notes:

Mechanical seal precision parts, during the installation process, do not smash the sealing element!

Non-assembled mechanical seal

1. Assemble the static part of the mechanical seal into the pump chamber gland.

2. When the mechanical seal adopts a V-shaped ring structure, special attention should be paid to the V-shaped opening must face the pressure direction of the medium (or sealing fluid) during installation.

3. The mechanical seal element set on the pump shaft (the V-shaped hole must also face the direction of pressure) determines the position of the spring seat according to the model specification and adjusts it as required to make the spring pressure meet the design requirements. So as to ensure the normal working pressure of the sealing surface. Tighten the screws evenly.

4. Install the mechanical seal with one-way rotation (that is, ring or hook spring transmission), especially pay attention to the rotation of the spring, and its rotation direction should be consistent with the rotation direction of the shaft to make the spring tighter. From the mechanical seal to the end of the static ring, judge the rotation direction of the shaft, clockwise is right, counterclockwise is left

2. Operation and Precautions

1. The mechanical seal is absolutely not allowed to run dry. Before the equipment is started, the pump must be completely emptied so that the medium is filled with the sealing chamber before the equipment can be opened.

2. The operation of the equipment should be carried out in strict accordance with the following procedures:

3. Before the equipment is running, the flushing water should be started, and after 5 minutes, the host should be started;

4. If the flushing water is not turned on, it will cause dry friction of the sealing surface, high temperature, burning of the sealing ring and coking of the sealing ring, resulting in complete failure of the seal. This phenomenon is more prominent in two-ended and faceted structures.

5. During the operation of the equipment, it should be checked frequently whether the flushing water is unblocked and whether the pressure meets the requirements; during the operation, the flushing water cannot be interrupted or stopped.

6. The best operation mode of the pump is to work continuously. If it must be shut down, the return sediment in the pipeline and pump chamber should be flushed. If you want to stop, you must first stop for 5 minutes and then flush the water can be turned off
