Effective maintenance of LPG Cylinder Longitudinal Welding Machine requires key component maintenance, system performance testing, and preventive maintenance. As a core component, the welding power supply should be cleaned of internal dust every month, and the heat sink should be blown with compressed air (pressure 0.4-0.6MPa) to prevent dust accumulation from overheating the IGBT module. The output voltage and current stability should be tested every six months, and calibration is required if the deviation exceeds ±5%. The wire guide tube and wire feeding wheel of the wire feeding mechanism should be checked for wear every 200 hours. If the scratch depth of the inner wall of the wire guide tube is greater than 0.3mm or the V-groove of the wire feeding wheel is worn and causes the welding wire to slip, it needs to be replaced in time; apply molybdenum disulfide grease regularly (once every 100 hours of operation) to reduce transmission resistance.
Among the mechanical moving parts, the linear guides and screws need to be checked for lubrication status every week, and lithium-based grease (NLGI Grade 2) needs to be added to prevent dry friction; the parallelism and straightness of the guide rails need to be checked, and recalibration is required when the error exceeds 0.1mm/m. The gas system tests the sealing of the protective gas pipeline every quarter, smears the joints with soapy water, and replaces the seals when bubbles appear; the gas flow meter and pressure reducing valve are calibrated monthly to ensure that the flow fluctuation is ≤±2%.
In addition, equipment operation files are established to record the replacement time of key components and fault repair conditions, and preventive maintenance plans are set based on the equipment operation hours. Vibration sensors (monitoring motors and transmission components) and temperature sensors (monitoring power modules) are used for status monitoring, and abnormal data is promptly warned, which can effectively reduce the probability of sudden failures and extend the service life of equipment.
