LAP 2 - Hydraulic Cylinder Applications

Introduction:

Hydraulic cylinders are used in many applications. To meet the needs of these applications, special cylinder types, options and circuits are often needed. In this LAP, you will learn about some of the circuits which are used to increase the speed of a cylinder and maintain its speed even when load changes.

Objectives:

- Describe the operation of four types of cylinders and give the application of each.
- Describe the construction of two types of cylinders and give an application of each.
- Describe three common cylinder mounting styles and give a application of each.
- Describe three common cylinder feature options.
- Describe the principle of cylinder regeneration and name an application.
- Describe the operation of a basic regeneration circuit.
- Describe how to calculate the extend speed of a cylinder in regeneration.
- Describe how to calculate the extend force of a cylinder in regeneration.
- Describe the function of a pressure-compensated flow control valve and name one application.
- Describe the operation of a pressure-compensated flow control valve and give its schematic symbol.
- Describe the function of a double-rod cylinder and name one application.
- Describe the operation of a double-rod cylinder and give its symbol.
- Define cylinder synchronization and name three applications.
- Explain why cylinders do not operate in synchronization.
- List and describe the operation of five methods used to synchronize cylinders.
