• Ensure the address is accurate and up to date.

An accumulator is a device that stores energy in the form of pressurized fluid or gas.

• It is commonly used in hydraulic systems to store energy and maintain pressure.

• Accumulators can be classified into different types such as bladder, piston, and diaphragm.

• They are used in various applications such as shock absorbers, cranes, and elevators.

• Accumulators can also be used to supplement pump flow and reduce pressure fluctua...read more

Positive displacement pumps move a fixed amount of fluid per cycle, while non-positive displacement pumps do not.

• Positive displacement pumps trap a fixed amount of fluid and force it through the discharge port with each cycle.

• Non-positive displacement pumps do not trap fluid, but instead rely on impeller or rotor action to move fluid through the pump.

• Examples of positive displacement pumps include gear pumps, piston pu...read more

A manifold is a device that connects multiple pipes or tubes to a single inlet or outlet.

• Manifolds are commonly used in plumbing and HVAC systems.

• They can be made of various materials such as brass, stainless steel, or plastic.

• Manifolds can have different configurations such as straight, angled, or curved.

• They are used to regulate the flow of fluids or gases in a system.

• Examples include a fuel manifold in an engine or

CFMEA stands for Control Failure Mode and Effects Analysis.

• CFMEA is a systematic approach used to identify and mitigate potential failures in a process or system.

• It involves analyzing failure modes, their causes, and the potential effects on the process or system.

• CFMEA helps in prioritizing and implementing control measures to prevent or minimize failures.

• It is commonly used in industries such as manufacturing, automot...read more

System level DFMEA is given main preference.

• System level DFMEA considers the entire system and its interactions.

• Component level DFMEA focuses on individual components.

• System level DFMEA is more comprehensive and effective in identifying potential failures.

• Example: In automotive industry, system level DFMEA would consider the entire vehicle and its subsystems.

• Example: In medical devices, system level DFMEA would conside...read more

A diesel generator works by converting diesel fuel into mechanical energy which is then converted into electrical energy.

• Diesel fuel is injected into the combustion chamber where it ignites and creates high pressure gases that push the piston down, creating mechanical energy.

• The mechanical energy is then converted into electrical energy through the use of an alternator.

• The alternator uses a magnetic field and a conduct...read more

A diesel engine works by compressing air in the cylinder, which heats up and ignites the fuel injected into the cylinder.

• Air is drawn into the cylinder and compressed by the piston

• The compressed air heats up and ignites the fuel injected into the cylinder

• The explosion pushes the piston down, which turns the crankshaft and powers the engine

• Diesel engines are more efficient than gasoline engines because they compress the...read more

A train doesn't need a differential because its wheels are fixed to the same axle and rotate at the same speed.

• Train wheels are fixed to the same axle

• Wheels rotate at the same speed

• Differential is used in vehicles with wheels that rotate at different speeds

• Differential allows for smooth turning

Petrol engines have lower compression ratios compared to diesel engines.

• Petrol engines have lower compression ratios to prevent knocking or detonation.

• Diesel engines have higher compression ratios to ignite the fuel without spark plugs.

• Higher compression ratios in diesel engines result in better fuel efficiency and torque.

• Petrol engines require lower compression ratios to accommodate the lower octane rating of petrol f...read more

Incremental encoder measures relative position changes while absolute encoder measures absolute position.

• Incremental encoder generates a series of pulses as the shaft rotates, which are used to determine the relative position change.

• Absolute encoder generates a unique digital code for each shaft position, providing absolute position information.

• Incremental encoder is simpler and less expensive, while absolute encoder i...read more
