DW63 series of mine hydraulic prop use: The DW63 series of mine hydraulic prop metal splices top beam or column cap matched for height is less than 1.6 m high inclined seam Roof pressure not slow inclined seam; stope can be used to support most of the working face ends; pillars of use for unstable or broken roof, as the recent coal wall stickers temporary help. DW mining hydraulic prop structure and working principle: the pillars are outside for liquid pillar Bore ∮ 63mm, pillars of the main cylinder, a plunger, piston, cover, base, return spring, rubber seals, three valves component parts. DW mining hydraulic prop face pumping station, three valves working medium water injection to the column, mobile column by the its top top beam contact, keep some early support pressure, so that a single column in Supporting the work of the state. Roof pressure suddenly increased its rated operating pressure exceeds a single column resistance, three valves in the safety valve will automatically open row night single column constant at the rated working resistance within the roof pressure is evenly distributed around single column to the face support security and reliable. Need to shift the column, as long as the rotation of the Royal upload wrench column within the working fluid through the the three valves Royal overload valve discharge, mobile column of the internal reset spring decline. DW mine hydraulic prop use: the pillars can be widely used in roof pressure is not strong gently inclined, inclined and steep seam; the living pillar column coating galvanized phosphating passivation process, can be used for blasting mining apheresis face; pillar base ∮ 120, ∮ 160 two, should be used for loose floor ∮ base area of ??160 or greater; When large inclination angle, for example, when more than 35-45 degrees, in order to avoid the pillars fall should support set together with the pillar when the lever of the adjacent pillars pull lateral soft connecting each other, at the same time to ensure the safety of prop.
