In other words, the single hydraulic prop, we know the classification of the single hydraulic prop, it has DN type single hydraulic prop and DW type single hydraulic prop. Below we focus on the DW type of single hydraulic prop applicable scope. Here, small make up to remind you to click DW single hydraulic prop will let you see a different colorful world.
DW single hydraulic prop, DW series external injection type single hydraulic prop, with the metal roof beam, for the coal mine general mechanized coal face support roof, also for the comprehensive mechanized coal mining working end support, suitable for the coal seam dip less than 25° gently inclined mining face. Take certain safety measures, can also be used for the Angle of 25° - 35° mining face. The working medium is an emulsion containing M10 emulsified oil 2%.
DW single hydraulic prop adopt plunger type suspension technology principle, make the hydraulic lift force directly through the inner cavity of individual hydraulic prop live column effect on roof, make the hydraulic lift force split the about four 5 of the work resistance of the hydraulic prop, make live column in the stress of the shaft up only about one 5 of the working resistance, improve the stability and security of the props, also greatly improved the pillars support the height and load capacity. The arc welding seam which is difficult to be guaranteed by the process is cancelled on the live column, which improves the strength and safety reliability of the props, avoids the leaking of the props caused by the weld fracture, eliminates the hidden danger of accidents such as roof caving, and guarantees the safety of underground workers with max limit.
