The working efficiency of sand pumps is mainly related to the following factors:

1. Types and designs of sand pumps: Different types and designs of sand pumps may have varying efficiency when handling materials with different properties and operating conditions. For example, the shape, size, and structure of the impeller can affect pumping capacity and efficiency.

2. Material characteristics: including particle size distribution, concentration, density, viscosity, and corrosiveness of the material. Larger particles, high concentrations, high viscosity, or corrosive materials can increase the difficulty of pumping, thereby reducing work efficiency.

3. Speed: The speed of the sand pump has a significant impact on its working efficiency. The appropriate rotational speed can enable the sand pump to operate under optimal conditions and improve pumping efficiency.

4. Pressure difference between inlet and outlet: The larger the pressure difference between inlet and outlet, the greater the resistance that the sand pump needs to overcome, which may lead to a decrease in work efficiency.

5. Pipeline layout and resistance: The length, diameter, number and angle of bends of the pipeline can all affect the flow resistance. Excessive resistance will reduce the efficiency of the sand pump.

6. Sealing performance: Good sealing can reduce leakage, improve the volumetric efficiency of the pump, and thus improve work efficiency.

7. Operation and maintenance: Regular maintenance, such as cleaning, lubrication, and replacing worn parts, can ensure the normal operation of the sand pump and maintain high work efficiency.

8. Installation and debugging: Correct installation and debugging can ensure the alignment of the sand pump shaft and balance of the impeller, which helps to improve work efficiency and extend service life.

Detailed Photos

Our company is a professional manufacturer of sand pumps, dredgers, and underwater operation equipment!
A cutter suction dredger is a type of dredger that uses a rotating cutter to loosen the soil on the riverbed or seabed, mixes it with cement to form mud, sucks it into the pump body through a suction pipe, and sends it to the discharge area through a discharge pipe.
It mainly consists of the hull, cutter, bridge, mud pump, power device, and other parts. It has the advantages of high dredging efficiency and wide applicability, and is widely used in port, waterway dredging, and land reclamation projects.

Our products have been tested and transformed for many years and have now reached a very successful state. Our products are sold to multiple countries and regions around the world (Azerbaijan, Russia, Pakistan, Liberia, Tanzania, Democratic Republic of Congo, Ghana, Sierra Leone, Nigeria, Madagascar, Gabon, Thailand, Singapore, Malaysia, India, North Korea, Philippines, Morocco) and have been successfully delivered to customers for use!
No matter which country you use it in, we will send professional installation workers to be responsible for installation, debugging, and training operators!

We have 6 manufacturing factories covering an area of 38000 square meters, with 180 professional sales personnel, 580 workshop workers, 200 installation workers, and 180 after-sales workers (non fixed).

Here are some common dredger parameters:

**Captain * *: Usually ranging from tens to hundreds of meters.

**Ship width * *: varies depending on different models.

**Draft depth: generally several meters.

**Total installed power * *: From several thousand kilowatts to tens of thousands of kilowatts.

**Dredging depth * *: may range from tens of meters to tens of meters.

**Mud discharge distance: several hundred meters to several kilometers.

**Dredging yield: tens to thousands of cubic meters or even more per hour.

**Twister power * *: several hundred kilowatts to thousands of kilowatts.

Of course, the specific parameters of different types and specifications of dredgers will vary greatly.
The main structure of the ship (floating body) is manufactured by welding specific ship plates, which will not cause dangerous problems such as deformation, corrosion, and leakage. Equipped with power, it can be matched with diesel power or electric power according to customer requirements and on-site conditions. The sand pump uses a impeller type wear-resistant high-pressure sand pump, which has the advantage of high suction depth and long conveying distance, making it very durable. Simultaneously equipped with a high-pressure water gun (suction type) or a fully hydraulic reamer head (suction type) to assist in the operation of the sand pump. The tail is equipped with positioning stakes to firmly fix the ship and prevent it from swinging and working stably. The control is button based, simple and convenient, requiring only 1-2 people to operate.

Installation Instructions

When choosing a dredger, both the quality and price of vulnerable parts are important, and it cannot be simply said which is absolutely more important.

The importance of the quality of vulnerable parts is self-evident. High quality vulnerable parts mean longer service life, fewer failures and maintenance frequencies, which can ensure stable and continuous operation of the dredger, reduce downtime and production losses caused by damage to vulnerable parts. In the long run, it is crucial to ensure the overall efficiency and efficiency of the dredger.

And the price cannot be ignored. A reasonable price can make procurement costs more economical, especially for some budget limited situations where price factors need to be considered to a certain extent to ensure the overall economy of the project.

In an ideal situation, it is necessary to seek a more reasonable price while ensuring a certain level of quality, in order to achieve a balance between quality and price. At the same time, it is necessary to comprehensively consider various factors such as the overall performance, manufacturer reputation, and after-sales service of the dredger. It is not only necessary to focus on the quality or price of vulnerable parts, but also to conduct a comprehensive evaluation and balance to choose the most suitable dredger.

The product is easy to disassemble and assemble, using bolts for connection and assembly. It meets the size of the container and is easy to transport. During transportation, there will be no loss of parts or corrosion of the paint surface. After safe transportation to the site, specialized installation workers will come to assist in installation.

The following is a general operation tutorial for diesel engine driven sand pumps:
1. Preparation before startup:
-Check if the diesel engine oil and circulating water tank cooling water meet the specified values.
-Check if the oil in the high-pressure water pump, sand pump, and gearbox is sufficient (all are 40 # diesel oil).
-Add water to the high-pressure water pump.
2. Start the diesel engine:
-Start the high-pressure water pump diesel engine, and at the same time, start the sand pump main engine to idle for a few minutes. After the water temperature and oil temperature gradually increase, close the connecting clutch.
-Gradually increase the diesel engine speed to normal speed (approximately 1450 rpm).
-Close the high-pressure water gun gate valve, open the vacuum master ball valve, and open the vacuum valve.
-Raise the main engine speed of the sand pump to 1300 rpm, lift the sand suction faucet above the water surface, and see a continuous flow of clean water in the sand suction faucet. Place the sand suction faucet back below the water surface, reduce the diesel engine speed to below 1000 rpm, then close the gearbox clutch, and then increase the diesel engine speed to above 1300 rpm and below 1500 rpm (before the new machine enters the running in period, the speed should be controlled below 1350 rpm). After a period of time, a large amount of water flows out at the sand outlet, indicating that the sand suction pump has been filled with water. At this time, close the vacuum valve and the vacuum main valve, open the high-pressure water gun gate valve, and gradually lower the sand suction faucet.
3. Sand pumping operation:
-After the sand pump is filled with water, the sand can be sucked. Pay attention to controlling the sand suction concentration to avoid low concentration affecting equipment production capacity and high concentration blocking the pipeline.
4. Shutdown:
-If the equipment needs to be shut down during operation, the sand suction faucet needs to be raised first.
-After shutdown, check if all components are functioning properly and clean the equipment and surrounding environment.

Please note that relevant safety operating procedures must be strictly followed during the operation process to ensure the safety of personnel and equipment. Meanwhile, depending on the actual situation, it may be necessary to make appropriate adjustments to the operating steps. If you have any questions about the specific operation, it is recommended to refer to the equipment manual or consult a professional.
