I applied via Naukri.com and was interviewed in Mar 2024. There was 1 interview round.
Hydraulic system operation involves the use of fluid to transmit power and control machinery.
Hydraulic systems use a fluid, typically oil, to transmit power.
The system consists of a pump, valves, actuators, and fluid reservoir.
The pump pressurizes the fluid, which is then directed to the actuators.
The actuators convert the fluid pressure into mechanical force to perform work.
Valves control the flow and direction of the...
Series and parallel connections are different ways of connecting electrical components, while star-delta connection is a method used for three-phase motors.
In series connection, components are connected end-to-end, creating a single path for current flow.
In parallel connection, components are connected side by side, creating multiple paths for current flow.
Series connection increases total resistance and decreases tota...

I was interviewed in Mar 2023.
Pump is used to transfer fluids while motor is used to convert electrical energy into mechanical energy.
Pump is used to move fluids from one place to another while motor is used to rotate machinery.
Pump has an inlet and outlet while motor has a rotor and stator.
Pump is used in fluid systems while motor is used in mechanical systems.
Examples of pumps include centrifugal pumps, positive displacement pumps, and axial flow...
Series and parallel connections are two types of electrical circuits used to connect components.
In a series connection, components are connected end-to-end, so the current flows through each component in turn.
In a parallel connection, components are connected side-by-side, so the current is divided among them.
Series connections increase the total resistance and decrease the total current, while parallel connections dec...
The fuel system is responsible for delivering fuel to the engine for combustion.
The fuel system includes the fuel tank, fuel pump, fuel filter, fuel injectors, and carburetor.
The fuel pump draws fuel from the tank and sends it to the engine.
The fuel filter removes impurities from the fuel before it reaches the engine.
Fuel injectors spray fuel into the engine's combustion chamber, while a carburetor mixes fuel and air b...
Possible causes of slow hydraulic cylinder operation
Low hydraulic fluid level
Clogged or dirty hydraulic filter
Worn out piston seals
Leaking hydraulic lines

Control valve internal leakages can be checked through various methods.
Performing a visual inspection of the valve and its components
Using ultrasonic leak detection equipment
Conducting a pressure drop test
Performing a bubble test using a soap solution
Checking the valve position indicator
Analyzing the valve's performance data
Regular maintenance and testing of the valve
Breaking failure can be solved by identifying the root cause and implementing corrective actions.
Identify the root cause of the breaking failure
Implement corrective actions such as repairing or replacing the broken parts
Conduct regular maintenance and inspections to prevent future breaking failures
Train employees on proper usage and maintenance of equipment
Use high-quality materials and equipment to reduce the risk of

I applied via Naukri.com and was interviewed in Apr 2023. There were 2 interview rounds.
Delay analysis is the process of identifying and analyzing the causes of project delays.
It involves reviewing project schedules and identifying any deviations from the planned timeline
It also involves identifying the causes of the delays, such as changes in scope, unforeseen events, or resource constraints
Delay analysis can help determine who is responsible for the delays and can be used to support claims for additiona...
I applied via Approached by Company and was interviewed before Aug 2023. There was 1 interview round.
I applied via Approached by Company and was interviewed before Dec 2023. There was 1 interview round.
Self motor is not a commonly used term in electrical engineering.
It is possible that the interviewer meant to ask about self-starting motors, which are motors that can start without external assistance.
Another possibility is that they were referring to self-excited motors, which generate their own magnetic field without the need for a separate excitation source.
It is important to clarify the question with the interview
Alternators are electrical generators that convert mechanical energy into electrical energy.
Alternators are commonly used in vehicles to charge the battery and power the electrical system.
They work by using a rotating magnetic field to induce an electrical current in a stationary coil of wire.
Alternators are more efficient and reliable than traditional generators.
They are also smaller and lighter, making them ideal for...
Batteries are devices that store chemical energy and convert it into electrical energy.
Batteries come in various sizes and types, including alkaline, lithium-ion, and lead-acid.
They are commonly used in electronic devices, vehicles, and backup power systems.
Batteries have a positive and negative terminal, and the flow of electrons between them creates an electrical current.
The capacity of a battery is measured in amper
