Liebherr Interview Questions, Process, and Tips for Experienced

A variable axial piston pump is a type of hydraulic pump that uses a rotating cylinder block with pistons to generate fluid flow.

• The pump consists of a cylinder block with multiple pistons arranged in a circular pattern.

• As the cylinder block rotates, the pistons move in and out of their respective cylinder bores.

• The movement of the pistons creates a reciprocating motion, which draws in and pushes out hydraulic fluid.

The speed difference in a hydraulic ram is due to the difference in effective areas on the head side and rod side.

• The head side of the ram has a larger effective area, resulting in slower speed.

• The rod side of the ram has a smaller effective area, resulting in faster speed.

• This speed difference is a result of the hydraulic pressure acting on different areas.

• The speed ratio between the head side and rod side can be calc...read more

A pressure relief valve is used to protect equipment and systems from excessive pressure by releasing the pressure when it exceeds a certain limit.

• Prevents damage to equipment and systems

• Ensures safety of personnel

• Maintains system integrity

• Prevents explosions or ruptures

• Relieves excess pressure by opening and releasing fluid or gas

• Commonly used in boilers, pressure vessels, pipelines, and hydraulic systems

An orifice is a small opening or hole through which fluid or gas can flow.

• Orifices are commonly used in various industries, such as plumbing, engineering, and manufacturing.

• They are often used to control the flow rate of fluids or gases.

• Orifices can be found in devices like nozzles, valves, and flow meters.

• The size of an orifice determines the flow rate and pressure drop across it.

• Examples of orifices include the tiny ...read more
