China Shandong Haohang Intelligent Equipment Co., Ltd
The sand scraper pump in marine dredging equipment is mainly used in the following scenarios:

1. River dredging: Clean up silt, sand, and debris in the river to improve its navigation capacity and water flow conditions.

2. Port construction and maintenance: excavating sediment in port construction to provide a foundation for the construction of port facilities; Remove sediment during daily maintenance of the port to ensure its normal operation.

3. Lake dredging: used to remove sediment from the bottom of the lake, improve the water quality and ecological environment of the lake.

4. Coastal engineering: For projects such as land reclamation and coastal protection, extracting sea sand for engineering construction.

5. Deepening and widening of waterways: Increase the depth and width of waterways to enable safe passage of large vessels.

6. Reservoir dredging: Clearing the sediment at the bottom of the reservoir to increase its storage capacity and regulation capacity.

7. Water conservancy engineering construction: providing transportation and treatment of sediment materials for water conservancy projects.

8. Sand collection operation: Collect sand from rivers, lakes, seas and other water bodies for use in construction materials and other fields.
There are usually several types of sand scraping pumps in marine dredging equipment:
-* * Centrifugal pump * *: The liquid is thrown out by centrifugal force, generating suction and pressure to achieve liquid transportation.
-* * Positive displacement pump * *: It is composed of a stator, rotor, and pump chamber that sucks in and out liquids through volume changes.
-* * Shear pump * *: It cuts liquid into small particles and transports them through shear action, and is commonly used to process liquids containing solid particles.

When choosing a sand scraper pump, multiple factors need to be considered, such as the properties of the conveying medium, flow rate, head, working environment, etc. At the same time, it is necessary to choose according to specific dredging needs and the characteristics of ship equipment to ensure that the sand scraping pump can meet the actual working requirements.
