Permanent magnet variable frequency air compressor has been widely used in industry, and it can not help but remind people of the power frequency driven air compressor. Throughout the market, the power frequency driven air compressor has gradually withdrawn from people's attention, replaced by permanent magnet frequency conversion air compressor, so what is the difference between the two, why permanent magnet frequency conversion air compressor will be welcomed by the market?
1. pressure stability:
1, due to the frequency conversion of the screw air compressor using the frequency converter of the characteristics of the stepless speed regulation, through the controller or inverter internal PID regulator, can start smoothly; on the occasion of large fluctuations in gas consumption, and can quickly adjust the response;
2. Compared with the upper and lower limit switch control of power frequency operation, the stability of air pressure is improved exponentially.
2. start without impact:
1. As the frequency converter itself contains the function of soft starter, the maximum starting current is within 1.2 times of the rated current. Compared with the power frequency starting at more than 6 times of the rated current, the starting impact is very small.
This impact is not only on the power grid, but also on the entire mechanical system.
3. variable flow control:
1. The air compressor driven by power frequency can only work in one exhaust volume, and the variable frequency air compressor can work in a relatively wide range of exhaust volume. The frequency converter is based on the actual gas consumption to adjust the motor speed in real time to control the displacement.
When the air consumption is low, the air compressor can also be automatically dormant, thus greatly reducing the loss of energy.
The optimized control strategy can further improve the energy saving effect.
4. AC power supply voltage adaptability is better:
1. Due to the over-modulation technology adopted by the frequency converter, sufficient torque can still be output when the AC power supply voltage is slightly lower to drive the motor to work; when the voltage is slightly higher, it will not cause the voltage output to the motor to be on the high side;
2. For self-generating occasions, variable frequency drive can show its advantages;
3. According to the characteristics of the motor VF (the variable frequency air compressor works below the rated voltage in the energy-saving state), the effect is obvious for the field with low grid voltage.
Low 5. noise:
1. Most of the working conditions of the frequency conversion system are lower than the rated speed, and the mechanical noise and wear of the host are reduced, which prolongs the maintenance and service life;
2. If the fan also adopts variable frequency drive, the noise of the air compressor can be significantly reduced.
The difference between frequency conversion and power frequency is obvious. The energy saving advantage and efficiency advantage of permanent magnet frequency conversion air compressor are the necessary means to win the market.
What are the brand manufacturers of screw air compressor head? There are not many manufacturers that can sell air compressor head, especially water lubricated air compressor head. There are countless oil screw air compressor manufacturers in China, and the manufacturers that can independently produce water-lubricated air compressor muscles are phoenix hair and water chestnut. Screw air compressor head brand, the best domestic than Shanghai Granklin
View detailsFirst of all, the material of the machine itself does not contain oily substances, and there is no need to add any lubricating oil when working, so the quality of the discharged air is greatly improved, and the safety of the equipment required by the user is also guaranteed. Unlike an oil air compressor, the discharged gas contains a large amount of oil molecules.
Air compressors that can be used in medical systems need to be oil-free, and the air cannot contain any grease. In the production process of medicines and medical devices, air products containing oil and gas are unqualified.
View detailsIf the permanent magnet air compressor condensate is not discharged for a long time, it will cause rust inside the unit, reduce the effect of lubricating oil, and affect the operation of the air compressor. In summer, it will even cause the air compressor to start and stop constantly. So what is the basic principle of this air compressor?
High exhaust temperature is a common fault in the operation of air compressor. The long-term operation of the silent oil-free air compressor in a high temperature environment will accelerate the deterioration of the lubricating oil and seriously affect the displacement and service life of the unit. When the temperature rises too high, it will also cause high temperature shutdown failure
1. The air valve is leaking and the piston ring is worn too much. If the valve plate of the air valve is broken and the valve spring fails, it will cause the seal to be loose. In addition, the installation is not in place, the air valve is tilted, and the top rod plate on the valve cover is tight. The valve also causes the valve to leak and compressed air directly from the valve seat seal
How to distinguish oil-free air compressor is good or bad, reduce cost, energy saving and environmental protection, work efficiency and noise pollution is still very low. In the choice of permanent magnet variable frequency air compressor to choose a good oil free air compressor.
View detailsIn the field of food production, compressed air is the key power source and process medium, and its quality is directly related to food safety and product quality. In order to ensure that compressed air meets the high standards of the food industry, it is necessary to control the cleanliness, oil-free, microbial and other dimensions.
Localization of the air compressor can choose Shanghai granklin group, we produce water lubricated air compressor marketing throughout the country. Customization is acceptable. Choose high-quality permanent magnet motor to do a good job of energy saving, in energy consumption as much as possible for the user's production savings.
Air compressor as a new era of general equipment, whenever encountered gas demand, can not be separated from its figure. Let's take a look at the application fields of air compressor with granklin air compressor! Factory Dimension
