Product Description:




The pump has a single-stage,single-suction and double pump shells structure. Seen from the inlet end, therotary direction of the right pump is counterclockwise while the left one isclockwise. The pump is the domestic largest dredging pump applied to 13500m3trailing suction hopper dredger of Shanghai Waterway Bureau.

It is widely applied todredging, silt clearing and hydraulic filling with rivers and lakes, ports anddocks all over the country such as, YangtzeRiver Basin, YellowRiver Basin, Liaohe River Basin,Pearl River Delta, Huaihe river basin, etc. The products are also sold toEurope, Middle East and Southeast Asia.  

dredging pump is new type dredging pump,making full use of advanced CAD software ,siming to china 's river lake and sea situation:they haven't been repaired for many years and now they are in great need to dredge and fill hydraulically.

this series of dredging pump has characteristic features:easy installation ,long-life  service ,high efficiency,reliable bearing lining and good economical efficiency ,this type of pump can meet dredging ship's requirements completely and each set of dredging pump has passed the inspection issued by CCS

Q:What is the difference between a cutter suction dredger and a trailing suction dredger?
TSHD is installed through the chain of dredge bucket will be dug out of the bottom mud, stored on a ship or barge dredger edges.
Q:Advantages and disadvantages of trailing suction dredger for trailing suction dredger
In dredging, sediment laden with large amounts of water is transported to the dumping area, thereby affecting production. The suction boat can be used in infrastructure dredging and maintenance dredging, but not in narrow water areas
Q:The famous type of cutter suction dredger
The leading dredging expert, Jan De Nul, will further expand its fleet of ships, which will build a self propelled suction dredger, named JDN8069, at the Croatia shipyard UljanikBrodogradiliste. After completion, the ship will become the world's largest suction suction dredger, compared with Luxemburg, JDN dredging group currently has the world's largest suction suction dredger, "J.F.J. DeNul", power 50%. JDN8069 ship is expected to be delivered in early 2017, global operations.
Q:What is the working principle of a cutter suction dredger?
To locate the pile as the center circle movement by sliding around the hull swing cutter knife and realize dynamic soil, can pump to thousands of meters away
Q:What are the crew members on the dredge?
The dredge work generally is not very tired, after all, the mechanization of things, the need for artificial little ~ ~ for one is general and maintenance of turbine operation, as well as the ship fuel supply etc..
Q:Who knows what's the name of the biggest dredger in China?
Tianjin Waterway Bureau of the pumping strength slightly stronger its name to "day" at the beginning of the word, is the largest dredger and Tianqi Tianlin, nominal production in my impression is 4200m /h fand the two sister ship, is currently the largest dredger.
Q:How much dredging can the 4000 side /h suction dredge dredge in one day? Soft silt
The "4000 party" per hour he refers to is under design conditions. If you are digging soft mud, the hourly rate is higher than 4000, and I now ship according to Holland IHC, originally designed to be 3500 parties, we call the 4500 party. In fact, if the excavation of soft silt, pipelines in 5 kilometers or so, we can produce more than one hundred thousand per day. The instantaneous yield can reach 7000 square hours per hour. I wonder what the power of your so-called 4000 party pump is
Q:The working principle of a trailing suction dredger
The ship is equipped with one or several sets of centrifugal pumps, centrifugal pumps for absorbing water and mud from the bottom of the vessel, into the mud tank. These operations are carried out on the voyage, while air while digging, mud tank fill to throw mud mud area, through the Bilge mud. Handle cases
Q:Does dredging dredger need relevant qualification?
This should be based on the requirements of your local department, which is not required in general
Q:3800m3 cutter suction dredger
3800m3 bucket wheel dredger is at the end of the last century according to the Ministry of transportation "based on domestic design and construction, the introduction of equipment key technology policy, the Yangtze River Waterway Bureau presided over the development of construction, Shanghai 708 Institute of design, Wuchang shipyard built China's first inland new dredger. The ship's key power equipment, dredging equipment, hydraulic systems were provided by German SKL company, United States Ellicotte (Aili, Kurt) company, the United States Dennison hydraulic company. This ship has been officially delivered to the Yichang Waterway Engineering Bureau of the Yangtze River. The name of vessel is No. 1.Bucket wheel cutting device in the river near the mouth of the soil suction, and by rotating the bucket wheel by cutting soil and water into high concentration mud, directly transported to the suction suction head of the top tube, rely on the suction centrifugal pump, the suction pipe has certain vacuum. The mud suction head, suction tube at the top end of the suction pipe, through the mud pump pressure after the mud through the mud discharging pipe into the mud barge or transported to the mud field. Through positioning piles, positioning piles, landing gear and traversing winch, the positioning of dredger, longitudinal forward movement and lateral swing of ship are achieved, and the purpose of continuous excavation of river bed soil is achieved.
