Working principal of Hydraulic Intensifier

 Hydraulic Intensifier:- 

The hydraulic Intensifier is a device that is used for increasing the intensifier of the pressure of water when water is available in large quantity but at low pressure. This device has to be used when a certain hydraulic machine has to be supplied water at high pressure but the water from the supply source does not possess the high intensity of pressure. Its function is analogue to step-up transform as used in the transmission of power.


An intensifier consists of a fixed cylinder that surrounded a sliding cylinder. The sliding cylinder further surrounded a fixed ram which has a central hole in it. initially, consider the sliding cylinder at the bottom of the stroke, and the fixed cylinder is full of low-pressure water. The valves V2 and V4 are closed at this portion. Now, valve V1 is opened to admit low-pressure water in the sliding cylinder. Similarly, valve V3 is also opened which permitted the low-pressure water inside the fixed cylinder to pass bout from the fixed cylinder through the exhaust outlet when the sliding cylinder starts lifting up inside the fixed cylinder. When the sliding cylinder reaches its topmost position, then the inside of the sliding cylinder is full of low-pressure water. The valves V1 and V2 are than closed and valves V2 and V4 are opened. The low-pressure water starts now entering the fixed cylinder to move downward, thereby producing high pressure inside the sliding cylinder. This high-pressure water from the sliding cylinder is then given to the machine from valve V2. In case A1 and A2 are cross-section areas of the fixed and sliding cylinders, then,.......

P1 A1 = P2 A2

or,   P2 = P1 x A1 / A2                                 [A1 > A2, hence P2 > P1]

The working Principle of the Hydraulic Crane

Image
 Hydraulic Crane:- A hydraulic crane consists of a central pedestal supporting a mast from which is attached a jib or ram. The jib can be raised or lowered to reduce or increase the radius of action of the crane. The mast can revolve about the vertical axis so that jib with load can be positioned anywhere in a circular area around the crane . Thus, both by lowering or raising the jib revolving around the pedestal,  the load can be moved to any place within the crane area action. there are two sets of pulleys include one which is stationary and the other which is moveable. The load is suspended by a wire rope that passes over a guide pulley fixed on the jib and on another end the wire rope is attached to the hydraulic jigger. The jigger consists of a fixed pulley. at the bottom end of the fixed cylinder is attached to a movable pulley. At the bottom end of the fixed cylinder is attached to a fixed pulley. The jigger is attached to the mast. The wire rope to the jigger passes ov...

Bernoulli's Equation In Irrotational Flow

Image
  Bernoulli's Equation In Irrotational Flow we have obtained Bernoulli’s equation       This equation was obtained by integrating the Euler’s equation (the equation of motion) with respect to a displacement ' ds'  along a streamline. Thus, the value of C in the above equation is constant only along a streamline and should essentially vary from streamline to streamline. The equation can be used to define relation between flow variables at point B on the streamline and at point A, along the same streamline. So, in order to apply this equation, one should have knowledge of velocity field beforehand. This is one of the limitations of application of Bernoulli's equation. Irrotationality of flow field Under some special condition, the constant C becomes invariant from streamline to streamline and the Bernoulli’s equation is applicable with same value of C to the entire flow field.  The typical condition is the irrotationality of flow field. Proof: Let u...

The Pelton wheel is an impulse turbine

Pelton wheel  The  Pelton wheel is an impulse turbine. In the Pelton wheel, the pressure energy of water is fully converted into kinetic energy by passing water through the nozzle. This forms a high-velocity jet that is used for the driving wheel by changing its velocity on the buckets. A Pelton turbine consists of a rotor. On the periphery of the rotor are mounted equally spaced buckets that have either double hemispherical or double ellipsoidal shapes. Water is brought down from a high head source like a dam through a pipe system, Which is called a penstock. A nozzle is provided at the end of the penstock which converts the potential energy of high head water into a high-velocity water jet. The high-velocity water jet emerging from the nozzle impinges on the buckets of the Pelton wheel and it sets the wheel in Function of the casing of a Pelton turbine is.....  (i) to prevent the splashing of water;   (ii) to discharge water to tail race; and  (iii) to safegu...
