Company Profile

 

In today's field of engineering construction and resource development, sand pumps are playing an increasingly important role. Today, let's talk in detail about sand pumps.
The sand pump, as a specialized equipment for extracting sand and mud water mixtures, has greatly improved the efficiency of sand mining and dredging operations.
The core components of this pump are the impeller and pump body. The strong centrifugal force generated by the high-speed rotation of the impeller can quickly suck the liquid containing sand particles into the pump and transport it out under high pressure. Moreover, in order to cope with the wear and tear of sand and gravel, the impeller and pump body of the sand pump are usually made of high wear-resistant materials.
The application scenarios of sand pumps are very extensive. In river management, it can quickly remove accumulated sediment in the river and improve the water flow condition of the river; In land reclamation projects in coastal areas, sand pumps can continuously extract sea sand and provide raw materials for land expansion; In sand mining sites, it is an indispensable equipment to efficiently complete sand mining operations.
However, there are also some issues to note when using a sand pump. For example, it is necessary to choose appropriate models and specifications based on actual working conditions to ensure that their performance can be fully utilized. At the same time, regular maintenance and upkeep are also essential to extend the service life of the sand pump and ensure its stable operation.
In short, sand pumps have become a powerful tool in modern engineering construction and resource development due to their efficient and reliable performance. I believe that with the continuous advancement of technology, it will bring us more surprises and convenience.

Our profession is extracting sand from water, extracting various minerals, long-distance transportation in water, and cleaning weeds on the water surface!

The working principle of sand pump is mainly based on the action of centrifugal force.

After the sand pump is started, the motor drives the impeller to rotate at high speed. When the impeller rotates, the liquid between the blades also rotates accordingly. Due to the centrifugal force, the liquid is thrown from the center of the impeller towards the outer circumference, and energy is obtained, resulting in an increase in the pressure and velocity of the liquid.

At the center of the impeller, a local vacuum is formed due to the liquid being ejected, resulting in negative pressure. Under negative pressure, the liquid containing sand is sucked into the center of the impeller.

The sand water mixture that is sucked in is transported to the outlet of the pump through the flow channel inside the pump casing under the action of the impeller, and finally discharged through the outlet pipeline, achieving the process of sand extraction.

Different types and specifications of sand pumps may have differences in specific structure and impeller design, but overall, they rely on centrifugal force and negative pressure to complete the sand pumping work.

          A cutter suction dredger is a dredging tool that uses a rotating cutter to loosen the soil on the riverbed or seabed, mixes it with cement to form mud, and then sucks the mud into the pump body through a suction pipe and sends it to the discharge area. It is mainly used for dredging in inland lake areas and coastal ports, suitable for excavating soil such as sand, sandy loam, and silt. During the construction of the cutter suction dredger, the dredging, transportation, and unloading processes can be completed continuously in one go, resulting in high production efficiency.
The main structure of a cutter suction dredger includes the hull, cutter, suction pipe, pump body, and discharge pipe. The cutter is a key component of a cutter suction dredger, usually installed at the bow or side of the ship. By rotating the cutter, the sediment at the bottom of the water is crushed and mixed with water to form mud. The suction pipe is used to suck mud into the pump body, which transports the mud to the discharge area through the discharge pipe.

 

 
 

The construction process of a cutter suction dredger is generally as follows:
1. Construction preparation: including the formulation of construction plans, survey of construction areas, equipment inspection and commissioning, etc., then positioning the ship and accurately positioning the cutter suction dredger in the construction area. According to the wind and flow conditions, set up the windward and upstream anchors in order to stabilize the ship's hull.
2. Lowering the cutter bridge: Lower the cutter bridge to the designated cutter position for excavation.
3. Soil conveying: The soil crushed by the cutter is transported to the designated mud receiving area through a high-power centrifugal mud pump and a discharge pipeline.
4. Construction monitoring: Real time monitoring of excavation depth, instantaneous water level, cross-sectional view of excavation trench or underwater three-dimensional map and other data to ensure construction quality and safety.
5. Moving ship position: According to construction needs, move the ship to the next construction area by retracting and releasing anchor cables and adjusting the position of the winch.
The specific construction process may be adjusted appropriately based on engineering requirements, soil quality, hydrology, and other factors. topic
