What sprayer common main malfunction How to solve

 Many types of sprayers nozzles, the following will introduce some common malfunction and troubleshooting.
1. Water tongue abnormal traits, rotary sprinklers if working properly, in the absence of otherness becomes blocked, the water should be available near the nozzle tongue a smooth, transparent circular dense paragraph after paragraph in dense white water was gradually crushed tongue ; 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 because 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 abnormal working properly, 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 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 nozzle rotation is not normal ① impeller rotation is not normal 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, spray 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 part ① washer nozzle rotating part enters 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.
