Telescopic Hydraulic Cylinder
Multi-stage hydraulic cylinders include telescopic cylinders. This is essentially a set of sleeves or tubular rods acting as a linear actuator. In a telescopic hydraulic cylinder, four or five sleeves are nestled inside of one another, and the rod’s diameter decreases progressively with each sleeve. When the fluid enters a Telescopic hydraulic cylinder, it first enters the largest sleeve or main barrel, which then starts to lengthen. When the barrel is expanded to the highest-level fluid eventually enters the next sleeve or stage. In the Telescopic hydraulic cylinder, the fluid is moved in this fashion from one sleeve to the next.
Even though the force is kept constant, the fluid pressure rises as the diameter of the sleeves shrinks. In this manner, the liquid eventually reaches the plunger, the final sleeve.
Types of telescopic hydraulic cylinders:
- Single-acting telescopic cylinders
- Double-acting telescopic cylinders
- Combination of single- and double-acting telescopic cylinders
Single-Acting Telescopic Cylinders
The most popular kind of cylinders are single-acting ones, which operate either through the force of gravity or a retraction spring.
Double-acting telescopic cylinders
When a cylinder is double-acting, fluid pressure is exerted to both sides of the piston inside the cylinder. Hydraulic cylinders with double action for telescopic arms are typically seen in big, stationary installations.
What are some applications for telescoping hydraulic cylinders?
Telescopic hydraulic cylinders are utilised for these activities when the hydraulic cylinder’s typical operating stroke is not practical for the purpose. Actually, telescopic hydraulic cylinders work best in situations when a long stroke is needed but a small retraction distance. The Telescopic hydraulic cylinders’ nested construction is their major benefit for saving space. Because of their small size and ability to be put in places where larger settings are not possible but sufficient hydraulic push is still needed, telescopic hydraulic cylinders are frequently seen in dump beds and trailers.
