1. permanent magnet variable frequency air compressor advantages introduction:
1. Stable air pressure
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. For occasions with large fluctuations in gas consumption, it can quickly adjust the response.
2. Variable flow control
the power frequency driven air compressor 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 gas consumption is low, the air compressor can also be automatically dormant, thus greatly reducing the loss of energy.
3. Start without impact
since the frequency converter itself includes the function of a soft starter, the starting current * * * is within 1.2 times of the rated current, which is very small compared with the power frequency starting, which is generally more than 6 times of the rated current. This impact is not only on the power grid, but also on the entire mechanical system.
4. Low noise
most of the working conditions of the frequency conversion system are lower than the rated speed, and the mechanical noise and wear of the main engine 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.
5. The voltage adaptability of AC power supply is better
due to the over-modulation technology used by the inverter, it can still output sufficient torque to drive the motor when the AC power supply voltage is slightly lower. If the voltage is slightly higher, it will not cause the voltage output to the motor to be higher. For self-generating occasions, variable frequency drive can show its advantages.
So as mentioned above, the permanent magnet variable frequency screw air compressor is really so "* * *"? Obviously not, let's take a look at the shortcomings of the permanent magnet variable frequency air compressor.
2. permanent magnet variable frequency air compressor shortcomings:
although the variable frequency air compressor is good, but because of its own composition principle, the user also has to bear certain risks in the process of using the permanent magnet variable frequency air compressor. Among them, the risk of * * * is degaussing caused by high temperature. We all know that permanent magnet motor in the element is magnetic steel, and magnetic steel is most afraid of high temperature. The permanent magnet variable frequency air compressor will gradually demagnetize under high temperature for a long time. The higher the temperature, the greater the risk of demagnetization.
There are many cases of permanent magnet air compressor function failure caused by magnetic steel demagnetization when using permanent magnet air compressor in various industries. Once the permanent magnet air compressor is demagnetized, the current of the motor will continue to increase after partial demagnetization, and the energy consumption will rise, which will increase the electricity cost of users. At the same time, there is the possibility of "* * *" of the motor at any time, which may seriously lead to scrapping the finished products of products.
In terms of energy consumption, frequency conversion air compressor is better than ordinary power frequency air compressor, so under the condition, we must choose the granklin frequency conversion air compressor of energy saving and environmental protection. Frequency conversion air compressor procurement must be based on the user needs of the air pressure and air flow, select the appropriate structure type of frequency conversion air compressor. The variable frequency air compressor has good mechanical properties (low vibration, low noise), good adaptability and stable operation.
Oil-free air compressor rubber ring can wipe the oil? This question granklin group's Shen for you to answer, oil-free air compressor is naturally not allowed to appear in the presence of lubricating oil in the accessories. Why can't oil-free air compressors have oil?
In the screw air compressor, unless it is a completely oil-free air compressor, lubricating oil is essential. Lubricating oil circulation screw air compressor & ldquo; whole body & rdquo;, mainly play three roles of lubrication, cooling and sealing. These all depend on the quality and performance of the lubricating oil itself. If the quality of the lubricating oil is affected, not only
The structure is reasonable and has ideal force balance: the screw of the oil-free air compressor is equipped with a star wheel symmetrical structure on both sides, so that the oil-free air compressor not only has no unbalanced inertial force, but also uses the axial force on the screw. The radial force also cancels each other out, making it ideal
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.
Shanghai granklin group is engaged in the production and processing of oil-free and water-lubricated air compressors. we are focused on the production of screw air compressors. doing a good job in water-lubricated air compressors can make mechanical failures lower and users feel more at ease in using gas. On the use of the effect to see the screw air compressor has the following advantages.
In the cold winter, because the temperature is low, once the air compressor does not pay attention to maintenance, it will cause the machine equipment failure. In winter, if the machine is shut down for a long time, there are not a few situations in which the cooling tower freezes and breaks and the body fails when starting.
A good brand of domestic oil-free air compressor, Shanghai granklin group provides you with a quotation for oil-free screw air compressor, which is a high-quality product and brand in the domestic air compressor industry. we sincerely invite peers who want to act as agents for oil-free air compressor and win-win cooperation.
View detailsBuy oil-free air compressor should pay attention to the point: buy oil-free air compressor to consider the safety of air compressor operation. Air compressor is a kind of machine with pressure work, accompanied by temperature rise and pressure, the safety of its operation should be put in the first place. National Air Compressor
The comparison between oil-free air compressor and oil-free air compressor can be expanded from the following dimensions: 1. Working principle Oil-based models During the compression process, the lubricating oil participates in the air compression and plays the role of heat dissipation and lubrication. The compressed oil-gas mixture is treated by the separator, and the oil content is passed through.
