This paper retrospects the history of conducting research into the antifreezing mechanism of mineral lubricating oil, points out the limitation of the traditional antifreezing mechanism on explaining the low-temperature flow of bio-degradable lubricating oil, and studies the low-tmperature flow mechanism of a bio-degradable lubricating oil by tests. 回顾了矿物润滑油降凝机理的发展历史,指出了传统降凝机理在解释生物可降解润滑油低温流变的局限性,并通过试验来研究生物可降解润滑油的低温流变机理。
In the light of the fact that the wastage of antifreezing machine oil in the casing-pressure device of the water injection well result in failure of pressure gauge, a set of high-pressure lubricator ( ZJT-1 type) was developed based on the theoretical calculation and field condition. 针对注水井防冻防盗套压装置里的防冻机油损耗而导致压力表冻坏的问题,在理论计算的基础上,结合现场实际,研制成功了一套ZTJ-I型高压加油器。
