Hydraulic presses can exert many thousands of pounds of force, making them useful for industrial operations such as forming metal parts. You typically measure hydraulic pressure in pounds per square inch (psi), which is force per unit area. To calculate the force produced, multiply the pressure ...
Where a traditional hydraulic ram uses the power of a pumped fluid to push the ram back and forth a limited distance, a hydraulic motor uses continuously flowing fluid to turn the shaft for as long as necessary. If you want to make the motor turn in the opposite direction, you simply ...
“Power Down, Spring Return” hydraulic jack systems use hydraulic pressure to extend the jacks (and lift/level the RV), but they use springs to supply the pressure to return the jacks to their retracted position. When the system calls for retracting the jack(s) it opens the hydraulic valve...
An engine hoist can lift several hundred pounds by simply moving a lever. The key component of a hoist is its hydraulic cylinder, where the motion of the lifting lever is transformed by a pump into fluid pressure. Since fluid can't be compressed, the pressure causes a piston inside the cy...
Like torque converters, wet multi-plate clutches use hydraulic pressure to drive the gears. The fluid does its work inside the clutch piston, seen in the diagram above. When the clutch is engaged, hydraulic pressure inside the piston forces a set of coil springs part, which pushes a series ...
When the rider operates one of the brakes, hydraulic pressure, acting through the brake line, causes the brake pads to squeeze against the disc on both sides. Friction causes the disc and the attached wheel to slow down or stop. Brake pads must be replaced periodically because the pad ...
Anyone that plans on handling some of their own car maintenance or repair will eventually need to use a hydraulic car jack. The fact that these tools will be lifting and holding thousands of pounds means it is important that anyone using a hydraulic car
It doesn’t take much for a winch line to turn into a dangerous projectile. Whether resulting from a failed recovery point, improper maintenance, or operator error, a steel or synthetic cable shearing under thousands of pounds of pressure can easily wreak havoc on anything in its path, whether...
Brake fluidis non-compressible in its normal liquid state – to ensure hydraulic pressure is transferred properly when you step on the brake pedal. Gases produced as a result of boiling make the fluid compress, causing a soft and spongy pedal feel and reduced braking performance. You don’t ...
become corroded by rust due to moisture,road salt, or regular wear and tear.Over time, rust can cause the development of small holes through which brake fluid can leak. Brake fluid loss leads to hydraulic pressure loss, which causes the brake pedal to feel low or soft and go to the ...
