英國(guó)GRIMM格林進(jìn)口臥式單級(jí)雙吸離心泵特點(diǎn)：

             進(jìn)口臥式單級(jí)雙吸泵與其它同類型的泵相比較具有壽命長(zhǎng)、效率高、結(jié)構(gòu)合理，運(yùn)行成本低、安裝及維修方便等特點(diǎn)，是消防、空調(diào)、化工、水處理及其它行業(yè)的理想用泵。泵體的設(shè)計(jì)壓力為1.6MPa和2.0MPa。為滿足世界范圍用戶的不同要求，相應(yīng)的泵體進(jìn)出口法蘭可按ANSI、PN及IS等標(biāo)準(zhǔn)選取。泵體的進(jìn)出口法蘭均位于下泵體，這樣可以在不拆卸系統(tǒng)管路的情況下取出轉(zhuǎn)子，維修方便部分泵體采用雙流道設(shè)計(jì)，以減少?gòu)较蛄Γ瑥亩娱L(zhǎng)機(jī)封和軸承的壽命。

1、葉輪：葉輪的水力設(shè)計(jì)采用了zui先進(jìn)的CFD技術(shù)，因此提高了雙吸泵的水力效率。對(duì)葉輪進(jìn)行動(dòng)平衡，確保泵的運(yùn)行平穩(wěn)。

2、軸：軸徑較粗，軸承間距較短，從而減小了軸的撓度，延長(zhǎng)了機(jī)械密封和軸承的壽命。軸套可以采用多種不同的材料，以防止軸被腐蝕和磨損，軸套可更換。磨損環(huán)泵體與葉輪間采用可更換的磨損環(huán)，防止泵體和葉輪的磨損，更換方便，維修費(fèi)用低，同時(shí)保證運(yùn)行間隙和較高的工作效率。既可以使用填料也可以使用機(jī)械密封，可以在不拆卸泵蓋的情況下更換密封裝置。

3、軸承：獨(dú)特的軸承體設(shè)計(jì)使軸承可采用油脂或稀油潤(rùn)滑，軸承的設(shè)計(jì)壽命10萬(wàn)小時(shí)以上，也可使用雙列推力軸承和封閉軸承。

4、材料：根據(jù)用戶的實(shí)際需要，雙吸泵的材料鑄鐵、304不銹鋼、316不銹鋼。

英國(guó)GRIMM格林進(jìn)口臥式單級(jí)雙吸離心泵結(jié)構(gòu)說(shuō)明：

1、泵的吸入口與吐出口均在水泵軸心線下方，水平方向與軸線成垂直位置、泵殼.中開(kāi)，檢修時(shí)無(wú)需拆卸進(jìn)水，排出管路及電動(dòng)機(jī)(或其他原動(dòng)機(jī))從聯(lián)軸器向泵的方向看去，水泵均為逆吋針?lè)较蛐D(zhuǎn)。如根據(jù)用戶特殊訂貨需要也可改為順吋針旋轉(zhuǎn)。

2、泵的主要零部件有：泵體、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套、軸承等。除軸的材料為優(yōu)質(zhì)碳素鋼外， 其馀多為鑄鐵制成。 泵體與泵蓋構(gòu)成葉輪的工作室，在進(jìn)出水法蘭上制有安裝真空表和壓力表的管螺孔，進(jìn)出水法蘭的下部制有放水的管螺孔。

3、 葉輪經(jīng)過(guò)靜平衡校驗(yàn)，用軸套和兩側(cè)的軸套螺母固定，其軸向位置可以通過(guò)軸套螺母進(jìn)行調(diào)整，葉輪的軸向力利用其葉片的對(duì)稱布置達(dá)到平衡，可能還有一些剩馀軸向力則同軸端的軸承承受。

