GERAB INDIA ENGINEERING PRODUCTS Design Engineer Interview Questions and Answers

Wear travel refers to the movement of material due to friction and wear.

• It is the displacement of material caused by frictional forces.

• It can lead to surface damage and changes in the shape of the material.

• Examples include the wear of tires on a road surface or the erosion of a metal component due to repeated use.

• Wear travel is an important consideration in the design and maintenance of mechanical systems.

Design process is a systematic approach to problem-solving and creating solutions through research, ideation, prototyping, and testing.

• Identify the problem or need

• Conduct research and gather information

• Brainstorm and ideate potential solutions

• Create prototypes and test them

• Refine and iterate on the design

• Implement and launch the final solution

Gate valves can have trims made of various materials depending on the application.

• Trims can be made of materials such as stainless steel, bronze, or brass.

• The choice of trim material depends on factors such as the fluid being handled and the temperature and pressure of the system.

• Harder materials like stainless steel are often used for high-pressure applications.

• Soft materials like bronze or brass are used for low-pres...read more

API 6D latest edition has several changes.

• The latest edition includes new definitions and terminology.

• It also has updated requirements for testing and inspection.

• There are changes in the design and materials requirements as well.

• The latest edition also includes new requirements for valve marking and documentation.

The max dia of handwheel depends on the application and the force required to operate it.

• The max dia of handwheel is determined by the torque required to operate it.

• Larger handwheels provide greater leverage and require less force to operate.

• The max dia of handwheel can range from a few inches to several feet depending on the application.

• Factors such as space constraints, ergonomics, and aesthetics may also influence t...read more

Gearbox selection depends on application requirements such as torque, speed, and power.

• Determine the required torque, speed, and power for the application

• Select a gearbox with a suitable gear ratio to meet the requirements

• Consider factors such as efficiency, noise, and cost

• Choose a gearbox with a suitable mounting and shaft configuration

• Examples: planetary gearbox for high torque, worm gearbox for low speed

Bolting calculation involves determining the appropriate size, type, and number of bolts needed to securely fasten two or more objects together.

• Consider the material and thickness of the objects being fastened

• Determine the required clamping force

• Select the appropriate bolt size and type

• Calculate the number of bolts needed based on the required clamping force

• Consider factors such as corrosion resistance and installation...read more
