Common Faults And Solutions Of Spray Nozzle

1. Abnormal tongue morphology
Symptom: If the rotary nozzle works normally, there should be a smooth, transparent circular dense section of the water tongue near the nozzle when there is no other obstruction. After the dense section, the water tongue gradually turns white and is crushed. If the water tongue is rough, opaque, or scattered as soon as it leaves the nozzle, it indicates abnormal water tongue characteristics.
Reason and solution:
The water tongue is rough and opaque as soon as it leaves the nozzle surface, but the mainstream is still circular: the reason is that the nozzle processing is rough, with burrs or damage. The nozzle should be polished or replaced.
As soon as the water tongue leaves the nozzle, it disperses without a circular dense section: the main reason is that the nozzle is severely damaged internally, the rectifier is twisted and deformed, or there are foreign objects blocking the flow channel. The nozzle should be inspected and replaced, the rectifier should be repaired or replaced, and foreign objects should be removed.
2. Insufficient range of water tongue
Symptom: Insufficient range may be caused by excessive rotational speed or insufficient working pressure.
Reason and solution:
The range is not enough, but the nozzle atomization is good: the reason is that the rotating speed of the spray nozzle is too fast, so the rotating speed of the nozzle should be reduced.
Insufficient range and poor water tongue atomization: The reason is that the working pressure is not enough, and the pressure can be adjusted as required.
3. nozzle blockage
Symptom: nozzle blockage is one of the common faults, usually caused by impurities, accumulated water or dust inside the nozzle, which prevents the nozzle from spraying liquid.
Reason and solution:
Clean the nozzle with a cleaning agent and check if there are any debris blockages inside the nozzle. Replace the nozzle if necessary.
Regularly clean the nozzle and use a soft bristled brush or fine needle to remove blockages; Install a filter to remove impurities from the cleaning solution; Use the recommended cleaning solution and avoid using incompatible or heavily contaminated cleaning solutions.
4. Pipeline blockage
Symptom: Pipeline blockage is usually caused by the accumulation of liquid, debris, or bubbles inside the pipeline, which prevent the flow of liquid.
Reason and solution:
Clean the pipeline with cleaning agent and check if there are any debris or device blockages inside the pipeline. Replace the pipeline if necessary.
5. Water leakage fault
Symptoms: Water leakage faults may be caused by various reasons, such as electric leakage or liquid leakage.
Reason and solution:
Check if the power supply is properly connected, if there is poor contact, if the wires are damaged, and replace the power cord if necessary.
Liquid leakage is caused by damage, aging, or inadequate assembly of parts such as nozzles, pipelines, or containers. Check the relevant components and replace or reassemble them if necessary.
6. Noise malfunction
Symptoms: Noise is usually caused by bearing wear, fan blade wear, and other issues generated by mechanical components such as motors and motors.
Reason and solution:
Regular maintenance and inspection of mechanical components to ensure good lubrication, and timely replacement of worn parts.
7. Nozzle wear and tear
Symptoms: Long term use or frequent operation may cause nozzle wear, manifested as an increase in nozzle outlet size and a decrease in spraying effect.
Reason and solution:
Regularly inspect the nozzle and replace it promptly if wear is found; Choose nozzle materials with good wear resistance, such as ceramics or silicon carbide; Adjust the cleaning pressure and flow rate to avoid excessive pressure and flow accelerating nozzle wear.
8. Nozzle leakage
Symptom: Nozzle leakage may be caused by aging, damage, or improper installation of seals.
Reason and solution:
Regularly inspect the seals and replace them promptly if aging or damage is found; Ensure proper installation of the nozzle to avoid excessive tightening or unstable installation.
9. Spray angle deviation
Symptom: The deviation of the spray angle may be caused by improper installation, external impact, or prolonged use.
Reason and solution:
Regularly check the installation angle of the nozzle to ensure it is consistent with actual needs; Avoid external impact on the nozzle and ensure that it operates in a safe environment.
10. Loose or detached nozzle
Symptoms: Loose or detached nozzles may be caused by loose installation, damaged threads, or prolonged vibration.
Reason and solution:
Use locking agents or anti loosening washers to enhance the tightening effect of threads; Regularly check the installation status of the nozzle to ensure its stability and reliability.
