Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
CR - 3R Mechanical Seal
|
A high - performance mechanical seal meticulously designed for a wide range of industrial pumps, ensuring reliable and efficient operation.
|
|
Brand
|
[Insert Brand Name]
|
|
|
Model
|
CR - 3R
|
This model is engineered to meet the demanding requirements of various industrial applications, providing stable sealing performance.
|
|
Materials
|
|
|
|
- Rotating Ring
|
Tungsten Carbide
|
Tungsten carbide offers exceptional hardness and wear resistance, enabling the rotating ring to endure high - speed and high - pressure conditions, thus extending the seal's service life.
|
|
- Stationary Ring
|
Silicon Carbide (SiC)
|
The silicon carbide stationary ring provides excellent corrosion resistance and a smooth surface finish, which are essential for effective sealing.
|
|
- O - Ring
|
Ethylene Propylene Diene Monomer (EPDM)
|
The EPDM O - ring ensures a tight seal and demonstrates good resistance to water, steam, and a variety of chemicals, contributing to the overall reliability of the seal.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
12 - 35 mm
|
This seal is compatible with pump shafts within this diameter range, making it suitable for a diverse selection of pump models.
|
|
Seal Chamber Inner Diameter
|
22 - 45 mm
|
Designed to fit precisely into seal chambers with inner diameters in this range, guaranteeing proper installation and optimal performance.
|
|
Seal Width
|
6.5 mm
|
The 6.5 mm width of the seal is optimized to strike a balance between achieving effective sealing and minimizing frictional losses.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 1.5 MPa
|
Under normal operating conditions, the CR - 3R seal can withstand a maximum pressure of 1.5 MPa, effectively preventing the leakage of the pumped medium.
|
|
Working Temperature
|
-30ºC - 130ºC
|
Capable of operating efficiently within this wide temperature range, it is suitable for applications involving both extremely cold and moderately high - temperature environments.
|
|
Linear Velocity
|
Maximum 9 m/s
|
The seal is engineered to handle a maximum linear velocity of 9 m/s, ensuring stable performance even at high rotational speeds of the pump.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Suitable for pure water, process water, and water - based solutions with a pH value ranging from 4 to 10.
|
|
|
- Oil - based Fluids
|
Compatible with mineral oils, synthetic lubricants, and certain types of hydraulic oils.
|
|
|
- Chemical Fluids
|
Resistant to mild acids, alkalis, and some organic solvents, depending on the concentration and operating conditions.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
The seal is installed axially onto the pump shaft following a standardized installation procedure to ensure accurate alignment and a secure seal.
|
|
Installation Torque
|
8 - 12 N·m
|
During installation, applying a torque within this range secures the seal in place without causing damage due to over - tightening.
|
|
Maintenance Cycle
|
Every 2500 operating hours
|
Regular maintenance is recommended every 2500 operating hours. This includes inspecting the seal for signs of wear, leakage, and proper alignment.
|
|
Storage Conditions
|
Store in a dry, dust - free environment with a temperature between 5ºC - 25ºC. Keep away from direct sunlight and strong magnetic fields.
|
Proper storage conditions help preserve the integrity of the seal components and prevent premature deterioration.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 1.8 - 2.2 years under normal operating conditions
|
With proper operation and maintenance, the CR - 3R seal can provide reliable service for 1.8 to 2.2 years.
|
|
Leakage Rate
|
≤0.06 mL/h
|
Engineered to have an extremely low leakage rate, the seal ensures that the pumped medium remains contained within the system, enhancing operational safety and efficiency.
|
|
Certification Standards
|
ISO 9001, ISO 14001
|
The CR - 3R seal complies with ISO 9001 quality management system standards and ISO 14001 environmental management system standards, demonstrating its commitment to quality and environmental sustainability.
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 3 - 35 Hz and an amplitude of 0.3 mm.
|
Designed to maintain its sealing performance even in environments with moderate levels of vibration, ensuring stable operation of the pump.
|
|
Self - lubricating Property
|
The seal surfaces are treated with a special self - lubricating coating to reduce friction and wear.
|
This self - lubricating feature not only extends the service life of the seal but also reduces the energy consumption associated with frictional forces.
