| 风道式电加热器主要用于风道中的空气加热规格分为低温、中温、高温三种形式，在结构上的共同之处是采用钢板支撑电热管以减少电热管的振动，接线盒中都装有超温控制装置。另在控制方面除装有超温保护外，还在风机与加热器之间加装联运装置，以确保电加热器起动必须在风机起动之后，在加热器前后加一差压装置，以防风机故障，通道加热器加热的气体压力一般不应超过0.3Kg/cm2，如需超过以上压力，请选用循环式电加热器；低温型加热器气体加热最高温度不超过160℃；中温型不超过260℃；高温型不超过500℃。风道式电加热器用于工业风道、空调风道与各行业空气通过对空气的加热，提高输出空气的温度，一般在风道横向开口插入。根据风道工作温度分低温、中温和高温;根据风道内风速分低风速、中风速和高风速。 The air duct type electric heater is mainly used for air heating in the air duct. The specifications are divided into three forms: low temperature, medium temperature and high temperature. The common feature in the structure is that the steel plate is used to support the electric heating pipe to reduce the vibration of the electric heating pipe. The junction box is equipped with over temperature control device. In addition, in addition to over temperature protection, a combined transport device is installed between the fan and the heater to ensure that the electric heater starts. After the fan starts, a differential pressure device is added before and after the heater to prevent fan failure. Generally, the gas pressure heated by the channel heater should not exceed 0.3kg/cm2. If it needs to exceed the above pressure, please select the circulating electric heater; low temperature type The maximum gas heating temperature of the heater shall not exceed 160 ℃; the medium temperature type shall not exceed 260 ℃; the high temperature type shall not exceed 500 ℃. Air duct type electric heater is used for industrial air duct, air conditioning duct and air of various industries. The temperature of output air is increased by heating the air. It is generally inserted in the transverse opening of air duct. According to the working temperature of the air duct, it can be divided into low temperature, medium temperature and high temperature; according to the wind speed in the air duct, it can be divided into low wind speed, medium wind speed and high wind speed. |
