Frequency inverters have been used extensively in the life and especially in industrial production such as crane control, elevators, industrial blowers ... in order to save electricity, increase engine efficiency, life expectancy. So how to use to ensure the longevity and safest?
ABB leads in the world
Benefits of using the inverter:
- High performance of the machine.
- The engine starts and stops smoothly, which helps to keep the engine life and mechanical components stable and longer.
- Safety, convenience and maintenance are also reduced, thereby reducing the number of employees servicing and operating industrial equipment.
- Power savings during start-up as well as operation.
- Fast payback period for engines running below designed capacity.
Use ABB inverter to save energy more efficiently
Note when using the inverter:
The temperature at the control room where the inverter is set should remain at 22ºC
- The inverter cabinet must be dry, free of corrosion or dirt.
- Inverter cabinet must have good ventilation or ventilation.
- Do not arbitrarily connect or change the parameters that engineers have established.
- Do not touch the machine when the machine is running due to the heat dissipation of the inverter when the engine can operate up to 800ºC.
- Do not touch the onboard components of the inverter.
- Do not allow metal to fall into the circuit board.
- Disconnect power before performing maintenance.
- When disconnecting power, electricity is still stored in the DC capacitor with high voltage, wait 15 minutes for the capacitor to discharge all stored energy, bringing the capacitor to the safety threshold before using again.
- Ground the inverter to prevent leakage
- Periodic maintenance is 2 years / time.
- The installation and maintenance of the inverter is relatively complicated, should use the team of experts, engineers have specialized and experienced.
Application specific inverter:
- Control of asynchronous motors from 15 to 600 kW at different speeds.
- Adjust the flow of the pump, air flow in the centrifugal fan, machine capacity, conveyor capacity.
- Stable flow, pressure at fixed level on the water pump system, blower, air compressor ... whether demand changes.
- Controls the start and stop process of the motor on the conveyor system.
- Small power inverter from 0.18 - 14 kW can be used to control working machines such as sawing, mixing, chopping, lifting, etc.
