How to judge whether high pressure spray nozzle needs to be replaced.

　　High-pressure spray nozzle of high-pressure cleaner is an important component of high-pressure cleaners, and it plays a very important role in cleaning work, sandblasting and rust removal. So, how to judge whether the spray nozzle needs to be replaced? Below we will introduce the content of this aspect. I hope to be helpful.

　　(1) When spray shape of high-pressure nozzle of high-pressure cleaner changes, and there are obvious streaks and normal spraying, in order not to affect cleaning effect, it is necessary to replace the nozzle in time.

　　(2) Remove high-pressure nozzle of high-pressure cleaning machine, and then take it to the test bench for actual measurement, and compare the results with new products or catalogs. When high-pressure nozzle is very different from new product, in order not to affect its cleaning effect, it needs to be carried out in time. Then replace.

　　(3) Observing from the appearance, when high-pressure spray nozzle body is deformed by external force, melted, stained with scale, corroded, blocked, worn, etc., the nozzle needs to be replaced in time for the safety of operator.

　　(4) Observing through high-pressure water pump, when pressure drop or pressure rise occurs in high-pressure cleaner, the change of pressure drop means that high-pressure nozzle is severely worn, flow rate increases, and increase in pressure means that high-pressure spray nozzle is clogged.

　　In any case, in order not to affect cleaning work and ensure the serve life of high-pressure cleaner, we need to deal with it in time.
