The monolithic hydraulic prop has a simple overall structure and a long service life; it is easy to operate and easy to maintain, and can greatly reduce the rate of prop lifting and maintenance. The single hydraulic prop is suitable for inclined coal seam mining face with coal seam inclination angle less than 25 degrees to 35 degrees. The adaptable conditions of coal seam roof and floor are: backward roof does not affect the recovery of the pillar, the floor should not be too soft, and the depth of the pillar pressed into the floor Deteriorate the integrity of the bottom plate, otherwise the base should be enlarged.
Suspension single hydraulic props, as the name implies, are developed on the basis of ordinary single hydraulic props, using plunger suspension technology, so that the hydraulic pressure directly acts on the top cover in the inner cavity of the single prop, the suspension hydraulic prop force greatly shares the hydraulic pressure The working resistance of the pillar and the upward force of the movable pillar are greatly reduced, which greatly improves the stability and safety of the pillar, improves the bearing capacity of the hydraulic pillar, and can also increase the bearing height of the pillar.
What are the main parts and materials of suspended single hydraulic props?
Cylinder / plunger (piston rod) 27MSiMn alloy steel is quenched and tempered .. Other top cover base 35-45 steel forging
What are the components of the single hydraulic prop accessories?
The accessories of the single hydraulic prop are usually: oil cylinder, movable column, handle body, unloading handle, three-way valve, injection gun, piston, connecting wire, return spring, top cover, cylindrical pin and single post seal: O-ring, anti-extrusion ring, dust ring, leather cup, J-ring, Y-ring and other accessories.
