Hydraulic Pressure Cylinder Double Acting Working With NBR Adjustable Stroke In Alignment

Working theory description:

The double-acting feature of this hydraulic cylinder means that it can exert force in both directions, both extending and retracting the piston. This is achieved by the use of two hydraulic ports, one on each end cap, which allow hydraulic fluid to flow into and out of the cylinder.

When hydraulic fluid is pumped into one of the ports, it pushes the piston in one direction, extending the cylinder. When the fluid is pumped into the other port, it pushes the piston in the opposite direction, retracting the cylinder. The tie rods ensure that the cylinder assembly remains stable during these movements.

Double-acting tie-rod hydraulic cylinders are used in a wide range of applications, including construction equipment, agricultural machinery, and industrial machinery. They are preferred for their durability, strength, and versatility.

Stroke calculation:

For example : a cylinder has 80 mm bore,45mmrod , rod end with FA type ,and workingpressure 100kgf/cm2

ans : 1.based on FA type, table 1 shows

2.with n=2 and table 2,L can be foundas 1980mm

3.based on FA type and extermal dimensions 

l=F+W+H+CA=24+35+18+75=152mm

4.max.storke S=L—l=1980-152=1828mm

Alignment steps:

1.Turn lock nut towards counter clockwise with 1/4circle by wrench.

2.Using hex . wrench to adjust thealignment screw B:

1)clockwise, rod speed will be slow down

2)counter clockwise, rod speed will be up.

3.After alignment ,use hex. wrerch to fix thealignment screwB,and then tighten thecushion nut C to prevent possible

leakage from cushion seal D

4.Tighten the lock nut A

Standard=A:input port    B:Cushion position    D:Check valve position

e.g:order form for position HCA70-LA-C-100X200-B-B-A

Input port=B position

Cushion=A position

	32--63	20	10
	80--160	25	15
	180--224	30	27
	250	35	32

• Should the movement of a cylinder with loading is above 500mm/sec.,
• If the moving speed is higher than 750mm/sec,external reducing speed valves should be used

The application not only for production mechanical machine tools and metal processing equipment, but also can be widely used in actuators of steel, nuclear power plant control, passenger elevators, etc

 Why tie rod hydraulic cylinder?

Tie rod hydraulic cylinders are a specific design of hydraulic cylinders characterized by the use of tie rods to hold the cylinder together. Here are some reasons why tie rod hydraulic cylinders are commonly used:

Cost-Effective Design: Tie rod cylinders are generally more cost-effective to manufacture compared to welded or threaded body cylinders. The tie rods provide structural support, allowing for a simpler and more economical construction.

Easy Maintenance and Repair: The tie rod design facilitates easier maintenance and repair. In the event of damage or the need for maintenance, the tie rods can be easily removed, allowing access to internal components without disassembling the entire cylinder.

Modularity: Tie rod cylinders are often modular in design, making it easier to replace individual components or upgrade specific parts. This modularity can contribute to faster and more cost-efficient repairs.

Versatility: Tie rod cylinders are available in a wide range of sizes and configurations, making them versatile for various applications. They can be easily adapted to different specifications and requirements.

High Pressure Ratings: Tie rod cylinders are capable of handling high-pressure applications. The tie rods add structural integrity, allowing these cylinders to withstand higher pressures without compromising safety or performance.

Wide Range of Applications: Tie rod hydraulic cylinders are suitable for a broad spectrum of applications, including industrial machinery, construction equipment, and material handling systems.

Customization: Manufacturers can easily customize tie rod hydraulic cylinders to meet specific application requirements, such as stroke lengths, bore sizes, and mounting options. This flexibility makes them adaptable to diverse industrial needs.

While tie rod cylinders have their advantages, it's essential to consider the specific requirements of the application when choosing a hydraulic cylinder design. Factors such as load capacity, operating conditions, and budget constraints will influence the selection of the most appropriate hydraulic cylinder type.
