I applied via Walk-in and was interviewed in Sep 2022. There were 2 interview rounds.
A lathe is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, drilling, knurling, or deformation.
Lathe is used to shape and cut materials such as wood, metal, and plastic.
It rotates the workpiece on its axis and a cutting tool is applied to the workpiece to remove material.
Lathe can perform various operations such as turning, facing, drilling, borin...
Boiler drum is a cylindrical container which is used to store water and steam produced in a boiler.
It is a vital component of a boiler system.
It is usually made of steel and is located at the top of the boiler.
It acts as a reservoir of water/steam and helps to separate steam from water.
It also helps to regulate the pressure and temperature of the steam.
The level of water in the drum is maintained by a feedwater control...
I applied via Referral and was interviewed before Aug 2022. There were 2 interview rounds.
Types of gear boxes and gears commonly used in mechanical engineering include spur gears, helical gears, bevel gears, and worm gears.
Spur gears: most common type, straight teeth parallel to the gear axis
Helical gears: angled teeth for smoother and quieter operation
Bevel gears: used to change the direction of rotation
Worm gears: used for high reduction ratios and high torque applications
Types of conveyors include belt, roller, chain, screw, and pneumatic. Maintenance involves regular inspection, cleaning, lubrication, and replacing worn parts.
Types of conveyors: belt, roller, chain, screw, pneumatic
Maintenance tasks: regular inspection, cleaning, lubrication, replacing worn parts
Examples: Belt conveyor used in manufacturing plants, roller conveyor in warehouses
Troubleshooting blowers and compressors involves identifying and resolving issues with their operation.
Start by checking for any unusual noises or vibrations coming from the blower or compressor.
Inspect the filters and ensure they are clean and not clogged, as this can affect performance.
Check for any leaks in the system, as this can lead to a decrease in efficiency.
Verify that all connections and components are secure...
Overhauling gear boxes and fans compressors involves disassembling, inspecting, repairing, and reassembling the components to ensure optimal performance.
Disassemble the gear boxes and fans compressors carefully to inspect for any wear or damage
Replace any worn out or damaged parts with new ones
Clean and lubricate all components before reassembling
Perform tests to ensure proper functioning after overhaul

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. An AHU (Air Handling Unit) is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system.
Chillers are commonly used in commercial and industrial buildings to cool water or other fluids for air conditioning or process cooling.
AHUs are responsible for con...

Bernoulli theorem explains the relationship between fluid velocity, pressure, and elevation.
Bernoulli theorem states that as the velocity of a fluid increases, its pressure decreases.
It is based on the principle of conservation of energy in fluid flow.
The theorem is commonly used in fluid dynamics and aerodynamics.
It can be applied to various situations like flow through pipes, airfoils, and nozzles.
For example, when w...
AC and DC are two types of electrical current. AC changes direction periodically while DC flows in one direction.
AC stands for Alternating Current and DC stands for Direct Current.
AC changes direction periodically, typically at a frequency of 50 or 60 Hz.
DC flows in one direction continuously.
AC is used for power transmission over long distances.
DC is commonly used in batteries and electronic devices.
AC can be easily c...
