The accepted international standard for maximum working pressure in the high pressure hydraulic tools industry is 700 Bar (10,000 PSI) and the majority of the products offered by Hi-Force are in line with this standard.
What determines pressure in a hydraulic system?
Two factors determine the hydraulic system pressure: the surface area of the piston and the size of the force produced by the machine through that piston .
How do you calculate hydraulic fluid pressure?
The basic equation to use is F (Force) = P (Pressure) x A (Surface Area) . You can rearrange the equation to solve for pressure using P = F/A.
Is hydraulic fluid pressurized?
Hydraulic fluid is dangerous. Fluid can escape when adjusting or removing equipment. Fluid can be trapped in the hydraulic system even when the engine and hydraulic pump are stopped. Trapped fluid can be pressurized in excess of 2,000 psi .
What is the role of pressure in hydraulics?
The science behind hydraulics is called Pascal’s principle. Essentially, because the liquid in the pipe is incompressible, the pressure must stay constant all the way through it, even when you’re pushing it hard at one end or the other. Now pressure is defined as the force acting per unit of area .
How do you control the pressure in a hydraulic system?
Pressure control is achieved in hydraulic systems by metering the flow of a fluid into or out of a constrained volume . Pressure control is achieved in hydraulic systems by metering the flow of a fluid into or out of a constrained volume. Relief valves and pressure-reducing valves are not pressure controllers.
What are the 5 basic components of a hydraulic system?
- Reservoir. ...
- Filters. ...
- Shut Off Valves. ...
- Control Valves. ...
- Pressure Relief Valve. ...
- Hydraulic Fuses. ...
- Accumulators.
How is force in a hydraulic system calculated?
The amount of force a hydraulic cylinder can generate is equal to the hydraulic pressure times the effective area of the cylinder. (Effective Area is the surface area of the piston face in square inches.) FORMULAS: Force = psi x Area of Piston .
What is hydraulic formula?
Pressure, Force and Horsepower Relationships: Pressure (psi) = force (lbs) / area (in2) Force (lbs) = area (in2) x pressure (psi) Area (in2) = force (lbs) / pressure (psi)
What are some examples of hydraulic systems?

- Hydraulic Brakes. Braking system of the vehicle is an important example of hydraulics. ...
- Hydraulic Steering. ...
- Hydraulic Jacks. ...
- Heavy Equipment. ...

- Hydraulic Shock Absorbers.
How harmful is hydraulic fluid?
HIGHLIGHTS: Exposure to hydraulic fluids occurs mainly in the workplace. Drinking certain types of hydraulic fluids can cause death in humans , and swallowing or inhaling certain types of hydraulic fluids has caused nerve damage in animals. Contact with some types of hydraulic fluids can irritate your skin or eyes.
What happens if you get injected with hydraulic fluid?
Hydraulic fluid or fuel entering the bloodstream can quickly result in death since the human body has no defence against it. If that weren’t serious enough, bacteria can be driven deeply into the wound causing dangerous infections.
Does a hydraulic pump create pressure?
A pump produces liquid movement or flow: it does not generate pressure . It produces the flow necessary for the development of pressure which is a function of resistance to fluid flow in the system. For example, the pressure of the fluid at the pump outlet is zero for a pump not connected to a system (load).
What is hydraulic pressure in simple words?
The total thrust, expressed in pounds or tons, that the hydraulic-feed mechanism on a drill can impose on a drill string; also, the pressure of the fluid within the hydraulic cylinders, generally expressed in pounds per square inch .
How much pressure is in a hydraulic return line?
The four basic line types in a hydraulic system are pump suction, return (Low pressure <100 PSI) , medium pressure (500 to 2000 PSI), and high pressure (2100 to 5000 PSI). Under-sizing fluid lines will result in high pressure loss and system overheating. Over sizing lines increases the cost of the system.
What liquid is used in hydraulics?
Three common varieties of hydraulic fluids found on the market today are petroleum-based, water-based and synthetics . Petroleum-based or mineral-based fluids are the most widely used fluids today. These fluids offer a low-cost, high quality, readily available selection.
