Hydraulic SIngle Prop
- Single hydraulic prop is the mining supporting equipment, mainly used for blasting mining and advanced conventional working face’s back roof support as well as the comprehensive mechanized coal T-junction support.
The pillar is no longer the arc welding process thus, avoid roof collapse and other accidents
caused by the weld fracture.
Major structure
and pillar stress is only one fifth so the stability and security of pillar are improved, stability
coefficient reached 5 and the safety coefficient reached 3.
1.No Arc Weld:
The following problems may happen if the pillar uses arc weld:
First, it’s difficult to ensure the weld quality, so it’s common that leakage appears around the
commissure; second the arc weld weakened the strength and reliability of the plunger. So the DWX pillar
actually avoids roof caving accidents caused by weld fracture.
2.Seal-compensation and Seal-swelling:
The sealed points of the prop which uses seal-compensation and seal-swelling technique can effectively
compensate under the seal worning condition. And can contain the seal-compensation state while facing
the back roof pressure or under pressure support.
On the other side, all the sealed points mentioned above are external, so if any leakage happens, it can
be observed directly by eyes. Then we can infuse the infusion or replace it in time, to ensure the roof
can be perfectly supported and cleanup empty-propping hazard.
3.The Position of Three-use Valve:
The three use valve of DWX pillar is installed in the valve body, when the plunger rises the valve holds
its position and when the DZ pillar rises, the valve will follow up, as well as the hand of the operator.
However, for the thick seam mining, It’s not just increases the operation difficulty but also the dangerous
of the workers. So it’s very likely to cause harm to the operators. While type DWX pillar can avoid the danger
caused by the three use valve
Less Spare-parts Demand and Fewer Repairs:
Taking a 100mm working face as an example, the DZ pillars will be easy to leak and bend. In order to maintain
normal production, a certain number of reserves must be ensured. But for the DWX pillar, with its low damage
rate and applicability, can certainly reduce the spare reserves quantity, so that save a lot of money.
Alternate the Emulsion with Water as Working Medium
Security Benefits:
By improve the safety performance of the pillar; the cost saved by less casualties’ accident will be inestimable.
Technical parameters
Application
Single hydraulic prop is the mining supporting equipment, mainly used for blasting mining and advanced conventional
working face’s back roof support as well as the comprehensive mechanized coal T-junction support.
DWX single hydraulic prop is a new generation of monomer support products, due to its large carrying capacity,
the partial load ability, widely uses and so on, can be used in both thin coal seam and thick seam.
