Hydraulic Control System

The electric and hydraulic control system of hydraulic support is the critical part for the mechanized working face to work productively and efficiently. Its energy transfer and conversion were realized by the hydraulic fluid containing high content of water as transmission medium. Nowadays we mainly use the simply treated mine water in the hydraulic fluid, and the treated mine water still contains various ions of suspension. Those impurities can damage some sensitive parts of the control system and result in the paralysis of the whole system in the worst case. Therefore, the quality control of the mine water used in the electric and hydraulic control system is very crucial. This paper is to examine the mine water quality index in conjunction with case study, discuss the negative effects of mine water on the electric and hydraulic control system, and propose scientific solutions.

Hydraulic support is an important equipment of mechanization caving coal in modernization coal mine. Hydraulic support strength test is a key link in hydraulic support design. Based on the similarity theory, the displacement, stress and strain information of test measured from hydraulic support model test can be popularized to hydraulic support prototype. This has an important significance on successful pass in prototype hydraulic support strength test and quicker and better designing eligible hydraulic support. The construction of load equipment and hydraulic control system of hydraulic support model test provides a practical and convenient research way of hydraulic support model test.
