component electro-pneumatic electro-pneumatic operation
And got the following answer:
Air systems, regardless of compressor design or capacity, can operate more efficiently and economically through the proper selection and optimization of the control system used with the compressor unit.Compressor control systems have long had the ability to monitor and adjust basic air compressor functions, associated with monitoring, loading, unloading and throttling. Now, some systems provide additional features such as trend analysis, predictive maintenance schedules as well as remote monitoring and operations.compressor control systems function on a demand cycle. If the demand for compressed air is steady and does not fluctuate, compressor controls simply match the capacity to the system demand. One basic form of compressor flow control is called inlet throttling, or inlet unloading. Reducing the air flow is achieved by reducing the inlet opening through which the air enters the compressor. This, in turn, matches the compressor output to the system demand. Because system pressure acts a s a demand indicator, throttling is usually controlled by system pressure. However, most air systems are more complex and demand is more variable than the one described. Processes with complicated and varying demand cycles, which can include several compressors of different sizes and configurations to maintain system pressure, require a more sophisticated control system. The most common of these systems is the electro-pneumatic control system. More than 70 percent of all existing air compressors utilize electro-pneumatic control systems. These compressors feature electric and mechanically controlled devices -- such as pressure switches, solenoid valves and metering pins -- that adjust the loading and unloading through the use of an inlet throttle and/or a bypass valve. These control systems typically rely on mechanical pressure switches to monitor the compressor's proper discharge pressure. In addition, electro-pneumatic systems typically feature a series of mechanical trip switches that will discontinue compressor operation when pressures or temperatures reach critical levels.The electro-pneumatic action is a control system for pipe organs whereby air pressure, controlled by an electric current and operated by the keys of an organ console, opens and closes valves within wind chests, allowing the pipes to speak. This system also allows the console to be physically detached from the organ itself. The only connection was via an electrical cable from the console to the relay, with some early organ consoles utilizing a separate wind supply to operate combination pistons. Although early experiments with Barker lever, tubular-pneumatic and electro-pneumatic actions date as far back as the 1850s, credit for a feasible design is generally given to the English organist and inventor, Robert Hope-Jones. He overcame the difficulties inherent in earlier designs by including a rotating centrifugal air blower and replacing banks of batteries with a DC generator, which provided electrical power to the organ and drove the blower. This allowed the construction of new pipe organs without any physical linkages whatsoever. Previous organs all used tracker action, which requires a mechanical linkage between the console and the organ. The basic operation of the system is as follows: when the organist selects a stop and depresses a key, an electric circuit is completed, causing a low-voltage current to flow from depressed key, through the stop-tab switch, and on through the cable to the electro-pneumatic relay. The relay interprets the command from the console and sends an electric current to the appropriate solenoid. The solenoid is energized, causing the pipe valve connected to it to open, which emits compressed air into the pipe, allowing the pipe to speak. The system was an unqualified success. However, the single, most significant drawback to the system was in the massive amount of wiring required for operation. With each stop tab and key being wired, the transmission cable could easily contain several hundred wires! Add to this the great number of wires required between the relay and the organ itself, with each solenoid requiring its own signal wire, and you have a literal wiring headache, especially if a wire was broken (this was particularly true with consoles located on lifts and/or turntables), which made tracing the break a very difficult job at best. These problems were greatly amplified in larger organs, and it would not be unusual for a particular organ to have over a hundred miles of wiring in it. Even with these drawbacks, the action was functional, and many organists pronounced electro-pneumatic organs easier to play than tracker organs and faster, responsively, than tubular-pneumatic organs. In the years after the advent of the transistor, and later, integrated circuits and microprocessors, miles of wiring and electro-pneumatic relays have given way to electronic and computerized control and relay systems, which have made the control of pipe organs much more efficient. But for its time, the electro-pneumatic action was considered a great success, and even today modernized versions of this action are used in many new pipe organs.
