3GR三螺杆泵详细内容
3GR三螺杆泵用来输送温度≤150℃、粘度3-760cst,三螺杆泵不含固体颗粒、无腐蚀性、具有润滑性能的介质。3GR三螺杆泵主要应用于燃油输送、液压工程机械业及重型机械业、3GR三螺杆泵船舶及海上工程、油罐及印染工业、化工、石化及其它工业。 3GR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1.2-100E(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—590m /h,zui高工作压力100bar,zui高温度150℃。 三螺杆泵结构简单:具有多种结构形式,三螺杆泵一般小流量0.2—6.5m/h,泵的泵体和衬套合为一个(统称泵体)轴封为端面机械密封。 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端面机械密封和填料密封两种。 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。寿命长,3GR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悍绕轴心线自转,主,从杆之间、螺杆与衬套之间皆有一层油膜保护,因而3GR三螺杆泵的机械摩擦极小,寿命堪称半*性。所输液体在3GR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,由于转动部分惯性小,则起动力矩和振动很小。3GR三螺杆泵具有高吸入能力,3GR三螺杆泵,电机及管路系统的安全,中等流量以上的螺悍泵均带有安全阀,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。
3GR螺杆泵工作原理与特点
3GR screw pump working principle and characteristics
3GR螺杆泵是利用螺杆的回转来吸排液体的。主、从动螺杆的螺纹均为双头螺纹。由于各螺杆的相互啮合以及螺杆与衬筒内壁的紧密配合,在泵的吸入口和排出口之间,就会被分隔成一个或多个密封空间。随着螺杆的转动和啮合,这些密封空间在泵的吸入端不断形成,将吸入室中的液体封入其中,并自吸入室沿螺杆轴向连续地推移至排出端,将封闭在各空间中的液体不断排出,犹如一螺母在螺纹回转时被不断向前推进的情形那样,这就是3GR螺杆泵的基本工作原理。
3GR screw pump is used to suck the liquid rotary screw. The main, driven screw threads are double headed screw. Due to the mutual engagement of the screw and the screw and tube wall lining closely with, the pump suction port and exhaust port, will be separated into one ormore of the sealed space. With the rotating screw and meshing, the sealed space in the pump suction side evolving, the suction chamber of liquid filled therein, and a suction chamber along the screw axis continuous passage to the discharge end, will be closed in thespace continuous discharge of liquid, like a nut in screw rotation is constantly moving forwardthis is the case3GR the basic principle of the screw pump.
从上述工作原理可以看出,3GR螺杆泵有以下优点:
Can be seen from the above works, 3GR screw pump has the following advantages:
1)压力和流量范围宽阔。压力约在3.4-340千克力/cm2,流量可达18600cm3/分;
1) a wide range of pressure and flow. Pressure of about 3.4-340 KGF /cm2, flow up to 18600cm3/ min;
2)运送液体的种类和粘度范围宽广;
2) the delivery of liquid type and a wide range of viscosity;
3)因为泵内的回转部件惯性力较低,故可使用很高的转速;
3) because of the rotary inertia force components in the pump is low, it can use very high speed;
4)吸入性能好,具有自吸能力;
4) inhalation of good performance, with self absorption capacity;
5)流量均匀连续,振动小,噪音低;
5) continuous uniform flow, small vibration, low noise;
6)与其它回转泵相比,对进入的气体和污物不太敏感;
6) when compared with other rotary pump, less sensitive to gas and dirt entering the;
7)结构坚实,安装保养容易。
7) the structure of a solid, easy installation and maintenance.
