A108-45 Mechanical seal of stator cooling water pump

Short Description:

A108-45 mechanical seal belongs to the spare parts of stator cooling water pump YCZ65-250C. The mechanical seal relies on one or several pairs of end faces that are perpendicular to the shaft for relative sliding under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism. Combined with the auxiliary seal to prevent leakage of the shaft seal device.

Mechanical seal of stator cooling water pump

Mechanical Seal Of Stator Cooling Water Pump:

The commonly used mechanical seal structure is composed of static ring (static ring), rotating ring (moving ring), elastic element spring seat, set screw, rotating ring auxiliary sealing ring and stationary ring auxiliary sealing ring. Cover to prevent stationary ring from rotating. Rotating and stationary rings are also often referred to as compensated or non-compensated rings depending on whether they have axial compensation capabilities.

The pump spare parts, A108-45 mechanical seal is composed of spring, fork groove transmission, rotating ring, stationary ring, sealing material, etc. The sealing ring can choose different sealing material according to different working conditions, and the temperature can be from -70 to 250 ℃.

There is a 3*10° chamfer on the shoulder of the shaft or shaft sleeve where the A108-45 mechanical seal is installed, and the chamfer and burr should be removed from the end of the sealing ring seat hole of the sealing gland. When installing the mechanical seal, it is necessary to check the surface quality of each part, especially whether the sealing ends of the dynamic and static rings have bumps, scratches, etc. If there is any damage, it must be repaired or replaced. Apply a layer of oil to the sealing end faces of the dynamic and static rings.
