- What is cylinder buckling?What is cylinder buckling?It’s a sudden, large, and unstable lateral deflection. It can be associated with only a small increase in compressive load above a critical level, known as the buckling load. The corresponding stress can be far less than the yield strength of the rod material.
- What causes a hydraulic cylinder to leak down?What causes a hydraulic cylinder to leak down?Hydraulic cylinder drift is caused by internal leaks in the cylinder across the piston. The fluid physically moves from one side of the piston to the other which creates an uneven balance and causes the cylinder to move or “drift”.
- What is telescopic cylinder mis-staging?What is telescopic cylinder mis-staging?Mis-staging is a telescopic cylinder extending or retracting in the wrong sequence. When the cylinder tries to correct its sequence, rapid movement and violent slamming between moving stages can occur.
- Will increasing the hydraulic pressure make my cylinder go faster?Will increasing the hydraulic pressure make my cylinder go faster?Generally, no. Speed is a factor of flow. You need more flow to make things move faster.
- When is a telescoping cylinder used?When is a telescoping cylinder used?A telescoping cylinder is a cylinder employing several pistons which telescope into each other. This cylinder is used when a relatively long working stroke is needed for a short cylinder length. Telescopic cylinders are used in a variety of applications that require the use of a long cylinder in a space-constrained environment.

- What’s the difference between a hydraulic cylinder and a pneumatic cylinder?What’s the difference between a hydraulic cylinder and a pneumatic cylinder?Pneumatic cylinders rarely provide much more than a hundred pounds per square inch of pressure to the piston, whereas hydraulic cylinders are capable of anywhere from 1500 to 10,000 psi, which can be ten to hundred times the force of a pneumatic cylinder.
- What is a ram CylinderWhat is a ram CylinderA ram-type cylinder is a cylinder in which a cross-sectional area of a piston rod is more than one-half a cross-sectional area of a piston head. In many cylinders of this type, the rod and piston heads have equal areas. A ram-type actuating cylinder is used mainly for push functions rather than pull.

- What is the function of a hydraulic cylinder in a hydraulic system?What is the function of a hydraulic cylinder in a hydraulic system?The function of hydraulic cylinder is to provide linear motion. It converts the fluid energy into mechanical energy (linear movement). Cylinders are broken down into two main categories: pneumatic and hydraulic. Pneumatic cylinders can be operated by several types of gases, however, compressed air is by far the most common. Hydraulic cylinders can be operated with a very large range of fluids. By far the most common is petroleum based hydraulic fluid. Fire-resistant fluids are also common, they may be synthetic, or water based.
- What is a hydraulic cylinder?What is a hydraulic CylinderA hydraulic cylinder is a device which converts fluid power into linear mechanical force and motion proportional to the effective cross-sectional area of the piston. Their output force, or motion, is in a straight line. Their work applications may include pushing, pulling, tilting, and pressing. Cylinder type and design are based on specific applications. Cylinders usually consist of a movable element such as a piston and piston rod, plunger or ram, operating within a cylindrical bore. Common types of cylinders include double-acting, single-acting, and telescoping.

- What are the main types of hydraulic cylinders?There are three most common types of hydraulic cylinders:Tie-rod hydraulic cylinders,Welded hydraulic cylinders,Telescopichydraulic cylinders2019/7/15 15:49:37There are three most common types of hydraulic cylinders:Tie-rod: Tie-rod cylinders are not as strong as welded cylinders. They use one or multiple tie-rods to provide extra stability to the cylinder. These rods are mainly installed on the exterior of the cylinder and carry most of the load.Welded: Welded cylinders offer more in the terms of customization and strength. End caps are welded in place to close the case of the cylinder. Welded cylinders often have a narrow body and shorter overall length, enabling them to fit better in to tight spaces in machinery.Telescopic: Telescopic cylinders are multi-stage units that allow the cylinder’s stroke to be longer than a normal cylinder. In this case, the piston rod is also used as a piston barrel and a second piston rod is used for the consecutive barrel.
