Problems solved by technology

Usually, the hydraulic support will be used in the extremely harsh environment of the underground, the environment is dirty, the traditional emulsified oil smells bad and the oxidation caused by factors such as solid impurities and miscellaneous oil pollution and bacterial reproduction during use, Make the emulsified oil easy to deteriorate and degrade, affect its freeze-thaw properties, anti-wear and extreme pressure resistance, anti-rust and anti-corrosion properties, and reduce the service life of the hydraulic system
The specific manifestations are: in the process of use, there will be turbidity, and there will be dirt such as oil and soap. This not only makes it difficult to keep the equipment system clean and clean, but also increases the number of disassembly and assembly of filters and valves in the system. The normal operation of the system is affected; during use, the hydraulic support will move slowly, which will affect the efficiency and safety of the operation

Abstract

The invention discloses antibacterial emulsified oil used for a hydraulic support. The emulsified oil is prepared from, according to certain ratio, sodium nitrite, triethanolamine, an emulsifier, basic oil, naphthenic acid, Turkey red oil, sodium hydroxide, EDTA, benzotriazole, a perfume essence, modified nano zinc oxide, ethylene glycol and water. In the emulsified oil, the modified nano zinc oxide is added and is matched with other dispersing agents in certain ratio, so that the emulsified oil has excellent dispersion performance of nano particles, and also has excellent antibacterial property, corrosion resistance, anti-rust property, wear resistance and extreme pressure resistance, and effectively avoids quality reduction caused by change on oil quality due to bacteria reproduction in a dirty and disorder environment. The emulsified oil is added with the perfume essence, which has good compatibility with other components and effectively improves the smell of the emulsified oil, thus providing a healthier working environment for miners.

Description

technical field [0001] The invention relates to an emulsified oil, in particular to an emulsified oil for an antibacterial hydraulic support. Background technique [0002] The hydraulic support is a mechanical equipment installed in the coal mining face. It is one of the key equipment in the fully mechanized mining face. It consists of columns, oil cylinders, top beams, bases, various control valves and pipelines. Its support, Lifting, moving, pushing and overload protection all rely on the emulsion to flow in a system composed of pipelines and control elements of a certain structure to achieve energy transmission and conversion, so the emulsion prepared with emulsified oil is called hydraulic support The "blood" of the system, there is no doubt that the quality of the emulsified oil is the key to the normal operation of the equipment. Usually, the hydraulic support will be used in the extremely harsh environment of the underground, the environment is dirty, the traditional...
