Parameters of Outflow Bellows Mechanical Seal:

The external flow bellows mechanical seal and the effective diameter of the bellows under internal pressure are shown in Figure 1-6.

Figure 1-6 External flow bellows mechanical seal and the effective diameter of the bellows under internal pressure

The effective area Ae of the bellows mechanical seal is

For internal flow

For outflow

The fluid pressure acts on the compensation ring to make it close to the non-compensation ring. The ratio of the effective area inflammation to the nominal contact area A of the sealing surface is the load factor K (that is, the area ratio B), which reflects the sealing end Carrying capacity, namely

For the internal flow type mechanical seal and the external flow type mechanical seal, the effective area of u200bu200bthe fluid action is different. Let A1 and A2 be the effective area of u200bu200bthe external flow type mechanical seal and the internal flow type mechanical seal.

Load factor K (area ratio B) of internal flow mechanical seal

Load factor K of outflow mechanical seal (face ratio B)
