Fixing and Applying Directions of Mechanical Seals
| 1. Select Appropriate mechanical seal to match the materials
according to work conditions and host machine equipment. |
| 2. The radial acting deviation for the shaft(shaft sleeve) of the
installed mechanical seal shall be 0.04mm by maximum while the
axial movement value of the rotor shall be no more than 0.1mm. |
| 3. The seal cover (or shaft cover) of the stationary ring of the
installed mechanical seals,the vertical degree of the seal face
should be 0.04mm by maximum. |
4. When installing the mechanical seals,the shaft(shaft
sleeve),seal chamber,seal face as well as the mechanical seal face
should be 0.04mm by maximum. |
| 5. When conveying medium of over high or low temperature,with
medium which are easy catch fire,easy for explosion.Related
mechanical seal standards must be referred to take appropriate
measures such as quench,rinsing,coolong and filtrating. |
| 6. Appropricate lubrication must be choosen when mechanical seal is
installed.The installment size of the mechanical seal must be
guaranteed to the installment instruction. |
| 7. Before the machine starts running,the hermetic compartment shall
be full of medium and well lubricated.Dry friction which may lead
to the damage of the air-tightness is strict forbidden. |
Question 4: How does your factory do regarding quality
control?
Answer: Quality is priority. We always attach great
importance to quality controlling from the very beginning
