1、 Inverter control of the high-efficient permanent-magnet motor
Inverter control can adjusting the rotary speed according to the
needed quantity of air and it can save more energy compared to the
machine without the inverter to control its rotary speed. Besides,
comparing with the general-used machine with an inverter, equipped with
high-efficient permanent-magnet motor can save the 6%~7% of the energy,
especially in the area of low loading, its outstanding control range
and structure can show obvious advantage in energy-conservation.
Compared with the common power frequency air compressor, magnetic
variable frequency air compressor which can play the highest energy
efficiency in a wide range will save the energy of 42%.
2、Decreasing the times of repair
It has equipped with the newest screw rotor which can be
semi-permanently used. It will not need a big scale of repair until 10
years later considering the best so that the customers’ needs on
long period of maintenance can be achieved. It has the oil quality of
high-efficiency and longevity and do not have the structure of suction
adjusting valve.
1. Have a stable operation
It does not have the mechanical loss caused by leather belt and
gear wheel. It has a compact structure. Neodymium boron permanent
magnet of high-efficiency is used in the permanent-magnet machine, it
will not lose its magnetism even under 120℃ and has a longer time of
usage. Corona resistant enamel covered wire specialized for inverter is
used in the stato coils, thus having a better capability of insulation
and a longer time of usage.
2. Controlling system of colorful touching screen
The controlling system is dynamic and fully intelligent, it can
dynamically show the working situation of every parts in the compressor
and can show the working curve of voltage and temperature in the
real-time and intuitive way. It has a super big internal storage of 8M
Flash ROM+16M SDRAM and can store thousands of historical failures. The
standard screen has TFT of seven inches. It have passed the CE
certification and accord with the FCC Class A. It can achieve the
intelligent control, speed changing control, automobile adjusting of the
air quantity, loading start-up, elimination of current surge and
lengthen the using time of composing parts, thus improving the
reliability of the system greatly.
3. Energy-saving and stable
High-efficient permanent-magnet motor is more energy-saving
compared with the common frequency-changed host machine, especially
under the condition of low rotary speed, the former one can still keep
a high motor efficiency. The responding speed of synchronous motor
is quite quick, it performs well in the exhaust response and can realize
the soft-start.The current of motor will not exceed the current of full
loading during operation and at the same time, it can reduce the pound
to the power grid equipment and will not cause the damage to the
electrical appliances.
4. Small size
The size of the motor is small. The size of common
frequency-changed motor is three times bigger than it so the dismounting
and mounting would be very convenient.
5. Inverter control of the cooling fan (optional)
The cooling fan is controlled by the inverter so that 50% of
the energy can be saved. The revolution of the fan is controlled
according to the exhaust temperature, thus saving the electricity. At
the same time, the durability is enhanced due to the temperature of the
system and whole parts have been stabilized. Besides, the noise can be
further decreased after the inverter have been used in the fan.
6. Avoiding the loss on unnecessary power
The pressure sensor can sense the pressure at the exhaust port
and then send the signal to the PLC, the PLC can control the output
frequency according to the value of pressure comes from the pressure
sensor. The frequency can be decreased when the voltage is big and the
frequency can be increased when the voltage is small, so that the
pressure can be always stable. The compressor can control the rotary
speed of the permanent-magnet motor by inverter, thus composing a
frequency-changed and loop-closed controlling system. Achieving the
stable voltage in air supply, using more then producing more,using less
then producing less, no using then stop and when using, then soft-start
to produce the air. Avoiding the loss on unnecessary power totally.
7. A wider range of working frequency and low noise
The frequency changes from 25% to 100%. The bigger fluctuation in
the system gas consumption, the more obvious of the effects in
energy-saving. Besides, the operating noise is small so that it can be
used in any situations.
