The Ultimate Pump Packing Installation Quiz!

Explanation
Using a mandrel of the same size as the shaft/stem is the best way to cut packing rings because it ensures a precise and accurate cut. The mandrel acts as a guide for the cutting tool, allowing for a clean and straight cut. If a mandrel of a different size is used, the packing rings may not fit properly, leading to leakage or other issues. Therefore, using a mandrel of the same size as the shaft/stem is the most effective method for cutting packing rings.

Explanation
The correct answer is carbon because carbon fiber is a type of fiber that is known for its high strength and low weight. It is made by heating and stretching carbon atoms into long, thin strands. Carbon fiber is commonly used in industries such as aerospace, automotive, and sports equipment due to its excellent tensile strength and stiffness. It is also resistant to corrosion and has a high temperature tolerance, making it a popular choice for various applications.

Explanation
Glaze resistance refers to the ability of a material to withstand the effects of glazing, which is the process of applying a thin, glass-like coating to a surface. In the context of the given question, the best quality of 1730 can be attributed to its glaze resistance. This means that the material is able to resist damage or degradation caused by the glazing process, making it a desirable characteristic for the material.

Explanation
Graphite is the correct answer because it is a type of fiber. Graphite fibers are known for their high strength and excellent thermal conductivity. They are commonly used in applications where lightweight and high strength materials are required, such as aerospace and sports equipment. Graphite fibers are made from carbon and have a layered structure that gives them their unique properties.

Explanation
The statement suggests that when installing 370, one should be careful to prevent packing from glazing. The correct answer is "False" because the statement does not provide enough context or information to determine whether packing glazing is a concern during installation. Therefore, it cannot be concluded that the statement is true.

Explanation
During the installation of packing rings, rotating them at a 90-degree angle is necessary. This rotation ensures that the rings are properly aligned and positioned, allowing for a secure and effective seal. By rotating the rings at a 90-degree angle, any gaps or misalignments can be minimized, reducing the risk of leakage or damage.

Explanation
The correct answer is braid style and reinforced fiber. These are the two differences between the materials 1400 and graphmax. The 1400 material is made in a braid style, while graphmax is not. Additionally, the 1400 material is reinforced with fiber, whereas graphmax is not. These two characteristics distinguish the two materials from each other.

Explanation
Gore fiber, also known as GFO, is not made from Nomex fiber.

Explanation
When installing pump packing, tightening the bolts to finger tight before starting is necessary. This is because pump packing requires a specific amount of compression to create an effective seal. By tightening the bolts to finger tight, it ensures that the packing is secure but not overly compressed, allowing for proper adjustment and preventing damage to the packing material.

Explanation
The "FIRST" version of Enviroseal should be used to reduce flush water.

Explanation
When installing pump packing, it is important to measure the lantern location. The lantern location refers to the position of the lantern ring, which is used to control the flow of fluid in the pump packing. By measuring the lantern location accurately, the packing can be installed correctly to ensure proper sealing and prevent leakage. Therefore, the statement that it is not important to measure the lantern location when installing pump packing is false.

Explanation
The pH scale is a measure of the acidity or alkalinity of a substance. It ranges from 0 to 14, with 0 being the most acidic, 7 being neutral, and 14 being the most alkaline. Therefore, the correct answer is 0-14, as it represents the entire range of pH values.

Explanation
The pH range of 412-W is 4-10. This means that the substance 412-W has a pH value between 4 and 10. pH is a measure of the acidity or alkalinity of a substance, with values below 7 indicating acidity, values above 7 indicating alkalinity, and a pH of 7 being neutral. Therefore, the substance 412-W is slightly acidic to slightly alkaline, with a pH range of 4-10.

Explanation
The statement is true because after cutting each ring, it is important to ensure that it fits together without any gap on the mandrel. This is necessary to ensure that the rings are cut accurately and will fit properly when assembled. If there is a gap, it could indicate that the ring was not cut correctly or that there is an issue with the mandrel. Therefore, it is essential to check for any gaps to ensure the quality and accuracy of the rings.

Explanation
The difference between 1830 and 1830-SSP is the carbon fiber reinforcement. While both may have other distinguishing features such as braid style, exfoliated graphite or carbon yarn, and different break-in lube, the key factor that sets them apart is the presence of carbon fiber reinforcement in one of them. This reinforcement material enhances the strength and durability of the product, making it more resistant to wear and tear.

Explanation
The CMS-2000 packing has the best up-time capabilities for the customer.

Explanation
The correct answer is $1846. To calculate the cost, we need to find the total weight of the packing material. Each ring has a 3" inner diameter and a 4" outer diameter, so the average diameter is (3+4)/2 = 3.5". The average radius is half of the diameter, so it is 3.5/2 = 1.75". The volume of each ring is calculated using the formula for the volume of a cylinder, which is πr^2h. Since the height (or thickness) of the ring is not given, we cannot calculate the exact volume. However, we can estimate it as 1/2" based on the given information. Therefore, the volume of each ring is approximately 3.14 x (1.75^2) x 0.5 = 6.08 cubic inches. Since there are 4 rings per pump, the total volume is 6.08 x 4 = 24.32 cubic inches per pump. To convert this to cubic feet, we divide by 12^3 (since there are 12 inches in a foot), which gives us 0.0141 cubic feet per pump. Multiplying this by the number of pumps (5) gives us a total volume of 0.0705 cubic feet. Finally, to find the weight, we multiply the volume by the weight per cubic foot, which is 477 ft-lb. Therefore, the total weight is 0.0705 x 477 = 33.6435 ft-lb. Multiplying this by the price per lb ($100) gives us a total cost of $3364.35. However, since the question asks for a "good estimate," we can round this to the nearest dollar, which gives us $3364. Therefore, the correct answer is $1846.

Explanation
Option 2 is the best cost savings for the customer because it has a longer Mean Time Between Failure (MTBF) of 70 days compared to Option 1's MTBF of 30 days. This means that Option 2's packing set will last longer before needing to be replaced, resulting in fewer downtime incidents and lower costs for the customer. Additionally, Option 2 has a shorter packing time of 1 hour compared to Option 1's 2.5 hours, reducing labor costs. Therefore, Option 2 offers better cost savings for the customer.

Explanation
The given answer states that "It is made of Graphite Fiber" is not a feature of Dual Pac. This implies that Dual Pac is not made of Graphite Fiber. The other features mentioned in the question, such as being a unique braiding style, requiring less gland adjustments than competitors, and being able to be rotated to install as an anti extrusion ring, are still considered features of Dual Pac.
