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。型号流量出口压力MPa转速r/min功率KW必需汽蚀余量电机型号m3/hL/min轴功率电机功率45×3-362.8460.69500.81.1590L-6-B32.7451.01.21.5100L-6-B325421.61.62.2112M-6-B32.4402.52.84132M1-6-B34.2700.614501.01.5590L-4-B34.0661.01.72.2100L1-4-B33.8631.62.83100L3-4-B33.5582.54.35.5132S-4-B345×2-464.2700.69501.01.55100L-6-B34.0661.01.72.2112M-6-B36.31050.614501.52.2100L1-4-B36.11011.02.33100L2-4-B354×2-468.01330.89702.335100L-6-B38.01331.01.52.2112M-6-B3142330.614502.84100L1-4-B3142334.04.35.5100L2-4-B362×2-438.58143.40.69502.0635132S-6-B38.25137.91.03.184132M1-6-B313.1218.90.614503.154112M-4-B312.6210.51.04.867.5132M-4-B362×2-469.81630.89502.945132M1-6-B39.51581.03.65.5132M2-6-B315.12510.614503.65.5132S-4-B314.62431.05.57.5132M-4-B380×2-3617.0283.30.89504.37.55.5160M-6-B325.74280.614505.47.5132M-4-B325.04171.08.511160M-4-B380×2-4623.9398.50.69505.57.55.5160M-6-B323.1386.31.08.611160L-6-B336.6610.30.614508.411160M-4-B335.7594.51.013.115160L-4-B380×2-5127.5485.50.69506.3115.5160L-6-B326.9448.31.010.515180L-6-B341.9698.30.614509.611160M-4-B341.0684.11.016.018.5180M-4-B390×2-3624.2403.50.69605.527.55.5160M-6-B323.6394.61.08.5211160L-6-B337615.90.614508.5211160M-4-B336.1602.41.01315160L-4-B390×2-4228.2470.90.69506.6115.5160L-6-B327.5457.61.010.215180L-6-B343.1718.80.614501015160L-4-B341.9698.51.015.518.5180M-4-B390×2-4634.0566.70.89509.7115.5160L-6-B352.6875.40.614501215160L-4-B352.08660.814.918.5180M-4-B351.4856.11.018.622180L-4-B3100×2-4648.08000.895013.3155.5180L-6-B372.712120.6145016.518.5180M-4-B372.012000.820.422180L-4-B371.211871.025.530200L-4-B3100×2-5156.9948.90.695012.5155.5180L-6-B355.7928.61.020.830225L-6-B386.91448.30.6145019.122180L-4-B385.01417.21.031.837225S-4-B3110×2-4660.910150.695013.718.55.5200L1-6-B358.9951.71.021.830255M-6-B396.716110.6145021.930200L-4-B394.615771.033.945255M-4-B3120×2-4267.911310.695015.518.55.5200L1-6-B365.410901.024.530255M-6-B310818020.6145024.730200L-4-B310517601.038.245255M-4-B3120×2-4679.613270.695017.8225.5200L1-6-B377.212851.028.237250M-6-B312621010.6145028.537225S-4-B312320591.044.155255M-4-B3150×2-4615826400.695034.6455.5Y280S-6-B315425821.054.575Y315S-6-B3241.74029.70.6145053.875Y280S-4-B3236.53942.21.082.290Y280M-4-B3
