Structural features

1. The structure is a double-face balanced mechanical seal with a step on the shaft sleeve. The axial dimension of the mechanical seal should be strictly controlled when the pump chamber is installed.

2. The sealing device is equipped with a pressure gauge, which can conveniently measure the blocking water pressure and avoid premature failure of the mechanical seal due to the lack or insufficiency of the blocking water.

3. The flushing water can be recycled and does not enter the media process, and has no effect on the technological process.

Directions

1. One end of the pressure gauge is connected with the blocking water outlet through the tee junction, and the other end is connected with the blocking water inlet through the valve.

2. The sealing pressure should be higher than that of the sealing chamber pressure 0.1-0.2Mpa.

3. Before the pump starts, you need to open the sealing water 5 minutes in advance. When the pump is stopped, the sealing water must be closed after 5 minutes.

4. The flushing water must be kept stable and continuous during the operation of the pump.
