After using the sprinkler for the first time or putting the water in the tank and the pump clean, it is necessary to fill the tank with the sprinkler that launches the sprinkler after the reference of water, otherwise the time of use is compared. After a long time, it will cause a great degree of damage to the vehicle's sprinkler. Â
The working principle of the water pump of the sprinkler is to rotate by the impeller, and then the liquid is transferred to the liquid under the action of the liquid, but this liquid is the water that we need to fill before we use the water truck. Now. Because the action fluid flows from the inlet of the wheel of the vehicle to the outlet, the pressure and the speed are increased accordingly, and the liquid discharged by the impeller passes through the extrusion chamber. Most of the speed will be converted into pressure energy, and finally it will be sent out along the discharge pipeline. At this time, the impeller inlet and outlet of the sprinkler will form a low pressure or vacuum condition due to the discharge of liquid. And the liquid in the liquid pool of the suction inlet is sucked into the inlet of the impeller of the sprinkler under the effect of atmospheric pressure, and finally the rotating vehicle impeller will continuously suck liquid and discharge it. Â
If the sprinkler is not filled with water, there will be air in the water pump of the sprinkler, and when the impeller rotates, there will be no way to convert the speed in a medium that has passed a certain pressure. Yes, then there is no way to create a low pressure and vacuum at the inlet of the impeller, the liquid will not be inhaled or have the power to discharge. If it is not filled with water, there will be no liquid substance in the pump of the sprinkler to lubricate, and it will cause some damage to the water pump under the influence of large friction when the impeller rotates.
