英國GRIMM格林進口立式軸流泵結構說明：br>

進口立式軸流泵主要由水泵本體部分和傳動部分所組成。

1、水泵本體部分：

泵軸采用優質碳素鋼制成，它籍上下兩只橡膠(或塑料)軸承來支撐。運轉過程中，提供了用來潤滑軸承的良好條件，泵軸上端的一只軸承，因多半高出水面，所以在填料函(或密封蓋)上裝一短管，提供啟動前灌輸清水潤滑該軸承之用(待啟動出水后，灌水即可停止)。軸承頸部是一優質碳素鋼的軸套，表面涂有硬鉻，以提高耐磨性和抗蝕性。其它主要零件如：喇叭管、葉輪座、葉輪外殼、導葉體、軸承座、填料座和聯軸器等均用鑄鐵制造，出水彎管為鋼焊件。填料裝有填料，以提高泵的密封性。

水泵葉輪的轉向，從吸入口看，為逆時針方向(從上向下看為順時針方向)。水泵的葉輪外殼(或連于導葉體、進水喇叭上)與葉輪兩相鄰表面，均呈球形面，這樣保證了葉片在任何安裝角度時，葉輪外圓與葉輪外殼之間有很小的間隙，以減少回流水量損失。

根據使用需要，該型水泵可按：“工作性能表”增速或降速使用或調節葉片的安裝角度，變更流量及揚程，擴大使用范圍。葉片采用優質球鐵制造，葉輪均經靜平衡校正出廠。葉片用葉片螺母(或葉片緊圈)緊固于葉輪座上，葉片與葉輪座相鄰表面刻有角度線。水泵出廠時，葉片之安裝角度一般為“零”度，用戶可根據需要，按照工作性能表自行調整葉片安裝角度。安裝前，用戶必須將葉片螺母重新緊固一次，以防松動而發生事故。

2、水泵傳動部分：

根據各地區的動力情況及用戶使用需要，在訂貨時應確定傳動方式，立式軸流式水泵的傳動有三種方法。

（1）立式電機直接傳動裝置：

電動機借螺栓緊固于電機座上，傳動軸一端借尼龍柱肖聯軸器與電動機聯接，另一端用剛性聯軸器與水泵聯接，傳動軸系優質碳素鋼制成，其它零件如電機座、軸承盒、軸承蓋底座等均用鑄鐵制成。水泵在運轉時，其全部軸向力(即水泵葉輪上的水壓力和全部水泵轉子重量之總和)均由電機座(或軸承座)內裝的軸承來承受。水泵轉子的軸向位移可借傳動裝置內的螺母來調整，這樣就使整個水泵機組簡化，安裝維修方便可靠。

（2）立式電機三角皮帶傳動裝置：

立式電機用螺栓緊固于機架上，機架緊固于導軌上，通過螺栓使機架能在導軌上滑動，以調整皮帶松緊。運轉過程中的徑向力，由皮帶輪及電機上的徑向軸承承受。

（3）立式半交叉平皮帶傳動：

皮帶輪以鑄鐵制造，固定在軸承座與螺母間而安裝在傳動軸上,傳動軸的徑向力和水泵傳動零件的重量和運轉的軸向力等均由球軸承支承。

3、泵的支承：

泵的本體重量(除去轉子部分)由支撐泵體的基礎或梁承受，泵的轉子部分，傳動裝置(包括主傳動部分和動力機)的重量和泵的軸向力均由支撐傳動裝置的樓面基礎承受。

4、傳動軸：

軸流泵的傳動軸，不宜過長，否則會給安裝維修帶來困難。為此對傳動軸的長度作出規定，并依規定供應，用戶訂貨時，要根據安裝圖規定的“L”尺寸選用，進行泵房設計。

5、泵成套供應范圍：

（1）軸流泵本體1臺；

（2）傳動裝置1套；

（3）逆止閥1套；

（4）專用拆卸工具1套。

注：根據用戶需要，可另行配套供應：

（1）電動機；

（2）30°彎管、伸縮管、直管、擴散管；

（3）易損件(包括葉片、橡膠軸承等)。

UK GRIMMImported vertical axial flow pumpsummary:

Imported vertical axial flow pump for the vertical semi adjustable blade axial flow pump, the blade angle can be used according to the conditions required for manual adjustment in the pre assembly of the pump, the pump running in the high zone, play a higher efficiency of pump unit unit. The pumps are 250, 350, 500, 600, 700,, 800, 900, 10, 1000, 1200 and even larger. The flow rate is 700~18000 meters 3/ hours, and the head is between 1.5 meters. The pump is composed of pump body part and the transmission part is composed of two parts, the installation time of water pump foundation and drive (motor) foundation for the two part of the two part of the installation, installation of concentric demanding, professionally installed, its installation height) two basic part of Gao Chengcha) by the design department according to the local water level changes to determine the specific.

