Parameters checked in installation of reactor mech seal include alignment, clearance, pressure, and temperature.
Alignment of the seal with the shaft and other components is crucial for proper functioning.
Clearance between the seal faces should be within specified limits to prevent leakage.
Pressure conditions should be monitored to ensure the seal can withstand the operating conditions.
Temperature limits should be consi...
Glass line thickness can be checked using ultrasonic thickness gauges.
Ultrasonic thickness gauges use high-frequency sound waves to measure the thickness of materials.
The gauge is placed on the glass surface and sends sound waves through the glass.
The time taken for the sound waves to bounce back is measured and used to calculate the thickness of the glass.
The thickness can be compared to the required specifications to...
SS304 and SS316 are both stainless steel alloys, but with different compositions and properties.
SS304 contains 18% chromium and 8% nickel, while SS316 contains 16% chromium, 10% nickel, and 2% molybdenum.
SS316 is more resistant to corrosion and pitting than SS304, especially in chloride environments.
SS316 is also more expensive than SS304.
SS304 is commonly used in food processing equipment, while SS316 is used in marin
An ejector system is used to create a vacuum by using a high-pressure fluid to entrain a low-pressure fluid.
The ejector system consists of a motive fluid nozzle, a suction chamber, and a diffuser.
The motive fluid is usually steam or compressed air.
The suction chamber is where the low-pressure fluid is entrained and mixed with the motive fluid.
The diffuser is where the mixed fluid expands and the pressure decreases, cre...
NPSH is the Net Positive Suction Head required to avoid cavitation in a pump. It can be checked using a formula or a graph.
NPSH is the minimum pressure required at the suction side of the pump to avoid cavitation.
It is calculated using the formula NPSH = (P1 - P2)/ρg - h1 - h2, where P1 is the pressure at the pump suction, P2 is the vapor pressure of the fluid, ρ is the fluid density, g is the acceleration due to gravi...
Spark testing can be checked by using a spark tester to measure the strength and consistency of the spark.
Use a spark tester to check the strength and consistency of the spark
Ensure that the spark is strong and consistent across all cylinders
Check for any irregularities or abnormalities in the spark pattern
Compare the results to manufacturer specifications
Make any necessary adjustments or repairs to improve the spark p

There are various types of gearboxes used in maintenance fitting, including spur gearboxes, helical gearboxes, bevel gearboxes, and worm gearboxes.
Spur gearboxes have straight teeth and are commonly used in applications with low to moderate speeds and loads.
Helical gearboxes have angled teeth and provide smoother and quieter operation compared to spur gearboxes.
Bevel gearboxes are used to transmit power between shafts ...
Pitch is the distance between two adjacent threads in a screw or bolt.
Pitch is measured in millimeters or inches.
It determines the tightness of the screw or bolt.
Different types of pitch include coarse, fine, and extra fine.
Pitch is important in alignment as it affects the positioning of rotating machinery.
Misaligned pitch can cause vibration, noise, and premature wear and tear.
Misalignment is when two or more parts are not properly aligned. Backless refers to a type of shoe without a back.
Misalignment can cause wear and tear on machinery and decrease efficiency.
Examples of misalignment include a crooked belt on a conveyor or a misaligned shaft in a motor.
Backless shoes are typically sandals or slip-ons that do not have a heel or back portion.
Backless shoes can be more comfortable in hot weat

Electrical energy is the energy carried by moving electrons in an electric conductor.
Electrical energy is a form of energy that results from the movement of charged particles.
It is measured in joules (J) or kilowatt-hours (kWh).
Examples of electrical energy include lightning, batteries, and power plants.
It can be converted into other forms of energy, such as mechanical energy or heat energy.
Electrical energy is essenti...

Flash point is the lowest temperature at which a chemical can vaporize to form an ignitable mixture in air.
Flash point is important for determining the safe handling and storage of chemicals.
It is measured using a closed cup or open cup method.
Examples of chemicals with low flash points include gasoline and acetone.
Chemicals with high flash points include diesel fuel and motor oil.
