Oct 25, 2017

Impeller is one of the most critical parts in the sprayer, which directly affects the quality of spray. The impeller is composed of front impeller and rear impeller, and the front and rear impellers are connected by eight fixed pins. In the rear impeller, each pin hole on both sides of the 1.5 mm thick shoulder, to ensure that the front and rear impeller assembly, there is a certain distance between the two. The front and rear impellers are installed to press one end of the micro motor shaft so as to rotate the impeller.

The front and rear impellers are all disk shaped, mainly to prevent liquid drops from sticking to the impeller surface or to be thrown out directly, resulting in phytotoxicity. In order to make the atomization point more uniform, the outer edge of the two impeller is engraved with 36. A cone angle of small teeth, to decrease the adhesion of the film on the surface attached to the impeller, and be thrown off when the fog point was the launch point, so that liquid along it regularly thrown out of a thin liquid.

The anti end of the liquid sleeve is 7 mm diameter hole sleeve before the impeller shaft; the other end is extended out of the motor shell end groove, prevent rusting shaft exposed contact the liquid liquid. The motor set with the impeller with high-speed rotation can be thrown out of the liquid medicine splashing attached to it, to prevent the infiltration of liquid the interior of the motor, causing corrosion. The grease can also be coated in the anti - liquid sleeve, so as to increase the lubrication of the bearing and prolong the service life of the motor.

Head holder Wu Guowei column, set the handle pipe. A medicine bottle support is installed in the upper fork. There are two round holes with a diameter of 4 mm on the lower side of the fork, which are matched with five semicircle grooves on the shoulder of the medicine bottle support, so that the nozzle body has five different rotating angles, and can be adjusted according to the operation requirements. A round hole with a diameter of 3.2 mm is used in the fork for the purpose of threading the wire.
