Problems solved by technology

Generally used as hydraulic oil for jacks, it is required to have excellent corrosion resistance, oxidation resistance and sealing applicability. Sometimes, jacks need to be used in cold areas, especially in winter, the temperature in some areas of our country will reach minus 20 ℃ , At this time, ordinary jack hydraulic oil cannot work normally at all, so there is an urgent need for a jack hydraulic oil that can work normally in an ultra-low temperature environment

Abstract

The invention discloses jack oil used at an ultralow temperature. The jack oil is prepared from the following components in parts by weight: 99 parts of hydrogenated tail oil, 0.1-0.3 part of an antirust agent, 0.2-0.4 part of an antioxidant, and 0.5-0.7 part of a functional agent, wherein the functional agent is prepared from the following components in parts by weight: 60-70 parts of 1-adamantanol, 10-12 parts of 3-nonanol, and 6-8 parts of tetra-n-butyl titanate. The jack hydraulic oil prepared by the method provided by the invention can work normally in an ultralow-temperature environment, and greatly improves the performance and the application range of a jack.

Description

technical field [0001] The invention belongs to the field of jack oil manufacture, and in particular relates to jack oil used at ultra-low temperature. Background technique [0002] The jack is the simplest lifting equipment with a lifting height of less than 1m. It uses a rigid top lifting piece as a working device, and is a light and small lifting equipment that lifts heavy objects in the stroke through the top bracket or bottom claw. Divided into two kinds of mechanical type and hydraulic type, the jack is mainly used in factories, mines, transportation and other departments as vehicle repair and other lifting, support and other work. Its structure is light and strong, flexible and reliable, and can be carried and operated by one person. As a tool with a wide range of uses, the jack is cast with the highest quality materials to ensure the quality and service life of the jack. Among them, the quality of the hydraulic oil in the jack directly determines whether the jack c...
