### I. Clarify the Application Scenario Requirements

**Cleaning Object Types**

- **Industrial Scenarios** (such as auto parts, metal machined parts): Models with a pressure ≥ 50MPa and support for ultrasonic composite cleaning should be selected to deal with stubborn contaminants like oil stains and metal shavings.

- **Food/Pharmaceutical Industry**: Models made of all - stainless - steel material with a no - dead - angle spraying design are preferred, ensuring that the residue concentration ≤ 0.1mg/L (meeting food - grade standards).

**Compatibility with Production Lines**

When it needs to be linked with AGV carts and industrial robots, select models that support standard communication protocols (such as Modbus TCP) to achieve fully automatic loading and unloading.

### II. Comparison of Core Parameters

| Parameter | Household/ Light Industry (Reference Value) | Heavy Industry (Reference Value) |

|--|--|--|

| **Pressure Range** | 20 - 50MPa | 50 - 200MPa (Ultra - high - pressure models) |

| **Flow Rate** | 8 - 15L/min | 15 - 50L/min |

| **Power** | 2 - 5kW | 5 - 30kW (Variable - frequency drive optimizes energy consumption) |

| **Cleaning Agent Compatibility** | Water - based/Neutral solvents | Special formulas for strong acids/strong alkalis |

### III. Screening of Intelligent Functions

**Control and Monitoring Systems**

- **Adaptive Adjustment**: Equipped with a PLC or microcomputer system to automatically match water pressure, temperature, and cleaning time (for example, Mijia models support 5 preset modes).

- **Remote Operation and Maintenance**: Real - time monitoring of equipment status through a mobile APP/cloud platform, with a fault warning response time ≤ 30 minutes.

**Cleanliness Verification Ability**

Integrate a visual inspection module to automatically identify surface residues on workpieces (with an accuracy of up to 0.01mg/cm²) and generate a cleanliness report.

### IV. Energy Efficiency and Environmental Protection Indicators

**Water Recycling Technology**

- A three - stage filtration system (magnetic separation + vortex precipitation + precision filter element) can reduce water consumption by 62%, and the filter element life is extended to 6 - 12 months.

- An optional wastewater purification module can make the discharged water quality meet the GB 8978 - 2025 standard.

**Energy - Saving Design**

- Variable - frequency drive technology reduces energy consumption by 40% (for example, the no - load power of Bohr models ≤ 0.5kW).

- The intelligent temperature control system reduces heat loss, and the temperature fluctuation of constant - temperature cleaning water is ≤ ±2℃.
