Function of The Top Screw Hole of The Cartridge Mechanical Seal

1. Structure and working principle of containerized mechanical seal

Containerized mechanical seal is a sealing structure that uses spring force and ring seam surface pressure. It is widely used in various rotating equipment. Its main structure includes sealing ring, drive ring, spring and other components. When the equipment rotates, the sealing ring and the drive ring form contact to achieve the purpose of sealing.

2. Function and significance of top screw hole

The top screw hole on the containerized mechanical seal is a small hole structure, which is usually set on the sealing ring and the drive ring. Its function is to reduce the air pressure inside the seal and maintain a good contact state between the sealing ring and the drive ring. The role of the top screw hole is in the following aspects:

1. Reduce the air pressure inside the seal

Inside the mechanical seal device, due to the force between the sealing ring and the drive ring, the seal is often opened due to the squeezing of the sealing surface by high-pressure gas. The existence of the top screw hole can effectively reduce the internal pressure, so that the sealing surface is always in good condition.

2. Maintain the contact state between the sealing ring and the drive ring

Due to the structure and material of the mechanical seal device itself, the contact state between the sealing ring and the drive ring sometimes becomes loose or has a gap. The existence of the top screw hole can effectively keep the two in good contact at all times, thus achieving an ideal sealing effect.

3. Conclusion

In short, the top screw hole on the container mechanical seal is a very important auxiliary structure, which plays a vital role in the mechanical seal device. Only by fully understanding the meaning and function of the top screw hole can we better grasp the principle and application of mechanical seals and achieve the purpose of ensuring the operation of the equipment.
