺杆泵可以更换的螺杆，衬套，泵芯>螺杆泵零部件全系列通用互换
三、螺杆泵主要技术参数：
1、流量范围：10～10000 L/min (升/分钟) 0.6～600m3/h (立方/小时)
2、压力范围：0～4 Mpa（兆帕）0～40 bar（巴） 0-40 kg/f (公斤力/平方厘米)
3、输送介质粘度范围：2-10000 cst（厘斯）
4、泵送温度：300 ℃ （摄氏度）
5、容许最高转速：3600 r/min （转/分钟）

七、螺杆泵选型资料样本：
八、关于螺杆泵组选型配置须知及使用开机注意事项的重要说明：（供设计院和现场安装使用维护人员参考）
1、严禁无介质空转，启动开车前请务必加入润滑性介质或输送介质。
2、严禁一切杂物焊渣等进入泵腔内，务必保持泵腔和管道内部的清洁度。
3、严禁使用管道过滤器或Y型过滤器装置，配置过滤器请保证过滤面积是泵进口通径截面积的20-40倍。并依据介质的清洁度正确配置过滤网的目数。
4、严禁泵的进出口管道与泵的进出口管道不匹配，管道通径配置必须和泵的进出口通径一致。以避免发生汽蚀或无法自吸。管道过细必定导致汽蚀，从而使泵处于吃不饱的状态下工作，导致三螺杆泵组流量压力下降甚至是异常的振动和噪音，长时间运行还将导致卡泵和螺杆泵的严重损坏，
5、三螺杆泵的安装高度必须充分考虑泵的汽蚀条件和泵的自吸能力（汽蚀余量与介质粘度 转速和螺杆的导程有关）
6、由于包装 运输 起吊 装卸以及管道螺栓紧固的作用可能易使泵的原出厂定位产生变化甚至严重错位，所以三螺杆泵组管系配置安装固定完毕后，一定要在启动开车之前重新检查三螺杆泵和电机的同轴度。
7、严禁背压启动开机和关闭进口出口阀门的情况下启动开机。
8、严禁不符合泵旋转标识的方向启动旋转。
9、双泵并联必须在泵的出口和进口加单向阀，以防止介质倒流驱动三螺杆泵反转。
10、严禁随意调整安全阀螺栓。安全阀仅作为保护泵的安全和电机功率与泵工作状态的匹配，严禁作为调压阀和溢流阀使用。
