| Model Number |
QT - 886HT |
| Application |
Widely used in various industrial equipment, such as pumps, compressors, and mixers, to prevent leakage of fluids and ensure the normal operation of the equipment. |
| Operating Temperature Range |
-20°C to 180°C. This wide temperature range allows the mechanical seal to work effectively in different environments, whether it is in a relatively cold storage area or a high - temperature industrial process. |
| Pressure Resistance |
Can withstand a maximum pressure of 10 MPa. This high - pressure resistance ensures that the seal can maintain its integrity and sealing performance even under high - pressure conditions, preventing fluid leakage due to pressure changes. |
| Shaft Size Compatibility |
Compatible with shaft diameters ranging from 20 mm to 100 mm. This wide range of shaft size compatibility makes it suitable for a variety of equipment with different shaft specifications. |
| Material of Primary Sealing Faces |
The primary sealing faces are made of high - quality ceramic and carbon materials. The ceramic material provides excellent hardness and wear resistance, while the carbon material offers good self - lubrication and low friction coefficient, which together ensure a long - lasting and effective sealing performance. |
| Secondary Sealing Material |
A special synthetic rubber material is used for the secondary sealing. This material has good elasticity, chemical resistance, and weather resistance, which can effectively prevent the penetration of fluids from the side and ensure the overall sealing effect. |
| Chemical Resistance |
Resistant to a wide range of chemicals, including acids, alkalis, and organic solvents. This chemical resistance makes it suitable for use in chemical processing plants, food and beverage industries, and other fields where contact with various chemicals is common. |
| Rotation Speed |
Can operate at a maximum rotation speed of 3000 rpm. This high - speed adaptability allows it to be used in high - speed rotating equipment without sacrificing sealing performance. |
| Installation Method |
It is designed for easy installation. The seal can be installed either in a cartridge form or as individual components, depending on the specific requirements of the equipment. This flexibility in installation methods makes it convenient for maintenance and replacement. |
| Surface Finish |
The sealing surfaces have a very smooth finish, with a surface roughness of Ra ≤ 0.2μm. This smooth surface finish reduces friction and wear during operation, and also helps to improve the sealing performance by minimizing the gap between the sealing faces. |
| Axial Movement Tolerance |
Can tolerate an axial movement of ± 0.5 mm. This tolerance allows for some axial displacement of the shaft during operation without affecting the sealing performance, ensuring the stability of the equipment. |
| Radial Runout Tolerance |
Can tolerate a radial runout of ± 0.1 mm. This tolerance ensures that the seal can still work effectively even when there is a certain degree of radial deviation of the shaft, which is common in some industrial equipment due to manufacturing and installation errors. |
| Service Life |
Under normal operating conditions, the expected service life of the QT - 886HT mechanical seal is at least 2 years. However, this can be affected by factors such as operating conditions, fluid properties, and maintenance frequency. |
| Maintenance Requirements |
Regular inspection and cleaning are recommended to ensure the long - term performance of the seal. It is also necessary to replace the secondary sealing material periodically according to the operating conditions. |
| Certification |
The product meets relevant international standards and has obtained certifications such as ISO 9001, which ensures its quality and reliability. |
