Sprayer Common Faults and exclusion method

Many types of spray nozzles , here rocker and worm sprinkler common faults and troubleshooting .

1 Water tongue abnormal traits Rotating sprinklers if working properly, in the absence of otherness ( rocker style guide or worm water heaters · impeller ) blocked, the water in the vicinity of the nozzle tongue should have a smooth , transparent, round dense paragraph after paragraph in dense water tongue gradually turned white and was crushed ; its range of not less than 85% of the standard value , and should be good atomization . Otherwise, water tongue trait abnormalities. Its causes and remedies as follows: ① water tongue just left the nozzle on the rough surface of an opaque , but the water is still the mainstream of the tongue is circular, because sprinklers processing rough, burrs or damage. Sprinklers should be polished or replace the nozzle . ② water leaves the nozzle on the tongue just a spread , no round dense paragraphs. The main reason is inside the nozzle was badly damaged and should be replaced ; rectifier distortion , should be repaired or replaced ; flow channel within the blockage should remove foreign bodies .

2 range is not enough water tongue

① range is not enough , but the water is still good atomization tongue , mainly due to the nozzle speed is too fast , you should adjust small nozzle speed . ② range is not enough and the water jet atomization poor. The reason is not enough pressure , may be required to increase the pressure .

3 sprinkler rotation is not normal

① rocker works fine, but the head does not turn or rotate very slowly. The following reasons: a hollow shaft and the sleeve shaft gap is too small , should increase its gap ; between being blocked into the sediment should be removed cleaned ; installation sleeve shaft screw too tight, should be relaxed . ② arm angle is too small. Reasons: rocker spring too tight, should be appropriately loosen ; rocker mounted too high , water flowing water can not completely cut tongue , should be lowered ; rocker arms and rocker arm shaft with tight , should increase the gap ; pressure low and should be increased . ③ rocker angle is large enough, but the percussion weakness. The reason is water deflector tongue cut too deep , so that the power has not been fully tap rocker hand pump sprayers sprayed body incurs in red open . Tapping block should thicken . ④ rocker percussion frequency instability , unsteadiness . The reason is the rocker arm and shaft rocker shaft with Songkuang or loose , you need to identify the reasons corrected. ⑤ not return after arm throw . Mainly due to the rocker arm spring is too loose , you should tighten the springs.

4 worm type ( impeller ) nozzle rotation is not normal

① impeller idling but the head does not turn . Main reasons: the impeller shaft and the small worm screw loose coupling between or pins off, should be tightened ; big worm shaft and sleeve positioned between the screw loose , should be tightened ; reversing gear did not catch , should be pulling the lever to make commutation gear to catch . ② water tongue is normal but the impeller does not turn, fruit tree sprayers the body does not turn . Main reasons: worm or gear oil, resistance is too large , you should add oil ; positioning screws too tightly , resulting in a large worm with eccentric , should be appropriately loosen ; impeller is stuck foreign body , should be cleared ; worm , gear or hollow shaft and shaft sleeve rust prison, should rust refueling.

5 leaking nozzle rotating parts

① gasket into the sediment, so that the sealing surface is not sealed , remove the hollow shaft clean. ② insufficient precision nozzle , the hollow shaft and the sleeve shaft is not closely with the end surface , should be repaired or replaced.
