Referring to fig. 1 and fig. 2 together, the present embodiment provides a shaft seal mounting device for a fluidization fan, which includes a semicircular first mounting assembly 11 and a semicircular second mounting assembly 12 matched with the first mounting assembly 11.
Two ends of the first mounting component 11 and two ends of the second mounting component 12 are connected in a one-to-one fit mode to form the circular mounting component 10.
Specifically, two ends of the first mounting assembly 11 are defined as a first end 111 and a second end 112, two ends of the second mounting assembly 12 are defined as a third end 121 and a fourth end 122, in the assembling and connecting process, the first end 111 of the first mounting assembly 11 and the third end 121 of the second mounting assembly 12 are matched and assembled, and the second end 112 of the first mounting assembly 11 and the fourth end 122 of the second mounting assembly 12 are assembled and connected.
It is worth emphasizing that in this embodiment the mounting member 10 has an inner diameter equal to the inner diameter of the mounting hole in the fluidized fan in which the shaft seal is to be mounted. Therefore, before the shaft seal is installed, the clamp is sleeved on the outer side of the shaft seal, then the clamp is aligned with the installation hole of the shaft seal to be installed, and the copper rod is used for knocking the piston body to enable the shaft seal to be separated from the clamp and directly transited into the installation hole.
Preferably, the inner diameter of the mounting member 10 is equal to the outer diameter of the shaft seal to be mounted, so that the mounting member 10 can be tightly sleeved on the outer surface of the shaft seal, and the damage of the shaft seal during mounting due to the fact that the shaft seal is not fastened in place is avoided.
In an alternative embodiment, the inner diameter of the mounting member 10 may be 241mm and the thickness may be 10-14mm, i.e. the outer diameter of the mounting member 10 may be 261 and 269 mm.
