The basis for all hydraulic systems is expressed by Pascal's law which states that anywhere upon an enclosed liquid is transmitted undiminished, in all directions, to the interior of the container. This principal allows large forces to be generated with relatively little effort. As illustrated, a 5 pound force exerted against a 1 inch square are creates an internal pressure of 5 PSI. This pressure, acting against the 10 square inch area develops a50 pounds of force. In a basic hydraulic circuit, the force exerted by a cylinder is dependent upon the cylinder bore size and the pump pressure.

Contact Us. Here are the basic four and a brief description of each. This is a tank or other container that holds the fluid to supply the rest of the system. Fluid Circuit. These are the pipes or hoses which transfer the fluid from one element of the system to another.
How Do I Hook Up A Hydraulic Valve? To extend cylinder, pull handle away from valve. When handle is released, the valve spring centers to neutral stopping cylinder. Neutral: Oil circulates from the pump through the valve and back to the reservoir. SystemStak is a revolutionary, compact system for sandwich-mounting modular valves between a directional control valve and a standard mounting surface. SystemStak gives you a full range of complementary pressure, flow and check valve functions, while saving space, reducing installation costs and increasing efficiency in hydraulic systems.
Hydraulic Pump. This device pushes hydraulic fluid through the circuit and provides the energy for the system to do its job.
Hydraulic control valve hookup
Hydraulic motor or cylinder. This is the component that causes something to movedriven by the power of the hydraulic pump.
Subcomponents that manipulate or regulate the fluid as it does its job include various valves which allow excess fluid to bypass the hydraulic motor or cylinder, control valves or valve spools, regulators, accumulators, pressure switches, and pressure gauges. Determine what type of power source your hydraulic system will require.
This can be an electric motor, and internal combustion engine, steam, wind, or water power. The main requirement is that the means for supplying the system with energy is that it is available and can generate sufficient torque for the purpose it is intended. Look at some simple, everyday hydraulic systems to help you become familiar with their function.
A hydraulic jack  X Research source can allow a small person to lift 20 tons of weight or more.
A power steering system on a car can reduce the force required to steer it considerably, and a hydraulic log splitter can force a steel wedge through even the toughest wood. Plan your hydraulic system project with the design parameters you will require.
You will have to choose a power delivery system to accomplish the task you are building your system for, an example would be using a hydraulic cylinder to split a log, or lift a heavy weight.
Determine the amount of work your system will do to allow you to size the components correctly.
A large capacity system will need a pump rated at a high volume, measured in volume per minutesuch as GPMor gallons per minute, and pressure, measure in weight per unit of areasuch as PSIor pounds per square inch. This being said, and typical hydraulic pump may deliver 0. The same applies to the hydraulic engine or cylinder you will use to driveor operate your machine. An example is a cylinder that lifts a set of forks on a forklift.
Choose the appropriate container for your hydraulic fluid reservoir. A steel or plastic tank that can have leak proof fittings attached to it to connect hoses or pipes will work. Remember, the reservoir is not pressurized when the system is operational, but you will need to vent it if you pipe excess fluid directly back to it through a bypass valve or other device.

Pick a suitable material to plumb up your hydraulic circuit. Reinforced rubber hoses with o-ring seals or flared fittings may be the easiest to route on your machine, but high-tensile steel tubing is more durable and requires less maintenance over time.
Find a suitable valve system for your task. Select the type of and capacity of your hydraulic pump. There are essentially two types of hydraulic pumps, a generator type, which forces oil between two or more meshed gears in a sealed housing, or a roller type, which operates with a number of cylindrical rollers configured around a cam in a sealed housing.
They each have advantages and disadvantages, so choosing one that performs to your machine's requirements is up to you.
Pair up a suitable motor to your pump. Pumps may operate off of a direct-drive shaft, a reduction gear drive, a chain and sprocket drive, or a belt drive.
Obviously each is more suitable in specific applications, and the choice depends on individual design criteria. Hook up your power application component. For simply moving an arm or lever on a machine, a hydraulic cylinder is your most likely choice. Another device that uses the hydraulic power supplied by the pump is a hydraulic motorseen used on winches and ground drive wheels on some types of aerial equipment, as well as manufacturing equipment like metal forming rollers.
Build a support frame that will position each component in a position where it will perform it's task.
This can be done on a flat surface, a metal framework, or even in multiple framed, remote function elements. An example would be having a pump, reservoir, and valve assembly on one platform, and having the hydraulic cylinder and support assembly in another location, as is found on hydraulic elevators in 2 to 4 story or even higher buildings. Fill the system with the hydraulic fluid you choose, bleed the air out of it, then pressurize it to check for leaks.
Now it should be ready to operate it to assess the function of the components. Without specific design criteria and engineering, it is likely you will need to tweak the finished product to optimize its operation. Yes No.

Yes, you just have to put a fitting on the hole that will not need oil and have some filter on it to keep out dirt, water and bugs. It's no big deal; double cylinders are used this way all the time. Not Helpful 1 Helpful 7.

Water density is not enough the generate the pressure needed on those pumps.
a manual hydraulic directional control valve Characteristics and configurations of manual directional control valves used in hydraulic systems - selecting the right valve for the job. Directional control valves are probably the most common of all hydraulic components and are used to control the starting, stopping and reversal of flow in a system. The key part of hydraulic solenoid control valve is the spool, it likes the heart of the valve, moves at linear motion always while the valve is working, therefore, in order to improve the service life of hydraulic solenoid control valve, the spool must has High wear resistance, and the raw materials must achieve a certain surface hardness. The simplest hydraulic circuit consists of a reservoir, pump, relief valve, 3-way directional control valve, single acting cylinder, connectors and lines (as shown in Figure 2). This system is used where the cylinder piston is returned by mechanical force.
