Mining Suspension Type Hydraulic Prop

 

Our suspension type hydraulic prop uses high-strength materials and anti-corrosion treatment, which can be used for a long time in the harsh environment of the downhole, and the suspension type hydraulic prop has the characteristics of high pressure resistance, and the hydraulic system and structural design can withstand high roof pressure.

 
 
 

Underground DW Outer Injection Single Hydraulic Prop

Underground DW outer injection single hydraulic prop plays an important role in underground coal mine face support, roadway support, maintenance operations and other scenarios, and has a long history of use. And it has the characteristics of high safety, easy operation and strong adaptability.

 
 
 

Underground Mining Tunnel Hydraulic Supporting Prop

Underground mining tunnel hydraulic supporting prop has high strength and high reliability at the technical level, we have a stable supplier of raw materials, and the use of high-strength alloy steel to ensure that underground mining tunnel hydraulic supporting prop does not deform and break under high pressure, and our company has strict process control.

 

 

Basic Principles of Mining DW Suspension Type Hydraulic Prop

Mining DW suspension type hydraulic prop's working principle is: When liter column, the liquid injection piping system with three guns insert liquid injection valve body, hung locking sleeve, operating liquid injection gun, pump high-pressure liquid injection fluid through the top opening with three guns valve ball-type check valve, into the pillar, forcing the live cylinder rises.


When contacting metal hinged roof pillar roof beams and the top beam close to the face plate, live longer cylinder increases, the acrow prop's a pressure chamber in a very short time and the same pump pressure, and then release the gunner and pouring off the high pressure fluid pump, the three-way valve with the valve closed, so that acrow prop cavity remain constant.


External injection-type C-shaped handle body parts, welded at both ends of the outer wall of the cylinder is fixed, causing the handle body and cylinder can not be rotated relative to the operating space leading to outer single hydraulic prop is limited, inconvenient to use.

 

Precautions for the Use Of Mining DW Suspension Type Hydraulic Prop
 

When the mining DW suspension type hydraulic prop is in use, do not use it at the highest height.

 

Mining DW suspension type hydraulic props should generally be used in conjunction with metal hinged top beams.

 

For new mining DW suspension type hydraulic props and props used for the first time after restoration, the air in the inner cavity of the mining DW suspension type hydraulic props shall be discharged.

 

When supporting the mining DW suspension type hydraulic prop, flush the liquid injection valve body of the one-way valve with a liquid injection gun to avoid coal dust pollution and affect the performance of the valve.

 

When supporting mining DW suspension type hydraulic props, the direction of the liquid injection valve body of the three-way valve is toward the downward groove direction of the working surface.

 

Special drifting jacks should be used for migration, and the waist of the mining DW suspension type hydraulic prop should not be used as the fulcrum of migration.

 

Hard objects such as hammers and picks are not allowed to knock the cylinder body and three-purpose valve.

 

The retracted mining DW suspension type hydraulic props should be lowered to the lowest height, and immediately placed on the side against the old lint. It is forbidden to throw them on the bottom plate.

 

Liquid injection guns are not allowed to be placed randomly. After injection, they should be hung on the handle of the second row of mining DW suspension type hydraulic props.

 

When crushing, it is strictly forbidden to use blasting or deadlift with a post-returning machine. Undercover methods should be used to loosen the mining DW suspension type hydraulic props and then pull them out.

 

After-Sales Service Is Solemnly Promised

FAQ

 

Q: What is the working principle of a mining DW suspension type hydraulic prop?

A: Mining DW suspension type hydraulic prop's working principle is: When liter column, the liquid injection piping system with three guns insert liquid injection valve body, hung locking sleeve, operating liquid injection gun, pump high-pressure liquid injection fluid through the top opening with three guns valve ball-type check valve, into the pillar, forcing the live cylinder rises.

Q: What are the main components of a mining DW suspension type hydraulic prop?

A: The main components include the cylinder body, piston, piston rod, sealing components, and the hydraulic control system. The cylinder body is the main structure that holds the hydraulic fluid; the piston and piston rod convert the hydraulic pressure into mechanical force; the sealing components prevent hydraulic fluid leakage; and the hydraulic control system is used to control the movement and working state of the prop.

Q: What are the advantages of the DW suspension type hydraulic prop?

A: Engineered for superior load-bearing capacity, mining DW suspension type hydraulic prop ensures maximum safety and stability in demanding coal mining environments.

We're well-known as one of the leading mining dw suspension type hydraulic prop manufacturers and suppliers in China. Please feel free to buy high quality mining dw suspension type hydraulic prop from our factory. Good service and reasonable price are available.
