Heat transfer oil pump can be installed according to different conditions of different forms of mechanical seals, such as built-in single-ended flat horizontal and unbalanced, double-ended balanced and unbalanced, external mechanical seal, etc., so the choice of seal according to different forms, its The use of methods and precautions are also different, the specific circumstances generally have the following points: 1, the general mechanical seal is suitable for cleaning non-suspended particles in the medium, the newly installed piping system combined storage tank should be carefully cleaned to prevent solid impurities Mechanical seal face. 2, the use of mechanical seal in the crystallization of the medium, should pay attention to regular cleaning, stop before restarting the mechanical seal on the crystal clean. 3, remove the mechanical seal should be careful, non-hand cone, iron and other percussion. Demolition should be clear dirt. 4, strictly check the moving ring and the ring of the grinding end, does not allow any minor scratches, bump and other defects. 5, Correctly adjust the amount of compression spring, so that it is appropriate degree of tightness, so as to avoid excessive wear or leakage. 6, on the external rinse of the mechanical seal, start the rinse solution should be opened before the seal cavity is filled with sealing liquid, stop the pump when the first stop, turn off the seal rinse solution.
