4、材料：根据用户的实际需要，双吸泵的材料铸铁、304不锈钢、316不锈钢。
英国GRIMM格林进口卧式单级双吸离心泵结构说明：
1、泵的吸入口与吐出口均在水泵轴心线下方，水平方向与轴线成垂直位置、泵壳.中开，检修时无需拆卸进水，排出管路及电动机(或其他原动机)从联轴器向泵的方向看去，水泵均为逆吋针方向旋转。如根据用户特殊订货需要也可改为顺吋针旋转。
2、泵的主要零部件有：泵体、泵盖、叶轮、轴、双吸密封环、轴套、轴承等。除轴的材料为优质碳素钢外， 其馀多为铸铁制成。 泵体与泵盖构成叶轮的工作室，在进出水法兰上制有安装真空表和压力表的管螺孔，进出水法兰的下部制有放水的管螺孔。
3、 叶轮经过静平衡校验，用轴套和两侧的轴套螺母固定，其轴向位置可以通过轴套螺母进行调整，叶轮的轴向力利用其叶片的对称布置达到平衡，可能还有一些剩馀轴向力则同轴端的轴承承受。
4、 泵轴由两个单列向心球轴承支承，轴承装在泵体两端的轴承体内，用黄油润滑，双吸密封环用以减少水泵压水室的水漏回吸水室。
5、水泵通过联轴器由电动机直接传动。
6、 轴封为软填料密封，为了冷却润滑密封腔和防止空气漏入泵内，在填料之间有水封环，水泵工作时小量高压水通过水封管流入填料腔起水封作用。

UK GRIMM imported horizontal single stage double suction centrifugal pump summary:
imported horizontal single stage double suction centrifugal pump, single stage double suction pump shell, horizontal center open centrifugal pump. The temperature of the liquid to be transported shall not exceed 80 ℃ for the purpose of conveying clear water or other chemicals which are similar in physical and chemical properties to water. If both ends of the bearings pass through the cooling water, the medium temperature can reach 130 ℃. Change the impeller, sealing ring and shaft sleeve material, you can send sediment containing muddy water or all kinds of corrosive liquid. Pump shaft seal generally use soft packing, if special order requirements, can also be installed mechanical seal.
Compared with other pumps of the same type, the pump has the advantages of long service life, high efficiency, reasonable structure, low cost, convenient installation and maintenance, etc., and is an ideal pump for fire fighting, air conditioning, chemical, water treatment, ship and other industries. Widely used in factories, mines, urban water supply and drainage, power plants, irrigation and drainage of farmland and various water conservancy projects.
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.
