    进口离心油泵.jpg

    英国GRIMM格林进口离心油泵概述:
              进口离心油泵,是在英国格林老型油泵系列的基础上进行改造并重新设计的,它是为满足现代化建设的需要,尽快的适应以节能为中心的设备更新换代的新产品。

    英国GRIMM格林进口离心油泵特点:
    1、轴承体部件将原35、50、60轴承体分别用45、55、70轴承体,提高了可靠性; 
    2、水利部分采用了高效节能的水利模型,平均效率比Y型油泵效率高5~8%; 
    3、为保证继承性,泵结构型式、外形安装尺寸、性能范围与老型油泵相同,便于老装置更新改造; 
    4、选材精炼,主题以Ⅱ、Ⅲ类材料为主,轴承体等零件增加为铸钢、铸铁两种,为寒冷地区露天使用、船用提供了有力条件; 
    5、零部件通用化程度高,标准件为几个系列产品公用;轴承油空气冷却、风扇冷却、水冷却三种冷却方式,根据泵送介质的不同温度选用。其中风扇冷却尤为适用于缺水或水质差的地区。 

    英国GRIMM格林进口离心油泵结构特征: 
             进口离心油泵为径向部分节段式结构,穿杠将吸入段、中段、吐出段连成一体。泵转子由装在轴上的叶轮、平衡盘(鼓)等零件组成。轴向力由平衡盘、平衡鼓和推力轴承平衡。
    轴承:采用径向滑动轴承或径向球轴承,推力轴承采用向力推力球轴承,平衡残余轴向力。
    轴封:采用填料密封或机械密封,根据用户需要而定。
    传动:泵通过柔性膜片联轴器由原动机直接驱动,从原动机看泵为逆时针方向旋转。

    管路系统:冷却水是根据介质温度和使用要求,对轴封腔、轴承或泵支架等进行冷却,水量每支管路建议为0.25-0.5m3/h,压力为:0.25-0.3MPa。密封冲洗是根据泵输送介质、温度及压力等工作条件不同而不同的。密封液的压力一般要高于密封腔的压力0.07-0.1MPa。若输送介质属于易汽化的,则应高于汽化压力0.175-0.2MPa。蒸汽管路是当输送介质的温度降低而析出晶体时配备的,其压力为0.1MPa左右。

    英国GRIMM格林进口离心油泵主要参数:
    流       量:6.25-155m3/h
    扬       程:70-603m

    功       率:5.5-400kw
    转       速:2950r/min
    口       径:40-300mm
    工作温度:-20℃~+300℃
    工作压力:1.6-7.5Mpa
    材       质:铸铁、铸钢、不锈钢

    英国GRIMM格林进口离心油泵适用范围:
      主要可用在石油精制、石油化工和化学工业及其他地方输送不含固体颗粒的石油、液化石油气等介质,泵壳径向部分,特别适用于输送高温高压以及易燃、易爆或有毒的液体。

    UK GRIMM imported centrifugal oil pump summary:

            The import of the centrifugal pump, based on a British Green old type oil pump series and re design, it is to meet the needs of modernization, adapt to the new product update to the center for the energy-saving equipment.

    UK GRIMM imported centrifugal oil pump characteristic:

    1.The bearing body parts will be the original 35, 50 and 60 bearing bodies with 45, 55, 70 bearings, respectively, to improve reliability;

    2.The water conservancy part uses the energy saving water conservancy model, the average efficiency is higher than the Y type oil pump efficiency 5 to 8%;

    3.In order to ensure the inheritance, the pump structure, shape, installation size and performance range are the same as those of the old type oil pump, so that the old equipment can be renewed and transformed;

    4.Material selection, refining, the main theme of the class II, III class materials, bearings and other parts increased to cast steel, cast iron two kinds, for cold areas for outdoor use, ship provides a powerful condition;

    5.High degree of commonality of parts and components, standard parts for several series of products common, bearing oil, air cooling, fan cooling, water cooling three cooling methods, according to the temperature of the pump medium selection. Among them, fan cooling is especially suitable for water shortage or poor water quality areas.

    UK GRIMM imported centrifugal oil pump structure characteristics:

             The inlet centrifugal pump is a radial part of the segmental structure, and the rod is connected with the suction section, the middle section and the spit section. The rotor of the pump consists of impeller, balance disc (drum) installed on the shaft. The axial force is balanced by the balance disc, balance drum and thrust bearing.

    Bearings: radial sliding bearings or radial ball bearings. Thrust bearings adopt thrust thrust ball bearings to balance the residual axial forces.

    Shaft seal: use packing seal or mechanical seal, according to the user's needs.

    Transmission: the pump is driven directly by the prime mover through a flexible diaphragm coupling, and the pump rotates counterclockwise as viewed from the prime mover.

    Pipeline system: cooling water is based on the medium temperature and the use of requirements, the shaft seal cavity, bearing or pump support, such as cooling, water quantity of each pipeline is recommended as 0.25-0.5m3/h, the pressure is: 0.25-0.3MPa. Sealing flushing is based on the pump medium, temperature and pressure and other working conditions vary. The pressure of the sealing liquid is generally higher than the pressure of the sealing chamber 0.07-0.1MPa. If the transport medium is easy to vaporize, it should be higher than the vaporization pressure 0.175-0.2MPa. The steam pipe is equipped when the temperature of the conveying medium is reduced and the pressure is about 0.1MPa.

    UK GRIMM imported centrifugal oil pump technical parameter:

    Flow rate: 6.25-155m3/h

    Lift: 70-603m

    Power: 5.5-400kw

    Speed: 2950r/min

    Caliber: 40-150mm

    Operating temperature: -20 DEG C to +300 C

    Working pressure: 1.6-10.0Mpa

    Material: cast iron, cast steel, stainless steel

    UK GRIMM imported centrifugal oil pump scope of application:

            Mainly used in petroleum refining, petrochemical and chemical industries and other local delivery of solid particles in oil and liquefied petroleum gas medium, the pump shell radial part, especially suitable for high temperature and high pressure and transport of flammable, explosive or toxic liquid.
