Use range and operation mode of air duct heater

China's explosion-proof electrical industry a few years ago the overall economic growth has slowed in recent years, but the air electric heater of various economic indicators still maintain a rapid growth, economic development and economic benefits have been obtained in recent years is also good. With the development of coal industry, mine explosion-proof electrical apparatus has entered a period of steady and rapid development. While the rapid development of the industry, there are several major problems: the products circulation is more chaotic, product quality problems of some small enterprises outstanding, dumping phenomenon, disrupt the normal market order, at the same time to the safe production of users buried the hidden trouble, not conducive to enterprise development and industry technology progress explosion-proof electric appliance the industry concentration is too low, too many production enterprises, and most enterprises are small in scale, low tech products of the enterprise management level is not high, the low level of technology, product updates speed.

In addition, poor ventilation environment, also need the motor with forced air cooling function to ensure the normal cooling of the motor, it is worth mentioning here is the Italy CEMP small power explosion-proof electrical advantages in forced air cooling design, the motor has been widely applied in Maoming petrochemical, Guangzhou stone, Yunnan sky, Luoyang petrochemical and other domestic many large electrical machinery enterprises, the domestic brands in other large petrochemical projects are widely used. Like this kind of explosion-proof electrical apparatus which has strict requirements for motor volume and has special functions, there is a big gap between domestic explosion-proof electrical appliances manufacturers and foreign brands, and they must also rely on imported brands.

However, due to the complexity of the production and processing of power machinery, there will be special requirements for the technical parameters of the motor on some occasions. This kind of special requirements of explosion-proof electrical appliances at home can not be produced, even in the world only a few manufacturers can produce, must rely on imported brands, because of the outstanding advantages in high power and ultra high voltage explosion-proof electrical appliances, finally won the favor of the owner. In the production process of electric machinery, sometimes, due to the limitation of space environment, motors should not only have a relatively high explosion-proof level and protection level, but also have compact design and space saving design requirements. Explosion-proof electrical appliances can be applied to oil, natural gas, power machinery and chemical industry. In addition, it is also widely applied in mining, textile, metallurgy, city gas, transportation, grain and oil processing, papermaking, medicine and other industries. Therefore, grasping the market of electric heater of air channel is an indispensable part to enhance the brand construction of domestic industry.

Technological innovation is an important indicator to measure whether an enterprise has the advanced nature, whether it has the market competitiveness, and whether it can continue to lead the competitor. With the rapid development of the mineral electrical appliance market in China, the application and research and development of the core production technology will become the focus of the enterprises in the industry. To understand the R & D trend, process and equipment, technology application and trend of the core technology of mining electrical appliances at home and abroad is very critical for enterprises to improve product specifications and enhance market competitiveness.

The air duct heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850 degrees centigrade. It has been widely used in many research and production laboratories, such as aeronautics and Astronautics, weapons industry, chemical industry and colleges and universities. It is especially suitable for automatic temperature control and high flow high temperature combined system and accessories test. The range of air electric heater is wide: it can heat any gas and generate hot air, no water, no electricity, no burning, no explosion, no chemical corrosion, no pollution, safe and reliable, and the heating space will be heated up quickly (controllable).

Technical features of air duct electric heater

It can heat the air to a high temperature, up to 450 degrees centigrade, and the temperature of the shell is only about 50 degrees C.

High efficiency: up to 0.9.

The heating and cooling rate blocks can reach 10 /S, and the adjustment is fast and stable. The temperature control drifting will not appear and it is suitable for automatic control.

Good mechanical properties: because the heating body is special alloy material, so in the high pressure air flow under the impact of it than any body of the mechanical properties and strength are good, it takes a long time for the continuous of the air heating system and accessories test has more advantages.

When it is not in violation of the rules of use, it is durable and has a life span of several decades.

The air is clean, the volume is small and the people are good.

The air channel electric heater is designed beautifully and simply, and the plate is supported by the electric heating tube to reduce the vibration of the electric heating pipe. The over temperature control device is installed in the junction box of the electric heater of the wind channel. 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.
