It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
The primary function of a drainage pump is to collect and remove water from a specified area. Most commonly used in basements, crawl spaces, and construction sites, these pumps are equipped with a float switch that activates the pump when water reaches a certain level. Once the water is detected, the pump will turn on, drawing the water into its casing and expelling it through a discharge pipe to a designated drainage area. This process continues until the water level drops below the float switch, at which point the pump turns off.
The production of rubber slurry pumps begins with the selection of high-quality materials. The primary components of these pumps include the pump casing, impeller, and wear components, all of which are crucial for efficient performance. Rubber, due to its excellent resilience and wear resistance, is widely used in constructing these components. Factories often source synthetic rubber, such as polyurethane, to enhance durability further, especially in harsh operating conditions.

Slurry pumps are vital for transporting mixtures of liquid and solid particles, commonly found in mining, construction, and agricultural applications. Unlike standard pumps, slurry pumps must withstand harsh conditions, such as high wear rates from abrasive materials like sand, gravel, and metals. The design of these pumps, especially their blades, plays a crucial role in their efficiency and durability.
