Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
QT-M3N Mechanical Seal
|
A high - performance mechanical seal meticulously designed for a wide range of industrial pumping applications, ensuring reliable and efficient operation.
|
|
Brand
|
[Brand Name]
|
|
|
Model
|
QT-M3N
|
This model is engineered to meet the demanding requirements of various working conditions, providing stable sealing performance.
|
|
Materials
|
|
|
|
- Rotating Ring
|
Tungsten Carbide
|
Tungsten carbide offers extreme hardness and superior wear resistance, enabling the rotating ring to withstand high - speed and high - pressure operations, thus extending the overall lifespan of the seal.
|
|
- Stationary Ring
|
Carbon Graphite
|
Carbon graphite is chosen for its excellent self - lubricating properties and good chemical resistance, which helps in creating a smooth sealing surface and reducing friction.
|
|
- O - Ring
|
Fluoroelastomer (FKM)
|
The FKM O - ring provides a tight and reliable seal, with resistance to a broad spectrum of chemicals and temperature variations, ensuring consistent performance.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
25 - 55 mm
|
The seal is compatible with pump shafts having diameters within this range, making it suitable for a diverse array of pump sizes and types.
|
|
Seal Chamber Inner Diameter
|
35 - 65 mm
|
Designed to fit precisely into seal chambers with inner diameters falling in this interval, guaranteeing proper installation and optimal functionality.
|
|
Seal Width
|
9 mm
|
The 9 - mm seal width is carefully calibrated to strike a balance between effective sealing and minimizing energy - consuming friction.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 2.0 MPa
|
Under normal operating circumstances, the seal can endure a maximum pressure of 2.0 MPa, effectively preventing leakage of the pumped medium.
|
|
Working Temperature
|
-30ºC - 180ºC
|
Capable of operating efficiently within this extensive temperature range, it is adaptable to both extremely cold and relatively high - temperature industrial environments.
|
|
Linear Velocity
|
Maximum 12 m/s
|
The seal is engineered to handle a maximum linear velocity of 12 m/s, ensuring stable performance even in high - speed rotating pumps.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Suitable for potable water, industrial process water, and water - based solutions with a pH range of 2 - 13, demonstrating good chemical compatibility.
|
|
|
- Oil - based Fluids
|
Applicable to mineral oils, synthetic lubricants, and certain petroleum - based products, ensuring reliable operation in oil - handling systems.
|
|
|
- Chemical Fluids
|
Can be used with common acids (such as diluted sulfuric acid), alkalis, and some organic solvents, subject to specific concentration limits.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
Installed axially onto the pump shaft following a standardized procedure, which includes proper alignment and tightening to ensure a secure and leak - free fit.
|
|
Installation Torque
|
18 - 23 N·m
|
During installation, a torque within this range should be applied to firmly secure the seal without causing damage to its components.
|
|
Maintenance Cycle
|
Every 4000 operating hours
|
Regular maintenance is recommended every 4000 operating hours. This involves inspecting the seal for signs of wear, checking for any leakage, and ensuring proper alignment of the seal components.
|
|
Storage Conditions
|
Store in a dry, dust - free environment with a temperature range of 5ºC - 25ºC. Avoid exposure to direct sunlight and strong electromagnetic fields.
|
Proper storage conditions help preserve the integrity of the seal materials and prevent premature aging or degradation.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 2 - 3.5 years under normal operating conditions
|
With proper operation and regular maintenance, the QT - M3N seal can provide reliable service for 2 - 3.5 years, offering a long - term sealing solution.
|
|
Leakage Rate
|
≤0.05 mL/h
|
Engineered to have an extremely low leakage rate, the seal ensures minimal loss of the pumped medium, enhancing the efficiency and safety of the pumping system.
|
|
Certification Standards
|
ISO 9001, ISO 14001, and API 682 (Type B)
|
The seal complies with international quality management (ISO 9001), environmental management (ISO 14001) standards, and meets the requirements of API 682 (Type B) for mechanical seals in petroleum, petrochemical, and chemical industries.
|
|
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 integrity even in environments with significant vibrations, ensuring stable operation of the pumping system.
|
|
Self - lubricating Property
|
The mating surfaces of the seal are treated with a special coating to enhance self - lubrication, reducing friction and wear.
|
This self - lubricating feature not only extends the service life of the seal but also reduces energy consumption during operation.
