Problems solved by technology

However, there is currently no relevant system for quality control of water as a working medium in this field
In practical applications, unqualified water is likely to cause rust and corrosion of related components in hydraulic support equipment.
This will undoubtedly greatly reduce the service life of hydraulic support equipment and increase maintenance costs during mining operations

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] figure 1 An embodiment of a working medium protection system 200 for a coal mining face according to the present invention is schematically shown.

[0024] Such as figure 1 As shown, the system 200 includes a working medium using mechanism, such as a hydraulic support 209 . The system 200 also includes a working medium storage mechanism, such as a floating top liquid tank 205 . The system 200 also includes a first monitoring mechanism 206 , which is connected between the floating roof tank 205 and the hydraulic support 209 , so as to inspect the quality of the working medium supplied from the floating roof tank 205 to the hydraulic support 209 . When the first monitoring mechanism 206 detects that the quality of the working medium is not up to standard, it stops supplying the working medium from the floating roof tank 205 to the hydraulic support 209 .

Abstract

The invention relates to a water medium guarantee system for a coal face, and a water medium is used as a working medium. The system comprises a working medium using mechanism, a working medium storage mechanism and a first monitoring mechanism, wherein the working medium storage mechanism communicates with the working medium using mechanism so as to provide the working medium for the working medium using mechanism, the first monitoring mechanism communicates between the working medium storage mechanism and the working medium using mechanism and is used for detecting the quality of the workingmedium flowing from the working medium storage mechanism to the working medium using mechanism, and when the first monitoring mechanism detects that the quality of the working medium does not reach the standard, the working medium is stopped from providing for the working medium using mechanism from the working medium storage mechanism. The system is beneficial to reducing maintenance cost in themining operation process.

Description

technical field [0001] The invention relates to the technical field of coal mine mining protection, in particular to a working face water medium protection system. Background technique [0002] Coal mining face refers to the first production site of coal, which is an important area used to arrange coal mining related equipment and carry out coal mining work. The above coal mining related equipment includes hydraulic support equipment for coal mining, which also includes pumps, valves, oil cylinders, pipelines and many other devices that need to use working media to operate. [0003] At present, the commonly used working medium is emulsion. Emulsions require the mixing of water and oil in a special dosing device. However, under the current technical conditions, it is difficult to stabilize the mixing ratio of the emulsion, and it is also difficult to accurately determine the mixing ratio of the emulsion. In addition, for some operating scenarios, it does not have sufficien...
