Now let's get to know the suspension type single hydraulic prop, it is a constant resistance single hydraulic prop with external liquid supply, it is the supporting equipment of the mechanized general mining face, and it is also the end support of the fully mechanized mining face device. It is suitable for roof support and end roof support in coal mining face. Because of its large bearing capacity, strong anti-eccentric load capacity, large working stroke and wide range of use, it can be applied to thin coal seams, medium-thick coal seams and Thick coal seam face.
Features of suspension type single hydraulic prop:
1. Has a strong anti-eccentric load capacity and greater stability.
The suspension type single hydraulic prop adopts the principle of plunger suspension technology, so that the hydraulic suspension force acts directly on the top cover through the inner cavity of the prop living column, so that the hydraulic suspension force shares about four fifths of the working resistance of the prop The axial force of the column is only one-fifth of the working resistance, which improves the stability and safety of the prop, and also greatly improves the support height and bearing capacity of the prop.
2. High reliability
Suspended single hydraulic props are no longer provided with arc welding seams that are difficult to guarantee, but also improve the strength and reliability of the column, avoid the hidden danger of roofing and other accidents caused by the welding seam fracture, and ensure the safety of the staff .
3. Light weight
According to the different pillar specifications, the weight of the entire column is reduced by 15-30% compared with the current domestic and foreign props, but its working resistance, working stroke and stability safety factor are higher than those of aluminum alloy props.
4. Large working schedule
The suspension single hydraulic prop has a large working stroke, which expands the scope of use, and can also reduce the specifications of the prop, especially the working surface with a large sinking roof.
5. High strength
All sealing points of suspended single hydraulic props are peripherals and can be visually inspected visually. Once the props leak, they can be injected or replaced at any time to ensure the safety and reliability of the roof support of the coal mining face.
6. Easy to use
The three-purpose valve of the suspension type single hydraulic prop is set on the handle body. When the liquid is injected, the three-purpose valve will not rise with the rise of the living column, and the operation is convenient, safe and reliable.
7. Low repair and maintenance costs.
