Do you know how the thruster jack of the hydraulic support is composed? Today, I will introduce the structure of the thrust jack in detail.
A side thrust jack is a common hydraulic tool, which is mainly composed of piston rod assembly, cylinder block assembly, guide sleeve assembly, seal, etc. The piston rod assembly is one of the core components of the jack, including the piston rod, piston, seal, guide ring, etc., and the surface is chrome-plated to increase the ability to resist corrosion, abrasion, and smashing. The cylinder block parts are welded by the bottom of the cylinder and the cylinder barrel, which is one of the basic components of the jack. The connection between the guide sleeve assembly and the cylinder port includes internal threads, snap rings and glands, which are the guiding and supporting components of the jack.
The seals include mountain rings, drum rings, bud rings, JF dust rings, 0 type sealing rings, etc., which play the role of sealing and preventing leakage. When the side thrust jack is extended, the movable side guard plate moves outward, which can seal the frame gap and play the role of anti-gangue, anti-falling and frame adjustment.
When the side push jack is retracted, the movable side guard plate is retracted, which can reduce the resistance of the moving frame. In addition, side thrust jacks can also be divided into two types: mechanical jacks lift and descend through mechanical structures such as gears and levers, while hydraulic jacks lift and descend through hydraulic components such as hydraulic cylinders and hydraulic valves.
Through the introduction of this article, I believe you have a deeper understanding of the structure and working principle of the side thrust jack. If you find this article helpful, welcome to like and share!
