 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.
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 warning 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 cleanupempty-propping hazard.
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
