Heating speed of electric heater and scale treatment method

This depends on the structure of the heater, the inverter can only change the frequency of alternating current, thus changing the rotation speed of the motor, to achieve the purpose of changing the output power of the motor. The heater does not rotate, and the frequency of the heater does not control the heating rate.

There are two simple ways:

1. using diode half wave rectification to change the effective value of alternating current to achieve the purpose of changing heating power and heating speed. This method is the most widely used and has the advantages of simple circuit structure and easy operation.

2. the transformer is changed by a small transformer, and the utility model has the advantages that the utility model can be adjusted by a plurality of gears, and the disadvantage is that the circuit structure is complex, and the manufacture cost is high.

How to deal with the scale problem of pipeline electric heater:

1, pharmaceutical cleaning, aiming at the composition of scale, developed a kind of anti fouling agent, added to the pipe heater, can soften the pipe heater in the scale, and to achieve the effect of cleaning.

2, magnetization, anti fouling, refers to the water quality magnetization, thereby softening scale, so that it is not easy to coagulate, it is not easy to attach to the inner wall.

3, ion bar anti fouling is now emerging anti scaling methods, and now some large heaters, central air-conditioning is generally chosen in this way.

4, sodium ion softening treatment, refers to the use of sodium ions containing solvent in the heat transfer fluid, so that it will soften the scale and remove the effect of scaling.

One millimeter of scale will reduce the heating effect by 10%, and the effect is very obvious. So after we use, we must clean the pipe electric heater in time, in case the unnecessary trouble will appear in the next use.
