下面万森电器给大家介绍下电加热器使用原则与功能特点

电加热器外部元件在运用进程中,所要遵照的几个准绳:

1、首先要充沛的理解电加热器的运用温度要求,选择适宜的风道式电加热器设备。普通来说,功率越大,加热越快,升温的工夫也就越短,反之亦然。
2、电加热器设备严禁干烧,特别是侵入式电加热元件,而这类电加热元件都是采用的不锈钢为材料。
3、选择适宜功率的电加热管,在保证无效运用温度的前提下要留意功率的负荷成绩。
4、充沛的理解电加热管的运用环境,式介质传导还是红外线辐射等。
5、充沛的理解电加热器的接线方式,通常有星形接法和三星形接法,单条电加热管可以接220v或380v,多条电加热管可间接接380v。

空气风道加热器

电加热器功用特点:

1、体积小、功率大:加热器次要采用集束式管状电热元件。
2、热呼应快、控温精度高,综合热效率高。
3、加热温度高:加热器设计zui高任务温度可达850℃。
4、介质出口温度平均,控温精度高。
5、使用范围广、顺应性强:该加热器可适用于防爆或普通场所,防爆等级可达dⅡB级和C级,耐压可达20MPa。
6、寿命长、牢靠性高:该加热器采用特殊电热资料制造,设计外表功率负荷低,并采用多重维护,使电加热器平安性和寿命大大添加。
7、可全自动化控制:依据要求经过加热器电路设计,可方便完成出口温度、流量、压力等参数自动控制,并可与机算机联网。
8、节能效果明显,电能发生的热量简直99.99%传给加热介质。

 

 

The following wansen electric heater to introduce the use of principles and functional characteristics

 

In the process of using the external components of the electric heater, several standards should be followed:

 

1. First of all, it is necessary to fully understand the operating temperature requirements of the electric heater and select the appropriate air duct type electric heater equipment. In general, the higher the power, the faster the heating, the shorter the heating time, and vice versa.

2. The electric heater is strictly prohibited from dry burning, especially invasive electric heating elements, which are made of stainless steel.

3, choose the appropriate power of the electrical heating tube, in the premise of ensuring that the invalid operating temperature should pay attention to the power load performance.

4. Fully understand the application environment of electric heating tube, medium conduction or infrared radiation.

5. Fully understand the connection mode of electric heater, usually star connection method and three-star connection method, single electric heating tube can be connected to 220v or 380v, and multiple electric heating tubes can be connected to 380v indirectly.

 

Air duct heater

 

Functions and features of electric heater:

 

1. Small volume and large power: the heater adopts cluster tubular heating element.

2. Fast heat response, high temperature control accuracy and high comprehensive thermal efficiency.

3, high heating temperature: heater design zui high task temperature up to 850℃.

4, medium outlet temperature average, high temperature control accuracy.

5, wide using range, strong adaptability, the heater can be applied to blast or ordinary place, explosion-proof grade of d Ⅱ class B and class C, pressure of 20 mpa.

6. Long service life and high reliability: the heater is manufactured with special electric heating data, designed with low power load on the outside, and adopted multiple maintenance, so that the safety and service life of the heater are greatly added.

7, can be fully automated control: according to the requirements of the heater circuit design, can be convenient to complete the exit temperature, flow, pressure and other parameters of automatic control, and can be connected with the computer network.

8, energy saving effect is obvious, the heat generated by electrical energy is 99.99% to the heating medium.
