Is the permanent magnet inverter air compressor good, and is it different from other air compressors

Comparison between permanent magnet variable frequency air compressor and ordinary air compressor:

Advantage 1: High efficiency and energy saving.

At full load, the permanent magnet motor of the permanent magnet variable frequency screw air compressor can produce the maximum gas volume under a small energy consumption; When the load factor of the permanent magnet variable frequency screw air compressor is less than 20%, the operating efficiency is always up to 95%, reaching level 1 energy efficiency. Compared with the power frequency screw air compressor, it is more energy-saving; Compared with ordinary inverter air compressor, energy saving is 10%.

Advantage 2: Durable and maintenance-free.

The permanent magnet variable frequency screw air compressor adopts a rare earth permanent magnet synchronous motor to directly drive the screw host, 120 without loss of magnetism, and the service life is up to 10 years. The screw host and motor of the permanent magnet variable frequency air compressor share the same spindle, which does not require belts and couplings, and has high transmission efficiency. The motor has no bearings, eliminating the failure point of the motor bearing.

Advantage 3: Provide gas volume according to demand, no no-load energy consumption loss.

Compared with the traditional control machine, the energy saving of the inverter-controlled compressor is the most practical, and the electricity expenditure is completely matched with the actual gas consumption, so as to achieve great energy saving.

For example, there is a customer who uses about 13 m3 min of gas, 6 m3 min of small gas, 60% load factor (load time and total working time), 6000 hours of operation per year, saving electricity: 6000h*(1-60%)*75kw*35%=63000kwh (not including 10%-13% loss caused by pressure loss).

The difference between permanent magnet variable frequency air compressor and variable frequency screw air compressor.

With the rapid development of industry and the gradual improvement of people's living standards, the society's requirements for the required products have been greatly improved. At the same time, upgrades to air compression systems have led to increasing requirements for the oil, moisture and decibel content of compressed gases. In this market environment, air compressors are used and loved by the public.

What are their advantages? What are the superior features, the following advantages are detailed for you below:

1.At the same power, the piston machine needs to consume some more electrical energy. Screw air compressors are relatively environmentally friendly and energy-saving.

The screw air compressor is equipped with sound-insulated cotton. Noise is lower than piston machines. At the same power, screw air compressors have a smaller footprint and are lighter.

2.The screw air compressor has a simple structure, long service life, and is easy to achieve large capacity and high pressure output. The disadvantages are high vibration and noise, and because the exhaust is intermittent and the output has pulses, an air reservoir is required.

3.There are two types of screw air compressors: twin screw and single screw.

The invention of the twin-screw air compressor was more than a decade later than the single-screw air compressor. The design of the twin-screw air compressor is more reasonable and advanced. The twin-screw air compressor overcomes the shortcomings of the unbalanced and fragile bearings of the single-screw air compressor, and has the advantages of long service life, low noise and energy saving.

The "environmental protection and energy saving" of permanent magnet variable frequency air compressor has always been a topic of concern to us. After years of continuous design and upgrading, the air compressor has also ushered in its energy-saving function, which has greatly improved the purchasing power of the air compressor and saved many industries from the trouble of using electricity.

1.The use of high-efficiency permanent magnet motor, compared with ordinary screw air compressor motor, more power-saving and more efficient;

2.The latest generation of integrated direct connection structure is adopted, which is more stable and more energy efficient;

3.Only frequency conversion technology, permanent magnet frequency conversion air compressor is up to 42% energy saving than ordinary screw air compressor;

4.Soft start feature to increase current balance and avoid current impact on the motor;

5.Eliminate the inefficient conversion process of ordinary screw air compressor from full load to unloading, and save energy by 10%-20%.

1. The power frequency starting impulse current is largeThe power frequency air compressor adopts the star delta starting mode, which starts at 5-8 times the rated current, which has a large impact on the power grid, which is easy to cause the instability of the power grid and threaten the operation safety of other electrical equipment.

