Wear resistance: The guard plate is in direct contact with the slurry, so it needs to have good wear resistance. It is usually made of high-strength alloy materials and can withstand the strong centrifugal force generated by high-speed rotation and the impact of high-concentration slurry.
Long service life: Since the guard plate is parallel to the direction of slurry movement, the guard plate has a longer service life than the sleeve and impeller.
Slurry pump is a kind of equipment widely used in the industrial field, mainly used to transport slurry containing solid particles. As an important component to protect the pump body and extend the service life of the pump, the performance and selection of the slurry pump guard plate have a vital impact on the operating efficiency and service life of the slurry pump. This article will briefly introduce the function, selection and maintenance of the slurry pump guard plate.
1. Function of slurry pump guard plate
The main function of the slurry pump guard plate is to protect the pump body from the scouring and wear of solid particles. During the operation of the slurry pump, solid particles will scour the pump body, which will cause serious wear of the pump body in the long run and even affect the normal operation of the pump. The design of the slurry pump guard plate can form a barrier between the pump body and the solid particles, effectively reducing the scouring of the pump body by solid particles, thereby extending the service life of the pump.
When selecting a slurry pump guard plate, the following aspects need to be considered:
1. Material: The material of the slurry pump guard plate needs to have good wear resistance and corrosion resistance. Common materials include wear-resistant cast iron, high chromium cast iron, wear-resistant steel, etc. It is necessary to select a suitable material according to the actual use environment and medium characteristics.
2. Thickness: The thickness of the slurry pump guard plate is also one of the factors that need to be considered when selecting. If the thickness is too small, it may not be able to withstand the erosion of solid particles; if the thickness is too large, it may affect the efficiency of the pump. It is necessary to select an appropriate thickness based on the actual situation while ensuring wear resistance.
