1、關于外沖刷機封的冷卻水的壓力不宜過大，一般情況不高于0.05MPa，流量0.3L/S左右，一般能自然活動即可。
　　2、關于內沖刷機封的冷卻水的壓力應比密封腔內的工作壓力高0.1MPa以上。流量0.5L/S左右。沖刷水進入泵腔。
　　3、每次待沖刷水或冷卻水敞開五分鐘后，再發起潛水渣漿泵。
　　4、每次中止潛水渣漿泵五分鐘后，再停沖刷水或冷卻水。
　　5、機械密封不允許在無沖刷水或冷卻水狀態下工作，或干沖突工作。

1. The pressure of the cooling water for the seal of the external scour machine should not be too high. Generally, the pressure should not be higher than 0.05 MPa and the flow rate should be about 0.3 L/S. Generally, it can move naturally.

2. The pressure of the cooling water of the inner scour seal should be more than 0.1 MPa higher than that of the working pressure in the sealing chamber. The flow rate is about 0.5L/S. The flushing water enters the pump chamber.

3. The submersible slurry pump shall be launched after the flushing water or cooling water is opened for five minutes each time.

4. Stop scouring or cooling water five minutes after each suspension of submersible slurry pump.

5. Mechanical seals are not allowed to work without scouring water or cooling water or in dry conflict.
