Hydraulic intensifiers are attachments to hydraulic machines that boost the pressure they can produce. The mechanism that applies pressure to the internal fluid is operated by two pistons of approximately equal size. The energy of a substantial volume of liquid at low pressure propels the device. A pump cannot supply the high pressure needed by some hydraulic equipment to function. Hydraulic rams, hydraulic presses, hydraulic lifts, and other related tools are examples of hydraulic machines. These machines require high pressure to operate. Typically, hydraulic intensifiers are put on operational equipment like pumps.

Hydraulic Intensifier in Details

The three major components of a hydraulic intensifier are linked in the proper sequence to enhance the input fluid’s pressure. They include fixed rams, sliding cylinders, and fixed cylinders.

• FIXED CYLINDER: The casing of the hydraulic intensifier. From the main supply, low-pressure liquid enters this area. Within the stationary cylinder, the ram or sliding cylinder moves.
• The sliding cylinder or ram is the second and middle part of the hydraulic intensifier. It alternately switches between the fixed ram and fixed cylinder. It merely has the ram as its single moving component. It slides as a result of the hydraulic pressure. The stationary ram delivers high pressure liquid to the sliding cylinder.
• The smallest and most inner part of the hydraulic intensifier is called FIXED RAM. The sliding cylinder is positioned all around it. A high-pressure fluid is used to feed this stationary ram.
• VALVE: There are four valves on the hydraulic booster as well. Please refer to them as A, B, C, and D for clarity. Low-pressure liquid can flow from the power source to the device thanks to “A” and “D.” By way of valve “D,” the liquid enters the stationary cylinder, travels via valve “A,” and then enters the sliding cylinder. By allowing low pressure fluid to exit the stationary cylinder and be emptied for deflation, the valve lessens fatigue. High-pressure fluid is directed toward the intensifier’s outlet, which is connected to the hydraulic engine, through valve “B.”
• how a hydraulic booster works
• As we all know, hydraulic boosters are used to intensify fluid pressure. The movement of the fluid inside the hydraulic booster is essential to its functionality
• The shift cylinder is initially stationary or at the lowest position. The “D” valve is then used to correctly fill the stationary cylinder with the low-pressure liquid. Next, the valves C, B, and D are shut off. The only open valve is valve “A,” allowing low-pressure liquids to enter the
• The cylinder or slide A low-pressure fluid can then flow from the stationary cylinder and vent to the exhaust pipe when valve “C” opens. The slide cylinder rises after the low pressure has left the stationary cylinder due to the supply from valve “A.” When it reaches the top position, the boost cylinder is filled with liquid under low pressure. Both “A” and “C” are closed once the sliding cylinder is fully filled with low pressure liquid. The low pressure fluid flowing through valve “D” enters the stationary cylinder and forces the valves “B” and “D” to open.
• In a solid cylinder, the high pressure liquid is created and fed to the necessary outlet or hydraulic equipment. Next, the valve lets the high-pressure fluid out.
• Use of hydraulic boosters
• Hydraulic boosters are utilised when incredibly high pressure is necessary.
• This device is employed when the pump is unable to deliver the requisite high pressure intensity on its own.
• In applications where a high pressure intensity is necessary to lift the weight, such as hydraulic hoists, hydraulic winches, hydraulic presses, and hydraulic elevators, hydraulic boosters are frequently utilised.
