What are the functions of the various lubricants and greases listed below, and where are they used? 1. Industrial-grade Delix S2M 68 hydraulic oil 2. Industrial-grade Delix S2M 46 3. Industrial-grade Kneader S4GX 220 synthetic gear lubricant 4. Industrial-grade Kneader S2G 460 mineral gear oil 5. Industrial-grade Kneader S2G 220 mineral gear oil 6. Industrial-grade Kneader S2G 150 7. Kneader S2G 320 mineral gear oil 8. VG32 (turbine oil) 9. Food oil 5L/Bottle – edible oil 10. Industrial-grade EP-2 lithium-based grease 11. Lithium molybdenum disulfide lithium-based grease No. 2
Could we consider this issue from a different perspective, by looking for the appropriate oil type based on the requirements of the equipment? For reference.
The original documents for the equipment are lost. How can one determine the condition of the equipment with regard to bearing lubrication for the centrifugal pump, as well as the gear meshing in the reducer and gearbox?
Losing it cannot be a reason for problems. Contact the manufacturer promptly for remedial action, or consult the Machinery Manual to check for any relevant requirements. It is similar to a hydraulic coupling, where there are specific requirements regarding the alignment of the couplings. Because hydraulic couplings generate high temperatures when operating under heavy loads, it is required that the alignment at normal temperature be below the center line. There is also the heat generated by the equipment during normal operation, which causes changes in the length of the spindle structure. Therefore, parameters for installation clearance are required for reference.
Rolling bearings are lubricated half with turbine oil or anti-wear hydraulic oil, while gearboxes use gear oil or lithium-based esters of type 2 or 3. In most cases, molybdenum disulfide grease can be used for rolling bearings; however, this substance should generally not be used, as it is only necessary in very high-temperature situations
What do you do for work? If you work in a technical field, then this is far too basic for you; it’s recommended that you avoid doing it
I’m sorry if this dampened your enthusiasm. You can start with the simplest things – for example, what kind of oil should be used in the pumps and bearings, and what oil is needed for the bearing housings. Work on these issues one by one. It’s like looking up information in a dictionary; this knowledge needs to be acquired gradually through experience. The key is to take into account the operating conditions and technical requirements, rather than just having theoretical knowledge.
The first 7 are from SHELL; the 8th power plant uses Kunlun more often, while the 9th can use Luhua: lol. EP2 generally refers to SHELL MOBIL 2, an extreme-pressure lithium-based lubricant, and the last one uses Great Wall: lol
The first one of ours is added to the plunger section of the Lewa diaphragm pump; the rest are various gearboxes and reducers. Just check according to the ISO or DIN standards
