Publish Time: 2025-02-12
As a key technology to improve the efficiency of solar power generation, photovoltaic tracking system has lead screw motor as one of its core components. Lead screw motor enables photovoltaic panels to accurately track the position of the sun and maximize the light receiving area through precise transmission control. However, photovoltaic tracking systems are usually installed outdoors and exposed to various harsh climatic conditions for a long time, so the weather resistance of lead screw motor is particularly important.
Weather resistance evaluation mainly focuses on the operating stability and life of lead screw motor in extreme temperature, humidity, ultraviolet radiation and other environments. First, through experimental simulation of extreme climatic conditions, such as high temperature and low temperature cycle tests, the thermal expansion coefficient, lubrication effect and electrical performance stability of lead screw motor can be evaluated. Secondly, humidity test can test the sealing performance and corrosion resistance of lead screw motor in humid environment. Finally, long-term ultraviolet radiation test can evaluate the degree of material aging and the impact on motor performance.
In order to improve the weather resistance of the lead screw motor, the following aspects can be taken into consideration:
Material selection: Select materials that are resistant to high temperature, corrosion, and UV radiation, such as special alloys, polymer composite materials, etc., to improve the overall weather resistance of the lead screw motor.
Sealing design: Optimize the sealing structure of the lead screw motor to prevent moisture and dust from entering the motor, thereby extending its service life.
Lubrication system: Use long-lasting, high-temperature-resistant, and anti-aging lubricants to ensure that the lead screw can maintain good lubrication at different temperatures.
Coating protection: Apply anti-corrosion coatings on the surface of the lead screw and motor housing to improve corrosion resistance.
Intelligent monitoring: Integrate temperature sensors, humidity sensors, etc. to monitor the working environment of the motor in real time, and take immediate measures once abnormalities are found to avoid failures.
In addition, regular maintenance and inspection are also key to ensuring the weather resistance of the lead screw motor. By regularly replacing lubricants, cleaning dust, and checking seals, problems can be discovered and solved in a timely manner to ensure the stable operation of the photovoltaic tracking system.
In summary, the evaluation and improvement of the weather resistance performance of the lead screw motor in the photovoltaic tracking system is a systematic project, which requires comprehensive consideration from multiple aspects such as material selection, design optimization, lubrication system, coating protection and intelligent monitoring to ensure that the lead screw motor can operate stably under various harsh weather conditions, thereby improving the overall performance and power generation efficiency of the photovoltaic tracking system.
