●特点：
3G三螺杆泵包括3G
通用型，3GC船用型及特殊型。3G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。Three-screw
pump including 3 g, 3 g for general 3 gc Marine type and special type.3 g
three screw pump is a positive displacement pump rotor type, due to the
driving screw and driven screw spiral groove on the pitch and they
cooperate with three hole on the surface of the liner, in between the
import and export of the pump Form number level dynamic seal chamber, the
dynamic seal chamber will continue to move from pump axial liquid pump
discharge, and lose a liquid booster step by step, thus forming a
continuous, smooth, axial movement of liquid pressure.
●3G三螺杆泵适用介质及性能范围：3 g three-screw pump applicable medium range and
performance
3G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，黄山铁人三螺杆泵工作压力100bar，黄山铁人三螺杆泵温度150℃。3
g three-screw pump of liquid for various not containing solid particles,
non-corrosive oil lubricity and similar oil liquid, the liquid viscosity
is 1.2 ~ 100 ° E (3.0 ~ 760 CST), high viscosity liquid can be transmitted
through heating after the viscosity.Flow range of 0.2 ~ 590 m3 / h,
maximum working pressure of 100 bar, the highest temperature of 150 ℃.
●3G三螺杆泵结构:
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。Simple
structure: has a variety of structural form, generally small flow of 0.2 ~
6.5 m3 / h, pump body and pump bushing (generally referred to as the pump
body), is an organic whole to shaft seal for the 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 the pump sleeve is fixed in a separate pump body, big flow made
double suction pump more structure horizontal installation, depending on
the medium of the shaft sealing has two kinds of mechanical seals and
packing seal.
3G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。3 g Marine pump installations have
horizontal and vertical two kinds, prime mover for Marine ac or dc motor.
2、寿长：3G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，寿堪称半黄山铁人三螺杆泵性。Long
life: 3 g three-screw pump active screw driven by a motor, no mechanical
contact between master and slave rod, and by a liquid pressure driven from
rod rotated on its axis, the Lord, from between rod, screw and bushing is
a layer of oil film protection, thus pump mechanical friction small, life
is a permanent.
3、所输液体在3G三螺杆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。
4、3G三螺杆泵具有高吸入能力。Of liquid in a 3 g three-screw pump axial uniform motion
in a straight line, so the pressure fluctuation is small, flow stability,
low noise, due to the small inertia rotating parts, starting torque and
small vibration.
5、为保证3G三螺杆泵、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。In
order to ensure the 3 g three screw pump, motor and the safety of the
pipeline system, secondary flow above the screw pump is with safety valve,
when pressure exceeds the set pressure of the relief valve, high pressure
oil will flow back to the inlet of the pump.
