Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
Queeny-ST Mechanical Seal
|
A high - performance mechanical seal meticulously designed for multiple industrial pumping systems, ensuring reliable and long - lasting sealing performance
|
|
Model
|
Queeny-ST
|
Specifically engineered to adapt to a wide range of operating conditions and fluid handling requirements
|
|
Materials
|
|
|
|
- Rotating Ring
|
Tungsten Carbide (WC)
|
Tungsten carbide offers exceptional hardness and wear resistance, enabling the rotating ring to endure high - speed rotations and heavy loads, thus extending the seal's service life
|
|
- Stationary Ring
|
Silicon Nitride
|
Silicon nitride provides excellent corrosion resistance and low friction, ensuring a smooth sealing surface and efficient operation
|
|
- O - Ring
|
Ethylene Propylene Diene Monomer (EPDM)
|
EPDM O - ring ensures a tight seal and is highly resistant to water, steam, and various non - polar solvents, making it suitable for diverse media
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
18 - 45 mm
|
Compatible with pump shafts within this diameter range, suitable for different pump models and sizes
|
|
Seal Chamber Inner Diameter
|
28 - 55 mm
|
Designed to fit into seal chambers with inner diameters in this range, guaranteeing proper installation and optimal sealing
|
|
Seal Width
|
8.5 mm
|
The 8.5 - mm width is optimized to balance sealing effectiveness and reduce friction, enhancing the overall efficiency of the pumping system
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 1.5 MPa
|
Under normal operating conditions, the Queeny-ST seal can withstand a maximum pressure of 1.5 MPa, preventing fluid leakage and maintaining system integrity
|
|
Working Temperature
|
-30ºC - 130ºC
|
Capable of operating efficiently within this temperature range, suitable for both cold - storage and moderately high - temperature industrial applications
|
|
Linear Velocity
|
Maximum 10.5 m/s
|
Engineered to handle a maximum linear velocity of 10.5 m/s, ensuring stable performance even at high - speed pump operations
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Suitable for potable water, cooling water, and water - based chemical solutions with a pH range of 4 - 10
|
|
|
- Oil - based Fluids
|
Can be used with mineral oils, vegetable oils, and some synthetic lubricating oils
|
|
|
- Gas - liquid Mixtures
|
Effective in sealing systems handling gas - liquid mixtures, such as in some chemical reaction processes
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
Installed axially onto the pump shaft following a standardized installation procedure to ensure accurate alignment and a secure seal
|
|
Installation Torque
|
13 - 17 N·m
|
During installation, applying a torque within this range secures the seal properly without causing damage to its components
|
|
Maintenance Cycle
|
Every 3500 operating hours
|
Regular maintenance every 3500 operating hours is recommended, including inspection for wear, leakage, and proper alignment of the seal
|
|
Storage Conditions
|
Store in a dry, shaded environment at a temperature between 8ºC - 22ºC, away from chemicals and direct sunlight
|
Proper storage conditions preserve the integrity of the seal materials and ensure its readiness for installation
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 2 - 2.5 years under normal operating conditions
|
With proper operation and maintenance, the Queeny-ST seal can provide reliable service for 2 - 2.5 years, reducing downtime and replacement costs
|
|
Leakage Rate
|
≤0.09 mL/h
|
Engineered to have an extremely low leakage rate, ensuring minimal fluid loss and meeting strict environmental and operational requirements
|
|
Certification Standards
|
ISO 9001, ISO 14001, ISO 44001
|
Meets the requirements of ISO 9001 quality management system, ISO 14001 environmental management system, and ISO 44001 collaborative business relationship management system, demonstrating high - quality standards and environmental responsibility
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 6 - 45 Hz and an amplitude of 0.45 mm
|
Designed to maintain sealing performance in environments with moderate vibration levels, ensuring stable pump operation
|
|
Self - lubricating Property
|
The seal surfaces are coated with a special self - lubricating material, reducing friction and wear
|
This self - lubricating feature improves the seal's durability and reduces energy consumption during operation
