Technical advantages of ledi permanent magnet variable frequency air compressor
1. In general, the gas demand of the user's pipe network will not always be in the saturated gas production state of the air compressor unit. When the gas consumption drops, through the frequency regulation of the frequency converter, the speed of the motor is reduced, the energy consumption is reduced, and the energy saving is realized. Permanent magnet motor is used to improve the efficiency of the motor. Permanent magnet can resist high temperature up to 180 degrees, never demagnetize!
2. Maximize energy saving and overall performance optimization
3. The advantages of this new product are to use the variable frequency air compressor alone or as the main engine to control other common air compressor units, fully improve the overall performance of the user's compressed air system, maximize the efficiency of air consumption, and ensure the constant pressure of the air pipe network.
The permanent magnet frequency converter can maintain the pressure stability of the pipe network system most accurately, and the most suitable application is the occasion where the gas consumption changes frequently, and the gas equipment which is sensitive to the pressure change.
5. The exhaust volume of permanent magnet inverter can be higher than the rated exhaust volume. If the user reduces the exhaust pressure, it can convert the surplus power into the power needed to produce more exhaust.
6. Permanent magnet frequency converter allows users to operate at a condition higher than the rated exhaust pressure, but its maximum exhaust volume will be reduced at this time. It converts the power originally used to produce part of the exhaust volume into the power required to obtain a higher pressure.
7. The frequency conversion unit adopts the cutting-edge vector control technology, so that the unit can obtain the appropriate torque to drive the air compressor in balance under the condition of the minimum temperature rise of the motor within the extremely wide speed range.
By using the new generation of ldpm series patented vector frequency conversion control technology, the high temperature resistance is improved, the conversion efficiency is higher, the energy consumption is saved and the reliability is improved
High power saving rate
30% energy saving on average
8. Maintenance cost greatly reduced
The frequency conversion air compressor reduces the impact on the equipment during operation, and the maintenance and repair amount is also reduced, so the maintenance cost is greatly reduced.
The unit will always maintain a constant pressure air supply of ± 0.1bar pressure; (completely avoid the loss of unloading power), improve the pressure control accuracy, and the constant pressure air supply will greatly improve the production efficiency and quality of the enterprise
9 to meet the user's requirement of setting the pressure in the range of 6-10 bar without changing gears or pulleys; (Note: to meet the customer's requirement of any different pressure)
10. Extend the service life of compressor
(1) , zero Hz soft start
(2) , smooth operation
Improve the operation efficiency of transformer and power grid
The current fluctuation at the moment of starting or loading of common unit will affect the power consumption of power grid and other equipment. The smooth starting and operation of variable frequency unit effectively reduces the peak value of starting current to the lowest level, so as to improve the operation efficiency of transformer and power grid.
11. Ultra low noise, low speed fan and scientific noise reduction design, suitable for living area
12. Detect air leakage
The operation frequency monitoring can detect whether there is air leakage loss at any time.
