Review the separation of each part and check whether the main process components meet the process requirements. (4) Check whether the transmission components are in good condition and whether the fasteners are loose or displaced. (5) Check whether the safety devices, pneumatic devices, electrical devices, and electronic monitoring originals work well. 1.4 Main Points of Lubrication and Maintenance Lubrication and maintenance are the basis of equipment maintenance work. To ensure the product quality of oil and fat, the oil and grease entering the factory should be inspected and the quality meets the requirements of the equipment before use. The period of the key oiling parts of the combing card is shown in Table 1. Table 1 Periodic table of key refueling parts of combing carding port (1) When refueling and lubricating operation, the refueling cycle and refueling type should be strictly implemented to avoid missing oil eyes, poor oil passage or blockage It must be cleaned in time to ensure the smoothness of the oil passage. (2) The oil eye must be cleaned up when refueling. The rolling bearings of various transmission components (such as thugs, rollers, cylinders, doffers, motors, fans, etc.) must be cleaned of iron filings and dust Lubricating oil can be added after miscellaneous. (3) The amount of lubricating oil should be moderate. For example, the gearbox should pay close attention to the oil level line. The rolling bearing should be flexibly controlled according to the speed. It should be added without excessive overflow. Chains, sprockets, gears Wait less, and work harder. (4)Lubricating grease and 150D DTY YARN tools should be kept clean, free of dust and other impurities, and untreated recycled oil cannot be applied. (5) The abnormal noise and heat of the machine should be found during the refueling process. Stop and repair immediately. (6) During the refueling operation, strictly follow the safety operation procedures of this procedure and standardize the operation. The parts that need to be refueled should be more cautious, pay attention to safety, and avoid the occurrence of safety accidents. 1.5 The main points of electrical maintenance (1)
