Though the dredging industry is not something on most people�s minds, it is closely related with the national economy and the daily life of every citizen. Hong Kong is the only natural deepwater port among China�s 1,400 ports. If it was not for the dredging industry, a total of 90% of China�s shipping lanes with overseas countries would be blocked.

The industry has also made remarkable contributions in island-making in recent years. With the help of the industry, the famous tourist attraction West Lake in eastern China�s Zhejiang province has completed comprehensive water treatment. At present, China has more than 1,000 types of dredging dredging vessels, ranking the third in the world, which can be described as a large dredging country. However, dredging vessels are small in size.

By 2006, the vast majority of dredgers in the dredging industry in China were imported from abroad. Zhong Wenwei, chairman of Tianjin Communications Bureau of China Communications, said that the dredging vessels in China have gone through the process of importing whole ships, designing domestically from overseas and designing domestically and domestically.

For international comparison, in 2015 a self-propelled cutter suction dredge ordered at Croatian shipbuilder Uljanik Brodogradiliste by Jan de Nul would have a total installed diesel power of over 40,000 kW, making it some 50% more powerful than the group"s J.F.J. De Nul, currently the largest cutter suction dredge in the world. The cutter power will be 8,500 kW and the cutter ladder will weigh around 2,000 tonnes. These figures are unrivaled and make the vessel the ultimate tool for dredging hard rock. The vessel, initially designated JDN8069, featured one MAN 14V48/60CR and two MAN 9L48/60CR engines plus three step-up Renk Rheine gearboxes for a diesel-electric plant.

The design of previous seven large self-propelled cutter suction dredgers served as a basis for the new CSD concept. The new vessel will offer approximately 50% more power than J F J De Nul, which is the world�s biggest cutter suction dredger currently operational. JDN8069 will have an overall length of 151.3m, breadth of 36m, draught of 5.75m and dredging depth of 45m. It will be outfitted with accommodation facilities for carrying 67 personnel.

A dredge is a ship, boat, barge or other floating platform equipped with a pump-type excavation system. The excavation system removes material (e.g., debris, aggregate, ore, contaminates, etc.) from a lake, canal, harbor, river, ocean, pond, or stream bed by digging through the material, agitating the material and/or simply drawing suspended material to create a slurry from a mixture of collected material and water, and pumping the slurry through conduits to a desired location onboard the vessel, in the water, or on land. Dredging can be associated with many different industries, including conservation, construction, mining, and transportation.

There are several types of dredges that are commonly classified as mechanical, hydraulic, hybrid, or pneumatic. Mechanical dredges use digging buckets such as a clamshell suspended by a cable from a crane, an excavator on a fixed arm, or dragline buckets suspended by a cable from a crane. Hydraulic dredges add water to sediment to create a slurry that can be pumped by pipeline to the dewatering site or to a hopper dredge. Hybrid dredges use mechanical devices to remove the sediment and then to mix it with water to create a slurry that is then pumped to a dewatering site. The hybrid process option includes various pumps that can move slurries with higher solid content than traditional hydraulic dredges, so that much less water is added to make the slurry. Pneumatic dredges are similar to hydraulic dredges, except that they use pneumatic systems to move the dredged material.

Dredging generally involves the enhancement or preservation of navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation�the natural process of sand and silt washing downstream�gradually fills channels and harbors. Dredging often is focused on maintaining or increasing the depth of navigation channels, anchorages, or berthing areas to ensure the safe passage of boats and ships. Vessels require a certain amount of water in order to float and not touch bottom. This water depth continues to increase over time as larger and larger ships are deployed. Since massive ships carry the bulk of the goods imported into the country, dredging plays a vital role in the economy.

The two primary types of hydraulic dredges are the cutterhead pipeline dredge and the self-propelled hopper dredge. Advantages of cutterhead pipeline dredges include their ability to excavate most materials, to pump directly to a disposal site, to dredge almost continuously, and to dredge some types of rock without blasting. However, cutterhead pipeline dredges have limited capability in rough weather; have difficulty with coarse sand in swift currents; and, for the most part, are not self-propelled. In addition, the necessary pipeline can be an obstruction to navigation and, when handling debris in sediment, the removal efficiency is diminished.

