Sprayer nozzle type more, the following describes the rocker and worm gear sprayer common fault and troubleshooting methods.
1. Water tongue traverse Exceptional rotary nozzle If the work is normal, there should be a smooth, transparent rounded, close to the nozzle near the nozzle when there is no obstruction (rocker type water guide or impeller of worm gear) Segment, after the dense section of the water tongue gradually become white and smashed; its range should not be less than 85% of the standard value, and should be well-fried. Otherwise the water tongue traits abnormal. The reason and the exclusion method is: ① water tongue just left the nozzle, the surface rough and opaque, but the water tongue is still the mainstream of the round, because the nozzle processing rough, burr or damage. The nozzle should be polished or replaced. ② water tongue just left the nozzle to spread, there is no circular dense section. The main reason is that the damage inside the nozzle is serious, should be replaced; rectifier distortion, should be repaired or replaced; flow of foreign body blockage, should be removed foreign body.
2. Water tongue range is not enough ① range is not enough, but the water tongue is still good atomization, the main reason is the nozzle speed is too fast, should adjust the nozzle speed. ② range is not enough and water tongue spray difference. The reason is that the work pressure is not enough to increase the pressure on demand.
3. Rocker-type nozzle is not normal rotation ① rocker work is normal, but the nozzle does not turn or turn very slow. The reasons are as follows: hollow shaft and sleeve shaft clearance is too small, should increase its gap; between the two into the mud blocking, should be removed clean; installation sleeve twist too tight, should be appropriate to relax. ② rocker angle is too small. The rocker spring is too tight, should be properly loose; rocker arm is installed too high, the water guide can not be completely cut into the water tongue, should be lowered; rocker and rocker shaft with too tight, should increase the gap; Inadequate, should be raised. ③ rocker angle is large enough, but percussion weak. The reason is that the deflector cut into the water tongue is too deep, so that the arm of the arm has not yet fully knock on the spray that is washed open. The percussion block should be thickened. ④ rocker percussion frequency instability, suddenly fast or slow. The reason is the rocker and shaft with loose or rocker shaft loose, need to identify the reasons to correct. ⑤ rocker throw off can not return. The main reason is the rocker spring is too loose, should adjust the spring.
4. worm gear (impeller type) nozzle rotation is not normal ① impeller idling but the nozzle does not turn. The main reason: the coupling between the impeller shaft and the small worm wheel loose or pin off, should be tightened; large worm wheel and sleeve between the positioning screw loose, should be tightened; for the tooth did not catch, Gear catch. ② the water tongue is normal but the impeller does not turn, the spray body does not turn. The main reason: worm or gear lack of oil, resistance is too large, should add lubricating oil; positioning screw twisted too tight, resulting in large worm wheel eccentricity should be properly released; impeller was foreign body stuck, should be removed; Hollow shaft and sleeve shaft rust, should be rust refueling.
5. Sprinkler part of the water leakage ① gasket into the sediment, so that the sealing surface is not sealed, should be removed hollow shaft clean. ② nozzle processing accuracy is not enough, hollow shaft and sleeve shaft can not be closely matched with the face, should be repaired or replaced.
