High-pressure cleaning machine flow rate and pressure: how to choose a cleaning machine suitable for oneself

I. Understanding the Concepts and Differences of Flow Rate and Pressure in High-Pressure Cleaning Machines

The flow rate of a high-pressure cleaning machine refers to the amount of water pumped by the machine per unit time, usually measured in liters per hour. A higher output flow rate generally results in greater washing efficiency.

Pressure refers to the degree of water pressure applied by the high-pressure cleaning machine during the cleaning process, typically measured in bars. The output pressure determines the cleaning intensity. For stubborn stains, bird droppings, or car tires, insufficient pressure may require the use of a Lotus nozzle for boosting the pressure. Additionally, for more effective cleaning, especially of body electrostatic dust, higher pressure can lead to better results. However, relying solely on high pressure to remove body electrostatic dust can cause significant damage to the paint surface over time due to prolonged exposure to such intense pressure.

The flow rate and pressure of high-pressure cleaning machines are usually interrelated; that is, as the flow rate increases, the pressure decreases, and as the pressure increases, the flow rate decreases.

So, here’s the question: when choosing a high-pressure cleaning machine, is pressure more important or flow rate more important?

Personally, I believe that flow rate is more crucial than pressure. For household car washing and floor cleaning, it's ideal to keep the pressure between 70 bar and 100 bar, with a flow rate of 10 L. For car wash shops, the pressure should be set between 120 bar and 140 bar, with a flow rate between 12 L and 15 L.

In addition, the choice can also be based on the specific needs of the galaxy, the material of the objects to be cleaned, and the frequency of use for the cleaning machines.

1. Choose a cleaning machine based on the specific cleaning requirements.

For scenarios requiring cleaning large areas and substantial amounts of dirt and grime, high-pressure cleaners with higher flow rates and lower pressures are necessary. Conversely, for cleaning small areas with minimal dirt, cleaners with lower flow rates and higher pressures are required.

2. Choose a cleaning machine based on the material of the object being cleaned.

For hard materials, high-flow and high-pressure cleaning machines are necessary to thoroughly remove dirt and debris. For soft materials, which are prone to damage, low-flow and low-pressure cleaning machines should be chosen to minimize damage to the soft material.

3. Choose based on the frequency of use for the cleaning machine.

If frequent cleaning is required, it is recommended to choose a higher-quality cleaning machine to ensure the longevity of the equipment. Otherwise, a more affordable option can also be considered.

In summary, selecting the right high-pressure cleaning machine involves considering several factors and choosing the appropriate flow rate and pressure based on specific cleaning needs and scenarios. I hope this article assists readers in making an informed decision when selecting a high-pressure cleaning machine.
