Applications of Hydraulic Intensifier

Nowadays, hydraulic intensifiers have become a prevalent choice in hydraulic power packs, offering an economical solution to generate high pressure without needing an expensive dedicated high-pressure system. They find utility when conventional siphon mechanisms fail to deliver the desired force and pressure as per the demands.

What is A Hydraulic Intensifier?

An intensifier or pressure booster is an internal power regenerator device used to increase fluid pressure, usually oil or water. Intensifiers may be either hydraulically or pneumatically operated, the advantage of the latter being that no power unit is required since the air can be taken from the general supply or storage tank. This hydraulic machine increases the intensity of pressure of a given liquid with the help of hydraulic energy of low-pressure liquid of large quantities. Such a device is needed when hydraulic machines such as hydraulic press require water at very high pressure, which cannot be obtained from the main supply directly. By means of an intensifier, it is possible to raise the intensity of pressure as high as 160 MN/m²

Volute pump

Volute pumps and turbine pumps are types of centrifugal pumps according to the type of casing provided. They have different designs and operating principles. A volute pump has a volute-shaped housing that surrounds the impeller. The liquid enters the pump and is directed to the impeller, where the centrifugal force accelerates it. The liquid then exits the impeller and flows into the volute-shaped housing, where it is directed to the outlet. Volute helps to direct the fluid and reduce the velocity, thus increasing the pressure of the fluid. A volute pump's performance can be improved by providing an annular space called a vortex chamber between the impeller and the volute casing.

What does priming of a centrifugal pump mean?

Priming of a pump refers to the process of filling the pump and piping system with liquid before starting the pump. The main purpose of priming is to eliminate any air pockets or vapour that may be present in the pump's casing, suction piping and a portion of delivery pipe up to delivery valve so that liquid is continuously in contact with the pump impeller. When the impeller is rotated, it can impart angular momentum to the filled liquid, creating a necessary pressure difference between the inlet and outlet of the pump, thus allowing liquid to be lifted. If a centrifugal pump is not primed before starting, air pockets inside the impeller cause vortices and result in flow discontinuity.

Pump and Turbine

Pumps and turbines are mechanical devices that transfer energy, but they work in opposite ways. A pump is a mechanical device that moves fluids, such as liquids or gases, from one place to another. It increases the pressure of the fluid, which causes it to flow through a pipe or other conduit.

Here is the comparison between the magnetic drive pump and the canned motor pump.

What is a canned motor pump?

Canned pumps are sealless pumps. One of the notable features of the canned motor pump is the integral construction of pump-motor and the absence of a shaft seal. As shown in the above figure, it is a close-coupled unit in which the motor housing cavity and pump casing are interconnected. The motor, pump shaft and bearings operate wet inside the pumped liquid. Hence the hazardous or toxic liquid is confined within this containment shell.

What is a sealless pump? What is their importance?

Some pump applications require zero product leakage, even less than the minimal leakage possible from a well-chosen and well-maintained mechanical seal. Zero leakage is essential while handling toxic liquid. Most emissions are caused by leakages in pumps used in the industry. A number of stringent environmental and safety regulations force the industry to adopt methods that reduce or eliminate fugitive emissions in the workplace.
