Permanent magnet variable frequency air compressor has many advantages. Why do you want to buy a power frequency compressor?
We first understand the advantages of permanent magnet variable frequency air compressor:
permanent magnet frequency conversion air compressor has become a hot spot and bright spot in the industry due to its energy-saving and high-efficiency characteristics. The original energy-consuming air compressor on the market is gradually being replaced or replaced by permanent magnet frequency conversion air compressor, which can directly bring users 20%-40% cost savings.
With the development of science and technology, air compressor as an important power equipment, is widely used in machinery, metallurgy, building materials, electronic power, chemical industry, food, textile and many other industrial fields. However, the air compressor is a high energy consumption equipment, in some industries, power consumption accounted for more than 30% of the production power consumption, so commonly known as "electric tiger".
Why permanent magnet variable frequency air compressor will be welcomed by the market? At present, the permanent magnet variable frequency air compressor in full swing has been widely used in industry, and it can not help but remind people of the power frequency driven air compressor. So, what is the difference between the two?
Stable 1. pressure
1. Because the variable frequency screw air compressor uses the stepless speed regulation characteristics of the frequency converter, it can start smoothly through the controller or the PID regulator inside the frequency converter. On occasions with large fluctuations in gas consumption, it can quickly adjust the response.
2. Compared with the upper and lower limit switch control of power frequency operation, the pressure stability is improved exponentially.
save power consumption
2. start without impact
1. As the inverter itself contains the function of soft starter, the maximum starting current is within 1.2 times of the rated current, which is very small compared with the power frequency starting at more than 6 times of the rated current.
This impact is not only on the power grid, but also on the entire mechanical system, which is greatly reduced.
3. variable flow control
1. The air compressor driven by power frequency can only work in one displacement, and the variable frequency air compressor can work in a relatively wide range of displacement. 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.
3. The optimized control strategy can further improve the energy saving effect.
Better voltage adaptability of 4. AC power supply
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.
If the fan is also driven by variable frequency, the noise of the air compressor can be significantly reduced.
Since there are so many advantages of permanent magnet variable frequency air compressor, why is there such a large market demand for power frequency air compressor?
In the process of continuous gas consumption, the permanent magnet frequency conversion air compressor is actually not much different from the power frequency air compressor, so when the gas consumption reaches a certain value, the permanent magnet frequency conversion air compressor is used together with the power frequency air compressor, which can well reduce the energy consumption of the enterprise.
Shanghai Granklin Group produces water-lubricated air compressor series products, including water-lubricated permanent magnet variable frequency air compressor and water-lubricated power frequency air compressor. From 5.5KW-250KW models have production, you can call at any time to customize your needs.
Single screw air compressor and twin screw air compressor difference in the world, in addition to the micro compressor, in the power with air compressor, more than 70% for the twin screw air compressor. Compared with the single screw air compressor, the performance of the new machine is not much different, mainly reflected in the performance difference after a period of use.
Granklin air compressor is suitable for laser cutting machine. Compared with traditional oil air compressor, water lubricated air compressor has higher gas purity. Laser cutting products are suitable for high-end industry processing, intelligent robots, etc. Water lubricated air compressor has high gas production and clean gas without oil.
There must be internal wear and aging during the long-term operation of the screw air compressor. Therefore, it is very important to regularly maintain and replace consumables in time. Most users are not very clear about consumables. The following is a detailed introduction of the consumables of the screw air compressor. What are the screw air compressor consumables we often say?
View detailsFrom the domestic and foreign high-end air compressor market, the head product of the screw type oil-free air compressor is still "imported air compressor", and there will still be a certain gap between domestic and foreign products, which is an unavoidable problem. We are lagging behind in technology. We have to catch up and move forward courageously and try to catch up with this missing technical barrier.
Business owners were confused about the choice of screw air compressor products in the early stage of factory construction, because during the factory construction process, they will definitely receive sample books from various manufacturers sent by many sales staff.

Shanghai granklin group co., ltd. specializes in air compressors. Air compressor accessories of various brands; Cold dryer, suction dryer (compressed air adsorption dryer achieves drying effect through "pressure change" (pressure swing adsorption principle). Since the ability of air to hold water vapor is inversely proportional to the pressure, a part of the dried air (called regeneration gas) is decompressed and expanded to atmospheric pressure. This pressure change makes the expanded air drier, and then allows it to flow through the desiccant layer to be regenerated without air flow (I. e. the drying tower that has absorbed enough water vapor). The dried regeneration gas absorbs the water in the desiccant, take it out of the dryer to achieve the purpose of dehumidification.
The water-lubricated air compressor produced by Shanghai Granklin Group is widely used as energy power in piling, tunnel sand blasting, pipeline pressure, oil drilling, mining, shipyard rust removal, nitrogen making machine matching, oil exploration, shale gas exploitation, exploration and other industries.
