Lupin Shift Incharge Interview Questions and Answers

Delta P refers to the difference in pressure between two points in a system.

• Delta P is commonly used in fluid dynamics to measure pressure differences.

• It is calculated by subtracting the pressure at one point from the pressure at another point.

• Delta P is important in industries like manufacturing and HVAC for maintaining proper pressure levels.

• For example, in a piping system, delta P can indicate if there is a blockage

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

• A chiller is used to cool down water or other fluids in industrial or commercial settings.

• There are two types of chillers: vapor-compression and absorption.

• Compressors are used in refrigeration systems to compres...read more

There are several types of pumps used in various industries.

• Centrifugal pumps

• Positive displacement pumps

• Axial flow pumps

• Mixed flow pumps

• Jet pumps

• Submersible pumps

• Diaphragm pumps

• Gear pumps

• Peristaltic pumps

• Rotary lobe pumps

• Screw pumps

• Vane pumps

The pump parts can differ in terms of material, size, shape, and function.

• Different pumps may have different impellers, casings, shafts, bearings, and seals.

• The material used for the parts can vary depending on the type of fluid being pumped and the environment.

• The size and shape of the parts can also vary depending on the flow rate and pressure requirements.

• The function of the parts can differ based on the type of pum...read more

Solenoid valve works on the principle of electromagnetism to control the flow of fluids or gases.

• It consists of a coil, plunger, and valve body

• When the coil is energized, it creates a magnetic field that pulls the plunger towards it

• This movement opens or closes the valve, allowing or blocking the flow of fluid or gas

• Used in various applications such as refrigeration, HVAC systems, and industrial automation
