With the development of the industry, the slurry pump technology has become more and more mature, and its application has become more and more extensive, and it has played a good role in transporting high-concentration, abrasive and corrosive fluids. Among them, the slurry pump plays a very important role.

The slurry pump guard plate, sheath and impeller are the key parts of the slurry pump's over-current components. Since the conveyed materials contain various solid particles and acid-base ions, serious wear and corrosion are caused to the slurry pump's over-current components. Therefore, the slurry pump flow components have high wear resistance and corrosion resistance requirements. At present, the materials of the flow parts of slurry pumps are generally wear-resistant alloys, rubber, ceramics, and polyurethane. Among them, the alloy has high hardness and good wear resistance, but poor corrosion resistance. Ceramics have high hardness, wear resistance and corrosion resistance, but are brittle and difficult to use in slurry pumps.

Polyurethane has excellent wear resistance and corrosion resistance, and wear is fatigue wear. Rubber is a material with good conveying effect for slurry with small particle size, good anti-wear and anti-corrosion properties, and good resistance to acid and alkali corrosion, and its application is continuously promoted. Among them, Lianhe Shengxin produces wear-resistant rubber with advanced technology, good wear resistance, better wear resistance than alloy, and it is convenient and quick to use, and easy to install, maintain and replace.

In addition, the efficiency of the slurry pump has a great relationship with the size of the gap between the front guard plate and the impeller. If the gap between them is too large, the volume loss of the slurry pump will increase, which will lead to flow and lift. decrease, and the efficiency of the slurry pump will decrease. At the same time, when the gap is too large, it will also affect the shaft seal components, resulting in an increase in the back pressure of the impeller, the packing seal will fail, the slurry will leak, and the service time of the shaft seal components will be greatly shortened.
