1 Clean your equipment regularly

One of the most essential tasks for maintaining your fabrication equipment is to clean it regularly. Cleaning removes dust, particles, residues, and contaminants that can damage your equipment or interfere with your processes. Depending on the type and frequency of use of your equipment, you may need to clean it daily, weekly, or monthly. You should follow the manufacturer's instructions and use the appropriate cleaning agents and tools for each component. For example, you may need to use ultrasonic cleaners, wet wipes, vacuum cleaners, or compressed air to clean different parts of your equipment.

Keeping industrial sensors clean and well-maintained is crucial for ensuring accurate and reliable data collection. 5 essential tips for cleaning industrial sensors. 1. Regular Inspection: Inspect your industrial sensors to identify signs of dirt, dust, or debris buildup. 2. Gentle Cleaning Solutions: When cleaning industrial sensors, it's essential to use gentle cleaning solutions that won't damage sensitive components. 3. Soft Brushes or Compressed Air: Utilize soft brushes with fine bristles or compressed air to remove loose particles from the sensor surface. Non-excessive force. 4. Automated Sensor Cleaning: Consider implementing. 5. Calibration Verification: After cleaning perform calibration verification tests.

2 Perform preventive maintenance

Preventive maintenance is the process of inspecting, servicing, and repairing your equipment before any major problems occur. Preventive maintenance can help you extend the lifespan of your equipment, reduce downtime, and save costs. You should follow a preventive maintenance schedule based on the manufacturer's recommendations and your own experience. You should also keep a log of all the preventive maintenance activities and results for future reference. Some of the preventive maintenance tasks you may need to perform include replacing worn-out parts, lubricating moving parts, checking electrical connections, and testing safety features.

Inspect electrical systems thoroughly every 3 to 5 years. Inspect individual assets according to the manufacturer's directions or based on experience and industrial training. Checking motors quarterly and air handlers only annually is an example. Preventive maintenance of electrical systems goes beyond the visual or scheduled predictive maintenance work. A full electrical PM is a complete look at the electrical system, including; * Re-torque connections. * Checking panel boards. * Inspecting PLCs for effectiveness. * Examining work orders as well as new installs for compliance and uniformity. * Make sure lock-out tags are in place. * Inspection of heating and cooling units. * Lighting. * GFCIs. * Shutdown mechanisms. NEC code compliance

3 Calibrate your equipment periodically

Calibration is the process of adjusting your equipment to ensure that it meets the specified standards and accuracy. Calibration is important for ensuring the quality and consistency of your products and processes. You should calibrate your equipment periodically according to the manufacturer's specifications and your own quality control requirements. You should also calibrate your equipment whenever you install, move, or modify it. You should use certified calibration tools and methods for each type of equipment. For example, you may need to use voltmeters, oscilloscopes, thermometers, or pressure gauges to calibrate different parameters of your equipment.

It is necessary to check and calibrate the high and low levels and the span when the Ultrasonic Level Detector (ULD) is in its final position. With tanks, this is done by filling them with water, physically dipping, measuring the levels, and comparing results. In situations where water cannot be used, it may be possible to dip the product or take the ULD to a ‘dummy’ test set-up on another item of equipment where water can be used and then replace it in its required position.

4 Monitor your equipment performance

Monitoring your equipment performance is the process of collecting and analyzing data on how your equipment operates and affects your processes and products. Monitoring your equipment performance can help you identify and troubleshoot any issues, optimize your settings, and improve your efficiency and productivity. You should monitor your equipment performance continuously or at regular intervals using the built-in sensors, indicators, and software of your equipment. You should also use external tools and methods to measure and verify your equipment performance. For example, you may need to use optical microscopes, scanning electron microscopes, or profilometers to inspect the surface and morphology of your products.

5 Train your staff properly

Training your staff properly is the process of ensuring that your staff have the necessary skills and knowledge to operate, maintain, and calibrate your equipment safely and effectively. Training your staff properly can help you prevent human errors, accidents, and injuries, as well as increase your staff morale and satisfaction. You should train your staff regularly using the manufacturer's manuals, online courses, videos, or workshops. You should also assess your staff's competence and performance and provide feedback and support. You should also encourage your staff to share their best practices and learn from each other.
