Tata Steel Mechanical Supervisor Interview Questions, Process, and Tips

Q1. What is piston pump
Ans. 
A piston pump is a type of positive displacement pump that uses a piston to move fluid through a system.
• Piston pumps are commonly used in hydraulic systems to generate high pressure for various applications.

• They operate by using a reciprocating piston to create a vacuum at the inlet and push fluid out through the outlet.

• Examples of piston pumps include axial piston pumps, radial piston pumps, and duplex piston pumps.

Q3. What is coupling
Ans. 
Coupling is a device used to connect two shafts together at their ends for transmitting power.
• Couplings are used to transmit power from one shaft to another without misalignment.

• They are designed to accommodate slight misalignments and allow for easy disconnection.

• Common types of couplings include rigid, flexible, and fluid couplings.

• Examples of couplings include gear couplings, grid couplings, and jaw couplings.

Q4. Vernier caliper list count
Ans. 
Vernier caliper is a precision measuring tool used to measure dimensions with high accuracy.
• Vernier calipers have a main scale and a sliding Vernier scale for more precise measurements.

• The count on a Vernier caliper refers to the number of divisions on the Vernier scale that align with divisions on the main scale.

• The count can vary depending on the precision of the caliper, with common counts being 10, 20, or 50 divisi
