High-pressure cleaning nozzle is mostly used in high-pressure cleaning industry, to ensure that the cleaning is clean and thorough, first of all, to ensure that the nozzle is intact and can work normally. So, when to replace the high-pressure cleaning nozzle? Below, SAN An technology to give you a few suggestions.

1. Test the flow

 
Remove the high-pressure cleaning nozzle for testing, record the flow rate, compare the test results with the new product, and replace the high-pressure cleaning nozzle when the difference is obvious.
 

2. Observe the shape of the spray

 
Under high pressure conditions, the spray shape will be affected by the wear of the nozzle. For example, the wear of the nozzle, the blade in the cavity, and the diameter of the cavity. When the spray shape streaks from the high-pressure cleaning nozzle are obvious or can not be sprayed normally, in order not to affect the cleaning effect, it is necessary to replace the nozzle in time.


 

3, observe the corrosion

 
Some of the liquid inside the nozzle is corrosive, and the corrosion of the nozzle will affect the normal operation of the nozzle. Observe the appearance of the nozzle, if the nozzle deformation, adhesion scale, corrosion, obstruction and other phenomena, should be replaced in time.
