What is rigid coupling

 What is rigid coupling? Rigid coupling Rigid coupling is used only whenever the misalignment between equipment shafts is very less or no misalignment is present in the system. When the equipment is appropriate to carry the reactionary load produced from trying to flex rigid couplings. This type of coupling mostly prefers for vertical applications such …

Types of valve

Types of Valve Valves are mechanical devices that control the flow of fluids (liquids, gases, or slurries) by opening, closing, or partially obstructing passageways. There are various types of valves designed for different applications, and they are categorized based on their function, design, and the industry they serve. Additionally, valves are subject to various codes …

Basics introduction of bearing

Bearing The term bearing comes from the bear, a bearing is a component that supports load while permitting relative motion between two parts of the machine. Bearing is an important part of a machine that carries the load, reduces friction, and gives a smooth operation. The selection of bearings is based on the requirement of …

Cavitation in centrifugal pump

Compressure image

Cavitation in the centrifugal pump Cavitation in centrifugal pump is the formation of bubbles, because the liquid suction pressure fall below its vapor pressure or any other reasons. There are many cases of cavitation in centrifugal pumps, these are discussed below. The formation of the bubble mostly happens in a pipe inside, equipment, valves, and …

NPSH (Net positive suction head)

NPSH (Net positive suction head)  What is NPSH? NPSH (net positive suction head) is the difference between suction pressure and lowest pressure inside the pump or system. By the use of the Bernoulli theorem, calculated if the suction pressure is greater than vapor pressure, then the risk of cavitation is negligible, but in other cases, …
