Design Features:
1. Dual-End Face and Buffer Solution Design: Features two pairs of sealing ends and requires a buffer solution. This design provides double sealing protection, effectively preventing media leakage. The buffer solution lubricates, cools, and balances pressure between the sealing ends, reducing end face wear and extending seal life.
2. Balanced Structure Advantages: The balanced design automatically balances media pressure, reducing the specific pressure of the sealing ends. This allows the seal to maintain good sealing performance even under high-pressure conditions, reducing power consumption and heat generation, and improving seal reliability.
3. Flexible Compensation with Multi-Spring Components: Utilizing multi-spring components, the spring force is evenly distributed, enabling precise and flexible compensation for wear on the sealing ends, maintaining good sealing contact and ensuring stable sealing performance.
4. Spring Rotation and Ear-Shaped Drive: The spring rotation structure ensures uniform force distribution on the springs during equipment operation, reducing stress concentration. The ear-shaped drive ensures reliable connection and power transmission between the seal and the rotating shaft, allowing the seal to operate stably and synchronously with the shaft’s rotation.
5. Distributed flushing for effective cleaning: The distributed flushing system evenly delivers flushing fluid to the sealing area, promptly removing impurities and heat from the sealing face, maintaining cleanliness and good lubrication, and improving the seal’s anti-clogging and heat dissipation capabilities.
6. Self-circulating buffer ensures stability: The self-circulating buffer design allows the buffer solution to automatically circulate within the sealing system, continuously performing its lubrication, cooling, and pressure balancing functions without an external power source, ensuring stable operation of the sealing system under various working conditions.
Operating Parameters:
- Wide Temperature Range: Stable operation within a temperature range of -40℃ to 260℃ (depending on material selection), maintaining good sealing performance in both low-temperature liquefied gas environments and high-temperature process conditions, meeting the needs of various complex operating conditions.
- Flexible Pressure Adaptability: Capable of withstanding pressures from 0 to 3.0 MPa, adapting to pressure variations in different equipment, ensuring effective sealing under various pressure conditions and preventing media leakage.
- Strong Speed Adaptability: Suitable for operating conditions at speeds of 3600 rpm or 25 m/s, it can match the speeds of various rotating equipment, ensuring stable and reliable sealing even during high-speed rotation.
Standards and Product Advantages:
- Strict Standard Adherence: Adheres to industry standards such as API682 and JB/T4127.1, ensuring that the product’s design, manufacturing, and performance meet relevant international and domestic specifications, guaranteeing product quality and reliability.
- Pressureless Double Seal Advantage: As a pressureless double seal, it is the preferred sealing form for flammable and explosive media. It effectively prevents media leakage into the atmosphere, ensuring the safety of the production environment and personnel. Simultaneously, the buffer tank is typically connected to the torch system, further ensuring the safe handling of any potential minor leaks.
- Standard Layout Compliance: Complies with AP1682 standard layout mode 2 (2CW-CW), offering good versatility and interchangeability, facilitating equipment installation, maintenance, and upgrades.
Applications:
Widely used in pumps for light hydrocarbons, aromatics, acetic acid, etc., in the petrochemical and coal chemical industries, as well as other rotating equipment. In industries with extremely high sealing requirements, mechanical seals, with their superior performance and reliable quality, provide strong support for the stable operation of equipment and are important components for ensuring production safety and improving production efficiency.
