Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
QT-PTFE seal-01 Mechanical Seal
|
A high-performance mechanical seal designed for diverse industrial applications, offering reliable sealing solutions.
|
|
Model
|
QT-PTFE seal-01
|
Specifically engineered to meet the demanding requirements of various pumping systems.
|
|
Materials
|
|
|
|
- Rotating Ring
|
Silicon Carbide (SiC)
|
Renowned for its superior hardness and wear resistance, SiC enables the rotating ring to endure high-speed and high-pressure operations, ensuring a long service life.
|
|
- Stationary Ring
|
Tungsten Carbide (WC)
|
Tungsten carbide provides excellent strength and corrosion resistance, creating a stable and effective sealing surface.
|
|
- O-Ring
|
Fluoroelastomer (FKM)
|
FKM O-ring offers a tight seal and is resistant to a wide range of chemicals and temperatures, guaranteeing consistent performance.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
12 - 35 mm
|
This seal is compatible with shafts within this diameter range, making it suitable for a variety of pump sizes and applications.
|
|
Seal Chamber Inner Diameter
|
22 - 45 mm
|
Designed to fit into seal chambers with inner diameters in this range, ensuring proper installation and optimal sealing performance.
|
|
Seal Width
|
6.5 mm
|
The 6.5 mm width is carefully calibrated to balance effective sealing and minimize frictional resistance, enhancing operational efficiency.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 1.5 MPa
|
Under normal operating conditions, the seal can withstand a maximum pressure of 1.5 MPa, preventing leakage of the pumped medium.
|
|
Working Temperature
|
-25ºC - 130ºC
|
Capable of operating effectively within this temperature range, it is suitable for both low-temperature and moderately high-temperature industrial processes.
|
|
Linear Velocity
|
Maximum 9 m/s
|
The seal can handle a maximum linear velocity of 9 m/s, ensuring stable performance even at high rotational speeds of the pump shaft.
|
|
Applicable Media
|
|
|
|
- Water-based Fluids
|
Suitable for clean water, process water, and various aqueous solutions with a pH value ranging from 2 to 12.
|
|
|
- Oil-based Fluids
|
Compatible with mineral oils, synthetic lubricants, and many common industrial oils.
|
|
|
- Chemical Fluids
|
Resistant to a wide array of chemicals, including weak acids, alkalis, and some organic solvents.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
Installed axially onto the pump shaft following a standardized procedure to ensure correct alignment and a secure seal.
|
|
Installation Torque
|
12 - 18 N·m
|
Apply a torque within this range during installation to firmly secure the seal without causing damage to its components.
|
|
Maintenance Cycle
|
Every 2500 operating hours
|
Regular maintenance every 2500 operating hours is recommended, involving inspection for signs of wear, leakage, and proper alignment.
|
|
Storage Conditions
|
Store in a dry, cool environment with a temperature between 5ºC - 25ºC. Keep away from direct sunlight and corrosive substances.
|
Proper storage helps maintain the integrity of the seal materials and extends its shelf life.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 1.8 - 2.2 years under normal operating conditions
|
With proper operation and maintenance, the QT-PTFE seal-01 can provide reliable service for 1.8 to 2.2 years.
|
|
Leakage Rate
|
≤0.07 mL/h
|
Engineered to have an extremely low leakage rate, ensuring minimal loss of the pumped medium and enhanced system efficiency.
|
|
Certification Standards
|
ISO 9001, ISO 14001
|
Meets the requirements of ISO 9001 quality management system and ISO 14001 environmental management system standards, guaranteeing high-quality and environmentally friendly production.
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 4 - 45 Hz and an amplitude of 0.35 mm.
|
Designed to maintain its sealing integrity even in environments with moderate vibration levels.
|
|
Self-lubricating Property
|
The seal surfaces are treated with a self-lubricating coating to reduce friction and wear.
|
This self-lubricating feature significantly extends the seal's service life and reduces maintenance requirements.
