Industrial enterprises have strict requirements for power supply continuity. Diesel generator sets are preferred as backup power sources due to their rapid startup and high reliability. However, improper selection may lead to power outages, equipment damage, and even increase operational costs. The following discusses several key purchasing points from three dimensions: power calculation, technical configuration, and scenario adaptation.
1. Accurate Power Calculation: Avoid “Overloading”
Consider both base load and peak load: In addition to the total power of conventional equipment, the starting current of high-power motors needs to be separately calculated, reaching 6-8 times the rated value.
Reserve Coefficient: Select based on 1.2 times the calculated load to avoid long-term full-load operation. It is recommended to keep the load rate within 70%-80%.
2. Core Configuration: Power and Control System are Key
Power System: Prioritize 12-cylinder V-type diesel engines with dual turbocharging design to compensate for 15% power loss in high-altitude areas. The heavy-duty crankshaft has a maintenance cycle of up to 50,000 hours.
Intelligent Control: The PLC touch screen must support load prediction algorithms. When multiple machines are connected in parallel, the circulating current should be controlled within 3%. This ensures the stability of the parallel operation.
3. Scenario Adaptation: Dual Compliance of Environment and Regulations
Strict Environmental Protection: In dusty workshops, high-grade air filters should be equipped. In high-temperature environments, a water-cooling system should be selected to reduce vibration. The vibration value of the shock absorption foundation should be ≤ 0.5mm/s.
Environmental Protection Compliance: Install noise and sound insulation covers. In the context of carbon neutrality, prioritize models with exhaust treatment systems. Nitrogen oxide emissions should be reduced by more than 40%.
4. Redundancy Design: N+1 Configuration Ensures Safety
Single Machine or Parallel Operation: For important loads, it is recommended to adopt N+1 redundancy. When a single machine fails, other units will automatically take over. The parallel operation capacity should be ≥ 4 units, and seamless switching is supported.
Fuel Reserve: Reserve diesel for 8 hours of full-load operation. Install an online oil purification device to avoid impurities blocking the fuel injector.
5. Full Life Cycle Cost: Don’t Just Focus on Purchase Price
Fuel Consumption Optimization: Choose load-adaptive adjustment models. The waste heat recovery system can effectively improve efficiency and save fuel costs.
Maintenance Cost: Conduct 12 basic parameter checks daily, test 30% of the load for 1 hour per week. Preventive maintenance can reduce 60% of downtime due to faults.
