There are various types of gearboxes used in maintenance fitting, including spur gearboxes, helical gearboxes, bevel gearboxes, and worm gearboxes.
Spur gearboxes have straight teeth and are commonly used in applications with low to moderate speeds and loads.
Helical gearboxes have angled teeth and provide smoother and quieter operation compared to spur gearboxes.
Bevel gearboxes are used to transmit power between shafts ...
Pitch is the distance between two adjacent threads in a screw or bolt.
Pitch is measured in millimeters or inches.
It determines the tightness of the screw or bolt.
Different types of pitch include coarse, fine, and extra fine.
Pitch is important in alignment as it affects the positioning of rotating machinery.
Misaligned pitch can cause vibration, noise, and premature wear and tear.
Misalignment is when two or more parts are not properly aligned. Backless refers to a type of shoe without a back.
Misalignment can cause wear and tear on machinery and decrease efficiency.
Examples of misalignment include a crooked belt on a conveyor or a misaligned shaft in a motor.
Backless shoes are typically sandals or slip-ons that do not have a heel or back portion.
Backless shoes can be more comfortable in hot weat

Quantitative aptitude, Reasoning
Centrifugal pumps use impellers to move fluid while reciprocating pumps use pistons or diaphragms.
Centrifugal pumps are more commonly used for high flow rate and low viscosity fluids while reciprocating pumps are used for low flow rate and high viscosity fluids.
Centrifugal pumps are generally less expensive and require less maintenance than reciprocating pumps.
Reciprocating pumps are better suited for applications wher...

Pressure and velocity compounding are methods used to increase the efficiency of steam turbines.
Pressure compounding involves dividing the pressure drop across the turbine into smaller stages, each with its own set of moving blades.
Velocity compounding involves dividing the steam flow into smaller streams, each flowing through a set of fixed blades.
Both methods increase the efficiency of the turbine by reducing the amo...
Iron-iron carbide diagram is a graphical representation of the phases of iron and carbon at different temperatures and compositions.
Also known as the Fe-C diagram
Shows the transformation of iron from ferrite to austenite to pearlite
Used to determine the microstructure and properties of steel
Helps in designing heat treatment processes for steel
Important tool for metallurgists and materials engineers
Normalizing, annealing, and hardening are heat treatment processes used to alter the properties of metals.
Normalizing involves heating the metal to a temperature above its critical point and then cooling it in air. This process improves the strength and toughness of the metal.
Annealing involves heating the metal to a specific temperature and then cooling it slowly. This process reduces the hardness and increases the du...
Efficiency of Rankine cycle formula.
Efficiency = (Net work output / Heat input)
Efficiency = (1 - T2/T1)
T1 is the temperature of steam at the inlet of turbine
T2 is the temperature of steam at the outlet of turbine
Net work output = (P1 - P2) * (V2 - V1)
Heat input = m * (h1 - h2)
m is the mass flow rate of steam
h1 is the enthalpy of steam at the inlet of turbine
h2 is the enthalpy of steam at the outlet of turbine
I applied via Walk-in and was interviewed before Sep 2020. There was 1 interview round.
