Control method for a dual-cylinder moisture removal apparatus

摘要

A control method for a dual-cylinder moisture removal apparatus of a pneumatic system is taught. The control method places a limitation on the time for drying of moist air in a drying cylinder. The drying of moist air in one drying cylinder and the regeneration of the absorbent used to dry moist air in a second cylinder are alternated at each predetermined time. When the air compressor is stopped each drying cylinder is switched to a reverse position to the position it occupied just prior to the stopping of the air compressor. Furthermore, when the air compressor resumes operation, the position of each drying cylinder is maintained in the position it occupied just before resumption of operation of the air compressor.
