Installation and service of the seals:
 1: before the start of sealed cavity filled with liquid shall be maintained.For solidification of the medium, the application of steam heat seal chamber to melt medium.Prior to start turning, in order to prevent sudden start caused by the soft ring fracture.

2: for the use of pump mechanical seal oil system, should start the sealing oil system.Stop after the last stop in sealing system.

3: hot oil pump stop can't stop immediately after sealing oil cavity and end face seal cooling water, should be end face seal oil temperature has dropped below 80 degrees, can stop the cooling water, so as not to damage the sealing parts.
