Classed as an integral part of any air compression system, air receiver vessels act as reservoirs or storage vessels within air-powered systems. Applications for the apparatus abound throughout commercial venues and industrial facilities. Any hardware store worth its salt will have an aisle dedicated to the equipment, allowing curious engineers to size and grade the vessel for domestic tasks. On ramping up the scope of the equipment, industrial-grade air receivers are manufactured as high calibre products, container that can safely store air as compressed by a prime mover. Secondary design factors position the air receiving vessel as a buffer within a complex network of pipes, valves, filters and separator stages.
As concisely stated, a receiver vessel stores pressurized air and uses the container as a buffer, but these undefined facts could benefit from some fine detail. Firstly, let's define an area where industrial air compression is used. Pneumatic control systems, control and instrumentation frameworks that adopt spark-free operability, are preferred within hazardous environments. These systems utilize narrow tubes to deliver precise control to distant actuators. They also add supplemental ports within the system, interfaces where air-powered tools can plug in when work needs to be done. In fact, pneumatic signals are the preferred power source within many hazardous industrial settings. In these perilous locations, electrical circuitry is left safely ensconced behind reinforced control cabinetry while pressurized air manages valve opening operations and other control elements.
Having defined the usability factor that governs air compressor implementation, the design specifications of an air receiver vessel have to account for enough storage capacity to power remote pneumatic valves and air-powered tools. Those oil and gas refinery controls need a reliable control interface, a feat of engineering that can't be achieved unless the vessel is fabricated to partner with the compressor and the associated air conduits. The receiver can be mounted horizontally or vertically, but it must be sized to match the air compressor's operational characteristics. Additionally, the size of the installation, the equipment, type of valves, and all supplementary pneumatic equipment will affect the load characteristics of the vessel. Typical horizontal models adopt a low capacity profile, somewhere in the 25 to 325 litre range. Meanwhile, towering vertical containers can store substantially more air, holding between 100 and 1000 liters at a maximum work pressure of 1100 kPa.
A great deal of effort goes into the production of industrial air compressors, designs that incorporate reciprocating mechanisms or rotary screw constructs. Design calculations for the integral air receiving vessel are just as exacting. The designs are welded and fired to withstand extreme pressure. Oil and water is constantly tearing at the system, leading to the fitting of filters and drainage outlets, components that will take a hit on design calculations and volume requirements. These factors necessitate the addition of condensate drains and pressure gauges as dictated by Australian Standard AS-1210.
