Ingersoll Rand CENTAC centrifugal oil-free air compressor

To meet the needs of industrial development, since 1911, the United States has been engaged in Ingersoll Rand centrifugal air compressor design and production work, and always maintained a leading position in the world. With years of experience in production and design capabilities and finally in 1968 built the first CENTAC brand centrifugal air compressor production line. Since that date, more than 2,000 units CENTAC unit operating in the world in various fields of industry

Well-rotor
A typical single axle wheel design to shorten the length of the rotor, to minimize the weight of the boom, so that the rotor has the best combination of stability. Impeller and diffuser gap between the work from the air or water temperature change
Semi-open three-dimensional flow backward curved impeller (originally developed by the Rand Corporation) and the unit has the best control, while allowing maximum operating range
CENTAC impeller made of special high-pressure casting cast stainless steel by forming a dense, high strength and corrosion resistance characteristics

Thrust ring effective aerodynamic thrust disperse transmitted to the chassis, so that the main gear does not bear the load, the maximum extent possible to extend the life of the gear
Unique arc triangle fraction ensures thrust ring, impeller and pinion self-locking connection between the firm and make disassembly is very simple. This arc triangle connection also increased the contact area, compared with keys or hot sets of connections, longer life

Superior mechanical transmission
CENTAC rotor assembly optimize efficiency, ensuring reliability, and simplify maintenance
Stable pinion stub shaft so that it can adopt a simple structure fixed three-tile set of simple bearings. The bearing has no moving parts, no annual maintenance
Bearing all the conventional low-pressure lubricating oil system, lubrication, in order to achieve an effective gear lubrication and film stability. Oil from the installation on the main oil pump shaft and is equipped with a computer-assisted pump

Axial thrust is small, one-way, and can be predicted to minimize energy consumption. Minor thrust side of each gear by a fluid dynamic pressure bearing absorption
Standard radial and axial thrust bearing no moving parts. This simple structure can be passed-shaft bearing on the operation of effective monitoring, and thus eliminates the need for regular maintenance time and costs

Efficient heat
CENTAC unit, the air in the tubes and water management, air cooler has the following main features
Contact surface with water --- gas - is out of reach double tube cooler, so that the cooling effect is better, lower temperature, and after the scaling caused by deterioration of machines running less likely smaller. thus reducing the flow of cooling water cooler and maintenance workload.
The design avoids the intercooler piping hot out of the air compressor connection problems. In CENTAC design of exposed pipes, avoiding the use of expensive pipeline expansion joints. Water management, but also plays the role of air noise isolation
CENTAC air cooler may recoil at run time, or on-site cleaning. Both methods minimizes the downtime required for cleaning cooler

Overall assembly design
CENTAC the overall assembly design has many advantages, but the main advantage is simple structure. Completely assembled CENTAC compressor and piping on the main components in the factory had installed, which makes on-site installation work is very simple. And tight beat structure also eliminates a lot of your time and money