3GR螺杆泵的缺点是,螺杆的加工和装配要求较高;泵的性能对液体的粘度变化比较敏感。
尽管三3GR螺杆泵有诸多优势,但若选型不当,则不仅得不到满意的运行效果,而且会导致泵的噪音和振动,甚至严重损坏泵的内部零件,使泵系统 不能正常工作,因此,选型人员应多方慎重考虑,合理选型 ,必要时应向我公司技术部门咨询。三3GR螺杆泵选型时,要尽可能详尽地了解泵的使用条件,除了运行参数,如流量 ,压力需要清楚以外,输送介质的特性如介质的腐蚀性,含汽量,含固溶物的比率及固体颗粒的大小,以及介质的工作温度,粘度,比重,对材料的腐蚀性等和泵装置的吸入条件,安装条件均要了解,根据我们的经验,
3GR the disadvantage is that the screw pump, screw machining and assembly demanding;more sensitive to the change of fluid viscosity pump performance
Although the three 3GR screw pump has many advantages, but if the improper selection, not only not to run a satisfying effect, but will lead to the vibration and noise of pump, or even seriously damage the internal parts of the pump, the pump system can not work normally,therefore, selection should be more party carefully consideration, reasonable selection, when necessary should consult technical service department of our company. Three 3GR screwpump selection, to be as detailed as possible understanding of the pump operating conditions, in addition to operating parameters, such as flow rate, pressure needs to beclear, the conveying medium properties such as corrosive medium, steam content, containingsolids and the ratio of the size of the solid particles, and the operating temperature, the viscosity of the medium, specific gravity, suction conditions on corrosion resistance and pump device materials, installation conditions are to understand, according to our experience
三、3GR螺杆泵选型 时应注意以下几点:
3GR screw pump selection should pay attention to the following points:
1. 泵转速的选择
1 pump speed selection
1.1 以输送介质粘度和泵的规格确定转速范围:
1.1 to the transmission medium viscosity and pump specifications to determine the speed range:
输送高粘度介质时,泵应选低转速,若粘度较低,相应可选择高转速:介质粘度〉 20°E 时,对于大规格的泵(主杆外径60mm 以上),转速以970rpm 或720rpm 为宜,如果粘度更高(粘度>80°E )如粘胶液,可降低转速使用,* 200-500rpm ;
The transport of high viscosity medium, the pump should be selected the low speed, if theviscosity is low, the corresponding choice of high speed: medium viscosity '20 ° E, thespecifications of the pump (above the main rod diameter 60mm), the speed with 970rpm or720rpm is appropriate, if higher viscosity (viscosity >80 ° E) such as viscose reduce speed,can use, recommended 200-500rpm;
对于小规格的泵,介质粘度>20°E 时,转速以1450rpm 或970rpm 为宜,如果粘度更高(粘度>80°E ),可降低转速使用,*300-600rpm ;
For the small size of the pump, medium viscosity >20 ° E, speed to 1450rpm or 970rpm is appropriate, if higher viscosity (viscosity >80 ° E), can reduce speed to use, recommended 300-600rpm;
1.2 由于泵的转速越高,在相同性能参数下,泵的体积就越小,但由于转速高,摩擦功率高,泵的磨损就大,寿命就短,如果输送介质的润滑性比较差或含有微量杂质,应选择较低转速,以使泵保持较长的寿命,*在1450rpm 以下。
1.2 because of the higher speed of the pump, in the same performance parameters, the smaller size of the pump, but because of high speed, high power pump friction, wear and tear on the big, short life, if the transmission medium relatively poor lubrication or contain trace impurities, should choose low speed, so that the pump to maintain the longer life, recommendbelow 1450rpm
2. 结构的选择可根据泵的安装和使用条件参3GR螺杆泵的系列和型式来进行,原则上:
2 structure can choose according to installation of the pump and the use of reference condition three 3GR screw pump series and types are, in principle
2.1 输送润滑性油类,温度在80°C 以下选择内置结构的泵;
A 2.1 conveying lubricating oils, choice of internal structure of pump temperature below 80 ° C;
2.2 温度超过80°C 或输送介质润滑性差时,选择外置 轴承 结构的泵;
2.2 temperature exceeds 80 ° C or conveying medium poor lubrication, select the external bearing structure of pump;
2.3 输送流动性差,粘度较高的介质或需要所输送介质进行加热或保温时选择双层加热泵体结构的泵;
2.3 the transport mobility is poor, medium or high viscosity media transport needs of theselection of heating or insulation layer structure of heat pump pump;
2.4 高温输送时,应选择耐高温的材料所制成的泵,请与我厂。
2.4 high temperature pipeline, should choose the high temperature resistant material pump,please contact with my factory.
3. 泵材料组合的选择:
