Rotary Engineer Interview Questions and Answers

I have worked extensively with rotary equipment in various industries.

• Designed and implemented maintenance programs for rotary pumps and compressors

• Troubleshot and repaired rotary engines in heavy machinery

• Managed installation and commissioning of rotary kilns in cement plants

• Optimized performance of rotary dryers in chemical processing plants

• Conducted training sessions for operators on safe and efficient use of rotary equipment

Types of pumps include centrifugal, reciprocating, and rotary pumps. They work by creating a flow of liquid through mechanical action. Characteristics include flow rate, pressure, efficiency, and power consumption.

• Centrifugal pumps use a rotating impeller to create a flow of liquid by centrifugal force.

• Reciprocating pumps use a piston or diaphragm to create a flow of liquid by reciprocating motion.

• Rotary pumps use rotating elements to create a flow of liquid by displacement.

Mechanical seals are used to prevent leakage in rotary equipment by creating a barrier between moving and stationary parts.

• Mechanical seals can be classified into various types such as pusher seals, non-pusher seals, balanced seals, unbalanced seals, cartridge seals, and split seals.

• They work by maintaining a thin film of liquid or gas between the sealing faces to prevent leakage.

• The seal faces are typically made of materials like carbon, ceramic, or tungsten carbide to withs...read more

Bearings can be identified by their size, shape, material, and markings.

• Check the size and shape of the bearing to determine its type (e.g. ball bearing, roller bearing)

• Look for any markings or labels on the bearing that indicate the manufacturer or part number

• Identify the material of the bearing (e.g. steel, ceramic) by visual inspection or using a magnet

• Measure the inner and outer diameter, width, and type of bearing to further identify it
