delish machine26. July, 20250

Slitting machines achieve 20% energy savings usually through various technical optimizations and system improvements, the following is a detailed analysis of key parameters and implementation principles:

1. Motor system upgrade

parameter	Traditional equipment	After energy-saving renovation	Energy saving principle
Motor type	Ordinary asynchronous motor	High efficiency permanent magnet synchronous motor/servo motor	The efficiency of the permanent magnet motor is increased by 5%~10%, and the servo system adjusts the speed as needed to reduce no-load loss.
Factor	0.75~0.85	0.95 or higher	Reduce reactive power loss and reduce grid-side energy waste.
speed regulation method	Mechanical gearbox/frequency conversion speed regulation	Intelligent frequency conversion speed regulation	Dynamically match load demands to avoid energy waste caused by constant high-speed operation.

2. Cutting process optimization

parameter	The traditional way	Energy-saving methods	Energy saving principle
Cutting speed	Fixed high speed	Adaptive Shifting	Automatically adjusts the speed according to the thickness and hardness of the material, reducing idling and excessive energy consumption.
Tool design	Ordinary alloy cutters	High-precision wear-resistant coating tools	Reduced cutting resistance and reduced motor load (3%~5% energy consumption).
Tension control	mechanical tension	Closed-loop electronic tension control	Precise control of material tension to avoid friction losses caused by over-tightening (energy saving of about 2%~4%).

3. Standby and no-load losses

parameter	Traditional equipment	After energy-saving renovation	Energy saving principle
Standby power consumption	15%~20% of rated power	< 5% rated power	Equipped with an automatic sleep function, the power supply to the auxiliary system (such as hydraulics and air pumps) is cut off when the machine is stopped.
Proportion of no-load time	30%~40%	10%~15%	The material status is detected by sensors, and the speed is automatically reduced or stopped when there is no material.

4. Heat recovery and heat dissipation

parameter	Traditional design	Energy-efficient design	Energy saving principle
Heat dissipation method	Forced air cooling	Waste heat recovery system	The heat generated by motors and bearings is converted into preheating materials or workshop heating energy (energy saving 3%~8%).
Lubrication system	Regular manual lubrication	Intelligent centralized lubrication	Reduce friction losses and reduce drive power requirements.

5. Comprehensive energy efficiency management

parameter	Traditional model	Energy saving mode	Energy saving principle
Energy monitoring	No real-time monitoring	IoT energy efficiency analysis platform	Track energy consumption peaks in real time, optimize production schedules, and avoid operating during periods of high electricity prices.
Equipment linkage	Operate independently	Collaborative control (e.g. linked with slitting machine)	Reduce the number of starts and stops to balance the overall load fluctuations.

The path to saving 20% of electricity

1. Hardware upgrade (contributing about 50% energy saving):

◦ High-efficiency motor + frequency converter (energy saving 8%~12%)

◦ Low friction design (energy saving 3%~5%)

2. Intelligent control (contributing about 30% energy saving):

◦ Dynamic speed regulation + automatic start-stop (energy saving 5%~7%)

◦ Tension/temperature closed-loop control (energy saving 3%~4%)

3. System optimization (contributing about 20% energy saving):

◦ Heat recovery + production scheduling (energy saving 4%~6%)

Notes:

• Return on investment: usually 1.5~3 years (calculated based on the electricity cost of 0.8 yuan/kWh and the average daily operation of 16 hours).

• Maintenance costs: Permanent magnet motors need regular degaussing inspections, and intelligent systems need software upgrade support.

Through the superposition of the above technologies and refined control, the overall energy saving of the slitting machine is 20%, and in some cases it can even reach 25%~30% (such as with photovoltaic power supply). The actual effect needs to be evaluated in combination with the original energy efficiency level of the equipment and the production conditions.
