What are the factors that cause the loss of the emulsifier

What are the factors that cause the loss of the emulsifier


The loss of the emulsifier includes no-load loss Po, short-circuit loss Pk and stray loss Ps. No-load loss, also known as emulsifier iron loss, refers to the hysteresis and eddy current of the material when the periodically changing magnetic field lines pass through the material, and its magnitude is related to the working voltage and tap voltage.


Short circuit losses are based on a specific pair of windings. It is caused by the resistance of the emulsifier windings and the load current flowing through the windings. Stray losses are losses that occur in conductors, enclosures, and other structural metal parts, and are related to the load. The no-load loss and short-circuit loss of the emulsifier account for most of the loss of the emulsifier.


When the primary winding of the emulsifier is energized, the magnetic flux generated by the coil flows in the iron core. Since the iron core itself is a conductor, an electric potential will be induced in the plane perpendicular to the magnetic field lines, forming a closed loop on the cross section of the iron core, generating a current, which is called "eddy current" because it is like an eddy current. Eddy current increases the loss of the emulsifying machine and increases the temperature rise of the iron core of the emulsifying machine.

The loss caused by "eddy current" is called "iron loss". In addition, the winding emulsifier requires a lot of copper wires, which have resistance and consume a certain amount of power when the current flows, and this part of the loss tends to be consumed as heat.

 

We call this loss "copper loss". Therefore, the temperature rise of the emulsifier is mainly caused by iron loss and copper loss.
