How to ensure the quality of mechanical seal installation


First of all to figure out what is a mechanical seal, in fact it is a rotary mechanical oil seal device, it is to purchase mechanical seal on a pair or more than one end perpendicular to the axis of rotation in the fluid pressure and compensation mechanism elastic (or magnetic) In combination with the role of the auxiliary seal, the fluid leakage is prevented by sticking together and sliding the purchase of the mechanical seal.  Therefore, the installation quality requirements are very high. How can we ensure that the mechanical seal installation quality is excellent?
       Mechanical seal installation precautions:
    1, radial shaft beating equipment should be less than or equal to 0.04 mm, the axial mechanical seal, the momentum is not allowed more than 0.1 mm;
    2 sealing parts and equipment should be kept clean during installation, the sealing parts should be cleaned, seal intact, prevent impurities and dust into the sealing parts;
    In 3, the installation process is strictly prohibited, hit the beat, so as not to damage the mechanical seal friction seal failure;
    4、The surface contacted with the seal should be coated with a layer of clean mechanical oil during installation so that it can be installed smoothly;
    5, the installation of static ring gland, tighten the screws must be uniform stress, the vertical static ring end face and the requirements of the axial line of the;
    6, installed after the hand pushes the movable ring ring, can make flexible move on the shaft, and has a certain elasticity;
    7, after the installation with the hand disc shaft, shaft should be no weight feeling;
    8, the equipment must be filled with medium before operation, in order to prevent friction and the sealing failure.
