I applied via Walk-in and was interviewed before Jul 2021. There were 2 interview rounds.
A hydraulic circuit diagram is a schematic representation of a hydraulic system, showing the flow of fluid and the various components involved.
A hydraulic circuit typically consists of a pump, valves, actuators, and fluid lines.
The pump is responsible for generating hydraulic pressure by converting mechanical energy into fluid flow.
Valves control the direction, flow rate, and pressure of the hydraulic fluid.
Actuators, ...
Single acting cylinders have one port for fluid to enter and exit, while double acting cylinders have two ports.
Single acting cylinders use fluid pressure to extend the piston rod and a spring to retract it.
Double acting cylinders use fluid pressure to extend and retract the piston rod.
Single acting cylinders are commonly used in applications where the load is moved in one direction only, such as in dump trucks.
Double ...
Directional valve controls the direction of fluid flow while pressure reducing valve maintains a constant downstream pressure.
Directional valve is used to control the direction of fluid flow in a hydraulic system.
Pressure reducing valve is used to maintain a constant downstream pressure in a hydraulic system.
Directional valve can be either a spool valve or a poppet valve.
Pressure reducing valve can be either a direct a...
Pressure Relief valve releases excess pressure to prevent damage, while Pressure Reducing valve reduces pressure for downstream use.
Pressure Relief valve opens when pressure exceeds set limit to prevent damage to equipment
Pressure Reducing valve reduces pressure for downstream use, maintaining a constant pressure
Pressure Relief valve is typically used in systems with no downstream pressure requirement
Pressure Reducing ...
2 stroke engines have a power stroke in every revolution, while 4 stroke engines have a power stroke in every other revolution.
2 stroke engines have a simpler design and are lighter than 4 stroke engines
2 stroke engines have a higher power-to-weight ratio than 4 stroke engines
4 stroke engines are more fuel efficient and have a longer lifespan than 2 stroke engines
4 stroke engines have a separate lubrication system, whi...
Turbocharger is used in internal combustion engines to increase power output while centrifugal compressor is used in HVAC systems to increase air pressure.
Turbocharger is driven by exhaust gases while centrifugal compressor is driven by an electric motor or a gas turbine.
Turbocharger compresses air before it enters the engine while centrifugal compressor compresses air after it enters the system.
Turbocharger is used in...
Turbocharger increases the air intake in diesel engine to improve performance.
Turbocharger uses exhaust gases to spin a turbine which compresses air intake
Compressed air has more oxygen, allowing more fuel to be burned, increasing power
Turbocharger can increase engine efficiency and reduce emissions
Commonly used in diesel trucks, boats, and heavy machinery
Compressor in diesel engine compresses air to increase its pressure and temperature.
Compressor draws in air from the atmosphere and compresses it before sending it to the engine.
The compressed air is mixed with fuel in the combustion chamber to create a high-pressure explosion that powers the engine.
The compressor is driven by the engine's crankshaft through a belt or gear system.
The compressor also helps to cool the e...
Heat exchange in hydraulic machines is used to regulate temperature and prevent overheating.
Heat exchange helps to maintain the temperature of hydraulic fluid within a safe operating range.
It prevents overheating of the hydraulic system, which can cause damage to the components.
Heat exchangers can be air-cooled or liquid-cooled, depending on the application.
Examples of hydraulic machines that use heat exchange include
A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
Pressure vessels are used in various industries such as oil and gas, chemical, pharmaceutical, and food processing.
They are designed to withstand high pressures and are typically cylindrical or spherical in shape.
Examples include boilers, storage tanks, and compressed air tanks.
Designing a shell involves considering factors like material, shape, size, and functionality.
Consider the material of the shell - metal, plastic, or composite
Determine the shape of the shell based on the intended use - cylindrical, spherical, conical, etc.
Decide on the size of the shell to accommodate the contents it will hold
Design the shell with the necessary functionality in mind - openings, closures, ventilation, e
