Hydrodyne Industries Interview Questions and Answers

Bore of cylinder is decided based on pressure and load given.

• Calculate the force required to move the load

• Determine the pressure required to generate the force

• Select a cylinder with a bore size that can generate the required pressure

• Consider safety factors and application requirements

• Consult industry standards and guidelines

• Example: For a load of 1000 N and pressure of 10 bar, bore size can be calculated using formula:...read more

Relief valve, check valve and flow control valve are types of valves used in fluid systems.

• Relief valve is used to release excess pressure in a system to prevent damage or failure.

• Check valve allows fluid to flow in one direction only, preventing backflow and protecting equipment.

• Flow control valve regulates the flow rate of fluid in a system, maintaining a constant flow rate or adjusting it as needed.

• Examples of relie...read more

The testing standard for cylinders depends on the type of cylinder and its intended use.

• Cylinders used for compressed gases are tested according to DOT regulations in the US.

• Cylinders used for liquefied gases are tested according to UN regulations.

• Cylinders used for medical gases are tested according to ISO standards.

• Testing typically involves hydrostatic testing to ensure the cylinder can withstand pressure.

• Cylinders ...read more
