2、部件材质：
泵体、泵盖：铸铁、不锈钢
叶轮：硅黄铜(铝铁青铜)，铸铁(第二级)
密封环、轴套、衬套：耐磨zt诱导轮：铝铁青铜
轴：优质碳素钢
3、支承部分：
      三个品种支承部分结构相同，主要件有托架、前后轴承压盖和轴组合定位在托架上的前后径向滚珠铀承上，滚球铀承亦承受未被平衡的轴向力。用稀油润滑，油量可从油标看出。前后轴承压盖均装有毛毡密封圈做为轴封以防漏油。管堵处的孔用来灌油。清洗换油时从丝孔将油放出。
4、密封和传动：
      轴采用软填料密封，在轴封处装有可更换的轴套。
      泵通过弹性联铀器由电动机驱动。从传动方向看，泵为逆时针方向旋转。

UK GRIMM Inlet condensing pump summary:

           Imported condensate pumps, GRN and GRNB pumps are single stage single suction overhung centrifugal condensing pumps. GRGN, GRGNL series two stage single suction centrifugal condensate pump, suitable for power plant, pumping water from the condenser to condense and 750 ~ 3000kW turbine pumping liquid condensed water or other physical and chemical properties similar to water use. Liquid temperature is not more than 80 degrees centigrade. The pump inlet pressure is not higher than 1.6MPa.

        GRN condensate pump mainly by suspension, pump body, pump cover, impeller, pump shaft and other components. Seal adopts soft packing seal.

UK GRIMM Inlet condensing pump structure description:

 

1.Varieties:

   GRN condensate pump has horizontal suspension, single stage, two stage, single stage pulley and so on. There are 9 varieties. The single stage has GR3N6, GR4N6, GR100N130 and GR100N160; the two stage has GR2.5N3 * 2, GR3N6 * 2, GR4N6 * 2, and single stage induction wheels have GR6N6 and GR150N110.

2.Part material:

Pump body, pump cover: cast iron, stainless steel

Impeller: silicon, brass (aluminum, iron, bronze), cast iron (grade second)

Sealing rings, bushings and bushings: wear-resistant ZT inducer: aluminum, iron, bronze

Axle: high quality carbon steel

3.Support part:

   The supporting parts of the three varieties have the same structure. The main parts are a bracket, front and rear bearings, gland and shaft, which are positioned on the front and rear radial ball bearings of the bearing, and the ball bearing uranium bearing is also subjected to unbalanced axial forces. Lubrication with thin oil, the amount of oil can be seen from the oil mark. The front and rear bearing gland are all equipped with felt sealing ring as shaft seal to prevent oil leakage. A hole in a pipe that is used to fill oil. Remove oil from the wire hole when cleaning the oil.

4.Sealing and transmission:

   The shaft is made of soft packing, and replaceable shaft sleeve is installed at the shaft seal.

   The pump is driven by an electric motor by means of an elastic uranium connected device. Viewed from the drive, the pump rotates counter clockwise.

UK GRIMM Inlet condensing pump characteristic:

 

1.High suction performance, that is, with good cavitation performance.

2.The pump efficiency is high, there is a stable and smooth flow - uplift curve.
