Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
QT BEL03 - 101 Mechanical Seal
|
A specialized mechanical seal designed for high - performance applications, providing reliable sealing solutions across various industrial scenarios.
|
|
Model
|
QT BEL03 - 101
|
Engineered with advanced technology to offer excellent durability and efficiency in sealing operations.
|
|
Materials
|
|
|
|
- Rotating Ring
|
Silicon Carbide (SiC)
|
The rotating ring made of silicon carbide features high hardness and outstanding wear resistance, enabling it to withstand intense friction and high - speed rotations, thus ensuring a long service life.
|
|
- Stationary Ring
|
Carbon Graphite
|
Carbon graphite is used for the stationary ring due to its self - lubricating properties and good chemical resistance, which contribute to smooth operation and effective sealing.
|
|
- O - Ring
|
Fluoroelastomer (FKM)
|
The FKM O - ring provides a tight and reliable seal, resistant to a wide range of chemicals and temperature fluctuations, maintaining consistent performance.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
18 - 35 mm
|
Suitable for installation on shafts with diameters within this range, making it compatible with numerous pump models and sizes.
|
|
Seal Chamber Inner Diameter
|
28 - 45 mm
|
Designed to fit precisely into seal chambers with inner diameters in this range, ensuring proper installation and optimal sealing performance.
|
|
Seal Width
|
6 mm
|
The 6 - mm seal width is carefully optimized to balance sealing effectiveness and minimize energy consumption caused by friction.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 1.5 MPa
|
Under normal operating conditions, the seal can endure a maximum pressure of 1.5 MPa, effectively preventing leakage of the pumped medium.
|
|
Working Temperature
|
-20ºC - 150ºC
|
Capable of operating efficiently within this temperature range, making it suitable for applications in both cold and moderately high - temperature environments.
|
|
Linear Velocity
|
Maximum 9 m/s
|
The seal can handle a maximum linear velocity of 9 m/s, ensuring stable operation even at relatively high rotational speeds of the pump.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Ideal for use with clean water, treated water, and various aqueous solutions with a pH value between 4 - 12.
|
|
|
- Oil - based Fluids
|
Compatible with common lubricating oils, gear oils, and many hydraulic oils.
|
|
|
- Chemical Fluids
|
Resistant to a variety of mild acids, alkalis, and some organic solvents, but specific compatibility should be confirmed based on actual media composition.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
Installed axially onto the pump shaft following a strict installation procedure to ensure accurate alignment and a tight seal.
|
|
Installation Torque
|
12 - 16 N·m
|
During installation, a torque within this range should be applied to secure the seal properly without causing damage to the components.
|
|
Maintenance Cycle
|
Every 3500 operating hours
|
Regular maintenance every 3500 operating hours is recommended, including inspection for signs of wear, leakage, and component integrity.
|
|
Storage Conditions
|
Store in a dry, shaded place with a temperature range of 8ºC - 22ºC. Keep away from direct sunlight, humidity, and corrosive gases.
|
Proper storage conditions help preserve the quality and performance of the seal, preventing premature deterioration.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 1.8 - 2.8 years under normal operating conditions
|
With proper operation and regular maintenance, the QT BEL03 - 101 seal can provide reliable service for 1.8 to 2.8 years.
|
|
Leakage Rate
|
≤0.1 mL/h
|
Engineered to have a low leakage rate, ensuring minimal loss of the pumped medium and maintaining system efficiency.
|
|
Certification Standards
|
ISO 9001, ISO 14001
|
Meets the requirements of ISO 9001 quality management system standards and ISO 14001 environmental management system standards.
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 8 - 55 Hz and an amplitude of 0.5 mm.
|
Designed to maintain its sealing performance in environments with moderate vibration levels.
|
|
Self - lubricating Property
|
The seal faces are coated with a self - lubricating layer, reducing friction and wear during operation.
|
This self - lubricating feature extends the seal's lifespan and improves its overall operational efficiency.