Self-propelled hopper dredges can operate in rough water and move quickly to a jobsite under their own power. The dredging operation does not interfere with other traffic. Work progresses quickly and is economical for long haul distances. Hopper dredges are limited to work in deep waters, but they cannot dredge continuously. Excavation is less precise than with other dredges, and this dredge type has difficulty dredging steep banks and consolidated materials. Specialty dredges such as the dustpan dredge and sidecaster dredge are used to remove loosely compacted coarse-grained material at rapid shoaling sites or in areas where the sediment is needed.

Pipeline conveyance might require the use of booster pump(s), depending on the distance to the disposal location. Disposal locations that are less than approximately 1 mile will not likely require a booster pump. Typically, the water content of the slurry ranges from seventy percent (70%) to one hundred percent (100%), with pipe line velocities maintained at between seven (7) feet to fifteen (15) feet per second in order to achieve adequate particulate suspension. Because of the high water content of the slurry and high pump velocities, disposal of the slurry is a problem. A common method of dealing with the disposal problem is to pump the slurry into a lagoon or settling basin and let the excess water run-off.

A suction dredger is one of the oldest type of suction dredgers that utilizes a mud pump to suck unbreakable dredged soil. When dredging soil needs to be broken, the method of high pressure water jetting is often used. Suction dredgers are somewhat similar to barges, with cable systems such as bucket dredgers. In the hull is equipped with a cabin and a mud pump chamber, the use of centrifugal pump, suction pipe through the cabin into the hull open file. With a tower crane or winged crane and winch can be put into the water pipe along the pipette is installed with one or more nozzles jet pipe nozzle is installed near the mouth of the suction inlet with a grille to prevent the pebbles , Stones or other debris into the straw and mud pump. As the straw is lowered into the bottom of the mud, a mixture of water and sand (mud) is sucked and the dense, dredged soil is crushed and mixed with water to form a slurry or suspension, with the help of a high-pressure water jet system, for suction. During dredging, a deep pit is formed in the dug area, and silt flows along the slope to the mouth to suck up the sediment. Controlling the cable moves the dredger.

Dredging with this type the dredging depth accuracy is very low, but its performance of digging sand and low-density soil is very good. Some suction dredgers are equipped with a submersible mud pump or a submersible mud pump combined with an inboard mud pump. Working offshore (offshore) requires the installation of a dedicated wave compensator on the drawworks winch. The mud sucked up by the dredger is drained to the mud barb bound by the dredging vessel via the mud pipe. In the mud barge, sediment settles and the water is forced to overflow out of the mud barge hatch, sometimes using a float pipe connected to a relay pump to direct the aspirated dirt to the dumping area.

The cutter suction dredger is also a type of open-end vessel, with two heavy-duty positioning steel piles at the stern. During the construction dredging, the positioning steel piles are used to keep the ship"s position. One of the steel piles is always lowered into the mud to keep the position. Some cutter suction dredgers, near the stern of the middle, is equipped with a positioning pile trolley, the positioning of the steel pile on the dredging of the main positioning pile. The truck can be dredged forward without moving the main stake. In a short period of time, another auxiliary positioning stake may be placed in place of the main positioning stake.

These new land areas rely on a huge Chinese "dredging team." Interestingly, these vessels did not exist 15 years ago. Since 2001, China intends to expand and improve the then poor quality dredger fleet in order to meet the growing domestic demand for deeper waterways and harbors. This investment was successful. The dredging capacity of China has increased from 300 million cubic meters in 2001 to over 1 billion cubic meters in 2009, making it the number one dredging power in the world.

