Proper installation and maintenance of screws in solar energy equipment are crucial for ensuring the stability, safety, and efficient operation of the equipment. Here is a detailed introduction:
Installation Steps and Key Points
Preparation Work: Before installation, carefully check whether the specifications and model of the screws match the installation requirements, and inspect the screw surface for damage, rust, or other issues. Meanwhile, prepare appropriate installation tools such as wrenches and screwdrivers.
Determine Installation Position: According to the installation drawings of the solar energy equipment, accurately determine the installation positions of the screws. Ensure the accuracy of the installation positions to avoid situations where screws cannot be installed properly or the overall structure of the equipment is affected due to positional deviations.
Pre-installation and Adjustment: Gently screw the screws into the mounting holes without fully tightening them, to facilitate fine-tuning of the equipment's position and angle. When installing solar photovoltaic panels, adjust the tightness of the screws to ensure the surface of the photovoltaic panels is flat, thereby achieving the best lighting effect.
Tightening Screws: Use appropriate tools to tighten the screws according to the specified torque value. Different specifications and materials of screws have different tightening torque requirements. Generally, the tightening torque for stainless steel screws should be moderate; over-tightening may cause damage to the screws or connected components, while under-tightening will affect the firmness of the connection. A torque wrench can be used to ensure the tightening torque meets the requirements.
Anti-loosening Treatment: To prevent screws from loosening due to vibration or other reasons during equipment operation, corresponding anti-loosening measures can be taken, such as installing lock washers or using thread lockers. For some important connection parts, the double nut anti-loosening method can be adopted.
Maintenance Methods and Key Points
Regular Inspection: Establish a regular inspection system to conduct a comprehensive inspection of the screws of solar energy equipment at regular intervals (such as quarterly or semi-annually). Check whether the screws are loose, rusted, broken, or have other problems. For equipment installed in harsh environments (such as coastal areas or high-wind sandy areas), the inspection frequency should be appropriately increased.
Tightening Loose Screws: After ，promptly use appropriate tools to tighten them. When tightening screws, be careful to avoid over-tightening to prevent damage to the screws or connected components. If the screws are severely loose, it may be necessary to check for other potential problems, such as deformation of equipment components, and handle them in a timely manner.
Handling Rusty Screws: For slightly rusted screws, use sandpaper or a wire brush to clean off the rust, then apply anti-rust grease to prevent further rusting. If the screws are severely rusted and their performance cannot be restored through simple treatment, they should be replaced with new ones in a timely manner.
Replacing Damaged Screws: When screws are found to be damaged, such as broken or severely deformed, they must be replaced with new ones immediately. When replacing screws, select products with the same specifications, model, and material as the original screws to ensure the reliability of the connection.
Recording Maintenance Conditions: Keep detailed records of each maintenance activity, including inspection time, problems found, and treatment measures. By recording maintenance conditions, the operating status of equipment screws can be understood in a timely manner, providing a reference for subsequent maintenance and management.
