First, the structural characteristics of slurry pump mechanical seal:

Third, the application of slurry pump mechanical seal:

Containing solid particle content for the harsh conditions and high, mainly for the alumina plant, flue gas desulfurization system, power plant ash handling system, causing direct economic losses of pulp and paper industry, use of cartridge mechanical seal, easy installation , not axial adjustment of the size.

Fourth, slurry pump mechanical seal installation:

1, check the installation of the mechanical seal models, specifications and correct;

2, check the installation of slurry pumps and associated mechanical seal parts of the dimensional accuracy, the relationship between geometric accuracy and compliance with technical requirements. Mainly in the following areas:

(1) Installation of mechanical seal parts of the shaft (or sleeve) of the radial runout tolerance, shaft (or sleeve) of the surface finish and the outside diameter tolerances.

(2) the sealed chamber and the side face of the gland with positioning shaft (or sleeve) the center line of the vertical degree of tolerance.

(3) Install the shaft seal ring (or sleeve) of the end of the installation of mechanical seals the ends of the shell structure of the pore chamfering and finish.

(4) mechanical seals of the shaft when the axial displacement of the work.

3, the installation of mechanical seal process, should be kept clean, and not allowed to use tools to beat sealing elements to prevent damage and destruction;

4, the installation, dynamic and static ring surface should be coated with a layer of clean oil and turbine oil. Auxiliary ring (including the moving and stationary ring ring ring ring) to be painted before installation, but also a layer of clean oil or turbine oil, to ensure a smooth installation;

5, the stationary ring seal trap in the static ring back later, in a sealed cover, to pay attention not to hurt the stationary ring face to face with the end caps to ensure the stationary ring vertical center line, and pay attention to the stationary ring to the back of the anti-rotation slot aligned against resellers, but not in contact;

6, the mechanical seal of the rotating part, rely on the spring seat and the axis of two fixed screw and tighten the screws, to ensure that the work of the spring length.
