Overview of Suspended Single Unit Hydraulic Support Products
Suspended single hydraulic support is a type of externally supplied constant resistance single hydraulic support, which is a supporting equipment for mechanized general mining face and also an end support equipment for comprehensive mining face. It is suitable for roof support and end roof support of coal mine mining faces. Due to its high bearing capacity, strong resistance to eccentric load, large working stroke, and wide range of use, it can be applied to thin coal seams, medium thick coal seams, and thicker coal seam faces.
Product structure of suspended single hydraulic prop
The suspended single hydraulic prop consists of 1. top cover 2. sealing cover assembly 3. movable column 4. handle valve body 5. oil cylinder 6. reset spring 7. base S, three-way valve 8, 14. O-rings 9, 13, 15. retaining ring 10. elastic cylindrical pin 11. dust ring 12. Y-shaped sealing ring 16. connecting steel wires 17, 18, guide ring and other components.
Characteristics of suspended single hydraulic prop products
1. It has strong resistance to eccentric load and significant stability.
The suspended single hydraulic pillar adopts the principle of plunger suspension technology, which allows the hydraulic suspension force to directly act on the top cover through the inner cavity of the pillar's active column. The hydraulic suspension force shares about four fifths of the pillar's working resistance, and the axial force on the active column is only one-fifth of the working resistance, improving the stability and safety of the pillar and greatly increasing its support height and bearing capacity.
2. High reliability
The suspended single hydraulic support column no longer has circular arc welds that are difficult to guarantee in the process, which improves the strength and reliability of the column, avoids potential accidents such as roof collapse caused by weld fracture, and ensures the safety of workers.
3. Lightweight
According to the different specifications of the pillars, the weight of the entire pillar is reduced by more than 15-30% compared to the currently used pillars at home and abroad, but its working resistance, working stroke, and stability safety factor are higher than those of aluminum alloy pillars.
4. Large work schedule
The suspended single hydraulic prop has a large working stroke, which expands its range of use and can also reduce the variety of prop specifications, especially for working surfaces with large roof subsidence
5. High strength
All sealing points of the suspended single hydraulic pillar are external devices that can be visually inspected. Once the pillar leaks, it can be filled with liquid or replaced at any time, ensuring the safety and reliability of the roof support of the coal mining face.
6. Easy to use
The three-way valve of the suspended single unit hydraulic support is located on the handle body. When injecting liquid, the three-way valve will not rise with the rise of the active column, making it easy to operate, safe and reliable.
7. Low maintenance and repair costs.
8. Use neutral water.
