Let’s discuss equipment lubricants

In any case, the following principles should be followed: the \"five fixed principles\" for equipment lubrication and the \"three filtrations\" are effective methods for standardizing and institutionalizing daily lubrication management tasks, ensuring proper lubrication practices; they also represent the experience accumulated in lubrication work in our country. Enterprises should organize these efforts carefully and carry them out effectively. 1. Contents of the “five fixed principles” for lubrication management: (1) Fixed location – Perform oil filling, top-up, and oil replacement at the locations, lubrication points, and inspection points (oil level sight glasses) specified in the lubrication chart, and check the oil level and supply condition. (2) Qualitative determination: Identify the type, grade, and quality requirements of the oil required for the lubrication areas; the oil to be used must pass testing. The use of alternative materials or their incorporation requires a scientific basis. The lubrication devices and tools must be thoroughly cleaned to prevent contamination of the oil. (3) Quantification: Perform regular lubrication of the lubricated parts in accordance with the specified quantities, implement quota management for oil consumption, and ensure proper addition of oil, refilling of oil, as well as cleaning and changing of oil tanks. (4) Regularly refill oil at the intervals specified on the lubrication card, and conduct sampling tests at the prescribed intervals. Based on the results, decide whether to clean and change the oil or to use circulation filtration, as well as determine the timing for the next sampling test. This is an important aspect of proper lubrication maintenance. (5) Assignment of tasks: In accordance with the specifications in the chart, the operator, maintenance worker, and lubrication worker are responsible for filling oil, adding oil, cleaning, and changing oil, respectively; meanwhile, a designated person is assigned to take samples for testing. The equipment department should prepare a standard table for the \"five fixed principles\" of lubrication management, specifying which equipment and which parts require lubrication, what type of oil to use, the frequency of oil filling (or oil change), what lubrication equipment to employ, and who is responsible for these tasks. With the advancement of science and technology and the accumulation of experience, “fixed-point management” needs to be further enhanced and improved in practice. 2. “Three filtrations” – Also known as three-stage filtration, this approach is taken to reduce the amount of impurities in the oil and to prevent dust and other contaminants from entering equipment along with the oil. It includes filtration upon receipt, filtration before distribution, and filtration during refueling. Its meaning is as follows: (1) Inlet filtration – The oil must be filtered when it is transported in and pumped into the oil tank for storage. (2) Filtration during dispensing: Oil should be filtered before being poured into the lubrication container. (3) Fuel filtration: The oil must be filtered before being added to the equipment’s oil storage area.

In our factory, 46# and 68# anti-wear hydraulic oil are the most commonly used; it seems that ordinary pumps use this type of oil. Next is refrigeration oil, which is also quite common I guess! :lol

This question is too broad; it would take days to discuss it in detail. What kind of device is it? Please tell us, what equipment does it have?

This is a quite broad topic. As I understand it, the greater the load on the equipment, the higher the temperature, and the higher the viscosity of the oil required ； For lubricants used in industry, the higher the grade number, the greater the viscosity.
