The 109 series mechanical seal is a well-designed and reliable universal sealing component. With a reasonable structural design and high-quality material selection, it has become the preferred product for fluid seals in the industrial field. This series adopts an interior, single end face, single spring, and unbalanced structure, with specifications covering 10-110mm, suitable for various rotating mechanical equipment, and can flexibly cope with water, oil, and general corrosive solutions. The special material version can withstand strong acid, alkali, and chlorine corrosion, and the sealing effect is stable.
The production of the product relies on advanced CNC machining equipment and strictly follows precision manufacturing processes. The sealing end face is professionally ground and processed, and the corrugated tube is processed through multiple steps of quenching. The assembly process is rigorous and standardized, and the finished product passes the full process quality inspection. The quality meets international standards, and the dynamic ring can be flexibly changed in material. It is easy to install, has low maintenance costs, and can achieve stable transmission without bonding.
As a widely used universal mechanical seal, the 109 series has been deeply adapted to multiple industries such as papermaking, chemical, power, metallurgy, and cement. It can be used for various pump bodies such as water pumps, sewage pumps, chemical pumps, pulp pumps, as well as mixers, centrifuges, and other equipment, effectively solving the problem of fluid leakage, reducing equipment losses, and improving operational efficiency. It has the advantages of strong adaptability, good sealing performance, and long service life, which can meet the complex sealing needs of different industries and provide reliable guarantee for the stable operation of industrial production. It is a cost-effective universal mechanical seal product.
Product Production Process
1. Core process: Relying on advanced CNC machine tools and CNC machining centers, following the five major links of raw material selection, precision machining, sealing surface grinding, assembly and debugging, and full process quality inspection.
2. Raw material processing: Strictly screen the raw materials before entering the site to ensure that the material performance meets the standards.
3. Key processing: The sealing end face adopts professional grinding technology to improve flatness and smoothness; The corrugated pipe adopts processes such as stamping, cleaning, welding, and heat treatment, while the PTFE corrugated pipe adopts a single blade turning process.
4. Assembly requirements: The parts should be cleaned and pre-treated with alcohol or specialized cleaning agents, and operated according to the static ring installation, dynamic ring and shaft sleeve assembly, and overall assembly process to ensure that the springs are concentric and the sealing surface is evenly stressed.
5. Quality inspection standards: The finished product undergoes multiple performance tests such as high temperature resistance, sealing, and corrosion resistance. Dimensional testing is carried out using tools such as coordinate measuring instruments and micrometers. Surface quality is verified through optical microscopy, and the entire process is traceable.
Features
1. Structural design: Interior, internal flow, single end face, single spring, unbalanced structure, overall exquisite and reasonable, highly adaptable.
2. Specification range: The specification covers 10-110mm and can meet the sealing requirements of different equipment.
3. Material selection: The sealing end face is made of high-quality materials such as graphite, silicon carbide, and hard alloy, and the auxiliary sealing is made of elastic materials such as nitrile, ethylene propylene, and fluorine rubber. Metal components are made of corrosion-resistant materials such as 304, 316L stainless steel, and Hastelloy C.
4. Performance parameters: Can withstand temperature range of -20℃ to 300℃, working pressure ≤ 1.2MPa, linear velocity ≤ 10m/s, axial displacement ± 0.5mm.
5. Compatible media: Suitable for water, oil, and general corrosive solutions. Some special materials are resistant to strong acid, alkali, and chlorine corrosion.
6. Other advantages: The rubber corrugated tube has both secondary sealing and dynamic ring driving functions. The dynamic ring is driven by an L-ring and a spring, without the need for bonding, and can be flexibly changed in material. It is easy to install and has low maintenance costs. The quality meets DIN24960 and ISO9001:2000 standards, and the sealing performance is stable and reliable.
