Wear Plates (front & rear liner plate)

Wear Plates (front & rear liner plate)
Product Description
The pump wear plate of slurry pump is one of the overflow parts of the
slurry pump. Due to the transported materials containing various solid
particles and acid-base ions, it causes serious wear and corrosion to the
overflow parts of the slurry pump. Therefore, there are high wear and corrosion
resistance requirements for the overflow parts such as the front guard plate of
the slurry pump. At present, the front guard plate of slurry pump is generally
made of wear-resistant alloy, rubber, ceramics and polyurethane. The alloy has
high hardness and good wear resistance, but poor corrosion resistance. Ceramics
have high hardness, wear resistance and corrosion resistance, but they are
brittle, so they are difficult to be used in slurry pump.
In addition, the efficiency of the slurry pump has a great relationship with
the gap between the front guard plate and the impeller of the slurry pump. If
the gap between them is too large, the volume loss of the slurry pump will
increase, which will reduce the flow and head, and then the efficiency of the
slurry pump will be reduced. At the same time, if the clearance is too large,
it will also affect the shaft seal components, resulting in the increase of the
back pressure of the impeller, the failure of the packing seal and the leakage
of the slurry, which will greatly shorten the service time of the shaft seal
components.
