Application of Accumulator in Walking-type Hydraulic Support

The basic composition and application conditions are introduced about walking-type hydraulic support,the working process of hydraulic support are discussed in detail.The problem of pressure falling is proposed for walking-type hydraulic support in the working process,the reason of pressure drop is analyzed and a new solution is proposed. The detailed theory and data demonstrate that this scheme is practical and scientific.It provides a new idea for the hydraulic system, which also needs pressure keeping-up equipment,and it has a very practical significance.
