Heating speed of electric heater and treatment method of scale

Date:2017-07-01 Author:http://www.z-1.net.cn/ Click:

It depends on the structure of the heater. The frequency converter can only change the frequency of alternating current, so as to change the rotation speed of the motor and achieve the purpose of changing the output power of the motor. And the heater does not rotate, and the frequency can not control the heating speed.

There are two simple methods:

Diode half wave rectification is used to change the effective value of alternating current, so as to change the purpose of heating power and heating speed. This method is applied most, and its advantage is simple circuit structure and convenient operation.

Pressure variable, with a small transformer pressure, the advantages of multi - gear adjustment, the shortcomings of the circuit structure is more complex, high production cost.

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

In order to remove the scale, a scale inhibitor is developed. It can be applied to the pipe heater to soften the scale and achieve the cleaning effect.

Magnetization and anti scaling means to magnetize the water, so as to soften the scale, making it difficult to condense and not easily attached to the inner wall.

The anti scaling of ion rods is a new method of anti scaling. This method is generally chosen in some large heaters and central air conditioners.

The treatment of sodium ion softening refers to the use of a solvent containing sodium ions in the heat transfer liquid so that it can soften the scale and remove the scale.

One millimeter scale will reduce the heating effect of 10%, and the effect is very obvious. So we must clean up the electric heater in time after use, so as to prevent the problem of unnecessary failure when the next use is used.
