Arise Shine Exports & Imports Interview Questions and Answers

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 the size of the handwheel.

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-pressure applications to prevent damage to the valve seat.

• Some...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

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.
