Thriveni Earthmovers Interview Questions, Process, and Tips

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...read more

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...read more

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...read more

Possible causes of slow hydraulic cylinder operation

• Low hydraulic fluid level

• Clogged or dirty hydraulic filter

• Worn out piston seals

• Leaking hydraulic lines

• Faulty control valve

• Incorrectly adjusted relief valve

• Excessive load on the cylinder

• Improperly sized cylinder for the application

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

• To ha...read more

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...read more

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...read more

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
