As high-value industrial equipment, daily maintenance directly affects its service life and weighing accuracy. Many enterprises neglect maintenance, resulting in scale deformation and sensor failure in 3-5 years, while well-maintained equipment can be used stably for 8-10 years. Xuzhou Speyer summarizes 5 key points for routine maintenance to help companies extend the life of their equipment.
1. Regularly clean the perimeter of the scale body to avoid debris jamming
The gap between the scale body and the foundation pit and the sensor installation position are easy to accumulate sand, soil and other debris, and long-term non-cleaning will lead to uneven force on the scale, bias load error, and even damage to the sensor. It is recommended to clean the area around the scale body once a week, and inspect it in time after bad weather such as heavy rain and strong winds to ensure that the scale body is free of debris jamming.
2. Do a good job of moisture-proof and waterproof sensors, and check the junction box regularly
Sensors and junction boxes are the core components of the weighbridge and are mostly IP67 rated, but long-term immersion or sealant aging can still cause water ingress failure. Before the rainy season, check the sealing of the junction box and replace the aging sealant; In a high humidity environment, moisture-proof desiccant can be added, and the sensor value is abnormal, and the power is cut off in time to avoid the expansion of the fault.
3. Regular calibration to ensure the accuracy of weighing
Weighbridges need to be professionally calibrated once every 6 months to 1 year, especially for weighbridges used for trade settlement, which must pass the annual inspection of the measurement department. If the data deviation is found to exceed the allowable range, it is necessary to contact the manufacturer in time to calibrate to avoid trade disputes caused by data errors.
4. Do a good job in anti-corrosion and anti-rust of the scale body, and adapt to the harsh environment
Outdoor weighbridges have been eroded by rain, salt spray and dust for a long time, and are prone to rust and corrosion. The scale body can be sprayed with anti-corrosion coating once a year, and in high salt spray scenarios such as ports, stainless steel sensors and junction boxes can be selected to extend the anti-corrosion life of the equipment.
5. Regularly check the circuit and power supply to ensure stable operation
peripheral circuits such as barriers and cameras of unattended weighbridges need to be checked regularly to avoid line aging and short circuits; In remote scenarios where there is no stable mains power, it is necessary to regularly maintain backup power to ensure that the equipment can save data normally when the power is cut off without affecting the weighing process.
Doing a good job in the above 5 points of maintenance can not only extend the life of the weighbridge, but also ensure the long-term accuracy of weighing data and reduce the maintenance cost in the later stage.
