Frequently Asked Questions
What is the driving mode utilized in these air compressors?
All specified air compressor models (from 10A to 350A) employ a Direct Drive transmission mode, which ensures high efficiency, reduced power loss, and lower maintenance requirements compared to belt-driven alternatives.
What startup method do these compressor systems use?
These units utilize a Star-Delta (Y-Δ) start-up configuration. This startup mode effectively minimizes the initial inrush current during startup, protecting the motor and ensuring smoother grid integration.
What are the power supply specifications for these compressors?
The standard power supply configured for these models is 380V/50Hz/3P (3 Phase). However, customized voltage and frequency options are available to meet various regional standard requirements.
How does discharge pressure affect free air delivery?
As the discharge pressure increases (from 0.7 MPa to 1.25 MPa), the free air delivery (m³/min) slightly decreases. Selecting the right combination of flow and pressure is critical for optimal tool and machinery operation.
How does the lubricating oil requirement scale across models?
The required lubricating oil volume scales with unit size. Smaller units like the 10A require 4 liters, medium units range between 14 to 30 liters, and the heavy-duty industrial models (up to 350A) require up to 125 liters for optimal heat dissipation and lubrication.
What are the outlet connection sizes for different models?
The discharge outlet diameter increases with the air delivery capacity: smaller models use thread connections starting from G¼ up to G2½, while the high-capacity models (300A and 350A) use DN100 flange connections to handle large volumes of compressed air flow efficiently.
