When using a high-pressure washer for high-pressure water jet cleaning, it is often necessary to adjust the pressure. So, when using a high-pressure washer for cleaning, how should the working pressure be determined to be scientifically appropriate? Let's introduce this aspect below.

There is a misconception when using a high-pressure washer for cleaning work, that is, the higher the pressure, the better. Therefore, users often mistakenly increase the pressure of the high-pressure washer. This is not actually the case. Because as the pressure increases, it means that the components of the high-pressure washer must withstand higher pressure, and higher requirements are placed on the quality and sealing of the components. This will lead to increased costs. Therefore, when using high-pressure water jet cleaning, it is not the case that the higher the pressure, the better. In addition, once the pressure is too high, when the jet is sprayed onto the surface of the cleaning object, it is very likely to cause splashing, which will have an adverse effect on the cleaning work, thus offsetting the effect of the water pressure, and may even cause the water to atomize, resulting in not only reduced cleaning efficiency but also unsatisfactory cleaning results.

From the above analysis, we can see that the pressure required for high-pressure water jet cleaning should be comprehensively considered based on the specific requirements of the work and the nature and degree of fouling on the surface of the cleaning object. Only then can the required pressure be scientifically reasonable. Nowadays, the determination of the required pressure for high-pressure water jet cleaning often uses two methods: the experimental method and the analogy method.
