An introduction to the hydraulic column backer
The hydraulic column backer is suitable for the application of retracting support equipment in coal mining working faces, and is especially suitable for single hydraulic pillar working faces. The most widely used model is the hydraulic column returner.
The use of the hydraulic column return device can greatly reduce the labor intensity of workers, save the time of column return, and improve the efficiency of column return. Because the column can be operated away from the column during column return, safety can be greatly improved. The hydraulic column return device requires an external hydraulic source, which is mainly composed of a hydraulic cylinder reversing valve and a traction chain.
2. Structural Features of Hydraulic Column Return Device
This product is mainly composed of hydraulic cylinder reversing valve and traction chain. The hydraulic cylinder is the main component of this product, and its structural features are as follows
The hydraulic cylinder is made of thick seamless steel pipes and has a surface anti-corrosion treatment.
The surface of the piston rod is chromium-plated, which has good anti-corrosion and wear resistance.
Using polyurethane sealing ring, it has good sealing performance and long service life
The traction chain adopts high strength and arc butt welding technology.
The reversing valve is a manual rotary valve, which is easy to use and has good sealing performance.
