How does the permanent magnet variable frequency air compressor save energy?

永磁-英.png


Frequency conversion air compressors are made for energy saving, and the general production includes permanent magnet frequency conversion and ordinary frequency conversion. In the world of variable frequency air compressors, the most energy efficient is the permanent magnet variable frequency air compressor. Energy saving is only relative, and its ultimate purpose is to save money, so the meaning of "energy saving" of permanent magnet variable frequency air compressor is no longer single, and it even includes the maintenance and repair costs in the later period, so let's take a look now, How does the permanent magnet variable frequency air compressor save energy?


1) Energy saving effect of permanent magnet variable frequency air compressor


The biggest advantage of the permanent magnet variable frequency air compressor is energy saving, generally 10%~35% energy saving, the amount of energy saving depends on the working conditions of the air compressor and the setting of the parameters of the frequency converter. The biggest factor is the working condition of the air compressor. When the customer's gas consumption fluctuates greatly, the energy-saving effect will be better. The most direct data is the proportion of the no-load time to the total working time. Therefore, in the process of selling the control cabinet of the inverter, we must first understand the customer's working conditions and obtain the following data:


The model of the machine; whether the working mode is ON/OFF control or MOD control; load working time and full working time;


The daily working hours of the air compressor, the number of days per week, and the number of hours in a year; the setting of the pressure band; if there is an electric energy meter, copy down the degree of electricity consumption. What is the local electricity cost per kilowatt hour.


After knowing the above conditions, it is possible to calculate how much money can be saved in a year when the high-efficiency energy-saving controller is installed. Of course, this energy-saving analysis is very complicated, and there is a special software TOOLBOOKS to calculate how much electricity can be saved under specific working conditions.


2) The maintenance cost of permanent magnet variable frequency air compressor is reduced


Due to the high-efficiency and energy-saving control system, the software start of the air compressor reduces the electrical shock to the electrical components of the motor, and the starting current is small, which prolongs the life of the contactor of the motor. Software activation of the air compressor reduces mechanical shock to the equipment, and motor bearings, main engine bearings and gearboxes all extend service life. The high-efficiency and energy-saving controller control device keeps the air compressor in a loaded state most of the time, and all kinds of related solenoid valves and pneumatic components greatly reduce the number of actions, so the failure rate of both electrical and mechanical parts is greatly reduced. Feeds the cost of replacement parts and labor.


In addition, the inverter control device keeps the air compressor in the loading state most of the time, and the air inlet filter is always in the forward filtering state. When unloading, the air filter is in the reverse filtering state, and the use of the inverter is greatly reduced. It shortens the reverse filtration time of the inlet filter and prolongs the service life of the filter element.


3) The permanent magnet variable frequency air compressor reduces the capacity of the power grid of the factory


When using star-delta starting, the starting current is still relatively large. When the factory grid capacity is limited, it will cause the upstream air switch to trip. The use of high-efficiency energy-saving controllers can save the cost of factory grid expansion.


4) Permanent magnet variable frequency air compressor reduces production loss


The permanent magnet variable frequency air compressor uses a high-efficiency and energy-saving controller, and monitors more than 20 parameters at the same time, such as current, voltage, speed, torque, power consumption, and the system is highly intelligent. Make the air system more stable and reliable, reduce downtime and production loss.


5) Permanent magnet variable frequency air compressor can reduce noise


When the exhaust volume is reduced, the speed of the motor is slowed down, and the noise of the air compressor is much less than when running at full speed. The time for unloading operation is reduced, and the noise of emptying is also reduced.


The five major advantages of permanent magnet variable frequency air compressors are almost all to reduce costs. So far, is this kind of air compressor enough to make you excited? It can not only reduce costs, save energy and protect the environment, but also reduce work efficiency and noise pollution. When choosing a permanent magnet variable frequency air compressor, you must ask the sales staff about the relevant energy-saving meaning, recognize the brand, and avoid buying counterfeit products and the loss is too large.
