For positive lubrication, helical, herringbone, bevel and worm. Divided into the following: ① enclosed gear oil. Conventional gear oils for light load operation of the gear lubrication; extreme pressure gear oil containing more extreme pressure antiwear agent for, heavy load or impact load of gear lubrication, and more for the metallurgical industry, and generally follow the American Gear manufacturers Association and the American Iron and Steel Company's specifications. ② open gear oil. High viscosity, strong adhesion. Heavy oil and asphalt or adhesive polymer modulation, easy to use plus diluent. ③ worm oil. Refined petroleum oil or synthetic oil plus the amount of fat or oily agent tune into.
Gear oil deterioration phenomenon
An appearance change color becomes deeper change mixed with
the abrasive. Mechanical impurities and oil mixed.
Viscosity changes with the oil of the viscosity index improver agent due to mechanical shear viscosity caused by the decline in oil oxidation and emulsification sludge resulting in viscosity increase
3, the change of acid value in the oil containing additives of high acid value, use the initial acid value decline in the consumption of additives in the table, post-acid value rise is the result of acidic oxidation products.
4, the moisture increases demulsibility worse. The extreme pressure agent hydrolysis lubrication and possible tooth surface pitting and glue.
5, benzene, pentane insolubles (petroleum ether) increase is the result of the oil in the long-term use at high temperatures, oxidation products and metal shavings, dust and other pollution.
One solution method recommended by my friend.
TYA vacuum Oil Purifier,TYA vacuum gear oil purifier which uses a vacuum heating works deal directly with the gear oil in the course of their work to produce the abrasive, water, gas, cleanliness can be achieved NAS6 level and above the new oil filter can be used directly, will not destroy the nature of the oil. It is a small investment, high economic value, but also energy saving and environmental protection, now has the majority of customers trust, recognition.
