Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT-QL60 Lower Seal	A specialized mechanical seal designed for the lower part of specific industrial equipment, ensuring reliable sealing performance in demanding operating conditions.
Brand	[Brand Name] (replace as per actual)
Model	QT-QL60	This model is engineered to meet the high - performance requirements of various applications, providing consistent and efficient sealing.
Materials
- Rotating Ring	Tungsten Carbide	Tungsten carbide offers exceptional hardness and wear resistance, enabling the rotating ring to endure high - speed and high - pressure operations, thus extending the seal's service life.
- Stationary Ring	Silicon Nitride	Silicon nitride has excellent chemical stability and a smooth surface, which is crucial for achieving effective and long - lasting sealing.
- O - Ring	Fluoroelastomer (FKM)	The FKM O - ring provides a tight seal and shows good resistance to a wide range of chemicals and temperature variations, ensuring reliable operation.
Size Specifications
Shaft Diameter Range	30 - 60 mm	This seal can be installed on shafts with diameters within this range, making it suitable for a variety of equipment shaft sizes.
Seal Chamber Inner Diameter	40 - 70 mm	Specifically designed to fit into seal chambers with inner diameters in this range, ensuring proper installation and optimal performance.
Seal Width	9 mm	The 9 - mm width of the seal is optimized to balance between effective sealing and minimizing friction, contributing to its overall efficiency.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operating conditions, the seal can withstand a maximum pressure of 2.0 MPa, effectively preventing the leakage of the pumped medium.
Working Temperature	-25ºC - 180ºC	Capable of operating efficiently within this wide temperature range, making it suitable for both extremely cold and high - temperature industrial applications.
Linear Velocity	Maximum 12 m/s	The seal is designed to handle a maximum linear velocity of 12 m/s, ensuring stable performance even at high rotational speeds.
Applicable Media
- Water - based Fluids	Suitable for clean water, industrial wastewater, and water - based solutions with a pH value ranging from 2 to 13.
- Oil - based Fluids	Applicable to lubricating oils, gear oils, and certain petroleum - based fluids.
- Chemical Fluids	Can be used with mild acids, alkalis, and some organic solvents, depending on the specific concentration and operating conditions.
Installation and Maintenance
Installation Method	Axial Installation with Centering Tool	Installed axially onto the shaft using a centering tool to ensure precise alignment, which is essential for proper sealing. The installation process should follow the provided detailed instructions.
Installation Torque	18 - 22 N·m	During installation, a torque within this range should be applied to secure the seal firmly without causing damage to its components.
Maintenance Cycle	Every 4000 Operating Hours	Regular maintenance is recommended every 4000 operating hours. This includes inspecting the seal for signs of wear, leakage, and proper alignment, as well as cleaning and lubricating relevant parts if necessary.
Storage Conditions	Store in a dry, dust - free environment at a temperature between 5ºC - 25ºC. Avoid exposure to direct sunlight, moisture, and corrosive gases.	Proper storage conditions help maintain the integrity of the seal components and prevent premature aging or damage.
Quality and Certification
Service Life	Approximately 2 - 3.5 years under normal operating conditions	With proper operation and regular maintenance, the QT-QL60 Lower Seal can provide reliable service for 2 to 3.5 years.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate, ensuring that the sealed medium remains within the system, enhancing safety and efficiency.
Certification Standards	ISO 9001, ISO 14001, and industry - specific certifications (e.g., API 682 for relevant applications)	The seal complies with international quality management and environmental management system standards, as well as relevant industry - specific requirements, guaranteeing its high quality and reliability.
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 performance even in environments with significant vibrations, ensuring stable operation of the equipment.
Self - lubricating Property	The seal faces are treated with a self - lubricating coating	This self - lubricating feature reduces friction between the seal faces, minimizing wear and extending the service life of the seal, while also reducing the need for additional lubrication.
