The main reason for the mechanical seal failure of the slag oil pump

The main reasons for seal failure in general slag oil pumps include end face liquid film failure, material and medium incompatibility, and installation issues. The specific pressure of the end face of the slag oil pump is an important performance parameter of the mechanical seal. The specific pressure of the end face should be within a certain range (usually 0.4 MPa to 0.7 MPa for internal mechanical seals), and the mechanical seal end face of the slag oil pump should be matched to form a liquid film between the sealing surfaces. The damage situation is as follows:
