What Kind of Suction Dredge Pumps are Suitable for Inland River Dredging

What kind of suction dredge pumps are suitable for inland river dredging? Followed are some suggestions.

Inland river is different from large river and sea. There are large particles or twining solids such as mixed garbages, weed, bricks; Mud is more than sand, it may dry up in summer.

At present, cutter suction dredgers is often equipped with suction dredge pumps and vertical sand pump units, the cutter suction dredgers can be used with excavator ships for inland river dredging. Besides this, there are other methods for inland river dredging.

1. For a dry river, there is no water source nearby, excavator or artificial way is suitable but not sand pump. This method is time-consuming and laborious. The working efficiency is lower.

2. The river water is very shallow. Vertical suction dredge pumps equipped with high pressure water gun are a better choice. It has the features of easy operation, high suction concentration, high efficiency, thorough cleaning up. The disadvantages are that it needs manual operation and the discharge distance is not so long.  If the conveying distance is long, horizontal suction dredge pumps can be used as booster pumps. The sand extracted by several vertical suction dredge pumps gathers to one horizontal sand pump, then is conveyed to discharge destination.

3. When the river has sufficient water supply, a variety of sand pumping equipment can be used in conjunction with each other. If there are a lot of weeds in the river, the mowing boat can clean up the weeds at first, then the cutter suction dredger cleaning up sediment and stones. The big particle gravel sand pumps are suitable to be equipped on the cutter suction dredgers, because the large particle suction dredge pumps have the characteristics of wide channel, non blockage, strong wear resistance. The largest particle diameter allowed to pass is 20cm, it is the best choice for this working condition.

Generally, the river clearing project is more complicated, we can choose the suction dredge pumps according to actual working condition.

Tai’an Ocean Pump Co.,Ltd. is professional in designing and producing suction dredge pumps, sand suction pump, slurry pump, dredging pump, sand dredgers, etc. We can supply the customers different construction plans according to different construction conditions. On the base of rich experiences in the Yellow River dredging and dyke strengthening, our products have been widely used in our domestic market and gotten good praise. Our products are famous for high efficiency, wear-resistance, long distance conveying. In the recent years, the submersible mud pumps designed and produced by our company are hot sale in our domestic dredging sites and mining enterprises. The advantages of the sand dredging machine are durable, wear-resistance and easy operation. At the same time, the export sales of the sand pumps are getting better and better.

Combined Sand Pumps were Delivered to Zambia for Sand Dredging

Combined sand pumps consist of two sets or more sand pump units. One of the sand pump units is used as main sand suction pump, the others are booster pumps. So combined sand pumps can achieve high-concentration suction and long-distance transportation of sediment. The design of combined sand pumps combines the advantages of the high suction sand pump and the high lift sand pump, the advantages are complementary, and the benefit of sand pumping is maximized.

Selection Background of Combined Sand Pumps

On November 15, 2018, the Zambian customer consulted the international business department of Ocean Pump about long distance sand transporting. The working conditions were as follows.

1. The combined sand pumps were mainly used for extracting fine sand without large particles and garbage.
2. The water depth of working area was 2-5m, the maximum extraction depth was 10m, the discharge distance was 2000m, and almost no discharge height.
3. They had 6 inch pipelines, and could make sand dredger according to the size of sand pump units.
4. There was no transformer in local area. But there was a 200kva generator set, output voltage was 400v, the frequency was 50Hz.
5. The sand output was more than 20m³/h.

6 inch Large Particle Sediment Pump was Delivered to Jiangxi

Large particle sediment pump, also known as big particle gravel sand pump, is a kind of powerful sand suction pump which is specially designed for the extraction and long distance transportation of large particles such as pebbles, river garbage, etc. Large particle sediment pump is precisely cast with high quality and high wear resistant material. The maximum particle size allowed to pass can reach to 240 mm. Large particle sediment pump has the advantages of wear resistance, corrosion resistance, high sand absorption efficiency, large over-flow particles and good anti-cavitation. Large particle sediment pump is widely used in reservoir, river, lake, sea, etc.

Jiangxi customers used the ordinary 6 inch sand suction pump, the sand output is 30m square meters per hour, the conveying distance is 100m. Because the sand pump was made of ordinary cast iron, and there were so many pebbles in the river, the over flow parts were worn seriously and needed to be replaced frequently, this increased the maintenance cost.

So the customers were considering purchasing a new set of sand dredging pump. They required that the sand output should be more than 30m3/h, and the conveying distance should be about 200m. Our engineers recommended 6 inch large particle sediment pump ZS150.
The sand pump casing, impeller and guard plate are made of high chromium alloy, so the sand pump machine has the feature of high wear resistance, it is suitable for the working condition of many pebbles in the river.

Material Differences of Centrifugal Slurry Pump

Centrifugal slurry pump is commonly used in pumping systems that move sand deposits to a long distance. Centrifugal slurry pump has good price and high performance in our sand pump machines. Small size and volume make centrifugal slurry pump easy to operate, transport and maintain. Centrifugal slurry pump is widely used for tailing, sediment, sand or slurry extraction in the power plant, river, lake, pond, etc.

Every manufacturer of sand dredging pump in the market claims to produce wear-resistant centrifugal slurry pumps. What are the differences? Except the working conditions, sand pumping machine rotation speed and other factors, which kind of casting material is better? This article elaborates on these issues.

1. Material A05, also known as chrome 27, material label Cr27, is mainly used in casting the over-current parts of large particle gravel pump. It is originally used by Australian WAMAN Company in the mining project. This material is a kind of wear-resistant white iron, with the advantages of corrosion resistance and erosion resistance. Compared with other casting material, it contains nickel instead of molybdenum.

2. Material Cr26.It is the over-current parts material of Centrifugal slurry pump. Cr26 is mainly used in submersible slurry pump and vertical slurry pump. Cr26 contains 26% chromium, and also contains nickel, molybdenum, copper. Cr26 has high wear resistance and high performance, so it is suitable for high speed sand suction pump.
   
   
   
   

3. Material Cr28, mainly used in marine sand pump and centrifugal slurry pump. The chromium content is 28%. It also contains nickel and molybdenum. It is harder than Cr26, and has good tensile properties. The application range is very wide.

3. Material Cr15Mo3. Compared with above three casting material, Cr15Mo3 has strongest wear resistance and is also the hardest casting material. But the production of molybdenum and nickel is low, so the price of Cr15Mo3 is very high. The casting parts cost of Cr15Mo3 is twice as much as high-chromium alloy. However China is vigorously mining nickel and molybdenum ore, the market prospect is good.

Wear resistance of the sand pump over-current components is mainly depends on the content of carbon. Then adding trace elements such as silicon, manganese, phosphorus, nickel, chromium, molybdenum, copper, aluminum, boron, vanadium, tin, etc. High wear resistance can be realized by changing the proportion of the elements. In the actual selection, customers can select different types of centrifugal slurry pump and over-current components materials according to the requirements of the sand output.

Tai’an Ocean Pump (OCEAN Pump) Co., Ltd. is the leading centrifugal slurry pump and sand dredger solutions manufacturer, supplier and exporter in China.We have more than 30 talented sand pump experts and 15,000 square meters factory.
