Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
QT-CARTEX DN Mechanical Seal
|
A high - performance mechanical seal designed for heavy - duty industrial applications, ensuring reliable and long - lasting sealing performance.
|
|
Model
|
QT-CARTEX DN
|
Engineered to meet the stringent requirements of various pumping systems and fluid handling equipment.
|
|
Materials
|
|
|
|
- Rotating Ring
|
Silicon Carbide (SiC)
|
Offers exceptional hardness and wear resistance, enabling the rotating ring to endure high - speed and high - pressure operations without significant degradation.
|
|
- Stationary Ring
|
Carbon Graphite
|
Known for its excellent self - lubricating properties and good chemical resistance, carbon graphite provides a smooth and stable sealing surface.
|
|
- O - Ring
|
Fluoroelastomer (FKM)
|
Ensures a tight seal and is resistant to a wide range of chemicals, temperatures, and mechanical stresses, maintaining consistent performance over time.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
18 - 48 mm
|
Compatible with shafts within this diameter range, making it suitable for a variety of pump sizes in different industrial setups.
|
|
Seal Chamber Inner Diameter
|
28 - 58 mm
|
Designed to fit precisely into seal chambers with inner diameters in this range, ensuring proper installation and optimal sealing effectiveness.
|
|
Seal Width
|
7.2 mm
|
The 7.2 mm width is optimized to balance sealing efficiency and reduce frictional losses, contributing to the overall energy efficiency of the pumping system.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 1.8 MPa
|
Capable of withstanding a maximum pressure of 1.8 MPa under normal operating conditions, preventing leakage of the pumped medium.
|
|
Working Temperature
|
-30ºC - 140ºC
|
Can operate effectively within this wide temperature range, adapting to both extremely cold and moderately high - temperature industrial environments.
|
|
Linear Velocity
|
Maximum 11 m/s
|
The seal can handle a maximum linear velocity of 11 m/s, ensuring stable performance even when the pump shaft rotates at high speeds.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Suitable for fresh water, sea water, and various aqueous solutions with pH values ranging from 1.5 to 12.5.
|
|
|
- Oil - based Fluids
|
Compatible with lubricating oils, hydraulic oils, and many types of hydrocarbon - based oils.
|
|
|
- Chemical Fluids
|
Resistant to a broad spectrum of chemicals, including acids, alkalis, and solvents commonly used in industrial processes.
|
|
|
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
|
13 - 19 N·m
|
Apply a torque within this range during installation to firmly fasten the seal while avoiding damage to its components.
|
|
Maintenance Cycle
|
Every 3500 operating hours
|
Regular maintenance every 3500 operating hours is recommended, including inspection for signs of wear, leakage, and proper alignment.
|
|
Storage Conditions
|
Store in a dry, dark environment with a temperature between 8ºC - 28ºC. Keep away from direct sunlight and any sources of chemical fumes.
|
Proper storage helps maintain the integrity of the seal materials and extends its service life.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 2 - 3 years under normal operating conditions
|
With proper operation and maintenance, the QT-CARTEX DN seal can provide reliable service for 2 - 3 years.
|
|
Leakage Rate
|
≤0.06 mL/h
|
Engineered to have an extremely low leakage rate, ensuring minimal loss of the pumped medium and enhanced system reliability.
|
|
Certification Standards
|
ISO 9001, ISO 14001, ISO 44001
|
Meets the requirements of multiple international standards, guaranteeing high - quality production, environmental sustainability, and effective supply chain management.
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 3 - 50 Hz and an amplitude of 0.4 mm.
|
Designed to maintain its sealing performance even in environments with significant vibration levels.
|
|
Self - lubricating Property
|
The seal surfaces are designed with self - lubricating features, reducing friction and wear, and minimizing the need for external lubrication.
|
This property contributes to the extended service life and reduced maintenance costs of the seal.
