Outer single hydraulic prop can be used alone or in combination with metal hinged roof beams supporting the use, can be used in coal seam dip is less than 25. Stope roof gently inclined to pay, but also for mechanized coal face end support or temporary support available.DW Outer Injection Coal Mining Single Hydraulic Prop is mainly composed of living, fuel tanks, three valves, cover, base body, reset spring handle body and a piston.DW Outer Injection Coal Mining Single Hydraulic Prop's working principle is: When liter column, the liquid injection piping system with three guns insert liquid injection valve body, hung locking sleeve, operating liquid injection gun, pump high-pressure liquid injection fluid through the top opening with three guns valve ball-type check valve, into the pillar, forcing the live cylinder rises; When contacting metal hinged roof pillar roof beams and the top beam close to the face plate, live longer cylinder increases, the acrow prop's a pressure chamber in a very short time and the same pump pressure, and then release the gunner and pouring off the high pressure fluid pump, the three-way valve with the valve closed, so that acrow prop cavity remain constant. Currently, external injection-type C-shaped handle body parts, welded at both ends of the outer wall of the cylinder is fixed, causing the handle body and cylinder can not be rotated relative to the operating space leading to outer single hydraulic prop is limited, inconvenient to use. In addition, the DW Outer Injection Coal Mining Single Hydraulic Prop uses emulsion, prone to corrosion.zmwm11Product ParametersParameters of Dw Good Quality And Complete After-Sales Service New Products For Sale Acrow Hydraulic Roof Support PropTypeUnitDW35DW31.5DW28DW25DW22DW20DW18DW16DW14DW12DW10DW08DW06Max Heightmm35003150280025002200200018001600140012001000800600Min Heightmm27002350200017001440124011101005900792685578485 Working Strokemm800800800800800760690595500408315222145Net Weightkg82.876.4705855494743.639.936.33226.726.5Rated ResistancekN150200250300Rated Fluid PressureMpa19.125.531.838.2First Sustaining LoadkN118--157Pump Station PressureMpa15or20Column Lifting Speedmm/s≥60Column Descending Speedmm/s≥40Diameter of Oil Cylindermm100Base Areacm2113109Service Substance Coal 10 (M10)Emulsifier(or MDT10emulsifier)1-2% EmulsionDetailed PhotosImages of Dw Good Quality And Complete After-Sales Service New Products For Sale Acrow Hydraulic Roof Support PropCompany Profile
