保定市电加热器厂

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 channel type electric heater is mainly used for air heating specifications in the air duct. It is divided into three forms: low temperature, medium temperature and high temperature. The common thing is that the steel plate supports the electric heating tube to reduce the vibration of the electric heating tube, and the junction box is equipped with an over temperature control device. On the other hand except in control with over temperature protection, between the fan and the heater is still transport device, to ensure that the electric heater must start after the fan is started in a heater plus differential pressure device, to prevent machine fault, gas pressure passage heater generally should not exceed 0.3Kg/cm2, if you need more than pressure. Please use the circulation type electric heater; low temperature heater type gas heating temperature is less than 160 DEG C; medium temperature is less than 260 DEG C; high temperature does not exceed 500 degrees. The air channel type electric heater is used for the industrial air duct, the air conditioning duct and the industry air to increase the temperature of the output air through heating the air, and is generally inserted into the transverse opening of the air duct. According to the working temperature of the wind tunnel, it is divided into low temperature, moderate and moderate temperature, and the wind speed, the middle wind speed and the high wind speed are divided according to the wind speed in the air duct.
