3GR三螺杆泵概述简介
特点:
三螺杆泵包括3G 通用型,3GC 船用型及特殊型。三螺杆泵是转子式容积泵,由于主动螺杆与从动螺杆上螺旋槽相互啮合及它们与衬套三孔内表面的配合,得以在泵的进出口之间形成数级动密封腔室,这些动密封腔室将不断把液体由泵进口轴向移动到泵出口,并使所输液体逐级升压,从而形成一个连续、平稳、轴向移动的压力液体。
适用介质及性能范围:
三螺杆泵所输液体为各种不含固体颗粒,无腐蚀性油类及类似油的润滑性液体,所输液体粘度为1.2~100°E(3.0~760cst),高粘度液体亦可通过加温降粘后输送。流量范围0.2~590m3/h,工作压力100bar,温度150℃。

Three screw pump includes 3G 3GR three screw pump universal pump, 3GS three screw pump, three screw 3GCL 3GCLS three screw pump three screw pump and other special type of 3GC ship. Three screw pump is a rotary positive displacement pump, the driving screw and screw driven spiral grooveengagement between them and bushing hole and the inner surface of the cooperation, to form number level dynamic seal chamber between the import and export of the pump, the dynamic seal chamber will continue to bring the liquid from the pump inlet to the outlet of the pumpaxial movement, and the transport liquid step, so as to form a continuous, stable,axial movement of the preure of liquid.
二、适用介质及性能范围:
Two, applicable range and performance of medium:
三螺杆泵所输液体为各种不含固体颗粒,无腐蚀性油类及类似油的润滑性液体,所输液体粘度为1.2~100°E(3.0~760cst),高粘度液体亦可通过加温降粘后输送。流量范围0.2~590m3/h,工作压力100bar,温度150℃。
Three screw pump transport liquid not containing solid particles, liquid lubricating oil and similar non corrosive oil and transport liquid viscosity of 1.2~100 E (3.0~760cst),high viscosity or viscosity by heating after delivery. The flow range of 0.2~590m3/h,the maximum working preure 100bar, the maximum temperature of 150 degrees.
三、结构:
Three, structure:
1、结构简单:具有多种结构形式,一般小流量0.2~6.5m3/h,泵的泵体和衬套合为一体(统称泵体),轴封为机械密封。
1, has the advantages of simple structure: with a variety of structural forms, general small flow rate 0.2~6.5m3/h, the pump body and the liner into one (collectively referred to as the pump), seal mechanical seal.
中等流量以上的泵衬套为一单独的零件固定于泵体内,大流量泵多制成双吸结构卧式安装,轴封根据输送介质的不同有机械密封和填料密封两种。
Medium flow above for a single pump bushing fixed in the pump body parts, large flow pump double suction structure made of horizontal installation, seal according to the different transmiion media are two kinds of mechanical seals and packing seal.
船用泵的安装形式有卧式和立式两种,原动机为交、直流船用电动机。
Marine pump installed in the form of two horizontal and vertical, the original motivation for the AC and DC motor ship.
2、寿命长:三螺杆泵的主动螺杆由电动机驱动,主、从杆之间没有机械接触,而由所输压力液体驱使从杆绕轴心线自转,主、从杆之间、螺杆与衬套之间皆有一层油膜保护,因而泵的机械摩擦极小,寿命堪称半性。
2, long service life: the active screw and three screw pump driven by a motor, andthere is no mechanical contact between the rod and lost by the preure of the liquidfrom the rod drives the rotation around the axis line, and from between the rod andscrew and bushing is a layer of oil film protection, so very small mechanical friction pump life. A semi permanent.
3、所输液体在泵内作轴向匀速直线运动,故压力脉动小,流量稳定,噪音低,由于转动部件惯性小,则起动力矩和振动很小。
3, lose liquid axial uniform linear motion in the pump, so the preure fluctuation is small, the flow stability, low noise, due to the inertia of rotating parts is small, the starting torque and vibration is small.
4、具有高吸入能力。
4, with a high suction capacity.
5、为保证泵,电机及管路系统的安全,中等流量以上的螺杆泵均带有安全阀当压力超过安全阀的设定压力时,高压油将回流至泵的进油口。
5, to ensure that the pump, motor and pipeline system safety, traffic over the middlescrew pump is provided with a safety valve when the preure exceeds the setpreure of safety valve, high preure oil into the oil will flow back to pump outlet.
