1) Select
appropriate bearing materials. All friction pairs at the bearing are made of
high-quality silicon carbide. High quality silicon carbide has high
purity,
Silicon carbide content is more than 99%, resistant to ammonia
corrosion, with high strength, elasticity, toughness and wear resistance, which
greatly improves the anti extrusion and impact capacity of the bearing, and its
service life is more than 10 times that of other sliding bearings (such as
graphite).
2) Select proper thrust bearing clearance when installing the
rotor. By trial installing the rotor on the bearing body and pushing the rotor
to one side, the maximum clearance between the industrial bearing toilet parts
of the magnetic pump can be measured (when the bearing is normal, the maximum
axial displacement j generated by the rotor is between 0.13-0.15, which is
adjusted to 0.3-0.5 mm. This clearance range is conducive to the formation of
the liquid film between the gaps, reducing the friction between the two friction
pairs of the thrust bearing, and reducing the impact force when being
impacted
3) Optimize operation in process to minimize or avoid large
fluctuation of working conditions; The pump reversing period shall be extended
to 2 months to minimize the adverse effects of frequent pump reversing on the
magnetic pump.
4) The improved magnetic pump pays attention to the process
operation during operation, showing the inherent characteristics of the magnetic
pump. At the same time, it has good operation performance, free of maintenance
for a long time, reliable operation, and a maintenance cycle of about one year,
which ensures the long-term operation of the equipment.
