Lubricating oil for fully automatic pumping lubrication system equipment and preparation method thereof

Abstract

The invention discloses lubricating oil for a full-automatic pump lubrication system device and a preparation method of the lubricating oil. The lubricating oil is prepared from the following components in percentage by mass: 60-70% of high-viscosity base oil, 15-25% of low-temperature and low-viscosity base oil, 2-6% of 12-hydroxy stearic acid, 1-5% of a polyisobutene adhesive, 0.1-1% of a liquid polymeric phenol antioxidant, 1-3% of a first antiwear agent and 2-5% of a second antiwear agent, wherein the kinematic viscosity of the high-viscosity base oil at 40 DEG C is 200-350 centistokes and the pour point is -20 DEG C to-10 DEG C; the kinematic viscosity of the low-temperature and low-viscosity base oil at 40 DEG C is 1-10 centistokes and the pour point is -50 DEG C to -30 DEG C. After the lubricating oil formula is adopted, an ideal ram material function combination can be obtained; the prepared lubricating oil is good in adhesion property, good in flowability, good in extreme pressure property, high in abrasion resistance and long in service life, can be suitable for the full-automatic pump lubrication system device and can smoothly reach the required joint part through a fine oil supply pipe.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil for fully automatic pumping lubricating system equipment and a preparation method thereof. Background technique [0002] The joints in mechanical equipment are like the joints of the human body. They are the most fragile and need the most protection. They are also the places most prone to wear and failure. The wear of the joints directly affects the accuracy of the equipment and even causes the equipment to be scrapped in advance. At present, most of the joints of the equipment mainly use engine oil, hydraulic oil, grease or joint oil on the market for simple lubrication, but the oil or hydraulic oil has poor adhesion and is easy to drip. The small amount of oil absorbed by the arm will cause dry friction and wear the joint arm; the grease has poor fluidity and is mainly used for manual filling of gear bearing joints, but it is not suitable for automatic pumping l...

[0002] The joints in mechanical equipment are like the joints of the human body. They are the most fragile and need the most protection. They are also the most prone to wear and failure. The wear of the joints directly affects the accuracy of the equipment and even causes the equipment to be scrapped in advance.

At present, most of the joints of the equipment mainly use engine oil, hydraulic oil, grease or joint oil on the market for simple lubrication, but the oil or hydraulic oil has poor adhesion and is easy to drip. The small amount of oil absorbed by the arm will cause dry friction and wear the joint arm; the grease has poor fluidity and is mainly used for manual filling of gear bearing joints, but it is not suitable for automatic pumping lubrication systems; ordinary joint oil on the market has poor adhesion and is easy to drip Falling, poor extreme pressure performance and poor anti-friction effect

These cannot really achieve the effect of lubricating and protecting the joints of mechanical equipment
