How to choose the appropriate High pressure cleaning machine nozzle and cleaning pressure according to the cleaning object?
Publish Time: 2024-08-05
When choosing the nozzle and cleaning pressure of the High pressure cleaning machine, it is necessary to comprehensively consider the material, shape, degree of stains and the cleaning effect required for the cleaning object. Here are some specific suggestions:
1. Choose the right nozzle
Nozzle type:
Zero degree nozzle: Mainly used for cleaning small surfaces, deep holes or grooves. The water ejected from the zero degree nozzle is linear, the pressure is relatively concentrated, and it is suitable for cleaning tasks with high precision requirements.
Fan nozzle: Produces a flat and uniform flat jet, the density of the jet is good, and the diffusion angle can also vary in a large range. Mainly used for flushing, spraying, cooling and surface cleaning, suitable for cleaning tasks with larger areas.
Pipe cleaning nozzle: The main technical parameters include outer diameter, number of nozzle holes and nozzle hole injection angle, which is suitable for cleaning the inside of the pipeline. Its selection should be determined according to the inner diameter of the cleaned pipeline, while considering the number of nozzle holes and injection angle to achieve the best cleaning effect.
Nozzle aperture and material:
The nozzle aperture should match the pressure and flow of the High pressure cleaning machine to ensure the cleaning effect.
When selecting nozzle materials, its wear resistance, corrosion resistance and impact resistance should be considered to extend the service life of the nozzle.
2. Choose the right cleaning pressure
Understand the nature of the cleaning object:
Cleaning objects of different materials have different pressure tolerances. For example, fragile materials such as glass require lower pressure, while hard materials such as metal can withstand higher pressure.
The stubbornness of the stains also determines the required pressure. Stubborn stains require higher pressure to remove.
Choose the right pressure range according to the cleaning task:
Low pressure (below 100 Bar): suitable for dirt that is not seriously polluted, such as stripping silt and loose rock formations.
Medium and high pressure (100 Bar-1000 Bar): suitable for dirt that is more seriously polluted, such as stripping mild ship fouling, ordinary derivatives, sand and gravel and mudstone layers.
Ultra-high pressure (greater than 1000 Bar): suitable for dirt that is very seriously polluted, such as stripping granite, marble, limestone, etc.
Gradually increase the pressure:
When starting to clean, it is recommended to start with a lower pressure and gradually increase the pressure. This can avoid damage to the cleaning object and make it easier to clean the dirt.
3. Comprehensive considerations
When selecting the nozzle and cleaning pressure, in addition to considering the nature of the cleaning object, it is also necessary to consider factors such as the performance parameters of the cleaning machine, cleaning efficiency, and cost. It is recommended to conduct tests before actual operation to determine the best nozzle type and cleaning pressure combination.
In summary, choosing the right nozzle and cleaning pressure is the key to ensuring the cleaning effect of the High pressure cleaning machine. By comprehensively considering factors such as the nature of the cleaning object, the performance parameters of the cleaning machine, and the cost, the most suitable nozzle and cleaning pressure combination can be selected.
