What are the differences between the high-pressure cleaning machines 280 and 380?

The main difference between the high-pressure cleaning machine 280 and 380 is reflected in the voltage specification, application scenario and equipment performance suitability. The following is analyzed from multiple dimensions:

Voltage Specifications and Power Adaptability

280 model: usually refers to the frontal voltage AC280V high voltage washing machine, more common in single-phase power supply scenarios. This kind of equipment power range is generally 5-10KW, suitable for families, small shops or mobile operation scenarios, low power grid requirements, but the high-voltage output capacity is relatively limited.

380 models: the use of three-phase AC380V power supply, belonging to industrial grade equipment, the power is generally above 15KW (such as the example parameters up to 15KW / h). Three-phase power provides a more stable current output, reduces the impact of voltage fluctuations on the equipment, and is suitable for long-term continuous operation.

Differences in performance parameters

Pressure and flow: 380 models usually have higher pressure (such as 350 bar) and flow (such as 21 L / min) due to the power advantage, which significantly improves the cleaning efficiency. For example, when cleaning the surface of large equipment, the 380 machine can reduce the operation time by more than 50%. 280 model pressure in 150-200 bar, flow 8-15 L / min, more suitable for light cleaning tasks.

Stableness and durability: The 380 model uses a three-phase motor with a small torque fluctuation and smoother operation, and the equipment life is generally 30%-50% longer than the 280 model.Its heavy-duty frame design (e.g. 198 KG weight in the example) and low noise (≤ 65 dB) are also more suitable for industrial environments.

Application scenarios divided

280 model suitable scenarios:

Home garage cleaning, small catering kitchen oil cleaning

Mobile cleaning service (required with generator)

Sites with limited budgets and limited electricity usage environments

Suitable scenarios for the 380 model:

Plant equipment maintenance, ship rust removal, building facades cleaning

Municipal sanitation, large parking lots are cleaned regularly

Industrial scenarios that require more than 12 hours of continuous operation

Cost and maintenance considerations

Initial input: The price of the 380 model is usually 1.5-2 times that of the 280 model (market price range: about 0.8-2 million yuan for the 280 model, about 2-5 million yuanfor the 380 model), but the unit cleaning cost can be reduced by 40%.

Maintenance complexity: The 380 model requires professional electricians to install the three-phase circuit, and maintenance needs to regularly check the electric motor insulation performance. The 280 model has a lower maintenance threshold but a relatively high failure rate.

Industry Standards and Adaptability

According to the "high pressure washing machine safety specification" (GB / T 31592-2015), industrial high pressure washing machine must use three-phase power supply to ensure safety. The 380 model meets such mandatory standards, while the 280 model is mostly used in non-mandatory certification scenarios.
