Single Acting Multi Stage Telescopic Agricultural Truck Hydraulic Welding Cylinder

What's hydraulic cylinder?
A hydraulic cylinder is a mechanical actuator used to provide unidirectional Force through a unidirectional stroke. Hydraulic cylinders are used in almost every industry and are available in a variety of confiurations.
the two main types of hydraulic cylinders are Tie-rod and Welded.
Each of these cylinder types can have unique applications due to their designs.
Tie-rod cylinders are usually installed in light to medium duty applications and are generally designed to be repaired or re-packed if necessary.
Welded cylinders are designed for most applications and are more complex in Design, but are generally more diffiult to repair due to the welded design. Welded cylinders are typically a better solution due to their compact design and when a more robust design is important in an application.

Single Acting:

Single acting telescopic cylinders are the simplest and most common design

As with a single acting rod style cylinder the single acting telescopic cylinder is extended using hydraulic pressure, but retracts using external forces when the hydraulic pressure is removed and relieved to the reservoir

This external retraction force is usually gravity acting on the weight of the load

This external weight must obviously be sufficient to overcome the friction and mechanical losses within the machine design even after the work portion of the machine cycle has been accomplished. In the example above of the dump truck, the weight of the dump body now raised at an angle of 60, but empty of the load, most be enough to force the un-pressurized hydraulic fluid out of the cylinder and cause it to retract to the fully collapsed position.

Cylinder and Cylinder of the Advantages and Disadvantages:
1. As the hydraulic system uses pressure is generally in the range of 0.2-1.0Mpa, so the cylinder is the driving force can not do high-power components. Hydraulic cylinders can be done relatively large power device, use the hydraulic system;
2. From the media about the air can be unlimited, no cost and supply difficulties, the gas will be used directly into the atmosphere, convenient, no pollution, hydraulic oil is the opposite;
3. The air viscosity is small, the resistance to less than the hydraulic oil;
