High efficiency 300HP 250KW air compressor specifications for light industry

variable frequency air compressor advantage

One: Extend the service life of the High efficiency 300HP 250KW air compressor .The inverter starts the High efficiency 300HP 250KW air compressor from 0Hz, which can adjust the starting time of the air compressor, thus reducing the impact on some electrical components or mechanical components inside the High efficiency 300HP 250KW air compressor during starting, and enhancing the system. Reliability, extending the life of the compressor.

In addition, variable frequency control can reduce current fluctuations when the unit starts, which can affect the power consumption of the power grid and other equipment. The tr-crystal inverter effectively reduces the peak of the starting current to a minimum.

Second: High efficiency 300HP 250KW air compressor more reliable

1,Variable frequency soft start avoids electrical shock and avoids mechanical shock;

2,Exempt the unfavorable factors of long-term high-speed operation of the unit;

3, no contactor, to avoid electrical contact failure;

4, exempt 2bar high pressure, reducing the probability of system leakage.

Three: Reduce the noise of the High efficiency 300HP 250KW air compressor After installing the frequency converter, the speed of the motor is obviously slowed down in the required working condition of the compressor, and the noise generated by the air compressor is obviously reduced. According to the on-site inspection, the current noise is 3-7 decibels lower than the original noise.

Four: Energy saving and emission reduction Scientific development

The High efficiency 300HP 250KW air compressor has a one-year energy-saving recovery compared with the non-frequency conversion unit, and the energy cost of the entire inverter unit is recovered in three years!

variable frequency air compressor features

Since the speed of the High efficiency 300HP 250KW air compressor motor is in a one-time relationship with the actual power consumption of the air compressor, reducing the motor speed will reduce the actual power consumption. The variable frequency air compressor is a pressure sensor that senses the actual air pressure and air volume in the system.

Through the precise matching of electrical control and variable frequency control, the motor speed (output power) is instantly controlled without changing the torque of the air compressor motor (the ability to drag the load), and the system pressure is responded to by changing the compressor speed. The change and maintain a stable system pressure to achieve high quality compressed air on demand output.

When the system consumes less air, the compressed air provided by the compressor is greater than the system consumption. The High efficiency 300HP 250KW air compressor will reduce the speed and reduce the output compressed air volume; otherwise, increase the motor running speed and increase the compressed air volume to maintain a stable system. Pressure value. High efficiency 300HP 250KW air compressor the same as the power consumption of the fan motor pump. According to the load change, the voltage of the control input is the same as the principle of the inverter.

Its energy saving effect is as follows:

1,The pressure setting of the High efficiency 300HP 250KW air compressor can be one point, that is, the minimum pressure that meets the requirements of the production equipment can be used as the set pressure, and the High efficiency 300HP 250KW air compressor will adjust the speed of the High efficiency 300HP 250KW air compressor according to the trend of fluctuation of the pipe network pressure. Even eliminating the unloading operation of the air compressor, saving energy.

2, Because the High efficiency 300HP 250KW air compressor makes the pressure on the pipe network stable, it can reduce or even eliminate the fluctuation of pressure, so that all the air compressors in the system operate at a lower pressure that meets the production requirements, reducing the pressure upwards. Power loss caused by fluctuations.

3,Since the compressor cannot eliminate the possibility of long-term operation under full load conditions, the capacity of the motor can only be determined according to the maximum demand, so the design capacity is generally large. In actual operation, the proportion of time spent on light loads is very high. If the frequency conversion speed regulation is adopted, the working efficiency at the time of operation can be greatly improved. Therefore, the potential for energy saving is great.
