Basic tools include: fixed oil tanks, oil pumps, oil lifting tanks, oil pots, oil collection trays, filtering funnels, grease tanks, grease shovels, grease guns, etc. 4.3.2 All lubrication tools should be clearly labeled, used only for their designated oils, and cleaned regularly. Under normal circumstances, fixed oil drums (tanks) should be cleaned every 3 months ; The remaining items should be washed once a week. After using or cleaning each utensil. It should be placed neatly at the designated location. 4.3.3 The oil used for equipment lubrication should be managed under a “three-stage filtration” system, with the third stage of filtration particularly requiring strict implementation. The schematic diagram of the three-stage filtration is shown in Figure 1. file:///C:\Users\BlackFox\AppData\Local\Temp\ksohtml\wps2A72.tmp.jpg 4.3.4 The filters used in the three-stage filtration must meet the following requirements: 4.3.4.1 For filters used with hydraulic oil, turbine oil, refrigeration oil, compressor oil, motor oil, or other oils with similar viscosity: 60-mesh for the first stage ; Secondary grade, 80 mesh ; Grade 3, 100 mesh. 4.3.4.2 The number of filters for other oils with high viscosity should be reduced accordingly; in case of special requirements, the relevant special provisions shall apply. 4.4 Use of Lubricants 4.4.1 Equipment must be lubricated with oils that meet the specified requirements; arbitrary misuse or mixing of oils is not allowed, and substandard oils shall not be used. The selection of lubricating oil for equipment should take into account three factors: the grade of lubricating oil recommended in the equipment manual, the recommended lubricating oils for equipment listed in Appendix A, and any optimizations implemented under the unified management of the organization. 4.4.2 When a change in oil type is required, approval from the equipment management department must be obtained; the oil-using units shall not make any changes at will. 4,4.3 The substitution of lubricating oils must adhere to the principle of equal quality or using a superior alternative; substitution should cease once the specified oil is supplied. 4.4.4 When it is necessary to replace lubricants of different types, or when the existing lubricant fails inspection and needs to be replaced, the old lubricant should generally be completely removed first, before the new one is added. If online oil replacement is required due to certain constraints, a replacement plan must be developed and approved by the equipment management department before it can be carried out. 4.4.5 For equipment that is newly installed and put into operation for the first time (during the running-in period), it is generally necessary to change the oil once every 15 to 30 days ; Under normal operation, the oil change interval should be determined according to the five-fixed schedule or the lubricant inspection report. For equipment that operates intermittently or is not in use for extended periods, the quality of the lubricating oil should be checked regularly and replaced as needed. 4.4.6 The lubricating oil of key units in operation should be inspected at least once a month; under harsh conditions or towards the end of the operation period, the frequency of inspections as well as the checks related to the film index should be increased accordingly. Any deficiencies found should be addressed promptly, and it is recommended to use online oil purification devices that can remove water and oil films. The inspection report for the lubricating oil must be kept properly. 4.5 Equipment Lubrication and Oil/Fatty Fluid Application Standards 4.5.1 Oil lubrication: The amount of oil to be applied should be determined based on the scale markings.
