The cleaning agent for the electrohydraulic control system of the fully-mechanized mining hydraulic support comprises the following components in parts by weight: 20 to 30 parts of organic acid, 20 to 30 parts of inorganic acid, 6 to 8 parts of metal corrosion inhibitor, 3 to 4 parts of surface active agent, 2 to 10 parts of ammonium salt, 2 to 10 parts of chelating agent, 10 to 20 parts of cleaning assistant, 1 to 5 parts of anti-wear agent, 1 to 5 parts of diethanol amine or triethanolamine, 15 to 18 parts of carbon deposition deliquescent substance, and 50 to 60 parts of water. The cleaning agent is mainly applied to the electrohydraulic control system of the fully-mechanized mining hydraulic support, and is capable of effectively clean various scourings on the electrohydraulic control system, and is good in cleaning effect, and energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the cleaning of coal mine mechanical hydraulic supports or the hydraulic system of fully mechanized mining hydraulic supports in coal mines, in particular to a cleaning agent for the electro-hydraulic control system of fully mechanized mining hydraulic supports and a preparation method thereof. Background technique [0002] The hydraulic support is one of the main equipments for fully mechanized coal mining production. The movement of the support is to use the pressure liquid to flow in a system composed of pipelines and control elements with a certain structure, so as to realize the transmission and conversion of energy. This pressure liquid Commonly known as the transmission medium, and the hydraulic transmission medium is an important part of the hydraulic system. Most of the transmission medium for coal mine hydraulic support is emulsified oil or emulsion for hydraulic support, and the cleanliness of the emulsified oil is t...