4、 泵軸由兩個(gè)單列向心球軸承支承，軸承裝在泵體兩端的軸承體內(nèi)，用黃油潤(rùn)滑，雙吸密封環(huán)用以減少水泵壓水室的水漏回吸水室。

5、水泵通過(guò)聯(lián)軸器由電動(dòng)機(jī)直接傳動(dòng)。

6、 軸封為軟填料密封，為了冷卻潤(rùn)滑密封腔和防止空氣漏入泵內(nèi)，在填料之間有水封環(huán)，水泵工作時(shí)小量高壓水通過(guò)水封管流入填料腔起水封作用。

UK GRIMM imported horizontal single stage double suction centrifugal pump characteristic:

           The imported Horizontal single-stage double suction pump and other pump has long service life, high efficiency, reasonable structure, advantages of low operation cost, convenient installation and maintenance, fire, air conditioning, water treatment, chemical and other industries the ideal pump. The design pressure of pump body is 1.6MPa and 2.0MPa. In order to meet the different requirements of users worldwide, the corresponding inlet and outlet flanges for pumps can be selected according to the standards of ANSI, PN and IS. The pump inlet and outlet flange are located in the pump body, it can be removed without dismantling the rotor of the pipeline system case, convenient maintenance part of the pump body adopts the double channel design, to reduce the radial force, so as to prolong the lifetime of bearing and sealing machine.

1.Impeller: impeller hydraulic design using the most advanced CFD technology, so as to improve the hydraulic efficiency of double suction pump. Balance the action of the impeller to ensure the smooth running of the pump.

2.Axle: the axle diameter is thick, the bearing spacing is short, thus reduced the axle deflection, has extended the mechanical seal and the bearing life. Bushings can be made of a wide variety of materials to prevent corrosion and wear of the shaft, and the bushing can be replaced. Wear rings can be used between the pump body and the impeller of the wear ring to prevent the abrasion of the pump body and the impeller. The utility model has the advantages of convenient replacement and low maintenance cost, and simultaneously ensures the running clearance and the higher work efficiency. Either a filler or a mechanical seal can be used to replace the seal without removing the pump cover.

3.Bearings: unique bearing body design, so that bearings can be grease or thin oil lubrication, bearing design life of more than 100 thousand hours, can also use double thrust bearings and closed bearings.

4.Material: according to the actual needs of users, double suction pump material, cast iron, 304 stainless steel, 316 stainless steel.

UK GRIMM imported horizontal single stage double suction centrifugal pump structure description:

1.The pump inlet and outlet are in the pump axis below the horizontal axis and vertical position, the pump shell. In the open, it is unnecessary to remove the water discharge pipe and a motor (or other prime movers) to see from the coupling to the pump, pump are inverse to the needle. Rotation. In accordance with the user's special order requirements, can also be changed to inch needle rotation.

2.Pump main components are: pump body, pump cover, impeller, shaft, double suction sealing ring, shaft sleeve, bearings and so on. The shafts are made of high quality carbon steel, and the remainder are made of cast iron. The pump body and the pump cover form the working chamber of the impeller, and the screw holes for installing the vacuum meter and the pressure gauge are arranged on the water inlet and the water outlet flange, and the lower part of the inlet and outlet water flanges is provided with a water outlet pipe hole.

3.The impeller is static balanced, fixed by the sleeve and the sleeve nuts on both sides. Its axial position can be adjusted through the sleeve nut, the axial force of the impeller with the symmetrical arrangement of its blades to achieve balance, there may be some residual bearing axial force which is coaxial end bearing.

4.The pump shaft is composed of two single row radial ball bearing, bearings mounted in the bearing body at both ends of the pump body, with lubrication, double suction to reduce the water pressure water chamber drain back to the suction chamber sealing ring.

5.The water pump is directly driven by the motor through the coupling.

6.The shaft seal is a soft packing seal, in order to cool, lubricate the sealing cavity and prevent leakage of air into the pump, there is a water seal between the packings. When the pump works, a small amount of high-pressure water flows through the water seal pipe into the packing chamber and acts as a water seal.
