Mechanical seal structure and working principle of batch reactor

The batch reactor has a relative rotation seal between the stationary ring and the moving ring, which belongs to the dynamic seal and relies on the spring loading device and the medium pressure to rotate relative to each other. A suitable pressing force is generated on the contact surface (end surface) between the stationary ring and the moving ring, so that the two smooth and straight end faces are closely fitted, and a very thin fluid is maintained between the end faces for sealing purposes.

The mechanical seal in the batch reactor consists of a spring loading device, a moving ring, a static ring and an auxiliary sealing ring.

Mechanical seals in batch reactors typically have four working faces:

1. The seal between the static ring and the static ring seat of the enamel reactor is the static seal of the reaction kettle. Generally, an elastic auxiliary seal ring is used to prevent leakage.

2, the seal between the static ring seat of the enamel reactor and the equipment is also the static seal of the reaction kettle, which can be sealed by using ordinary gaskets.

3. The seal between the moving ring of the enamel reactor and the shaft (sleeve), which is also a relatively static seal, usually sealed with a 0-ring.

The above three are all static seals, which can be used to prevent leakage.

4 The enamel reactor is relatively rotating and sealed between the static ring and the moving ring. It belongs to the dynamic seal and relies on the spring loading device and the medium pressure to rotate relative to each other. A suitable pressing force is generated on the contact surface (end surface) between the stationary ring and the moving ring, so that the two smooth and straight end faces are closely fitted, and a very thin fluid is maintained between the end faces for sealing purposes.
