英國GRIMM格林進口離心油泵 UK GRIMM Imported centrifugal oil pump

英國GRIMM格林進口離心油泵概述：
          進口離心油泵，是在英國格林老型油泵系列的基礎上進行改造并重新設計的,它是為滿足現代化建設的需要，盡快的適應以節能為中心的設備更新換代的新產品。

英國GRIMM格林進口離心油泵特點：
1、軸承體部件將原35、50、60軸承體分別用45、55、70軸承體，提高了可靠性； 
2、水利部分采用了高效節能的水利模型，平均效率比Y型油泵效率高5～8%； 
3、為保證繼承性，泵結構型式、外形安裝尺寸、性能范圍與老型油泵相同，便于老裝置更新改造； 
4、選材精煉，主題以Ⅱ、Ⅲ類材料為主，軸承體等零件增加為鑄鋼、鑄鐵兩種，為寒冷地區露天使用、船用提供了有力條件； 
5、零部件通用化程度高，標準件為幾個系列產品公用；軸承油空氣冷卻、風扇冷卻、水冷卻三種冷卻方式，根據泵送介質的不同溫度選用。其中風扇冷卻尤為適用于缺水或水質差的地區。 
英國GRIMM格林進口離心油泵結構特征： 
        進口離心油泵為徑向部分節段式結構，穿杠將吸入段、中段、吐出段連成一體。泵轉子由裝在軸上的葉輪、平衡盤（鼓）等零件組成。軸向力由平衡盤、平衡鼓和推力軸承平衡。
軸承：采用徑向滑動軸承或徑向球軸承，推力軸承采用向力推力球軸承，平衡殘余軸向力。
軸封：采用填料密封或機械密封，根據用戶需要而定。
傳動：泵通過柔性膜片聯軸器由原動機直接驅動，從原動機看泵為逆時針方向旋轉。

管路系統：冷卻水是根據介質溫度和使用要求，對軸封腔、軸承或泵支架等進行冷卻，水量每支管路建議為0.25-0.5m3/h，壓力為：0.25-0.3MPa。密封沖洗是根據泵輸送介質、溫度及壓力等工作條件不同而不同的。密封液的壓力一般要高于密封腔的壓力0.07-0.1MPa。若輸送介質屬于易汽化的，則應高于汽化壓力0.175-0.2MPa。蒸汽管路是當輸送介質的溫度降低而析出晶體時配備的，其壓力為0.1MPa左右。

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.
