Fault Diagnosis
Observation and inquiry: The maintenance personnel first observe the appearance of the equipment to check for obvious damage, deformation or loose parts. At the same time, ask the operator about the situation before and after the failure, such as the sound of the equipment running, whether there is any abnormal smell, the operation process, etc., to preliminarily determine the general direction of the failure.
Detection of equipment parameters: Use professional detection tools, such as multimeters, oscilloscopes, etc., to detect the electrical parameters of the equipment, including voltage, current, resistance, etc., to determine whether the electrical system is normal. For the mechanical part, check the operation of the transmission parts, the degree of wear of the mold, etc.
Targeted Maintenance
Electrical fault maintenance: If the detection finds that the electrical components are damaged, such as contactors, relays, sensors, etc., it is necessary to replace the components of the same specifications in time. At the same time, check whether the electrical circuit is short-circuited or open-circuited, and repair or replace the damaged circuit.
Mechanical fault maintenance: For wear, looseness or damage of mechanical parts, such as chains, gears, bearings, etc., repair or replace. If there is a problem with the mold, which affects the quality of gutter forming, the mold needs to be polished, repaired or remade.
Debugging After Maintenance
No-load debugging: After the maintenance is completed, first perform no-load debugging, let the equipment run under no-load conditions, observe the operation of the equipment, check whether the operation of each component is normal, and whether there is abnormal vibration or noise.
Load debugging: After the no-load debugging is normal, perform load debugging, gradually increase the load of the equipment, produce a certain number of gutter products, check whether the product quality meets the requirements, and ensure that the equipment resumes normal production capacity.
