**先介紹的是灑水車水泵的拆卸方法：

First of all, this paper introduces the method of removing the water pump:

1.找到放油螺絲將其旋下，打開放水閥門將水泵里的剩余液體和齒輪箱里的潤滑油排出干凈。免得灑水車水泵里的水倒出弄臟衣服。

1 find the oil drain screw to screw down, open the drain valve will be the residual liquid in the pump and the gear box of the lubricating oil discharged clean. Lest the sprinkler pump the water out of dirty clothes.

2.把管道和機座螺栓一一拆除，將泵取下，拆去進口法蘭。拆下法蘭盤的時候要記住水泵進出口的安裝位置，方便安裝時對接進出口。

2 of the pipeline and the base bolt 11 removed, the pump is removed, remove the inlet flange. Remove flange plate when you want to remember the installation location of the pump inlet and outlet, to facilitate the installation of the docking port.

3.拆葉輪。先旋下葉輪螺母，再拆下灑水車水泵與齒輪箱的聯接螺母，然后用M12螺栓慢慢的頂開螺孔中旋入的M12螺栓，，這時候泵體和齒輪箱同時被頂開，**級葉輪自動脫出，，**級葉輪，機械密封就和齒輪箱一起與泵體分離。

3 open impeller. First unscrew the impeller nut, then remove nut under sprinkler pump and the gear box, and then slowly open the top M12 bolt M12 bolt, screw in the screw pump and the gear box, this also is to open the top, the first stage impeller, second stage impeller automatic extrusion, mechanical seal and gear box. With the pump body separation.

4.拆去齒輪箱蓋和輸入軸承蓋，將輸入軸承由水泵體側打出，**從箱體上方將主動齒輪取出。

4 remove the gear box cover and enter the bearing cover, the input bearing by the pump body side, and finally from the top of the box will take the initiative to remove the gear.

灑水泵安裝方法和拆卸的步驟是相對的，只是要注意一下幾點：

Sprinkler installation and removal of the steps are relative, but to pay attention to the following points:

1.安裝前應先把灑水泵兩側的撐腳卸下，將泵軸心與聯軸器對準，把齒輪箱上的四個螺栓擰緊后再將撐腳裝上。

1 before the installation of the pump should be on both sides of the foot of the foot of the pump, the pump shaft and shaft coupling alignment, the gear box on the four bolts after tightening will be installed on the support.

2.注意對整齊油封間隙，調試葉輪的位置，不要使其在旋轉時擦到箱體。

2 pay attention to the neat oil seal clearance, the position of the impeller, do not make it in the rotation to wipe the box.

3.灑水泵進出口管路必須緊固在車身上，不能使其重量被泵承受，管路中還應加裝過濾網。