The imported vertical axial flow pump is a single stage vertical axial flow pump, which is used to flow along the axis of the pump shaft. This type of pump lift, large flow, suitable for pumping water or similar physical and chemical properties of water and other liquids with suction, the highest temperature is 50 DEG C to the liquid, used for farmland irrigation, industrial circulating water supply, power station City water supply and drainage, water or other water conservancy dock lifting water use a very wide range.

UK GRIMMImported vertical axial flow pumpstructure description:

The pump is mainly composed of pump body and drive parts.

1.Pump body part:

The pump shaft is made of quality carbon steel and is supported by two rubber (or plastic) bearings. In the process of operation, provides a good condition for the lubrication of bearings, bearing a pump shaft, mostly due to the high out of the water, so in the stuffing box (or sealing cap) is provided with a short pipe, the water lubricated bearing instilled with before the start (to be started after the water, irrigation can be stopped). The bearing neck is a high quality carbon steel bushing with a hard chrome surface to improve wear resistance and corrosion resistance. Other main parts, such as horn tube, impeller seat, impeller shell, guide vane, bearing seat, packing seat and shaft coupling, are all made of cast iron, and the water outlet bend is made of steel weldment. The filling is provided with packing to improve the sealing performance of the pump.

The steering of the pump impeller is counterclockwise from the suction port (clockwise from top to bottom). The pump impeller shell (or even in the guide vane body, water inlet horn) surface and the impeller two adjacent, showed a spherical surface, so that the blade installed in any angle, there is a small gap between the impeller and impeller cylindrical shell, to reduce the flow of water loss.

According to the needs of use, the pump can be: "work performance table", "speed up" or "slow down", use or adjust the installation angle of the blade, change the flow and lift, expand the scope of use. The blade is made of high quality ductile iron, and the impeller is corrected by static balance. The blade is fixed on the impeller seat by the blade nut (or the blade tight ring), and the blade and the adjacent surface of the impeller seat are engraved with an angle line. When the water pump leaves the factory, the blade installation angle is generally "zero", the user may adjust the blade installation angle according to the work performance table according to the need. Before installation, the user must re tighten the leaf nut to prevent loosening.

2.Pump transmission part:

According to the power situation in each region and the user's needs, the transmission mode should be determined when ordering, and there are three ways to drive the vertical axial flow pump.

(1)Vertical motor direct drive device:

Motor through bolt is fastened on the motor base, by the end of the driving shaft is connected with a motor shaft coupling Xiao nylon column, the other end is connected with the water pump with rigid coupling, drive shaft is made of high quality carbon steel, the other parts such as motor seat, bearing box, bearing cover are made of cast iron base. When the pump is running, all its axial force (that is, the water pressure on the pump impeller and the total weight of all the pump rotors) is borne by the bearings in the motor seat (or bearing block). The axial displacement of the water pump rotor can be adjusted by the nut in the transmission device, so that the whole water pump unit is simplified, and the installation and maintenance are convenient and reliable.

(2)Vertical motor V-belt drive:

The vertical motor is fixed on the frame by bolts, the frame is fastened on the guide rail, and the frame can slide on the guide rail to adjust the tightness of the belt by the bolt. The radial force during operation is supported by the belt pulley and the radial bearing on the motor.

(3)Vertical half crossing flat belt drive:

The belt pulley is made of cast iron, fixed between the bearing seat and the nut, and installed on the transmission shaft. The radial force of the drive shaft, the weight of the driving part of the pump and the axial force of the operation are all supported by the ball bearing.

3.Pump support:

The body weight of the pump (excluding the rotor part) bearing supported by the foundation of the pump body or beam, the rotor part of the pump, the transmission device (including the main drive part and power machine) the axial force of the weight and the pump are borne by the floor support transmission device.

4.Drive shaft:

Axial pump transmission shaft should not be too long, otherwise it will bring difficulties to the installation and maintenance. To this end, the length of the transmission shaft is specified and supplied according to regulations. When the user orders, the pump house shall be designed according to the "L" size stipulated in the installation drawing.

5.Pump sets of supply range:

(1) Axial flow pump body 1 units;

(2) Driving device 1 sets;

(3) Check valve 1 sets;

(4) 1 sets of special disassembly tools.

Note: the supply can be supplied separately according to the user's needs:
