Step 5, the mechanical seal lock ring in stirrer mechanical seal device is installed fastening firm, unscrew four bolts of fixed adjustment packing ring, four pieces of adjustment packing rings are taken out, and piece card of four in stirrer mechanical seal device is unscrewed, shifted out;
Step 6, all fixing bolts are pressed the fastening method in diagonal angle by stirrer mechanical seal device fix in position, and firmly fastening, complete stirrer mechanical seal device seepage on-line tuning.
The cooling water getting final product turn on agitator mechanical seal device after completing starts the test-run a machine work of stirrer
Preferably, in step 2, spacer is crossed the center of circle quartering by one piece of circular pad and is made.
Preferably, in step 2, spacer be circular gasket, the external diameter of spacer is 35 ~ 45mm.
Preferably, in step 2, the thickness of spacer is 1.2 ~ 1.7mm.
Preferably, spacer be circular gasket, the external diameter of spacer is 40mm.
Preferably, the thickness of spacer is 1.5mm.
Preferably, adjusting pad is metallic shim.
In contrast correlation technique, the processing mode can only carried out after seepage appears in mechanical seal looking around or directly mechanical seal be changed, method provided by the invention may be provided in line and changes, can low cost, be free from risk and fundamentally head it off.
[embodiment]
Below in conjunction with embodiment, the invention will be further described.
