Introduction: Why the update is necessary
Today's manufacturing systems require constant updates to ensure efficiency, compliance and cost reduction. Old conveyor systems often do not meet modern energy efficiency standards, and also lose compliance with the requirements of EU Ecodesign and State energy audits. Upgrading conveyor systems not only increases efficiency, but also reduces the risk of downtime, improves safety and maintains regulatory compliance.
Evaluation of the old system before the upgrade
A detailed evaluation of the current system must be performed before starting the upgrade. The main assessment criteria include:
| Criterion | Assessment | Standard |
|---|---|---|
| Efficiency of energy consumption | 50% | EN 13469 |
| Limit of Failure (MTBF) | 1500 hours | DSTU 4319:2016 |
| Availability of sensors | Ні | ISO 9001 |
| Energy efficiency | 55 kWh/h | EU Ecodesign |
Modern alternatives
Upgrading conveyor systems is possible with modular drives, smart sensors and energy recovery systems. Below is a comparison of old and new technology:
| Criterion | Old version | A new option |
|---|---|---|
| Efficiency | 50% | 85% |
| Energy consumption | 55 kWh/h | 15 kWh/hour |
| MTBF | 1500 hours | 6000 hours |
| Cost (€) | 10000 | 25000 |
| Energy recovery | Ні | Yes |
Calculating Return on Value (ROI)
Upgrading the conveyor system will provide significant economic benefits. Below is a detailed calculation:
- Energy consumption: 55 kWh/h * 24 h/day * 300 days = 396,000 kWh/year
- Energy consumption: 396,000 kWh * €0.12 = €47,520/year
- Cost of production shutdown: 50 h/year * €200 = €10,000/year
- Annual security costs: €5,000
- Annual maintenance costs: €10,000
- Total costs: €72,520/year
- The cost of the upgrade: €25,000
- Payback period: 1.5 years
The upgrade will provide savings of €50,000/year, which corresponds to a payback period of 1.5 years.
Implementation plan
The upgrade of the conveyor system should be done in phases to minimize production stoppages:
- Phase 1: Planning (2 weeks)
- Phase 2: Supply of components (1 week)
- Phase 3: Installation (2 weeks)
- Phase 4: Commission (1 week)
Upgrades are performed using modular drives that ensure minimal production downtime.
Technical challenges
The following issues may occur during the update:
- Incompatibility of components
- Incorrect installation
- Lack of sensors
Solution:
- Use components conforming to DSTU and EN standards
- Carry out control checks during installation
- Install smart sensors to track system status
Case study: before and after
The conveyor system was modernized at the enterprise in Ukraine. Before updating:
- Efficiency: 50%
- Energy consumption: 55 kWh/h
- MTBF: 1500 hours
After update:
- Efficiency: 85%
- Energy consumption: 15 kWh/hour
- MTBF: 6000 hours
The upgrade reduced power consumption by 72.7% and MTBF increased by 4 times.
Commission and acceptance
After installation, the system is tested according to the following criteria:
- Efficiency of energy consumption
- Limit of Failure (MTBF)
- Functionality of the system
All indicators must comply with DSTU, EN and ISO standards.
Conclusion
Conveyor system upgrades are critical to ensure efficiency, compliance and cost reduction. The use of modular drives, smart sensors and energy recovery systems will provide significant economic benefits.
