Precautions when installing the pump seal

1) Before installation, please carefully check the assembly of the number of parts is sufficient, the components are damaged, especially the dynamic and static ring with or without bruises, Pump Seal cracks and deformation defects. If there is a problem, repair or replace the new spare parts.

2) Check that the chamfering of the sleeve or gland is appropriate and that it must be trimmed if it does not meet the requirements.

3) Mechanical seals The components and their associated assembly surfaces must be cleaned with acetone or anhydrous alcohol before installation. The installation process should be kept clean, especially moving, static ring and auxiliary sealing elements should be no impurities, dust. Moving, static ring surface coated with a layer of clean oil or turbine oil.

4) The upper cover should be carried out after the coupling is correct. Pump Seal Bolts should be tightened evenly to prevent the gland section skew, with a stopper or special tools to check the points, the error is not greater than 0.05 mm.

5) Check the gap (and concentricity) of the gland with the outer diameter of the shaft or sleeve. Pump Seal It must be ensured evenly and the tolerance of the points is not more than 0.10 mm.

6) spring compression should be carried out in accordance with the provisions, not allowed to have too large or too small phenomenon, the required error ± 2.00 mm, over the General Assembly to increase the cross-section pressure, accelerated section wear. Pump Seal Too small will cause less than the pressure can not play a sealed role, spring loaded in the spring seat to move flexible. With a single spring to pay attention to the spring of the rotation, Pump Seal the spring should be the rotation of the axis of the opposite direction of rotation.

Water pump sealing effect is to prevent the pump impeller and pump shell between the abrasion, improve the pump inlet water flow state, improve the pump efficiency.

A pump is a machine that delivers liquid or pressurizes the liquid. It transfers the mechanical energy or other external energy of the prime mover to the liquid to increase the energy of the liquid. It is mainly used to transport the liquid, including water, oil, acid and alkali solution, emulsion, Pump Seal suspension liquid and liquid metal. It can also transport liquid, gas mixture As well as liquids containing suspended solids. Water pump sealing performance of the technical parameters are flow, suction, head, shaft power, water power, efficiency, etc .; according to different working principle can be divided into volume pumps, vane pumps and other types. Volume pump is the use of its studio volume changes to transfer energy; vane pump is the use of rotary blade and water interaction to transfer energy, Pump Seal a centrifugal pump, axial flow pump and mixed flow pump and other types.
