Introduction
Modern requirements for efficiency, energy efficiency and compliance with regulations force industrial enterprises to look for ways of modernization. Replacing pneumatic control systems with electric motors is a critical step in achieving these goals. This not only improves control accuracy, but also ensures energy efficiency and compliance with DSTU, EN and ISO standards.
Evaluation of old systems
Before starting the upgrade, a detailed assessment of the existing system must be carried out. Below is a table of criteria for evaluation:
| Criterion | Assessment | Activity |
|---|---|---|
| Energy efficiency | low | Pneumatic systems consume up to 40% of energy compared to electric systems. |
| Control precision | average | Pneumatic devices have a deviation of up to ±5%. |
| Air consumption | High | The system can consume up to 200 l/min per device. |
| Service cost | High | Regular replacement of filters and manifolds. |
| Specialized requirements | low | Additional infrastructure is required for pneumatic systems. |
Modern alternatives
Electric electric motors provide higher accuracy, energy efficiency and ease of use. Below is a comparison of the old and new technology:
| Indicator | Pneumatic system | Electric motor |
|---|---|---|
| Efficiency | 40% | 85% |
| Control precision | ±5% | ±0.5% |
| Energy consumption | 200 l/min | 1.5 kW |
| Service cost | €150/month | €50/month |
| Specialized requirements | High | low |
Calculating ROI
Return on investment (ROI) can be calculated using the following data:
Energy consumption: Replacing 100 devices from pneumatic to electric motors will reduce energy consumption by 45 kWh. At a price of €0.15/kWh, this will result in annual savings of €6,500.
Maintenance cost: Replacing devices will reduce the maintenance cost from €15,000 to €5,000 per year, resulting in annual savings of €10,000.
Downtime Reduction: Increasing Control Accuracy will reduce downtime by 15%. With an average consumption of €100/hour, this will result in annual savings of €15,000.
Total annual savings: €31,500.
Cost of implementation: €40,000.
Payback period: 1.28 years.
Implementation plan
The update should be performed in phases to minimize the impact on production:
- Planning: Identify critical devices and perform cost analysis.
- Order: Purchase new electric motors with UNITEC-D E-Catalog.
- Installation: Replacement of old devices with new ones taking into account technical specifications.
- Commission: Testing and confirmation of compliance with standards.
Technical challenges
The following problems may occur during implementation:
- Incompatibility of interfaces: Using VICKERS DGMPC5-ABK-BAK- as a modern alternative ensures compatibility with existing systems.
- Energy infrastructure: It is necessary to upgrade the power supply to 380 V.
- Service: Possible need for staff training.
- Modernization: Using UNITEC-D E-Catalog ensures reliability and compliance.
Use case
In the production enterprise of 100 devices, pneumatic systems were replaced with electric electric motors. After update:
- Efficiency: Increased by 45%.
- Accuracy: Reduced to ±0.5%.
- Maintenance cost: Reduced by €10,000 per year.
- Energy costs: Reduced by €6,500 per year.
- Specialized Requirements: Reduced by 60%.
Commission and inspection
After installation, the following procedures must be performed:
- Testing: Carrying out tests for efficiency, accuracy and compliance with EN 60204-1 and ISO 13849. standards
- Action: Confirmation of compliance with DSTU and CE requirements.
- Registration: Filling out documentation and obtaining UkrSEPRO certification.
Conclusion
Upgrading pneumatic control systems to electric motors is a critical step for manufacturing companies. The use of VICKERS DGMPC5-ABK-BAK- and UNITEC-D components ensures reliability, energy efficiency and compliance with standards. Go to the UNITEC-D E-Catalog for detailed information and technical support.
