The technology of mechanical seal installation requirements

    Technical requirements for installation

   Mechanical seal is belongs to the high precisionmechanical components, have greatly influence on theservice life of the correct installation and operation of it.We generally in accordance with the provisions of the Ministry of chemical industry standard oil.

    The installation of pump and mechanical seal with sometechnical requirements are as follows:

    1.Shaft bending: the maximum of not more than 0.05 mm;

    2.The rotor vibration swing: dynamic ring seal at the shaftnear is not greater than 0.06 mm;

The axial movement, 3 axis does not exceed ± 0.5 mm, if the belt shaft sleeve, do not allow the sleeve to loose;

   4.The alignment of the coupling error: for the gear coupling is not more than 0.08 ~ 0.10 mm (P2008C), for the elastic coupling is not more than 0.05 ~ 0.06 mm;(<0.05 practices end jump, jump <0.10)

    5.The gland (static ring seat) and sealed with the rabbetof shaft center line of the concentricity tolerance of 0.05 mm, flat contact with the gasket on the center line of theverticality tolerance value 0.03 ~ 0.05 mm, if not up to therequirements, the seal cavity to be processed;

    6.Install the ring sleeve end sealing ring, and the installation of a stationary ring gland sealing ring (orshell) of the end should be chamfered, and smoothed.

    1.In the installation, the demolition of mechanical seals to carefully, prohibited the use of hammer and the flat shovel, so as not to damage the sealing element. If the fouling removing when not, should be cleaned after theremoval.

    2.If the pump with mechanical seal at both ends, in the assembly, take care of each other in the disassembly process, prevent the care for this and lose that.

     3.To run the machine, and the sealing gland loosemove to happen, then the dynamic and static ring parts must be replaced, should not be re tightened to continue to use. After the original loose because of friction pairorbit would change, the contact surface of the seal is very vulnerable to damage.