2. The waste of electric energy is different between loading and unloadingAfter the pressure of a conventional air compressor reaches the required working pressure, the pressure will continue to rise until the unloading pressure is unloaded. For example, if the air compressor only needs 6kg of pressure, it must be hit to 8kg, and then loaded when it is reduced to 6kg, so there are two wastes, one is from 8kg to 6kg, the motor is idling, resulting in serious no-load waste, and the other is the waste of differential pressure from 6kg to 8kg.

3. The pressure is unstable and the adjustment is differentThe degree of automation of the power frequency air compressor is low, and the adjustment of the output pressure is realized by the control of the loading and unloading valve and the regulating valve, and the adjustment speed is slow, the fluctuation is large, the precision is low, and the output pressure is unstable.

Precautions for the use of air compressors.

The air compressor should be parked away from steam, gas and dust. The air inlet pipe should be equipped with a filter. Once the air compressor is in place, the spacer should be wedged symmetrically.

Always keep the outside of the tank clean. It is forbidden to weld or thermally work on the gas tank. The gas storage tank should be tested once a year, and the test pressure should be times the working pressure.

Barometers and safety valves should be inspected once a year.

Operators should be specially trained, must have a comprehensive understanding of the structure, performance and function of air compressors and ancillary equipment, and be familiar with the operation and maintenance procedures. The operator should wear work clothes, and the lesbian should tuck her hair braids into the work cap. It is strictly forbidden to operate under the influence of alcohol, not to engage in things unrelated to operation, not to leave the job without authorization, and not to decide to replace the work of non-local operators without authorization.

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.

Scope of application of frequency conversion:

1. Cable frequency conversion resonance device;

2. Generator AC withstand voltage device;

3. AC withstand voltage resonance device for electrical equipment of substation;

4. Resonant booster device for CVT inspection.

The start of the power frequency air compressor generally adopts the direct start or star-delta step-down start, which has a certain impact on the power grid. The air compressor driven by the inverter is inverter-driven, with a soft start function, and basically has no impact on the power grid.

The operation mode of power frequency air compressor is loading-unloading. The air compressor driven by the inverter can achieve constant pressure air supply according to the actual working conditions.

Hello, the main difference is 1. The lifespan is different.

From the perspective of the service life of the machine, the permanent magnet variable frequency screw air compressor is better. Due to the use of variable frequency drive, therefore, the air compressor is used in the start of the "soft start", which has a certain protective effect on the motor and reduces the possibility of burning the motor.

2. The parts are different.

From the perspective of parts, the permanent magnet variable frequency air compressor adopts a high-efficiency rare earth permanent magnet motor and a frequency converter. These two components are of great help to the energy saving of the air compressor.

3. The maintenance cost is different.

From the perspective of maintenance costs, permanent magnet motors do not need bearings and grease, eliminating failure points and reducing maintenance costs.

In addition, the permanent magnet inverter motor will automatically adjust the frequency to change the motor power according to the change of the user's equipment, which well matches the output power of the motor, and its working efficiency is still maintained at a high level in the case of light load or overload.

Hello Kiss is happy to answer this question for you. Scroll air compressor is a little better Advantages of scroll air compressor: 1. High reliability 2. Low noise 3. Low energy consumption 4. Low maintenance cost Disadvantages of scroll air compressor:

1. The surface of its moving parts is mostly in the shape of a curved surface, and the processing and inspection of these surfaces are more complicated, and some also need special equipment, so the manufacturing cost is higher. 2. Between the moving parts or between the moving parts and the fixed parts, it is often necessary to maintain a certain movement gap to achieve sealing, and the gas passing through the gap is bound to cause leakage, which limits the rotary compressor to achieve a larger compression ratio, therefore, most of the rotary compressors are mostly used under air-conditioning conditions. 3. The sealing requirements are high and the sealing structure is complex.
