A floor jack is a device used to lift heavy objects from the ground. The floor jack uses the Pascal principle which bases its argument on the fact that when a pressure is exerted at a given point of the hydraulic fluid, the same pressure gets transferred to the other end of the enclosed fluid. Some heavy objects like cars can only be lifted above the ground by the floor jacks. The floor jack in itself consists of the following parts: Please feel free to read more about this at this site
The reservoir is the bulkiest part of the floor jack. It holds the hydraulic fluid into place. It is this fluid which transfers the exerted pressure to other parts of the jack so that it can operate. In essence, the fluid must be full in the reservoir so that the pressure inserted at one point cannot be altered.
This is another basic part of the floor jack. It basically pulls the hydraulic fluid from the reservoir to the main cylinder through the check valve. Without the pump, the floor jack may not be effective. It only works by means of pressure. It is the pump which provides this pressure. The pressure being transferred to the cylinder depends on the presser which is exerted at the point of the pump.
3. Check valve
The check valve acts as the door for the transfer of pressure from the reservoir to the main cylinder in the form of fluid. Basically, it is small in size so that it can enable the fluid being transferred to flow at a higher pressure that it was at the reservoir. The smaller the circumference of the valve, the higher the energy being transferred.
4. Main cylinder
This holds the ram piston into place. It is the ram piston which gets forced out when pressure is exerted so that pressure is released which can trigger the floor jack to lift an object without much strain. The main cylinder is connected to the release valve so that it can allow the ram piston to retract when pressure is exerted to it.
5. Ram piston
This last part meets the object to be lifted. It is made up of strong metals so that it does not get destroyed when pushing up a heavy object. As much as it comes with lots of pressure, the pressure can be rendered useless especially when the object being lifted is heavy hence destroying the component of a floor jack is the ram piston. It is the last point where pressure which is exerted to the jack.
Any floor jack cannot work effectively if any of the described parts above is faulty or is missing. The parts must, however, be made from strong materials. With an effective floor jack, you will not struggle in using your own energy to lift objects. The manual or physical lifting of the objects may not be effective especially in a garage environment where an object like a car has to be lifted and maintained at that position for repair. His means that every part of the floor jack is important and as a user, you got to know them for the effectiveness in operation.
