Abstract

The invention relates to an environment-friendly concentrated solution for a hydraulic support. The environment-friendly concentrated solution comprises the following components in percentage by mass: 12%-25% of composite lubricant, 0.005%-0.015% of antifoam agent, 0.005%-0.02% of foam inhibitor, 1.0%-7.0% of water treatment agent, 8%-15% of composite rust protection corrosive, 12%-25% of compound emulsifier and the balance of deionized water. The environment-friendly concentrated solution for the hydraulic support has good freezing and thawing property, good hard water resistance, stable storage property and biodegradability, and good rust protection and corrosion resistant performances, and can be used for preventing a working solution from corroding equipment, thereby prolonging the service life of relative equipment and improving the safety. The environment-friendly concentrated solution has good lubricating property and airtightness and material compatibility, the abrasion and leakage of a support hydraulic moving part in a use process are effectively reduced, the cost for maintenance and use is lowered, and the requirement of the hydraulic support working in a harsh work condition can be met.

Description

technical field [0001] The invention relates to an environment-friendly concentrated liquid for hydraulic supports. Background technique [0002] The hydraulic support is an important mechanical equipment used to support the roof in the coal mining face in the coal industry; it is used in conjunction with the shearer. It not only realizes the comprehensive mechanization of coal mining, improves the working efficiency of coal mining and transportation equipment, but also ensures the life safety of underground coal mine work to the greatest extent. [0003] The hydraulic fluid is used as the transmission medium in the hydraulic support system, and the pressure or kinetic energy of the liquid is used to transmit energy. The lifting, moving and overload protection of the hydraulic support, the transmission of energy, lubrication, reducing the wear and friction of moving parts, preventing rust and corrosion, taking away frictional heat, and at the same time cooling, flushing and...
