三螺杆泵概述：

三螺杆泵在国际上主要应用于石油，化工，冶金，机床，造船等工业部门得到了较为广泛的应用。并在很多领域里代替了离心泵、齿轮泵和往复泵，德国巴赫设计生产的3G型、3GBW型、3Gr型螺杆泵有着寿命长、效率高、能耗小、重量轻等特点。3G、3Gr系列普通三螺杆泵主要用于输送中低粘度的润滑性液体。在工业生产中作为液压泵、润滑泵、轻燃油泵、输送泵。泵有基础件：泵套、泵体、螺杆和附件（底脚、安全阀、轴承体）等组成，通过改变附件达到改变泵的不同安装形式。
3GBW系列保温螺杆泵主要用于在常温下不能输送的高粘度润滑体液体，常作为沥青、重燃油、渣油、原油的输送或喷燃用。热载体可以是蒸汽和热油、热水、冷载体可以是气体或液体。现广泛用于公路建设中沥青的输送。一般Z高工作温度小于等于250度；超出此温度订货时请说明。
3G、3GBW两种系列螺杆泵的外形、安装尺寸相同。

三螺杆泵原理
螺杆泵依靠螺杆相互啮合的容积变化来输送液体，当螺杆转动时，吸入腔一端的密封腔连续地向派出腔一端作轴向运动，使吸入腔的容积增大，压力降低，液体在压差作用下沿吸入管进入吸入腔，随着螺杆的转动，密封腔内的液体连续而均匀地沿轴向移至排出腔

三螺杆泵特点
结构简单，体积小、允许高转速、工作平稳可靠、压力脉动小、流量稳定、噪音小、效率高、有自吸能力、节能。

三螺杆泵使用范围
1、介质为直线连续输送、无搅拌、无脉动。
2、振动小，噪音低。
3、压力高、效率高。
4、结构简单、拆装方便。
5、体积小，重量轻。
6、磨损轻微，寿命长。
螺杆泵适用于输送燃料油、润滑油、液压油、植物油、沥青及其他润滑性液体和油、水、气混合液体。

Three screw pump overview:
The three screw pump is widely used in petroleum, chemical, metallurgy, machine tool, shipbuilding and other industries. And in many fields in place of the centrifugal pump, gear pump and reciprocating pump, the German Bach design and production of 3G, 3GBW, 3Gr screw pump has a long life, high efficiency, low energy consumption, light weight and other characteristics. 3G, 3Gr series three screw pump is mainly used for conveying low viscosity lubricating liquid. In industrial production as a hydraulic pump, lubricating pump, light fuel oil pump, pump. Pump components: pump body, pump sleeve, screw and accessories (foot, safety valve, bearing body) etc., through different forms of installation accessories to change to change the pump.
3GBW series thermal insulation screw pump is mainly used in the high temperature viscosity fluid can not be transported at room temperature, often used as asphalt, heavy fuel oil, residual oil, crude oil delivery or injection. The heat carrier can be steam and hot oil, hot water and cold carrier can be gas or liquid. It is widely used in the transportation of asphalt in highway construction. Generally the highest working temperature is less than or equal to 250 degrees.
3G, 3GBW two series screw pump configuration, the same size.
Three screw pump theory
Depending on the volume change of screw pump screw meshing to transport the liquid, when the rotation of the screw, one end of the suction seal cavity is continuously sent to end cavity for axial movement, the suction chamber volume increases, pressure is reduced, the liquid under pressure along the suction pipe into the suction chamber, with the rotation of the screw, the sealing cavity the liquid continuously and evenly along the axial direction to the discharge chamber
Three screw pump features
The utility model has the advantages of simple structure, small size, high rotating speed, stable and reliable operation, small pressure pulsation, stable flow rate, low noise, high efficiency, self absorption capacity and energy saving.
Three screw pump use range
1, the medium for linear continuous transmission, no mixing, no pulsation.
2, small vibration, low noise.
3, high pressure, high efficiency.
4, simple structure, easy disassembly.
5, small size, light weight.
6, mild wear, long life.
The screw pump is suitable for conveying fuel oil, lubricating oil, hydraulic oil, vegetable oil, asphalt and other lubricating liquid and oil, water and gas mixed liquid.
