Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
Queeny-John Crane type 9 Mechanical Seal
|
A high - performance mechanical seal developed by Queeny in collaboration with John Crane, designed for demanding industrial applications
|
|
Brand
|
Queeny-John Crane
|
|
|
Model
|
type 9
|
This model is engineered to offer superior sealing performance in various fluid handling systems
|
|
Materials
|
|
|
|
- Rotating Ring
|
Tungsten Carbide (WC)
|
Tungsten carbide provides excellent hardness and wear resistance, enabling the rotating ring to withstand high - speed and high - pressure operations with minimal degradation
|
|
- Stationary Ring
|
Silicon Carbide (SiC)
|
The silicon carbide stationary ring offers high corrosion resistance and a smooth surface finish, ensuring efficient sealing and long - term reliability
|
|
- O - Ring
|
Fluoroelastomer (FKM)
|
The FKM O - ring provides a tight seal and is resistant to a wide range of chemicals and temperatures, maintaining its integrity under harsh operating conditions
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
25 - 60 mm
|
Suitable for installation on pump shafts with diameters within this range, covering a broad spectrum of industrial pump sizes
|
|
Seal Chamber Inner Diameter
|
35 - 70 mm
|
Designed to fit into seal chambers with inner diameters in this range for proper installation and optimal performance
|
|
Seal Width
|
9 mm
|
The 9 - mm width is optimized to balance sealing effectiveness and mechanical stability, reducing the risk of leakage and premature wear
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 2.0 MPa
|
Under normal operating conditions, the seal can withstand a maximum pressure of 2.0 MPa, ensuring reliable containment of the pumped fluid
|
|
Working Temperature
|
-25ºC - 180ºC
|
Capable of operating effectively within this wide temperature range, making it suitable for both cryogenic and high - temperature applications
|
|
Linear Velocity
|
Maximum 12 m/s
|
The seal is designed to handle a maximum linear velocity of 12 m/s, enabling it to function efficiently in high - speed rotating equipment
|
|
Applicable Media
|
|
|
|
- Chemical Fluids
|
Compatible with acids (pH 1 - 5), alkalis (pH 9 - 14), and various organic solvents, excluding highly aggressive fluorinated compounds
|
|
|
- Petroleum - based Fluids
|
Suitable for use with crude oil, refined oils, and petroleum derivatives, providing reliable sealing in the oil and gas industry
|
|
|
- Food - grade Fluids
|
Meets hygiene standards for use in food and beverage processing, with materials compliant with relevant food safety regulations
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation with Centering Guides
|
Installed axially onto the pump shaft using centering guides to ensure precise alignment and proper seating of the seal components
|
|
Installation Torque
|
18 - 22 N·m
|
Apply a torque within this range during installation to secure the seal firmly while avoiding damage to the delicate seal faces
|
|
Maintenance Cycle
|
Every 4000 operating hours or 6 months (whichever comes first)
|
Regular maintenance includes visual inspection of the seal for signs of wear, leakage, and damage, as well as checking the alignment and lubrication of the pump shaft
|
|
Storage Conditions
|
Store in a dry, dust - free environment at temperatures between 5ºC - 25ºC. Avoid exposure to direct sunlight, moisture, and corrosive gases
|
Proper storage conditions help preserve the seal's material properties and extend its shelf life
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 2 - 3 years under normal operating conditions
|
With proper operation and maintenance, the Queeny-John Crane type 9 seal can provide reliable service for an extended period
|
|
Leakage Rate
|
≤0.05 mL/h
|
Engineered to have an extremely low leakage rate, minimizing fluid loss and ensuring environmental compliance
|
|
Certification Standards
|
ISO 9001, ISO 14001, API 682 (Level 3)
|
Meets international quality management, environmental management, and industry - specific sealing standards for enhanced credibility and performance assurance
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 10 - 60 Hz and an amplitude of 0.6 mm without compromising sealing performance
|
|
|
Self - aligning Feature
|
The seal design incorporates a self - aligning mechanism that compensates for minor misalignments of the pump shaft, reducing stress on the seal faces and extending its service life
