Translation: A sand pump (or sand suction machine) is a type of mechanical equipment used for extracting and transporting sand and gravel, and it is widely applied in fields such as municipal engineering, water conservancy, and construction.

Core Working Structure (Power and Conveying Core)

This part is crucial for realizing the sand pumping function, mainly responsible for generating suction, extracting sand and gravel, and conveying them.
Sand pump assembly: The core power source, usually a centrifugal pump or a slurry pump. It generates negative pressure through the high-speed rotation of the impeller, sucks the mixture of sand, gravel and water into the pump body, and then sends it into the conveying pipeline after pressurization by centrifugal force.
Power system: Provides power for the sand pump. Common forms include motors (for land or small equipment) and diesel engines (for large equipment or scenarios without power supply). Some equipment is also equipped with reducers to adjust the rotation speed to adapt to different working conditions.
Conveying pipeline: Connects to the outlet of the sand pump and is used to convey the extracted sand and gravel mixture to designated locations (such as sand carriers, sand yards). The pipeline is mostly made of wear-resistant steel or polymer materials to withstand the scouring and wear of sand and gravel.
