Suspension single hydraulic prop introduction

Suspension is single hydraulic prop is a kind of external fluid for constant resistance type single hydraulic prop, it is a high grade mechanization of conventional mining equipment, is fully mechanized working face end support equipment. It is suitable for the coal mining working face roof support and end roof support, due to its large carrying capacity, the partial load ability, work schedule, using range is wide, so it can be used in thin coal seam, medium thick seam and thick seam working face.

Suspension single hydraulic prop structure

Suspension single hydraulic prop by 1, top 2, hermetic seal component 3, live column 4, hand body 5, and 6 cylinder, reset spring 7, the base S, three with o-type ring valve 8, 9, 9, 13, 15, 10, elastic dowel pin retainer 11, 12, 16 y-shaped sealing ring, dust ring connection wire of 17, 18, guide ring and other components.

Suspension single hydraulic prop feature

1.Has strong ability of partial load resistance and greater stability.Suspension single hydraulic prop with plunger suspension technology principle, make the hydraulic lift force directly through the role of the inner chamber pillar live column on the roof, make the hydraulic lift force split the about four 5 of the support working resistance, 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 pillar, also greatly improved the pillars support the height and load capacity.

2.Suspension on the single hydraulic prop are no longer a process is difficult to guarantee the arc weld, also raised the pillar of strength and reliability, avoids because of weld fracture caused by roof caving accident hidden danger, ensure the safety of staff.

3.light weight

Pillar according to the different specifications, the whole column weight than the current pillar at home and abroad to reduce 1 5-30%, but the working resistance, working stroke and stability safety factor is higher than that of aluminum alloy pillar

4.long work schedule

Suspension single hydraulic prop working stroke, expand the scope of use, also can reduce the pillar of the specifications of the varieties, especially working face with large Numbers of roof convergence.

5. great strength

6.Suspension of single hydraulic prop with three valve in hand on the body, when the filler, three valve can't be with live column rises, convenient operation, safe and reliable

7 .Repair and maintenance costs low。

8.Use neutral water。
