Speaking of single hydraulic props, we all know the classification of single hydraulic props, it has DN single hydraulic props and DW single hydraulic props. Below we focus on understanding the scope of application of DW-type single hydraulic props. Here, the editor reminds everyone to click on the DW single hydraulic prop to let everyone see a different multicolored world.
DW single hydraulic props, DW series external injection single hydraulic props, cooperate with the metal roof beam, used for supporting the roof of the general mechanized coal mining face of the coal mine, or for the support of the end of the comprehensive mechanized coal mining work, suitable for Slowly inclined mining face with coal seam inclination angle less than 25 °. With certain safety measures, it can also be used in the mining face with an inclination angle of 25 ° -35 °. The working medium adopts an emulsion containing 2% of M10 emulsified oil.
DW type single hydraulic prop adopts the principle of plunger suspension technology, so that the hydraulic levitation force acts on the top cover directly through the inner cavity of the single hydraulic prop living column, so that the hydraulic levitation force shares four fifths of the working resistance of the hydraulic prop left and right, the stress of the movable column in the axial direction is only one fifth of the working resistance, which improves the stability and safety of the prop, and also greatly improves the support height and bearing capacity of the prop. The arc welding seam that is difficult to guarantee the process is eliminated on the living column, which improves the strength and safety reliability of the prop, avoids the false roof of the prop caused by the leakage of the weld seam, and eliminates the hidden danger of roofing and other accidents. Limits ensure the safety of underground workers.
