Wind power industry thermal disassembly how to use induction heater to improve efficiency
The Definition of Thermal Dismantling and its Role in the Wind Power Industry
·Thermal disassembly refers to the process of installing or disassembling parts after they reach a certain temperature by heating. In the wind power industry, it is mainly used for the assembly and maintenance of large bearings, gears and other key components.
·Function: It can reduce the difficulty of assembly, improve the assembly precision, reduce the damage to the parts, and prolong the life of the parts.
The key technical points of thermal disassembly
·Temperature control: the heating temperature should be precisely controlled to ensure that the parts reach the expansion degree of the road, so as to facilitate the installation or disassembly. Different parts of the heating temperature varies greatly, such as bearings, hot disassembly temperature is generally between 80 ℃ - 120 ℃.
·Heating uniformity: to ensure that the parts of the overall uniform heat, to avoid local overheating or overcooling leading to deformation or damage. Commonly used heating methods are induction heating, flame heating, etc., of which the uniformity of induction heating is better.
·Dismantling tools and equipment: professional dismantling tools and equipment, such as heaters, temperature sensors, pullers, etc., to ensure the smooth progress of the thermal dismantling process.
1.Optimization of heating process
When using electric touch heating equipment, according to the specifications and materials of different parts, the best heating procedure can be set up in advance, for example, for common wind power bearings, by accurately setting the heating temperature curve, at the initial stage of the lower power preheating, so that it is uniformly warmed up, and then gradually increase the power to the appropriate heating rate to ensure that the installation of the shortest possible time to achieve the required temperature range, generally 80 ℃ to 120 ℃ or so, so as to reduce the thermal stress caused by rapid changes in temperature, improve the installation efficiency while ensuring the quality of parts.
Utilizing the fast response characteristics of electromagnetic heating equipment, combined with the real-time feedback temperature data from the sensor, to achieve precise temperature control. Once the preset temperature is reached, the heating will be stopped immediately to avoid wasting time and energy by excessive heating.
2.Adaptation to different components
Customize special electromagnetic heating tooling for various large parts in the wind power industry, such as gears and hubs. These fixtures should be able to work perfectly with the electromagnetic heating equipment to ensure that the electromagnetic energy is efficiently transferred to the components to achieve uniform heating, for example, for irregularly shaped gears, special shaped heating coils can be designed to closely fit the surface of the gears to improve the heating efficiency.
According to the size and weight of the components, select the appropriate power of the electromagnetic heating equipment. For the thermal dismantling of large wind tower connecting bolts, high power electromagnetic heating equipment is required to ensure that the bolts are heated to the required temperature within a reasonable time for easy dismantling and installation.
3. Improve equipment reliability
Selection of reliable quality and stable performance of electromagnetic heating equipment to reduce equipment failure and maintenance time. Some advanced electromagnetic heating equipment with self-diagnosis and protection functions, such as overcurrent protection, overheating protection, etc., when the equipment can automatically stop working when anomalies occur, to avoid damage to the components and the equipment itself, regular maintenance and repair of the electromagnetic heating equipment, clean the heating coil, check whether the electrical connection is good, to ensure that the equipment is always in the best working condition For example, quarterly on the equipment for a Comprehensive inspection and calibration of the equipment quarterly to ensure the accuracy of temperature control.
4.Personnel training and operation standardization
Provide professional training to the operators to make them familiar with the operation methods and precautions of the electric touch heating equipment. Operators should understand the heating requirements and best practices of different components and be able to flexibly adjust the heating parameters according to the actual situation. For example, train operators how to properly adjust heating:time and power according to changes in ambient temperature and humidity.
Establish strict operating specifications and safety protocols to ensure a safe and efficient thermal disassembly process. Operators must operate in strict accordance with the specifications, such as in the heating process to maintain an appropriate safety distance, to avoid the electric touch radiation on the human body caused by injury; in the dismantling and installation of components, the use of correct tools and methods to prevent accidents.
