II. Detailed Explanation of WBZ400 Power Requirements
The total power requirement of the WBZ400 is a key factor in equipment selection and supporting power supply design. The primary source of power consumption for the entire workstation is the motor drive devices in each system.
Key Power Consumption:
- Mixing Main Unit Motor: 55kW (Dual Motor Drive)
- Inclined Belt Conveyor Motor: 22kW
- Flat Belt Conveyor Motor: 18.5kW
- Powder Screw Conveyor Motor: 2 x 7.5kW
- Air Compressor: 4kW
- Dust Removal Fan: 1.5kW
- Water Pump and Auxiliary Equipment: 3kW
The total installed power of the WBZ400 stabilized soil mixing plant is typically 119kW, depending on the selected configuration and the equipment manufacturer's design.
III. Transformer Capacity Selection Guide
Selecting the appropriate transformer capacity is crucial to ensuring stable operation of the WBZ400. Under-sizing the transformer can lead to equipment failure or malfunction, while over-sizing wastes resources and increases operating costs.
The selection calculation formula is as follows:
Transformer capacity (kVA) ≥ (Total installed power × Demand factor Kx) / Power factor cosφ
Parameter value explanation:
- Total installed power: 119 kW
- Demand factor Kx: 0.65 - 0.75 (recommended value 0.7)
- Power factor cosφ: 0.80 - 0.85 (recommended value 0.83)
Based on the above formula and parameters, the calculation result is:
Transformer capacity ≥ (119 × 0.7) / 0.83 ≈ 100.36 kVA
Based on transformer rated capacity standards, a 150 kVA transformer is recommended.
Selection Recommendations:
1. Reserve margin: It is recommended to add a 20%-30% capacity margin to the calculation.
2. Consider starting current: Large motors have high starting currents, requiring sufficient transformer capacity.
3. Environmental Factors: High temperatures can affect the transformer's output power, so the capacity needs to be increased appropriately.
4. Future Development: Consider the potential addition of electrical equipment.
