Nota:
Observaciones sobre el número de modelo: “F” significa velocidad fija, “V” significa VSD. Debido a las posibles diferencias en las velocidades de rotación de los motores, los caudales de aire de velocidad fija representan el mínimo del rango (es decir, 30 kW, 8 bar, 5,67 m³/min), mientras que el VSD puede alcanzar el máximo a plena carga.
Voltaje estándar en 380 V (+/-101 TP3T), 50 Hz +/-21 TP3T y disponible para voltajes personalizados de 220/380/440/460 V/60 Hz.
En casos de altitudes elevadas, temperaturas extremas, humedad excesiva, exposición intensa al polvo o cualquier otro entorno operativo difícil, podemos ofrecer diseños de productos personalizados para satisfacer sus necesidades específicas. La personalización está disponible para adaptarse a sus requisitos únicos.
Core Component Highlights of theCentrifugal Air Compressors
Rotor
The high-speed rotor is dynamically balanced, and designed to resist vibration without thrust bearings. There is no relative sliding in the rotor transmission, and the gear drive system is highly reliable, with a design life of 35 years.
Rodete
● Aviation class high efficiency and high reliability titanium alloy impeller
● Anti-corrosion special coating impeller used for high corrosion industry
● Five-axis precision machining forging 3D flow back leaning design impeller, higher aerodynamic efficiency
● Splitter blade design for large flow
● Low flow loss and better adaptability for off-design conditions
Bearings
● Tilting pad journal bearing realize high-speed and stable operation. Pad tilt will self-adjust when the bearing load changes.
● CC pad of high heat conductivity and high strength can decrease the bearing temperature and promote the stability of the rotor system.
Highly Reliable Cooler
● Straight tube design, no need to be pull out when maintaining, 90% maintenance time saved;
● No consumption parts and low maintenance fee;
● Larger design, high heat exchange efficiency, low water consumption and low pressure loss, about 1-2% energy saving;
● Gradual changing Cross design, perfect gas-liquid separation effect;
● Stainless steel backing board design, eliminating corrosion risk;
● No fastening parts, no risk of dameging the impellor by fallen parts;
● Supported by both side, eliminating the damage risk from resonance;
● Long life span drainer, no rusty, draining strongly and zero gas consumption.
Caja de cambios
Horizontal split type for easy maintenance of the bearings and shaft seals.
Thrust collar instead of thrust bearings. Which makes the structure simpler and increase the transmission efficiency and reliability.
Local Control System
● The advanced Siemens PLC system +7” touch screen, friendly interface and easy opeartion;
● Options for auto dual, constant pressure control and self-balance control mode;
● All operating parameters can be displayed and setted；
● Features for various alarm and trip condition；
● Features anti-surge and surge prediction functions；
● Communication to DCS by DH+, Modbus, Profibus OR Ethernet.
Inlet Guide Vane
The efficiency of compressor with IGV is 7-9% higher than that with butterfly valve, for IGV provides preswirl flow to the air taken into in the same direction as the impeller. Furthermore IGV can provide wider turn down rage and which is more smoothly during the adjusting period.
● Smoothly and high efficiency when adjusting;
● More safety and dust proof with cover;
● High reliability by fork type.
Air Seal
The gas & oil seal is labyrinth type, which has no contact to the shaft., no abrasion, long life, and low maintenance, no consumption of instrument air, and also, horizontal split makes easier maintenance.

Preguntas frecuentes
What are the advantages of using a centrifugal air compressor?
Centrifugal air compressors are known for their high efficiency, reliability, and low maintenance requirements. They are ideal for applications that require a large volume of compressed air at a constant pressure, such as in industrial settings. The centrifugal air compressors are also quieter and more energy-efficient than other types of compressors.
How do I choose the right size centrifugal air compressor for my needs?
The size of the centrifugal air compressor you need depends on your specific application and the amount of compressed air required. Factors such as the size of your facility, the number of users, and the type of equipment being powered by the compressor all need to be considered. Consulting with a professional air compressor supplier or technician can help you determine the appropriate size and capacity for your needs.
How often does a centrifugal air compressor need maintenance?
Centrifugal air compressors generally require less maintenance than other types of compressors, but they still require regular upkeep to ensure optimal performance and longevity. A typical maintenance schedule includes regular oil and filter changes, inspection of bearings and seals, and checking for leaks or other issues. The frequency of maintenance will depend on factors such as usage, environment, and manufacturer recommendations. Consulting with a professional technician can help you establish an appropriate maintenance schedule for your compressor.
A continuación, compruebe el nivel de aceite y busque fugas u obstáculos alrededor de la máquina. Si se trata de una máquina refrigerada por agua, abra la válvula de agua de refrigeración y la bomba, y confirme que la presión del agua es normal. Por último, encienda la máquina y póngala en marcha. Si ha estado parada durante un tiempo, arránquela unas cuantas veces antes de hacerla funcionar continuamente para evitar averías innecesarias, como sobrecalentamiento o sobrecarga.
