Indian Oil Corporation Pump Operator Interview Questions and Answers
6 Interview questions
A pump is used to move fluids, while a compressor is used to increase the pressure of gases.
Pump is used for fluids, compressor is used for gases
Pump moves fluids from one place to another, compressor increases the pressure of gases
Pump operates at lower pressures, compressor operates at higher pressures
Examples: Water pump, fuel pump, air compressor
Centrifugal pumps are named so because they use centrifugal force to generate pressure and move fluid.
Centrifugal pumps work by converting rotational kinetic energy into hydrodynamic energy.
The pump's impeller spins rapidly, creating a centrifugal force that pushes the fluid towards the outer edges of the impeller.
This centrifugal force increases the fluid's velocity and pressure, allowing it to be discharged thro...
Pumps are used for water to facilitate its movement from one place to another.
Pumps are used to extract water from wells, rivers, or other sources for various purposes like irrigation, drinking water supply, or firefighting.
They are also used in industries to transfer water for cooling systems, manufacturing processes, or wastewater treatment.
Pumps are essential in construction projects for dewatering excavations ...
There are various types of pumps used for different purposes, such as centrifugal pumps, reciprocating pumps, and diaphragm pumps.
Centrifugal pumps are commonly used in industries for transferring fluids.
Reciprocating pumps are used in applications where high pressure is required, such as in hydraulic systems.
Diaphragm pumps are often used for pumping fluids with high viscosity or containing solids.
Other types of ...
Reciprocating pumps are used in high head applications due to their ability to generate high pressure.
Reciprocating pumps have a piston or plunger that moves back and forth to create pressure.
They are capable of generating high discharge pressures, making them suitable for high head applications.
The reciprocating action allows for better control and regulation of flow rate.
They are commonly used in industries such...
Petrol and diesel have different densities.
Petrol has a lower density than diesel.
The density of petrol is around 0.71 to 0.77 grams per cubic centimeter.
The density of diesel is around 0.82 to 0.85 grams per cubic centimeter.
Density is a measure of mass per unit volume.
