概述：
三螺杆泵是转子式容积泵，它是利用螺杆啮合原理，依靠旋转的螺杆在泵套内相互啮合，把被输送的介质封闭在啮合腔内，沿螺杆轴向连续匀速地推至排出口，为系统提供稳定的压力。
三螺杆泵适用于各种无腐蚀性油类及类似油和润滑性液体。输送液体的粘度范围一般为3.0-760mm2/s(1.2-100oE),高粘度介质可通过加温降粘后输送。其温度不超过350℃。
我公司生产的LQ3G保温螺杆泵（保温型沥青泵）主要用于输送高粘度和高温润滑性液体。常用于沥青重燃油、重齿轮油等介质的输送。热载体可以是蒸汽、热油和热水，冷载体可以是气体和液体。
特点：
三螺杆泵的显著特点是结构简单、压力脉动小、流量稳定、工作平衡可靠、允许高转速、噪音低，效率高、寿命长、有自吸能力。
用途及使用范围：
三螺杆泵广泛应用于石油、化纤、冶金、机械、电力、机床、船舶、玻璃、公路等各行各业。
三螺杆泵适用于输送燃料油、润滑油、液压油、原油、沥青及其它类似油的润滑油和润滑性液体。
三螺杆泵在工业领域中作润滑泵，在液压系统中作液压泵，在燃油系统中作输送及增压泵，在输油系统中作输送及加油泵。
流量范围0.2-600m3/h,最高工作压力可达6.3MPa。
