Answer: Whether the entire compressed air system can achieve the best energy efficiency is closely related to the selection of an air compressor of appropriate capacity. The basic principles are as follows:
(1) Be sure to ask the manufacturer of pneumatic equipment to provide air consumption and air consumption changes as the basis for analyzing and selecting air compressor capacity.
(2) If there are seasonal, time differences or other factors that affect the change in air consumption, a detailed assessment should also be made.
(3) Consider the overall foresight of the entire plant and list the estimated air volume for short-term, medium-term and long-term investment plans respectively.
(4) Do not insist on the concept that the type, model and capacity of air compressors must be consistent so that spare parts are interchangeable. In the case of a large range of air consumption changes, choosing a compressed air system with both large and small capacity air compressors can provide a more flexible response range and achieve unexpected energy-saving effects.
(5) If the compressed air system uses more than 3 to 5 air compressors, as long as the appropriate control method and peripheral equipment are carefully selected, there is no need to consider the configuration of large and small capacity air compressors to avoid the possibility of small capacity air compressors being idle.
The compressed air usage characteristics of various industries or factories are different, so the selection of air compressor capacity is quite complicated. How to correctly select the capacity of the air compressor is the right way to conduct a detailed evaluation in advance.
