Introduction of Dw Good Quality And Complete After-Sales Service New Products For Sale Acrow Hydraulic Roof Support Prop

DW Outer Injection Coal Mining Single Hydraulic Prop increasingly widely used in the production of its traditional wooden pillars supporting metal friction compared with high recovery, supporting safe and reliable, working resistance constant, setting load is high, the use of flexible benefits. 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.zmwm11
