商品詳細介紹Product Introduction
The Fusheng SA series compressors are built with advanced patented helical teeth rotors and delicately processed one-piece casings. These rotary screw air compressors use premium technology to run efficiently and at low cost. They run on 5.5 kW to 220 kW of horsepower, have discharge volumes between 0.85m3/min and 42.0m3/min (operating pressure 7.0kg/cm2G), and meet 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 screw air compressor comes with an intelligent human-machine interface control system and a computerized self-diagnostic safety feature. It is an industrial grade compressor designed for wide industrial applications.
The Fusheng SA PLUS 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).
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.
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.●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.● 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)
Better noise control
Noise control is performed better now in SA series. Low-noise design is introduced to air filtering, independent air intake line of motor and cooling fans in addition to highly efficient vibration reducing device. Noises are minimized from the source.
Highly efficient, easy-to-maintain oil separator
● The supersized oil separator design features a large separation area that reduces the pressure drop during the air/oil separation while providing better filtration, thus making the compressed air system more efficient.
● A patented rotating shaft design is adopted on the separator cover. The replacement of oil separator is made much easier.
IE3 Ultra-efficient Motor
The combination of brand-new SA series and the IE3 ultra-efficient motor means not only full-scale performance improvement but also significant reduction in operating costs.
