Advantages of permanent magnet variable-frequency air compressors
Permanent magnet variable-frequency air compressors use less electric energy to provide more compressed air and a wider capacity modulation range. At present, they are new energy-efficient air compressor models. The permanent magnet variable-frequency air compressor saves 15~38% of energy compared to power-frequency air compressors, and 5~10% of energy if compared with common variable-frequency air compressors. Moreover, the more dramatically the compressed air consumption of the system fluctuates, the more significant the energy-efficient effect will be. The most energy-efficient air compressors now are two-stage screw air compressors. They are the most advanced air compression equipment and have high air output, low noise, and low power. By contrast to single-stage screw air compressors, two-stage screw air compressors can save the energy by 50%.
1. An energy-efficient screw host machine
The host machine is of a well-known brand. Thanks to such an excellent machine, the compressor shows excellent performance on the whole.
2. An energy-efficient high performance motor
The high-performance motor is customized and provided with SKF heavy-duty bearings, and has an insulation grade F. Compared with like products, the efficiency is improved by 3~5%.3.An energy-efficient oil-air separator element system
With an efficient precision oil-air separator element, the system can effectively lower oil content in the exhaust of the compressed air and the power dissipation of the entire machine set. More particularly, the oil content merely reaches 1~2PPM.
4.A well-designed cooling system
An efficient heavy-duty air intake filter is adopted and ensures the inlet air quality for the compressor and the safety of the host machine. Hence, the service life of such equipment can be significantly improved.
5. An energy-efficient air intake control system
With a customized air inlet valve, air flows can be automatically adjusted in a range of 0~100% based on the system’s compressed air consumption demands, to reduce the corresponding operating cost.
6.An intelligent microcomputer control system
It is a Chinese/English control system easy to operate. This system can automatically run for 24 hours in an unattended condition. Besides, the system can be customized in other languages.
7.A frequency converter
The main electrical elements are all from internationally famous brands and contribute to significantly extending the service life of electrical apparatus.Design
1. An independent air inlet and exhaust channel
Independent air inlet can be achieved for the air filter, the motor, and the electric box. In this way, the heat in the box can be prevented from being sucked into the air filter or the motor and the intake of clean air can be ensured.
2. An efficient multi-step cooler
Stress deformation caused by cold shrinkage and thermal expansion of the cooler can be lowered; and the cooler is easy to dismantle, assemble, and change.
3. An oil-air bucket is provided with jacking rotation, which makes it convenient to repair and maintain.
The oil-air bucket cover is designed with jacking rotation. As all pipelines are in the bucket body, no pipe fittings are on the cover. In this way, relevant repair and maintenance can be conducted conveniently. No matter how big the machine is, one-man operation can be realized.
4.A temperature-controlled oil filter base is provided to avoid shutdown caused by jamming.
A flat seal temperature-controlled oil filter base for mixed flows is used to avoid the potential downtime caused by the jamming of the currently adopted divided-flow temperature-controlled piston valve.
5.Ultra-efficient
The compressor is provided with augmented rotors and features a low revolving speed, two-stage compression, a low-pressure ratio, high efficiency, and high reliability. The full range of our air compressors is ultra-efficient now.
6.A low-speed large-diameter centrifugal blower
The low-speed large-diameter centrifugal blower is simple in structure, can run efficiently and steadily, generates low noise, and shows a good heat dissipation effect. -

Application description
Rebar is the common name for hot rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar is composed of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words Hotrolled, Ribbed, and Bars respectively. Hot-rolled ribbed steel bars are divided into three grades: Grade II HRB335 (the old grade is 20MnSi), Grade III HRB400 (the old grades are 20MnSiV, 20MnSiNb, 20Mnti), and Grade IV HRB500.
