Is there a special inverter for air compressor?

No, and there is no need to be dedicated; General inverters can be used, but pay attention to power matching when choosing.

No! Generally, as long as the power is right, it will do!

The power of the air compressor motor is generally large, and the starting mode mostly adopts no-load (unloading) star-delta starting, and the loading and unloading modes are instantaneous. This makes the air compressor have a large starting current when starting, and the mechanical impact on the equipment during loading and unloading is greater; It not only causes fluctuations in the power supply voltage, but also causes large fluctuations in the compressed air source; At the same time, this mode of operation will also accelerate the wear and tear of the equipment and reduce the service life of the equipment. Because the drag motor of the general air compressor itself can not regulate the speed, it can not directly use the change of pressure or flow rate to achieve the matching of the output power of the speed reduction, and the motor is not allowed to start frequently, resulting in the motor still having to run without load when the gas consumption is small, and the power is wasted hugely.

The frequency conversion transformation of the air compressor can make the motor achieve soft start and soft stop, reduce the starting impact, and prolong the service life of the equipment; At the same time, due to the variable operating frequency of the motor, the air compressor automatically adjusts the speed of the motor according to the size of the air consumption, reduces the frequent loading and unloading of the motor, thereby greatly reducing the running power of the motor, and makes the air pressure of the air supply system remain constant, so that the purpose of energy saving can be realized.

1. The air compressor is generally selected according to the actual needs of the design working conditions.

Under normal circumstances, the compressor is operated all year round, spanning the two extreme weather of winter and summer, so it is faced with a relatively complex external environment, and there is inevitably a certain deviation between the actual working conditions and the design scheme, so the compressor power will have an appropriate surplus.

2. At this stage, the energy regulation of air compressor mainly includes intermittent control operation, suction adjustment, cylinder unloading, bypass adjustment and stepless variable speed adjustment.

Among them, intermittent operation of air compressor is a more common operation mode, the ambient temperature is higher than the set temperature, the compressor will start running, and the ambient temperature will drop below the set temperature, and the compressor will stop working.

This working method is suitable for the situation that the ambient temperature is relatively stable and the load is not large, but in the actual use process, the ambient temperature is not constant at any time. In extreme weather and complex working environments, various production activities will cause changes in cooling loads, frequent temperature changes, and frequent engine starts and stops, which will cause large energy waste and easy wear and tear on machine parts.

Third, the instantaneous current of the generator will spread all over the power grid, increasing the fluctuation of the power grid, and the life of the compressor will also be affected.

Fourth, under certain working conditions.

The cooling capacity of the compressor is proportional to the mass flow, and the basic idea of frequency conversion adjustment is to adjust the mass flow rate by changing the speed of the compressor motor, so as to change the cooling capacity of the total unit.

Therefore, it is not difficult to see that the air compressor plus the frequency converter, and the use of the frequency converter to effectively adjust the frequency of the air compressor, whether subjectively or objectively, is very worthwhile. It not only saves resources to a certain extent, but also improves the work efficiency of the air compressor system, which can bring more benefits to the enterprise.

The differences between inverter air compressor and power frequency air compressor are as follows. Tianshui Jufeng LGY-13 7G electric mobile screw air compressor is recommended for screw air compressor, which has reliable operation, long life, and an overhaul interval of up to 4-80,000 hours. Tianshui Jufeng LGY-13 7G electric mobile screw air compressor is small in size, light in weight and occupies a small area, and is widely used in mining, water conservancy, transportation, shipbuilding, urban construction, energy, military and other industries.

The power frequency air compressor is the use of 50Hz alternating current of the national grid standard, which is fixed and immutable, and the speed of the main engine is also immutable. Frequency conversion is to install an inverter on the basis of the power frequency machine to realize frequency conversion, the frequency can be large or small, and the frequency modulation is used to control the speed of the host. Achieve the effect of energy saving, power saving and no no load.

Air compressor frequency conversion: the frequency conversion speed regulation system takes the output pressure as the control object, and the closed-loop constant pressure control system is composed of the inverter, pressure sensor and motor, the working pressure value can be directly set by the operation panel, and the on-site pressure is detected by the sensor, converted into 4 20mA current signal and fed back to the inverter, and the inverter is compared and calculated through the built-in PID, so as to adjust its output frequency to achieve the purpose of constant pressure air supply and energy saving of the air compressor.

Summary. Hello, Know-it-all has inquired for you: this one, generally speaking, it should be their scope of work is different.

The power frequency driven air compressor can only work in one exhaust volume, and the inverter air compressor can work in a wide range of exhaust volume.

That's the answer you're looking for

That's how it should be. The above is my consultation on this time, if there is anything unclear, you can communicate again, I hope it will be helpful to you

The air compressor can be divided into power frequency air compressor and frequency conversion air compressor, power frequency air compressor is also called fixed frequency air compressor, frequency conversion machine can have permanent magnet frequency conversion air compressor and alternating current frequency conversion machine, generally below 75kw containing 75kw is permanent magnet frequency conversion air compressor, 90kw containing more than 90kw are used AC frequency conversion machine.

1. The role is different.

Frequency conversion is to change the frequency of power supply, so as to adjust the load, reduce power consumption, reduce loss, and extend the service life of equipment.

Power frequency refers to the rated frequency used in power generation, transmission, substation and distribution equipment, as well as industrial and civil electrical equipment in the power system, in hertz Hz.

2. The impact is different.

Different frequencies have different effects on all aspects of power supply to the power grid, usually the frequency of a country's power grid is fixed, and all manufacturers of electrical equipment for this country and region must make equipment according to this frequency in order to use it normally.

The core of frequency conversion technology is the frequency converter, which realizes the automatic adjustment of the motor speed rate through the conversion of the power supply frequency, and changes the fixed grid frequency of 50Hz to the change frequency of 30-130 Hz.

3. The working principle is different.

A power supply device that generates high power frequency AC voltage. The device is often used for various power frequency high voltage tests, and can also be used as an AC high voltage power supply for DC high voltage generators, impulse voltage generators, inrush current generators and excitation power supplies for series resonant devices.

The power supply voltage adaptation range reaches 142-270V, which solves the problem of affecting the work of electrical appliances due to the instability of the grid voltage. The technology of alternating current control by changing the alternating current frequency is called inverter technology.
