Mechanical Maintenance Fittar , ITI Fittar Interview Questions and Answers

Barniyar caliper, also known as a Vernier caliper, is a precision measuring instrument used to measure internal and external dimensions.

• It consists of a main scale and a sliding Vernier scale for precise measurements.

• Commonly used in mechanical engineering for measuring diameters, depths, and lengths.

• Example: Measuring the diameter of a cylindrical object like a pipe.

• It can measure to an accuracy of 0.02 mm or finer, depending on the model.

The type of machine can vary depending on the specific industry and application.

• Machines can be categorized based on their function, such as milling machines, lathe machines, or drilling machines.

• They can also be classified based on their power source, such as electric machines, hydraulic machines, or pneumatic machines.

• Different industries may have their own specific types of machines, like printing machines in the printing industry or CNC machines in the manufacturing indus...read more

Hydraulic working compressors can face issues that prevent their operation, requiring maintenance and troubleshooting.

• Check for hydraulic fluid leaks, which can lead to loss of pressure.

• Inspect the hydraulic pump for wear or damage; a faulty pump can halt operation.

• Ensure all connections and hoses are secure to prevent air from entering the system.

• Monitor the hydraulic fluid level; low levels can cause the compressor to malfunction.

• Examine the compressor's electrical componen...read more

• 5. Check V...read more

Pumps are mechanical devices used to move fluids by converting mechanical energy into hydraulic energy.

• Pumps are used in various applications like water supply, irrigation, and industrial processes.

• They can be classified into positive displacement pumps and centrifugal pumps.

• For example, a centrifugal pump is commonly used in water treatment plants.

• Positive displacement pumps are often used in oil and gas industries for transferring viscous fluids.

• Pumps require regular mainte...read more

Pump is a mechanical device used to move fluids or gases by mechanical action, often converting energy into hydraulic energy.

• Pumps are used in various applications, such as water supply systems, irrigation, and industrial processes.

• Common types of pumps include centrifugal pumps, positive displacement pumps, and diaphragm pumps.

• For example, a centrifugal pump uses rotational energy to move fluid, while a positive displacement pump moves fluid by trapping a fixed amount and fo...read more
