**先介绍的是洒水车水泵的拆卸方法：

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

1.找到放油螺丝将其旋下，打开放水阀门将水泵里的剩余液体和齿轮箱里的润滑油排出干净。免得洒水车水泵里的水倒出弄脏衣服。

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.把管道和机座螺栓一一拆除，将泵取下，拆去进口法兰。拆下法兰盘的时候要记住水泵进出口的安装位置，方便安装时对接进出口。

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.拆叶轮。先旋下叶轮螺母，再拆下洒水车水泵与齿轮箱的联接螺母，然后用M12螺栓慢慢的顶开螺孔中旋入的M12螺栓，，这时候泵体和齿轮箱同时被顶开，**级叶轮自动脱出，，**级叶轮，机械密封就和齿轮箱一起与泵体分离。

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.拆去齿轮箱盖和输入轴承盖，将输入轴承由水泵体侧打出，**从箱体上方将主动齿轮取出。

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.

洒水泵安装方法和拆卸的步骤是相对的，只是要注意一下几点：

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

1.安装前应先把洒水泵两侧的撑脚卸下，将泵轴心与联轴器对准，把齿轮箱上的四个螺栓拧紧后再将撑脚装上。

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.注意对整齐油封间隙，调试叶轮的位置，不要使其在旋转时擦到箱体。

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.洒水泵进出口管路必须紧固在车身上，不能使其重量被泵承受，管路中还应加装过滤网。
