Why Mattei?
The Italian company Ing. Enea Mattei SpA is now recognized as a leader in the production of rotary vane compressors. The company was founded in 1919 by military engineer Enea Mattei after his return from World War I. Over the next several decades, it developed successfully, producing piston compressors. In the late 1950s and early 1960s, Ing. Enea Mattei decided to produce rotary compressors. Fruitful cooperation in creating the first series of industrial rotary vane compressors laid the foundation for the company’s production program and enabled it to occupy a leading position in the industry of rotary compressor production.
Over half a century of dedication to vane technology, constant investment in developing new models, perfecting production processes, using the latest technological equipment, and strict quality control, Ing. Enea Mattei has become one of the leading industrial air compressor manufacturers in Europe and has been able to compete with the most well-known brands in many markets worldwide.
Why rotary vane compressors?
The simplicity of the rotary vane compressor idea lies in the fact that the laws of physics in this design work almost automatically, without requiring the designer to come up with any special inventions. The blades themselves come out of the rotor ports under the influence of centrifugal forces, oil is injected into the compression chamber independently under the influence of internal pressure in the compressor, an oil diaphragm on the inner surface of the stator prevents metal-to-metal friction when the blades are tightly pressed against the stator wall and the flat front surfaces of the rotor are pressed against the stator front surfaces. Even the inevitable wear of the blade’s pressure edge does not worsen the compressor’s performance in the end, as it is compensated for by the centrifugal force itself. The oil diaphragm and tightly pressed blade create an ideal seal that prevents air from leaking from the high-pressure area to the low-pressure area and the associated loss of efficiency. With a larger compression range per revolution than a screw compressor and no internal leaks, high rotational speed is not required. The use of a low-speed motor with direct drive increases the reliability and service life of the compressor, and the absence of axial load eliminates the need for thrust bearings, which also contributes to a longer service life of the machine.
The elegant simplicity of the rotary vane design did not reveal itself immediately. It took about half a century of engineering research and entrepreneurial risk for the idea to gain a worthy technical reputation. And the following half-century of commercialization moved rotary vane technology into a series of leading compressor construction technologies. Today, rotary compressors are enjoying increasing demand in the general industrial air compressor market and in specific application areas.
The operating principles of a rotary vane compressor
The rotary vane compressor is a volumetric rotary compressor consisting of a cylinder – the stator, and a rotor – a massive metal cylinder placed inside the stator cylinder. The rotor is mounted eccentrically to the stator and has a smaller diameter, which causes it not to touch the inner surface of the stator with its surface along the tangential line during rotation.
The rotor cylinder has longitudinal slots in which blades are placed with the possibility of free sliding. The centrifugal force during rotor rotation pushes the blades out of the slots and presses them against the internal surface of the stator. In several sections of the compression chamber consisting of the stator, rotor, blades, and front covers, the volume decreases in the direction of rotor rotation, causing constant compression without pulsation.
The compressor is protected against leaks between moving parts thanks to efficient injection of compressor oil, which takes place at the expense of pressure difference between the compression chamber and the oil container. This oil serves both for cooling and lubrication purposes.
A constant thin layer of oil on the inner surface of the stator prevents direct contact of the blades with the stator surface and protects against wear.
Unlike a reciprocating compressor, in a rotary vane compressor, there are no axial loads that would press the rotor against the front covers of the stator. Therefore, there is no need to use thrust bearings to maintain the rotor in a fixed position, and instead, only two sliding bearings (babbitt bearings) are used on the rotor shaft, which have a practically unlimited service life.
During compressor operation, external air is drawn into the rotor-stator assembly through the inlet filter and inlet valve. The volume of the incoming air stream is adjusted according to the compressed air requirements by the inlet servo-modulating valve, which operates in a hydraulic circuit with the same oil that is used to lubricate the compressor.
