Bumping clearance in a reciprocating compressor is the minimum distance between the piston and the cylinder head at the top dead center.

• Bumping clearance is crucial to prevent contact between the piston and the cylinder head during operation.

• It is necessary to allow for thermal expansion of the components and to avoid damage.

• Proper bumping clearance ensures efficient operation and prolongs the lifespan of the compresso...read more

A mechanical seal is a device that helps prevent leakage between two moving or stationary parts in a machine.

• Used in pumps, compressors, and other rotating equipment

• Consists of two main parts: stationary seal face and rotating seal face

• Common types include cartridge seals, component seals, and split seals

Pressure vessels are made in cylindrical or spherical shapes for structural integrity, ease of fabrication, and efficient use of material.

• Cylindrical shape provides uniform stress distribution and is easier to fabricate compared to other shapes.

• Spherical shape can withstand higher internal pressure due to uniform stress distribution in all directions.

• Cylindrical shape is commonly used for horizontal pressure vessels li...read more

ASME codes are primarily used for pressure vessels and piping systems, while API codes are focused on the oil and gas industry.

• ASME codes are more general and cover a wide range of industries, while API codes are specific to the oil and gas industry.

• ASME codes are developed by the American Society of Mechanical Engineers, while API codes are developed by the American Petroleum Institute.

• ASME codes focus on design, cons...read more

Micro alloy elements added to alloy steel improve strength, toughness, and hardenability.

• Common micro alloy elements include vanadium, niobium, titanium, and boron.

• These elements help refine the grain structure of the steel, resulting in improved mechanical properties.

• Micro alloying also allows for the use of lower carbon content, reducing the risk of cracking during heat treatment.

Safety is a crucial aspect in engineering to prevent accidents and ensure the well-being of individuals.

• Safety protocols should be followed at all times in the workplace

• Regular safety inspections and audits should be conducted

• Proper training and education on safety procedures is essential

• Use of personal protective equipment (PPE) is mandatory in hazardous environments

Relays are electrically operated switches that control high power circuits with low power signals. Types include electromechanical, solid state, and reed relays.

• Relays work by using an electromagnet to mechanically switch contacts open or closed.

• Types of relays include electromechanical relays, solid state relays, and reed relays.

• Electromechanical relays use an electromagnet to operate mechanical contacts.

• Solid state r...read more

A single line diagram is a simplified diagram that shows the electrical connections and components of a power system in a single line.

• It is used to represent the electrical system in a simplified manner.

• It shows the connections between various components like generators, transformers, circuit breakers, etc.

• It helps in understanding the overall layout of the system and how different components are interconnected.

• It is c...read more
