Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
QT WE Mechanical Seal
|
A high - performance mechanical seal engineered for a wide range of industrial pumping applications, ensuring reliable fluid containment.
|
|

|
[Brand Name]
|
|
|
Model
|
QT WE
|
This model is designed to offer robust sealing solutions across various operating conditions in industrial environments.
|
|
Materials
|
|
|
|
- Rotating Ring
|
Silicon Carbide (SiC)
|
Silicon carbide provides exceptional hardness and wear resistance, enabling the rotating ring to withstand high - speed and high - pressure operations, thus extending the seal's overall lifespan.
|
|
- Stationary Ring
|
Carbon Graphite
|
Carbon graphite is utilized for its low coefficient of friction and excellent self - lubricating properties, facilitating smooth operation and efficient sealing.
|
|
- O - Ring
|
Fluoroelastomer (FKM)
|
The FKM O - ring ensures a tight and secure seal, with good resistance to a broad spectrum of chemicals and temperature fluctuations.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
18 - 55 mm
|
This seal is compatible with shafts having diameters within this range, making it suitable for diverse pump sizes and types.
|
|
Seal Chamber Inner Diameter
|
28 - 65 mm
|
Specifically designed to fit into seal chambers with inner diameters in this interval, ensuring proper installation and optimal performance.
|
|
Seal Width
|
8.5 mm
|
The 8.5 - mm seal width is carefully calibrated to strike a balance between effective sealing and minimizing frictional forces.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 1.8 MPa
|
Under normal operational conditions, the seal can endure a maximum pressure of 1.8 MPa, preventing leakage of the pumped medium.
|
|
Working Temperature
|
-20ºC - 160ºC
|
Capable of operating efficiently within this temperature range, making it suitable for both cold - and high - temperature industrial processes.
|
|
Linear Velocity
|
Maximum 10.5 m/s
|
The seal is engineered to handle high - speed rotations, with a maximum linear velocity of 10.5 m/s, maintaining stable performance throughout operation.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Ideal for clean water, wastewater, and various aqueous solutions with a pH range of 3 - 12.
|
|
|
- Oil - based Fluids
|
Compatible with lubricating oils, gear oils, and most common hydraulic oils.
|
|
|
- Chemical Fluids
|
Resistant to many acids, alkalis, and solvents, but specific compatibility should be verified based on the fluid's concentration and operating conditions.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
Installed axially onto the pump shaft following a precise and standardized installation procedure to ensure correct alignment and a reliable seal.
|
|
Installation Torque
|
15 - 20 N·m
|
During installation, applying a torque within this range secures the seal firmly in place without causing damage to its components.
|
|
Maintenance Cycle
|
Every 3500 operating hours
|
Regular maintenance is recommended every 3500 operating hours, including thorough inspection for signs of wear, leakage, and proper alignment of the seal components.
|
|
Storage Conditions
|
Store in a dry, cool place with a temperature range of 0ºC - 30ºC. Keep away from direct sunlight, oxidizing agents, and corrosive gases.
|
Proper storage conditions are crucial for preserving the integrity of the seal components and preventing premature degradation.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 1.8 - 3 years under normal operating conditions
|
With proper operation and regular maintenance, the QT WE seal can provide reliable service for 1.8 - 3 years.
|
|
Leakage Rate
|
≤0.07 mL/h
|
Engineered to have a very low leakage rate, ensuring minimal loss of the pumped medium and compliance with environmental and safety standards.
|
|
Certification Standards
|
ISO 9001, ISO 14001, and relevant industry - specific certifications (such as API 682 for applicable applications)
|
Meets international quality management and environmental management system standards, as well as industry - specific requirements.
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 6 - 55 Hz and an amplitude of 0.5 mm.
|
Designed to maintain its sealing performance even in environments with significant vibration, typical of industrial pump setups.
|
|
Self - lubricating Property
|
The seal faces are coated with a specialized self - lubricating material, reducing friction and wear, and enhancing the seal's durability and operational efficiency.
