| Abstract: | In the passage,it refers to that when the pump P104B of hydro cracking unit in the catalyst plant of refinery is in operation,sometimes it may be in malfunction that is oil and gas leak and even cause fire.It seriously affected long-term stability of hydro cracking unit and security,as well as environmental protection.To analyze the cause of mechanical seal in failure for Pump P104B,and considering the work of mechanical seal,I have improved the seal of type in unit and the system of cooling,as well as process of operation.Practice has proved that we can get a good sealing effect and economic benefits after transformation. |
