Company Profile

The specialized sand pump for port terminal construction is a specialized equipment used for port terminal construction and maintenance. It is mainly used for extracting and transporting mixtures of solid particles and liquids such as sediment, mud, ore, etc.

This type of sand pump usually has the following characteristics and advantages:
-Wear resistance: Due to the possibility of solid particles in the extracted medium, the flow components of sand pumps are usually made of wear-resistant materials to extend their service life.
-* * High head and large flow * *: It can meet the requirements for head and flow in port and dock construction, effectively transporting sediment and other materials to designated locations.
-Anti clogging design: Adopting a special impeller structure or anti clogging device to reduce the risk of pump clogging and improve work efficiency.
-* * Mobility * *: Some sand pumps are designed to be movable, making it easy to arrange and operate flexibly on the construction site.
-* * Used in conjunction with other equipment * *: It can be used in conjunction with other equipment such as dredgers and pipelines to form a complete construction system.

When choosing a specialized sand pump for port and dock construction, the following factors need to be considered:
-Construction requirements: Determine the required parameters such as head and flow rate based on specific construction tasks and requirements.
-* * Medium characteristics * *: Understand the properties of the extracted medium, such as particle size, concentration, etc., in order to choose the appropriate type of sand pump and wear-resistant materials.
-* * Reliability and maintainability * *: Choose sand pumps with reliable quality and easy maintenance to reduce malfunctions and downtime.
-* * Supplier Reputation * *: Choose a supplier with good reputation and after-sales service to ensure the quality of equipment and after-sales support.

If you need more detailed and accurate information, it is recommended to consult a professional sand pump manufacturer or relevant technical experts.

Detailed Photos

 

          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 following is a tutorial on the operation of specialized sand pumps for inland rivers and lakes, which includes common faults and solutions:

**Operation Tutorial for Inland River and Lake Special Sand Pump**

1, Preparation work
1. Check whether the sand pump and related supporting equipment are in good condition, and whether all connecting parts are tightened.
2. Confirm that the power supply or power source is normal.
3. Clean up debris around the sand pump to ensure the safety of the work area.

2, Start the sand pump
1. Start the power device, such as an electric motor or engine, according to the operating procedures.
2. Observe the operation status of the sand pump to ensure that there are no abnormal sounds or vibrations.

3, Regulation and monitoring
1. Adjust the flow and pressure parameters of the sand pump according to actual needs.
2. Pay close attention to the working status of the sand pump, including operating sound, temperature, etc.
3. Pay attention to observe whether the conveying pipeline is blocked or leaking.

4, Precautions during operation
1. It is strictly prohibited to carry out illegal operations or maintenance during the operation of the sand pump.
2. Avoid inhaling large solid particles or debris to prevent damage to the sand pump.
3. Regularly inspect and maintain relevant equipment, such as filters.

5, Common faults and solutions
1. * * Insufficient traffic * *:
-Reasons: impeller wear, pipeline blockage, low speed, etc.
-Solution: Replace the impeller, clean the pipeline, check and adjust the speed.
2. * * Head reduction * *:
-Reasons: impeller damage, seal ring wear, gas content in the liquid, etc.
-Solution: Repair or replace the impeller, replace the sealing ring, and remove gas from the liquid.
3. * * Excessive pump body vibration * *:
-Reason: Impeller imbalance, loose anchor bolts, bent pump shaft, etc.
-Solution: Perform dynamic balance correction, tighten the anchor bolts, correct or replace the pump shaft.
4. * * Bearing heating * *:
-Reason: Poor lubrication, damaged bearings, pump shaft and motor shaft not concentric, etc.
-Solution: Add or replace lubricating oil, replace bearings, and adjust concentricity.
5. * * Sealing leakage * *:
-Reason: Seal wear, improper installation, etc.
-Solution: Replace the seal and reinstall it correctly.

6, Shutdown operation
1. Gradually shut down the power unit in the prescribed order.
2. Close relevant valves and switches.
3. Clean and inspect the sand pump and its surroundings to prepare for next use.

Please strictly follow this operation manual and follow relevant safety regulations to ensure the normal operation of the sand pump and the safety of operators. If there are any problems or abnormal situations during the operation, the machine should be shut down in a timely manner for inspection and handling.

The above content is for reference only, and you can adjust and supplement it according to the actual situation. If you need more detailed and accurate information, you can further consult the manufacturer or professional technical personnel of the sand pump.

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
