Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
QT GLF-D Mechanical Seal
|
A high - performance mechanical seal designed for multiple industrial pumping applications, ensuring reliable operation and efficient sealing.
|
|
Model
|
QT GLF-D
|
Specifically engineered to meet the demands of various working conditions, providing stable and long - lasting sealing performance.
|
|
Materials
|
|
|
|
- Rotating Ring
|
Silicon Carbide (SiC)
|
SiC is utilized for its high hardness and excellent wear - resistance, enabling the rotating ring to endure high - speed and high - pressure operations, thus extending the overall lifespan of the seal.
|
|
- Stationary Ring
|
Tungsten Carbide
|
Tungsten carbide offers superior mechanical strength and wear - resistance, ensuring a stable seal interface and reducing the risk of leakage.
|
|
- O - Ring
|
Fluoroelastomer (FKM)
|
The FKM O - ring provides a tight seal and is resistant to a wide variety of chemicals and temperature variations, guaranteeing reliable performance.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
25 - 60 mm
|
This seal can be installed on shafts with diameters within this range, making it suitable for numerous pump shaft sizes in different industrial setups.
|
|
Seal Chamber Inner Diameter
|
35 - 70 mm
|
Designed to fit into seal chambers with inner diameters in this range, ensuring proper installation and optimal operation.
|
|
Seal Width
|
9 mm
|
The 9 - mm width is carefully optimized to balance effective sealing and minimize frictional losses, enhancing the seal's overall efficiency.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 2.0 MPa
|
Under normal operating conditions, the seal can withstand a maximum pressure of 2.0 MPa, effectively preventing the leakage of the pumped medium.
|
|
Working Temperature
|
-25ºC - 180ºC
|
Capable of operating efficiently within this wide temperature range, making it suitable for both extremely cold and high - temperature industrial applications.
|
|
Linear Velocity
|
Maximum 12 m/s
|
The seal is engineered to handle a maximum linear velocity of 12 m/s, ensuring stable performance even at high rotational speeds.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Suitable for pure water, industrial wastewater, and various water - based solutions with a pH value ranging from 2 to 13.
|
|
|
- Oil - based Fluids
|
Applicable to common lubricating oils, industrial hydraulic oils, and certain petroleum - based fluids.
|
|
|
- Chemical Solutions
|
Resistant to many acidic and alkaline chemical solutions, excluding highly concentrated strong acids and alkalis.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
Installed axially onto the pump shaft following a precise installation procedure to ensure correct alignment and a secure seal.
|
|
Installation Torque
|
18 - 22 N·m
|
During installation, a torque within this range should be applied to fasten the seal properly, avoiding damage from over - tightening or loose installation.
|
|
Maintenance Cycle
|
Every 4000 operating hours
|
Regular maintenance is advised every 4000 operating hours, which includes inspecting the seal for signs of wear, leakage, and misalignment.
|
|
Storage Conditions
|
Store in a dry, cool environment with a temperature between 5ºC - 25ºC. Keep away from direct sunlight and any potential sources of chemical contamination.
|
Proper storage conditions help maintain the integrity of the seal components and prevent premature degradation.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 2 - 3.5 years under normal operating conditions
|
With proper operation and regular maintenance, the QT GLF - D seal can provide reliable service for 2 to 3.5 years.
|
|
Leakage Rate
|
≤0.15 mL/h
|
Engineered to have a low leakage rate, ensuring that the pumped medium remains contained within the system, reducing the risk of environmental pollution and product loss.
|
|
Certification Standards
|
ISO 9001, ISO 14001
|
Meets the requirements of ISO 9001 quality management system standards and ISO 14001 environmental management system standards, ensuring high - quality production and environmental sustainability.
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 8 - 60 Hz and an amplitude of 0.6 mm.
|
Designed to maintain its sealing performance even in environments with significant vibrations, common in many industrial settings.
|
|
Self - lubricating Property
|
The seal surfaces are treated with a special self - lubricating coating, reducing friction and wear.
|
This self - lubricating feature extends the service life of the seal and minimizes the need for additional lubrication, reducing maintenance costs.
