Non-assembly mechanical seals 

1. To assemble mechanical seal static component into the pump cavity gland.

2. When the mechanical seal using V-ring structure, in the installation of special attention to its V-shaped openings must face the medium (or sealing fluid) pressure direction.

3.The mechanical seal components set on the pump shaft (also must make the V-type openings facing the pressure direction) according to the model specification to determine the position of the spring seat and according to the requirements of the adjustment, so that the spring pressure to meet the design requirements. thus ensuring the normal working pressure of the sealing surface. Tighten the screws evenly.

4.The installation of one-way rotation (that is, the loop or hook spring transmission) mechanical seals, especially attention to the spring rotation, its rotation should be the same as the axis rotation direction, so that the spring more tightly. From the mechanical seal to the end of the static ring to see, to determine the rotation direction of the axis, clockwise direction for the right, counterclockwise direction for the left rotation

Second, operation and precautions

1. Mechanical seals was absolutely not allowed dry turn ,the pump must be fully vented before the device starts, so that the media is filled with sealed cavities before the device can be opened. 

2. The operation of equipment should strictly follow the following procedures:

3. Before the equipment operation, should start flushing water, 5 minutes later, start the mainframe;

4. If you do not open flushing water, will lead to sealing surface dry friction, high temperature, seal ring burnout and seal ring coking, which will lead to complete failure of the seal. The phenomenon is more prominent in the two-terminal and multi-faceted structures.

5. In the operation of equipment, should always check whether the flushing water is unblocked, pressure to meet the requirements;During operation, flushing water cannot be interrupted or stopped.
