Energy-saving assistance for variable frequency motor pumps
Thread Content
Everyone says that using variable frequency motors will save electricity and operating costs, but they don’t know where the savings are? Suppose I have a water pump that delivers water at a flow rate of 50m³ per hour and a head of 0.3MPag. Please help me analyze and select the model. It is best to have a comparative analysis between ordinary pumps and variable frequency pumps, and add a flow adjustment valve to the ordinary pump.
There is a lot of information saying that frequency conversion saves electricity, but what is the real effect? If it is really very energy-saving and the technology is mature, I think few petrochemical companies in China will refuse it.
