10+ Venpa Global Technologies Interview Questions and Answers
Q1. Why hydraulics Ram has different speed in head side and rod Side?
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 calculated using the effective areas.
Example: If the head side...read more
Q2. Explain about open loop & close loop operation in hydraulic system.
Open loop and closed loop are two modes of operation in hydraulic systems.
Open loop operation: The hydraulic system operates without feedback control. The output is not adjusted based on the system's performance.
Closed loop operation: The hydraulic system uses feedback control to adjust the output based on the system's performance.
Open loop systems are simpler and less expensive, but they lack precision and accuracy.
Closed loop systems are more complex and costly, but they of...read more
Q3. What is the purpose of pressure relief valve?
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
Q4. What is tappet setting required in engines ?
Tappet setting is the process of adjusting the clearance between the tappet and the valve stem in an engine.
Tappet setting ensures proper valve timing and prevents engine damage.
It involves adjusting the clearance between the tappet and the valve stem using a feeler gauge.
The correct tappet setting varies depending on the engine model and manufacturer.
Incorrect tappet setting can cause engine noise, poor performance, and even engine failure.
Regular tappet setting maintenance ...read more
Q5. Draw a basic Hydraulic circuit and expain ?
A hydraulic circuit is a system that uses pressurized fluid to transmit power.
A hydraulic pump is used to create pressure in the fluid.
Valves control the flow of fluid through the circuit.
Actuators, such as cylinders or motors, convert the fluid pressure into mechanical force.
A reservoir stores the fluid and a filter removes contaminants.
Examples include excavators, cranes, and hydraulic presses.
Q6. What is your core values ?
My core values include integrity, accountability, and continuous learning.
Integrity: I believe in always doing the right thing, even when no one is watching.
Accountability: I take ownership of my actions and responsibilities.
Continuous learning: I strive to constantly improve my skills and knowledge.
Example: I once discovered a mistake in a project I was working on, and instead of ignoring it, I took responsibility and rectified the error.
Example: I regularly attend workshops...read more
Q7. What is orifice?
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 hole in a spray bottle nozzle or the opening in a fuel inj...read more
Q8. Explain about Starting circuit.
The starting circuit is responsible for initiating the engine's operation.
The starting circuit consists of components such as the battery, starter motor, ignition switch, and solenoid.
When the ignition switch is turned on, it sends a signal to the solenoid, which then engages the starter motor.
The starter motor uses electrical energy from the battery to turn the engine's crankshaft, starting the combustion process.
Once the engine starts running, the starter motor disengages f...read more
Q9. What are the grades of Hardwares like Screw, nut washer
Hardware grades are typically classified based on material composition, strength, and corrosion resistance.
Hardware grades are often denoted by a combination of letters and numbers, such as Grade 8.8 or Grade 316.
Higher grade numbers generally indicate a higher tensile strength or corrosion resistance.
Common grades for screws include Grade 2, Grade 5, and Grade 8, with Grade 8 being the strongest.
For nuts and washers, common grades include Grade 2, Grade 5, and Grade 8, with ...read more
Q10. Variable axial piston pump how works
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 displacement of the pump can be adjusted by changing the...read more
Q11. What is the material for wheel, Pin
The material for wheel is typically rubber or plastic, while the material for pin is usually metal such as steel or aluminum.
Wheel material is commonly rubber or plastic for flexibility and durability
Pin material is usually metal like steel or aluminum for strength and stability
Q12. What means the General tolerances
General tolerances refer to the acceptable range of variation in dimensions or properties of a part or product.
General tolerances are typically specified in engineering drawings to ensure parts fit and function properly.
They are usually expressed as a range of acceptable values, such as +/- 0.1mm.
Tolerances can vary depending on the specific requirements of the part or product.
Examples of general tolerances include dimensional tolerances for machined parts or material propert...read more
Q13. How to calculate motor power
Motor power can be calculated using the formula: Power (W) = Torque (Nm) x Speed (RPM) / 9.548
Calculate the torque required for the application
Determine the speed at which the motor will operate
Use the formula Power (W) = Torque (Nm) x Speed (RPM) / 9.548 to calculate motor power
Q14. How welds are considered
Welds are critical in design engineering for joining metal components together.
Welds must be strong enough to withstand the intended load and stress.
Proper welding techniques and materials must be used to ensure the integrity of the weld.
Inspections and testing should be conducted to verify the quality of the weld.
Consideration should be given to factors such as joint design, welding process, and material compatibility.
Examples of weld considerations include fillet welds, gro...read more
