Background
The transmission oil of the transmission is used for forming a lubricating oil film on the friction surfaces of all moving parts of the transmission to lubricate, so that the friction resistance between the relative moving parts in the transmission is reduced, and the abrasion of parts is reduced. However, the gearbox oil itself contains a certain amount of colloid, impurities, moisture and additives, and meanwhile, during the working process of the gearbox, metal abrasive dust is carried in, impurities in the air enter the gearbox oil and oxides of the gearbox oil are generated, so that the impurities in the gearbox oil are gradually increased. If the gearbox oil is not filtered and directly enters the lubricating oil way, sundries contained in the gearbox oil can be brought into friction surfaces of moving parts, abrasion of parts is accelerated, and the service life of the gearbox is shortened. The oil absorption filter is used for filtering sundries in the gearbox oil and providing the sundries to the gearbox oil with clean gearbox oil.
The tightness of the oil absorption filter is an important index of the performance of the filter product. If the oil filter is not tightly sealed for some reason during production and is not detected at the time of factory inspection, then the oil filter is mounted on the gearbox to generate leakage, unfiltered gearbox oil can enter the engine, and the gearbox is worn.
At present, the tightness of the oil absorption filter is detected by manually pressing an oil inlet hole, directly inserting a plastic air pipe into the oil outlet hole, flushing gas, and observing whether bubbles exist in water.
