|
Product Name
|
QT - coupling Mechanical Seal
|
|
Model Number
|
[Specific model numbers if applicable]
|
|
Seal Type
|
[Describe the type, e.g., single mechanical seal, double mechanical seal]
|
|
Application
|
[List the typical applications, such as pumps in chemical plants, industrial mixers, etc.]
|
|
Shaft Diameter Range
|
[Minimum shaft diameter] - [Maximum shaft diameter] mm This range indicates the size of shafts for which the QT - coupling mechanical seal can be effectively installed. It is crucial to ensure that the shaft diameter falls within this range to achieve proper sealing performance.
|
|
Housing Bore Diameter
|
[Minimum housing bore diameter] - [Maximum housing bore diameter] mm The housing bore diameter is an important dimension as it must match the outer diameter of the mechanical seal housing. A proper fit in the housing bore is essential for the stability and correct functioning of the seal.
|
|
Seal Face Diameter
|
[Inner seal face diameter] - [Outer seal face diameter] mm The seal face diameter determines the contact area between the sealing faces. A larger seal face diameter may be required for applications with higher pressures or larger flow rates, as it can distribute the load more evenly and enhance the sealing effectiveness.
|
|
Axial Length
|
[Axial length value] mm The axial length of the mechanical seal is significant for installation purposes. It needs to be compatible with the axial space available in the equipment where it will be installed. Any mismatch in axial length can lead to improper installation and subsequent seal failure.
|
|
Radial Width
|
[Radial width value] mm This parameter affects the overall size and strength of the mechanical seal. The radial width should be sufficient to withstand the forces acting on the seal during operation, such as centrifugal forces and pressure differentials.
|
|
Material of Construction
|
- Rotating Ring: [Material name] This material is chosen for its excellent wear resistance and compatibility with the media being sealed. It must be able to withstand the mechanical and chemical stresses during operation. - Stationary Ring: [Material name] The stationary ring material also needs to have good wear - resistance and chemical stability. It forms a sealing interface with the rotating ring, and the combination of these two materials is critical for achieving reliable sealing. - Spring: [Material name] The spring material should have high elasticity and corrosion resistance. It provides the necessary force to maintain contact between the seal faces and compensate for any wear or misalignment over time. - O - Ring (if applicable): [Material name] The O - ring material is selected for its ability to provide a secondary seal and prevent leakage along the periphery of the mechanical seal. It should have good flexibility and chemical resistance to the media and operating environment.
|
|
Pressure Rating
|
[Minimum pressure] - [Maximum pressure] bar This indicates the range of pressures that the QT - coupling mechanical seal can handle. Operating within this pressure range ensures that the seal can maintain its integrity and prevent leakage. Exceeding the maximum pressure rating may cause seal failure due to excessive stress on the seal components.
|
|
Temperature Range
|
[Minimum temperature] - [Maximum temperature] °C The mechanical seal must be able to operate within this temperature range without degradation of its materials or performance. Extreme temperatures can affect the flexibility of elastomers (if present), the mechanical properties of metals, and the overall sealing effectiveness.
|
|
Speed Limit
|
[Maximum rotational speed] rpm This parameter is important for applications involving rotating shafts. The QT - coupling mechanical seal is designed to operate at speeds up to this limit. Excessive speed can generate high centrifugal forces, which may cause imbalance, increased wear, and ultimately seal failure.
|
|
Leakage Rate
|
[Maximum allowable leakage rate] [Units, e.g., mL/h] A low leakage rate is a key performance indicator of a mechanical seal. The QT - coupling mechanical seal is engineered to keep the leakage rate within this specified limit, ensuring environmental safety and efficient operation of the equipment.
|
|
Lubrication Requirement
|
[Describe the lubrication method, e.g., self - lubricating due to the nature of the media, or requires external lubrication] Proper lubrication is essential for reducing friction between the seal faces and prolonging the service life of the mechanical seal. Understanding the lubrication requirement is crucial for the correct installation and operation of the seal.
|
|
Installation Torque
|
[Recommended installation torque value] N·m When installing the mechanical seal, applying the correct installation torque is vital. Insufficient torque may result in a loose fit and leakage, while excessive torque can damage the seal components.
|
|
Service Life
|
[Expected service life under normal operating conditions] hours This gives an estimate of how long the QT - coupling mechanical seal is expected to function properly before requiring replacement. The service life can be affected by factors such as operating conditions, maintenance practices, and the quality of the installation.
|
|
Seal Face Flatness
|
[Flatness tolerance value] µm The flatness of the seal faces is critical for achieving a tight seal. Any deviation from the specified flatness tolerance can lead to leakage paths between the seal faces.
|
|
Seal Face Roughness
|
[Roughness value, e.g., Ra value] µm An appropriate seal face roughness is necessary to ensure proper lubrication film formation between the seal faces. Too rough or too smooth a surface can negatively impact the sealing performance.
