齒輪油泵的安裝方法和注意事項

　　齒輪油泵主要依靠泵缸與嚙合齒輪間所形成的工作容積變化和移動來輸送液體或使之增壓的回轉泵。其安裝質量的好壞，直接影響到泵的使用。

　　一、齒輪油泵的安裝方法：

　　1、將機組放在埋有地腳螺栓的基礎上，在底座與基礎之間，用成對的楔墊用校正用。

　　2、松開聯軸大，用水平儀分別放在泵軸和底座上，通過調整楔墊，校正機組水平，適當擰緊地腳螺栓，以防走動。

　　3、校正泵軸和電機軸的同心度，在聯軸大路外圓上，允許偏差0.1毫米；兩聯軸器平面的間隙應保護2～4毫米，(小泵取小值)間隙要均勻，允差0.3毫米。

　　4、在接好管路及確定電動機轉動方向后，再接上聯軸器，并再校核一遍軸的同心芳。

　　5、在機組實際試運行2～3小時后，作后檢查，如無不良現象，則認為安裝合格。

　　6、在安裝過程中，為防止雜物落入機器內，機組的孔眼均應蓋好。

　　7、為防止管線中雜物進入泵內，對新安裝的管線，在泵膠應裝設過濾器，其效果優良截面應大于吸入管截面的2～3倍。

　　Installation method and precautions of gear oil pump

　　Gear oil pump is a rotary pump that mainly relies on the change and movement of working volume formed between pump cylinder and meshing gear to transport liquid or pressurize it. Its installation quality directly affects the use of the pump.

　　1、 Installation method of gear oil pump:

　　1. Place the unit on the foundation with embedded anchor bolts, and use pairs of wedge pads between the base and the foundation for correction.

　　2. Loosen the coupling, place the level on the pump shaft and base respectively, adjust the wedge pad to correct the unit level, and properly tighten the anchor bolts to prevent walking.

　　3. Correct the concentricity of pump shaft and motor shaft, and the allowable deviation is 0.1mm on the outer circle of coupling road; The clearance between the two coupling planes shall be protected by 2 ~ 4mm (the smaller value is taken for the small pump). The clearance shall be uniform with a tolerance of 0.3mm.

　　4. After connecting the pipeline and determining the rotation direction of the motor, connect the coupling and check the concentricity of the shaft again.

　　5. After 2 ~ 3 hours of actual trial operation of the unit, conduct post inspection. If there is no defect, it is considered that the installation is qualified.

　　6. During installation, in order to prevent sundries from falling into the machine, the holes of the unit shall be covered.

　　7. In order to prevent sundries in the pipeline from entering the pump, a filter shall be installed in the pump rubber for the newly installed pipeline, with excellent effect, and the section shall be 2 ~ 3 times larger than that of the suction pipe.

　　二、安裝齒輪油泵的過程中應注意的事項：

　　1、齒輪油泵安裝的好壞，對泵的平穩運行和使用有很重要的影響，所以安裝校正工作仔細地進行，不得草率行事。

　　2、齒輪泵吸入管的安裝高度、長度和管徑應滿足計算值，力求簡短，減少不需要的損失(如彎頭等)；并保護泵在工作時，不過其允許汽蝕余量。

　　3、齒輪泵的吸入和排出管路應該有支架。泵不允許承受管路的負荷。

　　4、安裝管道泵的地點應足夠寬敞，以方便檢修工作。
