MULTIPLE CENTRIFUGAL AIR COMPRESSOR SYSTEM CONTROL

摘要

A multiple centrifugal air compressor system control (100) designed to maintain the optimum operating conditions for a centrifugal air compressor (105) operating in a compressed air system while still supplying compressed air at a selected pressure. The compressor system control (110) includes a source of compressed air (104), a storage vessel (100), several valves (115, 125) and at least one microprocessor (166) for controlling the operation of the system. The placement of at least one storage vessel between the source of compressed air and at least one back pressure control valve (125) allows the compressor (105) to operate at its optimum operating point without the compressor surging. A fast acting modulating control valve (115) attached to the storage vessel (110) also provides a vent to the atmosphere prior to the compressor's on-board controls venting the compressed air, and allows the compressor system to adjust the optimum operating point based upon ambient conditions.
