VBC Ferro Alloys Assistant Engineer Mechanical Interview Questions, Process, and Tips

Hydraulics is a branch of engineering that deals with the mechanical properties of liquids, especially water or oil, and their applications.

• Hydraulics involves the study of fluid mechanics and the behavior of liquids under pressure.

• It is used in various applications such as hydraulic machinery, hydraulic systems, and hydraulic power transmission.

• Hydraulic systems use fluid pressure to generate, control, and transmit po...read more

Control valves are used to regulate the flow, pressure, temperature, or level of a fluid in a system.

• There are several types of control valves, including globe valves, butterfly valves, ball valves, and plug valves.

• Globe valves are commonly used for throttling and regulating flow.

• Butterfly valves are often used for large flow rates and low-pressure applications.

• Ball valves provide quick shut-off and are suitable for on...read more

Helical gearboxes are commonly used in the steel industry.

• Helical gearboxes are preferred in the steel industry due to their high efficiency and smooth operation.

• These gearboxes provide better load distribution and reduce noise and vibration.

• They are capable of handling heavy loads and high torque requirements.

• Helical gearboxes are commonly used in steel rolling mills, steel processing plants, and other steel manufactu

Check in bearing is a type of bearing that allows axial movement while preventing radial movement.

• Check in bearing is designed to accommodate axial loads.

• It allows movement in one direction while preventing movement in the opposite direction.

• This type of bearing is commonly used in applications where axial displacement is required, such as in automotive suspensions.

• An example of a check in bearing is a thrust bearing u

Servo valve nas value refers to the National Aerospace Standard (NAS) specification for servo valves.

• NAS value is a standard that defines the performance and quality requirements for servo valves used in aerospace applications.

• It ensures that servo valves meet specific criteria for reliability, accuracy, and durability.

• NAS value is often used as a reference when selecting or evaluating servo valves for aerospace system...read more

Ring granulator crusher is a machine used to crush coal, minerals, and other materials.

• Ring granulator crushers are used in coal handling plants to crush coal and other materials.

• They consist of a rotor with crushing elements inside a steel cage.

• The drive unit of these crushers includes a gearbox, motor, and coupling.

• The gearbox is used to reduce the speed of the motor and increase the torque.

• The motor provides the pow...read more

Bearings are of various types such as ball, roller, plain, etc. Furnace maintenance includes cleaning, inspection, and replacement of parts.

• Different types of bearings are used in mechanical systems depending on the load and speed requirements.

• Ball bearings are commonly used in high-speed applications while roller bearings are used in heavy load applications.

• Plain bearings are used in low-speed and high-load applicatio...read more
