10+ Concentrix Corporation Interview Questions and Answers
Q1. what are most common problem in hydraulic system
The most common problem in hydraulic systems is fluid contamination.
Fluid contamination
Leakage in hoses and fittings
Cavitation
Overheating
Wear and tear of components
Q2. How can I check if a potentiometer is working properly?
To check if a potentiometer is working properly, you can use a multimeter to measure the resistance across its terminals.
Set the multimeter to the resistance measurement mode.
Connect the multimeter leads to the outer two terminals of the potentiometer.
Slowly turn the potentiometer knob and observe the resistance value on the multimeter.
The resistance should change smoothly and continuously as you turn the knob.
If the resistance value jumps around or does not change smoothly, ...read more
Q3. What is the process by which transmission works?
Transmission works by transferring power from the engine to the wheels, allowing the vehicle to change speed and direction.
Transmission uses gears to control the power flow from the engine to the wheels
The driver selects the appropriate gear based on speed and terrain
Automatic transmissions use a torque converter to transfer power smoothly
Manual transmissions require the driver to engage and disengage gears using a clutch
CVT transmissions use a belt and pulley system to provi...read more
Q4. If vehicles unable to start how you will troubleshoot it.
I would first check the battery, then the starter motor, and finally the ignition system.
Check the battery for charge and connections
Inspect the starter motor for any issues
Test the ignition system for spark
Check for any loose wires or connections
Q5. How many types of hydraulic pump?
There are mainly two types of hydraulic pumps: gear pumps and piston pumps.
Gear pumps: simple design, cost-effective, suitable for low to medium pressure applications
Piston pumps: higher efficiency, suitable for high pressure applications, more complex design
Other types include vane pumps, radial piston pumps, and axial piston pumps
Q6. Tell us about rope pulley why required.
Rope pulleys are used to change the direction of a force, making it easier to lift heavy objects.
Rope pulleys reduce the amount of force needed to lift heavy objects by distributing the weight over multiple ropes and wheels.
They are commonly used in construction, rock climbing, and rescue operations.
Rope pulleys can also be used to create mechanical advantage, allowing for easier lifting of heavy loads.
Q7. How many types of differential?
There are mainly three types of differentials: open differential, limited-slip differential, and locking differential.
Open differential allows wheels to spin at different speeds, useful for regular driving conditions.
Limited-slip differential limits the speed difference between wheels, providing better traction.
Locking differential locks both wheels together, ensuring equal power distribution for maximum traction.
Q8. What is gear pump and displacement pump.
Gear pump and displacement pump are types of positive displacement pumps used to move fluids by trapping a fixed amount of fluid and forcing it through the pump.
Gear pump uses rotating gears to move fluid, while displacement pump moves fluid by changing the volume of a chamber.
Gear pump is more compact and efficient, while displacement pump is more accurate and suitable for high pressure applications.
Examples of gear pumps include external gear pump and internal gear pump, wh...read more
Q9. What is a torque converter?
A torque converter is a fluid coupling that transfers power from the engine to the transmission in an automatic vehicle.
It allows the engine to keep running while the vehicle is stopped
It multiplies torque to increase power output
Consists of three main components: impeller, turbine, and stator
Commonly found in automatic transmission vehicles
Q10. what is CAN bus system
CAN bus system is a communication protocol used in vehicles to allow microcontrollers and devices to communicate with each other.
CAN stands for Controller Area Network
It is a two-wire communication system
It allows for real-time data transmission between devices
It is commonly used in automotive and industrial applications
Examples of devices that use CAN bus include engine control units, airbag systems, and anti-lock brake systems
Q11. Compressor details, types of compressor
Compressors are devices that increase the pressure of a gas or vapor.
Positive displacement compressors: reciprocating, rotary screw, rotary vane
Dynamic compressors: centrifugal, axial flow
Compressors can be classified based on their cooling method: air-cooled or water-cooled
Compressors can also be classified based on their lubrication method: oil-lubricated or oil-free
Q12. Type of pump and there work
Pumps are devices used to move fluids from one place to another. There are various types of pumps, each with their own unique working principle.
Centrifugal pumps use a rotating impeller to create a flow of fluid.
Positive displacement pumps use a mechanical means to move fluid, such as a piston or diaphragm.
Axial flow pumps move fluid parallel to the axis of rotation.
Jet pumps use a high-pressure fluid to create a low-pressure suction force.
Submersible pumps are designed to op...read more
Q13. different types of pump
There are various types of pumps used in different industries such as centrifugal, positive displacement, and axial flow pumps.
Centrifugal pumps are commonly used in water treatment, chemical processing, and HVAC systems.
Positive displacement pumps are used in food processing, oil and gas, and pharmaceutical industries.
Axial flow pumps are used in irrigation, flood control, and water supply systems.
Other types of pumps include jet pumps, gear pumps, and peristaltic pumps.
Each...read more
Q14. Define torque converter.
A torque converter is a fluid coupling that transfers power from the engine to the transmission in an automatic vehicle.
Transfers power from the engine to the transmission
Uses fluid to transmit power
Allows the engine to keep running while the vehicle is stopped
Improves fuel efficiency and smoothness of gear changes
Q15. Unit of voltage in electrical
The unit of voltage in electrical is volts (V).
The unit of voltage is represented by the symbol V.
Voltage is the difference in electric potential between two points in a circuit.
Common examples of voltage include 120V in household outlets and 12V in car batteries.
