Qingdao Hexin Machinery specializes in the production of fans for heat treatment multi-purpose furnaces, including carburizing furnace blades, tempering furnace impellers, nitriding furnace blades, vacuum furnace blades, etc. The main materials of multi-purpose furnace fans are 1.4849, 1.4857, 2.4879, 1.4865, etc. . It can be used for blank parts or machining, dynamic balance inspection to ensure product performance. Fans of different materials, specifications and models can be recommended and produced according to customer needs.
The fan of the multi-purpose furnace generally does not have speed regulation. Of course, the requirements of the buyer can be met. This is of little significance, because the size of the space in the furnace is certain, and it is always hoped that the atmosphere in the furnace will be uniform at the maximum speed (power frequency). Temperature uniformity achieves the best results.
The main functions of the multi-purpose furnace fan are: 1. To ensure uniform temperature in the furnace. 2. Ensure the uniformity of the atmosphere in the furnace.
For the multi-purpose furnaces produced by each manufacturer, because the furnace structure is different, the fan selection must be different. Aixelin, Ipsen, Huisen and other furnace types, because the furnace adopts a muffle structure, in order to ensure temperature uniformity And the uniformity of the atmosphere, it is necessary to choose a stirring fan with a large air pressure and air volume, so the motor speed and power are also high, generally 4.5kw, more than 1000 revolutions. The fan blades also need to be made of high-quality materials, and the dynamic balance is also very demanding. In order to meet the low temperature process, some manufacturers also use a two-speed motor to solve the problem of large air resistance and motor heating at low temperature. The furnace types such as Fengdong are circular furnaces without muffles and do not require high wind pressure. Therefore, the speed of the fan shaft is 740~760 rpm. The power is generally 2.2kw. The fan blade selection of this type of furnace is not as good as the previous one, and of course it is not necessary to use high speed and good materials.