The number of dredgers in China is the largest in the world. Together with the large and advanced dredging vessels in China, the Chinese dredger team boarded the championship. Between 2005 and 2012, China built 20 trailing suction hoppers dredgers with a capacity of 9,000 cubic meters or more. From 2004 to 2011, at least 44 cutter suction dredgers were built in China, including those built in 2010, auch as the world"s third-largest self-propelled cutter suction dredger "Whale".

Tobee Pump™ TG Dredge Pump are the most comprehensive range of centrifugal gravel sand pumps for use in mining, chemical and general industry applications. The horizontal dredge pump are designed for heavy duty applications such as mining, power sector,dredging river,and tailings as well as specialty applications, which are used for continuous pumping of high abrasive, high density sand and gravels.

5. Wide application.The dredge pump can be used in various kinds of soil quality. Generally,the dredge sand pump is matched with an impeller with 3 or 5 pieces of vane. At the same time,the impellers can be provided with various diameters and vane types to suit kinds of working conditions.

As one of the most commonly used seals for rotating shafts, the packing seal can come with low-flush or full flush arrangement which uses flushing water to prevent media from escaping the pump housing. This kind of seal is suitable for use under all pumping conditions. In situations where corrosive solids or high temperature might be encountered, Teflon or aramid fiber is used as the packing material for the gland. For high abrasion conditions, a ceramic shaft sleeve is available.

The combination of impeller and expeller creates the pressure needed to seal against leakage. Together with the gland seal or lip seal which is used as the shut-down seal, this type of seal can handle sealing requirements for applications where full-flush gland seal is impractical due to lack of water on the site, or sealing water is allowed to enter inside the pumping chamber to dilute the slurry.

TG Dredge Pump utilizes a leak-proof mechanical seal design which allows easy installation and replacement. Other types of mechanical seal are among options to suit the slurry pump for various pumping applications.

WN series Marine sand dredge pumpis a single-stage single-suction cantilever centrifugal pump. This series of mud pumps has the characteristics of excellent dredging performance, long service life, high efficiency, reliable shaft seal, and significant comprehensive economic benefits. It can fully meet the requirements of dredgers. Requirements for mud pumps.

At present, this series of mud pumps has successfully provided supporting facilities for various types of dredgers in China, successfully replaced imported mud pumps, and used for dredging and cleaning of ports in the Yangtze River Basin, Yellow River Basin, Pearl River Delta, and Zhunhe River Basin. The silt blowing and filling has made a great contribution.

Among the flow parts of WN type Marine sand dredge pump, the impeller, sheath, front and rear guard plates (wear-resistant lining plates) are made of strong wear-resistant alloy cast iron with a hardness of not less than 58HRC. High anti-abrasion properties.

When using a wear-resistant horizontal Marine sand dredge pump, how should the operator operate and what should be paid attention to in use?The operator should stick to the work position. Before starting the wear-resistant horizontal Marine sand suction pump, check whether the parts are in good condition and whether the coupling is locked. Slowly turn the coupling or pulley by hand to check whether the transmission part will be stuck, and then start it after confirming that everything is normal:

The wear-resistant horizontal Marine sand dredge pumpshould be filled with water before starting the pump. When adding water, first close the water outlet valve, open the air valve, and then close the air release valve after filling the water. After starting, wait for the pump to run at full speed. The water outlet valve can be opened gradually, and the water will flow out at this time.

Pay attention to the operation of the sand pump at any time during the pumping process. If there is water leakage, air leakage, abnormal water output, heating of the packing and bearing, blockage of the filter screen, abnormal sound, and excessive temperature rise of the motor, it should be stopped immediately for maintenance.

The water surface of the inlet pool should be kept at a certain height. If it drops too low, the wear-resistant horizontal sand pump should stop running, and the wear-resistant horizontal sand pump should not be idling for a long time without water:

When shutting down, the outlet valve should be closed first, and then the motor should be turned off, so as to avoid damage to the impeller or the bottom valve and other components due to the backflow of high-pressure water in the outlet pipe during sudden shutdown. When it is stopped in winter, the drain valve should be opened, and the water in the wear-resistant horizontal sand pump and the pipe should be released to avoid frost cracking.
