The use of frequency converters in sulfuric acid
Thread Content
We are using a feed water pump with a pressure of 60 kilograms and a flow rate of 25 tons; the actual amount of water used is around 14.5 tons. Will installing an inverter help to save electricity and energy? Is there any company that has used this approach?
It can help save electricity; if new installations do not require control valves, there is no increase in investment either
Energy savings can be achieved; devices with a load of over 90% should not be installed, as the energy savings in such cases are minimal. The energy-saving effect of the equipment that uses a large motor to drive a small vehicle is significant after installation. Our unit started using variable frequency control as early as the year 2000.
Changing the frequency will reduce the pressure at the pump outlet; it is also necessary to replace the motor with an inverter-driven motor.
A variable-frequency motor can be created by adding a frequency converter to a regular motor!
Using a frequency converter can help save energy when the operating load is below 80%. It should be noted, however, that it is incorrect to assume that simply adding a frequency converter to a regular motor makes it a frequency converter motor; the cooling fan of a frequency converter motor is separate, and its speed does not change as the frequency changes. Especially in summer, to prevent motors from burning out due to overheating.
What was said upstairs is correct; a variable-frequency motor is not just an ordinary motor with an inverter added to it. A regular motor connected to an inverter will burn out.
I’ve benefited from it; it seems what you said makes sense. But why don’t the variable-frequency motors on site all have separate fans? ! ! Don’t doubt that I saw it wrong!

What organization do you work for? Is there a before-and-after comparison effect?
