Tekman India Design Engineer Interview Questions, Process, and Tips

Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings use balls to reduce friction and support radial and axial loads.

• Roller bearings use cylindrical rollers to support heavy radial loads.

• Plain bearings have a sliding surface instead of balls or rollers.

• Fluid bearings use a thin layer of liquid or gas to support rotating shafts.

• Other types include magnetic bearings,

Types of pumps in engineering include centrifugal pumps, reciprocating pumps, and rotary pumps.

• Centrifugal pumps use a rotating impeller to increase the pressure of a fluid.

• Reciprocating pumps use a piston or diaphragm to displace the fluid.

• Rotary pumps use rotating mechanisms to move the fluid, such as gear pumps or screw pumps.

A pump is a mechanical device that moves fluids or gases by applying mechanical force.

• Pumps are used to transfer liquids in various industries such as water treatment, oil and gas, and manufacturing.

• They can be classified into different types based on their operation, such as centrifugal pumps, positive displacement pumps, and diaphragm pumps.

• Pumps play a crucial role in maintaining the flow of fluids in systems like H...read more

Vessel design involves understanding materials, pressure, safety, and functionality for various applications.

• Material Selection: Choose materials like stainless steel or composites based on corrosion resistance and strength.

• Pressure Considerations: Design must withstand internal and external pressures; for example, pressure vessels in chemical plants.

• Safety Factors: Incorporate safety margins to prevent failure; ASME c...read more

GD&T is a system for defining and communicating engineering tolerances using symbols and rules to ensure proper fit and function.

• Defines allowable variations in part geometry, ensuring parts fit together correctly.

• Uses symbols to represent features like flatness, parallelism, and concentricity.

• Example: A flatness tolerance ensures a surface is within a specified distance from a perfect plane.

• Helps in reducing manuf...read more
