There are many types of hydraulic machines that include large machinery, such as backhoes and cranes. Other types of smaller equipment include log-splitters and jacks. The brake on a vehicle is another example of a hydraulic system.Know More
An excavator at a construction site is an example of heavy equipment that takes full advantage of hydraulic systems. Not only is the large bucket that can dig up tons of material powered by large hydraulic cylinders, the tracks that move the machine around are also hydraulically powered. The diesel motor on board merely powers a hydraulic pump that moves fluid to slave cylinders.
A skid/loader is another example of heavy equipment that makes use of multiple hydraulic systems. All four wheels are powered by hydraulic motors independently, giving the machine great mobility. Raising and lowering the bucket, rotating the bucket to scoop or dump, and splitting and closing the bucket to grip objects all require separate hydraulic systems.
Hydraulic machines and systems consist of a basic setup where fluid is forced from one cylinder to another. These machines get their strength and efficiency through changing the size of one cylinder compared to the other, a principle called hydraulic multiplication. By trading distance for force, applying force to a piston in a small cylinder pushes fluid through hydraulic lines to a large cylinder, multiplying the end force the large cylinder piston exerts in proportion to the size difference of the two cylinders. The two cylinders are termed the master and slave cylinders.Learn more about Motion & Mechanics
A compound machine is a machine composed of two or more simple machines. Common examples are bicycles, can openers and wheelbarrows. Simple machines change the magnitude or direction of a force without any motor.Full Answer >
A machine is any device that transmits mechanical energy or power into useful work. The simplest machines redirect an applied force or convert kinetic energy into potential energy. More complicated machines are powered by electricity or fuel and use moving parts and electronic circuitry to complete complex tasks.Full Answer >
The hydraulic ram pump works by suddenly closing a valve in a water line to produce a surge in pressure that is collected in a pressure chamber. The process involves valves that automatically open or close depending on the pressure inside the pump.Full Answer >
There are two primary methods used within hydraulic valves. Some control hydraulic fluid flow by using a spool, bore and different ports, while others use one or more poppet valves. Both of these types of hydraulic valves are designed to control or change the direction of hydraulic fluid flow.Full Answer >
