Why choose compressed air to laser cutting machine?

Applicable materials:
Carbon steel, aluminum, aluminum alloy, stainless steel, brass, etc. below 2.5mm

Air supply pressure:13bar-16bar

Advantage:
Low cost, widely application

Laser cutting machine customer case:

A metal processing factory purchased 1 set of screw air compressor equipment to provide compressed air for a 500W fiber laser cutting machine.

If you use compressed air as the air source of the laser cutting machine, the cost will be relatively lower than using N2 or O2. A 500W laser cutting machine needs about 1 m3/min of 10-12bar compressed air, then a 7.5KW-11kw air compressor is enough. The electricity cost for such an air compressor to run for 1 hour is only about 5-8 kw`h, and the maximum electricity consumption for 8 hours a day is around 60 kw`h. One kw`h electricity is about $0.15/kw`h, then the total electricity cost will be $9, half to the oxygen cutting.

Let’s do a calculation, save $9 a day, work 300 days a year, save $2,700 in 1 year, and the cost of purchasing a complete set of screw air compressor can be recovered in less than 2 years. 
     
Therefore, using the compressed air for laser cutting will be the most economical solution, can help you save money and low down your production cost.

How does variable speed drive technology improve air compressor efficiency?

Variable Speed Drive (VSD) technology improves air compressor efficiency by allowing the compressor to adjust its motor speed to match the compressed air demand. This technology offers several benefits that contribute to energy savings and enhanced overall system efficiency. Here’s how VSD technology improves air compressor efficiency:

1. Matching Air Demand:

Air compressors equipped with VSD technology can vary the motor speed to precisely match the required compressed air output. Traditional fixed-speed compressors operate at a constant speed regardless of the actual demand, leading to energy wastage during periods of lower air demand. VSD compressors, on the other hand, ramp up or down the motor speed to deliver the necessary amount of compressed air, ensuring optimal energy utilization.

2. Reduced Unloaded Running Time:

Fixed-speed compressors often run unloaded during periods of low demand, where they continue to consume energy without producing compressed air. VSD technology eliminates or significantly reduces this unloaded running time by adjusting the motor speed to closely follow the air demand. As a result, VSD compressors minimize energy wastage during idle periods, leading to improved efficiency.

3. Soft Starting:

Traditional fixed-speed compressors experience high inrush currents during startup, which can strain the electrical system and cause voltage dips. VSD compressors utilize soft starting capabilities, gradually ramping up the motor speed instead of instantly reaching full speed. This soft starting feature reduces mechanical and electrical stress, ensuring a smooth and controlled startup, and minimizing energy spikes.

4. Energy Savings at Partial Load:

In many applications, compressed air demand varies throughout the day or during different production cycles. VSD compressors excel in such scenarios by operating at lower speeds during periods of lower demand. Since power consumption is proportional to motor speed, running the compressor at reduced speeds significantly reduces energy consumption compared to fixed-speed compressors that operate at a constant speed regardless of the demand.

5. Elimination of On/Off Cycling:

Fixed-speed compressors often use on/off cycling to adjust the compressed air output. This cycling can result in frequent starts and stops, which consume more energy and cause mechanical wear. VSD compressors eliminate the need for on/off cycling by continuously adjusting the motor speed to meet the demand. By operating at a consistent speed within the required range, VSD compressors minimize energy losses associated with frequent cycling.

6. Enhanced System Control:

VSD compressors offer advanced control capabilities, allowing for precise monitoring and adjustment of the compressed air system. These systems can integrate with sensors and control algorithms to maintain optimal system pressure, minimize pressure fluctuations, and prevent excessive energy consumption. The ability to fine-tune the compressor’s output based on real-time demand contributes to improved overall system efficiency.

By utilizing variable speed drive technology, air compressors can achieve significant energy savings, reduce operational costs, and enhance their environmental sustainability by minimizing energy wastage and optimizing efficiency.

Many modern air compressors utilize Variable Speed Drive (VSD) technology, also known as Variable Frequency Drive (VFD). This technology allows the compressor motor to adjust its speed according to the compressed air demand. By matching the motor speed to the required airflow, VSD compressors can avoid excessive energy consumption during periods of low demand, resulting in significant energy savings compared to fixed-speed compressors.

Air Leakage Reduction:

Air leakage is a common issue in compressed air systems and can lead to substantial energy waste. Modern air compressors often feature improved sealing and advanced control systems to minimize air leaks. By reducing air leakage, the compressor can maintain optimal pressure levels more efficiently, resulting in energy savings.

Efficient Motor Design:

The motor of an air compressor plays a crucial role in its energy efficiency. Modern compressors incorporate high-efficiency electric motors that meet or exceed established energy efficiency standards. These motors are designed to minimize energy losses and operate more efficiently, reducing overall power consumption.

Optimized Control Systems:

Advanced control systems are integrated into modern air compressors to optimize their performance and energy consumption. These control systems monitor various parameters, such as air pressure, temperature, and airflow, and adjust compressor operation accordingly. By precisely controlling the compressor’s output to match the demand, these systems ensure efficient and energy-saving operation.

Air Storage and Distribution:

Efficient air storage and distribution systems are essential for minimizing energy losses in compressed air systems. Modern air compressors often include properly sized and insulated air storage tanks and well-designed piping systems that reduce pressure drops and minimize heat transfer. These measures help to maintain a consistent and efficient supply of compressed air throughout the system, reducing energy waste.

Energy Management and Monitoring:

Some modern air compressors feature energy management and monitoring systems that provide real-time data on energy consumption and performance. These systems allow operators to identify energy inefficiencies, optimize compressor settings, and implement energy-saving practices.

It’s important to note that the energy efficiency of an air compressor also depends on factors such as the specific model, size, and application. Manufacturers often provide energy efficiency ratings or specifications for their compressors, which can help in comparing different models and selecting the most efficient option for a particular application.

Overall, modern air compressors incorporate various energy-saving technologies and design elements to enhance their efficiency. Investing in an energy-efficient air compressor not only reduces operational costs but also contributes to sustainability efforts by minimizing energy consumption and reducing carbon emissions.
