Scroll compressor application scenarios

Official explanation of scroll compressor application scenarios

As a representative of positive displacement compression equipment, scroll compressors have formed differentiated application value in many industrial fields by virtue of their unique working principles and structural advantages. After systematically sorting out the industry’s practices and technical characteristics, we now make the following professional explanations on its core application scenarios and technical adaptability:

1. Basic technical principles
The scroll compressor forms a continuous change in the volume of the crescent-shaped compression chamber through the relative orbiting motion of the movable scroll and the fixed scroll, realizing the suction, compression and discharge of gas. This technical path eliminates the suction and exhaust valve components of traditional reciprocating compressors, significantly reduces mechanical friction and air flow pulsation, and forms the following technical characteristics:

1. Compactness: At the same power density, the volume is reduced by 40% and the weight is reduced by 15% compared to a reciprocating compressor.
2. Running smoothness: Inertial force balance design ensures that the vibration value is less than 0.5m/s² and the noise level is ≤52dB(A)
3. Energy efficiency: Volume efficiency reaches 92%-95%, which is 15%-20% more energy efficient than traditional models
4. Reliability: Critical component life exceeds 80000 hours, maintenance cycle is extended to 20000 hours

2. Core application scenarios

• Operating cost: 22% saves energy than piston unit, and reduces annual operating cost by 80,000 yuan (calculated by 8000 hours)

It is recommended that companies select models according to specific process requirements, focusing on pressure band matching, oil content control level and energy efficiency indicators. For new projects, it is recommended to carry out CFD flow field simulation to optimize the layout of the pipe network and reduce pressure losses. A preventive maintenance system should be established during operation to regularly detect vibration values, noise levels and temperatures at key parts, and achieve predictive maintenance through a digital operation and maintenance platform to ensure process quality while maximizing the overall efficiency of the equipment.
