YS-60AZ Air Compressor

Features of YS series double screw main engine and high efficiency permanent magnet motor drive

·The permanent magnet motor adopts high-performance NdFeB permanent magnet, 120c without loss of field, and its service life is more than 15 years.

·The stator coil adopts the special anti corona enameled wire for frequency converter. Excellent insulation and long service life. It can realize soft start, when running, the motor current will not exceed the full load current, at the same time, it greatly reduces the impact on power grid equipment, and will not cause damage to the electrical equipment.

·No motor bearing: the rotor with permanent magnet is directly installed on the extension shaft of the positive rotation. This structure does not need to use bearings, thus eliminating the fault points of motor bearings.

1. Working condition energy saving

Permanent magnet motor can maintain high efficiency at low speed, which ensures that it has obvious advantages of energy saving when the air consumption is small. The range of frequency conversion can be from 5% to 100%, and that of ordinary frequency conversion can be from 50% to 100%.

2. Ordinary variable frequency air compressor only saves energy consumption when unloading the system (variable frequency energy saving):

According to the fluctuation of gas consumption of fixed air compressor, there will be unloading time, which needs 45% of electric energy, while JM series is frequency conversion control, so there is no unloading and no waste. If the number of systems is more, the energy saving will be more.

3. Energy saving control the wasted electric energy of pressure bandwidth (frequency conversion energy saving):

In order to avoid the impact on the unit and power grid caused by frequent start-up of fixed air compressor, a minimum control pressure band of 1 bar (i.e. upper and lower limits) must be set. When several machines are used together, a pressure gradient is required, and the pressure band of the system is wider. The JF series is controlled by frequency conversion, which can start and stop indefinitely, so there is no need to set a pressure band, and a pressure band is set. The system can save 5% - 7% energy for every 0.14bar pressure band saved.

4. Save energy consumption during startup (frequency conversion and energy saving):

When the fixed air compressor is started, the current is about 3-6 times of the rated working current. If it is started frequently, a lot of electric energy will be wasted. There is no current impact in JM series starting, and it is soft starting. The maximum current does not exceed the rated working current, and there is no energy waste. At the same time, it also greatly reduces the impact on the power grid equipment and will not cause damage to the electrical equipment.
