The PA9 hydraulic pump is capable of operating a range of hydraulic cylinders, including large 100 ton units, however the PitBull™ Stone Chiseler only uses a small bore 5 ton piston. The air supply only needs enough volume to be able to keep the air pressure up at the rate you wish to work. Harder stone will need more tonnage (more psi) to

The connection between the circulatory system and hydraulics is; hydraulics are the science of conveyance of fluids under pressure and are also concerned with absorbing shock and keeping everything smooth and steady. The circulatory system too is very similar. The heart acts like pump and sends/takes blood through the vessels.

as hydraulic systems. The hydraulic system works on the principle of Pascal’s law which says that the pressure in an enclosed fluid is uniform in all the directions. The Pascal’s law is illustrated in figure 5.1.1.The force given by fluid is given by the multiplication of pressure and area of cross section.

A sheared pump coupling is an obvious cause of failure, however the location of some pumps within hydraulic systems makes this difficult to check so it may go overlooked. 6. CHECK YOUR PUMP RELIEF VALVE. It is possible that the entire flow could be passing over the relief valve, preventing the pressure from developing.

If the stack was a thin-wall vertical tube in the sun, then heating the column of air would reduce it''s density, so the warmer air would be more buoyant and tend to rise. If the energy was extracted at the bottom of the stack, the pressure difference would be limited to less than the 14.5 psi of atmospheric pressure.

By controlling the fluid pressure we can reduce the damage to a greater extent. But, one of the major advantages of hydraulics is speed and if the fluid pressure is reduced in order to control the speed of the piston rod, then the entire system will move towards failure, or the required performance will not be obtained.

A hydraulic accumulator is used for one of two purposes: either to add volume to the system at a very fast rate or to absorb shock. Which function it will perform depends upon its pre-charge. If the accumulator is to be used to add volume to the system, its pre-charge must be somewhat below the maximum system pressure so oil can enter it.
