商品詳細介紹Product Introduction
The Fusheng SAV series employs a sophisticated and patented helical rotor tooth design. By combining a specially-made one-piece casing. an intelligent variable-frequency drive, and a control system, the Fusheng screw series compressor is able to feature high levels of efficiency, low energy consumption, and constant loading. It runs on 22kW to 220kW horsepower with a discharge volume ranging from 1.30m3/min to 42.0m3/min (operating pressures from 7.0kg/cm2G to 13.0kg/cm2G) and meets the international energy efficiency standards. The well-balanced, low vibration, quiet, and overall ergonomic designs enable easy maintenance and space planning, featuring the advanced and thoughtful design of the high-efficiency flow field in the cooling channel and high-precision oil filter. The specially designed variable-frequency drive and FUZZY output feedback control can automatically adjust energy consumption based on the actual operating conditions to save more than 30% of operating costs. The SAV series screw air compressor comes with a computerized self-diagnostic safety protection feature and it is an industrial grade compressor designed for wide industrial applications.
The Fusheng SAV series is verified by TUV Rheinland, a third-party testing laboratory. The design of the compressed air system is based on the five elements (the 5 S’s) that we want our products to provide for the customers - security protection (Safety), ease of Service (Service), stability and reliability (Stable), the international certification (Specification - compliant) and Energy Saving (Cost Saving).
Highly Energy-Saving Driven
● Simple structure for high reliability.
● Compact body design from coupling, motor bracker, motor to gearbox for 100% transmission efficiency.
● The amount of lubricant for bearings, compression chamber and gears are carefully calculated to minimize the oil resistance during compression and maximize the efficiency.
The Features of Air Compressor
High Efficiency Airend Induce Air Flow from Axial and Radial directions
● Fusheng's global R&D center in Germany is established with the aim to improve gear profile, volume efficiency and energy saving design and increase operating efficiency at low rpm.
●The axial air intake and exhausting design reduces axial imbalance effectively, and brings the following advantages for airend design:
- Lower operational noise level
- Longer service life of airend and bearings.
- Fully utilize effective rotor length to maximize the compression efficiency.
Highly Efficient Design
Intake Valve
One valve serves as non-return valve, shut-off valve and modulation control valve (optional). The low pressure drop design optimizes air intake efficiency. The compressor adjusts itself automatically with the actual need for compressed air as it operates, allowing for more accurate control of unload pressure and thus greater energy efficiency.
Independent Bearing
No more bearing lubrication by oil from secondary oil return pipe. The bearings are now lubricated by independent lubrication line. With the independent oil filter, the cleanness of lubricant is ensured.
Safe and high-efficiency air filter system
●The big particle size of dust in the vacuumed air will follow the air whirl and fall into the rubber slot at front end of air filter casing instead of attaching to clog the surface of filtration core.
●The long service life filtration core is designed with large filtration area and smaller resistance against air suction to ensure that the pure air whirl is without impurities.
●The independent air intake and filtration path allows the colder air is sucked directly from the outside, making the air intake denser for better efficiency.
All end faces sealed to completely remove the leakage
An environment-protective zinc-connector is mounted for connection and the end faces are sealed to completely remove the leakage
Vibration reducing device
The vibrations are reduced efficiently as the compressor is operating. It also prevents the propagation of low-frequency noises through resonance of solid objects while prolonging the compressor's service life.
Eco- and User-friendly idea
IE3 electric motor is used for all SA series screw compressor. It gives the compressor greater performance and better energy efficiency.
IoT smart real-time service system (optional)
The IoT compressor management system in the cloud platform realizes the unification of monitoring, malfunction diagnosis and servicing in one package. The messages of compressor malfunction and real-time status are sent to the designated professionals by SMS and email.
Unique cooling flow field for silence and efficiency
● With the
centrifugal fan, cold air is sucked in directly from outside to cool the cooler, and hot air is dissipated out from the top; With the greater heat transfer surface, the cooler ensuring excellent cooling effect.
● During cooler cleaning, simply remove the cover without dismantle the air duct and doors.
● In the electric control box, the colder air is drawn in directly to ensure the best heat dissipation.
● Independent air intake line in the motor ensures that colder outside air is drawn to the motor directly, and a silencing design is added at the intake port.
● For water-cooled models, heavy duty tube cooler is introduced for its large capacity and outstanding cooling effects, perfect for high-temperature environment.
● The compressed air flows through the line smoothly with virtually no pressure drop. Water flows through the inner tube and air in outer tube. The straight-through design makes cleaning very easy.
● Dual fan design, one or two fans are activated depending on the ambient temperature. This design is equivalent to the combination of cooling fans and additional " mechanical frequency inversion" (available for 90kW series above)
VSD Starting / Running
● Starting current is reduced.
● Starting current is eliminated for Y-Δ switching.
● Extending service life of compressor
Frequency inverting control for energy saving
● Variable-Speed air compressor can provide 30%~100% turndown range of capacity control. According to actual compressed-air demand of system to automatically adjust rotational speed of motor to meet the requirement. Providing optimum energy saving solution in variable loading management and reducing the operation cost up to 45%.
