特耐佳五金电器教您如何选择合适的电加热器,我从下面进行选择。

首先要考虑电加热器功率的大小。在满足时间参数的条件下,选择功率是为了满足加热介质所需发热量,是确保电加热器能实现加热的目的,正常运行的首选。

First of all to consider the size of the electric heater power. Under the condition of satisfy the time parameter, the choice of power is needed for calorific value in order to satisfy the heating medium, is to ensure that the electric heater can achieve the purpose of heating, the normal operation of choice.

由于电加热的热效率近似于1,可以这样认为:电加热器的功率即为发热量。

As a result of the electrical heating thermal efficiency is close to 1, think of it this way: the power is the calorific value of electric heater.

功率的计算选择应考虑以下三条:

The calculation of power selection should consider the following three:

⑴ 从初始状态,按规定时间要求实现加热介质至设定温度(工作温度);

(1) from the initial state, according to the rules of time for the heating medium to the set temperature (temperature);

⑵ 在工况条件下,发热量足以维持介质温度;

2 under the working condition, the calorific value is enough to maintain the medium temperature;

⑶ 应有一定的安全裕度,一般取1.2。

(3) should have a certain safety margin, average 1.2.

显然,从第⑴、⑵条选择功率的较大者,乘以安全裕度就是应选的功率。

Obviously, from the first (1), article 2 to select power supplied, multiplied by the power of safety margin is elected.
