英國GRIMM格林進口自吸泵 UK GRIMM Imported self-priming pump

英國GRIMM格林進口自吸泵概述： 

          進口自吸泵是根據英國格林有關技術資料經吸收、消化、改進后研制而成的節能泵類產品。該泵屬自吸式離心泵，它具有結構緊湊、操作方便、運行平穩、維護容易、效率高、壽命長、并有較強的自吸能力等優點。管路中不需安裝底閥，工作前只需保留泵體內儲有定量引液即可。因此簡化了管路系統，又改善了勞動條件。

英國GRIMM格林進口自吸泵結構說明及工作原理： 

             進口自吸泵，主要由泵體、葉輪后蓋、機械密封、泵軸、軸承座、進口閥、氣液分離管、加水閥門，進、排接管等 組成。
          泵的工作原理，該泵均采用軸向回液的泵體。原理由吸入室、儲液室、渦卷室、回液孔、氣液分離室等組成。
          泵正常起動后，葉輪將吸入室所存的液體及吸入管路中的空氣一起吸入，并在葉輪內得以完全混合，在離心力的作用下，液體夾帶著氣體向渦卷室外緣流動，在葉輪的外緣上形成有一定厚度的白色泡沫帶及高速旋轉液環。氣液混合體通過擴散管進入氣液分離室。此時，由于流速突然降低，較輕的氣體從混合氣液中被分離出來，氣體通過泵體吐出口繼續上升排出。脫氣后的液體回到儲液室，并由回流孔再次進入葉輪，與葉輪內部從吸入管路中吸入的氣體再次混合，在高速旋轉的葉輪作用下，又流向葉輪外緣??????。隨著這個過程周而復始的進行下去，吸入管路中的空氣不斷減少，直到吸盡氣體，完成自吸過程，泵便投入正常作業。

UK GRIMM Imported self-priming pump summary:

         Imported self-priming pump is based on the relevant technical data of the United Kingdom Green, absorbed, digested, improved, developed from energy-saving pump products. The pump is a self suction centrifugal pump. It has the advantages of compact structure, easy operation, stable operation, easy maintenance, high efficiency, long service life and strong self suction capacity. Do not need to install the valve in the pipeline, keep working just before the pump body fluid can be stored with quantitative cited. Therefore, the pipeline system is simplified and the working conditions are improved.

UK GRIMM Imported self-priming pump structure description and working principle:

           Imported self-priming pump, mainly by pump body, impeller rear cover, mechanical seal, pump shaft, bearing seat, inlet valve, gas-liquid separation pipe, water valve, intake, discharge pipe and so on.

        The working principle of the pump is that the pump adopts axial return liquid pump. The principle is composed of suction chamber, liquid storage room, scroll chamber, liquid return hole, gas-liquid separation chamber and so on.

        Pump normal starting, the impeller room will suck the liquid suction pipe and the air suction, and can be fully mixed in the impeller under the action of centrifugal force, the liquid entrainment from the gas chamber outer scroll flow, the formation of a certain thickness of the white foam and high-speed liquid ring in the impeller on the edge. The gas-liquid mixture passes through the diffusion tube into the gas-liquid separation chamber. At this point, as the flow rate suddenly decreases, the lighter gas is separated from the mixture gas, and the gas continues to rise and discharge through the pump body. After the degassing of liquid to the liquid storage chamber, and the reflux hole again into the gas and the impeller, impeller sucked from the suction pipe again mixed in high speed rotating impeller role, and flows to the outer edge of the impeller feels feels feels feels feels feels. As the process goes on and on, the air in the suction line continues to decrease until the gas is exhausted and the self-priming process is completed, and the pump is put into normal operation.
