The suspension type single hydraulic prop adopts the principle of plunger suspension technology, the suspension force reaches four-fifths of the working resistance, and the vertical column is only one fifth of the force. The DWX type prop three valves are set on the handle body, when filling liquid, the three-valve does not rise with the live column of the prop, which is easy to operate, safe and reliable. Single hydraulic prop is a new generation of single support product of working face developed by China university of mining and technology.
The suspension type single hydraulic prop is suitable for the roof support of coal mining working face, the end roof support of fully mechanized mining working face and the advance support of roadway excavation. Due to its large bearing capacity, strong anti-deflection load capacity, large working stroke and wide range of use, it can be applied to thin coal seam, medium thick coal seam and thick coal seam working face. DWX type single hydraulic prop adopts the principle of plunger suspension technology, the suspension force reaches four-fifths of the working resistance, and the vertical column is only one fifth of the force. DWX type prop three valves are set on the handle body, when filling liquid, the three-valve does not rise with the live column of the prop, which is easy to operate, safe and reliable.
Differences between suspension single hydraulic prop and ordinary single hydraulic prop:
Suspension single hydraulic prop and ordinary single hydraulic prop is the difference between the large travel, compared with the same specifications of the individual prop light weight, in addition to the two big advantages, there are other these advantages: has the strong ability of partial load resistance and the stability of the larger, use neutral water, reduce costs, repair and maintenance cost is low, use rise more convenient, more convenient transportation; High stability at home and abroad, the internal leakage of the prop caused the virtual top of the pillar, and even caused the pillar to fall automatically and injury accident hidden danger. All sealing points of DWX type prop are peripheral, which can be visually inspected. Once the pillar leaks, the prop can be injected or replaced at any time, ensuring the safety and reliability of roof support of coal face. DWX prop has no stigma, no piston and no arc weld, which simplifies the structure of the prop and improves the safety. Its live column and cylinder are integral structure, the strength is big, the stability is good.
