Hydraulic Regeneration Circuit

A typical hydraulic cylinder have a larger extending force than retracting because of the area difference between full bore and annulus sides of the piston. Hydraulic regeneration system can be use to equalize the force. The example hydraulic regeneration circuit … Continue reading

Hydraulic Cylinder Construction

Typical construction for cylinders used in industrial applications is shown in Fig. 7.18. The seals are a key feature, as is the rod wiper. Dirt from the environment settles on the rod and will ingress into the hydraulic system if … Continue reading

Hydraulic Cylinder Failure

Standard cylinders are not designed to take a side load. Care must be taken to ensure that binding does not occur during extension or retraction. A designer will use one of the mounting methods shown in Fig. 7.15 to prevent … Continue reading

Hydraulic Cylinder Selection

Cylinder manufacturers typically classify their products as heavy duty, medium duty, and light duty. Pressure ratings up to 6000 psi are available. Some manufacturers build an agricultural-grade cylinder. These cylinders are satisfactory for applications where annual use is limited. A … Continue reading

Hydraulic Cylinder Cushioning

When cylinders reach the end of their stroke, the pressure rises quickly, creating a shock wave in the hydraulic circuit. Cushioning is done to reduce this stock. The concept, shown in Fig. 7.6, is quite simple. First, we consider the … Continue reading

Basic Concept of Hydraulic Cylinder

Suppose a flow of fluid is delivered to a hydraulic cylinder, causing it to extend. The cylinder has a cross-sectional area A and delivers a force F while moving a distance x (Fig. 1.2). The distance moved is related to … Continue reading
