Vishwakarma Auto Parts Interview Questions and Answers

To check hydro test on a heat exchanger, perform visual inspection, pressure testing, and leak testing.

• Perform a visual inspection of the heat exchanger for any visible damages or defects.

• Conduct a pressure test by filling the heat exchanger with water or another suitable test medium and gradually increasing the pressure to the specified test pressure.

• Monitor the pressure for a specified duration to ensure it remains stable without any significant drop.

• Perform leak testing by...read more

The number of gaskets in a heat exchanger varies depending on the design and size of the heat exchanger.

• The number of gaskets in a heat exchanger can range from a few to hundreds, depending on the number of plates or tubes in the heat exchanger.

• Plate heat exchangers typically have multiple gaskets between each plate, while shell and tube heat exchangers have gaskets between the tubes and the shell.

• The number of gaskets also depends on the type of gasket used and the specific ...read more

The number of heat exchangers depends on the specific project requirements and design.

• The number of heat exchangers can vary greatly depending on the size and complexity of the project.

• It is common to have multiple heat exchangers in industrial plants and refineries.

• The number of heat exchangers may also depend on the type of process being carried out.

• For example, a petrochemical plant may have dozens of heat exchangers to facilitate various chemical reactions.

• In contrast, a ...read more

There are several types of gears, including spur, helical, bevel, worm, rack and pinion, and planetary gears.

• Spur gears have straight teeth and are the most common type.

• Helical gears have angled teeth and produce less noise and vibration than spur gears.

• Bevel gears are used to transmit power between shafts that are at an angle to each other.

• Worm gears are used to transmit power at a right angle and have high gear ratios.

• Rack and pinion gears are used to convert rotational mot...read more
