Adopting the principle of plunger suspension technology, the sealing cover in the living column bears four-fifths of the suspension hydraulic prop working resistance, and the stress of the living column is only one-fifth. Greatly improve the stability, safety, carrying capacity and anti-deflection ability of the pillar.
There is no longer arc welding seam on the living column, which is difficult to guarantee the process, and the strength and reliability of the column are also improved, avoiding the hidden danger of roofing and other accidents caused by the fracture of the welding seam, and ensuring the safety of the staff.
According to different steel acrow props specifications, the weight of the whole steel acrow props is reduced by more than 15-30% compared with the existing pillar products, the minimum height of the pillar is greatly shortened, and it is very convenient to move, transport and use.
The work schedule is large, which expands the scope of use. In particular, the sinking work surface of the top plate not only facilitates the return of the column, but also improves the recovery rate of the steel acrow props, reduces the consumption of the pillar, and reduces the production cost.
The DWX series hydraulic prop are externally leaked and can be visually inspected visually. Once the pillars are leaked, they can be injected or replaced at any time, eliminating the need for cumbersome inspection work, and the staff does not have to worry.
The DWX prop three-purpose valve is set on the handle body. When injecting liquid, the three-purpose valve does not rise with the rise of the movable column of the prop. It is easy to operate, safe and reliable.
Each sealing point of the DWX hydraulic prop adopts the principle of seal compensation and seal tightening technology. In the case of seal wear, it can effectively compensate. The replacement rate of the seal is reduced, and the maintenance cost is reduced.
The DWX type hydraulic prop adopts a special nitriding process surface treatment process or a nickel-phosphorus plating process process to achieve corrosion resistance and wear resistance. The working medium can also use the underground neutral water of the coal mine, which is an ideal environmental protection type coal mining face support equipment.
The DWX type suspension hydraulic prop has a large working stroke and a wide range of use. Each specification can replace the 2-4 specifications of the DZ type pillar series, reducing the variety of specifications, bringing convenience to pillar management, and reducing the equipment cost and management of the pillar. cost.
The use method of suspension type single hydraulic prop hopes to be helpful to everyone, want to know more information, pay attention to the future news of our hydraulic prop manufacturer.
