| Bearing heater frequency induction technology comes from the transformer of an accident short-circuit accident, in a moment to generate a strong current to release a huge heat of its principle of heat transfer efficiency to remove itself close to 100% loss, so the equivalent of a small transformer Bearing the heater is very high requirements for its manufacturing materials, the impact of its loss of production materials are mainly core materials and wound materials in two parts: Cixi 6300 bearing steel core material is silicon steel sheet in the silicon can reduce the Its own conductive properties, increase the resistivity of the eddy current to reduce its loss so the quality of the heater and the quality of silicon steel sheet has a great relationship. The quality of silicon steel sheet we usually use magnetic flux density to represent. Commonly used in the manufacture of iron core heater material is black iron sheet its magnetic flux density is 6000-8000, low silicon flux density is 9000-11000, high silicon flux density of 12,000 or more. The quality of silicon steel and silicon steel sheet orientation is also a considerable relationship between the example: Changzhou Yulong YJ30 series of mechanical and electrical bearing heater is used in Japan imported non-oriented silicon steel sheet compared with ordinary silicon steel core minus the Magnetic circuit and the silicon steel plate to the inconsistency of the increase in energy loss, if the use of non-oriented silicon steel production of the bearing heater energy consumption increased by at least 10% -15% or more. The material is usually made of copper wire, and its loss from the copper loss to that for a considerable small transformer and transformer bearing copper loss is greater than the iron loss so the material on the copper wire and the material process requirements are high It is best to use high-strength polyester enameled wire, which resistance is relatively small, good conductivity, the insulating paint layer has sufficient heat resistance, so with high-strength polyester enameled wire winding system heater performance is superior. |
