In order to make the washing machine run normally and easy to use for a long time, it is necessary to carry out correct lubrication and maintenance on time. The places that need lubrication are mainly the bearings and gears. The bearings need to be injected into the oil hole with good anti-wear and anti-oxidation stability. Rust anti-oxidation lubricating oil is generally refueled once every 2-3 years, if general machine oil is used, it needs to be refueled once a year. For gears, use No. 2 extreme pressure lithium grease with good adhesion, or with good oiliness, plus 1% zinc dialkyl dithiophosphate, or 3% MoS2, L-CKC100 No. medium extreme pressure anti-wear gear oil for lubrication. The bearings and gears of the spin dryer should be added with L-AN15 and L-AN68 lubricants with good anti-oxidation, rust and anti-wear properties every year or half a year. For sealed rolling bearings, the bearing factory should be sealed with polyurea-based thickened refined petroleum lubricating oil with a service life of more than 1,000 hours, and added with anti-rust and antioxidant No. 2 grease.
