So far, this series of mud pump has been successfully for domestic 80 m3 / h - 5000 m3 / h cutter-suction dredger provides dozens of Taiwan, for our country of the Yangtze river, the Yellow River, huaihe river in the pearl river delta, such as rivers and lakes, ports of dredging dredging and made tremendous contributions to the circumference from land.
From 2006 to 2012, our company has is 10000 m3 / h trailing suction hopper dredger, 11000 m3 / h trailing suction hopper dredger, 18000 m3 / h trailing suction hopper dredger provides the nation's largest mud pump.This series of mud pump to fill the domestic blank of large mud pump mainly rely on import, received a good economic and social benefits, at present the series of vessels operating in good condition.
U good Marine general structure
1) simple structure
Wn 200 wn - 200 type pump adopts single pump shell, single-stage single-suction cantilever horizontal structure, according to the connecting way of gear box can provide two kinds of typical structure, namely take one with pump box type bracket type, bring their own bracket type lubrication way for grease lubrication of oil lubrication.
600 wn - 1200 wn, TK1000 TK1200 cabin pump adopts double pump shell, single-stage single-suction cantilever horizontal structure, bring their own bracket, lubrication method for thin oil lubrication.Submersible pump adopts single pump shell structure, in order to reduce the pump, easy to lift and move.
2) before using detachable type, match with special tools, easy to tear open outfit, easy maintenance
Taken the dredging performance is good
1) good cavitation performance, ensure the pump suction capability is strong, also can achieve greater dig deep and higher concentrations of inhaled.
2) impeller passage width, flow ability
3) performance curve steep fall, make the mud pump have stronger adaptability to the change of row spacing
4) by changing the pump rotation speed, or change the impeller diameter can realize a variety of pump performance
Taken the wear-resisting performance is good, over-current components long service life
1) impeller, sheath, lining board flow components with strong anti-wear alloy cast iron, hardness is not less than 50 HRC, while has a strong impact resistance, high abrasion resistance.
2) full consideration in the process of product design service life of the matching between parts, wear parts replacement cycle is basically the same, reduces the maintenance and replacement costs.
Taken the water loss of small, high efficiency, low power consumption
The adoption of advanced hydraulic model, the mud pump efficiency level is high, an average of 2-3% higher than the import of mud pump and so on the same production, fuel consumption is lower.
Taken the shaft sealing is reliable, no leakage
200 wn - 500 wn dredging pump shaft seal adopts mechanical seal or mechanical seal packing compound seal.600 wn - 1000 wn dredging pump shaft seal adopts screw sets of L type rubber seal, the sealing device of oil 3 way L type sealing ring and a threaded shaft sleeve.In order to improve the life of the shaft seal, equipped with sand water separator, guarantee the quality of the shaft seal water.
It is mainly used for trailing suction hopper dredger and ground suction dredger.Also for river sand mining and mining ships.
