Why force multiplication is key to how hydraulic systems work

What is force multiplication? Pascal's law states that pressure set up in a confined body of fluid, acts equally in all directions, and always at right angles to the containing surface. When a pressure is applied to a fluid trapped in a confined space, that pressure acts on each square millimeter of that surface. The force output of a hydraulic actuator is the result of the pressure applied, and the area to which that pressure is applied. If a given pressure is applied to two identical cylinders, then they will have an equal output force. How does force multiplication work? When the same pressure is applied to different sized cylinders, then the larger cylinder will have a greater force output. This is because the area which sees the hydraulic pressure is greater. The cylinder on the right in this example is twice the diameter of the cylinder on the left. The area of the circle multiplies the force The area of ...

The three types of hydraulic connectors and their two key functions

This article is an overview of the theory of hydraulic connectors, the three main types of connectors and the two key functions that all hydraulic connectors must fulfil. Three Main Types of Hydraulic Connectors It provides basic information about the three main classes of hydraulic connectors: Tapered Threads Metal seal connectors Soft seal connectors Two Key Functions of Hydraulic Connectors It’s important to understand that there are two functions that a hydraulic connector must fulfil: Holding Sealing Sometimes the holding and sealing functions are provided by the same mechanism, and sometimes by two different parts. Hose connectors may seem very confusing because of the many different types available. However, when looking objectively, connectors will always simply do two things. Hold, and seal under pressure. Development of Hydraulic Connectors Hydraulic connectors were developed in this order: Tapered threads Metal seal connectors Soft seal connectors Tapered Threads Tapered pipe threads were one of the first ways to connect pipes together. They involve cutting the pipe thread in a tapered manner, so that the diameter of the pipe changes over the length of ...
