Emulsified oil for hydraulic bracket and production technology of emulsified oil

Abstract

The invention discloses emulsified oil for a hydraulic bracket and a production technology of the emulsified oil. The emulsified oil for the hydraulic bracket is prepared from the following substances: mineral base oil, oleic acid, triethanolamine, petroleum sodium sulfonate, benzotriazole, glycerin, S-80, Op-10, urea, EDTA, sodium hydroxide and the balance of water. The emulsified oil is stable in performance, good in emulsifying effect, free of separation of dirts, such as oil and soap and longer in service time, has good freeze-thaw stability, anti-wear and anti-extreme pressure properties and anti-rust and anti-corrosive properties and can meet the requirements of use of the hydraulic bracket under a harsh work condition, a long-term use system is clean, the whole system normally runs, the hydraulic bracket does not have the phenomenon of slow action, operation is safe and accurate and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of emulsified oil, in particular to an emulsified oil for hydraulic supports and a production process thereof. Background technique [0002] Hydraulic support is a kind of hydraulic power device that uses liquid pressure to generate support force and realizes automatic shifting for roof support and management. It is an indispensable supporting equipment for comprehensive mechanized coal mining. The hydraulic support is mainly used in the longwall fully mechanized mining face of the horizontal plane and the gently inclined thick coal seam of less than or equal to 10 degrees and the full-height mining of the top coal mining along the floor, and is also suitable for the horizontal layered top coal caving work of the steeply inclined ultra-thick coal seam noodle. Mining face mine pressure acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraul...

Problems solved by technology

Static electricity may also cause local instantaneous high temperature of the oil, which will cause oil deterioration and damage important components in the system, such as servo valves and proportional valves

Static electricity can also produce a very small (size <1um) yellow or brown viscous colloidal substance in the emulsified oil - sludge glue, which will be adsorbed on the inner wall of the system pipes, hydraulic components or high-precision control valves On the valve core and valve sleeve, a very thin sludge layer is formed, causing the system to malfunction

[0005] It can be seen that the electrostatic phenomenon has become a serious threat to the normal operation of the hydraulic system, causing great economic losses to users, and an urgent problem to be solved.
