Cylinder body:
The cylinder is the main part of the Adjustable Props and is usually made of high-strength alloy steel.
It has an internal cavity to hold the hydraulic fluid and piston assembly.
Piston assembly:
The piston assembly is located in the cylinder body, including the piston and piston rod.
The piston rod is sealed to the cylinder body by a seal to prevent hydraulic fluid leakage.
When hydraulic fluid enters the cylinder, it pushes the piston and piston rod along the cylinder to change the height of the strut.
Bottom Valve:
The bottom valve is located at the bottom of the cylinder and is used to control the inflow and outflow of hydraulic fluid.
It is usually a check valve that allows hydraulic oil to enter the cylinder under pressure, but prevents it from flowing out.
Pilot Operated Check Valve:
A Pilot Operated Check Valve is another important control element that allows hydraulic fluid to flow in the reverse direction under certain conditions.
This is usually achieved through a control line that opens when the pressure in the control line reaches a certain level, allowing the hydraulic fluid to flow out of the cylinder.
Triple purpose valve:
A triple purpose valve is a control valve that integrates multiple functions, usually including an unloading valve, a safety valve, and a fluid injection valve.
The unloading valve is used to relieve pressure in the strut in order to lower the strut if needed.
Safety valves are used to prevent the pressure in the strut from becoming too high, thus protecting the strut from damage.
The fluid injection valve is used to inject Hydraulic Prop fluid into the strut to ensure its proper functioning.
Piston Rod:
The piston rod is the part that connects the piston to the top of the strut, and it transmits the thrust of the hydraulic fluid to the top of the strut.
Piston rods are usually made of high-strength materials to ensure that they can withstand sufficient pressure and bending forces.
Column Head:
The ram head is located at the top of the strut and is used to connect to the top plate or other supporting structure.
