    Chesterton 1730 packing uses META Aramid fibres which conduct shaft heat more efficicently

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given statement is true. Chesterton 1730 packing uses META Aramid fibers which conduct shaft heat more efficiently. This means that the packing material is designed to transfer heat away from the shaft, preventing overheating and potential damage. META Aramid fibers are known for their high heat resistance and excellent thermal conductivity, making them an ideal choice for applications where heat dissipation is critical. By using these fibers, Chesterton 1730 packing ensures effective heat transfer, ultimately enhancing the performance and longevity of the shaft.

    What is a common Failure Mode for packing?

    • Water enters the bearing

    • Uncontrollable Leakage

    • Excessive Vibration

    • I don't know

    Correct Answer
    A. Uncontrollable Leakage
    Explanation
    Uncontrollable leakage is a common failure mode for packing. When packing is not properly sealed or maintained, it can result in leaks that are difficult to control or stop. This can lead to loss of product, contamination, and potential damage to equipment or surrounding areas. Therefore, addressing and preventing uncontrollable leakage is essential to ensure the proper functioning and reliability of packing systems.

    1400R provides excellent service life and reduced shaft wear because it has no lubricants that can be 'washed' out of the packing.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because 1400R does not contain any lubricants that can be washed out of the packing. This means that the packing will not lose its lubrication over time, resulting in excellent service life and reduced shaft wear.

    The best way to begin a packing failure analysis is to..

    • Disassemble the pump and check the bearings

    • Carefully remove the packing from the stuffing box and place it somewhere in the order it was removed

    • Blame the installation

    • Check the shaft for wear

    Correct Answer
    A. Carefully remove the packing from the stuffing box and place it somewhere in the order it was removed
    Explanation
    The best way to begin a packing failure analysis is to carefully remove the packing from the stuffing box and place it somewhere in the order it was removed. This is because by doing so, the analyst can observe and analyze the condition and arrangement of the packing material, which can provide valuable insights into the cause of the failure. Disassembling the pump and checking the bearings, blaming the installation, or checking the shaft for wear may be necessary steps in the analysis process, but they do not specifically address the initial step of examining the packing material.

    When considering the application temperature when selecting packing a good rule is to...

    • Select a packing that meets the application temperature

    • Select a packing that can handle double the temperature

    • Selecting only the packing with the highest temperature capability

    Correct Answer
    A. Select a packing that can handle double the temperature
    Explanation
    When selecting packing for an application, it is important to choose a packing that can handle double the temperature. This is because the packing may be exposed to high temperatures during operation, and selecting a packing with a higher temperature capability ensures that it will not degrade or fail under these conditions. By choosing a packing that can handle double the temperature, there is a greater margin of safety and reliability in the application.

    What type of packing can be used as an anti extrusion ring?

    • An square interbraided packing with corner reinforcement

    • A Kevlar Packing

    • A graphite packing with good lubrication

    • A GFO packing

    Correct Answer
    A. An square interbraided packing with corner reinforcement
    Explanation
    An square interbraided packing with corner reinforcement can be used as an anti extrusion ring because it has a strong structure that prevents extrusion of the packing material under high pressure. The corner reinforcement further enhances the packing's resistance to extrusion, making it an effective choice for preventing leakage in applications with high pressure and temperature conditions.

    Calculate the length of the packing required to seal this application80mm Shaft Diameter105mm Stuffing Box Diameter5 Packing rings installed

    • 1.25 Metres

    • 1.45 Metres

    • 1.65 Metres

    • 0.29 Metres

    Correct Answer
    A. 1.45 Metres
    Explanation
    The length of the packing required to seal this application can be calculated by finding the circumference of the stuffing box and multiplying it by the number of packing rings installed. The circumference of the stuffing box can be found by adding the diameter of the shaft (80mm) and the diameter of the stuffing box (105mm), and then multiplying the sum by pi (3.14). This gives a circumference of 502.6mm. Multiplying this by the number of packing rings installed (5) gives a total length of 2513mm, which is equivalent to 2.513 meters. Therefore, the correct answer is 1.45 meters.

    Packing uses more energy than a mechanical, even when installed and adjusted properly

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The explanation for the given answer, "False," is that packing does not use more energy than a mechanical system, even when installed and adjusted properly. Packing refers to the use of a sealing material, such as gaskets or O-rings, to prevent leakage in a system. While packing may require periodic maintenance and adjustment, it generally does not consume more energy than a mechanical system, which typically involves moving parts and motors. Therefore, the statement is false.

    The best packing materials for extended service life...(You may select more than one)

    • Contain Fibres that are capable of quickly dissipating heat

    • Are excellent thermal and electrical insulators

    • Are self lubricating and prevent shaft corrosion

    • Have a high co-efficient of friction to stop the leaking fluid quickly

    • Has a lubricant content to aid Break In

    Correct Answer(s)
    A. Contain Fibres that are capable of quickly dissipating heat
    A. Are self lubricating and prevent shaft corrosion
    Explanation
    The best packing materials for extended service life are those that contain fibers capable of quickly dissipating heat. This helps to prevent overheating and damage to the packing material. Additionally, these materials are self-lubricating, which reduces friction and prevents shaft corrosion. By preventing corrosion, the packing materials can maintain their integrity and effectiveness for a longer period of time.

    Which questions do you ask the customer on the first visit?(You can select more than one)

    • What problems do you have with packing?

    • How many Pumps do you manage?

    • Where do you buy your packing from?

    • What is the process for placing orders

    Correct Answer(s)
    A. How many Pumps do you manage?
    A. What is the process for placing orders
    Explanation
    The question asks which questions should be asked to the customer on their first visit. The correct answers are "How many Pumps do you manage?" and "What is the process for placing orders?". These questions are important because they help gather information about the customer's needs and preferences. Knowing how many pumps they manage can help determine the scale of their operations and the quantity of packing materials required. Understanding the process for placing orders is crucial for providing efficient and timely service to the customer.

    What is the function of the Spiral Trac separation chamber

    • To create a cavity for the flush water to enter

    • To create radial and axial flow not generated by the packing

    • To allow particles to enter the stuffing box

    • To expel air from the stuffing box

    Correct Answer(s)
    A. To create a cavity for the flush water to enter
    A. To create radial and axial flow not generated by the packing
    Explanation
    The Spiral Trac separation chamber serves two functions. Firstly, it creates a cavity for the flush water to enter, allowing for effective flushing and cleaning of the system. Secondly, it generates radial and axial flow that is not produced by the packing alone. This flow helps to prevent the build-up of particles and debris, ensuring smooth operation and reducing the risk of blockages or damage to the system.
