Run Chuan lubricating oil pump, hydraulic pump, oil pump / Tianjin screw pump 3GR85*2W2
一、特点:
One, the characteristic:
三螺杆泵包括3G 3GR三螺杆泵通用型,3GC 船用三螺杆泵型及3GS三螺杆泵 3GCL三螺杆泵 3GCLS三螺杆泵等特殊型。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*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*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 3G 3GR three screw pump universal pump type and 3GS three screw, three screw pump 3GCL three screw pump3GCLS three screw pump and other special type of 3GC ship. Three screw pump's rotor type displacement pump, the driving screw and the driven screw spiral groove meshed with each other and they and the Bush inner surface with three holes, to form number level dynamic sealchamber between the import and export of the pump, the dynamic seal chamber will continue to put the liquid from the pump inlet to the pump outlet axial movement, and the the transfusion step, so as to form acontinuous, stable, the axial movement of the pressure of liquid.
二、适用介质及性能范围:
Two, suitable for medium range and performance:
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,*高工作压力100bar,*高温度150℃。
Three screw pumps transport liquid without solid particles, liquid lubricating oils and oil of similar non corrosive, lose liquid viscosity of 1.2~100 degree E (3.0~760cst), high viscosity liquids or viscosity by heating after the delivery. Flow range of 0.2~590m3/h, the maximum working pressure is 100bar, the maximum temperature of 150 degrees.
三、结构:
Three, structure:
3GR85*2
3GR85*2
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, the structure is simple: with a variety of structural form, usually a small flow of 0.2~6.5m3/h, 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 more than double suction structure made ofhorizontal installation, seal according to the different transmission mediaare 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 a horizontal and vertical two kinds,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*久性。
2, long service life: active screw and three screw pump driven by a motor,the Lord, have no mechanical contact from the pole, lost by the pressure of the liquid drives from the rod rotation around the axis line, the main,from between the rod and between the screw and bushing has a layer of oil film protection, so very small mechanical friction pump, life called 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, the transfusion liquid axial uniform linear motion in the pump, so the pressure 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 high suction capacity.
5、为*保*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
5, to ensure the pump, motor and pipeline system safety, traffic over the middle screw pump is provided with a safety valve when the pressure exceeds set pressure of safety valve, high pressure oil into the oil will flow back to pump

1、 严禁无介质空转,启动开车前请务必加入润滑性介质或输送介质。
2、 严禁一切杂物焊渣等进入泵腔内,务必保持泵腔和管道内部的清洁度。
3、 严禁使用管道过滤器或Y型过滤器装置,配置过滤器请*保*过滤面积是泵进口通径截面积的20-30倍。并依据介质的清洁度正确配置过滤网的目数。
4、 严禁泵的进出口管道与泵的进出口管道不匹配,管道通径配置必须和泵的进出口通径一致。以免发生汽蚀或无法自吸。管道过细必定导致汽蚀,从而使泵处于吃不饱的状态下工作,导致三螺杆泵组流量压力下降甚至是异常的振动和噪音,长时间运行还将导致卡泵和螺杆泵的严重损坏,
5、 三螺杆泵的安装高度必须充分考虑泵的汽蚀条件和泵的自吸能力(汽蚀余量与介质粘度转速和螺杆的导程有关)
6、 由于包装 运输 起吊 装卸以及管道螺栓紧固的作用可能易使泵的原出厂定位产生变化甚至严重错位,所以三螺杆泵组管系配置安装固定完毕后,一定要在启动开车之前重新检查三螺杆泵和电机的同轴度。
7、 严禁背压启动开机和关闭进口出口阀门的情况下启动开机。
8、 严禁不符合泵旋转标识的方向启动旋转。
9、 双泵并联必须在泵的出口和进口加单向阀,以防止介质倒流驱动三螺杆泵反转。
10、严禁随意调整安全阀螺栓。安全阀仅作为保护泵的安全和电机功率与泵工作状态的匹配,严禁作为调压阀和溢流阀使用。
