Abstract

The invention provides energy-saving environment-friendly water-based concentrated solution for a fully mechanized mining hydraulic support electrohydraulic control system under a coal mine, which is applied to different water qualities such as total hardness, sulfate radicals, chlorine radicals, bicarbonate radicals and the like through concentration ratio adjustments. The concentrated solution greatly improves lubricating property, rust resistance, corrosion resistance, sealability and cleaning and filtering characteristics of the fully mechanized mining hydraulic support electrohydraulic control system under the coal mine, has a function of repairing a metal frictional wear surface, prolongs the service life of equipment, changes a frictional interface, avoids pollutions, prevents original emulsified oil and microemulsion from polluting water resources of a mining area, and saves nonrenewable oil resources, so the concentrated solution is an energy-saving and environment-friendly substitute upgrading product, and simultaneously the concentrated solution meets national and international low-carbon economic development general requirements on energy saving and emission reduction,and has predominant economic benefits and social benefits.

Description

Technical field: [0001] The invention relates to an auxiliary agent for a lubricating transmission system of a coal mine mechanical hydraulic support, in particular to a concentrated liquid used in an electro-hydraulic control system of a fully mechanized hydraulic support. 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 for hydraulic support, and the emulsified oil is made of refined mineral oil as the main raw material, and then added with other additives. It consum...
